Navigating Income Tax for Married Persons and Civil Partners in Ireland

Understanding the nuances of income tax can be challenging, especially for married persons and civil partners. This guide, based on the Irish Tax and Duty Manual, clarifies the essential aspects of income tax treatment for these groups under the Taxes Consolidation Act 1997 (TCA).


This manual provides a comprehensive overview of the income tax treatment applicable to married persons and civil partners, referencing Parts 44 and 44A of the TCA. It covers various scenarios, including the year of death of a spouse or civil partner, the year of separation, divorce or dissolution, and maintenance payments.

Recognition of Same-Sex Marriage and Civil Partnerships

Civil Partnerships: Recognized in Ireland from 2011, civil partnerships were provided for under the Civil Partnership and Certain Rights and Obligations of Cohabitants Act 2010. The tax treatment for these partnerships is outlined in Part 44A TCA.

Marriage Act 2015: From November 16, 2015, same-sex marriages are recognized in Ireland, and no new civil partnerships can be registered. Couples who were in civil partnerships before this date continue to be recognized under the same status for tax purposes.

Year of Marriage or Registration Relief

In the year of marriage or registration, couples are taxed as single individuals. However, relief may be available if joint assessment results in a lower tax liability. This relief is calculated based on the number of months the couple has been married or in a civil partnership within the tax year.


A couple married on July 10, 2024. Their combined tax as single individuals is €8,100. Under joint assessment, their tax liability is €6,900. They are entitled to a repayment calculated proportionally to the months they were married within the year.

Subsequent Years - Basis of Assessment

Couples can choose between three assessment options:

1. Joint Assessment: The most beneficial for most couples, allowing the sharing of tax credits and rate bands. The assessable spouse or nominated civil partner is responsible for tax returns and payments.

2. Separate Assessment: Each spouse or civil partner is assessed on their own income, but unused credits and reliefs can be transferred.

3. Separate Treatment: Everyone is taxed separately with no transfer of credits or rate bands, which can result in higher tax liability if one partner cannot fully utilize their credits and reliefs.


Non-Residence and Aggregation of Income

One Spouse Resident: If only one spouse is resident in Ireland, they are taxed as a single person unless they elect for joint assessment, considering the non-resident spouse has no income.

Both Non-Resident: If both spouses are non-resident but one earns income in Ireland, they can claim personal tax credits proportionate to their Irish income, provided 75% or more of their worldwide income is taxable in Ireland.

Widowed Persons or Surviving Civil Partners

In the year of a spouse or civil partner's death, the survivor retains the higher personal tax credit for that year. In subsequent years, they receive a higher personal tax credit for up to five years, with specific amounts decreasing annually.

Separation, Divorce, or Dissolution

The tax treatment in the year of separation, divorce, or dissolution depends on the assessment method used before the event. Special rules apply to legally enforceable maintenance payments, with relief available for payments made to the other spouse or civil partner.

Maintenance Payments

Legally enforceable maintenance payments are deductible for the payer and taxable for the recipient. Voluntary maintenance arrangements do not qualify for tax deductions, but the payer may be entitled to a personal tax credit.

Foreign Divorce or Dissolution

Maintenance payments under a foreign divorce are eligible for tax relief if the divorce is recognized in Ireland.
