NT means no tax is deducted from this income
Tax code NT tells your employer or pension provider to deduct no income tax at all from this income, whatever you earn. It is used in unusual cases such as certain non-residents, people in bankruptcy arrangements, some redundancy payments and a few pension schemes. National Insurance is usually still deducted as normal.
What does each part of NT mean?
- No income tax is taken from this source of income. National Insurance may still be deducted.
- NT is rare for ordinary employees. If you have it and do not know why, contact HMRC because you may still owe tax through Self Assessment.
- There is no S or C prefix, so HMRC treats you as living in England or Northern Ireland.
