International Tax 2026 Comparisons

Finland’s international tax position is determined primarily by statute law (notably the Act on Income Tax), complemented by Finnish Tax Administration (Vero) guidance and case law. Treaty application is supported in practice through published treaty texts and synthesised treaty texts (including versions synthesised by the Multilateral Instrument (MLI)) that are made available for users.

Finland maintains an extensive bilateral income tax treaty network.

Finland’s domestic rules determine tax liability and taxable income as a starting point, while tax treaties can limit Finland’s taxing rights in cross-border situations. The domestic residency and source rules have priority over treaty-based outcomes for cross-border payments and residency tie-break considerations. In practice, treaty application requires checking (i) whether the taxpayer is treated as resident or non-resident under domestic rules, and (ii) whether a treaty modifies the result, including through MLI modifications where applicable.

From a practical application perspective, treaty analysis typically includes verifying whether the relevant treaty text is an MLI‑synthesised version and whether treaty amendments affect core items such as allocations of taxing rights or withholding tax rates, as emphasised in Finnish Tax Administration treaty guidance. The same guidance also underlines that the MLI’s effects are applied treaty‑by‑treaty and must be checked for each treaty partner.

Finland’s treaties and treaty practice generally follow the structure and concepts of the OECD Model, including the standard treaty architecture (eg, Articles on residence, permanent establishment, associated enterprises, the Mutual Agreement Procedure (MAP) and exchange of information), which also supports consistency in interpreting treaty concepts in practice. This OECD alignment is particularly visible in transfer pricing‑related treaty interpretation, where OECD‑based concepts are used as an interpretative reference point when applying treaty provisions on profit attribution and related concepts.

Finland ratified the MLI on 13 February 2019 (parliamentary ratification), and the MLI entered into force in Finland on 1 June 2019. Finland’s ratification decree and reservations/notifications are referenced in Finnish official publications, and MLI effects apply treaty-by-treaty depending on the other jurisdiction’s status.

Finland distinguishes between resident and non-resident tax liability, which determines whether Finland taxes worldwide income (residents) or only Finnish-source income (non-residents).

The Finnish Tax Administration’s residency guidance frames this resident/non‑resident distinction as the key determinant of worldwide versus source‑based taxation for individuals, and also links the domestic classification to tax treaty residence concepts where a treaty applies. In cross‑border cases, this means that the domestic classification is the starting point, but treaty residence tests can become relevant where dual residence arises.

The same guidance emphasises that domestic residence/non‑residence is assessed under the Income Tax Act and that treaty residence analysis is relevant primarily where the treaty’s residence concept must be applied alongside domestic status (eg, in dual‑residence situations).

An individual is treated as Finnish tax resident if they have their permanent home in Finland or if they stay in Finland for a continuous period of more than six months. Finnish citizens who move abroad are generally subject to the three-year rule, under which they remain Finnish tax resident during the year of departure and the following three tax years unless they can demonstrate they no longer have “essential ties” to Finland. “Essential ties” refers typically to maintaining a permanent home in Finland, a spouse living in Finland, ownership of Finnish real property (beyond a summer cottage) and certain ongoing economic or work connections.

The Finnish Tax Administration’s dedicated guidance on the three‑year rule highlights that changing to non‑resident status during the three‑year period generally requires a specific request and evidence that economic and social ties have ceased; it also provides indicative examples of ties that often keep residency in place, such as ongoing Finnish social security coverage or continuing to run a business or perform work in Finland.

Finnish tax residents are, as a starting point, taxed on worldwide income, but treaty rules and domestic mechanisms can mitigate double taxation. In cross-border contexts, Finland’s approach is to determine domestic liability first and then apply treaty and procedural mechanisms (including treaty benefits where conditions are met).

Finnish Tax Administration residency guidance expressly describes residents as having “unlimited” tax liability in Finland (worldwide income), while also noting that treaty residence rules may become relevant where the treaty requires determining residence under treaty criteria in addition to domestic law.

Non-resident individuals are taxed in Finland on Finnish-source income, commonly through tax at source. Finnish Tax Administration guidance on cross-border dividends/interest/royalties explains that non-resident status limits Finland’s taxing rights and that treaty benefits may reduce Finnish tax at source where eligibility can be demonstrated.

In practice, treaty relief at source generally requires that the income beneficiary is identified and that eligibility for treaty benefits is verified using reasonable measures (eg, a certificate of residence or an investor self‑declaration in the relevant withholding tax context).

A company is resident in Finland if it is incorporated/registered in Finland. In addition, foreign corporate entities may be treated as Finnish resident taxpayers if their place of effective management is in Finland.

Finnish Tax Administration guidance explains that “place of effective management” refers to where the corporate entity’s board or other decision‑making body makes top‑level decisions on daily management, taking into account the broader facts of the organisation and operations. It also distinguishes this resident‑taxpayer concept from situations where a “place of management” may instead create a Finnish permanent establishment for a non‑resident foreign company.

For income tax purposes, the concept of permanent establishment (PE) stems from the tax treaties and is aligned with the OECD Model; ie, a PE is defined as a fixed place of business through which the business of an enterprise is wholly or partly carried out. Potential variations in certain details (such as time thresholds) are treaty-specific.

Finnish Tax Administration guidance for foreign companies describes typical PE examples consistent with treaty practice, including places such as a place of management, branch, factory or workshop, and notes that construction/installation projects may constitute a PE where the relevant treaty time threshold is exceeded. The same guidance also notes that a fixed place of business requires a distinct geographic location and a degree of permanence, and that in some circumstances a PE may also be linked to a dependent agent, depending on the facts and applicable treaty provisions.

Income from immovable property located in Finland (eg, rental income, certain usage compensations) is taxable in Finland regardless of the taxpayer’s residence. This follows both Finnish domestic law and Finland’s tax treaties, which allocate taxing rights over immovable property income to the state where the property is located.

Rental income from immovable property is treated as capital income for residents and non-residents. Capital income is taxed at:

• 30% on the first EUR30,000, and
• 34% on the excess.

Rental income from property located outside Finland is also taxable in Finland for residents, subject to double tax relief under the applicable tax treaty (typically credit or exemption methods).

In Finland, corporate business profits are taxed at a flat 20% corporate income tax rate, with resident companies taxed on worldwide income and non-resident companies taxed only on profits attributable to a Finnish permanent establishment.

Partnerships are transparent for tax purposes, with profits taxed at partner level.

Self-employed individuals are taxed under the individual income tax system, where business profits are split into capital and earned income, while non-residents are taxed only if they have a permanent establishment or fixed base in Finland.

Tax treaties mainly limit Finland’s taxing rights for foreign businesses without a Finnish presence.

For payments from Finland to non-residents, the payer must generally withhold tax at source at 20% where the beneficiary is identified as a corporate entity, 30% where the beneficiary is identified but its status is unclear, and 35% where required beneficiary information is missing (notably nominee-registered shares). Treaty benefits or other legal grounds can reduce the rate where eligibility is documented.

In addition to rate mechanics, Finnish practice places strong emphasis on beneficial-owner identification and treaty‑eligibility verification as conditions for granting treaty relief at source, particularly for dividends on nominee‑registered shares. Treaty benefits are granted only where the beneficiary is identified and eligibility has been verified.

In Finland, capital gains arise from the disposal of assets, such as shares, real estate, business interests or other property. For individuals, capital gains are taxed as capital income (taxable at the standard capital income tax rate of 30% or 34%). For companies, capital gains are generally treated as part of taxable business income (taxable at the 20% corporate income tax rate), unless a specific exemption applies.

In cross-border contexts, treaty provisions (eg, Article 13 of the OECD Model structure) can affect the allocation of taxing rights, especially for share disposals linked to immovable property or permanent establishment assets, depending on the treaty wording.

Finland distinguishes between resident and non-resident taxpayers:

• Residents (permanent home in Finland or stay exceeding six months) are subject to unlimited tax liability and are taxed on their worldwide employment income.
• Non-residents (stay of six months or less) are taxed in Finland only on Finnish-source employment income.

Individuals working in Finland for six months or less are generally treated as non-residents. Their employment income may be taxed in Finland depending on the circumstances.

• Default taxation: 35% final withholding tax on gross wages (after a standard deduction of EUR510 per month/EUR17 per day).
• Optional progressive taxation: Non-residents from treaty countries may opt for progressive taxation instead of the flat 35%.

Even for short stays, Finland may tax employment income if:

• the employer has a permanent establishment (PE) in Finland;
• the individual is a leased employee;
• the individual is a performing artist or athlete; or
• a tax treaty allocates taxing rights to Finland.

Finland does not have separate domestic legislation specifically for “remote work PEs”. Instead, PE risk is assessed under the Finnish domestic law and tax treaties following OECD Model principles. Remote work performed physically in Finland is generally treated as Finnish-source employment income, regardless of employer location, unless a tax treaty restricts Finland’s taxing rights. Remote work performed outside Finland by a Finnish resident may qualify under the six-month rule, but only if the statutory conditions are met.

There are no other specific types of income subject to special taxation rules in Finland.

As of April 2026, Finland has not formally implemented Amount B, nor has it announced binding administrative guidance or legislation adopting the OECD Amount B simplified and streamlined approach. Finland remains aligned with the OECD Transfer Pricing Guidelines generally, but Amount B is optional by design, and there is no public statement from the Finnish Ministry of Finance or the Finnish Tax Administration confirming adoption, planned adoption or local deviations.

In the absence of a Finland-specific Amount B implementation, distributors and baseline marketing/distribution activities remain subject to Finland’s ordinary transfer pricing framework, including the requirement to prepare transfer pricing documentation under the Finnish rules (documentation rules are unchanged even after the 2022 update to the transfer pricing adjustment provision). As a result, any simplification for baseline distribution would, in practice, need to be reflected through explicit domestic guidance or accepted administrative practice to have operational effect.

Finland supports Pillar One Amount A at the OECD/Inclusive Framework level but has not yet implemented it domestically. Finland considers the practical impact on Finnish enterprises to be limited, supports implementation only via the Multilateral Convention (MLC), and has taken no unilateral action while the MLC remains unsigned and unratified.

Finland has participated in OECD-level discussion on the taxation challenges of digitalisation and has supported the need for an international solution led through the OECD process, including the view that the digital economy should not and cannot be ring-fenced. This broader policy context aligns with Finland’s preference for multilateral implementation rather than unilateral domestic action in this area. The Finnish Tax Administration commentary further notes that implementing Amount A would require a multilateral convention that is not yet open to signature, and therefore Amount A does not, for the time being, require action by Finnish enterprises.

Finland has implemented the OECD/G20 global minimum tax under Pillar Two.

The rules apply to accounting periods beginning on or after 31 December 2023 (ie, from tax year 2024 for calendar‑year groups). The Undertaxed Profits Rule generally applies to accounting periods beginning on or after 31 December 2024 (ie, from tax year 2025).

Finland has also adopted a Qualified Domestic Minimum Top‑up Tax applying from periods beginning on or after 31 December 2023.

The minimum tax returns can be submitted as of 30 January 2026.

Finland’s implementation of the global minimum tax under Pillar Two closely follows the OECD/GloBE framework and the EU Minimum Tax Directive, with no material policy‑driven deviations. Where differences exist, they are technical, EU‑driven or administrative, rather than substantive departures from the OECD Model Rules.

Finland’s policy discussion has historically emphasised an OECD-based global solution to digitalisation-related tax challenges, including the view that the digital economy should not be ring-fenced. This reinforces the point that Finland has not introduced a separate domestic digital services tax and has instead focused on multilateral approaches to address digitalisation-driven issues.

In Finland, “tax fraud” vs “tax evasion” is generally covered by the tax crime provisions in the Finnish Criminal Code (Rikoslaki) Chapter 29. The core offence is veropetos (tax fraud). Its key elements focus on deceptive conduct aimed at producing an incorrect tax outcome (or attempting to do so).

Legal criteria (core elements) for veropetos include that a person (i) gives the authority false information relevant to assessment, (ii) conceals a relevant fact in a return/notice, (iii) fails a tax‑related duty with the intent to avoid tax, or (iv) otherwise acts fraudulently, and thereby causes or attempts to cause tax not to be assessed or to be assessed too low, or to cause an undue refund. These are explicitly listed as alternative “modes of commission” in the veropetos provision.

Finland also has aggravated and petty forms. Aggravated tax fraud (törkeä veropetos) is characterised (in essence) by seeking substantial economic benefit and/or particularly planned conduct, plus an overall assessment of seriousness. This is relevant in cross‑border settings where structures are intentionally engineered to hide income, beneficial ownership or flows.

Finland combats tax fraud, evasion and avoidance through a combination of general and targeted anti-avoidance rules, information-reporting regimes and risk‑based tax control. A central tool is the general anti-avoidance rule (GAAR) in the Act on Assessment Procedure (VML), applied where arrangements are implemented primarily to obtain tax benefits contrary to the purpose of tax law; the Finnish Tax Administration has issued detailed guidance on the application of the GAAR (VML 28 §).

In cross-border contexts, specific anti-avoidance mechanisms include, among others: (i) CFC rules under the Finnish Controlled Foreign Company regime (Act 1217/1994) and related guidance, aimed at preventing the diversion of Finnish-taxable income to low-taxed foreign entities; (ii) interest limitation rules (EVL 18 a/18 b) restricting net interest deductions to address base erosion through excessive debt funding; and (iii) transfer pricing rules based on the arm’s length principle, including documentation obligations and reporting (eg, Form 78, CbC rules), used both for compliance and as a basis for audit selection and potential adjustments.

Finland also relies heavily on transparency and disclosure. DAC6 requires reporting of certain cross-border arrangements that meet hallmarks associated with aggressive tax planning, thereby enabling early detection and deterrence. In addition, Finland participates in automatic exchange of financial account information (FATCA, CRS and DAC2), which strengthens tax control and combats offshore evasion. Finally, Finland has implemented enhanced procedures in the withholding tax context (eg, for nominee-registered shares) that require identifying and verifying the dividend beneficiary before treaty benefits can be granted at source.

Finland does not rely on a stand‑alone domestic “blacklist” in the same way some jurisdictions do; however, for EU purposes, Finland references the EU list of non‑cooperative jurisdictions for tax purposes in areas such as DAC6 reporting. The Finnish Tax Administration explicitly notes that updates to the EU list should be taken into account when reporting arrangements under the DAC6 hallmark that refers to non‑cooperative jurisdictions.

Tax consequences in Finland that are clearly linked to “listed jurisdictions” are therefore most directly seen through reporting/monitoring effects (eg, DAC6 hallmark-driven reporting and increased transparency), rather than an automatic, Finland‑specific punitive tax rate solely triggered by a blacklist designation. Where cross-border payments are concerned, Finland’s system can also impose practical consequences where beneficiary identification is not properly established for treaty relief at source, requiring robust verification and documentation.

Finland uses extensive reporting and disclosure regimes to detect and prevent tax fraud, evasion and avoidance, especially in cross‑border situations.

Key regimes include:

• DAC6 (reportable cross-border arrangements): Intermediaries (service providers) or, in some cases, the relevant taxpayer must report qualifying cross-border arrangements that meet specified hallmarks. Reports must generally be filed within 30 days from the triggering event, and can be submitted via MyTax or Ilmoitin.fi (including XML/name-value formats).
• Country-by-country (CbC) reporting: Multinational groups meeting the threshold (generally EUR750 million consolidated revenue) are subject to CbC reporting and notification obligations. The Finnish Tax Administration provides detailed instructions and e-filing processes for both the CbC report and the notification of reporting entity.
• Transfer pricing documentation and annual disclosure: Taxpayers within scope must maintain transfer pricing documentation and submit annual disclosures (including Form 78 “Explanation of Transfer Prices” with the corporate income tax return where applicable), supporting risk assessment and audit selection.
• Automatic exchange of information (AEOI) – FATCA/CRS/DAC2: Finnish financial institutions must identify reportable account holders and file annual information returns. Finland then exchanges such information automatically with partner jurisdictions, which “enhances tax control and combats tax evasion”.
• Other third-party reporting regimes: Finland also applies structured third-party reporting frameworks (eg, platform operator reporting and other specified reporting duties) within the Act on Assessment Procedure framework. The Tax Administration has detailed guidance on penalty payments relating to failures to comply with specified third-party reporting obligations (including FATCA/CRS/DAC2, DAC6 and platform reporting).

In addition, Finland enables reporting of suspected non-compliance through an electronic channel, allowing the Tax Administration to receive tips (including anonymously) about suspected tax evasion.

The Finnish Tax Administration has broad powers to examine taxpayers’ compliance through administrative tools, primarily information requests and tax audits, supported by statutory audit rules and detailed administrative guidance.

Tax audits are a core tool of tax control. The legal provisions governing tax audits are set out in, among others, Section 14 of the Act on Assessment Procedure (and parallel rules for self‑assessed taxes, prepayments and car tax), and the Tax Administration has issued comprehensive guidance describing tax audit objectives and procedure.

During a tax audit, the taxpayer may be required to provide extensive material. Finnish secondary legislation governing the audit process (verotusmenettelyasetus) specifies that, in a tax audit, the taxpayer must present for inspection business-related material and property, including accounting records and supporting documents (eg, ledgers, vouchers), correspondence, notes and other accounting/management documentation, contracts and minutes, etc.

As regards unannounced visits and “raids/fiscal perquisitions”, Finland’s primary tax-control model is administrative auditing and information-gathering under tax procedure legislation. The Tax Administration guidance recognises that audits can be conducted simultaneously with other authorities’ measures, for example where a police pre-trial investigation is ongoing; in such cases the tax auditor acts under tax-law powers while criminal investigative powers lie with the competent criminal authorities.

The Finnish framework for administrative penalties relevant to cross-border transactions includes (i) tax increases and late-filing charges under tax procedure rules, and (ii) specific penalty payments for failures in international reporting and transfer pricing documentation. Administrative tax penalties are imposed and administered by the Finnish Tax Administration.

As a general matter in income taxation, taxpayers may be subject to administrative late fees and tax increases (veronkorotus) where returns or required information are late, incomplete or incorrect; the Tax Administration describes tax increases as calculated on a formula basis (eg, a percentage of the added income) in personal income tax contexts. More broadly, the statutory basis for tax increases in the Act on Assessment Procedure (VML) is reflected in case law applying VML 32 § (and related provisions).

For cross-border compliance specifically, Finland provides for administrative penalties tied to transfer pricing documentation and CbC reporting. Finland’s transfer pricing profile indicates that for non-compliance with documentation or CbC reporting requirements, the tax authorities may impose a penalty not exceeding EUR25,000, and such penalty may be imposed even if no transfer pricing adjustment is made.

In addition, failures to comply with certain international third‑party reporting obligations (including FATCA/CRS/DAC2, DAC6 and platform reporting) can trigger a penalty payment (laiminlyöntimaksu) under VML 22 a §; the Tax Administration has detailed guidance on the imposition of such penalties in relation to specified reporting obligations.

Tax fraud offences are criminalised under the Finnish Criminal Code (Chapter 29). In broad terms, tax fraud (veropetos) is punishable by a fine or imprisonment for up to two years, while aggravated tax fraud (törkeä veropetos) may lead to imprisonment typically in the range of four months up to four years, depending on the circumstances (eg, substantial benefit sought or particularly methodical conduct).

Finland follows a framework intended to prevent “double punishment” for the same conduct (ne bis in idem). The Finnish Tax Administration explains that tax increases can be comparable to criminal penalties, and that tax-related misconduct is therefore handled either administratively or through criminal proceedings, depending on the nature and severity of the case. Where a matter is to be handled as a crime case, the Tax Administration may issue a tax assessment decision but refrain from issuing a tax‑increase decision, and may file a crime report, after which the prosecutor may bring charges.

There is not an “automatic” referral for every irregularity; rather, the framework requires an authority decision on the appropriate track (administrative penalty vs criminal process) in light of ne bis in idem considerations. In practice, co-ordination is facilitated by the possibility to conduct a tax audit alongside other authorities’ actions, including situations where a police pre-trial investigation is ongoing.

Finland’s administrative co‑operation in tax matters is grounded in a combination of EU directives, international agreements/standards and bilateral tax treaties.

At an operational level, Finland participates in automatic exchange of information based on international commitments and instruments, including FATCA, the OECD CRS and the EU DAC2 framework. Finland also implements EU administrative co-operation measures such as DAC6, which provides for reporting and EU‑level exchange of information on reportable cross‑border arrangements.

For dispute resolution within the EU, Finland applies the national Act on International Tax Dispute Resolution Procedure (530/2019) and related decree, which transpose Council Directive (EU) 2017/1852 on EU tax dispute resolution mechanisms into Finnish law.

Finland exchanges information through multiple channels, including automatic exchange and structured reporting regimes. Finland participates in automatic exchange of information and receives information in return; this includes FATCA, CRS and DAC2, supported by annual reporting obligations for Finnish financial institutions. Additionally, DAC6 operates as an “early alert” mechanism in the EU, requiring reporting of certain arrangements and enabling exchange of the reported information among EU tax authorities.

Beyond the MAP and advance pricing agreements, Finland participates in (and has developed) additional collaborative and proactive tools aimed at increasing tax certainty and reducing disputes, particularly in transfer pricing. One example is Cross-Border Dialogue, which is a Finnish-initiated process designed to align preliminary ruling outcomes in more than one jurisdiction through administrative co-operation and information exchange channels.

Finland has an established MAP practice. In transfer pricing matters specifically, the MAP may be based on: (i) the MAP article in Finland’s income tax treaties (aligned with Article 25 of the OECD Model), (ii) the EU Arbitration Convention (90/436/EEC), or (iii) the EU tax dispute resolution mechanism under Directive 2017/1852 as implemented domestically. The domestic procedural framework is set out in the Act on International Tax Dispute Resolution Procedure (530/2019) and related decree.

The filing deadline for a MAP request depends on the relevant tax treaty or the applicable EU dispute resolution procedure. The time limit is usually three years from the first time the taxpayer learned that they had been taxed contrary to the treaty (eg, upon receiving a tax decision) or (for an EU dispute resolution procedure) three years from when the taxpayer first learned about the double taxation (eg, tax decision).

Mandatory binding arbitration is generally available in Finland in EU disputes within the scope of the EU dispute resolution framework. Finland has implemented the EU dispute resolution mechanism through the Act on International Dispute Resolution Procedure (530/2019), transposing Directive (EU) 2017/1852, which is designed to ensure effective resolution of disputes (including those leading to double taxation) and provides for dispute resolution mechanisms where the competent authorities do not reach agreement within the prescribed timeframes.

Finland recognises advance pricing agreements (APAs) as a dispute prevention tool in transfer pricing. There is no separate APA legislation; instead, Finland can conclude APAs with treaty partners and the APA process is based on the MAP in Finland’s tax treaties, which in turn is grounded in Article 25 of the OECD Model Tax Convention.

There are several tools available in Finland for obtaining tax certainty: pre-emptive discussion (ennakollinen keskustelu) as an early-stage dialogue resulting typically in a memo that supports reliance but is not appealable, advance rulings (ennakkoratkaisu) as a written binding decision on the applicant’s own taxation (subject to conditions and potential appeal), and cross-border dialogue as a multi-country advance process aimed at aligned national outcomes rather than a single inter-state agreement.

Furthermore, an enhanced customer co-operation programme (syvennetty asiakasyhteistyö), launched in Finland in 2016, is aimed at multinational enterprises and focused on reviewing tax strategy and risks with a more real-time, open dialogue to increase predictability and reduce disputes.
