Money Saving Expert Martin Lewis has told millions of Brits they could be owed up to £1,000 - but don't even realise it.
According to Martin, a large number of people in the UK are yet to claim a tax break of up to £250 per year - just for being married or in a civil partnership.
Speaking on a special edition of The Martin Lewis Money Show Live, the finance expert explained: "If you are a married couple or in a civil partnership - not common law, just living together doesn’t count - and one of you is a non-taxpayer, the other is a basic 20% rate taxpayer, then this person can give 10% of their tax-free allowance to the other person.
"You apply online at GOV.Uk and it’s worth about £250 this year, but you can go back four years. The past years are done by cheque, this year is done by tax code change. It’s very lucrative, there are over one million people who aren’t claiming it."
How does Marriage Tax Allowance work?
If one partner earns less than their personal allowance, which is £12,570 for the tax year 2021/22 and the other partner is a basic rate taxpayer (earning £12,571 to £43,662) then the lower earner can transfer 10% of their personal allowance to the higher earner and reduce the tax bill of the higher earner.
This transfer means the higher-earning partner now has a higher personal allowance and will pay less tax on their total earnings.
