Quick answer
- PAYE is Income Tax calculated with rate bands and tax credits.
- USC is a separate charge on gross income with its own exemption, bands and reduced-rate rules.
- PRSI is social insurance based on contribution class and earnings rules, and the employer contribution is not deducted from your pay.
- A qualifying employee pension contribution can reduce Income Tax but does not receive employee USC or PRSI relief.

The order used for a take-home-pay estimate
Worked €50,000 employee example
This full-year illustration uses a single employee with a €44,000 PAYE band, €4,000 credits, standard 2026 USC, Class A employee PRSI and no pension or other deduction. PRSI is blended for the scheduled 4.20% rate through September and 4.35% from 1 October.
| Annual item | Estimated amount | Why it differs |
|---|---|---|
| Gross salary | €50,000.00 | Starting amount |
| PAYE | €7,200.00 | 20%/40% bands less €4,000 credits |
| USC | €1,032.82 | Separate 2026 USC bands |
| Employee PRSI | €2,118.75 | Illustrative blended 2026 Class A rate |
| Estimated net before other deductions | €39,648.43 | Gross less the three statutory deductions |
| Average monthly net | €3,304.04 | Annual average, not an exact payslip promise |
Why pension treatment differs across the three deductions
Revenue grants qualifying employee pension contributions Income Tax relief at the employee’s marginal rate, subject to age-related and earnings limits. Revenue also states that employee contributions do not receive USC or PRSI relief. This is why adding a pension can reduce PAYE while USC and PRSI remain higher than someone might expect from the new taxable-Income-Tax figure.
| Contribution effect | PAYE | USC | Employee PRSI |
|---|---|---|---|
| Qualifying employee pension contribution | Income Tax relief may apply | No employee-contribution relief | No employee-contribution relief |
