What is the Ireland Income Tax?
Ireland has just two income tax rates — 20% on the standard rate band and 40% above — but adds the Universal Social Charge (0.5% to 8% in bands) and employee PRSI, which rose to 4.2% on 1 October 2025.
Tax credits rather than allowances reduce the bill: for 2026 a single PAYE worker receives a €2,000 personal credit plus a €2,000 employee credit — €4,000 in total — deducted directly from tax owed.
Formula & worked example
USC 2026 = 0.5% on the first €12,012, 2% on the next €16,688, 3% on the next €41,344, 8% on the balance
Net = Gross − pension − tax − USC − PRSI
Worked example: €55,000 gross, single, with a 5% pension contribution. Taxable pay is €52,250: €44,000 at 20% and €8,250 at 40% = €12,100, less €4,000 credits = €8,100. USC is about €1,183 and PRSI €2,310. Monthly take-home lands near €3,388.
