Marriage Allowance lets you transfer £1,100 of your Personal Allowance to your husband, wife or civil partner.
This can reduce their tax by up to £220 every tax year (6 April to 5 April the next year).
To benefit as a couple, you need to earn less than your partner and have an income of £11,000 or less.
If you were eligible for Marriage Allowance in the 2015 to 2016 tax year, you can backdate your claim to 6 April 2015 and reduce the tax paid by up to £432.
