Wage0T Tax Code — What It Means
No Personal Allowance is applied, and your income is taxed across the normal basic, higher and additional rate bands.
How 0T changes your pay on a £30,000 salary
| Code | Income tax / year | Per month | Take-home / month* |
|---|---|---|---|
| Standard 1257L | £3,486 | £291 | £2,210 |
| 0T | £6,000 | £500 | £2,000 |
*Take-home per month here reflects income tax only; National Insurance and any student loan or pension are separate.
Why you might have the 0T code
- Your tax-free Personal Allowance has already been used up elsewhere.
- You started a new job without giving your employer a P45 or the details needed to set a code.
- Your income is high enough that the Personal Allowance has been fully tapered away.
How to fix a wrong code
If 0T is a temporary code after starting a job, give your employer your P45 or complete a starter checklist, or contact HMRC to have the correct code issued.

General information, not advice. Estimates assume the standard 1257L tax code and typical circumstances; your payslip may differ by a pound or two because HMRC payroll software truncates at each step.
