Analysis shows that around 2m married couples are missing out on the Marriage Allowance, which offers tax relief of up to £252 annually. This allowance can be backdated for four years, potentially yielding a rebate of £1,260. To qualify, one partner must earn below £12,570, while the other must be a basic rate taxpayer. Laura Suter, director of personal finance at AJ Bell, said: “Many households are overlooking completely legitimate ways to earn tax-free income.”
