Moneysavingexpert founder Martin Lewis is urging married couples to apply for a tax break before the upcoming deadline.
As many as 2.4 million married people are eligible for up to £1,150 - IF applications are made before April 5.
Marriage Allowance lets you transfer £1,250 of your Personal Allowance to your husband, wife or civil partner. This reduces their tax by up to £250 - and you can claim back five year's worth of allowance.
Here's the criteria to qualify:
- You must be married or in a civil partnership
- One of you must be a non-taxpayer (ie earning less than £12,500 between 6 April 2019 and 5 April 2020) whilst the other must be a basic rate taxpayer (20% rate only).
- You both must have been born on or after 6 April 1935
If successful, you could claim money back for five separate tax years - accumulating as much as £1,150.
