Thinking about how marriage or a civil partnership affects your tax? You’re not alone — and the most common surprise is that nothing happens automatically. For the whole of the year you marry, you’re both still taxed as two single people, and any refund only arrives once someone claims it. This guide explains the three ways a couple can be assessed, what the 2026 figures actually mean, and how to make sure you’re not leaving four years of refunds behind.

Key Takeaways
- Nothing changes in the year you marry — you’re both taxed as single people, and any refund is calculated after 31 December and apportioned from your wedding date.
- The three options are joint assessment, separate assessment and separate treatment. Joint assessment suits most couples; separate treatment is the one that usually costs money.
- In 2026 the standard rate band is €53,000 for a one-income couple, and up to €88,000 where both work — but that €88,000 is not a shared pot, and many couples can’t use all of it.
- The Employee (PAYE) tax credit is never transferable between spouses.
- You can claim back four years. A review in 2026 covers 2022 to 2025.
What Changes When You Get Married?
Less than most people expect, and not straight away.
For the whole of the year in which you marry or register a civil partnership, you and your spouse continue to be taxed as two single people. Nothing changes on your payslip, and Revenue doesn’t recalculate anything on the day.
What happens instead is that after 31 December, your tax for that year can be reviewed. If the two of you together paid more as single people than you would have paid as a married couple, the difference comes back as a refund — apportioned from the date of your marriage to the end of the year. This is often called year of marriage relief, and it’s the single most commonly missed refund we see.
From the following year onward, you choose how you want to be assessed. If you don’t choose, you’ll be treated as jointly assessed by default.
The Three Ways A Couple Can Be Assessed
| Option | What transfers between you | Usually suits |
|---|---|---|
| Joint assessment | Credits and standard rate band, within limits | Most couples, especially uneven incomes |
| Separate assessment | Certain credits, plus anything unused, after year end | Couples who want their affairs kept apart |
| Separate treatment | Nothing | Rarely the best option financially |
Joint Assessment
Joint assessment is the option that benefits most couples in Ireland. You’re treated as one unit, and credits and the standard rate band can be shared between you. If only one of you has taxable income, all the credits and the band can sit with that person.
Where both of you earn, you nominate an assessable spouse — the person responsible for filing and for any tax due. If you don’t nominate anyone, Revenue treats the higher earner as the assessable spouse by default.
Separate Assessment
Under separate assessment your tax affairs stay separate, but you don’t lose the benefit of being a couple. Certain credits are divided between you — the married or civil partner’s credit, the age credit, the blind person’s credit and the incapacitated child credit — and anything one of you doesn’t use can generally go to the other after the year ends.
The Employee (PAYE) tax credit and employment expenses are the exception. They belong to the person who earned them and can never be transferred.
There’s a deadline. Separate assessment must be elected between 1 October of the preceding year and 31 March of the year it applies to. Miss it and you wait a year.
Separate Treatment
The third option is to be taxed exactly as two single people. You each get single-person credits and a single-person band, you each file your own return, and neither of you can claim relief for payments made by the other.
Nothing transfers. For most couples this is the most expensive of the three, and it’s usually chosen for privacy reasons rather than financial ones. It also can’t be backdated — it applies from the point you request it and stays until you change it.
Taxation for Civil Partners in Ireland
Civil partners in Ireland hold the same position as married couples across tax, inheritance, property ownership, pensions and maintenance on separation. Revenue also recognises equivalent legal relationships registered in other countries — marriages, civil unions and partnerships — for tax purposes.
Everything in this guide applies equally to civil partners.
2026 Rates for Married Couples
| 2026 | |
|---|---|
| Standard rate band — single person | €44,000 |
| Standard rate band — couple, one income | €53,000 |
| Standard rate band — couple, two incomes | €53,000 plus the lower of €35,000 or the lower earner’s income (max €88,000) |
| Personal Tax Credit | €4,000 for a married couple or civil partners |
| Employee (PAYE) Tax Credit | €2,000 each — never transferable |
| Home Carer Tax Credit | €1,950 |
If one of you is caring for a dependent person at home, you can claim the Home Carer Tax Credit or the increased standard rate band, but not both. Which one wins depends on the numbers, and it can change from year to year as incomes move.

The €88,000 figure gets quoted everywhere, and on its own it’s misleading. It is not a pot of band a couple can spread across their combined income.
One spouse can hold up to €53,000 of band. The second spouse’s increase — up to €35,000 — is capped at their own income and cannot be transferred to the other. Two worked examples show what that means in practice.
Example 1: incomes of €50,000 and €40,000
The higher earner has a band of €53,000, so their full €50,000 is taxed at 20%. The lower earner’s band is increased by €35,000, so €35,000 of their income is taxed at 20% and the remaining €5,000 at 40%.
- €85,000 at 20% = €17,000
- €5,000 at 40% = €2,000
- Total: €19,000 before tax credits
Treating €88,000 as one shared band would give €18,000 — €1,000 less than the real figure. That’s the mistake most online guides make.
Example 2: incomes of €70,000 and €10,000
The higher earner is capped at €53,000, so €17,000 of their income is taxed at 40%. The lower earner only uses €10,000 of their available €35,000 increase, and the unused €25,000 is lost — it can’t move across.
This couple’s usable band is €63,000, nowhere near €88,000.
Four Things Couples Get Told That Aren’t Right
“We’re married now, so we can earn €88,000 before paying 40%.”
Only if both incomes are high enough to use the band, as the examples above show. For a lot of couples the usable figure is well below €88,000.
“We married in March, so we should have got a refund that year.”
No refund arises during the year of the marriage. It’s calculated after 31 December and apportioned from the date you married — so a March wedding gives roughly ten months’ worth, not twelve.
“Getting married means we’ll pay more tax.”
It never increases your total tax. The worst outcome is that nothing changes, which is common where both spouses earn similar amounts and both are under €44,000.
“Just move my husband’s credits over to me.”
The PAYE credit never moves — each of you keeps your own €2,000 or loses it. Other unused credits and band can shift, but only within the limits above, and generally only after the year has ended.
What We Do, And What We Need From You
This is tedious to work out yourself and easy to get wrong. When you come to us, we:
- Check whether year of marriage relief is due, going back through every open year
- Work out which assessment basis actually leaves you better off, rather than assuming joint is right
- Compare the Home Carer Credit against the increased band and claim whichever is worth more
- Review the last four years for every other credit you’ve missed — medical expenses, flat rate expenses, rent, tuition fees
- Deal with Revenue on your behalf as your registered tax agent (TAIN 66436K)
To get started we need your date of marriage or civil partnership, your spouse’s name and PPS number, and a rough idea of what each of you earns. If one of you is at home caring for children or a relative, tell us — it changes which option is best.
Both of you need to sign. One spouse can’t authorise us to act for the other, so if your husband or wife isn’t already a client, they’ll need to complete their own short authorisation. It takes a couple of minutes and we’ll send it on.
You can go back four years. A review done in 2026 covers 2022, 2023, 2024 and 2025 — so if you married in 2022 and never had the year of marriage review done, this is the last year it’s reachable.
When The Rules Are Different
Everything above assumes two PAYE employees living in Ireland. Talk to us directly rather than relying on this page if any of the following apply, because the position changes:
- Either of you is self-employed, self-assessed, or a company director
- Either of you lives or works abroad, or isn’t Irish-resident for tax
- You’re separating or divorcing, or a spouse has died — different reliefs apply and this page doesn’t cover them
- You have rental income, investment income, or income outside the PAYE system

Marriage Tax Credits FAQs
1. Do you pay less tax if you are married?
Often, but not always. Couples with uneven incomes usually gain, because band and credits can be shared. Two people earning similar amounts, both under €44,000, typically see no difference at all. Marriage doesn’t increase anyone’s tax — the worst case is that it changes nothing.
2. When do I get my marriage tax refund?
Not in the year you marry. For that year you’re both still taxed as single people, and any refund is only calculated after 31 December. It’s also apportioned — based on the part of the year you were married, not the whole year.
3. Can a married couple in Ireland earn €88,000 before paying 40% tax?
Only if both incomes are high enough to use the band. One spouse can hold up to €53,000, and the second spouse’s increase of up to €35,000 is limited to their own income and cannot be transferred. A couple earning €70,000 and €10,000 has a usable band of €63,000, not €88,000.
4. Does my spouse need to apply separately?
They need to sign their own authorisation, yes. One spouse cannot authorise a tax agent to act on the other’s behalf. It’s a short form and we’ll send it to them directly — you don’t need to chase it yourself.
5. Which assessment option is best?
Joint assessment suits most couples, particularly where one partner earns much more or isn’t working. Separate assessment usually produces the same total, just split differently. Separate treatment is the one that tends to cost money, because nothing transfers between you. Which is right for you depends on both incomes, so it’s worth having it checked rather than guessing.
6. Can I claim the Home Carer Tax Credit and the increased standard rate band?
No — it’s one or the other. Which is worth more depends on both incomes, and the answer can change from year to year, so it’s worth checking each year rather than setting it once.
7. Do civil partners get the same treatment as married couples?
Yes. Registered civil partners have the same position for tax, inheritance, property, pensions and maintenance. Revenue also recognises equivalent legal relationships registered in other countries.
8. We’ve been married for years and never looked at this. Is it too late?
Not entirely. You can claim back four years, so a review in 2026 covers 2022 to 2025. Anything before that is out of reach, but four years of unclaimed credits is often worth more than people expect.
9. What if we’re separating?
Different rules apply, and none of the above is a safe guide. Separation, divorce and bereavement each have their own treatment and reliefs. Get in touch and we’ll look at it properly rather than working from general guidance.
