HMRC has today revealed that March is the most popular month for Marriage Allowance applications, with almost 70,000 couples applying in March last year. And with the option to backdate their claim for the previous 4 tax years, eligible couples could receive a lump-sum payment worth more than £1,000, in addition to reducing their tax bill for the 2023 to 2024 tax year by up to £252.
People can find out in 30 seconds if they are eligible by using the online Marriage Allowance Calculator.
Marriage Allowance saves couples money by allowing the lower or non-earner to reduce the amount of tax their partner pays by transferring up to £1,260 of their Personal Allowance to their husband, wife or civil partner.
The easiest way to claim Marriage Allowance is online via GOV.UK.
Marriage Allowance lets individuals transfer up to 10% of their tax-free Personal Allowance. The maximum amount that can be transferred to their husband, wife or civil partner is dependent on the Personal Allowance for that tax year.

In Scotland, couples can benefit from Marriage Allowance if the partner with the higher income pays income tax at the starter, basic rate or intermediate rate – which typically means their income is between £12,571 and £43,662.
