Tax controversies usually arise as a consequence of the audit attributions of the Mexican tax authorities (Servicio de Administración Tributaria – SAT), which lead to tax assessments of alleged unpaid amounts.
Tax controversies may also arise as a result of the denial of the refund of a favourable balance or of an undue amount paid by the taxpayer.
In both instances, tax controversies at the federal level have their origin in the issuance of an official letter by the tax authorities containing an assessment or a rejection of a refund.
Most tax controversies are related to income tax or value-added tax, as these are the principal sources of tax revenue for the Mexican government, and are triggered by every kind of commercial activity, so almost every productive entity is obliged to pay those contributions.
Two specific issues can be identified in the vast majority of controversies, since the authorities challenge the effective execution of the acts that trigger tax effects: (i) transfer pricing adjustments, and (ii) the substance of the transactions.
As of 2020, an additional issue has given rise to a large number of controversies, although it does not imply any assessment or economic liability: the cancellation of taxpayers’ electronic seals to issue electronic invoices.
As per the 2020 reform to the Federal Tax Code, the legal causes that entitle the authorities to cancel these seals have been increased as a way of preventing the issuance of artificial invoices by shell companies, a practice that has had a major evasion effect to the detriment of tax collection.
Additionally, it is important to consider that a new rule entered into force in 2021, according to which Mexican tax authorities will make public the parameters of what they consider to be reasonable profit margins, deductions and effective tax rates for each economic sector.
Although the SAT’s parameters are not mandatory and the aforementioned notice is not a formal audit, it is foreseeable that audits will be carried out, and eventually assessments will be issued against the companies that do not comply with the parameters issued by the authorities.
There are no statistics available to determine the values involved in each specific case.
Once the authorities have initiated an audit, it is unlikely that a controversy can be avoided or mitigated.
If the taxpayer is not able to demonstrate with sufficient evidence that there has been no avoidance, it is entitled to rectify its tax situation by accepting the observations made by the authorities during the audit. Depending on the stage the audit has reached when the corrections are made, a reduction of fines and penalties may occur.
Another method to avoid a tax controversy is to enter into an alternative dispute resolution process, as outlined under 6. Alternative Dispute Resolution (ADR) Mechanisms.
The base erosion and profit shifting (BEPS) recommendations made by the OECD to combat tax avoidance, and the modification of domestic legislation following those recommendations, have not contributed substantially to reducing or increasing tax controversies; they have been used and applied by the authorities to audit taxpayers’ obligations, but have had little influence on the number of controversies.
As of 2020, several BEPS recommendations have been included in Mexican legislation, such as:
It can be expected that these rules will be applied at audit procedures, but not that they will substantially increase or diminish the number of audits.
Regarding double tax treaties, Mexico has not amended a significant number of the international agreements it has signed related to such matters. Nevertheless, Mexico signed the Multilateral BEPS Treaty, although it is not yet in force as it has not been ratified by the Senate.
The taxpayer has no obligation to guarantee the tax assessed in order to be able to lodge an administrative or judicial claim against the corresponding ruling.
Nonetheless, if the assessment is not paid or guaranteed, the authorities have full capacity to carry out a foreclosure procedure as stated in the Federal Tax Code.
There are only two cases in which any foreclosure file is suspended without the need of a guarantee: (i) if the taxpayer challenges the assessment through an administrative claim, and (ii) if the assessment is challenged through a substance trial (as explained in 4.2 Procedure of Judicial Tax Litigation).
The relationship between tax assessments and a criminal filing against the taxpayer is explained in 7. Administrative and Criminal Tax Offences.
As a rule, entities to be audited are selected randomly. Nevertheless, the authorities adopt specific criteria to determine an audit against a specific company or group. Entities must be one of the following.
The SAT’s Chief Officer has declared, publicly and privately, that high income taxpayers and multinational groups will be carefully audited, with no exception, in order to increase the collection of taxes.
In addition, there is the legal possibility of initiating a direct audit against a specific taxpayer or group, when the authorities have knowledge that that entity has taken part in any misconduct, such as issuing artificial invoices that correspond to operations that, in substance, did not take place.
Operation Master Plan
In January 2023, the SAT released its Operation Master Plan for 2023 (the Master Plan), which outlines the main goals and strategies in terms of audit and collection for this year.
The Master Plan identifies the following economic sectors as ones that will be prioritised by the SAT in 2022:
It also specifies the topics and transactions on which the SAT’s auditing efforts will be focused, which include:
In order to audit and collect taxes from taxpayers in the aforementioned industries and with regard to the preceding list of transactions, the SAT has outlined the following strategic actions:
Effective Tax Rates
During 2023, the SAT has issued several publications on its website regarding what it considers to be the reasonable effective tax rate parameters in different sectors of the economy, for the fiscal years 2020 and 2021.
Such effective tax rates have been calculated according to the annual tax returns submitted by the taxpayers in the corresponding sector.
The effective tax rate is defined as the amount of income tax effectively paid, as a proportion of the total taxable income received by the taxpayer; ie, this parameter does not consider legitimate deductions that companies can take and the application of NOLs of previous years, as permitted by statute.
It is foreseeable that audits will be triggered against taxpayers that do not comply with these effective tax rate parameters.
Nevertheless, it is important to bear in mind that such parameters are not mandatory for taxpayers and that they are fully entitled to demonstrate before the authorities at the audit stage, or even before the courts, that deductions, NOLs or other issues were legally applied in order to determine the amount of tax paid in the relevant tax year.
It is to be expected that during 2023 tax authorities will issue further publications and parameters on the effective rate for other sectors of the economy and for the years 2020, 2021 and 2022.
Authorities may initiate an audit at any time, unless the statute of limitations period has been exceeded.
The legal term to conduct an audit is 12 months. The period may be extended to 18 months when the audited taxpayer is part of the financial system, or to two years if the authorities request information from a foreign tax agency, or if the audit involves transfer pricing issues.
When the audit ends, within the aforementioned period, the authority has six months to issue an official letter and notify the results of the assessment.
The statute of limitations period is five years from the date the taxpayer files its ordinary tax return, or from the day any amended return is filed but limited to the issues that were modified.
When an audit is initiated, the statute of limitations period is suspended but in no case can it exceed six years and six months.
In some exceptional cases, the statute of limitations period may be extended up to ten years.
There are two main types of audit: those that take place at the authority’s headquarters (revisión de escritorio) and those that occur on the taxpayer’s premises (visita domiciliaria). There is no general rule, and the authority executes both options equally.
As a rule, audits are based on printed documents, although the taxpayer may submit documents and information in a digital format.
A new type of audit has recently been introduced by Mexican law: the electronic audit, which is based on the electronic information that taxpayers are obliged to submit monthly through the electronic systems implemented by the authorities.
Auditors put a special focus on requesting that the taxpayer demonstrate, through documentary evidence, the substance of the transactions that trigger tax effects (mainly deductions and creditable VAT).
Contracts, invoices and payment receipts are no longer sufficient evidence to demonstrate that a certain transaction took place – ie, that a service was effectively provided or merchandise was acquired.
Auditors also place an emphasis on the taxpayer demonstrating, for example, that a service provider effectively has the technical capabilities to render the service.
Additionally, auditors request that the taxpayer demonstrate the business reason for executing a specific transaction, instead of any other alternative.
Until 2019 there was no rule of substance over form in Mexican legislation; therefore, the analysis of the substance of taxpayers’ activities was made from a practical point of view.
As of 2020, however, a GAAR is in force according to which the SAT is entitled to ignore the tax effects of legal acts lacking a business reason, but that create a tax benefit for the taxpayer; therefore, it can be expected that the substance of such transactions will also be challenged from a tax point of view.
It is also foreseeable that, as of 2023, the SAT will investigate whether the creditable VAT was effectively paid in cash to the services or goods providers who transferred the VAT.
The foregoing is due to a precedent issued by the Mexican Supreme Court of Justice in March 2023, according to which the only manner in which to pay the transferred VAT, in order to be credited, is in cash.
This means that, if the VAT is paid, jointly with the price of the goods and services purchased, by offsetting payables and receivables of the taxpayer with its providers, then the SAT will have a strong case to reject such crediting when considering any refund request or determining any VAT liability.
Such precedent could affect the calculation of VAT in future periods, and also lead to the review of previous months, including those in which any refund was authorised.
The increasing prevalence of rules concerning cross-border exchanges of information and mutual assistance between states has not increased the number of tax audits in Mexico.
However, Mexican authorities have used the mechanisms for exchanging information as an additional tool to audit companies that are part of multinational groups.
Mexican authorities have requested information from foreign tax agencies in audits, including those in the USA, the Netherlands, Luxembourg and Ireland.
From a strategic point of view, the key thing that a taxpayer must do during an audit is provide all the evidence necessary to demonstrate the substance of, and the business reason behind, the transactions questioned during that audit (please refer to 2.1 Main Rules Determining Tax Audits).
It is important to bear in mind that, according to a precedent of the Supreme Court of Justice, evidence that was not submitted at the audit stage or during the administrative claim will not be accepted by the courts in any subsequent judicial litigation.
Therefore, it is highly important for the taxpayer to provide the authorities with all the evidence to support the facts and the nature of the transactions carried out by the company. Legal arguments and the interpretation of the applicable laws may be stated before the courts, but no additional evidence may be rendered.
Certainty of Date
Additionally, a recent mandatory precedent from the Supreme Court has stated that, in order to be a valid support for the existence and substance of a transaction, the documentary evidence must provide full assurance of its date of issuance or creation; that is, there must be complete certainty of the date a contract was signed or a transaction took place.
According to this precedent, there will be certainty over the date of a document when it is registered at the Public Registry of Property, or is ratified by a public notary or by the death of any of the parties in the contract.
Therefore, taxpayers would have to ratify each contract or agreement they enter into before a public notary, in order to provide certainty regarding of its date and, accordingly, to be a valid support for the tax effects derived from that transaction.
Nevertheless, among practitioners there is a broad discussion as to whether there are other means to provide certainty of the date of a piece of documentary evidence.
In order to challenge a tax assessment, the taxpayer can decide to either file an administrative claim or pursue a judicial trial, as the former is optional before initiating the latter.
The taxpayer has a legal term of 30 business days from the date of notification of the resolution to file the administrative claim before the legal area of the tax administration that determined the assessment.
Mexican law provides an additional term of 15 business days after the claim is filed to announce the evidence that will be rendered, and another 15 days to submit it.
Formally, authorities have a legal term of three months to issue a decision on the administrative claim. The absence of a resolution is considered a tacit negative decision and can be challenged by lodging a judicial claim before the Tax Court; however, it is unusual to appeal a tacit negative decision.
Taxpayers regularly wait until the resolution is issued since, within the time of the administrative appeal, there is no obligation to guarantee the assessment. When the claim is resolved or the tacit negative decision challenged, a bond or letter of credit, among other means, must be put in place to avoid any potential foreclosure procedure.
Judicial tax litigation is lodged either directly against the assessment or in order to challenge the decision of the administrative appeal.
The judicial claim is filed before the Federal Court of Administrative Justice (Tax Court), within a legal term of 30 business days from the date of the notification of the resolution to be challenged.
As mentioned in 4.1 Initiation of Judicial Tax Litigation, the taxpayer has a legal term of 30 business days to file the judicial claim before the Tax Court; tax authorities have a legal term of 30 business days to file their written response to the claim.
If evidence from an expert witness is to be rendered, the Tax Court will request that the experts appointed by the parties appear before the corresponding judicial officer to accept their assignment within the next ten business days after the response of the authority has been submitted. The experts will have an additional 15-day term in which to render their opinions.
If those opinions are contradictory, the Tax Court will appoint a third, independent expert to accept the assignment and render their report in the same terms as mentioned above.
Once the experts’ reports have been rendered, the parties will be granted a term of ten business days in which to prepare and file their written closing arguments.
The Court has a legal term of 45 business days to issue its verdict, but there is no legal sanction if it takes longer.
As of 2017, there is an additional form of the procedure available before the Tax Court: the so-called substance trial.
Through this special variant of the annulment complaint procedure, the taxpayer is entitled to argue only substance arguments before the Court, in order to challenge a tax assessment determined by the authority. This means that the plaintiff renounces its right to formulate legal arguments in order to demonstrate violations of the procedural rules that regulate tax audits.
Substance arguments must be understood as the interpretation of the applicable legal provisions, the qualification of the nature of the facts and transactions in question, and the evaluation of the evidence submitted at the audit.
Although the legal term to initiate the substance trial is also 30 business days, the terms of the internal phases of the procedure are shorter.
The most relevant difference between the ordinary trial and the substance trial is that, at the substance trial, there is a hearing in which both parties (taxpayer and authority) verbally present the main arguments to challenge or defend the legality of the assessment to the magistrates of the Tax Court.
The substance trial has become a highly recommendable option for taxpayers to challenge assessments that involve relevant or strategic issues, and that implicate an assessment of a large amount (as the threshold to file the substance trial is approximately USD325,000).
Another relevant advantage of the substance trial is that the law waives the taxpayer’s obligation to guarantee the assessment during the period in which the procedure takes place.
Documentary evidence is relevant in order to support the substance and business reasons for the transactions carried out by the taxpayer; however, no additional evidence can be submitted before the courts that was not rendered at the audit or with the administrative claim.
It is important to bear in mind that any document with which taxpayers intend to support their transactions has to provide certainty of its date of issuance, as explained in 2.6 Strategic Points for Consideration During Tax Audits; although it is not a legal requirement, it has been construed by the Supreme Court in a precedent that is mandatory for the inferior courts, such as the Tax Court.
The opinion of expert witnesses is appropriate evidence to be rendered at the judicial level if it is necessary to sustain any technical issue that goes beyond the legal interpretation of the law or the appreciation of the facts and evidence. Recurrent examples include expert opinions in accountancy, in economics regarding a transfer pricing controversy, or in engineering if the litigation is related to the oil industry.
Documentary evidence must be submitted with the claim. If not submitted, the court will grant an extra five-day term in which to do so. The expert opinion will be rendered according to the procedure described in 4.2 Procedure of Judicial Tax Legislation.
The burden of proof lies with the taxpayer in civil and administrative tax litigation, as the resolutions of the authority are deemed to be legal and lawful.
In criminal litigation, the burden of proof rests with the public prosecutor, as the Mexican Constitution establishes the presumption of innocence in favour of the defendant.
Documents and evidence must be submitted according to the legal terms, as explained in 4.2 Procedure of Judicial Tax Litigation and 4.3 Relevance of Evidence in Judicial Tax Litigation. It is important to remember that any evidence that was not rendered at the audit or with the administrative appeal will not be accepted by the courts, including the expert witness opinion.
There are several non-binding precedents stating that if the taxpayer did not submit the expert witness opinion as evidence with the administrative appeal, it cannot do so before the courts at the judicial litigation stage.
Additionally, documentary evidence must provide certainty of its date of issuance, according to a precedent of the Mexican Supreme Court of Justice.
Legal arguments also have to be stated at the claim, as no new arguments can be drafted at the appeal stage; any aspect that was not challenged at the claim may not be refuted at the appeal stage.
It is also important to bear in mind that legal arguments must directly challenge the legal grounds of the assessment and/or the resolution to the administrative appeal, its interpretation of the applicable legal provisions, the appreciation of the facts, and evidence rendered at the previous stages.
Legal arguments that do not aim to challenge these aspects will not be considered by the courts, as the purpose of a judicial claim is to refute the concrete legal grounds of a resolution that determines a tax assessment.
During a judicial claim there is no legal chance to enter into a settlement; these kinds of agreements between the tax authorities and the taxpayer can only be reached as explained in 6. Alternative Dispute Resolution (ADR) Mechanisms (in order to initiate such a process, it is necessary that no assessment has been determined).
At the same time, during a judicial trial, the question of whether or not to pay the assessment has no impact on the outcome of the litigation process. On the contrary, the taxpayer has to decide – when the corresponding resolution is notified – if the assessment is paid or guaranteed.
If the taxpayer decides to pay, this does not interfere with its right to litigate, but any interest or increase due to inflation will be accrued in its favour. This may be an important cash outflow for the company.
Expert reports shall be submitted following the process and terms explained in 4.2 Procedure of Judicial Tax Litigation, when the controversy relies, even in part, on technical issues that go beyond the interpretation of the law.
The jurisprudence issued by the Supreme Court of Justice and the Circuit Court is mandatory for the Tax Court. However, not every precedent is binding – only those that have ruled five cases in the same sense by a Circuit Court, or when the Supreme Court resolves a contradiction of criteria between two or more Circuit Courts.
Additionally, the legal considerations contained in the verdicts issued by the Supreme Court of Justice will be mandatory when they are approved by a specific majority.
On the other hand, international jurisprudence, doctrine (domestic or international) and other international documents are merely guidelines that courts can take into consideration, but which they are not obliged to defer to. Therefore, precedents other than domestic jurisprudence are rarely applied by the courts to resolve tax controversies.
However, according to Mexican legislation, the OECD Transfer Pricing Guidelines are applicable regarding the interpretation of transfer pricing rules.
As a rule, there is only one definitive form for appealing a verdict issued by the Tax Court, which is the direct constitutional injunction (juicio de amparo directo). In general terms, that is the proper remedy to challenge verdicts issued by courts.
The appeal is ruled on by a Circuit Court, which depends on the Federal Judicial Power.
There is no threshold or burden in order to appeal a verdict issued by the Tax Court, since it is a constitutional right for any private person or entity to challenge any verdict that causes any harm to its rights.
There are no limitations in terms of the nature or value of the controversy, unless the final and decisive stage of appeal, according to the law, has been reached and ruled on.
It is important to note that, if the verdict issued by the Tax Court is favourable to the taxpayer, the authorities are entitled to challenge that verdict through a petition for review, which will also be ruled by a Circuit Court.
As mentioned before, as a rule there is only one stage in tax appeal procedures: the direct constitutional injunction.
The procedure is simple, as this appeal cannot contain any legal arguments that were not stated during the judicial claim, and no new evidence may be rendered.
The legal arguments to be drafted at the constitutional injunction must challenge the legal grounds of the verdict issued by the Tax Court – ie, the interpretation of the applicable legal provisions, the nature of the facts according to the evidence, and the evaluation of the significance of the evidence rendered at the proceeding.
The only case in which there is a second stage for appeal is when the taxpayer claims the unconstitutionality of the legal provisions applied by the authorities and the Tax Court in order to determine and confirm the assessment, or when the direct interpretation of a constitutional rule is implied.
In both cases, the taxpayer can file an exceptional petition for review before the Supreme Court of Justice, which review will be limited to attending to the constitutional issues of the controversy that, in the Supreme Court’s view, may lead to an important and relevant precedent from a constitutional point of view.
It has become common practice for the Supreme Court to regard tax issues as not complying with the importance and relevance standard; therefore, the majority of the exceptional petitions for review are rejected, even when the controversy involves the constitutionality of a tax law, or its violation of an international tax treaty.
If the Supreme Court does not accept this extraordinary petition for review, there is no further remedy in order to challenge the decision.
Circuit Courts are formed by three magistrates, and their decisions are taken by majority or unanimity. One of the magistrates prepares a draft, which is then discussed and approved or rejected at a public hearing.
Magistrates are appointed by the Federal Judicial Council, the administrative agency of the Federal Judicial Power, from among the candidates who pass the corresponding public examinations.
The Justices of the Supreme Court of Justice are appointed according to the procedure stated in the Constitution: the President submits a shortlist of three candidates to the Senate, which then has to appoint one candidate through the favourable votes of two-thirds of the Senators.
Mexican law provides only one alternative dispute resolution (ADR) mechanism for tax disputes: mediation by the Mexican Taxpayers’ Ombudsman (Procuraduría de la Defensa del Contribuyente – Prodecon).
The purpose of the mediation process is to achieve a settlement between the taxpayer and the authorities regarding the true nature of the facts and transactions carried out by the taxpayer, and their tax effects.
This is not a controversy stage, but a collaborative procedure, in which both parties have expressed their intention to reach a settlement based on evidence.
Prodecon, acting as a mediator, provides all the legal means necessary to conduct the negotiation process by procuring the understanding, from each party, of the other’s position and the analysis of the evidence rendered by the parties.
The last stage of a review process, prior to determining an assessment, is the observations letter, in which the authority states in writing the issues discovered that may indicate an omission by the taxpayer. The audited entity will have a legal term of 20 business days in which to submit any evidence and express any legal arguments in order to demonstrate the contrary.
The relevance of said observations letter, or pre-assessment, is that the authority qualifies the nature of the facts and transactions as well as their legal effects.
Once this qualification is issued by the tax authorities, the taxpayer is entitled to initiate a conclusive agreement procedure before Prodecon. It is important to bear in mind that the corresponding request must be filed within a legal term of 20 business days after the notification of the observations letter.
In this request, the taxpayer shall indicate what it believes to be the true nature of the facts and transactions, and their legal effects, and propose the terms in which it considers a settlement should be reached.
The authorities will have 20 business days in which to agree with the taxpayer’s proposal, reject it or make a counterproposal.
If both parties demonstrate their disposition to achieve a settlement, Prodecon shall call for working sessions, where the taxpayer may submit additional evidence and express legal arguments in order to enter into a negotiation process regarding the proper evaluation of the facts, transactions, legal provisions and evidence provided by the parties.
At the end of the process, both the authorities and the taxpayer may reach a settlement regarding every issue in dispute or only some of them. The rest may be substance for an assessment and a litigation process.
If a settlement is reached, both parties must sign a written document in which the terms and conditions of the agreement and the corresponding duties applying to each of them are stated.
Prodecon’s role is to facilitate the negotiation process, make suggestions and express its point of view, which does not have to be followed by any of the parties; therefore, the procedure may end without an agreement being reached between the parties. If that is the case, it is most likely that the authorities will issue an assessment regarding all the omissions discovered during the review process.
As of 2022, mediation processes before Prodecon are limited to a 12-month period; if such term is exceeded without an agreement being reached, the process will be closed and the audit process will continue.
If an agreement is reached as a result of the mediation process, the potential contingency may be reduced, as both parties agree that the facts have a different nature than that attributed to them by the authorities, but they also have different effects than those reflected by the taxpayer on its tax return.
Surcharges shall be reduced in the same proportion as the potential contingency, as they are an accessory to the principal amount.
Penalties will be cancelled in full if it is the first time that the taxpayer has entered into a conclusive agreement. In subsequent cases, penalties should be applied and reduced according to the applicable laws.
Taxpayers are entitled to make a ruling request before the tax authorities regarding the tax effects of a specific transaction, a set of related transactions or a complete corporate restructure. The only condition is that the petition has to address actual and concrete situations, and the taxpayer has to propose the tax treatment that it considers to be appropriate.
The response to the petition is mandatory for the tax authorities if the ruling supports the position proposed by the taxpayer, which may lead to any dispute being avoided.
On the contrary, if the resolution on the ruling request does not endorse the criteria proposed by the taxpayer, it is not mandatory on the latter. Nevertheless, it may raise a flag to the authorities to audit the transactions discussed in the ruling request.
There is no limitation regarding the type of controversy, or any threshold with regard to the value of the claim or possible assessment, about which a taxpayer may request a conclusive agreement before Prodecon.
Taxpayers have the right to make a petition in this sense before the authorities issue the assessment. Therefore, the only limitation is time, as the taxpayer has a 20 business day term to file its petition for a settlement, from the date the observations letter is notified.
Prodecon has a 20-day term after the authorities submit their response in which to call for a meeting with the parties in order to sign the conclusive agreement. However, in practice, Prodecon procures the execution of as many working sessions as needed (within a prudent basis), in order to reach an agreement.
The parties have a 12-month period to reach an agreement, or the procedure will be closed, and the audit process will continue its path.
If both parties reach an agreement and proceed with the signing of a settlement, the terms of that settlement cannot be challenged before the courts. The only exception is when the authorities discover that the facts the agreement is based on are untrue or were simulated, in which case the complete agreement may be challenged.
If the agreement is only partial, authorities may issue an assessment regarding the issues for which there was no consensus between the parties. These issues may be challenged through the regular procedures described in 3. Administrative Litigation and 4. Judicial Litigation: First Instance.
There are no strict rules regarding the number of mediators and their appointment, as they are Prodecon officers who work full time as public servants at said agency, and are appointed according to the corresponding administrative rules.
The precedence of previous settlements does not necessarily have an influence on the result of a concrete mediation process; the precedence of jurisprudence may have an impact on the qualification of facts and their tax effects, with the same importance as in any other legal procedures regarding a controversy between a taxpayer and the authorities.
Agreements stated at the settlement must be based on strict law; nevertheless, in order to apply those criteria, the parties and the mediator tend to give preference to the substance of the transactions over the form, with the provision that there is sufficient documentary and technical support for the conclusions reached by the parties.
Limitations on ADR
It is important to have in mind that, as of 2021, taxpayers are not entitled to initiate ADR in those cases in which the controversy consists in:
Transfer pricing cases are settled according to the exact same procedure and rules as used for other tax disputes. It is important that the parties provide the technical elements that support their positions and the agreements they reach in order to determine a certain valuation of transactions between related parties.
In fact, with regard to transfer pricing issues, mediation has become the preferred option for taxpayers to resolve a controversy before entering into the litigation process.
Regarding indirect methods, there are specific rules that establish legal presumptions and ADR mechanisms that may be a useful tool to settle disputes. There is an additional path to demonstrate, in a collaborative manner, the origin of deemed income before entering into a litigation process in which the burden of proof lies with the taxpayer. Nevertheless, ADR has not become a significant mechanism through which to resolve controversies regarding potential contingencies derived from the use of indirect methods.
In Mexican legislation, there are only two types of liability for taxpayers related to tax payment omissions: administrative (as explained in previous sections) and criminal.
There are other administrative infringements that correspond to defaults of formal obligations; as a rule, the penalty for administrative infringements is a monetary fine.
Administrative infringements are regularly determined by the authorities during the same audit process as tax assessments and, accordingly, are challenged with the same legal remedies (unless the taxpayer chooses the substance trial).
It is important to keep in mind that, if the authorities issue a tax assessment against a specific taxpayer, this does not automatically lead to a criminal procedure. In general terms, although there are concrete legal provisions, criminal offences occur in cases where the taxpayer commits fraud by misleading the tax authorities, simulates transactions in order to avoid any tax consequences or issues artificial invoices.
If tax authorities discover a fact or transaction that may indicate a criminal offence, they can notify the federal prosecutor for tax matters (Procuraduría Fiscal de la Federación) so that they can make all the necessary investigations. If that special prosecutor finds merit in the case, then they could ask the federal prosecutor (Fiscalía General de la República) to initiate the criminal procedure stated according to criminal law; the tax authorities will act as the offended party.
A significant reform, in force as of 2020, ensures that tax fraud and the issuance of artificial invoices are considered as organised crime, and therefore require preventative prison sentences for the defendant, until the conclusion of the criminal trial.
However, in November 20222, the Mexican Supreme Court of Justice declared, in a mandatory precedent, that the legal provisions that consider tax fraud to be organised crime and the requirement for a preventative prison sentence for a defendant accused of such felonies are unconstitutional. The precedent has not yet been published but when it is the legal provisions will be annulled.
Administrative and criminal files are related, as the former may be evidence to the public prosecutor of the latter. Nonetheless, both processes may be carried out in parallel, as the criminal procedure does not have to be suspended while the Tax Courts issue their ruling regarding a tax assessment.
Additionally, the definitive ruling of one file does not determine the result of the other. As several precedents of federal courts have established, the reason for this relates to the burden of proof: at the administrative level, the taxpayer is obliged to demonstrate that the assessment has no legal grounds; while at the criminal level, the public prosecutor has to demonstrate that the defendant was involved in conduct that is described as a criminal offence.
As mentioned in 7.1 Interaction of Tax Assessments With Tax Infringements, administrative infringement processes are the same as those to determine and challenge tax assessments.
Criminal cases are initiated when tax authorities discover that the taxpayer has been involved in an act that is described as a crime regarding the applicable laws – ie, tax fraud, the simulation of transactions or the issuance of artificial invoices. Administrative processes may evolve to a criminal case only in such cases.
It is important to mention that this firm does not litigate criminal cases, so its expertise regarding the criminal tax offences is limited to general knowledge of the criminal process and its stages.
If the tax authorities discover that the taxpayer has been involved in an act that may indicate a possible crime, they are entitled to make the formal accusation before the federal prosecutor for tax matters, as mentioned in 7.1 Interaction of Tax Assessments With Tax Infringements.
This special prosecutor will, in turn, begin the investigation phase, where they will gather all the evidence needed to determine whether or not the taxpayer committed a criminal offence; if the prosecutor finds such evidence, they have to turn it over to the federal prosecutor.
If the conclusion is that there is enough evidence to implicate the taxpayer, the public prosecutor will formulate the formal accusation before the courts in order to proceed to criminal trial.
In those cases in which the omitted contributions or the amount of the artificial invoices do not exceed a threshold equivalent to USD400,000, prior to the initiation of the trial, there is the possibility for the victim – in this case, the tax authorities – and the defendant to arrive at an alternative resolution before the court in order to repair the damage caused by the taxpayer.
If there is no agreement between the parties, or the threshold previously mentioned is exceeded, the formal trial will take place according to the rules established in the National Criminal Procedures Code, which is an oral proceeding, where the prosecutor and the defendant will lay out their legal arguments and provide the corresponding evidence to support their positions.
The criminal judge will issue their resolution, whereby they will declare whether or not the defendant is guilty of the offence alleged by the prosecutor.
The courts that may hear criminal tax cases are the federal criminal courts, which may also hear any other kind of criminal case; there are no criminal courts specialised in tax offences.
Criminal courts that decide tax felonies are totally different from those that rule on the legality of the tax assessment.
If the taxpayer covers the unpaid taxes, plus surcharges and penalties, the tax authorities may request that the public prosecutor or the criminal court dismiss the case; this is a discretionary action that may be or may not be executed.
Additionally, if the taxpayer restitutes the unpaid amount during the process, the penalty may be reduced by 50%.
Finally, if the taxpayer pays the omitted taxes before the authorities discover the omission, the tax authorities will not execute any action before the public prosecutor.
As described in 7.4 Stages of Administrative Processes and Criminal Cases, there is the possibility to enter into an agreement with the tax authorities to prevent a criminal trial; the only condition of entering into such an agreement is the approval of the tax authorities, as the victim, and the defendant.
In order to challenge a decision adopted by the court of first instance, the National Criminal Procedures Code establishes an appeal procedure that will be ruled by an Appellate Collegiate Court (Tribunal Colegiado de Apelación), led by a federal magistrate. The resolution of this Court may be challenged through a direct constitutional injunction (juicio de amparo directo).
As a general rule, transactions challenged by the tax authorities under the GAAR, specific anti-avoidance rules (SAAR), transfer pricing rules or other anti-avoidance rules do not give rise to criminal cases. The reason is that these rules are too technical for a public prosecutor to demonstrate that the taxpayer participated in any fraud or simulation, as the burden of proof for criminal cases lies with the authorities.
Authorities tend to focus on the tax assessment procedures, unless there are very strong elements that may lead to a criminal case, or the issue acquires public relevance.
Nevertheless, authorities are expected to focus, from a criminal point of view, on prosecuting companies or taxpayers that are deemed to have issued artificial invoices, as this practice is now recognised as a form of organised crime.
If a double taxation situation occurs due to an additional tax assessment or tax adjustment in a cross-border transaction, the most common path to challenge the corresponding ruling is domestic litigation and/or the ADR mechanisms described in previous sections.
Also, mutual agreement procedures (MAPs) under double tax treaties signed by Mexico are a feasible way to obtain the nullity of the assessment.
A MAP is much less common but both procedures can be triggered by the taxpayer; if a MAP is filed before a foreign tax agency, the domestic litigation process will be suspended.
The Multilateral Instrument (MLI) was approved by the Mexican Senate during 2022; therefore, it is part of Mexican legislation.
Mexican jurisprudence has not addressed the issue of whether the GAAR or SAAR apply in cross-border transactions covered by bilateral tax treaties.
Nevertheless, authorities have applied a SAAR to such situations, usually overlooking the provisions stated in the applicable double taxation treaties signed by Mexico.
The new GAAR, in force as of 2020, does not limit its application to either domestic or cross-border transactions, even those covered by tax treaties; therefore, in a litigation process, whether the specific transaction is covered by a treaty benefit that has been overlooked by the authorities in its application of the GAAR should be considered.
As mentioned in 8.1 Mechanisms to Deal With Double Taxation, the MLI has not been approved by the Mexican Senate; therefore, it is not yet mandatory for Mexican authorities nor taxpayers.
Regarding the principal purpose test (PPT) and the amendment of the double taxation treaty (DTT) preamble, it is important to mention that Mexican authorities, when auditing cross-border situations in which the parties have applied a treaty benefit, regularly demand that the taxpayer demonstrate that the beneficial owner of the revenue is a resident of the other contracting state, in order to avoid treaty abuse.
The MLI provisions will grant additional instruments in order to prevent BEPS through structures and transactions that have the sole purpose of treaty-shopping.
As a rule, and in accordance with Mexican transfer pricing rules, resolutions issued by the authorities regarding transfer pricing adjustments that involve cross-border transactions focus on the determination of income and deductions of the Mexican resident taxpayer. Therefore, litigation against said assessments is regularly carried out before the Tax Court.
Additionally, transfer pricing adjustments can be challenged through the MAP foreseen in DTTs signed by Mexico.
Advance pricing agreements (APAs) are established in Mexican legislation and are a useful mechanism to avoid or mitigate controversies in transfer pricing matters, as taxpayers and authorities achieve a consensus regarding the methodology implemented by the former in controlled transactions.
The result of the procedure carried out by the parties is a ruling that will be in force in the fiscal year in which it was issued, in the previous year and in the following three years.
The APA can derive from a direct negotiation between the taxpayer and Mexican authorities, but also from an arrangement with foreign tax agencies of countries that have signed a DTT with Mexico.
The procedure is not expressly regulated by Mexican law, but it takes the path of a regular administrative procedure: the taxpayer shall file its petition before the tax authority, submitting the documentary, technical and legal evidence that supports its position. The authority may request additional information and documentation; there is the possibility of having working sessions in order to achieve an agreement and the notification of the corresponding ruling.
As a rule, cross-border situations that relate to transfer pricing generate more litigation. In order to mitigate such litigation, many taxpayers have chosen to enter into a conclusive agreement procedure before Prodecon, as described in 6. Alternative Dispute Resolution (ADR) Mechanisms, in order to achieve a settlement with the authorities.

Mexico did not opt for mandatory binding arbitration, according to Article 18 of the MLI.
The probable reason for this is that the Mexican government and Mexican tax authorities do not want third parties to decide whether or not they are entitled to collect a specific amount of taxes.
None of the relevant DTTs signed by Mexico has an arbitration clause.
Mexico has not opted for mandatory binding arbitration, either in terms of the MLI or in any of the relevant DTTs, none of which has an arbitration clause.
Neither baseball arbitration nor independent opinion procedures are possible with regard to international tax disputes in Mexico. See 10.2 Types of Matters That Can Be Submitted to Arbitration.
Mexico is not an EU state.
None of the recent international legal instruments regarding the settlement of tax disputes have been used yet in Mexico.
It is likely that Pillars One and Two will be introduced into Mexican legislation sometime in the future; nevertheless, it is also likely that Mexican authorities will harmonise the corresponding rules to foreign legislation.
Therefore, it is not expected that this will happen in the following two years.
Mexico has not opted for mandatory binding arbitration, either in terms of the MLI or in any of the relevant DTTs.
Mexico has not opted for mandatory binding arbitration, either in terms of the MLI or in any of the relevant DTTs.
Therefore, there are no domestic rules implementing the rulings issued by arbitration courts, in terms of the MLI.
Mexico has not opted for mandatory binding arbitration, either in terms of the MLI or in any of the relevant DTTs.
Therefore, there are no criteria adopted by taxpayers in order to hire independent professionals.
In the Mexican justice system, there are no fees for pursuing litigation at the administrative or judicial level regarding tax issues, nor any other matter (civil, criminal, labour). Therefore, taxpayers do not have to pay any fee before the tax authorities or the judicial courts to submit a claim and obtain a resolution.
The same criteria apply to the ADR mechanism of mediation before Prodecon, as it is a public agency funded within the federal budget.
Finally, taxpayers may request an indemnity from the tax authorities, when a tax assessment does not express its legal grounds or reasoning (fundamentación y motivación), or is issued against a mandatory precedent of the Supreme Court of Justice regarding the proper interpretation of the legal provisions applied.

According to the annual report of the Tax Court (the annual report), by the end of 2022 there were 79,896 cases pending at the Tax Court. The global monetary value of the cases handled by the Tax Court during 2022 was MXN573 billion (approximately USD3,942 billion).
The report does not disclose the number of cases attributed to each chamber of the Tax Court.
On the other hand, the annual report of the Supreme Court of Justice and the Federal Judicial Council provides information regarding the number of cases resolved by the former but does not disclose how many of them are related to tax issues, nor the number of cases ruled by the Federal Circuit Courts across the country.
According to the annual report, during 2022 a total number of 151,697 cases were initiated and 171,498 cases were terminated. However, the report does not disclose the number of the cases relating to different taxes or matters (as the Tax Court also has jurisdiction regarding social security, intellectual property, antitrust and other administrative issues), nor their monetary value.
The annual report only provides statistics about the party that succeeds in litigation, regarding the cases resolved by the Superior Chamber, which attends a limited number of cases, depending on the matter and the monetary threshold of the controversy.
Also, there are statistics regarding the number of verdicts issued by the Tax Court that were challenged and overruled by the Circuit Courts: during 2022, 148,878 verdicts were challenged (by the taxpayer or by the authorities) and 51,393 appeals were resolved, with the verdict of the Tax Court being revoked in 15,181 cases.
There are some strategic guidelines that taxpayers must consider in order to prevent a tax controversy or, when one is triggered, to defend themselves successfully.
First, the taxpayer should try to support its transactions with as much evidence as possible, such as contracts, invoices, payment receipts, communications with suppliers and services providers or any other material evidence that demonstrates the substance of the operations that generate tax effects.
Additionally, documentary evidence has to provide full proof of its date of issuance, in order to support the effects and substance of an agreement or transaction, according to the new precedent of the Supreme Court of Justice.
According to this precedent, a document will provide certainty of its date, by its ratification before a public notary or registration before a public registry. Nevertheless, there has been broad discussion among practitioners around other means to provide proof of this matter; therefore, legal advice on this issue is critical for taxpayers.
When an audit is initiated, the taxpayer should provide the tax authorities with all the evidence that supports the nature, substance and effects of the transactions that are being questioned by the auditors. Not disclosing information to the authorities is not a reasonable strategy, as evidence that is not provided to the auditor will not be accepted by the courts.
What the auditors must understand
Additionally, if auditors do not understand or are not convinced of the nature of the business, the business reasons for any transaction or restructuring, or the business model implemented by the company, they will likely issue an assessment without making a detailed and accurate analysis of the particular case.
It is crucial that the authorities understand the following:
Taxpayers will be in a better position to litigate before courts, or even at the level of the administrative claim, if the controversy deals with the interpretation of legal provisions, rather than the material support of the substance, nature and business reasons of the transactions, as the burden of proof lies on the taxpayer.
Even where the authorities determine an assessment based on a lack of material support, the more evidence submitted to the auditors, the better the position of the taxpayer to litigate or enter into a settlement process.
Cross-Border Transactions and Transfer Pricing
Regarding cross-border transactions, it is also advisable to disclose – as many times as expressly requested by the auditors – if the company did take any benefit from a tax treaty, and to provide the legal ground according to which the invoked treaty is applicable, at both the audit level and the litigation stages.
When it comes to transfer pricing controversies, the best strategy is to enter into a settlement process, in which the parties may achieve an agreement through the mediation of Prodecon.
Close Involvement of Legal Advisers
For these reasons, it is important for the legal adviser to be involved in every stage of a tax matter, from the very beginning of an audit, as the defence of the case is built through the entire review process, and not only at the litigation stages.

The Mexican economy has recently undergone significant structural changes with the aim of attracting foreign direct investment, which has become one of the country’s most important macroeconomic pillars. This investment strategy is evinced in multiple bilateral and multilateral agreements in various areas, including environmental and tax matters. Based on the above and as a guide to business decision-making in Mexico, this article will address two relevant aspects of the legal landscape in Mexico from a tax perspective: environmental taxes and recent judicial decisions.
As a matter of principle, it should be noted that Mexico has joined international efforts to transition to clean energy and protect the environment. To achieve this objective, Mexican lawmakers have implemented, in the legislation of several states of the Mexican Republic, so-called environmental taxes that, although theoretically pursuing a legitimate and valid purpose, in practice violate fundamental principles of justice in tax matters. It is clear that these environmental taxes have become an effective means of raising revenue, perhaps more important to the state than their environmental effect.
Another recent development to consider is the current position of the Mexican judiciary, which has recently issued several – in the authors’ opinion – unfortunate precedents that, far from providing legal certainty to taxpayers, have become a latent sign of the current parlous state of the rule of law in the country.
Offset VAT Is Not Creditable
In terms of the VAT Law, taxpayers who sell goods, render services, and/or grant the temporary use or enjoyment of goods, in Mexico, are obliged to pay the VAT. These taxpayers are known as “de jure taxpayers” since they trigger the tax by performing the taxed activities under Article 1 of the VAT Law.
However, the de jure taxpayers must charge such VAT to the person who receives the goods, the services, and/or the temporary use or enjoyment of goods. This person is known as the “de facto taxpayer”, since they actually pay the VAT.
According to the provisions of the VAT Law, the “payment” of the price for the above-mentioned activities triggers the de jure taxpayer’s obligation to pay the VAT to the Treasury. For this purpose, VAT Law provisions establish that any kind of extinction of the obligation (including offset) in which the de jure taxpayers consider satisfied their interest, will be deemed as “payment.”
On the other hand, VAT Law permits de facto taxpayers to credit the VAT paid to the de jure taxpayers, among other requirements, in the month when they pay the price and the corresponding VAT.
Considering the above, it has been common practice in Mexico for de facto taxpayers to “pay” the price of the goods, services, and/or temporary use of goods, including the corresponding VAT, via offset, to de jure taxpayers. In these cases, the de facto taxpayers have considered such offset VAT as creditable against their own caused tax, as de jure taxpayers.
Under this VAT Law interpretation (considering the offset VAT to be creditable), several taxpayers have reduced the amount of their due VAT before the Treasury and, in some cases, even obtained balances in favour refunds.
Notwithstanding this, on 15 March 2023, the Second Chamber of the Mexican Supreme Court of Justice (SCJ) approved a precedent resolving a contradictory precedent, under the number 413/2022. In its final judgement, the Second Chamber ruled that the offset VAT is not creditable.
According to this precedent, the de facto taxpayer can offset the price of the goods, services and/or temporary use of goods, but it has to pay the corresponding VAT in cash; otherwise, the offset VAT will not be creditable. This precedent is already mandatory and cannot be appealed.
Due to the above-mentioned precedent, the tax authority could initiate tax audits upon taxpayers who have offset VAT, to determine them a tax contingency, as well as denying refunds under this argument.
In addition, the tax authorities could send official communication to taxpayers who have offset VAT to correct their tax situation. Such communication has been used as a quick and effective collection mechanism that does not imply enforcement and collection powers.
Taxpayers should also be aware of the possibility that the tax authority may question previous refunds of VAT balances in favour, authorised without prior audit, that have resulted from considering creditable offset VAT.
This precedent will have a considerable impact on the conduct of certain transactions, and, in some cases, it will be necessary to modify day-to-day transactions so that taxpayers offset only the price and pay the corresponding VAT in cash.
Finally, taxpayers should analyse the impact of this precedent on their future and previous transactions, considering the tax implications that VAT offsets could trigger.
The Mexican Income Tax Law (ITL) establishes, in its Title II, Chapter II, Section I, the list of general deductions that can be applied by legal entities considered residents in Mexico for tax purposes, as well as some requirements for such purposes.
Among those requirements, the aforementioned provisions establish that, notwithstanding the fact that the income tax regime for legal entities is governed under accrual rules, in the case of expenses with individuals and with some specific entities, they can only deduct those expenditures until they in fact pay them.
On the other hand, the ITL provides, in its Title II, Chapter II, Section II, that taxpayers can deduct investments (fixed assets, deferred expenses and charges, and expenditures paid in pre-operating periods), under specific rules, up to a maximum percentage each year, during an estimated utility period.
Under the interpretation of those ITL provisions, it has been a common practice in Mexico that legal entities deduct their investments, fulfilling the requirements stated in the above-mentioned Section II, whether or not they have in fact paid such investments.
However, on 30 November 2022, in a ruling on the Direct Amparo under Review number 2163/2022, the Second Chamber of the SCJ held that, for income tax purposes, entities can only deduct their investments until they in fact pay them.
The Second Chamber of the SCJ reached this conclusion based on an interpretation of the above-mentioned Section II provisions. Specifically, the Second Chamber of the SCJ determined that Article 31 of the ITL does establish the payment of the investments as a requirement for the beginning of its deduction.
This, in the authors’ opinion, is as an unfortunate interpretation of Article 31 of the ITL, since it does not expressly provide as a requirement for the deduction of investments, that taxpayers must pay them. In addition, the Second Chamber of the SCJ lost sight of two particularly relevant principles:
Regarding the second principle just mentioned, there is no doubt that provisions that establish the permitted deductions for income tax purposes, and their requirements, must be strictly interpreted - even though provision states applied - since they directly affect one of the essential elements necessary to calculate the referred tax. This means that if the ITL provisions, in its Title II, Chapter II, Section II, do not expressly mention that entities must pay their investments to deduct them, said deduction should be interpreted and applied under the accrual rules that govern the income tax regime for entities.
Unfortunately, the ruling of the Second Chamber of the SCJ is mandatory for every court in Mexico (except for the First Chamber and the Plenary of the SCJ), under the Amparo Law provisions.
Consequently, it is highly probable that the tax authorities will initiate audits in order to review if taxpayers who have deducted investments began their deductions once they paid them, or if they did it under the rules of accrual. In this last case, tax authorities may determine a tax contingency under this interpretation of Article 31 of the ITL.
Although the authors do not share this interpretation, it is still recommended that entities that have deducted investments, or that are going to do so, take it into consideration.
In recent years, local congresses have more frequently resorted to so-called “environmental” or “green” taxes; the collection of such taxes has become an important source of local revenue, alongside the payroll tax. Some of the states that have adopted such taxes, are Baja California, Campeche, Coahuila, Estado de México, Nuevo León, Oaxaca, Querétaro, Quintana Roo, Yucatán, and Zacatecas.
Each state has its own set of unique regulations and rules for such taxes. For example, Estado de México approved, as of 2022, an emissions tax that does not subject to tax those emissions whose regulatory source is the federal government.
The State of Guanajuato adopted a similar emissions tax in effect as of 2023; however, the CO₂ bio-equivalencies of certain gases subject to tax, differ from those established in the 2015 federal regulations (the “acuerdo”) relating to gases that trigger greenhouse effects.
Both peculiarities raise the question of whether the alleged purpose of the tax – to counter greenhouse effects – is effectively met for such emissions taxes under a “reasonability test.” As a result, several taxpayers have challenged the local provisions, through Amparo claims.
The SCJ has issued several precedents in which it practically determined all the provisions regulating the green taxes raised in Zacatecas, which was the first state to adopt environmental taxes, to be constitutionally valid. This is on the grounds that they do not violate the principles of taxation (equity, proportionality and legality) and pursue a constitutional purpose.
Each state has different regulations and tax treatment rules. Unfortunately, too often the policies lack coherence and undermine efforts to reduce negative environmental impacts; instead, appearing to be for the sole purpose of raising taxes. Consequently, taxpayers have filed Indirect Amparo claims challenging the local regulations.
Although the Zacatecas precedents could be taken as a basis for resolving environmental tax suits filed in other states, each tax has particularities to which the SCJ’s precedents are not applicable. As a result, their constitutionality is still up for debate.
Double Taxation Treaties
The authors consider that the Sections of the Higher Chamber of the Federal Tax on Administrative Matters hold dissenting opinions on how to resolve tax refund procedures that involve payments to foreign residents.
The Second Section ruled on a case in 2022 concerning payments made by a Mexican tax resident to its German counterpart, in consideration for technical services. The Mexican entity applied a 10% withholding tax on “royalties” payments, pursuant to the Mexico-Germany Double Taxation Treaty (DTT).
Afterwards, the Mexican entity requested a refund arguing no withholding tax was applicable, on the basis that such payments should be treated as business profits. The Mexican tax authorities denied the claim since the German counterpart deducted the tax withheld from its corporate tax basis, and thus, the refund of the withholding tax would give rise to an undue “double” benefit, as argued by the Court.
In the Second Section’s view, the deduction by the German counterpart “forbade” the Mexican entity from requesting the refund of the tax withheld, since this would have resulted in double non-taxation, which conflicts with one of the treaty’s purposes. The Court considered that if the refund was authorised, the German counterpart was bound to increase its tax base; however, it concluded that the basis of the refund request cannot legally depend on “future and conditional” acts, and thus, ruled to uphold the denial of the refund.
On the other hand, the First Section of the Higher Chamber ruled on a similar case in 2022 and took an opposing view. This Section considered that no local provision (Article 22 of the Federal Tax Code) makes the authorisation of a tax refund conditional on the amount requested not being deducted abroad.
Moreover, the Section, upon analysing a precedent from the SCJ, considered – without expressly stating so – that only when this deduction is made in Mexico (not abroad), can a potential argument exist to deny the refund request.
This, on the basis that a clear double benefit would arise from this deduction and refund requested, which, if authorised, would erode the Mexican tax base.
Therefore, while the First Section regards, when resolving the authorisation of a tax refund, the amount deducted abroad as irrelevant for Mexican tax purposes, the Second Section considers that this tax effect can be validly used as an argument to deny the request. The First Section’s ruling is, in the authors’ opinion, more aligned with Mexico’s current legal framework and existing court precedents.
These opposing views do not provide taxpayers with the necessary legal certainty regarding the prevailing criteria when ruling upon refund requests concerning payments made abroad.
