What is the difference between Marriage Allowance and Married Couple’s Allowance?
Marriage Allowance and Married Couple’s Allowance sound similar but are separate reliefs. Marriage Allowance lets a lower earner transfer part of their Personal Allowance to their partner. Married Couple’s Allowance is an older relief available only where at least one spouse or civil partner was born before a certain date.

Marriage Allowance is the more widely available one: it works by letting the lower-earning partner pass a fixed slice of their unused Personal Allowance to the higher earner, reducing the couple’s overall tax. Most married couples and civil partners with the right income mix can consider it.
Married Couple’s Allowance is a separate, older relief that only applies where one of the partners was born before a set date. It works differently, reducing the tax bill by a proportion of a set amount rather than transferring Personal Allowance, and it is gradually being phased out as fewer people meet the age condition.
You cannot usually claim both at the same time, so it matters which one applies to you. The right relief depends on your ages and incomes, and the amounts and exact rules change over time, so check the current details on GOV.UK. Getting the correct one in place ensures you receive the benefit you are actually entitled to.
How to tell the two allowances apart
- Check your dates of birth. See whether either partner was born before the date that opens up Married Couple’s Allowance.
- Compare your incomes. Work out who is the lower and higher earner, which matters for whether Marriage Allowance helps you.
- Match to the right relief. Use your ages and incomes to identify which single relief applies to your situation.
- Claim through HMRC. Apply for the correct allowance via GOV.UK and confirm the change shows in your tax codes.
