Taxation of married people and civil partners
If you get married, both you and your spouse continue to be treated as single people for tax purposes in that year. If, however, the tax you pay as two single people is greater than the tax that would be payable if you were taxed as a married couple, you can claim the difference a tax refund. Refunds are only due from the date of marriage and will be calculated after the following 31 December. So, for example, if you get married in 2021, any tax refund due to you will be calculated after 31 December 2021.
Refunds are normally only due where a couple are taxed at different rates and one spouse could benefit from the unused standard rate cut-off point or for some of the unused tax credits of the other spouse.
When you get married it is important to advise the tax office of the date of your marriage. You will also need to quote your own and your spouse's Personal Public Service Number (PPS number).
Taxation of civil partners
Civil partners are entitled to the same rights as married couples in financial matters such as tax, inheritance, property, pensions and maintenance if the relationship breaks down. Your civil partnership does not have to be registered in Ireland. Some legal relationships between same sex couples that are recognised by a foreign state (such as marriage, civil union, civil partnership) are recognised by the Minister for Justice and Equality. Any partnerships on the Minister’s list are recognised by Revenue for taxation purposes.
Since the commencement of the Marriage Act 2015 on 16 November 2015, no new civil partnerships can be registered unless the couple notified the registrar of their intention to enter a civil partnership before that date. More information is available in our document about Civil partnership and same-sex couples.
For the years following your marriage or civil partnership, there are three options for taxation:
- Assessment as a single person (you are both still taxed as single people)
- Separate assessment
- Joint assessment or aggregation
Assessment as a single person
Under assessment as a single person, each spouse/civil partner is treated as a single person for tax reasons. With this option:
- Both spouses or civil partners are taxed on their own income
- Both spouses or civil partners get tax credits and the same standard rate cut-off point due to a single person
- Both spouses or civil partners pay their own tax
- Both spouses or civil partners complete their own return of income form and claim their own tax credits. One spouse or civil partner cannot claim relief for payments made by the other. There is no right to transfer tax credits or standard rate cut-off point to each other.
To claim assessment as a single person, you will have to contact your tax office. Either spouse or civil partner can make the claim and the option remains until the person who claims it changes their mind. If you want to claim assessment as a single person, you must apply within the tax year (preferably at the start of the year).
Choosing to be assessed as a single person when you are married or in a civil partnership is unfavourable in some circumstances. This is mainly because you cannot transfer any unused tax credits or standard rate cut-off point. You cannot claim Home Carer's Tax Credit if your spouse or civil partner is caring for a dependent person and would otherwise qualify for the relief.
Under the separate assessment option, the tax affairs of spouses or civil partners are independent of each other. The difference between separate assessment and assessment as a single person is that some tax credits are divided equally between you under the separate assessment option. These tax credits are:
- Married or Civil Partner's Tax Credit
- Age Tax Credit
- Blind Person's Tax Credit
- Incapacitated Child Tax Credit.
The balance of the tax credits is given to each of you in proportion to the cost borne by you. The Employee Tax Credit (formerly known as the PAYE tax credit) and expenses (if any), are allocated to the appropriate spouse/civil partner. Any tax credits other than the Employee Tax Credit and employment expenses that are unused by one partner can be claimed by the other spouse/civil partner. The tax credits are not usually adjusted until after the end of the tax year.
Any tax credits that are unused (other than the Employee Tax Credit and employment expenses) and the standard rate cut-off point up to €44,300 in 2021 can be transferred to the other spouse/civil partner but only at the end of the tax year. The increase in the standard rate tax band of up to €26,300 in 2021 is not transferable between partners. If you think you have unused tax credits or standard rate cut-off point, contact your tax office for a review after the end of the tax year. Overall, the amount of the tax that is payable under this option (separate assessment) is the same that is payable under the joint assessment option discussed below.
The claim for separate assessment must be made between 1 October of the preceding year and the 31 March in the year of the claim. Either spouse or civil partner can request this form of assessment, although the other spouse or civil partner will have to confirm this request. Separate assessment will then continue until you request to change it. These requests can be managed in your myAccount or in writing to Revenue. Each spouse or civil partner can complete a separate return of their own income.
The joint assessment (or "aggregation") option is usually the most favourable basis of assessment for a married couple or civil partners. This option is automatically given by the tax office when you advise them of your marriage or civil partnership, but this does not prevent you from choosing any of the options examined earlier. Under this option, the tax credits and standard rate cut-off point can be allocated between spouses to suit their own circumstances.
If only one spouse or civil partner has taxable income, all tax credits and the standard rate cut-off point will be given to the spouse or civil partner with the income.
If both of you have taxable income, you can decide which of you is to be the assessable spouse or nominated civil partner. You then ask the tax office to allocate the tax credits and standard rate cut-off point between you in whatever way you want. (The Employee Tax Credit, employment expenses and the increase in standard rate cut-off point of €26,300 in 2021 are not transferable).
If your tax office does not get a request from you to allocate your tax credits in any particular way, the tax office will normally give all the tax credits (other than the other partner's Employee and expense tax credits) to the spouse or civil partner being assessed. The spouse or civil partner being assessed must complete the return of income for the couple and is charged for tax on the joint income of the couple.
If one spouse or civil partner is self-employed, joint assessment can still apply. The flexibility this option brings can be very convenient - especially if one of you pays tax under the PAYE system and the other pays tax under the self-assessment system. Under joint assessment, you let your circumstances determine if most of the tax should be paid under PAYE or in a lump sum on assessment. This is determined by the way in which the tax credits are allocated. If you choose to pay most of your tax under PAYE, the tax credits (apart from the Employee Tax Credit and employment expenses), should be offset against the self-assessment income.
The choice about who becomes the assessable spouse or nominated civil partner is made by both of you. All you need to do is to inform Revenue which of you is to be the assessable spouse or nominated civil partner. If you have not made your nomination, the spouse or civil partner with the higher income in the latest year for which details of both spouses' incomes are known becomes the assessable spouse or nominated civil partner. This person continues to be the assessable spouse or nominated civil partner until both of you jointly elect that the other spouse or civil partner is to be the assessable spouse or nominated civil partner or until either of you opts for either separate assessment or assessment as a single person.
Repayments of tax
Repayments that arise from an end of year review will in general be apportioned and repaid on the basis of the tax paid by each spouse/civil partner.
If both of you are in employment, then a Tax Credit Certificate is issued to each of you. All of the tax credits and reliefs due to a married couple or civil partners where joint assessment applies are shown on the assessable spouse/nominated civil partner's notice - the amount "allocated to other employments" is also shown. This amount ("allocated to other employments") represents the tax credits that are allocated to the other spouse/civil partner and may also include tax credits that are allocated to a subsidiary employment or pension of either spouse or civil partner.
The standard rate cut-off point for married couples/civil partners is €44,300 in 2021. This amount is taxed at 20% and the balance is taxed at 40%. Where both spouses/civil partners have income, this standard rate cut-off point can be increased by the lower of the following:
- €26,300 in 2021 or
- The amount of the income of the spouse/civil partner with the smaller income.
The increase in the standard rate cut-off point interacts with the Home Carer's Tax Credit. If the increased standard rate cut-off point is more beneficial than the Home Carer's Tax Credit, you can claim the increase instead. As a matter of course, the tax office will grant you whichever is more beneficial to you. More information is available on revenue.ie about the Home Carer's Tax Credit.
