Marriage Allowance: is it time to review your household’s tax position?
Published 28 October 2026. A practical guide to existing GOV.UK rules checked this morning. This article does not describe new Autumn Budget measures.
Has one partner reduced their hours, retired or experienced a fall in income? That is a useful prompt to review Marriage Allowance and consider both partners’ tax positions together.
How does it work?
An eligible spouse or civil partner can transfer £1,260 of Personal Allowance, potentially reducing the recipient’s tax by up to £252 a year. The transferor normally earns below £12,570 and the recipient pays basic-rate tax; Scotland also allows the starter and intermediate rates. Unmarried couples who are not civil partners cannot claim.
Check the combined outcome
The transferor’s allowance falls, which can create a tax liability for them. The full £252 is not a guaranteed household saving. Compare the couple’s combined tax before applying.
Who makes the claim?
Where both partners have wages only, the lower earner should normally apply. Other income, such as dividends or savings interest, can require further assessment. In Self Assessment, the person transferring the allowance completes the relevant section. If both file returns, the transferor should submit theirs at least three days before the recipient.
Prepare for a useful review
Bring income summaries for both partners, current tax codes and details of previous claims. Note changes in work or income so the review reflects your circumstances rather than a single month’s payslip.
A ZipTax consultation can help you assess whether this relief is appropriate and discuss the correct claim route. The outcome depends on your individual figures.
