Businesses in Ireland tend to incorporate in order to take advantage of the benefits of separate legal entity status and limitation of liability. Ireland enacted amended and consolidated company law legislation in 2014 (the Companies Acts 2014), which provides for the following forms of incorporated entity:

  • private company limited by shares (LTD);
  • designated activity company (DAC);
  • public limited company (PLC);
  • company limited by guarantee (CLG);
  • unlimited company; and
  • investment company.

The limited company has traditionally been the most popular form for incorporated trading business, and is likely to remain so. Companies involved in the issuance of listed debt securities are formed as DACs. Investment funds are incorporated as investment companies or as Irish Collective Asset Management Vehicles (ICAVs).

Entities with separate legal form are taxed separately.

In Ireland, partnerships and limited partnerships are treated as transparent for tax purposes. Partnerships are generally used for investment purposes and also by certain professional services firms (eg, accountants and solicitors). In addition, pension funds may make use of a particular form of tax-transparent investment fund called a common contractual fund (CCF).

A company that has its central management and control in Ireland is considered resident in Ireland, regardless of where it is incorporated. A company that is incorporated in Ireland is considered resident in Ireland, except where the company is regarded as not being resident in Ireland under a double taxation treaty between Ireland and another country.

The term “central management and control” is, in broad terms, directed at the highest level of control of the company. The Irish Revenue Commissioners (“Irish Revenue”) and the Irish courts emphasise the location of the meetings of the board of directors.

Ireland currently has two rates of corporation tax.

  • A 12.5% rate applies to the trading income of a company that carries on a trade in Ireland (including certain qualifying foreign dividends paid out of trading profits). There is no precise definition of what constitutes trade for this purpose but, broadly, where a company is carrying on an active business in Ireland on a regular or habitual basis and with a view to realising a profit, it should be considered to be trading for tax purposes.
  • A 25% rate applies in respect of passive or investment income, profits arising from a possession outside of Ireland (ie, foreign trade carried on wholly outside of Ireland) and profits of certain trades, such as dealing in or developing land and mineral exploration activities.

In October 2021, the Irish Minister for Finance announced that Ireland would sign up to the OECD's Inclusive Framework, which was intended to reform international tax rules in order to address the challenges arising from the digitalisation of the global economy. As part of its implementation, a new corporation tax rate of 15% will be introduced in Ireland for large groups – specifically, groups with an annual consolidated revenue in excess of EUR750 million.

The EU Directive on minimum taxation was published in the EU Official Journal on 22 December 2022. EU member states must bring into force the laws, regulations and administrative provisions necessary to comply with this Directive by 31 December 2023.

Separately, a 33% rate applies to capital gains. The same capital gains rates also apply to gains earned by individuals directly or through transparent entities.

Personal income is subject to tax at rates of up to 55%.

Corporation tax is imposed on the profits of a company (including both income and chargeable gains), wherever they arise, for the fiscal year or “accounting period” of the company. The accounting period cannot exceed 12 months.

The starting point for determining taxable profits is the profit of the company according to its statutory accounts, subject to any adjustments required by law. The more important items that are not deductible when calculating the tax-adjusted profits include the following:

  • any capital expenses;
  • any expenses not wholly or exclusively incurred for the purposes of the trade or profession;
  • general provisions for bad debts (specific bad debts and specific bad debt provisions are deductible);
  • dividends or other distributions paid or payable by the company; and
  • certain specific expenses, including business entertainment costs, interest on late payment of taxes, general provisions for repairs and certain motor leasing expenses.

A tax deduction is not available for accounting depreciation. However, capital allowances are available in relation to qualifying capital expenditure on land and buildings, plant and machinery and certain intellectual property.

Chargeable gains that do not form part of the trading profits are calculated in accordance with capital gains tax rules.

R&D Tax Credit

A 25% tax credit for qualifying research and development (R&D) expenditure exists for companies engaged in qualifying in-house R&D undertaken within the European Economic Area (EEA). This credit may be set against a company's corporation tax liability, and is available on a group basis in the case of group companies. The tax credit is calculated separately from the normal deduction of the R&D expenditure in computing the taxable profits of the company.

Qualifying R&D activities must satisfy certain conditions and, in particular, must seek to achieve scientific or technological advancement and involve the resolution of scientific or technological uncertainty.

The R&D tax credit is now payable under a new three-year fixed payment schedule. This change was introduced by amendments included in the most recent Irish Finance Act (Finance Act 2022), which was published on 20 December 2022.

Knowledge Development Box

In 2016, Ireland introduced an OECD-compliant “knowledge development box” for the taxation of certain intellectual property. The amount of expenditure incurred by a company in developing, creating or improving qualifying patents or computer programs (“qualifying expenditure”) is divided by the overall expenditure on such assets before being multiplied by the profits arising from such assets (eg, from royalties and net sales). The result is effectively taxed at 6.25%. A potential 30% uplift in the qualifying expenditure is available, capped at the total amount of acquisition costs and group outsourcing costs.

Finance Act 2022 confirmed the extension of the knowledge development box relief for a further four years.

Capital Allowances on Provision or Acquisition of Intangible Assets

Capital allowances (tax depreciation) are available for companies incurring capital expenditure on the provision of intangible assets for the purposes of a trade. The relief applies to a broad range of intangible assets (eg, patents, copyright, trade marks, know-how) that are recognised as such under generally accepted accounting practice, and are listed as “specified intangible assets” in the Irish tax legislation. The relief is granted as a capital allowance for set-off against profits arising from the use of the intangible assets. The write-off is available in line with the depreciation or amortisation charge in the accounts or, alternatively, a company can elect to take the write-off against its taxable income over a 15-year period.

Where the intangible asset is acquired prior to 14 October 2020 and held for more than five years, there is no clawback of the allowances on a disposal (unless the asset is sold to a connected company that wishes to claim allowances). If an intangible asset is acquired on or after 14 October 2020, a clawback or “balancing charge” will only arise on the disposal of that asset if the sales proceeds are in excess of the “tax written down value” of the asset. The allowance can be surrendered by way of group relief or carried forward if unused.

Digital Gaming Tax Credit

At the start of 2022, Ireland introduced a new tax credit for the digital gaming sector, which will operate as a refundable corporation tax credit for qualifying expenditure incurred in the design and development of digital games. The tax credit will be available at a rate of 32% of qualifying expenditure, with a maximum limit of EUR25 million per project. A per project minimum spend requirement of EUR100,000 will also apply.

Certain reliefs and incentives may apply for companies involved in shipping, financial services, property development, forestry, farming, film production and mining businesses.

Ireland distinguishes between losses arising from trading income and losses arising from non-trading income. Trading losses are computed in the same manner as trading profits. Trading losses may be offset against non-trading profits, but are adjusted on a “value basis” so that they do not reduce the non-trading income more than they would have reduced the trading income.

Broadly, the following actions apply to trading losses, in the following order:

  • trading losses can be set off against other profits of the company (before charges) in the same accounting period;
  • trading losses can be set off against profits (before charges) of the previous accounting period of corresponding length, if the company carried on the trade in that period;
  • trading losses of one Irish company (or of an Irish branch of an EU company) can be set off against the profits of an Irish resident company or Irish branch of an EU company in the same corporate group as the company that has excess trading losses; and
  • trading losses can be carried forward on an indefinite basis and set off against future profits derived from the same trade.

In general, trading companies can only take a deduction for interest incurred wholly and exclusively for the purposes of the trade.

Interest expenses incurred on funds borrowed to purchase, repair or improve rented premises are allowed as a deduction against the related rental income.

Interest incurred by a company on funds borrowed to acquire shares in, or loan money to, certain other companies can be allowable in full against the total profits of the company (as a charge on income), providing specific conditions are met.

While there are no “thin capitalisation” rules that apply in Ireland, it is nonetheless possible in certain limited cases for the interest to be reclassified as a distribution, preventing such interest from being tax-deductible.

The EU Anti-Tax Avoidance Directive (EU ATAD) contains a fixed ratio interest limitation rule (ILR), which was transposed into Irish law in Finance Act 2021 and applies to accounting periods commencing on or after 1 January 2022. The ability to claim a tax deduction for the excess interest is restricted to 30% of EBITDA (earnings before tax and before deductions for net interest expense, depreciation and amortisation). The Irish ILR legislation incorporates a number of important exemptions and exclusions in line with EU ATAD, including an exemption for “standalone entities” and entities whose net interest expense is less than EUR3 million per annum.

Companies can elect to operate the ILR on a single entity or on a local Irish group basis. Moreover, where the taxpayer is part of a consolidated worldwide group for accounting purposes, the indebtedness of the overall group at a worldwide level may be considered for the purposes of providing additional relief under one of two grouping rules.

Finance Act 2022 introduced certain amendments to the ILR. The most significant of the changes is updated relieving provisions for qualifying long-term infrastructure projects, which now include the provision, upgrade, operation or maintenance of a large-scale residential development.

The concept of consolidated tax grouping for corporation tax purposes does not exist in Ireland. Trading losses may be offset on a current-year basis against the taxable profits of another group company.

Both the claimant company and the surrendering company must be within the charge to Irish corporation tax. To form a group for corporation tax purposes, both the claimant company and the surrendering company must be resident in an EU country or an EEA country with which Ireland has a double tax treaty. In addition, one company must be a 75% subsidiary of the other company, or both companies must be 75% subsidiaries of a third company. The 75% group relationship can be traced through companies resident in a “relevant territory” – ie, an EU member state, an EEA treaty country, or another country with which Ireland has a double tax treaty.

Capital gains other than gains from development land are included in a company's profits for corporation tax purposes and are charged to tax under a formula, with the effect that tax is paid at the prevailing capital gains tax (CGT) rate, which is currently 33%.

Substantial Shareholder's Relief

Disposals by a company of a substantial shareholding in a subsidiary company that is resident in an EU member state or a country with which Ireland has concluded a double tax treaty are exempt from CGT if, at the time of the disposal:

  • the subsidiary company carries on a trade, or the activities of the disposing company and all of its 5% subsidiaries taken together amount to trading activities; and/or
  • the disposing company holds or has held at least 5% of the ordinary share capital and economic interest in the subsidiary company for 12 months, beginning not more than two years before the disposal.

Intra-Group Relief

Relief from CGT is available where both the company disposing of the asset and the company acquiring the asset are within a CGT group. A CGT group consists of a principal company and all its effective 75% subsidiaries. In addition, the shares must be within the charge to corporation tax on capital gains both before and after the transfer.

The effect of the relief is that both the company disposing and the company acquiring the asset are treated as if the shares were acquired for such consideration as would secure that neither a gain nor a loss would accrue to the disposing company (that is, the acquiring company takes the shares at the same base cost as applied to the disposing company).

Paper-for-Paper Reconstructions

Where shares are transferred as part of a bona fide scheme of reconstruction or amalgamation and certain additional conditions are met, no CGT arises for the disposing shareholders, and the acquiring shareholders are deemed to have received the shares on the same date and at the same cost as the old shares. The relief will only apply where the company acquiring the shares has – or as a result of the transaction will have – control of the target company, or where the share-for-share exchange results from a general offer made to the members of the target company.

Stamp duty and VAT may be payable by companies on particular transactions.

Stamp Duty

Stamp duty is a tax on certain instruments (primarily written documents). Generally, unless exempted, stamp duty is chargeable on a document if the document is both:

  • of a type set out in Schedule 1 to the Stamp Duties Consolidation Act 1999 (SDCA) (this lists the different categories of document to which stamp duty applies, including conveyances or transfers on sale of stocks or marketable securities and property); and
  • executed in Ireland or, if executed outside Ireland, relates to something done or to be done in Ireland.

Generally, the purchaser or transferee is liable to pay stamp duty arising on a written instrument, and a return must be filed and stamp duty paid within 44 days of the execution of the instrument.

Stamp duty is charged on either the consideration paid for or the market value of the relevant asset, whichever is higher. The main categories of instrument to which stamp duty applies and the applicable rates of the duty are as follows:

  • transfers of shares or marketable securities: 1%;
  • transfers of commercial property: 7.5%; and
  • transfers of residential property:
    1. 1% on consideration up to EUR1 million; and
    2. 2% on the balance of consideration in excess of EUR1 million.

Stamp duty may also be chargeable in connection with certain leases and rent payments.

There are a number of reliefs and exemptions, including:

  • associated companies relief on transfers between companies where the transferor and transferee are 90% associates at the time of execution and for two years afterwards; and
  • exemptions for transfers of intellectual property, non-Irish shares, land, loan capital, aircraft and ships.


VAT is an EU transaction-based tax that is chargeable on the supply of goods and services in Ireland by a taxable person in the course or furtherance of a business. The top rate of VAT is 23% and certain services (such as “financial services”) are VAT exempt. VAT is also chargeable on:

  • goods imported into Ireland from outside the EU;
  • the purchase of certain services from suppliers outside Ireland; and
  • the intra-EU acquisition of goods.

Zoned Land Tax

A new zoned land tax was introduced by Finance Act 2021 to encourage residential construction. The tax applies to land that is zoned as being residential or for a mix of uses, including residential use that is serviced but has not yet been developed for housing. The tax will be based on the market value of the land and at a rate of 3% at the outset. The introduction of the tax will be gradual, with a two-year lead-in time for land zoned before January 2022 and a three-year lead-in time for land zoned after January 2022. This tax is intended to replace the vacant site levy when it comes into operation.

Incorporated businesses operating in certain industries may be subject to additional taxes, such as relevant contracts tax (RCT) and professional services withholding tax. Incorporated businesses are also required to withhold income tax on payments to employees and directors of the company (pay-as-you-earn income tax, or PAYE), and to withhold tax at 20% from payments of interest, dividends and certain royalties (unless exempted). They must also pay social insurance contributions in respect of employees.

Most closely held local businesses operate in corporate form.

Further detail on close companies is set out in 3.3 Accumulating Earnings for Investment Purposes. Closely held companies that are professional services companies are liable to a surcharge on both undistributed investment and rental income and professional income. This surcharge is 15% of 50% of the annual undistributed professional income, and 20% of all of the company's undistributed investment and rental income.

In addition, Irish Revenue guidelines note that the mandating, allocating or routing through a firm or company of remuneration arising from an individual having or exercising an office or employment does not mean that the remuneration is taken outside of that individual's income tax rules.

For Irish tax purposes, a closely held company is a company controlled by five or fewer “participators”, or by any number of participators who are directors. A “participator” is a shareholder or a person having an interest in the company's capital or interest.

Closely held companies are subject to a tax surcharge on investment income (including interest and distributions) or rental income that is not distributed within 18 months of the end of the company's accounting period. This surcharge is 20% of the undistributed income and is intended to act as a disincentive to individuals using corporates as personal holding companies and availing themselves of corporation tax rates that are lower than the tax rates applicable to individuals.

Closely held companies that are professional services companies are liable to a surcharge on both undistributed investment and rental income and professional income, as further described in 3.2 Individual Rates and Corporate Rates.

Irish-resident individuals are liable to income tax at their marginal rate on the gross amount of any dividend received from an Irish company (whether that company is a closely held company or otherwise), with a credit for any dividend withholding tax (DWT) suffered.

Withholding tax at 25% is deducted from payments of dividends by Irish-resident companies to both Irish and non-Irish-resident individuals.

Irish-resident individuals are liable to CGT at a rate of 33% on the sale of shares in an Irish company (whether that company is a close company or otherwise).

Non-Irish-resident individuals are generally only liable to Irish CGT on the sale of unquoted shares in an Irish company if those shares derive the majority of their value from:

  • land and buildings in Ireland;
  • minerals in Ireland and rights or interests associated with mining for or searching for minerals in Ireland; or
  • exploration or exploitation rights in the Irish Continental Shelf.

Finance Act 2022 implemented welcome changes to the Irish Key Employee Engagement Programme (KEEP) share option scheme, which are relevant to SMEs and start-up businesses. KEEP provides for a tax-efficient employee share option scheme whereby, broadly, no tax charge arises when KEEP-compliant share options are exercised by an employee. Instead, a CGT liability will arise when the employee actually disposes of them.

The treatment set out in 3.4 Sales of Shares by Individuals in Closely Held Corporations also applies to dividends from quoted companies and gains on the disposal of shares in quoted companies.

DWT at the standard income tax rate of 25% applies to dividends and distributions made by Irish tax-resident companies.

There are a wide range of exemptions from DWT where the dividend or distribution is paid by an Irish-resident company to certain parties, including:

  • another Irish tax-resident company;
  • companies that are resident in an EU member state (other than Ireland) or a country with which Ireland has concluded a double tax treaty, and that are not controlled by Irish residents;
  • companies that are under the control, directly or indirectly, of a person or persons who are resident in an EU member state or a country with which Ireland has concluded a double tax treaty and are not controlled by persons who are not resident in that country;
  • companies whose shares are substantially and regularly traded on a recognised stock exchange in another EU member state or country with which Ireland has concluded a double tax treaty, or where the recipient company is a 75% subsidiary of such a company or is wholly owned by two or more such companies; and
  • a company resident in another EU member state with at least a 5% holding in the Irish paying company (under Directive 90/435/EEC on the taxation of parent companies and subsidiaries – the Parent-Subsidiary Directive).

Interest Withholding Tax

Irish tax legislation provides that tax at the standard rate of income tax (currently 20%) is required to be withheld from payments of Irish-source interest.

However, a large number of exemptions from the requirement to withhold on payments of interest are available, including for:

  • interest paid in Ireland to a bank carrying on a bona fide banking business;
  • interest paid by such a bank in the ordinary course of business;
  • interest paid to a company that is resident in an EU member state or a country with which Ireland has signed a double tax treaty, where that territory imposes a tax that generally applies to interest receivable in that territory by companies from outside that territory;
  • interest paid to a US corporation that is subject to tax in the US on its worldwide income;
  • interest paid in respect of a “quoted Eurobond” (provided certain other conditions are met); and
  • interest paid to certain Irish entities, including qualifying companies for the purposes of Section 110 of the Taxes Consolidation Act, 1997 (as amended) (TCA), investment undertakings and certain government bodies.

Withholding Tax on Patent Royalties

Withholding tax at a rate of 20% applies to payments of a royalty or other sum paid for the use of a patent.

Withholding tax will not apply to royalty payments that are made to associated companies resident in another EU member state, nor to royalties paid by a company in the course of a trade or business to a company that is resident in a country with which Ireland has a double tax treaty.

It has been Irish Revenue's administrative practice since 2010 not to charge withholding tax on royalties payable under a licence agreement executed in a foreign territory that is subject to the law and jurisdiction of a foreign territory (subject to the Irish company obtaining advance approval from Irish Revenue).

Ireland is an open jurisdiction that encourages investment from all countries; no specific countries are preferred for investing in Ireland. Many US, UK, European, Asian and Gulf Co-operation Council companies invest directly in Irish companies.

Generally, the use of a treaty by a tax-resident beneficial owner should be respected.

Ireland first introduced transfer pricing in 2011, which only applied to trading transactions involving the supply and acquisition of goods, services, money or intangible assets between associated persons or companies. Updated Irish transfer pricing provisions introduced in January 2020 extended the rules to non-trading income and capital transactions.

The rules require that transactions between associated persons should take place at arm's length, and that the principles contained in the OECD Transfer Pricing Guidelines for Multinational Enterprises and Tax Administration, as updated in January 2022, must be followed when analysing whether a transaction has been entered into at arm's length.

If Irish Revenue determines that a transaction was not entered into at arm’s length and has had the effect of reducing profits or increasing losses, an adjustment will be made by substituting the arm’s-length consideration for the actual consideration.

Ireland should follow OECD norms and guidelines in relation to the application of transfer pricing rules.

Finance Act 2019 introduced new changes to Ireland's transfer pricing rules, in part to bring Ireland's transfer pricing legislation in line with the 2017 OECD Transfer Pricing Guidelines, and has applied since 1 January 2020.

There has been an increasing trend for taxpayers and tax authorities to seek resolutions to transfer pricing disputes through the use of mutual agreement procedures (MAPs). This is evidenced by an increase in Ireland’s number of MAP cases in 2018, which rose by over 33% in the 12 months up to January 2019, and then rose again in 2019 by more than 50%.

Irish Revenue operates a formal bilateral advanced pricing agreement (APA) programme. APAs are conducted under the MAPs of the relevant treaty where there are transfer pricing issues involving more than two tax jurisdictions, of which Ireland is one. If requested by the taxpayer, Irish Revenue is also willing, in such cases, to consider conducting multilateral meetings with the other tax administrations subject to the terms of the relevant double tax treaties and the agreement of the other tax administrations.

Although the increasing number of MAP cases would indicate that a proliferation of disputes has occurred in recent years, the prevailing view is that Irish Revenue (as the Irish Competent Authority), where provided with comprehensive supporting transfer pricing documentation by the taxpayer, has shown an ability to resolve disputes on a principled basis that reflects the merits of the Irish taxpayers’ position.

The Irish government has invested in tax administration to reflect the new international tax architecture, including with respect to MAPs and bilateral APAs, which it considers to be important for taxpayer certainty.

Irish Revenue allows for compensating adjustments where a MAP request is made and successfully resolved by Irish Revenue and any other relevant competent authorities. No particular difficulties are faced by claimants where double taxation conventions apply, with Irish Revenue seeking to implement best practice in line with the OECD's Manual on Effective Mutual Agreement Procedures.

Non-resident companies that carry on a trade in Ireland through a branch or agency are subject to corporation tax in the same manner as local companies.

Non-Irish tax-resident companies are liable for tax on gains arising from the disposal of certain assets, including:

  • land and buildings in Ireland (relief from CGT may be claimed in respect of real estate acquired between 6 December 2011 and 31 December 2014 if it was held for a period of at least seven years);
  • minerals in Ireland and rights or interests associated with mining or searching for minerals in Ireland;
  • exploration or exploitation rights in the Irish Continental Shelf;
  • unquoted shares or securities deriving their value or the greater part of their value directly or indirectly from the above assets;
  • assets situated in Ireland that are used, held or acquired for business carried on in Ireland through a branch or agency; and
  • assets of a life assurance company that are situated outside Ireland but held in connection with the life business carried on by the company in Ireland, and that were used or held by or for the purposes of that company's branch or agency in Ireland.

Change of control provisions could arise in relation to the indirect disposal by a non-resident of an Irish land-rich company, as explained under 5.3 Capital Gains of Non-residents.

OECD standards would be expected to be applied in the determination of the income of foreign-owned local affiliates selling goods or providing services.

The basic rule for the allowance of deductions for Irish corporation tax purposes is that the expenses must have been incurred wholly and exclusively for the purposes of carrying on the trade or profession.

Other than as set out below, Ireland does not operate what would be considered statutory thin capitalisation rules.

In broad terms, an Irish-based borrower should be entitled to a tax deduction for payments of interest to a non-local affiliated lender. However, there are certain restrictions that would need to be considered, including but not limited to the following:

  • the interest payments should be an arm's-length amount;
  • the interest payments may be subject to withholding tax if the lender does not fall within relevant exemptions (see 4.1 Withholding Taxes for details of potential exemptions);
  • if the interest expense exceeds its interest equivalent income, the ability to claim a tax deduction for the excess interest may be limited to 30% of EBITDA (see 2.5 Imposed Limits on Deduction of Interest);
  • in certain cases, payments to a non-EU 75%-related affiliate may be recharacterised as a distribution subject to dividend withholding tax and disallowed as a deduction; and
  • where a company borrows to finance the acquisition of shares, there may be a restriction if the lender is related to the borrower, under Section 247 of the TCA.

Foreign income is not exempt from corporate tax. A company that is tax-resident in Ireland is subject to corporation tax on all its profits, wherever they arise, at either 12.5% or 25%.

This question is not applicable in Ireland.

Foreign dividends received by Irish companies are generally subject to corporation tax at a rate of 25%. However, dividends received by an Irish company from non-resident subsidiaries are subject to corporation tax at 12.5% if such dividends are paid out of the trading profits of a company that is resident:

  • in an EU member state;
  • in a country with which Ireland has a double tax treaty;
  • in a country that has ratified the Joint Council of Europe/OECD Convention on Mutual Assistance in Tax Matters; or
  • in a non-treaty country, if the company is directly or indirectly owned by a quoted company.

Companies that are portfolio investors (ie, investors holding not more than 5% of the company and having no more than 5% of the voting rights) and that receive dividends from a company that is resident in an EU member state or a country with which Ireland has a double tax treaty will be subject to corporation tax on those dividends, at the 12.5% rate. Furthermore, where a company is a financial trader, such dividends may be exempt from corporation tax in certain circumstances.

If an Irish company licenses intellectual property to a subsidiary, it will be subject to Irish corporation tax on the licence fees (or deemed licence fees if transfer pricing applies) received in respect of the licence. The rate will be 12.5% if licensing is part of the trading activity of the Irish company, or 25% if it is part of non-trading activity.

Prior to ATAD, Ireland had very limited controlled foreign corporation (CFC) rules. However, ATAD-compliant CFC rules were introduced in Finance Act 2018, with the legislation taking effect for accounting periods beginning on or after 1 January 2019. Of the two frameworks available under ATAD, Ireland chose to adopt the “Option B” model.

Option B focuses on CFC income that is diverted from Ireland. Broadly, CFC income is that which arises to a non-Irish-resident company from non-genuine arrangements put in place for the essential purpose of obtaining a tax advantage. CFC income is attributed to the controlling company or a connected company in Ireland where that controlling or connected company has “significant people functions” (SPF) in Ireland. The CFC charge is based on an arm's-length measurement of the undistributed profits of the CFC that are attributable to the SPF.

Whether a CFC charge is imposed on an Irish controlling company will depend on the extent to which the CFC is regarded as having “non-genuine arrangements” in place. A CFC will be regarded as having non-genuine arrangements in the following circumstances:

  • where the CFC would not own the assets or would not have borne the risks that generate all, or part of, its undistributed income but for relevant Irish activities or SPF being undertaken in Ireland in relation to those assets and risks; and
  • where it would be reasonable to consider that the relevant Irish activities were instrumental in generating that income.

The concept of SPF is not defined in the Irish implementing legislation but must be construed in a manner consistent with the use of that term in the OECD report. If there is no SPF in Ireland to which the management of assets and business risks can be attributed, no tax will arise under the new CFC rules.

The CFC charge applies to the undistributed profits that have been diverted to the low-taxed CFC pursuant to non-genuine arrangements. The rate of Irish tax chargeable will depend on the nature of the income. In Ireland, trading income is taxed at 12.5% and non-trading income is taxed at 25%. A credit is available for any foreign tax paid by the CFC on its undistributed income.

There are no applicable Irish rules relating to the substance of non-local affiliates.

Irish companies are subject to CGT on the sale of shares in directly held non-local affiliates under the normal CGT rules at a rate of 33%, unless the substantial shareholder's exemption or group reliefs apply (as described in detail under 2.7 Capital Gains Taxation).

Ireland does have general anti-avoidance rules, which have recently been amended and are intended to negate the effects of transactions that have little or no commercial reality but are primarily intended to avoid or reduce a tax charge, or to artificially create a tax deduction or tax refund. The anti-avoidance rules mean that Irish Revenue may at any time deny or withdraw a tax advantage created through the use of a tax avoidance transaction by making or amending an assessment of that person.

In determining whether a transaction is a tax-avoidance transaction, regard should be had to the form and substance of the transaction, the substance of any other transactions directly or indirectly related to the transaction, and the final outcome of the transaction and any related transactions.

Where a person enters into a tax-avoidance transaction (ie, one that gives rise to a tax advantage contrary to general or specific anti-avoidance provisions), that person shall be liable to pay a 30% surcharge of the amount of the tax advantage. However, no surcharge is payable by a person who has made a valid protective notification. A taxpayer can also avail themselves of a reduced surcharge amount if a “qualifying avoidance disclosure” is made to Irish Revenue.

Article 6 of the EU ATAD also introduces a broad general anti-avoidance provision. However, the existing Irish general anti-avoidance provisions are regarded as being broader than those contained in Article 6, so no further amendment is envisaged at this time.

Ireland does not have a defined audit cycle for tax purposes: companies are subject to audit by the Irish tax authorities at any time. The time limit for enquiry by Irish Revenue into a tax return is four years from the end of the accounting period in which that return was filed.

In response to the BEPS recommended changes, Ireland introduced country-by-country reporting, updated its transfer pricing legislation in line with 2017 OECD guidelines, and implemented the CFC, anti-hybrid and interest limitation rules under ATAD, among other measures.

Other recent reforms include ratification and implementation of the BEPS Multilateral Instrument, automatic exchange of information under CRS and implementation of Council Directive (EU) 2018/822 (DAC6).

The Irish government is committed to ongoing work on corporate tax reform, and last published an update to its 2018 Corporate Tax Roadmap in January 2021. The Roadmap lays out the next steps in Ireland's implementation of various commitments made through BEPS, along with other international initiatives. In this regard, Irish legislation concerning tax regulation has significantly increased over the last few years, and this effort is set to continue.

With respect to the Irish government's wider attitude, the Irish Department of Finance has insisted that transparency and substance are key components of the Irish tax regime, and is keen to ensure that Irish tax policy is continually in step with all BEPS proposals.

Like other EU member states, Ireland has until 31 December 2023 to transpose the EU directive implementing the Pillar Two Global Minimum Tax Rules. According to a statement given by the Irish Minister for Finance in October 2021, Pillar Two will impact approximately 56 Irish multinational companies and 1,500 foreign-owned multinational companies.

Ireland has fully supported the Pillar One proposals, in recognition of the fact that the way in which business is conducted has evolved and that the taxation system must evolve with it. It is recognised that there will be a cost to Ireland for this in terms of reduced corporation tax receipts, but overall it is considered that Pillar One will bring stability and certainty to the international tax framework and will help underpin economic growth, from which all can benefit.

Pillar One was initially planned to generally apply from 1 January 2023, but this has now been pushed back given the difficulties in reaching international agreement. The OECD plans to have a new Multilateral Convention in place by mid-2023, with Pillar One entering into force in 2024.

The emergence of the double Irish structure, and its subsequent phasing out, along with the EC's Apple State Aid decision (overturned in 2020 by the EU courts and awaiting final judgment), raised the profile of international taxation in Ireland. The Irish media also comments frequently on international tax matters, such as BEPS and US tax reform, given its importance to Ireland as an open economy.

Whilst this has not influenced Ireland's implementation of BEPS, the Irish government has repeated its commitment to update in line with international rules and best practice.

Ireland has undertaken to review its corporate tax code regularly to ensure that new standards such as BEPS are met while remaining competitive as the economy continues to grow. While introducing a minimum rate for larger enterprises (revenue greater than EUR750 million), the Pillar Two reformsare considered as “accommodating appropriate and acceptable tax competition aligned to key principles, such as substance and creation of real value, including Ireland's 12.5% rate.”

For Ireland's tax policymakers, the key balancing task is to ensure that the implementation phase of BEPS would result in the country’s tax regime being seen as meeting the standards for substance and transparency while maintaining the country’s reputation as an open economy that encourages foreign direct investment and has a low rate of corporation tax.

The Irish authorities have firmly voiced their opposition to the EC's interim proposal for a “digital economy tax”, with the Irish Minister for Finance emphasising the need for unanimity before any EU digital tax proposal can be agreed. Similarly, the Irish government has urged caution in respect of the proposed EU Common Corporate Tax Base, stating that discussions on harmonising tax across the eurozone are at a relatively early stage, and that much more technical analysis and discussion are needed.

Ireland has implemented legislation to address hybrid mismatch arrangements as required by ATAD, with effect from 1 January 2020 (1 January 2022 in the case of reverse hybrids).

One of the purposes of the anti-hybrid rules is to prevent arrangements that exploit differences in the tax treatment of a financial instrument under the tax laws of two or more jurisdictions to generate a tax advantage – ie, a “hybrid” situation.

Ireland does not have a territorial regime, but rather taxes companies on a worldwide basis. However, as Ireland is party to a large number of tax treaties, the operation of a foreign tax credit system means that foreign tax paid on income can, in certain cases, be used to offset any Irish tax payable on the same income.

Furthermore, following a review of Ireland's corporate tax code that was commissioned by the Department of Finance in 2017, one of the recommendations was that consideration should be given to moving to a territorial system. In December 2021, the Department of Finance launched a public consultation on a possible move to a limited territorial system of taxation in respect of the income of foreign branches of Irish resident companies and in respect of the payment of foreign source dividends. The public consultation concluded in May 2022, and a limited territorial could be introduced in the future.

Previously, the policy rationale for not adopting a territorial tax system was that Ireland did not have CFC legislation to prevent the artificial diversion of profits to other jurisdictions. However, EU ATAD-compliant CFC rules were introduced into Irish law by Finance Act 2018. In addition, the recent introduction of extended transfer pricing rules, the ATAD ILR and anti-hybrid rules further protect Ireland’s domestic tax base from the artificial diversion of profits and base erosion.

Notwithstanding the fact that the Finance Bill in 2023 will likely already have to deal with Pillar Two and the transposition of several EU Directives, among other things, many of the responses from stakeholders on the consultation say that it is important that Ireland introduces a limited territorial system of taxation.

In Ireland, CFC rules apply to certain foreign subsidiaries, as discussed in 6.5 Taxation of Income of Non-local Subsidiaries Under Controlled Foreign Corporation-Type Rules.

Ireland signed the Multilateral Convention to Implement Tax Treaty Related Measures to Prevent Base Erosion and Profit Shifting (MLI) on 7 June 2017. The MLI came into force in Ireland on 1 May 2019, adopting the principal purpose test (PPT) provisions in its double taxation conventions.

In respect of anti-avoidance rules, Ireland already maintains a long-standing general anti-abuse rule under its tax code. Following a review of the relevant provisions, the Irish tax authorities have indicated that an amendment of the current General Anti-Avoidance Rule will not be necessary. Consequently, the proposed double taxation convention limitation of benefit and anti-avoidance rules are unlikely to have a significant impact on Ireland in respect of inbound and outbound investors.

As Ireland has had transfer pricing rules since 2011, the changes are not expected to present any major hurdles to the Irish regime. Finance Act 2019 introduced changes with effect from 1 January 2020 to bring the current regime in line with the new 2017 OECD Transfer Pricing Guidelines, which reflect the outcomes of BEPS Actions 8–10 and 13.

Country-by-country (CbC) reporting provisions are part of Action 13 of the OECD BEPS Action Plan and the EU Commission’s Anti-Tax-Avoidance Package. CbC reporting requires large multinational enterprises (MNEs) to file a CbC Report providing a breakdown of the amount of revenue, profits, taxes and other indicators of economic activities for each tax jurisdiction in which the MNE group does business. Council Directive (EU) 2016/881 implemented these measures in May 2016, applicable to MNE groups with an Irish presence and turnover exceeding EUR750 million.

The EU Directive on public country-by-country reporting (the “CbCR Directive”) was formally adopted and published in the EU Official Journal in November 2022, and entered into force on 21 December 2022.

The new rules require multinational groups with a total consolidated revenue of EUR750 million to report if they are EU-parented or otherwise have EU subsidiaries or branches of a certain size. The report will require information on all members of the group (including non-EU members) within seven key areas (activities, number of employees, net turnover, profit or loss before tax, tax accrued, tax paid and accumulated earnings).

The information must be broken down for each EU member state where the group is active, and also for each jurisdiction deemed to be “non-co-operative” by the EU or that has been on the EU’s “grey” list for a minimum of two years. Reports are to be published in an EU member state business register, but also on the companies’ websites, where they are to remain accessible for at least five years. When the ultimate parent is not governed by the law of an EU member state, the reporting will generally have to be done by the EU subsidiaries or branches, unless the ultimate parent publishes a report including those subsidiaries and branches.

Furthermore, Finance Act 2019 introduced new rules giving effect to DAC6. The EU DAC6 Mandatory Disclosure Rules legislation provides for the sharing of taxpayer information between the tax administrations of EU member states. DAC6 introduced a mandatory disclosure regime for certain cross-border transactions and came into effect on 1 July 2020.

No changes have been discussed or proposed at a domestic level.

On 13 October 2022, the EU Commission launched a public consultation entitled “Business in Europe: Framework for Income Taxation” (BEFIT), in accordance with which it aims to propose a directive by the third quarter of 2023 on a common set of rules for EU companies to calculate their taxable base with an allocation of profits between EU member states based on a formula.

The Commission argues that the proposal will reduce compliance costs by creating a coherent approach to corporate taxation in the EU, but the proposal and its predecessor (the common consolidated corporate tax base) have long been controversial and resisted by a number of member states, including Ireland.

The Irish government opposed the EC's interim proposal for a “digital economy tax”, with the Irish Minister for Finance referencing the OECD reports on digital taxation and the need for broader international consensus on this issue, rather than EU-focused measures. The Irish government also published a reasoned opinion on 16 May 2018, addressed to the President of the EU Council, questioning the necessity of these measures. Accordingly, Ireland does support the OECD Pillar One initiative (see 9.2 Government Attitudes).

Payments of patent royalties by an Irish resident company are typically subject to withholding tax at 20%. Patent royalties paid to associated companies resident in another EU member state or paid in the course of a trade or business to a company resident in a country with which Ireland has a double tax treaty are generally exempt from withholding tax. Irish Revenue issued a Statement of Practice in 2010, which effectively extends the relief from withholding tax on certain patent royalties paid to non-treaty countries. To avail of the exemption, certain conditions apply, including the fact that the royalty must be paid in respect of a foreign patent and the payment must be made in the course of the Irish paying company's trade. Prior approval from Irish Revenue will be required.

Living in Interesting Times – the Quest for Certainty

The winds of change that have swept through the international tax landscape in recent years show no signs of abating, and reform remains the order of the day. The scale of recent reformative measures has resulted in Ireland's tax code becoming broader and more sophisticated, but also more complex. This complexity has resulted in increased scope for disagreement between taxpayer and tax authority, as both sides seek to interpret and apply the new rules. In line with Ireland's well-established track record in international business, the increased scope for uncertainty and dispute has been counterbalanced by significant investments in resources for dispute avoidance and resolution.

This article will examine a number of recent developments and trends in key areas of Irish tax practice that are likely to have an impact on the quest for certainty in coming years.

The OECD's two pillars

The OECD's two-pillar proposal will result in major reform of the international tax framework and the introduction of new rules and concepts. Ireland is actively engaged with both pillars and is likely to introduce relevant measures in line with EU timelines. As such, Ireland is expected to fully transpose the Pillar Two EU Directive (the “Directive”) with effect for accounting periods commencing on or after 1 January 2024.

In light of the scale of the Pillar Two rules, there is considerable work to be done as part of Ireland's transposition to ensure that, among other things, the new rules can operate harmoniously within Ireland's tax code and not produce any unintended consequences. Some steps have already been taken to address identified anomalies, including the following.

  • Research and Development (R&D) tax credit: Ireland's R&D tax credit rules have been amended to ensure that the credit is a qualifying refundable tax credit for Pillar Two and US foreign tax credit purposes.
  • Knowledge Development Box (KDB): the effective tax rate of the KDB (ie, Ireland's patent box) will be increased to 10% (from 6.25%) to align with the Pillar Two “subject-to-tax rule” once agreement on implementation is reached at the OECD/G20 level. It remains to be seen what further changes will be required to align the KDB (which reduces a taxpayer's effective tax rate by way of tax deduction) with Pillar Two more generally.
  • Territorial tax system: in conjunction with the implementation of Pillar Two, Ireland is also considering moving towards a territorial corporation tax system, which will include a dividend participation exemption and a foreign branch exemption to replace the current credit-based system. This would better accommodate the implementation of the Pillar Two rules by providing for greater clarity and significantly less complexity in the tax code.

Ireland is also very likely to introduce a Pillar Two-compatible qualifying domestic top-up tax.

In line with recent experiences, the government is expected to publish a number of consultations throughout 2023 on the transposition of the Directive, to minimise uncertainty and complexity in the legislative process and to ensure provisions are well considered and signposted in advance. In addition to the anomalies identified above, the interaction of Ireland's Pillar Two rules with US global intangible low-taxed income (GILTI) and foreign tax credit rules will be particularly important to many multinational taxpayers who have a significant presence in Ireland. From a policy perspective, Ireland is expected to take all reasonable steps available to minimise any uncertainty in this context.

Digital services taxes (DSTs)

The delayed implementation of the OECD's Pillar One proposal means that DSTs are likely to remain a feature of the international tax landscape for the short term at least. DSTs present several challenges for multinational taxpayers as they are typically structured to fall outside the scope of double tax treaties, which can give rise to uncertainty as to the creditability of the relevant DST.

Helpfully, Irish Revenue recently published guidance confirming that, when incurred wholly and exclusively for the purposes of a trade, the DSTs imposed by certain countries including Austria, France, Italy, Spain, the UK and India may be treated as tax-deductible expenses. Irish Revenue confirms that the deductibility of DSTs imposed by other countries will be confirmed on a case-by-case basis. As such, the list of countries specified in the guidance is expected to continue to grow as other DSTs are considered in practice.

Although Irish Revenue's published position aligns with established tax law principles on deductibility, the guidance has eliminated some of the uncertainty that existed in the market around the tax treatment of DSTs.

Transfer pricing (TP)

Ireland's TP rules were significantly expanded with effect from 1 January 2020; as such, the expanded rules are now live in the audit cycle. The expansion of the TP regime was accompanied by an enhancement in Irish Revenue's TP capabilities and, in practice, there has been a noticeable increase in TP-related queries and audits initiated by Irish Revenue in recent years. This increased audit activity has, in turn, resulted in an increase in TP-related disputes, and this trend is expected to continue over the coming years.

The TP queries taxpayers are facing from Irish Revenue range from general queries on the application and administration of group TP policies to specific queries on the suitability of a particular methodology or the approach applied to pricing intangibles.

Tax authorities in market jurisdictions continue to challenge the TP applied to transactions with principal companies in supply chains. In recent years, there has been an increased focus on the application of Chapter IX of the OECD's TP guidelines (the TPG) to group restructuring transactions, with many tax authorities adopting a narrow approach to such transactions in a bid to maximise taxing rights.

The recent trends in TP challenges are expected to continue in Ireland and internationally in the coming years, as additional tax periods are audited through the lens of the updated TPG.

Customs & Excise (C&E)

C&E duties is another area where there has been, unsurprisingly, a significant increase in activity in recent years. The UK's withdrawal from the EU remains a source of uncertainty in practice as the scope of the EU-UK Trade and Cooperation Agreement continues to be explored. This uncertainty is compounded by ongoing political developments surrounding the Northern Ireland Protocol.

In response to Brexit, Irish Revenue increased its C&E capacity significantly, resulting in C&E audit queries becoming more prevalent in practice. Increasingly, the focus of C&E audit queries has gone beyond importers of goods for resale to include the importation of plant and machinery for use in a business and the interaction of TP adjustments on a taxpayer's liability to C&E duties.

Financial services

Ireland's participation in the OECD's BEPS initiative resulted in the introduction of a number of new rules and regimes into the Irish tax code following the Anti-Tax Avoidance Directives (ATAD). This included the introduction of general anti-hybrid rules and an interest limitation rule (ILR) in accordance with ATAD.

These tax rules are particularly relevant in financial services transactions in Ireland, such as collateralised loan obligations, securitisations and asset financing (such as aircraft), where financing vehicles depend on interest deductibility to manage their tax base. Most financial services structures that implement lending or credit strategies (and primarily earn interest or equivalent income) fall outside the scope of the ILR. There are also exemptions from the ILR for structures that are not financially consolidated with other entities or that form part of financially consolidated groups with a comparable capital structure. The ILR took effect in Ireland from 1 January 2022. As a result, the impact (if any) of the ILR will be the likely focus of the 2023 audit and tax compliance cycle and queries from the Irish tax authorities.

Financial year 2022 was a notable year for the formation of tax transparent Irish limited partnerships (ILPs), with a material increase in the number of ILPs formed and strong interest in ILP formations from both managers and investors.

Ireland also implemented the BEPS reverse hybrid rule with effect from 1 January 2022. This rule applies to transparent funds and can impose a tax charge on ILPs if a material investor (50% or more) treats the ILP as tax opaque. Ireland implemented the reverse hybrid rule flexibility, so that unconnected investors are not automatically aggregated to reach the 50% threshold and hybrid outcomes do not arise if a material investor is tax-exempt or established in a jurisdiction that does not impose tax. This has meant that the reverse hybrid rule has largely had no material impact on ILPs and can easily be managed by ILPs and investment managers.

In all cases, Ireland's implementation of general anti-hybrid rules, the ILR and the reverse hybrid rule has required tax advisers in Ireland to conduct greater tax diligence on upstream fund and financing structures to understand the tax treatment of ultimate investors. Evidence of this diligence is being required by audit firms and tax compliance agents to support annual tax compliance in Ireland, and may be sought by the Irish tax authorities.

Tax disputes have also become more commonplace in the financial services industry. A number of Irish tax court judgments in 2022 are directly relevant to the financial services industry, including with respect to the proper tax treatment of debt forgiveness. It is also understood that there are a number of judgments to be published which will be of interest to the industry, including whether loans secured on Irish real estate are within the charge to Irish capital gains tax and whether certain foreign withholding taxes are deductible for Irish corporation tax purposes.


The Swedish presidency of the Council of the EU has brought renewed vigour to the proposal for an EU directive targeting the use of so-called “shell” entities (ATAD III). Although the revised scope of ATAD III remains to be seen at the time of writing, it is expected that Ireland will seek to transpose any measure introduced with the same business-focused pragmatism that was applied to the transposition of the EU's ATAD I and II directives.

Stamp duty on public takeovers

In general, a transfer of shares in an Irish company is subject to stamp duty at 1% of the market value of the relevant shares. Prior to a change in domestic tax law introduced in October 2019, Irish public company takeover transactions were typically effected by way of a cancellation scheme of arrangement, which did not involve a transfer of shares and did not therefore trigger Irish stamp duty.

The 2019 law change was successfully challenged by a taxpayer before the Tax Appeals Commission (TAC) (ie, Ireland's tax court) as being contrary to the EU Capital Duties Directive. However, the dispute did not reach the constitutional courts so the relevant provision remains in the domestic tax code. As such, there remains uncertainty as to the correct application of Irish stamp duty in the context of public company takeover transactions. It is likely that this uncertainty will persist until the law is challenged before the constitutional courts, as there is currently no indication that the law will be revised by the legislature voluntarily.

Resolving uncertainty

It is clear from the foregoing that the unprecedented scale of international tax reform in recent years has produced inevitable uncertainty, which is likely to persist, for the short term at least, as the new rules bed down.

A number of actions have been taken in Ireland to counteract this uncertainty and to provide as much clarity for taxpayers as possible in the circumstances. In particular, significant investment has been made in Ireland's tax dispute resolution fora in a domestic and international context to ensure that the inevitable divergences on the application of the new rules can be settled in an efficient and effective manner.

In a domestic context, TAC has been reformed and modernised, and now operates as a key driver in resolving complex and high-value disagreements between taxpayers and Irish Revenue. TAC’s continuing success in this context is reflected in the following combined statistics for 2021 and 2022:

  • 4,454 tax appeals were closed, representing more than EUR3.7 billion of disputed tax (the majority of which was corporation tax);
  • 2,928 new tax appeals were received and 741 hearings were scheduled; and
  • 320 final determinations were issued.

Interestingly, the statistics also highlight TAC's effectiveness in facilitating resolution by settlement between taxpayer and Irish Revenue, particularly in higher value disputes. For example, in 2021 (the figures for 2022 have not yet been released), 92% of the total tax in dispute in cases scheduled for hearing was resolved by pre-hearing settlement or withdrawal of proceedings.

In an international context, the Irish competent authority (CA) team has been enhanced with significant investment in response to the material increase in Ireland's mutual agreement procedure (MAP) caseload. For example, Ireland had 43 open MAP cases on 1 January 2017, but this figure grew to 151 within four years.

Ireland's investment in, and the practical and principled approach of, the Irish CA team is reflected in the team's impressive performance in resolving disputes efficiently. In 2021 (the figures for 2022 have not yet been released), the Irish CA team closed 172 MAP cases and was recognised with a number of OECD awards, including:

  • the shortest average time to close MAP cases in the non-TP category, taking approximately five months to close non-TP MAP cases; and
  • first place in the caseload management category for having the highest closing ratio of TP and other cases (in other words, of the jurisdictions with the most MAP cases, Ireland closed more cases than any other jurisdiction).

The applicability of mandatory binding arbitration (MBA) to MAP cases will further enhance the efficiency of the Irish CA team in resolving international disputes. Although the exact impact of MBA on MAP cases will not be reflected in statistics for a number of years, in practice the positive effect of MBA on MAP proceedings is already apparent.
