About the Marriage Allowance Calculator
Use this UK Marriage Allowance calculator to check whether you may qualify and estimate your tax saving for the 2026/27 tax year.
Enter both partners' annual incomes to see if Marriage Allowance is available, who should transfer allowance to whom, and how much Income Tax you could save as a couple.
Marriage Allowance is designed for couples where one partner earns below the Personal Allowance and the other pays tax at the basic rate. The transferable amount is £1,260, which can reduce tax by up to £252 a year.
This calculator provides an estimate for married couples and civil partners in England, Wales and Northern Ireland. It does not cover every HMRC eligibility rule, such as residency or date of birth conditions.
