Is My Tax Code Correct?

What NT Means
Tax code NT means no tax is deducted from this income. This is rare and applies in specific circumstances such as certain diplomatic roles, specific types of foreign employment income, or when HMRC has confirmed that the income is not taxable in the UK.
When This Code Is Used
NT is not a code you can request — it is applied by HMRC in limited circumstances. If you receive NT unexpectedly, verify with HMRC that it is correct. Receiving NT when you should be paying tax can create a large tax bill at year end when HMRC reconciles your records.
Impact on Your Pay
On NT, your gross pay equals your net pay (before NI). While this seems beneficial, ensure it is correct — if HMRC later determines tax was owed, you will face a lump-sum tax demand plus potential interest.
