Revenue-compliant guidance based on s.865 TCA 1997 (right to repayment of overpaid Irish income tax), updated for 2025. Revenue source →
Irish workers who have emigrated can claim a refund of any Irish income tax overpaid while they worked in Ireland, under s.865 TCA 1997. The four-year backdating rule applies regardless of where you now live — in 2025, you can claim for Irish income earned in 2022, 2023, 2024, and 2025. Claims can be submitted entirely remotely through MyTaxRebate without returning to Ireland or contacting Revenue directly. The most common sources of refunds for emigrant workers are unused credits for the portion of the year after leaving, emergency tax applied in the final months of employment, and qualifying expense reliefs (medical, flat-rate) incurred during Irish employment.

Who Can Claim Irish Tax Back After Leaving?
Any person who was employed in Ireland and paid income tax through the Irish PAYE system can claim a refund of any overpaid tax under s.865 TCA 1997, provided the claim is made within four years of the end of the relevant tax year. Current residence is irrelevant — the entitlement is based on having paid Irish PAYE tax, not on being resident in Ireland at the time of the claim. This applies to:
- Irish citizens who emigrated to Australia, the UK, the US, Europe, or any other country
- Non-Irish workers who worked temporarily in Ireland and returned home
- Workers who moved to the UK post-Brexit and paid Irish PAYE during their Irish employment
- EU workers who worked in Ireland and moved back to their home country
- Cross-border workers who lived in Northern Ireland and worked in the Republic (separate treatment for cross-border claims)
Why Leaving Ireland Mid-Year Creates a Refund
When employment in Ireland ends mid-year, annual tax credits are allocated for a full year but income is only earned for the months worked. The credits attributable to the period after leaving are unused and refundable. For a worker who leaves in May, seven months of credits remain unused. The earlier in the year you leave, the larger the credit-based refund.
How the Claim Is Made Remotely
MyTaxRebate manages emigrant claims entirely remotely. You complete our online application from wherever you are located, provide scanned or digital copies of your payslips, P45, and any expense documentation, and we review your Irish employment history and submit the claim to Revenue as your appointed Irish tax agent. Revenue issues the refund by electronic funds transfer to any IBAN you specify — including foreign bank accounts — or by cheque posted to your international address.
Qualifying Expenses From Irish Employment
Medical expenses incurred during your period of Irish employment are claimable as part of the emigrant tax back submission. Flat-rate employment expense allowances (profession-specific, no receipts) for the years you worked in Ireland are also claimable. Remote working relief applies to any period you worked from home while employed in Ireland. These are added to the credit-based refund for a comprehensive four-year submission.
Tax Residency Considerations
For the year you left Ireland, your tax liability is calculated on your Irish income only (unless you had other Irish income sources such as rental income from a property retained in Ireland). The split-year treatment means you are taxed on Irish income from 1 January to the date of departure. Any tax collected on income during the Irish period in excess of your actual Irish liability (after Irish credits) is refundable. MyTaxRebate handles the split-year calculation as part of every emigrant claim.

Start My Claim →Real-World Scenarios
Scenario 1: Irish Worker in Australia
An Irish nurse emigrated to Australia in September 2023. She had worked in Ireland from January to September 2023. Her employer deducted PAYE as if she would work the full year. The credits for October, November, and December 2023 were unused. She also had €1,400 in qualifying medical expenses and her nursing flat-rate allowance for 2022 and 2023. MyTaxRebate submitted remotely. Revenue issued a refund of €2,180 by electronic transfer to her Australian bank account.
Scenario 2: Non-Irish Worker Returned Home
A Polish construction worker worked in Ireland from 2021 to June 2024, then returned to Poland. He had not claimed his flat-rate construction expense allowance for 2022, 2023, or 2024. He also had unused credits for the second half of 2024. MyTaxRebate reviewed all available years (2022, 2023, and 2024 — he had 2021 records but that year was time-barred). Total refund: €1,870, transferred to his Polish bank account by Revenue.
Scenario 3: Worker in the UK With Emergency Tax History
An Irish accountant moved to London in 2023 after working in Dublin for three years. In 2022, he had been placed on emergency tax for two months when he changed Dublin employers. He had never claimed the emergency tax refund or his accounting flat-rate allowance. MyTaxRebate recovered €1,540 across 2022 and 2023 — the emergency tax overpayment, two years of flat-rate allowance, and €600 in qualifying medical expenses. Revenue issued payment to his UK bank account.
Common Mistakes to Avoid
- Missing the four-year deadline while abroad: Workers who emigrated in 2022 and have not yet claimed should note the 2022 deadline closes 31 December 2026. Emigrant workers frequently forget about Irish tax entitlements until years have passed — act before years expire permanently.
- Assuming you cannot claim without returning to Ireland: You do not need to return to Ireland, visit a Revenue office, or contact Revenue directly. MyTaxRebate manages the entire claim process remotely on your behalf.
- Not claiming for all years worked in Ireland: Many emigrant workers only claim for the year they left and miss prior years when they were also owed refunds from unclaimed reliefs. Always review all four available years simultaneously.
- Not providing a foreign IBAN for payment: Revenue can issue refunds by EFT to foreign bank accounts. Ensure your current bank account details are provided with your application to receive the fastest payment route.
- Leaving documents behind in Ireland: P45s, payslips, and medical receipts can often be replaced. Employer payroll records are available to MyTaxRebate as your appointed agent through Revenue’s records. Missing documents are rarely a barrier to a successful claim.
When This Does Not Apply
- Workers who only worked in Ireland on a non-PAYE basis: Non-residents who worked as contractors under the Relevant Contracts Tax (RCT) system have a different refund process from PAYE workers.
- Tax years outside the four-year window: Under s.865 TCA 1997, Irish tax years before 2022 cannot be claimed in 2025. Workers who left Ireland in 2018 or 2019 and have not yet claimed have no remaining entitlement for those years.
- Workers with Irish rental income: If you retained a rental property in Ireland after emigrating, you have annual Irish income tax filing obligations as a non-resident landlord. MyTaxRebate advises on the interaction between rental tax obligations and PAYE refund entitlements.
- Double taxation treaty implications: Workers who are now tax resident in a country with a double taxation agreement with Ireland should confirm their treaty position before submitting a claim. In most cases, the treaty does not prevent a refund of Irish PAYE overpayment.

Frequently Asked Questions
Can I claim Irish tax back after leaving Ireland?
Yes. Under s.865 TCA 1997, any person who paid Irish income tax through the PAYE system can claim a refund of any overpayment within four years, regardless of where they now live. Irish workers who emigrated to Australia, the UK, the US, Europe, or anywhere else can claim remotely through MyTaxRebate without returning to Ireland. In 2025, the four available years are 2022, 2023, 2024, and 2025.
How do I claim Irish tax back from abroad?
Complete MyTaxRebate’s online application from wherever you are located. Provide scanned copies of your payslips, P45, and any expense documentation from your Irish employment. We review your Irish employment history and tax position for all available years, calculate the refund, and submit directly to Revenue as your appointed Irish tax agent. Revenue issues the refund by electronic transfer to your foreign bank account or by cheque posted to your international address.
How much Irish tax can I claim back after leaving?
The amount depends on when in the year you left Ireland and what qualifying expenses and reliefs apply. Workers who left early in a calendar year (January–April) typically have larger unused credit balances and therefore larger refunds. Workers with additional qualifying expenses (medical, flat-rate allowances) recover more. The average refund for an emigrant worker processed by MyTaxRebate is approximately €1,200, though amounts vary significantly based on individual circumstances.
How long do I have to claim Irish tax back after emigrating?
Under s.865 TCA 1997, you have four years from the end of the relevant Irish tax year to claim a refund. In 2025, the available years are 2022, 2023, 2024, and 2025. The 2022 deadline closes on 31 December 2026. Workers who emigrated in 2022 or 2023 and have not yet claimed should act immediately to preserve their entitlement for the earliest years. There are no extensions to the four-year rule.
Can Revenue pay my Irish tax refund to a foreign bank account?
Yes. Revenue can issue tax refunds by electronic funds transfer (EFT) to any bank account with a valid IBAN, including bank accounts in Ireland, the UK, Europe, Australia, and other countries. When completing your application with MyTaxRebate, provide your current bank account IBAN to ensure the refund is transferred directly. Revenue can also issue cheques to international addresses if no IBAN is provided, though this is slower.
