Tax code decoder
NT
No tax is taken off this income
What each part means
- NT means no tax at all is deducted from this source. It is rare, and normally used where the income is not taxable in the UK, for example for some non-residents or where tax is dealt with another way.
Does it look right?
Rare, and normally only right in specific circumstances.
- If you did not expect it, ask HMRC why. Paying no tax now usually means a bill later if the code is wrong.

Sign in to your Personal Tax Account. Under PAYE you can see what HMRC thinks you earn from each source and what is in your code, and you can correct most of it yourself.

If you would rather talk to someone, ring the Income Tax helpline on 0300 200 3300 with your National Insurance number to hand. Ask them to explain each line of your code and to send you a P2 if you have not had one.

Once HMRC changes your code they send the new one to your employer or pension provider. Any tax you overpaid earlier in the year comes back automatically in your next pay on a cumulative code.
