The Marriage Allowance is a simple way for couples to save on tax.

You transfer £1,260 (10%) of your Personal Allowance to your husband, wife, or civil partner if they earn more than you.

In 2024/25 tax year, this reduces their tax by up to £260.

Are we eligible?

Yes, if:

How much can my partner get?

You can backdate your claim by up to four years:

  • 2018/19 – £238
  • 2019/20 – £250
  • 2020/21 – £250
  • 2021/22 – £260
  • 2022/23 – £260
  • 2023/24 – £260

So if you claim now and backdate, your partner/spouse can get up to £1,020.
