Printable version

1. Overview

Married Couple鈥檚 Allowance could reduce your tax bill by between 拢427 and 拢1,108 a year.

This page is also available in Welsh (Cymraeg).

You can claim Married Couple鈥檚 Allowance if all the following apply:

  • you鈥檙e married or in a civil partnership
  • you鈥檙e living with your spouse or civil partner
  • one of you was born before 6 April 1935

For marriages before 5 December 2005, the husband鈥檚 income is used to work out Married Couple鈥檚 Allowance. For marriage and civil partnerships after this date, it鈥檚 the income of the highest earner.

If you and your partner were born on or after 6 April 1935, you may be able to claim Marriage Allowance instead.

2. What you'll get

Married Couple鈥檚 Allowance could reduce your tax bill each year if you鈥檙e married or in a civil partnership.

For the 2024 to 2025 tax year, it could cut your tax bill by between 拢427 and 拢1,108 a year.

If you marry or register a civil partnership, you鈥檒l get the allowance on a pro-rata basis for the rest of that tax year.

If one of you dies or you divorce or separate, the allowance continues until the end of the tax year.

You can transfer your Married Couple鈥檚 Allowance to your spouse or civil partner.

If you and your spouse or civil partner are separated through circumstance rather than through a decision to formally separate, you can still claim Married Couple鈥檚 Allowance.
