How Your Tax is Calculated
Irish tax calculation combines income tax (at 20%/40%), USC (at progressive rates), and PRSI (at 4.35%). Understanding how these interact is crucial for tax planning.
Calculate Gross Income
Sum all income: employment income (salary, bonuses, BIK), self-employment profits, rental income, pension income, investment income (dividends, interest). This is your total income before any deductions.
Apply USC
USC applies to gross income (before tax credits, but after pension contributions). Calculate USC using the progressive bands: 0.5% on first €12,012, 2% on next €16,688 (to €28,700), 3% on next €41,344 (to €70,044), and 8% on balance. If exempt (income ≤€13,000), skip this step.
Calculate PRSI
PRSI at 4.35% (from Oct 2026) on all gross employment income. Exempt if earning ≤€352/week. Self-employed pay 4.35% on business profits (minimum €650). PRSI is separate from income tax and USC.
Determine Income Tax Band
Single: €44,000 at 20%, balance at 40%. Married one earner: €53,000 at 20%, balance at 40%. Married two earners: standard band transferable up to €88,000 combined (max €44,000 per person). Single parent: €48,000 at 20%.
Calculate Income Tax
Apply rates to gross income: multiply income in 20% band by 20%, multiply income in 40% band by 40%. Add together for gross income tax before credits.
Deduct Tax Credits
Subtract total tax credits: Personal (€2,000) + Employee/Earned Income (€2,000) + any others you qualify for (rent, age, dependent, etc.). Credits reduce tax euro-for-euro. Cannot go negative.
Total Tax Liability
Sum of: Income Tax (after credits) + USC + PRSI = total annual tax. For PAYE employees, deducted monthly by employer. Self-employed pay via preliminary tax (Oct 31) and balance (Oct 31 following year).
Example Calculation (€60,000 annual salary - Single PAYE worker)
This assumes full year at October 2026 PRSI rate for simplicity. Actual 2026 calculation would prorate 4.2% and 4.35% rates. Married couples and those with additional credits will pay less tax.

PRSI - Pay Related Social Insurance
PRSI (Pay Related Social Insurance) is Ireland's social security system funding healthcare, state pensions, maternity/paternity leave, jobseeker's benefits, and disability payments. Contributions are mandatory for all workers earning above minimum thresholds.
02Universal Social Charge (USC)
The Universal Social Charge is applied to gross income before any tax credits or deductions (except pension contributions and certain capital allowances). USC replaced the income levy and health levy in 2011 and applies separately from income tax.
03Tax Credits & Reliefs
Tax credits reduce your income tax liability euro-for-euro. Unlike deductions (which reduce taxable income), credits directly reduce the tax you owe. Ireland's tax credit system is generous and can significantly reduce effective tax rates.
05Capital Gains Tax & Investment Income
Capital gains and investment income are taxed separately from employment income. Ireland has specific rules for different asset types including property, shares, and cryptocurrency.
06Special Assignee Relief Programme (SARP)
SARP is Ireland's expat tax regime designed to attract highly-skilled international talent. It provides significant income tax relief for qualifying employees assigned to work in Ireland from abroad.
