Key takeaway
Your tax obligations when you move back to Ireland — becoming tax resident, split-year treatment, foreign income, and how to register with Revenue.
Becoming tax resident in Ireland again
You are considered tax resident in Ireland if you spend 183 days or more in the country during a tax year, or 280 days or more across two consecutive tax years. Once you become tax resident, your worldwide income is generally taxable in Ireland (subject to double taxation treaties with other countries).
Split-year treatment
In the year you return to Ireland, you may be able to avail of "split-year treatment" — where you're only taxed on Irish income for the part of the year you were resident in Ireland, rather than your full worldwide income for the year. This is not automatic; you must apply to Revenue for it. Get advice from an accountant or tax adviser if you're returning with significant income.
Foreign income and pensions
Income you earned abroad before returning to Ireland is generally not taxable in Ireland. However, once you're resident in Ireland, income from foreign investments, rental properties abroad, or foreign pensions may become taxable here (again, subject to double taxation treaties). Revenue's guidance for returning emigrants is available on revenue.ie.
Registering with Revenue
- Create a myAccount at revenue.ie
- Register your new job or self-employment
- Ensure your employer has your Tax Credit Certificate so you're not put on emergency tax
- Claim any applicable tax credits (rent credit, medical expenses, etc.)
Capital gains from abroad
If you sell property or investments while resident in Ireland, Capital Gains Tax (CGT) at 33% applies to any gains. Property or assets sold before you became Irish resident again are generally not subject to Irish CGT — but get professional advice if you have significant assets as the rules are complex.
Getting advice
If your financial situation is complex (pension from abroad, property in multiple countries, significant savings), it's worth consulting a tax adviser who specialises in returning emigrants. The Irish Tax Institute maintains a register of qualified tax practitioners.
