How this Irish take-home pay estimate works
The calculator applies the lower income-tax rate to salary up to the band you enter. It applies the higher rate above that band, then subtracts your entered tax credits without allowing income tax to fall below zero. USC and PRSI are estimated as simple percentages of gross salary. Annual net pay is gross salary less those three deductions, divided by 12 for the monthly figure.
Why your payslip can differ from this estimate
Real Irish payroll calculations can include several USC bands, PRSI classes and thresholds, pension contributions, benefits in kind, reliefs, exemptions, cumulative tax treatment, joint assessment and employer-specific pay timing. This calculator deliberately does not imitate those rules with unverified data.
Where to find current Irish tax rates and credits
Use Revenue's current income-tax calculation guidance, Universal Social Charge guidance and PRSI guidance. Revenue is the primary authority for the inputs. Check the pages at the time you calculate because rates, bands and eligibility can change.
What this salary calculator does not tell you
It does not determine your tax liability, reproduce a payslip, assess eligibility for a credit or recommend pension contributions. Use it to understand the relationship between assumptions and estimated net pay. For an individual calculation, use current official services or appropriately qualified advice.
Illustrative estimate only. It is not tax, payroll or financial advice.
