Married or in a civil partnership? You might be owed £252.
If one of you earns under £12,570 and isn’t using their full personal allowance, you can transfer 10% of it to your other half. That’s Marriage Allowance, worth up to £252 a year off the higher earner’s tax bill.
The catch most people miss: the higher earner has to be a basic rate taxpayer, earning between £12,570 and £50,270. If they’re on 40%, it doesn’t apply.
It’s the lower earner who claims, and you can backdate it up to 4 years, so there could be more than one year’s worth sitting there.
