A Complete Guide to Income Tax in Ireland for Foreigners and Non-Residents

Core Concepts at a Glance

Do Foreigners Pay Income Tax in Ireland?

Yes — income tax in Ireland for foreigners applies if you earn income in the country, even if you’re not a resident. Whether you’re employed, self-employed, or receive rental or investment income, you’ll need to assess your tax status as an expat in Ireland and fulfill your filing requirements accordingly.

Tax Residency Rules in Ireland

Your tax residency in Ireland determines whether you’re taxed on Irish-sourced income only or worldwide income. According to Irish tax residency rules, you’re generally considered a resident if:

• You spend 183 days or more in Ireland in a calendar year, or
• You spend 280 days over two consecutive years, with at least 30 days in each.

Even if you’re not technically a resident, your non-resident tax obligations in Ireland may still apply on Irish income. This is where options like split-year treatment in Ireland come into play — a mechanism that allows certain income earned before arrival or after departure to be exempt from full-year taxation.

How to Get a PPS Number in Ireland

The Personal Public Service (PPS) number is your unique tax identification number in Ireland and is essential for accessing public services, employment, and taxation. If you’re earning income as a non-resident or expat, you’ll need a PPS number to properly register for tax and be included in the PAYE system.

To obtain a PPS number for tax in Ireland, follow these steps:

• Provide valid identification (passport or national ID)
• Show evidence of your purpose in Ireland (e.g., job offer or university letter)
• Submit proof of address (lease agreement or utility bill)

Once your application is approved, your PPS number for foreign workers is issued and becomes your key identifier for tax and public services, linking you to employment rights, PRSI and USC, and Irish tax return services.

PAYE in Ireland for Expats

Foreign employees working for Irish companies are typically taxed through the PAYE system in Ireland (Pay As You Earn). Employers deduct income tax, PRSI, and USC directly from your wages.

• PRSI and USC for foreigners apply similarly to residents.
• If you’re employed short-term, special reliefs may apply.
• Ensure your tax credits are adjusted for your non-resident status.

If you’re not eligible for full credits, you may still be able to claim non-resident tax credits in Ireland under certain circumstances.

Income Tax Rates and Non-Resident Obligations

Ireland uses a progressive tax system for individuals, including expats:

• 20% on income up to a threshold (varies by personal circumstances)
• 40% on income above that threshold

In addition to income tax, you’ll also pay PRSI and USC if applicable. However, non-residents may be exempt from some social charges, depending on their country of residence and applicable double tax treaties Ireland has in place.

Double Taxation and Treaties

Ireland has tax treaties with more than 70 countries. These double tax treaties help prevent you from being taxed twice on the same income — once in Ireland and again in your home country.

• Use tax treaty benefits to claim a foreign income tax credit in Ireland.
• File for double taxation relief in Ireland via your Irish tax return for non-residents.

Understanding the remittance basis in Ireland is also crucial. If you’re non-domiciled and not ordinarily resident, you may be taxed only on foreign income that is remitted (brought) into Ireland.

Special Reliefs for International Employees

Ireland offers several programs to attract high-value international talent:

Special Assignee Relief Programme (SARP)

The SARP tax relief in Ireland provides income tax relief for qualifying employees assigned to work in Ireland by a foreign employer. Key features include:

• Applies to earnings over €100,000
• Relief of up to 30% on qualifying income
• Must apply within 90 days of arrival
• Must remain a tax resident for each year claimed

Key Employee Engagement Programme (KEEP)

The KEEP scheme in Ireland offers favorable capital gains tax treatment for employee share options in startups and SMEs. It’s designed to retain key talent in competitive industries.

Filing a Tax Return as a Non-Resident

If you earn Irish-sourced income, you’re required to file an Irish tax return for non-residents, even if you’re exempt from full tax under a treaty or split-year treatment. This return is filed through the Revenue Online Service (ROS).

You may need to:

• Report all Irish income
• Claim non-resident tax credits Ireland
• Apply any double taxation Ireland relief
• Include any foreign income if required
