How Ireland income tax works
Ireland uses a progressive income tax with a top rate of 40.00%. Only the income inside each band is taxed at that band's rate.
20% standard rate to €42,000, then 40%. Tax credits and USC are separate and reduce the net rate.
Because of the bands, your effective rate — total tax divided by income — is always lower than your top marginal rate.
Take-home pay in Ireland
Your take-home is income minus income tax. This calculator shows that figure, but bear in mind social-security or national-insurance contributions are usually deducted separately and are not included here.
Tax credits, allowances and reliefs can also lower the amount you actually pay, so treat this as a baseline estimate.
What this does not include
This estimate covers Ireland income tax only. Social contributions, surcharges, local taxes and personal credits can move your real bill up or down.
Treat it as a planning figure and verify with the Revenue Commissioners (revenue.ie) or a local tax adviser.
