Why is my tax so high?
If your take-home pay is lower than expected, the cause is usually somewhere on your payslip: PAYE, USC, PRSI, pension deductions, emergency tax or missing credits.
Common reasons your deductions look high
| Reason | What to check |
|---|---|
| Emergency tax | Your job may not be registered correctly with Revenue yet. |
| Missing tax credits | Your Tax Credit Certificate may not show all credits you are entitled to. |
| Second job | Your credits and rate band may be split between employments. |
| USC and PRSI | These are separate from PAYE and can make total deductions look bigger. |
| Pension or benefit deductions | Pension, health insurance or other agreed deductions can reduce net pay. |
| Bonus or overtime | A higher pay period can push more income into higher tax/USC bands for that period. |
Start with your payslip
Look at whether the deduction is PAYE, USC, PRSI, pension or something else. Your payslip should itemise deductions, so do not treat the total deduction as one single “tax” number.

Check Revenue myAccount
If PAYE looks too high, check your job, tax credits and Tax Credit Certificate in Revenue myAccount. Revenue payroll details are what your employer uses to calculate PAYE and USC.

Could it be emergency tax?
Emergency tax usually happens when Revenue does not yet have the correct information about your employment. Once corrected, overpaid PAYE is often refunded through payroll.

Could it be USC or PRSI?
PAYE is only one deduction. USC and PRSI are separate deductions with different rules. If you add them together, your total deductions can look much higher than your income tax alone.
