Who Pays Income Tax in Ireland?
You generally pay Irish income tax if you are:
- Resident and domiciled in Ireland – usually taxed on your worldwide income
- Resident but not domiciled – generally taxed on Irish‑source income and certain foreign income
- Non‑resident – normally taxed only on Irish‑source income (for example, Irish rental income or employment duties carried out in Ireland)
Employees normally pay tax through the PAYE system. Self‑employed people, landlords and company directors usually fall under self‑assessment and must file a tax return each year.
How Irish Income Tax Rates and Bands Work
Income tax in Ireland uses a progressive system with two main rates:
- Standard rate: 20%
- Higher rate: 40%
For 2025, the standard rate band is:
- Single person: first €44,000 @ 20%
- One‑parent family: first €48,000 @ 20%
- Married couple / civil partners (one or two incomes): first €53,000 @ 20%
Any taxable income above your standard rate band is taxed at 40%.
Your total taxable income is made up of:
- Employment income (wages, bonuses, benefits in kind)
- Self‑employed trading or professional income
- Rental profits
- Most pensions and some social welfare payments
- Certain investment income and benefits
Some income can be exempt or taxed under special rules (for example, Rent a Room Relief, qualifying pension contributions, certain statutory redundancy payments).
Main Irish Income Tax Credits (2025)
Tax credits reduce the tax you pay, not your income. After calculating your gross income tax at 20% and 40%, you subtract your tax credits to arrive at your final income tax bill.
Key personal tax credits for 2025 include:
-
Personal Tax Credit
- €2,000 – single / widowed / surviving civil partner
- €4,000 – married couple / civil partners (jointly assessed)
-
Employee (PAYE) Tax Credit – €2,000
- For those taxed through PAYE on employment or pension income
-
Earned Income Tax Credit – €2,000
- For self‑employed individuals and proprietary directors
- Cannot be combined with PAYE credit for the same income, but you can claim the higher of the two where both might apply
-
Single Person Child Carer Credit – €1,900
- For a qualifying single parent or person with day‑to‑day care of a qualifying child
-
Blind Person Tax Credit – €1,950
- Higher amounts can apply if both spouses or civil partners are blind
- Incapacitated Child Tax Credit – €3,800 per qualifying child
There are many other specific credits and reliefs (for example, home carer credit, age credit, certain medical reliefs, pension contribution relief) that may apply depending on your circumstances.
USC and PRSI
In addition to income tax, most individuals also pay:
Universal Social Charge (USC)
USC is charged on gross income above certain thresholds, at different rates and bands depending on income level, age and medical card status. Some income, such as certain social welfare payments, is exempt from USC.
PRSI (Pay Related Social Insurance)
PRSI is a social insurance contribution that helps fund entitlements such as:
- State Pension (Contributory)
- Illness, maternity and jobseeker benefits
Employees normally pay PRSI Class A through PAYE; self‑employed individuals generally pay PRSI Class S through self‑assessment.
How Income Tax Is Calculated in Practice
In simplified terms, your annual income tax calculation usually follows these steps:
1. Add all taxable income for the year (employment, self‑employed, rental, etc.).
2. Deduct allowable expenses and reliefs, such as pension contributions, qualifying trading expenses, rental expenses and other specific deductions.
3. Apply the 20% rate up to your standard rate band and 40% on income above that.
4. Subtract your tax credits (personal, PAYE or earned income, single person child carer, etc.).
5. Add USC and PRSI to find your total tax liability.
6. Deduct any tax already paid at source (PAYE, RCT, preliminary tax) to see if you owe tax or are due a refund.
Filing and Paying Irish Income Tax
How you declare and pay income tax depends on your situation:
-
Employees (PAYE only, no additional significant income)
- Tax is deducted by your employer under PAYE
- You can review and correct your tax online for each year (for example, to claim additional credits or expenses)
-
Self‑employed, landlords, company directors, or those with significant additional income (usually over €5,000)
- Must register for self‑assessment
- File a Form 11 tax return by the annual deadline
- Pay preliminary tax for the current year and any balance of tax for the previous year
-
PAYE taxpayers with small amounts of non‑PAYE income
- May need to complete a Form 12 return, often online
Keeping good records of all income, expenses, and supporting documents is essential in case Revenue reviews your affairs.
