HMRC is reminding married couples and people in civil partnerships to sign up for the marriage allowance tax break.
The marriage allowance allows married couples and civil partners to share their personal tax allowances if one partner earns below the personal allowance threshold of £12,570 and the other is a basic rate taxpayer.
Eligible couples can transfer 10% of their tax-free allowance to their partner, a total of £1,260 for the tax year 2022/23, to reduce their tax bill by £252 a year.
Couples can apply at any time and can backdate their claims for up to four previous tax years, if eligible. If eligible, couples can backdate their claims for up to four previous tax years.
More than two million couples currently benefit from marriage allowance, but there are more who are still able to claim.
Angela MacDonald, HMRC's deputy chief executive, said:
"We want to ensure people are receiving the vital financial support at a time when they need it most.
"Married couples or those in civil partnerships could potentially receive tax relief worth up to £1,242, meaning extra cash in their pockets."
