Many married couples and civil partners could be missing out on valuable tax savings available by claiming the Marriage Allowance. If your circumstances are suitable, this is a reminder to consider the Marriage Allowance, as a simple claim could reduce your tax bill by up to £252 during the 2026-27 tax year.

The Marriage Allowance allows a spouse or civil partner with income below their Personal Allowance to transfer £1,260 of that allowance to their partner. The standard Personal Allowance is £12,570 for the 2026-27 tax year. To qualify, the person receiving the transfer must normally be a basic-rate taxpayer and the higher-earning partner must also be a basic rate taxpayer. This generally means they have income between £12,571 and £50,270 during 2026-27. Different limits apply for Scottish taxpayers because of Scotland's separate Income Tax bands.

Although the transfer reduces the lower earner's Personal Allowance, the overall effect is usually beneficial for the couple as a whole. For many households, it provides an easy way to reduce the amount of Income Tax paid without making any changes to their working arrangements or income levels.

It is also worth remembering that claims can be backdated where eligibility existed in earlier years. Eligible couples can currently backdate a claim to 6 April 2022, which could result in a useful lump-sum repayment from HMRC.

Once a successful claim has been made, the allowance will usually continue automatically in future tax years unless it is cancelled or a change in circumstances affects eligibility. Couples whose income levels have changed recently may therefore wish to review whether they qualify and ensure they are not overlooking this tax-saving opportunity.
