Summary
Ireland uses a PAYE (Pay As You Earn) system where employers deduct income tax, Universal Social Charge (USC), and Pay Related Social Insurance (PRSI) from each payslip. Ireland’s income tax has just two brackets (20% and 40%), but the effective tax burden is reduced by generous tax credits - the personal credit and PAYE credit together mean the first portion of income is effectively tax-free.
How it works
Your take-home pay is your gross salary minus three deductions:
- Income tax - two brackets (20% standard rate, 40% higher rate), reduced by tax credits
- Universal Social Charge (USC) - four progressive bands from 0.5% to 8%
- PRSI (Pay Related Social Insurance) - a flat 4.1% on all earnings (Class A employee, 2025)
Tax credits reduce the income tax liability directly (euro-for-euro), not the taxable income. The two main credits for a single PAYE worker total €4,000, effectively making the first €20,000 of income tax-free at the 20% rate.
Income Tax Bands (2025)
Ireland’s income tax for a single person in 2025:
| Taxable income | Rate |
|---|---|
| Up to €44,000 | 20% (standard rate) |
| Above €44,000 | 40% (higher rate) |
Tax Credits
Tax credits reduce your income tax bill directly:
| Credit | Amount (2025) |
|---|---|
| Personal Tax Credit (single) | €2,000 |
| PAYE Employee Tax Credit | €2,000 |
| Total for single PAYE worker | €4,000 |
Net income tax = max(0, gross tax - tax credits). With €4,000 in credits, a single PAYE worker pays no income tax on the first €20,000 of income (since €20,000 x 20% = €4,000).
Universal Social Charge (USC)
USC is a separate charge on gross income with four bands:
| Income band | USC rate |
|---|---|
| Up to €12,012 | 0.5% |
| €12,013 - €25,760 | 2% |
| €25,761 - €70,044 | 4% |
| Above €70,044 | 8% |
USC applies to total income - there is no tax-free threshold (though individuals earning €13,000 or less per year are exempt from USC entirely).
PRSI (Pay Related Social Insurance)
For Class A employees (most PAYE workers) in 2025:
| Component | Rate |
|---|---|
| Employee PRSI | 4.1% |
PRSI at 4.1% applies to all earnings with no upper ceiling. There is a weekly earnings threshold of €352 below which no PRSI is payable, and a PRSI credit that tapers for weekly earnings between €352 and €424.
The formula
Where
Worked example
EUR 45,000 gross annual salary, single PAYE worker
Income tax: first EUR 44,000 at 20%
= EUR 8,800
Income tax: remaining EUR 1,000 at 40%
= EUR 400
Gross income tax
= EUR 9,200
Tax credits (personal + PAYE)
= EUR 4,000
Net income tax
= EUR 5,200
USC band 1: first EUR 12,012 at 0.5%
= EUR 60.06
USC band 2: EUR 12,013 - EUR 25,760 at 2%
= EUR 274.96
USC band 3: EUR 25,761 - EUR 45,000 at 4%
= EUR 769.60
Total USC
= EUR 1,104.62
PRSI (4.1% of gross)
= EUR 1,845
Total deductions
= EUR 8,149.62
Result
Take-home pay = EUR 45,000 - EUR 8,149.62 = EUR 36,850.38/year (EUR 3,070.87/month)
Assumptions & limitations
- Uses 2025 rates for income tax, USC, and PRSI
- Assumes a single person with no dependants - married couples have different standard rate band cutoffs (up to €88,000 jointly assessed)
- Tax credits include only the personal credit (€2,000) and PAYE credit (€2,000) - additional credits (rent, home carer, medical expenses, etc.) are not modelled
- PRSI assumes Class A employee (most common for PAYE workers) - other PRSI classes have different rates
- Does not model the USC exemption for individuals earning €13,000 or less
- Does not model the PRSI credit for low earners (weekly income €352-€424)
- Does not model: pension contributions (reduce taxable income), BIK (benefit in kind), or Revenue job-seeker credits
- Ireland has no regional or local income taxes - the same rates apply nationwide
