Can I get a tax refund if my holiday pay payout was taxed heavily?
It depends on your overall yearly position. A one-off payment can create a high deduction in one payslip, but the final year result can differ. This page provides scenario guidance only.
Why can holiday pay payout look like it was taxed at a high rate?
A payout can push the payslip into higher marginal PAYE and USC bands for that period. PRSI may also apply depending on PRSI class and payroll setup.
How can I estimate whether I might be overpaying?
Use annual scenarios to compare your expected full-year net pay. Avoid judging solely from a single payslip. If you need accuracy, confirm your year-to-date details and credits.
