Tax refunds
Tax refunds in Ireland: am I due tax back, and how do I claim it?
A refund is Revenue repaying tax you overpaid. Most PAYE refunds come from credits and reliefs nobody claimed, a job change, or a year on the wrong basis. You claim for free in myAccount, back four years.
No guaranteed refunds

Emergency tax
Why a new job gets taxed at 40% and how the excess comes back.
Previous years
The four-year rule: 2022 claims close on 31 December 2026.
Common reasons people overpay
- Credits never claimed: Rent Tax Credit, health expenses, remote working, tuition fees, dependent relative.
- Starting a job on emergency tax or a week 1 basis and never having the year reviewed.
- Working only part of the year, so annual credits were not fully used.
- Two employments with the rate band and credits split badly.
- Flat rate expenses for your occupation not added to your certificate.
Income Tax and USC are refunded separately
Your Statement of Liability shows Income Tax and USC on separate lines. A credit like the Rent Tax Credit only reduces Income Tax; it cannot refund USC. USC overpayments arise from their own band rules, for example when income is below the exemption threshold. PRSI is never refunded through this process.
Start here
- Run the relief finder for the year.
- Use the refund estimator to see whether tax paid exceeds tax due.
- Follow the PAYE return walkthrough and submit in myAccount.
