Question: how much do you have to earn to get marriage allowance?
Answer: Marriage Allowance lets you transfer £1,250 of your Personal Allowance to your husband, wife or civil partner. This can reduce their tax by up to £250 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 £12,500 or less.
