Marriage Allowance

If you’re married or in a civil partnership and one of you earns less than £11,850 you could benefit from the Marriage Allowance

Marriage Allowance lets you transfer £1,190 of your Personal Allowance to your husband, wife or civil partner - if they earn more than you. This reduces their tax by up to £238 in the tax year (6 April to 5 April the next year). To benefit as a couple, you (as the lower earner) must have an income of £11,850 or less. Your partner must be a basic rate tax payer. 

You can backdate your claim to include any tax year since 6 April 2015 that you were eligible for Marriage Allowance.

To claim you and your partner must be born on or after 6 April 1935 and neither of you pay tax at the higher or additional rate.

For example:

You earn £8,000 a year, and your Personal Allowance for 2018/19 is £11,850.

Your partner also has a Personal Allowance of £11,850 and earns £15,000 a year. They will usually pay 20 per cent income tax on everything they earn over £11,850.

Transferring £1,190 of your Personal Allowance to your partner will reduce their tax by £238 this year.
