What does the tax code OT mean?

The tax code OT means that you have no tax free personal allowance. Not having any tax free personal allowance can result in you paying too much income tax because you don’t have a correct tax code.

To change or check your OT tax code call HMRC.

Why do I have the tax code OT?

The main causes of being given the OT tax code are:

  • You’ve started a new job and you can’t give your new employer your last P45 and didn’t complete a P46
  • Your tax free personal allowance has been used up
  • You have started a new employer and couldn’t give them all the information they need to give you a tax code

How much income tax do I pay with an OT tax code?

The amount of income tax you will pay with the OT tax code is the same as if you had the emergency tax code of BR. The percentage you will pay depends on how much you earn.

  • Normally you will pay 20% income tax on all of your taxable earnings
  • If you are a higher rate tax payer this will increase to 40%, and higher in some cases

Am I due an OT tax code tax rebate?

If you have had an OT tax code its possible you will overpay income tax and be due a tax rebate. A tax rebate can be claimed back for the last four tax years, so if you have had an OT tax code incorrectly in the past, you could be owed a backdated tax rebate.
