OT Tax Code

In the context of the UK tax system, the term “OT tax code” refers to a specific tax code used by Her Majesty’s Revenue and Customs (HMRC) to calculate an individual’s income tax liability.

“OT” tax code is used when the taxpayer is not eligible for any personal allowance. Usually, the individual gets £12570 every year (as of 2023-24) its the maximum allowance you can get in a year. This personal allowance may vary based on individual circumstances.

If you have an OT tax code on your payslip this refers that the entire amount is taxable and you will not get any personal allowance. For example, if you get £24000 in a year as a salary your entire amount is taxable, whereas you should get a personal allowance of £12570 for a year which means (£24000 – £12570) = £11430, you should pay tax only on this tax. OT tax code applied if you have multiple sources of income and you have already consumed your personal allowance for that year. Or you may have started a new job or you haven’t given enough information to your employer.

Tax code applies based on individual circumstances and they can be changed if your situation changes or if the tax code is applied by mistake. If you have any concerns about the tax code you should contact an accountant near you for professional help who can help you to change the tax code and also may help you to get the tax refund if any or you may contact HMRC on tax codes.
