Married couples living across the UK could be missing out on £1,242, financial guru Martin Lewis has warned.
The ITV star and MoneySavingExpert founder predicts that some two million Britons aren't claiming marriage tax allowance, which in essence allows workers to transfer £1,260 of their personal allowance to a partner, to shave their yearly tax bills.
A personal allowance is best defined as the amount that a person can receive before they start paying tax each financial year.
