Tax Code 1131N Explained

What does this code mean?

1131N means your Personal Allowance is £11,310 after transferring £1,260 to your partner through Marriage Allowance. The "N" suffix confirms you are the transferor. This is beneficial only if you earn less than your full Personal Allowance, as the untaxed amount helps your partner save tax.

Who gets this code?

The lower earner who has opted to transfer part of their Personal Allowance to their spouse or civil partner.
