Tax Code Guide
D0
Tax Code D0 (Higher Rate)
What does this code mean?
D0 means all your income from this source is taxed at 40%. This usually happens if you have a main job that pays well above the higher rate threshold (over £50,270), so your second job is fully taxable at the higher rate. If this is your only employment, you are very likely overpaying tax significantly.
Who gets this code?
High earners with a second income source where the main job already uses up the basic rate band.
