What Does The D0 Tax Code Mean?

A tax code is assigned by the HMRC to anyone who is in a full-time or part-time job and individuals receiving a private pension. It does not apply to individuals who are unemployed, fully self-employed or only receiving a state pension. While this blog post aims to explain the D0 tax code in detail, we will also be maintaining a general discussion of taxes in the UK with a key focus on income tax bands.

What Does The D0 Tax Code Mean?

The D0 tax code means that the individual will be liable to pay income tax at a higher rate of 40 per cent for all their incomes. It is commonly used in cases where individuals have more than one job or pension. The HMRC issues this tax code to individuals if all of their tax-free allowances have been used against another source of income. 

Individuals are assigned a D0 tax code because (a) they have multiple sources of income and (b) calculations predict that their second source of income will cause their total combined gross earnings to be between £37,701 and £150,000. This is only after any tax-free allowance has been deducted.

Tax codes are a combination of letters and numbers that determine the amount of income tax due on an individual. While the letters indicate your financial position and how it relates to your personal allowance, the numbers tell your employer pr pension provider the amount of tax-free income that you are eligible for in that tax year. 

For instance, 1257L (currently the most common 2021-22 tax code in the UK) refers to the new Personal Allowance rate for 2021-22, which is £12,570 and the letter “L” indicates that the individual is entitled to this amount of tax-free income. Any taxes that are to be charged will be above additional amounts beyond this figure.

The following steps are followed by the authorities while assigning tax codes:

  • Step 1: Your tax allowances are calculated. In most cases, this is an individual’s personal allowance added to any other allowances and job expenses.
  • Step 2: Your deductions are calculated. These are incomes for which tax has not been paid and may include any part-time work or certain state benefits.
  • Step 3: The deductions are subtracted from the tax allowances. The result is your pre-tax income. If this amount equals personal allowance, your income remains tax-free.
