How to File a Tax Return
in Ireland (2026)
Who needs to file, what you can claim, how to use Revenue's myAccount, and how to get a refund.
Why many Irish taxpayers are owed a refund
Ireland's PAYE system deducts income tax, USC, and PRSI from your salary automatically each pay period. While Revenue tries to apply the correct credits and rates, many taxpayers end up overpaying during the year and are entitled to a refund they never claim.
The most common reasons for overpayment include: medical expenses that were never submitted, flat-rate employment expenses that apply to your occupation, working from home on days that qualify for e-worker relief, a change in employment or salary mid-year, or tax credits you are entitled to but that are not yet on your Tax Credit Certificate. Revenue will not automatically issue refunds for these; you need to request a review.
The good news: Revenue allows you to look back four years. That means in 2026, you can still claim for 2025, 2024, 2023, and 2022. Each year takes around ten minutes to review online via Revenue's myAccount, and refunds are usually processed within five business days of submission.
Who needs to file a tax return in Ireland?
PAYE employees — Form 12 (Annual Tax Review)
Most PAYE employees are not legally required to file a tax return every year, because Revenue administers their tax through the payroll system. However, you should file a Form 12 (or request a balancing statement through myAccount) if any of the following apply:
- You have qualifying medical expenses to claim
- You work from home and want to claim e-worker relief
- You have credits on your Tax Credit Certificate that were not in place for the full year
- You changed jobs and your new employer's payroll did not carry forward your credits correctly
- You had a period of unemployment during the year
- You paid tuition fees for an approved course
- You have flat-rate employment expenses applicable to your job
- You want to claim the Rent Tax Credit (if not done via employer)
Self-employed, company directors, and those with non-PAYE income — Form 11
You are required to file a Form 11 self-assessment return if you are self-employed, a proprietary company director (holding more than 15% of shares), or if you have non-PAYE income above €5,000 per year. This includes income from:
- Rental property (even a single room in some cases)
- Freelance or consultancy work alongside employment
- Dividends, foreign income, or investment returns
- Profit from the sale of assets (Capital Gains Tax)
Form 11 must be filed through Revenue Online Service (ROS) at ros.ie. This guide focuses primarily on the PAYE Form 12 process via myAccount.
Setting up Revenue's myAccount
Revenue's myAccount portal at myaccount.revenue.ie is where PAYE employees manage their tax online — viewing credits, submitting returns, requesting refunds, and downloading balancing statements. If you have not yet registered, you will need:
- Your PPS number
- Your date of birth
- Your mobile phone number (for the activation code)
- Your Eircode (used to verify your address)
Registration takes about five minutes. Revenue sends a six-digit activation code to your mobile number via SMS. Once activated, you have immediate access to your full PAYE tax history, your current Tax Credit Certificate, and all online claiming features.
If you already have a myAccount login but have not used it in a while, you may need to go through a security step-up using your mobile number. Revenue introduced two-factor authentication for all myAccount users in recent years.
How to file your tax review — step by step
Log in to myAccount
Go to myaccount.revenue.ie and sign in with your PPS number and password. Complete the two-factor authentication step if prompted.
Go to "Review your tax"
From the myAccount homepage, click on "Review your tax" under the PAYE Services section. You will see a list of tax years available to review — select the year you want to start with. Revenue recommends working through the oldest year first.
Confirm or update your income details
Revenue will pre-populate your income from your employer(s) based on payroll submissions. Check the figures are correct. If you had multiple employers during the year, all should appear. If something is missing, you can add it manually. Include any non-PAYE income such as rental income (which may require a Form 11 instead).
Add credits and reliefs
This is the key step. You will be presented with a list of credits and reliefs to claim. Add everything that applies to you — medical expenses, working from home, flat-rate expenses, tuition fees, and any other qualifying amounts. See the section below for a full list of what you can claim.
Submit the return
Review the summary screen showing your calculated tax liability versus what was actually deducted from your pay. If you overpaid, the difference is your refund. Click "Submit" to send your return to Revenue. You will receive an on-screen confirmation and a reference number.
Receive your End of Year Statement and refund
Revenue processes the return and issues an End of Year Statement (formerly called the P21 Balancing Statement). If you are due a refund, Revenue will pay it directly to your bank account, usually within five working days of processing. If you have not added your bank details to myAccount, do so in the "Manage bank accounts" section before submitting.
What PAYE employees can claim on a tax return
Health expenses — 20% tax relief
You can claim income tax relief at the standard rate (20%) on qualifying health expenses paid for yourself or another person. You do not need to have a medical card to claim. Expenses must not be reimbursed by health insurance, your employer, or any other source. Qualifying expenses include:
- GP and doctor consultations
- Hospital charges and overnight stays
- Specialist and consultant fees
- Prescribed medicines and drugs
- Physiotherapy and speech therapy (if prescribed by a doctor)
- Diagnostic tests and scans
- Non-routine dental treatments (orthodontics, crowns, bridges — but not routine fillings, cleaning, or extractions)
- Hearing aids
- Nursing home fees for a dependent relative
Keep all receipts. Revenue may request them during an audit. Claim via the "Health expenses" section in myAccount under "Review your tax". There is no minimum amount — even a single GP visit is claimable.
Remote working (e-worker) relief
If you worked from home on a regular or agreed basis during the tax year, not just occasionally, you may be entitled to e-worker relief. You can claim 30% of your actual costs for heat, electricity, and broadband, apportioned to the number of days you worked from home versus your total working days in the year.
For example: if you worked from home 120 days out of 220 working days, and your annual utility bills were €2,400, your claimable amount is approximately €2,400 × (120 ÷ 220) × 30% = €393. Tax relief at 20% or 40% applies to this figure. Claim through the "Remote working relief" section in myAccount. You will need your actual utility costs for the year.
Note: if your employer already paid you the tax-free €3.20 per day working from home allowance, you cannot also claim e-worker relief for those days, but you can claim for any unreimbursed portion.
Flat-rate employment expenses
Revenue has agreed flat-rate expense deductions with many occupational groups to cover the cost of tools, uniforms, and equipment that employees must purchase themselves and are not reimbursed for. Once claimed, this credit is usually applied automatically to your Tax Credit Certificate each year thereafter.
Common examples include:
| Occupation | Annual Flat-Rate Deduction |
|---|---|
| Nurses and midwives (registered) | €733 |
| National school teachers | €518 |
| Secondary school teachers | €518 |
| Journalists / reporters | €317 |
| Engineers (civil, structural, etc.) | €523 |
| Airline pilots and cabin crew | €64–€1,022 (varies) |
| Bar / hotel workers | €80 |
The full list of flat-rate expense amounts is published on Revenue.ie. Search for "flat-rate expenses" in the Revenue website to find your occupation and the applicable amount. Claim through myAccount under "Add a credit / relief".
Tuition fees — 20% relief
Tax relief at 20% is available on tuition fees for approved third-level courses in Ireland and some EU countries. The relief applies to undergraduate and postgraduate courses. The first €3,000 of fees paid is disregarded (the "excess" threshold), meaning relief only applies to fees above €3,000. The maximum fees eligible for relief is €7,000 per course per academic year. Part-time courses and distance learning may also qualify if the college is an approved institution.
You can claim tuition fees paid for yourself, your spouse or civil partner, or a dependent child. Keep your receipts from the college or university. Claim via myAccount under "Tuition fees" in the review section.
Rent Tax Credit (if not already applied)
If you are a private tenant and have not already added the Rent Tax Credit to your Tax Credit Certificate, you can claim it through the tax review process for the current year and the three previous years (subject to the credit existing in those years, as it was first introduced for 2022). For 2026, the credit is worth €1,000 for a single person and €2,000 for a jointly assessed married couple. You will need the Residential Tenancies Board (RTB) registration number of your rental property, which your landlord is required to provide.
Pension contributions (AVC / PRSA)
If you made Additional Voluntary Contributions (AVCs) to an occupational pension scheme, or contributions to a Personal Retirement Savings Account (PRSA) that were not processed through your employer's payroll, you will need to claim the tax relief through your tax return. Include the total contributions made during the tax year under "Pension contributions" in the review. Relief is given at your marginal tax rate, subject to the age-related percentage limits (15%–40% of earnings up to €115,000).
Permanent Health Insurance (PHI) premiums
Premiums paid for an approved Permanent Health Insurance (income protection) policy are eligible for income tax relief at your marginal rate, subject to a cap of 10% of your total income. If your employer deducts PHI premiums from your salary before tax, the relief is already applied. If you pay them personally, claim via your tax return. Note: standard health insurance (VHI, Irish Life Health, Laya) is treated differently; BIK rules apply rather than a direct relief.
The four-year rule — how far back you can claim
Under Revenue rules, you can claim a tax refund for any of the four preceding tax years. In 2026, this means you can review and claim for 2025, 2024, 2023, and 2022. Claims for years prior to 2022 are no longer accepted — the window has closed.
Each tax year must be reviewed separately in myAccount. If you have four years of unclaimed medical expenses, for example, you would submit four separate reviews. Revenue processes each independently and will issue a separate refund for each year.
| Tax Year | Claimable in 2026? | Deadline |
|---|---|---|
| 2025 | Yes | 31 Dec 2029 |
| 2024 | Yes | 31 Dec 2028 |
| 2023 | Yes | 31 Dec 2027 |
| 2022 | Yes | 31 Dec 2026 |
| 2021 or earlier | No — window closed | — |
Note that 2022 claims must be filed before 31 December 2026 — if you have any unclaimed expenses for 2022, do not leave it until 2027.
Tax return deadlines
PAYE employees (Form 12)
There is no strict annual deadline for PAYE employees requesting a balancing statement via Form 12. You can submit a review for any year within the four-year window at any time. However, if you have a liability for a given year (i.e., you underpaid), Revenue will calculate interest on late payment, so it is worth reviewing promptly at the start of each new year.
Self-assessed taxpayers (Form 11)
| Filing method | Deadline |
|---|---|
| Paper return (Form 11) | 31 October each year |
| Online via ROS (Revenue Online Service) | Mid-November (extended deadline) |
| Preliminary tax payment | 31 October each year |
Self-assessed taxpayers must also pay preliminary tax (an advance payment of at least 90% of the current year's liability) by 31 October. Failure to do so results in interest charges. Revenue sends automated reminders via ROS inbox in advance of the deadline.
What happens after you file
If you are owed a refund
Revenue issues your End of Year Statement (Balancing Statement) within five working days of processing your return. If you have a bank account linked to myAccount, the refund is paid directly to that account within the same period. If no bank account is on file, Revenue issues a cheque to your registered address. To add or update your bank account, go to "Manage bank accounts" within myAccount before submitting your return.
If you have underpaid tax
If your review shows you underpaid tax during the year, Revenue will issue a demand for the balance. For amounts under a certain threshold, Revenue will typically collect the underpayment by reducing your Tax Credit Certificate for the following year, spreading the repayment across your remaining pay periods rather than issuing an immediate demand. For larger underpayments, or if you no longer have PAYE income, a direct payment arrangement will be needed.
Keeping your Tax Credit Certificate updated
Once you claim a credit or relief through a tax review, Revenue usually adds it to your Tax Credit Certificate for future years automatically. For example, flat-rate expenses or the Rent Tax Credit. This means your employer's payroll will apply the benefit going forward without you having to re-claim each year. Check your Tax Credit Certificate in myAccount at the start of each year to confirm it reflects everything you are entitled to.
