Marriage Allowance for NHS Staff: Worth Up to £252 a Year

Marriage Allowance is one of the most under-claimed tax breaks in the UK. It suits many NHS households where one partner works part time on a low-band post, takes a career break, or is on maternity leave for part of the year. It is worth up to £252 a year, and you can usually backdate it.

How Marriage Allowance works

If you are married or in a civil partnership, the partner with the lower income can transfer £1,260 of their personal allowance to the other. That reduces the higher-earning partner's tax by up to £252 a year (20% of £1,260).

Who qualifies

• You are married or in a civil partnership. Couples who live together but are not married do not qualify.
• The partner transferring the allowance has income below the personal allowance, which is £12,570.
• The partner receiving it pays tax at the basic rate. In general they must not be a higher or additional rate taxpayer.

NHS examples

Part-time NHS staff on lower bands are often eligible to transfer:

So a Band 2 phlebotomist working 15 hours a week, married to a Band 6 nurse paying basic rate tax, could transfer £1,260 of allowance and cut the household's tax bill by £252 a year.

It also helps in years when one partner is on unpaid parental leave, has a career break, or is studying, as long as their income for the whole tax year is below £12,570.

How to claim

1. The partner with the lower income applies, usually online through GOV.UK.
2. You will need both partners' National Insurance numbers and some identity details.
3. HMRC changes the higher-earning partner's tax code, usually adding an "M" at the end, so they pay less tax each month.

The lower-income partner's tax code may show "N", meaning part of their allowance has been transferred.

Backdating

You can backdate a claim for up to four previous tax years, if you were eligible in those years. Backdated amounts are paid as a refund to the partner who receives the allowance. A backdated claim covering several years could be worth around £1,000 in total.

When to cancel

If the lower-income partner's income rises above the personal allowance, for example after increasing their hours, the claim may stop being worthwhile, because they would pay tax on the transferred amount. Review it when circumstances change. The partner who made the claim can cancel it.

Interaction with other allowances

Marriage Allowance is separate from the High Income Child Benefit Charge, tax-free childcare and other schemes. If either partner is close to a threshold for those, check each one separately. See our guides to the High Income Child Benefit Charge and tax-free childcare.

Common questions

Does NHS Pension income count? Yes. For retired members, pension income counts towards the personal allowance test.

Can we claim if one partner earns nothing? Yes, as long as the other partner is a basic rate taxpayer.

Do Scottish taxpayers qualify? Yes, if the receiving partner pays tax at the starter, basic or intermediate rate.

A worked backdating example

Suppose a Band 2 healthcare assistant has worked 15 hours a week for several years, earning below the personal allowance each year. Their spouse is a Band 6 nurse paying basic rate tax. They have never claimed Marriage Allowance.

If they were eligible in each year, they could claim:

That is up to about £1,260 in total, for a short online application.
