UK Marriage Allowance 2026/27: £1,260 Transfer, £252 Tax Saving
UK Marriage Allowance guide 2026/27 - transfer £1,260 of unused Personal Allowance between spouses to save the recipient up to £252/year of Income Tax. Eligibility, how to claim via Personal Tax Account, 4-year backdating, auto-renewal, civil partnership coverage, and worked examples.
How Marriage Allowance works
The Marriage Allowance (MA) is a UK Income Tax relief introduced from 6 April 2015 under Section 11 Finance Act 2014. It allows a spouse or civil partner with unused Personal Allowance to transfer £1,260 of that allowance to their partner, reducing the recipient's Income Tax bill by 20% × £1,260 = £252 per year. The transfer amount is fixed at £1,260 (10% of the £12,570 Personal Allowance, rounded), and has not changed since the £1,260 level was set for 2020/21.
Mechanically: the lower spouse's coded Personal Allowance drops from £12,570 to £11,310 (suffix "N" added to tax code). The higher spouse's coded PA increases from £12,570 to £13,830 (suffix "M" added). The lower spouse loses £252 of tax-free shelter — which is typically irrelevant because they had below-PA income anyway. The higher spouse saves £252 of Income Tax at 20% basic rate. Net family saving: £252/year.
Eligibility requires both spouses to be married or in a civil partnership, the lower spouse to have income below the £12,570 Personal Allowance, and the higher spouse to be a basic-rate taxpayer (income £12,5701-£50,270). Higher-rate and additional-rate spouses are excluded. Couples where either spouse was born before 6 April 1935 use the more generous Married Couple's Allowance instead.
Worked eligibility scenarios
| Couple | Lower income | Higher income | Eligible? | Annual saving | Notes |
|---|---|---|---|---|---|
| Stay-at-home parent + basic-rate earner | £0 | £35,000 | YES | £252 | Classic eligible scenario. Lower spouse has full unused £12,570 PA. Transfer £1,260 to higher spouse who pays 20% basic rate. Saves £252/year. |
| Part-time worker + basic-rate earner | £8,000 | £45,000 | YES | £252 | Lower spouse has £4,570 of unused PA after their own £8k income - still enough to transfer £1,260. Higher spouse at 20% saves £252. |
| Pensioner couple — one drawing State Pension only | £11,500 | £30,000 | YES | £252 | Lower spouse on basic State Pension £11.5k has £1,070 of unused PA but Marriage Allowance still allows £1,260 transfer (HMRC waives the strict cap when income is close to PA). |
| Higher-rate spouse — NOT eligible | £5,000 | £70,000 | NO | - | Higher spouse exceeds £50,270 higher-rate threshold. Marriage Allowance is restricted to basic-rate band recipients. |
| Two working spouses both basic-rate | £25,000 | £40,000 | NO | - | Lower spouse income exceeds £12,570 PA — they would lose tax on transferring the unused portion (only the £25k-£12,570 = £12,430 is taxed currently; reducing PA to £11,310 would push £1,260 into tax). Net zero or negative outcome. |
| Scottish Starter-rate spouse + basic-rate recipient | £14,000 | £40,000 | YES | £251 | Scottish lower spouse pays 19% Starter rate on £1,430 (£14k - PA), so transferring £1,260 reduces their tax by £239 (was 19% on £1,430 = £272, now 19% on £170 = £32). Higher spouse saves £252. Net: lower spouse loses £33 of refund, higher gains £252 — net £219 family saving. |
Backdating up to 4 previous years
HMRC allows backdating up to 4 previous tax years from the year of claim. A first-time claim in 2026/27 can retrospectively claim for:
- 2022/23 (£252 refund)
- 2023/24 (£252)
- 2024/25 (£252)
- 2025/26 (£252)
- 2026/27 (£252 — current year, applied via tax code change)
Maximum single-claim refund: £1,260. Backdating refund typically paid as bank transfer 5-10 working days after HMRC processes the claim. Eligibility tests apply year-by-year: both spouses must have met the income criteria in each backdate year. Backdating works even after one spouse has died (the survivor claims retrospectively for the years before the death where both spouses met the criteria).
How to apply - 3 routes
- Personal Tax Account (recommended) — gov.uk/personal-tax-account. Sign in with Government Gateway, select "Marriage Allowance", confirm spouse details, submit. Takes 5 minutes. The lower-earning spouse initiates the transfer (the system needs their authorisation as the spouse giving up some PA).
- HMRC online form — gov.uk/apply-marriage-allowance. Same process without Personal Tax Account sign-in. Used by couples without Government Gateway accounts.
- Phone HMRC — 0300 200 3300 (Monday-Friday 8am-6pm). Slowest route, used only if online services unavailable.
Processing typically 6-12 weeks. Recipient's tax code changes to "M" suffix (e.g. 1383M); lower spouse's code changes to "N" suffix (e.g. 1131N). Auto-renews each tax year unless cancelled. Cancel anytime via Personal Tax Account, taking effect from start of the next tax year.

Frequently asked questions
How much is Marriage Allowance worth?
For 2026/27 the Marriage Allowance transfers £1,260 of unused Personal Allowance from the lower-earning spouse to the higher-earning spouse, saving the recipient up to £252 of Income Tax per year (£1,260 × 20% basic rate). Across both spouses combined, the net family saving is up to £252 provided the lower spouse has at least £1,260 of unused Personal Allowance (or is comfortably below the £12,570 PA threshold). The transfer can also be backdated up to 4 previous tax years, so a first-time claim in 2026/27 can recover up to 5 years × £252 = £1,260 in one go.
Who is eligible for Marriage Allowance?
Three conditions all required: (1) You are married or in a civil partnership (cohabiting partners NOT eligible regardless of length of relationship), (2) the lower-earning spouse has total income below the £12,570 Personal Allowance (or close to it - HMRC allows the £1,260 transfer even if it would push the lower spouse marginally above PA), (3) the higher-earning spouse is a basic-rate taxpayer with total income at or below £50,270. Higher-rate and additional-rate spouses are NOT eligible to receive Marriage Allowance. Both spouses must have been born on or after 6 April 1935 (older couples use Married Couple's Allowance instead, which is more generous). You can be UK-resident, Crown servant overseas, or in a partial-year residence situation - rules are flexible.
How do I apply for Marriage Allowance?
Three application routes. (1) Personal Tax Account (gov.uk/personal-tax-account) - sign in with Government Gateway, select "Marriage Allowance", confirm spouse details, submit. Takes 5 minutes. The lower-earning spouse must initiate the transfer. (2) HMRC online form at gov.uk/apply-marriage-allowance - same process without Personal Tax Account sign-in. (3) By phone on 0300 200 3300 (Monday-Friday). Phone route is slower and used only if you can't access online services. After applying: HMRC processes typically within 6-12 weeks. The recipient spouse's tax code changes to include the "M" suffix (e.g. 1383M instead of 1257L), increasing their take-home from the next pay period onwards. The lower spouse's code changes to "N" suffix (e.g. 1131N), reducing their PA by £1,260 - usually irrelevant because they were below PA anyway. Marriage Allowance auto-renews each tax year unless circumstances change or you actively cancel.
Can I backdate Marriage Allowance?
Yes - HMRC allows backdating up to 4 previous tax years from the year of claim. A first-time claim in 2026/27 can claim retrospectively for 2022/23, 2023/24, 2024/25, 2025/26, AND 2026/27 - five years total. Maximum saving on full backdating: 5 × £252 = £1260 (approximately, as the transfer amount and rate vary slightly across years). HMRC backdating refund is typically paid as a single lump sum via bank transfer (5-10 working days after the claim is processed). To backdate: when applying via Personal Tax Account, the system asks "How many previous years do you want to claim for?" - tick all applicable years. Backdate eligibility tests apply year-by-year: both spouses must have met the income criteria in each backdate year. Backdating works even after one spouse has died (the survivor can claim retrospectively for the years before the death where the criteria were met).
What is the difference between Marriage Allowance and Married Couple's Allowance?
Two completely different reliefs. Marriage Allowance (MA) is the £1,260 transfer-of-Personal-Allowance scheme that saves up to £252/year, available to couples where BOTH spouses are born on or after 6 April 1935. This is the standard relief most couples use. Married Couple's Allowance (MCA) is a separate older relief for couples where at least ONE spouse was born BEFORE 6 April 1935 (currently aged 91+). MCA is more generous - a £11,700 maximum allowance for 2026/27 worth up to £1,170 at 10% (the MCA-specific rate). MCA tapers down to a minimum £4,530 allowance (worth £453) by an adjusted-net-income taper. Eligibility for MCA excludes you from Marriage Allowance - you take whichever you qualify for, never both. Around 1.7 million UK couples claim MA each year; only around 60,000 claim MCA (the older cohort).
What happens if my income changes mid-year?
Marriage Allowance is annual - eligibility tested at the end of the tax year. If the lower spouse's income rises above £12,570 during the year, or the higher spouse moves into higher rate (£50,271+), the Marriage Allowance is still applied for that tax year unless you cancel. HMRC reconciles the actual position at year-end via the Personal Tax Account or P800 letter. If circumstances ended the eligibility (e.g. lower spouse got a substantial pay rise), HMRC may issue a clawback through the next year's tax code or via a one-off SA liability. To avoid surprises, cancel Marriage Allowance immediately if circumstances change materially - via Personal Tax Account, online form, or phone. Cancelling takes effect from the start of the next tax year (not retroactively). The lower spouse can cancel via Personal Tax Account at any time; HMRC then issues coding notice to the recipient spouse's employer.
Can I claim Marriage Allowance if my partner died?
Yes - a surviving spouse can claim Marriage Allowance retrospectively for years when their deceased spouse met the criteria, going back up to 4 previous tax years from the year of claim. The claim is made by the surviving spouse (NOT the deceased's estate) via Personal Tax Account or the standard application route. The retrospective refund covers the years the deceased was alive AND below the PA threshold. The relief does not continue forward into years after the death - Marriage Allowance requires a marriage / civil partnership at the time of the claim period. Practical scenario: husband (basic-rate earner £30k) and wife (stay-at-home, no income) were married 2015-2024 when wife died. Husband can claim Marriage Allowance for 2022/23, 2023/24, 2024/25 in 2026/27 = £756 refund. Cannot claim 2025/26 onwards because wife was deceased before tax-year start.
Does Scottish Income Tax affect Marriage Allowance?
Marriage Allowance operates at UK basic-rate (20%) level regardless of Scottish bands. A Scottish basic-rate-band recipient (paying 20% Scottish basic) saves the same £252/year as a rest-of-UK recipient. A Scottish Intermediate-rate (21%) recipient saves slightly MORE - £1,260 × 21% = £265 - because their marginal rate is 1 percentage point above the UK basic. A Scottish Higher-rate (42%) recipient is NOT eligible because Marriage Allowance is restricted to basic and Intermediate band recipients (technically: those who are not Higher-rate taxpayers in either UK or Scottish bands). The Scottish 19% Starter rate creates a small complication: a Scottish lower spouse paying 19% on £1,430 of income above the £12,570 PA who transfers £1,260 loses 19% of the transferred amount they would have used (£239 less tax saved by lower spouse) while higher spouse gains £252. Net family saving: £13/year less than the rest-of-UK equivalent.
Is Marriage Allowance affected by Universal Credit or benefits?
Marriage Allowance doesn't directly affect benefit entitlement because the transferred PA isn't "income" for benefit-means-testing purposes. However, the recipient spouse's slightly-lower take-home tax COULD theoretically affect Universal Credit work allowance calculations - in practice the effect is small (~£21/month of additional net income to a working recipient spouse), and the UC means-test treats this as standard earnings increase, taking back 55p per £1 of additional take-home. Net family benefit retained: £113/year for UC-claiming couples (the 45% retained after UC taper). For Pension Credit, the lower spouse's income reduction by £1,260 may marginally reduce their Pension Credit Guarantee Credit if they were receiving it. Specialist benefits advice recommended for any complex case involving Universal Credit, Pension Credit, or Housing Benefit alongside Marriage Allowance.
What about civil partnerships and same-sex marriage?
Civil partnerships qualify for Marriage Allowance on identical terms to marriage. Same-sex marriages (legalised in England, Wales and Scotland from 13 March 2014) qualify on identical terms to opposite-sex marriages. Civil partnerships were extended to opposite-sex couples in December 2019 - all combinations of marriage/civil-partnership AND opposite-sex/same-sex qualify identically. The terminology in HMRC forms uses "spouse or civil partner" throughout. International marriages and civil partnerships recognised by UK law (per the Marriage (Same Sex Couples) Act 2013 and Civil Partnership Act 2004) also qualify. Cohabiting couples without legal marriage or civil partnership are NOT eligible regardless of length of relationship or shared children - this is one of the most-criticised structural features of UK personal tax, but the rule is statutory and HMRC has no discretion to extend.
When does Marriage Allowance stop being worth claiming?
Five scenarios where MA is NOT worthwhile or net-negative. (1) Lower spouse income above PA: transferring £1,260 pushes £1,260 of their income into 20% taxable, losing £252 of their refund - net zero. (2) Higher spouse income above £50,270: not eligible (Higher rate band excludes Marriage Allowance). (3) Higher spouse not actually paying tax (e.g. PA = full income): no tax to reduce, MA has no benefit. (4) Lower spouse has any Income Tax liability (rare scenarios: deemed-disposal, withdrawn pension over PA in same year): the transfer cuts into their own PA shelter. (5) Pension Credit Guarantee Credit recipient: marginal Pension Credit may reduce in line with PA reduction. For most "stay-at-home spouse + working basic-rate spouse" couples the answer is unambiguously YES claim - £252/year for 5 minutes of online form is among the highest hourly returns in UK personal tax planning.
How do I cancel Marriage Allowance?
Cancel via Personal Tax Account (gov.uk/personal-tax-account) - sign in, navigate to "Marriage Allowance" section, select "Stop receiving" or "Stop transferring". Cancellation takes effect from the START of the next tax year (6 April), not retroactively. Mid-year changes require contacting HMRC by phone (0300 200 3300) and explaining the circumstances - HMRC may make an in-year code adjustment if the eligibility has clearly ended (e.g. divorce decree absolute issued, civil partnership dissolution finalised). After cancellation, HMRC issues new coding notices: lower spouse's "N" suffix returns to standard 1257L; higher spouse's "M" suffix returns to standard 1257L. If you cancel partway through a tax year, the tax saving for that year is retained but no further years apply. Re-applying later restarts the auto-renew cycle from the year of re-application.
