How Marriage Allowance works
Marriage Allowance lets you transfer £1,260 of your Personal Allowance to your husband, wife or civil partner. It can cut their Income Tax bill by up to £252 a year. It only works if one of you pays no Income Tax because your income is below the Personal Allowance, and the other pays tax at the basic rate.
The partner who gives away the allowance must have income of £12,570 or less. The partner who receives it must be a basic rate taxpayer. In England, Wales and Northern Ireland that means income between £12,571 and £50,270. In Scotland the top of the basic and intermediate bands is lower, so the upper limit used here is £43,662.
If either of you was born before 6 April 1935, you may be able to claim Married Couple's Allowance instead. See our Marriage Allowance guide for how to apply and what to watch for.
What this calculator assumes
- Both partners are married or in a civil partnership and live in the UK.
- Incomes are total taxable income for the 2026/27 tax year.
- The Scottish upper limit is the top of the intermediate band. Check GOV.UK if you are close to it.
- It does not check other conditions, such as being born before 6 April 1935, so use it as a first check, not a final answer.
