Marriage Allowance can be backdated by up to four years to the 2020/21 financial year.
Martin Lewis encourages married couples under 90 to claim the Marriage Allowance tax break, which can provide up to £1,260. The deadline for the 2024/25 tax year is April 5, 2024. Claims can be backdated up to four years, potentially offering a refund of £1,260. Couples should claim online for the current year and use a form from GOV.UK for previous years. Postal claims require signed-for delivery. Eligibility requires being married or in a civil partnership, both born after April 5, 1935, one earning under £12,570, and the other a basic-rate taxpayer. Details are available on MoneySavingExpert.com. HMRC's helpline is 0300 200 3300 for those whose partners have passed since 2020.
