Claim tax back · Ireland · 2026

There's a good chance Revenue owes you money

Most PAYE workers in Ireland overpay tax at some point — through unclaimed credits, medical bills, rent, remote working or emergency tax. You can claim it back for the last four years, free, through Revenue. Here's exactly how, and what to look for.

What you can claim back

Medical & dental expenses

Relief at 20% on non-routine medical and dental costs (use the Med 2 form for dental). Includes GP fees, prescriptions, consultants and more.

Rent tax credit

Up to €1,000 (single) or €2,000 (couple) a year for private renters, claimable for 2022 onward.

Remote-working relief

30% of the cost of electricity, heating and broadband for the days you worked from home.

Flat-rate expenses

A set deduction for many occupations — nurses, teachers, trades and others — with no receipts needed.

Tuition fees

Relief at 20% on qualifying third-level course fees, above a disregarded amount.

Emergency tax

If you were taxed on an emergency basis when starting a job, you can reclaim the overpayment once your details are sorted.

How to claim, step by step

  • Sign in to Revenue's myAccount (register first if you have not used it).
  • Choose "Review your tax" for the year you want to check.
  • Request a Statement of Liability — it shows whether you overpaid.
  • Add any credits or expenses you missed (medical, rent, remote working).
  • Revenue pays any refund straight to your bank account, usually within days.

The four-year rule

You can claim a refund for the current year and the previous four. After that the money is gone, so it pays to review each year — a single missed rent credit or set of medical bills can add up to hundreds of euro.

Before you claim, know your numbers

Check what you should be taking home in the first place on the take-home calculator, and read up on the credits you're entitled to — many refunds come down to credits people never claimed.

On a part-time or low income, or juggling more than one job? See how part-time work is taxed, tax on a second job, and tax for students — these are where overpayments most often build up.

Claiming tax back — common questions

How do I claim my tax back in Ireland?
Sign in to Revenue's myAccount, choose "Review your tax" for the year, and request a Statement of Liability. Add any credits or expenses you missed — medical costs, rent, remote-working relief — and Revenue refunds any overpayment to your bank account. It is free and usually takes a few days to a couple of weeks.
How far back can I claim tax in Ireland?
Four years. Under the four-year rule (Section 865 of the Taxes Consolidation Act 1997), you can claim a refund for the current year and the previous four. After that, the right to a refund is lost, so it is worth reviewing each year.
How do I check if Revenue owes me money?
Request a Statement of Liability in myAccount for each of the last four years. It compares the tax you paid against what you owed; if you overpaid, the statement shows the refund due. Common causes are unclaimed credits, emergency tax, or expenses you never claimed.
What can I claim tax back on?
Common reliefs include non-routine medical and dental expenses (20%), the rent tax credit, remote-working relief on electricity, heating and broadband, tuition fees, flat-rate work expenses for your occupation, and overpaid or emergency tax. Income protection premiums also get relief at your marginal rate.
How long does a tax refund take?
Once you submit the request through myAccount, refunds are typically processed within five working days to about three weeks, paid straight to your bank account. Paper claims take longer.
