FAQs
Can I backdate a Marriage Allowance claim?
Yes — you can backdate a claim for up to 4 tax years. If eligible for all 4 years, you could receive a lump sum of up to £1,008.
Does civil partnership qualify?
Yes. Marriage Allowance is available to both married couples and civil partners who meet the income criteria.
How do I apply?
The lower earner applies online at gov.uk/marriage-allowance. HMRC adjusts both tax codes — the lower earner's code drops and the higher earner's rises.
What happens if we separate?
Marriage Allowance stops in the tax year of separation or divorce. You need to notify HMRC.
