WageD0 Tax Code — What It Means
All the income from this job or pension is taxed at the higher rate, with no Personal Allowance applied against it.
How D0 changes your pay on a £30,000 salary
| Code | Income tax / year | Per month | Take-home / month* |
|---|---|---|---|
| Standard 1257L | £3,486 | £291 | £2,210 |
| D0 | £12,000 | £1,000 | £1,500 |
*Take-home per month here reflects income tax only; National Insurance and any student loan or pension are separate.
Why you might have the D0 code
- It is typically used for a second job or pension when your main income already fills the basic-rate band.
- You are a higher-rate taxpayer whose other earnings use up the lower bands.
- HMRC expects this source to be taxed entirely at the higher rate on top of your main income.
How to fix a wrong code
If your total income does not reach the higher-rate band, D0 may be collecting too much. Contact HMRC to review how your income is split across your jobs.

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.
