Ireland – Taxation

How does the tax system in Ireland work?

Ireland operates a single, centrally managed tax system, with the Revenue Commissioners responsible for its administration at a national level. Unlike federal systems such as those found in the United States or Germany — where taxpayers must contend with overlapping federal, state, and local charges — Ireland imposes no regional or municipal income taxes. This relatively streamlined structure can make it easier to navigate for those arriving from more complex jurisdictions.

Your exposure to Irish tax is shaped by three distinct but interrelated concepts: residence, ordinary residence, and domicile. These can apply in various combinations. Where you are both resident and domiciled in Ireland for tax purposes, your entire worldwide income — everything you earn anywhere across the globe during the tax year — falls within the Irish tax net.

Tax residency in Ireland is triggered by one of two tests: the 183-day rule, under which spending 183 or more days in the country during a single tax year makes you resident, or the 280-day rule, which catches individuals who spend 280 or more days across two back-to-back tax years, provided at least 30 of those days fall in each year. A notable feature of the Irish rules is that even a partial day — such as arriving late at night — counts as a complete day for the purpose of these calculations.

Ordinary residence is a separate concept acquired after three consecutive years of tax residency; from the fourth year, you are considered ordinarily resident. This status does not simply fall away when you depart from Ireland. It persists for the three tax years following the last year in which you were actually tax resident, which can produce ongoing obligations well after you have physically left the country.

Domicile, meanwhile, refers to the jurisdiction you regard as your permanent home — the place you intend to settle indefinitely. It is legally distinct from both nationality and where you currently live, and it carries significant weight in determining how foreign income is treated, most notably through the remittance basis available to those who are not Irish-domiciled.

For those in employment, the Pay As You Earn (PAYE) system means that employers calculate and deduct income tax, PRSI, and USC directly from wages before they are paid, passing those amounts straight to Revenue. Most employees will find their tax position settled automatically through PAYE, without needing to file a return, though this depends on their individual circumstances. Always refer to the Revenue website for the most up-to-date guidance.

Does Ireland have double taxation agreements, and how do they affect expats?

Ireland maintains one of the most extensive treaty networks within the EU. As of 1 November 2025, 78 double taxation agreements (DTAs) have been signed, 75 of which are currently in force, and they generally follow the framework of the OECD Model Convention. Beyond these, Ireland has concluded 10 social security agreements and 2 treaties specifically addressing estate, gift, and inheritance tax.

The purpose of a DTA is to prevent the same income from being subjected to tax in two countries simultaneously. In practice, treaties typically assign taxing rights over particular categories of income to one jurisdiction or the other, or provide for a credit mechanism whereby tax paid in one country can be offset against the liability arising in the other. If you are tax-resident in Ireland, you are required to declare foreign income to Revenue — but where a relevant DTA applies, it may substantially reduce what you actually owe.

Revenue can issue a Letter of Residence confirming your tax residency status to a foreign tax authority where a DTA is in place. This document may only be used for that specific purpose and cannot be applied in any other context. Requests can be submitted through the ‘Manage My Record’ section of myAccount.

Ireland’s complete and current list of tax treaties is maintained on the Revenue Commissioners’ treaty database. Since the terms of individual treaties vary and the network continues to grow, it is worth consulting this database directly and, where cross-border income is involved, seeking the assistance of a tax adviser with international expertise.

What taxes do expats need to pay in Ireland?

Becoming tax-resident in Ireland will bring you into contact with a range of taxes. The principal ones are described below, with rates reflecting the position as of 2025 unless stated otherwise. Given that rates and thresholds are subject to revision through the annual Budget process, you should always verify the current figures on the Revenue website.

Income Tax

Irish income tax operates through a two-rate structure linked to a standard rate cut-off point. Earnings up to that threshold are taxed at 20%, while anything above it is taxed at 40%. For single individuals and widowed taxpayers without qualifying dependent children, the standard rate band extends to €44,000 (as of 2025), with the 40% rate applying to any surplus. Married couples where one spouse works enjoy a higher 20% band ceiling of €53,000, and where both spouses are employed, they may share a combined standard rate band of up to €88,000.

Universal Social Charge (USC)

The Universal Social Charge applies to gross income — your total earnings before pension contributions, PRSI, or other deductions are removed. Unlike income tax, it is not reduced by most tax reliefs. As of 2025, the applicable rates are 2% on income between €12,013 and €27,382; 3% on income from €27,382 to €70,044; and 8% on income above €70,045. Anyone whose total income does not exceed €13,000 in the year is not liable to USC at all.

Pay Related Social Insurance (PRSI)

PRSI is Ireland’s social insurance contribution system, serving a comparable function to national insurance contributions in certain other countries. With effect from 1 October 2025, the employee PRSI rate rose to 4.2%. Employees whose weekly earnings are €352 or below are not required to pay PRSI. Contributions build entitlement to benefits such as the State Pension and Jobseeker’s Benefit, making compliance valuable beyond the immediate tax context.

Capital Gains Tax (CGT)

Capital Gains Tax is charged at 33% on taxable gains arising from the disposal of assets. A 40% rate can apply to gains from certain foreign life assurance policies and offshore investment products. Each individual benefits from an annual exempt amount of €1,270, which cannot be transferred between spouses though each may claim their own. The disposal of a principal private residence is generally relieved from CGT. Non-residents’ exposure to CGT in Ireland is broadly confined to the disposal of specified Irish assets, including land and buildings situated in Ireland and shares deriving their value primarily from such assets, with the precise position depending on residency and domicile status.

Capital Acquisitions Tax (CAT) — Gifts and Inheritances

CAT is the tax levied on assets transferred either on death or as lifetime gifts. An acquisition is brought within the Irish CAT net where either the person making the gift or inheritance, or the person receiving it, is resident or ordinarily resident in Ireland — regardless of domicile. Assets physically situated in Ireland are also subject to CAT irrespective of where the parties are resident. As of 2025, the rate stands at 33% on the taxable value above the relevant threshold. These thresholds depend on the relationship between the parties: Group A (for example, a child receiving from a parent) is €335,000; Group B (for example, siblings, nieces, or nephews) is €32,500; and Group C (unrelated parties) is €16,250. These are lifetime cumulative limits rather than per-transaction allowances.

Local Property Tax (LPT)

LPT is levied annually on residential properties located in Ireland, calculated by reference to the property’s market value. Rates are set by local authorities and vary by valuation band. Liability rests with the property owner regardless of whether they are living in Ireland — so expats who own Irish residential property while residing abroad remain obligated to pay. There are 19 valuation bands, spanning from properties worth less than €200,000 (attracting an LPT charge of €90) up to those valued at up to €1.75 million (attracting a charge of €2,721).

Stamp Duty

Stamp duty is payable when purchasing property in Ireland. For residential property, the rate is 1% on the first €1 million of the purchase price and 2% on any amount above that. Non-residential property transactions are subject to a 7.5% rate, while transfers of shares attract stamp duty at 1%.

Are there any tax breaks or special regimes for expats in Ireland?

Ireland does not provide a single sweeping preferential tax programme of the kind seen in, for example, Portugal’s former Non-Habitual Resident regime or Italy’s flat-tax arrangement for new arrivals. Nonetheless, a number of provisions can meaningfully reduce an expat’s tax burden, particularly during the initial years of Irish residence.

The Remittance Basis for Non-Domiciled Individuals

For many newly arrived expats, this is the most valuable relief on offer. It applies to individuals who are tax-resident in Ireland but whose domicile lies outside the country. Under the remittance basis, overseas-source income — such as returns from foreign investments or business activities conducted abroad — is only liable to Irish tax to the extent that it is brought into Ireland. Foreign income left outside the country entirely escapes Irish taxation.

More precisely, where an individual is non-resident or not ordinarily resident, only Irish-source income is taxable in Ireland. Where someone is resident or ordinarily resident but not domiciled in Ireland, both Irish-source income and any amounts remitted to Ireland fall within the charge to tax. This makes the remittance basis a genuinely useful planning tool for non-domiciled residents who are careful about what they transfer into Irish bank accounts or spend while in Ireland.

The Irish remittance basis shares a conceptual similarity with the treatment historically available to non-domiciled residents of the UK, though the specific rules differ considerably. One particularly attractive feature of the Irish approach is that no annual charge is levied simply for accessing this basis — unlike some comparable regimes elsewhere — making it potentially very advantageous for those with substantial foreign income. Proper structuring before arrival is essential, so professional advice is strongly recommended.

Split-Year Relief

Where an individual moves to or from Ireland part way through a tax year, Split-Year Relief may operate to confine Irish tax liability to only the period of actual residence in the country. Under this relief, foreign income earned prior to arriving in Ireland, or after departing permanently, may be excluded from the Irish charge. The relief must be actively claimed and is conditional — speak with Revenue or a qualified tax adviser to establish whether you are eligible and how to apply.

Foreign Earnings Deduction and Special Assignee Relief Programme (SARP)

The Special Assignee Relief Programme is designed to encourage international businesses to locate senior staff in Ireland. Qualifying employees who are transferred to Ireland by their employer can access income tax relief on a defined portion of their earnings. To qualify, conditions must be satisfied including a minimum salary level, assignment from a country with which Ireland has concluded a DTA, and the claim must be made in the year of arrival. Because SARP is periodically reviewed and its terms may be updated, you should always confirm the current eligibility criteria and relevant income thresholds directly on the Revenue website before incorporating it into your planning.

Foreign Tax Credits

Residency and domicile status are relevant across a range of taxes in Ireland, including income tax, Deposit Interest Retention Tax (DIRT), Capital Acquisitions Tax, and Capital Gains Tax. Where a DTA is operative, it generally permits a credit for tax already paid to a foreign jurisdiction to be set against the corresponding Irish liability on the same income. This mechanism prevents genuine double taxation in practice, even for those who do not fall within the formal remittance basis rules.

How and when do expats file a tax return in Ireland?

Ireland’s tax year runs from 1 January to 31 December. Those with income outside of PAYE are required to operate within a self-assessment framework, and the vast majority of tax interactions can be handled through Revenue’s digital platforms. The primary deadline for self-assessed returns is 31 October each year, with a later deadline generally available to those who both file and pay using Revenue’s Online Service (ROS). Exact extended deadlines are confirmed annually, so check the Revenue website to confirm the current year’s dates.

1. Obtain a Personal Public Service (PPS) Number. A PPS Number is a prerequisite for all dealings with the Irish tax system. Applications are made through the Department of Social Protection. Without one, you cannot register with Revenue, open a bank account, or access most public services.
2. Register with Revenue. Once you hold a PPS number, you can register with Revenue. Resident individuals, partnerships, trusts, and unincorporated bodies use Form TR1. Self-employed individuals and those receiving income outside PAYE must register for income tax through Revenue’s myAccount portal or the Revenue Online Service (ROS).
3. Establish access to myAccount or ROS. ROS is the main platform used by self-assessed taxpayers to manage their tax affairs, submit returns, and claim refunds. PAYE employees use the equivalent myAccount portal. Both services are accessed via revenue.ie.
4. Identify your filing obligation. Individuals who receive both PAYE and non-PAYE income above the relevant threshold must file a return. Self-employed persons, or those with non-PAYE income exceeding €3,174, are required to submit a Form 11. Employees whose income is entirely from PAYE employment generally have their tax settled at source and may only need to file if they wish to claim credits or reliefs not automatically applied.
5. Submit your return and settle any outstanding tax. Paper returns must reach Revenue by 31 October; ROS users who both file and pay electronically typically benefit from an extension to mid-November. For CGT, the tax on gains arising between 1 January and 30 November in any given year must be paid by 15 December of the same year, with the associated return due by 31 October of the following year.
6. Retain records. You are required to keep supporting documentation — including payslips, rental receipts, investment account statements, and evidence of any foreign income or assets — for a minimum of six years.

Filing a return late or settling tax after the due date carries consequences in Ireland. Revenue may apply a surcharge to the outstanding liability, and interest accrues on unpaid amounts. Engaging an accountant or tax adviser with experience of expat situations well ahead of the October deadline is strongly advisable.

What are the tax implications of leaving Ireland?

Many expats assume that their Irish tax obligations come to an end the moment they leave the country — but this is frequently not the case, and misunderstanding the rules in this area can prove costly. The central issue is the concept of ordinary residence: once you have acquired this status, it does not simply cease when you depart. You remain ordinarily resident in Ireland for the three full tax years following the last year in which you were actually tax-resident, potentially creating ongoing Irish tax exposure long after you have established yourself elsewhere.

An individual who is ordinarily resident may remain liable to Irish income tax on worldwide investment income even if they no longer satisfy the physical presence tests for tax residency and are living permanently abroad. This distinguishes Ireland from many other countries, where crossing the border and breaking the physical connection is sufficient to end tax liability. Careful planning in advance of departure — ideally with the involvement of a tax professional — is essential if you have significant investment income or hold foreign assets.

Ireland also levies an exit tax on certain unrealised gains. This charge can arise when a person who has been Irish tax-resident holds interests in investment funds or life assurance policies and subsequently ceases to be resident. The exit tax treats the embedded gain in those assets as though it had been realised at the point of departure, crystallising a tax liability at that moment. The applicable rates and precise conditions are subject to change, so current rules should be confirmed on the Revenue website before making any decision to leave.

CAT continues to apply in circumstances where the donor or recipient of a gift or inheritance is resident or ordinarily resident in Ireland, regardless of domicile. Additionally, assets physically situated in Ireland remain within the CAT net irrespective of where the parties are resident. This means that even after departure, Irish property or assets you own or transfer could still attract Irish inheritance and gift tax.

If you retain ownership of Irish residential property following your departure, LPT liability continues regardless of where you are living. Before leaving Ireland, you should also ensure that any outstanding returns have been filed, all tax liabilities have been settled, and you have taken appropriate steps to formally adjust your registration with Revenue — failure to do so can result in penalties and interest building up in your absence.

Practical tips for managing taxes as an expat in Ireland

• Keep a precise record of your days in Ireland from the outset. Since even a partial day qualifies as a full day for residency purposes, a detailed travel log is essential. This record will be invaluable for determining when tax residency is triggered and for managing your position under the two-year 280-day rule.
• Clarify your domicile position before you arrive. Non-Irish domicile opens the door to the remittance basis, which can be a powerful planning tool. However, domicile is a nuanced legal concept and should not be assumed without proper advice — seek professional guidance before relying on any particular position.
• Claim Split-Year Relief if you are arriving partway through the year. This relief can cap your Irish tax exposure to the period you are actually resident. It requires an active claim, so inform Revenue or your adviser at the time you take up residence.
• Be disciplined about what funds you bring into Ireland if you are relying on the remittance basis. Transferring foreign income into Irish accounts or using it while in the country can bring it within the Irish tax charge. Mixing remitted and non-remitted funds can complicate matters considerably.
• Consider the timing of any foreign asset disposals carefully. Once you are Irish tax-resident, selling assets held abroad may generate an Irish CGT liability even where the asset is not in Ireland. In some cases, disposing of assets before establishing Irish residency can lawfully avoid this outcome — take advice early.
• Be aware of the ordinary residence consequences before your third year of residence. If you intend to stay in Ireland for only a few years before moving on, failing to plan around the ordinary residence rules can result in tax obligations that outlast your time in the country. Seek advice before the end of your third year of residency.
• Register for myAccount or ROS as soon as possible. Getting set up on Revenue’s online platforms early makes ongoing compliance considerably more straightforward and allows you to respond promptly to any queries from Revenue.
• Monitor Ireland’s annual Budget announcements. Tax rates, bands, credits, and PRSI rates can all be adjusted through the annual Budget, which is typically delivered in October. Reviewing the changes each year ensures you are working with current figures and not outdated assumptions.
• Engage a qualified tax professional with cross-border experience. The interaction between residency, ordinary residence, domicile, and Ireland’s treaty network is genuinely complex. Working with a Chartered Tax Adviser (CTA) who understands expat and international tax issues is one of the most valuable steps you can take, particularly in your first year in Ireland.

Frequently asked questions: taxation in Ireland for expats

When do I become a tax resident in Ireland?

Tax residency in Ireland arises when you spend 183 days or more in the country during a single tax year, or when you accumulate 280 or more days across two consecutive tax years with at least 30 of those days in each year. Ireland’s tax year runs from 1 January to 31 December. Any portion of a day spent in Ireland — however brief — is counted as a full day for the purpose of these thresholds.

Is my worldwide income taxable in Ireland once I move there?

If you are both resident and domiciled in Ireland for tax purposes, your entire worldwide income — everything earned anywhere in the world during the tax year — is liable to Irish tax. If you are resident but not domiciled in Ireland, only foreign income actually brought into the country is taxable under the remittance basis. Individuals who are not resident in Ireland are generally liable only on income that has an Irish source.

How is foreign pension income taxed in Ireland?

Where you are Irish tax-resident, a foreign pension typically forms part of your worldwide income and is in principle taxable in Ireland. However, a double taxation agreement between Ireland and the country from which the pension is paid may limit or eliminate the Irish charge, or entitle you to credit for foreign tax already deducted. The outcome depends on the specific provisions of the relevant treaty — consult the current list of Irish treaties at revenue.ie and take professional advice on your particular circumstances.

What is the remittance basis and who qualifies for it?

The remittance basis is a form of tax treatment available to individuals who are tax-resident in Ireland but are not Irish-domiciled. Under this basis, foreign-source income is only brought within the Irish tax charge to the extent that it is remitted into Ireland — that is, physically transferred in or otherwise used here. Foreign income retained entirely outside Ireland is not taxed. The basis is only available to those whose domicile lies outside Ireland and does not apply once an individual has become Irish-domiciled.

What is the deadline for filing a tax return in Ireland?

The standard deadline for self-assessed returns is 31 October each year, relating to income earned in the preceding tax year. Taxpayers who both file and pay online using Revenue’s ROS platform typically benefit from an extended deadline, usually falling in mid-November. For CGT purposes, tax on gains made between 1 January and 30 November must be paid by 15 December; the accompanying tax return is due by 31 October of the following year. Current deadline dates should always be confirmed at revenue.ie.

Does Ireland have a wealth tax or net worth tax?

There is no annual wealth tax or net worth tax in Ireland levied on the overall value of assets held. There is, however, a Domicile Levy — a charge of up to €200,000 — which can apply to individuals who are Irish-domiciled, whose worldwide income exceeds €1 million, whose Irish assets exceed €5 million, and who are not already paying at least €200,000 in Irish income tax. This is a relatively narrow provision that will not affect the majority of expats. For full details, refer to revenue.ie.

Will I still owe Irish tax after I leave Ireland?

Leaving Ireland does not automatically extinguish your Irish tax obligations. Ordinary residency, once acquired, persists for the three tax years following the last year of actual tax residency, during which certain categories of income — notably foreign investment income — may remain liable to Irish tax. Ireland additionally imposes an exit tax on unrealised gains embedded in particular investment structures, triggered at the point you cease to be tax-resident. Professional advice ahead of any planned departure is essential to manage these risks effectively.

Do I need a PPS number to register for tax in Ireland?

Yes — a PPS Number is a fundamental requirement for engaging with the Irish tax system and a wide range of other services. Applications are made through the Department of Social Protection, either at a local Intreo Centre or, in certain circumstances, online. Once you have your PPS number, you can register with Revenue for income tax, CGT, and other taxes through the myAccount or ROS platforms, both accessible at revenue.ie.
