FAQ

How is retro pay taxed in Ireland?

Retro pay is added to your current pay period and taxed at your marginal rate — up to 52% (40% PAYE + 8% USC above €70,044 + 4% PRSI). It is treated as income in the period it's paid, not the period it relates to.

Will retro pay push me into a higher tax bracket?

Yes, if the lump sum is large. A €10,000 retro payment on a €60,000 salary pushes that month into the USC 8% band. On a cumulative payroll basis, the overpayment auto-corrects over the rest of the year.

Can I get a refund if too much tax was deducted from retro pay?

If payroll is on a cumulative basis, the overpaid tax corrects automatically in future payslips. On Week 1 basis, you may need to file a year-end tax return.

Retro pay tax treatment depends on your payroll basis. These are 2026 estimates for planning. Check your payslip for exact deductions.
