Marriage Allowance: How to Apply and Save on Your Tax Bill
Did you know that couples in the UK could save up to £252 per year through the Marriage Allowance?
It’s one of the most underclaimed tax reliefs available, yet thousands of eligible couples miss out every year. In this article, we’ll explain what the Marriage Allowance is, who qualifies, and how to apply.
What is Marriage Allowance?
Marriage Allowance is a government tax benefit that allows one partner to transfer part of their unused Personal Allowance to their spouse or civil partner.
The Personal Allowance is the amount of income you can earn tax-free each year. For the 2025/26 tax year, it’s £12,570.
If one partner earns below the Personal Allowance, they can transfer up to £1,260 of it to their higher-earning spouse or civil partner.
This reduces the higher earner’s tax bill by up to £252 per year.
Who Can Apply for Marriage Allowance?
You can apply if:
✅ You are married or in a civil partnership.
✅ One partner earns below the Personal Allowance (£12,570).
✅ The other partner earns between the basic rate tax band (£12,571 to £50,270).
❌ Couples living together but not married/civil partners are not eligible.
❌ Higher-rate taxpayers (over £50,270) cannot benefit.
How to Apply for Marriage Allowance
Applying is straightforward and can be done online in a few minutes.
- Visit the official HMRC Marriage Allowance application page.
- The partner with the lower income applies to transfer their allowance.
- You’ll need both partners’ National Insurance numbers and proof of identity.
- Once approved, HMRC will adjust your tax code and the saving will be reflected in your pay or tax return.
💡 Good to know:
- You can backdate your claim for up to four previous tax years.
- This could mean a tax rebate worth over £1,000 if you’ve been eligible but haven’t claimed.
Why Many Couples Miss Out
Many people assume Marriage Allowance only applies to low earners, but the truth is thousands of working couples qualify. Busy lives, lack of awareness, and confusion about eligibility mean millions of pounds go unclaimed every year.
