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 PRSI at 4.15%.
Tax credits rather than allowances reduce the bill: a single PAYE worker receives roughly €4,000 in combined personal and employee credits, deducted directly from tax owed.
Formula & worked example
USC = banded 0.5% / 2% / 3% / 8%
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 €1,196 and PRSI €2,283. Monthly take-home lands near €3,389.
