How this is calculated
Many people in Ireland overpay PAYE and never claim it back. It usually happens when you're on emergency tax before Revenue has your details, when you leave a job partway through the year, or when you arrive mid-year and don't use a full year's tax credits. If you were on the cumulative basis from day one there's rarely a PAYE refund, but emergency or Week 1 taxing often leaves money owed. You can claim back up to four years. The estimator asks the one question that matters — whether your employer had your details from the start — and reconciles income tax and USC.
Questions people ask
How do I claim a tax refund in Ireland?
File an income tax return (Form 12) through Revenue's myAccount, or ask us to do it. You can go back four tax years.
How do I know if I paid emergency tax?
Your payslip shows it — look for 'Week 1', 'Month 1' or 'emergency' basis, or a flat high deduction with no credits applied.
How far back can I claim?
Four tax years. Anything older is out of time.
Is PRSI refunded too?
Not in this estimate — PRSI is due per pay period and isn't reconciled at year end the way income tax and USC are.
