The most common reasons for an Irish tax refund

1. Emergency tax

If you started a new job and your employer did not have your PPS number registered against the new employment, you were probably taxed at the emergency rate. The first month, you receive a credit of one twelfth of the standard credit. From month two onwards everything is taxed at 40% with no credits. A four week emergency tax episode on a 3,000 euro monthly gross can leave you 700 to 900 euro overpaid.

2. Missed tax credits

Credits commonly forgotten include:

  • Single Person Child Carer Credit (1,900 euro).
  • Home Carer Tax Credit (1,800 euro).
  • Rent Tax Credit (1,000 euro single, 2,000 euro jointly assessed couple).
  • Incapacitated Child Tax Credit (3,500 euro).
  • Dependent Relative Tax Credit (305 euro).

3. Medical expenses at 20% standard rate relief

Most non-routine medical expenses qualify for 20% relief. Doctor visits, consultant fees, prescribed medicines, physiotherapy, and IVF treatment all count. Routine dental and ophthalmic care does not, but specialist dental work claimed via Med 2 does. Spend 1,000 euro in qualifying fees and you can reclaim 200 euro.

4. Work from home relief

Remote workers can claim 30% of allowable utility costs (electricity, heat, broadband) apportioned for the days worked from home. The relief flows through your tax return rather than payroll.

5. Flat rate expenses

Revenue maintains a list of flat rate expense allowances by occupation. Nurses, teachers, shop assistants, hospitality workers, and many trades all have a fixed annual deduction. Most are between 100 and 750 euro a year, and you can claim retrospectively for four tax years.

6. Tuition fees and college costs

Approved third level tuition fees over 3,000 euro per academic year qualify for 20% relief, capped at 7,000 euro per course.

Worked example

Aoife earned 42,000 euro in 2026. She started a new job in March and was emergency taxed for two months. She paid 800 euro in physio and dental work. She also forgot to claim the 1,000 euro Rent Tax Credit. After running her figures:

  • Emergency tax overpayment: 540 euro.
  • Medical relief: 160 euro.
  • Rent Tax Credit: 1,000 euro.
  • Total potential refund: roughly 1,700 euro.

How to claim

You claim through Revenue myAccount by:

  1. Filing an income tax return (Form 12) for the relevant year.
  2. Adding receipts for medical expenses under Manage Your Tax.
  3. Requesting a Statement of Liability (P21) once the return is filed.

You can claim back four years (so 2022, 2023, 2024, and 2025 are all open during 2026). Refunds usually land in your bank account within five working days of acceptance.
