Tax Code Guide
M
Tax Code M (Marriage Allowance Recipient)
What does this code mean?
The M suffix means you are receiving a Marriage Allowance transfer from your spouse or civil partner. This adds 10% of their Personal Allowance (£1,260) to yours, giving you a total of £13,830 tax-free. This can reduce your tax bill by up to £252 per year.
Who gets this code?
The higher earner in a couple where one partner earns less than £12,570 and the other is a basic rate taxpayer. The lower earner transfers allowance to the higher earner.
