Can additional rate taxpayers claim Marriage Allowance?

Full answer

Marriage Allowance is a valuable but narrowly targeted relief, and understanding exactly who qualifies avoids a wasted application or an unexpected clawback later. **The basic mechanics** Marriage Allowance lets one spouse or civil partner transfer £1,260 of their unused Personal Allowance to their partner, reducing the receiving partner's tax bill by up to £252 a year (20% of £1,260) -- it is designed for couples where one partner earns too little to use their full Personal Allowance. **Who is excluded** To qualify, the person transferring the allowance must normally not be liable for Income Tax at all, or only pay it at the basic rate after the transfer, and -- critically -- the person RECEIVING the transferred allowance must not be a higher rate (40%) or additional rate (45%) taxpayer. If the receiving partner's income means they pay tax above the basic rate band (broadly, above £50,270 for most of the UK), they cannot benefit from Marriage Allowance at all, even if their partner has substantial unused Personal Allowance. **Why the higher/additional rate exclusion exists** The policy intent is to help couples on modest to middle incomes where one partner earns below the Personal Allowance -- allowing higher and additional rate taxpayers to receive the transfer would extend the relief to significantly higher-income households, which HMRC excludes by design, regardless of how low the transferring partner's own income might be. **Worked example -- valid claim** One partner earns £9,000 a year (well under the £12,570 Personal Allowance, using only £9,000 of it and leaving £3,570 unused), and the other partner earns £35,000 a year (a basic rate taxpayer). The lower earner can transfer £1,260 of their unused allowance to the higher-earning partner, reducing the receiving partner's tax bill by £252 a year, since the receiving partner remains comfortably within the basic rate band even after adding the transferred allowance. **Worked example -- claim not permitted** If the higher-earning partner instead earns £55,000 a year (already in the higher rate band), Marriage Allowance cannot be claimed at all, regardless of how little the other partner earns, because the receiving partner is not a basic rate taxpayer. **What happens if income changes after a claim starts** If the receiving partner's income rises during the tax year and they become a higher rate taxpayer partway through, HMRC can cancel the Marriage Allowance claim, and any transferred allowance already used may need to be repaid through an adjustment to their tax code or a Self Assessment calculation for that year, so a couple close to the higher rate threshold should monitor this carefully. **Scottish taxpayers** Because Scotland has different income tax bands (including an intermediate rate), the specific threshold at which a Scottish taxpayer becomes ineligible to receive Marriage Allowance is based on Scottish higher rate rules, not the rest-of-UK £50,270 figure, so Scottish couples should check the Scottish-specific threshold rather than assuming the rUK figure applies. **Practical tip** Before applying, check both partners' expected income for the full tax year, not just their current salary, since a bonus, pay rise, or change in circumstances that pushes the receiving partner into the higher rate band partway through the year can invalidate the claim and create a tax adjustment to unwind later.
