Income Tax Calculator Ireland
Estimate your 2026 Irish PAYE income tax, USC, PRSI and net take-home pay. Model pension contributions, extra tax credits, self-employed income and auto-enrolment in one place.
How It Works
This calculator follows the same broad sequence used in Irish payroll estimates: taxable pay is worked out first, income tax is calculated through the 20% and 40% bands, tax credits reduce the PAYE bill, and then USC, PRSI and optional auto-enrolment are shown separately.

This calculator is an estimate only. It does not read your Revenue tax credit certificate and it does not cover every credit, relief, PRSI subclass, benefit-in-kind, emergency-tax basis, rental-income rule or self-employed circumstance. Pension, USC, PRSI and auto-enrolment treatment can vary by payroll setup. Use the result for planning and confirm important decisions with Revenue, payroll or a qualified tax adviser.
