Irish tax feels easy for employees and surprisingly sharp-edged for everyone else. If you take a salaried job, most of it happens in the background, provided you register in the right order. If you have foreign income, a freelance side activity or a house somewhere else, the same system asks you to make decisions in a calendar year you cannot easily redo. This is an overview of taxes in Ireland for people who have just arrived, based on the 2026 figures on Revenue's and Citizens Information's pages.
Are you tax resident in Ireland?
The tax year is the calendar year. You are a tax resident if you spend 183 days or more in Ireland in that year, or 280 days or more across the current and previous year together. A day counts if you are in Ireland at any time on that day, except in an airport transit zone or when an unexpected event, like a storm, stops you from leaving.
The second test is the one that surprises people: you can be resident in a year in which you spent fewer than 183 days in Ireland, because the days of the previous year count too (a year with 30 days or fewer is left out of this test).
Residents are generally taxed on worldwide income. If you are resident but not domiciled in Ireland (domicile is roughly your permanent home country), you may be taxed on foreign income only to the extent you bring it into Ireland. That is the remittance basis, and it is more nuanced than it sounds: savings built before you became resident can come in tax-free, while savings from income earned during your residence may be taxed on transfer.
What is the split-year treatment?
In the year you arrive, you can ask for split-year treatment if you were not resident the previous year and will be resident the following year. Employment income you earned abroad before you arrived is ignored for Irish tax, and you generally receive the full year's tax credits. It applies to employment income only; foreign rent or investments follow the general rules. You request it through MyEnquiries in myAccount or by post, or, if you arrived after 31 December 2024, through your income tax return.
You can also choose to be resident from your arrival year, if you intend to stay in the next, by telling Revenue in writing.
What are the income tax rates in Ireland in 2026?
Income tax has two rates, 20% and 40%, and your standard-rate band depends on your family situation:
- Single person: 20% up to €44,000.
- Single parent (Single Person Child Carer credit): €48,000.
- Married or civil partners, one income: €53,000.
- Married or civil partners, two incomes: €53,000 plus up to €35,000, capped at the lower earner's income and not transferable.
Then come the credits. In 2026, the personal credit is €2,000 (€4,000 for a couple), the employee credit €2,000, and the earned income credit up to €2,000 for self-employed income. A single employee therefore gets €4,000 of credits against the tax calculated.
The tax is calculated on your income with these rates, then reduced by your credits; USC and PRSI come on top. Your Revenue Payroll Notification and your payslips show how this applies to you.
What are USC and PRSI?
The Universal Social Charge (USC) applies on top of income tax. In 2026, nothing is due if your annual income is €13,000 or less; otherwise rates run from 0.5% to 8%, split in bands (0.5% up to €12,012, 2% up to €28,700, 3% up to €70,044 and 8% above). Even with no income tax after your credits, you may owe USC.
PRSI is the social insurance contribution. For an employee in class A it was 4.2% until 30 September 2026 and 4.35% from 1 October 2026, applied to all pay once earnings pass €352 a week. This contribution builds your State pension and short-term benefit entitlements.
Which bracket you fall in, whether split-year treatment helps you, and what happens to foreign income all depend on dates and domicile. If you are not sure where your case sits, Moovy can explain the rules and point you to the Revenue page that settles it, though a tax adviser should check a complex file.
How do you avoid emergency tax?
Emergency tax is a punitive-looking rate that your employer must apply when Revenue gives them no credit and band information. It usually happens to newcomers who start work before their details are registered. You get the money back, but later and after a cash-flow dent.
The remedy takes a few minutes if you have a PPS number (see the PPS number guide):
- Create your myAccount on revenue.ie.
- Under PAYE Services, choose "Add Job or Pension Details" and enter your employer's tax registration number, your start date, how often you are paid and your residence status.
- Revenue sends your employer a Revenue Payroll Notification with your credits and bands.
Only the first job needs this step. For later jobs, your employer registers you.
Then claim any credits that apply. The Rent Tax Credit is worth up to €1,000 a year for a single person, €2,000 for a couple taxed together, in 2026. You claim it in myAccount; see renting in Ireland.
If you have foreign income, a home abroad or a partner who stays in another country, have your first Irish year checked by a tax adviser in Ireland before you file.
Who has to file a return?
If you are self-employed or have other income, the self-assessment calendar applies. The Form 11 for 2025 income is due by 31 October 2026, or 18 November 2026 if you file and pay through ROS (the Revenue Online Service); the extension applies only if you do both online. Late filing costs a surcharge of 5% of tax due (capped at €12,695) within two months, and 10% (capped at €63,485) after that, plus daily interest. For a business, see start a business in Ireland.
Employees with modest side income (rent, investments, foreign income) can use a Form 12 in myAccount up to €5,000 of taxable income, and €30,000 gross.
What changes in 2027?
Budget 2027 was announced on 6 October 2026, and the related bill was introduced in the Dáil on 19 October 2026 but not voted at the time of writing. If passed, the 20% band for a single person rises to €46,500 and the main credits to €2,125 from January 2027; the rates stay at 20% and 40%. Do not use these figures for your 2026 income.
How do taxes in Ireland work for employees and the self-employed?
Employees are taxed through PAYE, the pay-as-you-earn system: your employer deducts income tax, USC and PRSI each pay period using the credits and bands Revenue sends them. The self-employed use self-assessment: you register as a sole trader, keep records, and file a Form 11 with your preliminary tax each year. The rates are the same, but the timing differs, and so do contributions: class S PRSI applies to self-employed income, at 4.35% from 1 October 2026 (or €650 if higher).

Which other taxes in Ireland should newcomers know?
- VAT is added to goods and services, at 23% for the standard rate, with reduced rates of 13.5% and 9%.
- Local Property Tax is due by the owner of a home, not the tenant, unless the lease lasts 20 years or more.
- Stamp duty applies when you buy a home: 1% on the first €1 million.
- Vehicle Registration Tax and motor tax apply to a car; see driving in Ireland.
What do you do if you leave Ireland later?
Leaving does not end your Irish tax story at once. After three consecutive years of residence, you become ordinarily resident from the fourth year and stay so for three years after you leave. During those years you generally remain taxable in Ireland on your worldwide income, with exceptions such as work carried out entirely abroad or other foreign income of €3,810 or less. For a former resident, keep your records of the days you spent in the country and ask Revenue for a Letter of Residence if a foreign tax office asks you to prove your status.
Does the Special Assignee Relief Programme apply to you?
SARP is for senior employees posted by their employer. For arrivals from 1 January 2026, 30% of salary above €125,000, up to €1,000,000, is exempt from income tax (not USC), for up to five consecutive years. The employer must certify within 90 days of your arrival, you need at least six months' prior employment with them outside Ireland, you must not have been resident in Ireland in the previous five years, and your base salary must be at least €125,000 a year. If you are in that position, ask your employer for the certification before you arrive. Most newcomers are not eligible.
What are the traps?
- Thinking 183 days is a safe harbour. The 280-day test can make you resident.
- Forgetting foreign income. Residents declare it.
- Assuming the split-year covers rental or investment income. It does not.
- Staying "ordinarily resident" without noticing. After three consecutive years, you remain ordinarily resident for three years after leaving, with some foreign income still taxable in Ireland.
- Using a general article as personal advice. Treaty rules between Ireland and your home country differ.
