Quick Summary
- Marriage Allowance lets you transfer £1,260 of Personal Allowance to your spouse or civil partner, saving the recipient up to £252 per year in income tax
- Scotland's narrower Basic rate band (£12,571–£27,491) means fewer couples qualify than in England, where the Basic rate stretches to £50,270
- You can backdate your claim up to four years, meaning a first-time claim in 2026/27 could be worth over £1,000 in total
- Check your eligibility — use the Scottish Income Tax Calculator to see which tax band you fall into
Marriage Allowance is one of the most under-claimed tax reliefs in the UK. HMRC estimates that over two million eligible couples still haven't applied. If you're married or in a civil partnership and one of you earns under £12,570, you could be missing out on £252 a year — for doing nothing more than filling in a short online form.
Quick Answer: Marriage Allowance lets a non-taxpayer (earning under £12,570) transfer £1,260 of their unused Personal Allowance to their spouse or civil partner. The recipient saves 20% of £1,260, which is £252 per year. In Scotland, the recipient must be in the Basic rate band (earning between £12,571 and £27,491). If they earn above £27,491, they move into the Intermediate band and no longer qualify — a key difference from England.
What is Marriage Allowance?
Marriage Allowance (officially called the Transferable Tax Allowance) was introduced in April 2015. It allows one spouse or civil partner to transfer 10% of their Personal Allowance — £1,260 in 2026/27 — to the other.
The transferor (the person giving up allowance) must earn below the Personal Allowance threshold of £12,570. They don't use all of their tax-free allowance, so they shift £1,260 of it to their partner. The recipient then gets a larger tax-free amount (£13,830 instead of £12,570), reducing their tax bill by £252.
This is not the same as the older Married Couple's Allowance, which applies only to couples where one partner was born before 6 April 1935. Marriage Allowance is for everyone else who meets the criteria.
How the £252 saving is calculated
The maths is straightforward:
- Transferred allowance: £1,260
- Tax rate applied: 20% (Basic rate)
- Annual saving: £1,260 x 20% = £252
The saving is always calculated at 20% — the UK Basic rate — regardless of whether you live in Scotland or England. This is because Marriage Allowance is a UK-wide relief administered by HMRC, and the reduction is applied as a tax credit at the Basic rate.
Who qualifies for Marriage Allowance in Scotland?
Both partners must meet specific conditions. Get any one of these wrong and the claim will be rejected.
The transferor (lower earner) must:
- Be married or in a civil partnership (living together as an unmarried couple does not count)
- Have income of £12,570 or less in the tax year (this means they have unused Personal Allowance)
- Not be liable to income tax after their Personal Allowance is applied
The recipient (higher earner) must:
- Be a Basic rate taxpayer in Scotland — earning between £12,571 and £27,491
- Not be in the Intermediate, Higher, Advanced, or Top rate band
Scotland's Basic rate band runs from £12,571 to £27,491. In England, the Basic rate band stretches all the way to £50,270. This means a Scottish couple where the higher earner makes £30,000 would NOT qualify, even though the same couple living in England would. This is the single biggest Scotland-specific trap with Marriage Allowance.
Scotland vs England: the eligibility gap
| Scotland | England | |
|---|---|---|
| Basic rate band | £12,571–£27,491 | £12,571–£50,270 |
| Basic rate | 20% | 20% |
| Maximum saving | £252 | £252 |
| Recipient income ceiling | £27,491 | £50,270 |
The saving amount is identical — £252 per year — but the pool of eligible recipients is much smaller in Scotland. Any Scottish taxpayer earning above £27,491 moves into the Intermediate band (21%) and loses eligibility.
This matters because a large chunk of working couples have one partner earning between £27,492 and £50,270. In England, those couples qualify. In Scotland, they don't.

Worked example: how Marriage Allowance saves a Scottish couple £252
Meet Claire and David. Claire works part-time and earns £10,000 per year. David earns £25,000 per year. They are married and both live in Scotland.
Without Marriage Allowance:
| Claire | David | |
|---|---|---|
| Gross income | £10,000 | £25,000 |
| Personal Allowance | £12,570 | £12,570 |
| Taxable income | £0 | £12,430 |
| Income tax | £0 | £2,237 |
David's tax breakdown: £2,826 taxed at 19% Starter rate (£12,571–£15,397) = £537, then £9,604 taxed at 20% Basic rate (£15,398–£25,000) = £1,921. Total: £2,458.
With Marriage Allowance:
Claire transfers £1,260 of her Personal Allowance to David. Her Personal Allowance drops to £11,310 — but since she only earns £10,000, this changes nothing for her. David's Personal Allowance rises to £13,830.
| Claire | David | |
|---|---|---|
| Gross income | £10,000 | £25,000 |
| Personal Allowance | £11,310 | £13,830 |
| Taxable income | £0 | £11,170 |
| Tax saving | — | £252 |
David now has £1,260 less taxable income. The £252 saving is applied as a tax reduction (credit) on his tax bill. The couple keeps an extra £252 per year — or £21 per month.
Backdating makes it more valuable
You can backdate a Marriage Allowance claim up to four tax years. If Claire and David had been eligible since 2021/22 and never claimed, they could receive:
| Tax year | Saving |
|---|---|
| 2021/22 | £252 |
| 2022/23 | £252 |
| 2023/24 | £252 |
| 2024/25 | £252 |
| 2026/27 | £252 |
| Total | £1,260 |
HMRC pays the backdated amount as a lump sum, and the current year's allowance is applied through the recipient's tax code.
How to claim Marriage Allowance
Claiming is free and takes about ten minutes. Do not pay a third-party website to do it — several companies charge a fee to submit the same free form.
- Go to gov.uk/marriage-allowance
- Check eligibility using the online tool
- Sign in with Government Gateway (or create an account if you don't have one)
- Enter your details and your partner's details — you'll need both National Insurance numbers
- Submit — HMRC will adjust the recipient's tax code, usually within a few weeks
The transferor (lower earner) is the one who applies. You cannot apply on behalf of your partner.
Once you've applied, Marriage Allowance renews automatically each year. You only need to cancel it if your circumstances change — for example, if the transferor starts earning above £12,570 or the recipient moves into a higher tax band.
When Marriage Allowance is NOT worth it
Marriage Allowance sounds like free money, but there are situations where it doesn't apply or could cause problems.
The recipient earns above £27,491 (Scotland)
This is the most common mistake for Scottish couples. If the higher-earning partner is in the Intermediate band (£27,492–£43,662) or above, they do not qualify. The relief is restricted to Basic rate taxpayers only.
If the recipient's income fluctuates — say they earn £26,000 some years and £29,000 in others — you should only claim for the years where their income falls within the Basic rate band.
The transferor earns above £12,570
If the lower-earning partner earns more than £12,570, they are already using their full Personal Allowance and have none to transfer. Marriage Allowance does not help this couple.
Both partners earn over £12,570
If both of you are taxpayers, neither can transfer allowance. Marriage Allowance only works when one partner has unused Personal Allowance.
The couple is unmarried
Cohabiting couples cannot claim Marriage Allowance, no matter how long they have lived together. You must be legally married or in a registered civil partnership.
Income is from savings or dividends only
If the transferor's income is entirely from savings interest or dividends that fall within the Savings Allowance or Dividend Allowance, they may already pay no tax without needing Marriage Allowance. The claim would still work, but check whether the transferor would inadvertently create a tax liability on their own income by reducing their Personal Allowance.

Common mistakes Scottish couples make
Mistake 1: Assuming England's rules apply
Many online guides describe Marriage Allowance using England's figures. They say the recipient can earn up to £50,270 — which is England's Basic rate ceiling. In Scotland, the ceiling is £27,491. If you rely on English guidance, you might claim when you're not eligible.
Mistake 2: The wrong partner applies
The lower earner (transferor) must be the one who submits the application. If the higher earner tries to apply, the form won't work.
Mistake 3: Not cancelling when circumstances change
If the recipient gets a pay rise that pushes them into the Intermediate band, you should cancel Marriage Allowance. Otherwise, HMRC may claw back the relief at the end of the tax year through a tax code adjustment or Self Assessment bill.
Mistake 4: Paying a claims company
Several companies advertise Marriage Allowance claims and take a cut of your refund — often 30-40%. The process is free on gov.uk and takes minutes. There is no reason to pay someone else to do it.
Marriage Allowance vs Married Couple's Allowance
These are two different reliefs. You cannot claim both.
| Marriage Allowance | Married Couple's Allowance | |
|---|---|---|
| Who qualifies | Married/CP couples (any age) | One partner born before 6 April 1935 |
| How it works | Transfer £1,260 of Personal Allowance | Fixed allowance (£4,280–£11,080 in 2026/27) |
| Tax reduction | £252 per year | 10% of allowance (£428–£1,108) |
| Income limits on recipient | Must be Basic rate (£27,491 in Scotland) | Can be any rate |
If either partner was born before 6 April 1935, check whether Married Couple's Allowance gives a larger saving. In most cases it does, since the maximum relief is £1,108 compared to Marriage Allowance's £252.
Frequently Asked Questions
Does Marriage Allowance use Scottish tax rates or UK rates?
The £252 saving is calculated at the UK Basic rate of 20%, not a Scottish-specific rate. However, Scotland's tax bands determine whether the recipient qualifies. The recipient must be a Basic rate taxpayer under Scotland's band structure (earning up to £27,491), which is narrower than England's equivalent. The actual tax credit is always 20% of £1,260 regardless of location.
Can I claim Marriage Allowance if my partner and I are separated?
Yes, you can still claim if you are legally married or in a civil partnership, even if you are separated — provided you haven't divorced or dissolved the partnership. However, once a divorce or dissolution is finalised, eligibility ends. There is no requirement to live together.
What happens if the lower earner has a small self-employment income?
Self-employment income counts towards the £12,570 threshold. If the transferor earns £8,000 from self-employment and £3,000 from a part-time job, their total income is £11,000 — still under £12,570, so they qualify. If their total income exceeds £12,570, they cannot transfer any allowance.
Can same-sex couples claim Marriage Allowance?
Yes. Marriage Allowance is available to all married couples and civil partners, regardless of gender. The same eligibility rules apply — one partner must earn below £12,570 and the other must be in the Basic rate band.
If I backdate my claim, how do I receive the refund?
HMRC sends backdated amounts as a cheque or BACS payment, usually within five weeks of processing. The current year's relief is applied through the recipient's PAYE tax code, reducing the tax deducted from their wages each month. If the recipient files Self Assessment, the relief appears on their tax return instead.
