NT Tax Code Meaning
The NT tax code means you pay no Income Tax on this income. Learn when it's used and if it's right for you.
What Does NT Mean?
NT stands for 'No Tax' and means you don't pay any Income Tax on this income source. Your employer or pension provider won't deduct any Income Tax from your pay, though you'll still pay National Insurance if you earn above the NI threshold (£12,570 per year).
How NT Tax Code Works
With an NT code, your gross pay equals your net pay (minus National Insurance). This is rare and only applied in specific circumstances approved by HMRC. You must still report this income on a tax return if required, and HMRC may review your tax situation annually.
How NT Affects Your Take-Home Pay
Example: £15,000 with NT code
- Gross income: £15,000
- Income Tax: £0 (NT code)
- National Insurance: ~£274 (on earnings above £12,570)
- Total deductions: £274
Take-home pay: £14,726 per year (£1,227 per month)
