What is the marriage allowance?

Marriage allowance is a tax perk available to couples who are married or in a civil partnership, where one low earner can transfer £1,260 of their personal allowance to their partner.

The higher-earning spouse, who must be a basic-rate taxpayer, will then receive a tax credit equivalent to the amount of personal allowance that has been transferred to them. This is deducted from the amount of tax they would usually have to pay.

To be eligible:

  • The low earning partner’s income before tax must be less than the personal allowance - which in 2022-23 is £12,570 (unchanged from 2021-22).
  • The higher-earning partner’s salary must fall between the threshold for the basic-rate of income tax, i.e between £12,571 and £50,270.

Scottish income tax has different bands and rates; you can claim marriage allowance if the higher-earning partner's salary falls between the Scottish starter, basic rate or intermediate rate of tax, so essentially the higher-earning partner’s salary would have to be less than £43,662. 


How does marriage allowance work?

To benefit from the marriage allowance, the lower earner must apply to HMRC to request any unused personal allowance can be transferred to their spouse.

Those earning less than the personal allowance can transfer a maximum of £1,260 in 2022-23 to their partner’s allowance. If you decide to transfer any of your unused personal allowance, you must transfer all of it.

If you earn less than £11,310 (the personal allowance minus £1,260), you can do this without being liable to pay any tax.

In 2022-23, those earning above £11,310, but below £12,570 can still transfer £1,260 of allowance, but will become liable to pay tax on any income in excess of £11,310. Their partner still makes a tax saving, but the extra tax they pay reduces the overall level of saving made by the couple.

This allowance will transfer to the spouse automatically every year unless you contact HMRC to cancel it, or your marriage comes to an end (either through divorce or death).

Who qualifies for marriage allowance?

In order to qualify for the marriage allowance you must fulfill the following criteria:

  • Be married or in a civil partnership.
  • Be born after 5 April 1935. If one or both of the couple are born before this date, you should claim the ‘married couple’s allowance’ instead. 
  • Have one partner with a salary below the personal allowance, and one partner earning more than the personal allowance paying the basic rate of income tax.

If your partner died after 5 April 2018

If your partner has died since 5 April 2018, it is possible to backdate your marriage allowance claim to include any tax year since 5 April 2018 that you were eligible to receive it.

To receive backdated marriage allowance, phone the HMRC Income Tax helpline. If your partner was the lower earner in the couple, the person responsible for managing their tax affairs will need to be the one to call HMRC.

Marriage allowance: your questions answered

Not sure how the marriage allowance works or how it applies to your situation? Find answers to commonly-asked questions about the marriage allowance and how it applies.

Can the marriage allowance be backdated?

Yes, you can backdate your claim for up to four years. 

Will the marriage allowance change my tax code?

Usually, yes. The recipient partner’s tax code will usually change to ‘M’, to show they are receiving marriage allowance from their spouse. 

If the partner who transferred their personal allowance is in employment, their tax code will change to ‘N’, showing they have elected to use the marriage allowance.

Is marriage allowance taxable?

No, marriage allowance is a way of paying less tax if one partner is not using all or any of their personal allowance.

How does the marriage allowance get paid?

Marriage allowance isn’t something that’s paid to you – instead, it’s a tax relief for a partner who pays the basic tax rate.

They’ll be taxed on a smaller proportion of their salary, so the extra money will be received whenever they get paid each week or each month.

However, if you’ve applied for backdated marriage allowance from previous years, this amount will be sent by cheque in the post.

How do I cancel my marriage allowance?

To cancel a marriage allowance transfer, you should contact HMRC – you can do this online or by calling 0300 200 3300.

The marriage allowance arrangement will automatically be cancelled if the marriage ends through divorce or death.

Can I claim marriage allowance if I'm not working?

Yes, if you’re not working you can transfer 10% of your personal allowance to your partner – but they must be earning, and be a basic rate taxpayer.

Can self-employed people claim the marriage allowance?

Yes, as long as one partner earns less than £12,570 and the other earns between £12,571 and £50,270. 

If the recipient partner files a self-assessment tax return, marriage allowance will reduce their self-assessment bill.

Can you claim marriage allowance while on maternity leave?

Yes. If, while on maternity leave, your income falls below £12,570, you can apply to transfer 10% of your personal allowance to your spouse.

Can higher rate taxpayers get marriage allowance?

No, marriage allowance is only for basic rate taxpayers with partners who earn less than the personal allowance.

What if I stop being eligible for marriage allowance part-way through a tax year?

If your circumstances change – ie. perhaps the non-taxpaying partner starts earning more than £12,570 and is then required to pay basic rate tax – HMRC will not know until the end of the tax year.

At this time, it will send a P800 calculation form and recover any tax you owe by adjusting your tax code for the next tax year, or by adding it to your self-assessment tax bill if you’re self-employed.

Married couple's allowance


Easy to confuse with marriage allowance, due to its similar name, married couple’s allowance is a very different tax break.

One or both halves of the couple must be born before 5 April 1935 to be eligible, and means you and your spouse can reduce your tax bill by up to 10%, depending on your earnings.

Inheritance tax


When one of you dies, the surviving spouse won't have to pay inheritance tax (IHT) on their partner's assets.

They'll also inherit their spouse's unused inheritance tax allowance, potentially doubling their IHT allowance when they pass on assets to the next generation.

Tax on savings and investments


If one of you pays tax at a higher rate, a simple way to save tax is to transfer some of your savings and investments to the person paying the lower rate.

There are no laws against spending or investing income earned from a spouse's investment.

The transfer has to be a genuine gift, though. You can't demand the money back if you get divorced or change your mind.

If you have investments in joint names, you'll each automatically pay tax on half the income - even if you own them in unequal shares.

Capital gains tax


Married couples each have their own capital gains tax (CGT) allowances, but transfers between spouses are exempt from CGT.  

This means it's possible to transfer assets between one another to make the most of both spouses' annual CGT allowance. Transferring an asset into your joint names will have the same effect.

Once again, the transfer must be a genuine gift.
