Married couples or those in a civil partnership could save up to £252 a year by claiming marriage allowance.
More than 2.1 million couples currently benefit from marriage allowance, but HM Revenue and Customs (HMRC) estimates that thousands more couples are missing out because they don’t realise they may be eligible, particularly couples where one partner has retired, has given up work to take on caring responsibilities, or is unable to work due to a long-term health condition.
People earning less than £12,570 a year can transfer up to £1,260 of their personal allowance to their higher-earning partner, to reduce the amount of tax they pay. They can backdate their claim to include any tax year up to 6 April 2018, which could be worth up to £1,242 in tax relief.
