Marriage Allowance: Claim £1,260 Back (Backdated 4 Years)
—
The Marriage Allowance lets a non-working or low-earning spouse transfer £1,260 of their Personal Allowance to their higher-earning partner. The recipient saves up to £252 per year on tax. Most eligible couples don’t claim it.
How It Works
Standard scenario: One spouse earns under £12,570 (Personal Allowance). The other earns above it but in basic-rate band.
The lower-earning spouse transfers £1,260 of their unused Personal Allowance to the higher-earning spouse.
Result: Higher-earning spouse pays 20% less tax on £1,260 = £252 saved per year.
Eligibility
- You must be married or in a civil partnership
- The transferring spouse: earns less than £12,570
- The receiving spouse: earns between £12,571 and £50,270 (basic rate band)
- Both must be UK taxpayers
It does NOT apply if the higher-earning spouse is in higher-rate or additional-rate band.
Backdating: Claim 4 Years Retroactively
You can backdate Marriage Allowance up to 4 tax years. This is the biggest missed money:
- 2026/27: £252
- 2025/26: £252
- 2024/25: £252
- 2023/24: £252
- Total backdated claim: £1,008
Plus ongoing future years.
How to Claim
Online at gov.uk (search “Marriage Allowance claim”). Simple form.
You’ll need:
- National Insurance numbers (both)
- ID for both partners
- Banking details for the refund
Backdated payments come via:
- Cheque
- BACS transfer
- Code adjustment if still in employment
Processing time: 2-3 weeks for current year, 8-12 weeks for backdated claims.
When to Cancel
Cancel Marriage Allowance if:
- The lower-earning spouse starts earning above £12,570
- You divorce or separate
- One spouse dies (transfer the year of death, then ends)
Failure to cancel can leave the higher-earning spouse with HMRC underpayment.
Variation: Married Couple’s Allowance
For couples where one was born before 6 April 1935. Different (and more generous) allowance. Rare in 2026.
What People Get Wrong
1. Both spouses must apply for transfer to happen. The lower-earning spouse initiates. The higher-earning spouse must accept on their tax return or HMRC online portal.
2. The transfer counts toward your annual allowance. The transferred £1,260 reduces what the lower-earning spouse can earn before tax. If they later get a part-time job paying £13,000, they’d pay tax on the extra £430.
3. It doesn’t compound — same amount each year. £252/year is the max regardless of the higher spouse’s marginal rate (basic rate only).
When NOT to Claim
- Higher-earning spouse is in higher-rate band
- One spouse is self-employed with fluctuating income
- The lower-earning spouse expects to start earning soon
In those cases, you’d file but be caught in unintended underpayment.
Combining with Other Allowances
- Personal Allowance: Available to all (£12,570 in 2026)
- Marriage Allowance: £1,260 transferred between spouses
- Married Couple’s Allowance: Only for pre-1935 couples
- Blind Person’s Allowance: Available to either spouse, transferable
These stack within the rules but Marriage Allowance is the most commonly missed.
The Numbers Many People Don’t See
UK statistics: about 4 million couples qualify for Marriage Allowance. About 1 million claim it.
That means 3 million couples leaving £252/year unclaimed = £756 million collectively per year.
If you’ve been married 5+ years and never claimed, check today. Backdated claims for 4 years can come to over £1,000 in cash.
💡 Pro Tip: Even if both spouses now earn above £12,570, you may have had years where one didn’t. Backdate those years.
