Marriage Allowance Calculator
See if you're eligible to save up to £252 per year by transferring personal allowance to your spouse.
How Marriage Allowance Works
If one partner earns under £12,570 and the other is a basic rate taxpayer (earning under £50,270), you can transfer £1,260 of the lower earner's personal allowance to the higher earner. This saves the higher earner £252 per year (£1,260 × 20%).
Eligibility
You must be married or in a civil partnership. The lower earner must earn under £12,570. The higher earner must be a basic rate taxpayer (earning under £50,270). You can also backdate claims for up to 4 years, potentially worth up to £1,260 total.
