Marriage Allowance

If you’re married or in a civil partnership and one of you earns less than £11,500 you could benefit from the Marriage Allowance

Marriage Allowance was introduced from April 2015. It allows a spouse or civil partner to transfer 10% (£1,150) of their Personal Allowance (£11,500 for the 2017/18 tax year) to their partner, provided that both were born on or after 6 April 1935 and neither pay tax at the higher or additional rate. 

This can benefit couples where a spouse does not currently use their full Personal Allowance and reduce their partner’s tax by up to £230 for the current tax year (£212 for 2015/16, £220 for 2016/2017).


You earn £8,000 a year, and your Personal Allowance for 2017/18 is £11,500.

Your partner also has a Personal Allowance of £11,500 and earns £15,000 a year. They will usually pay 20% income tax on everything they earn over £11,500. Transferring £1,150 of your Personal Allowance to your partner will increase their Personal Allowance to £12,650 (£11,500 plus £1,150), which means they won't pay income tax on their first £12,650 of earnings. This will reduce your partner's tax liability by £230.

Your Personal Allowance will be reduced to £10,350 (£11,500 minus the £1,105 you transferred to your partner).
