Your gross annual salary represents your employment income subject to tax.
  • All numbers in this calculator are computed on an annual basis.
  • The rates used to calculate income tax and National Insurance are applicable for the current tax year. Refer to the guide for the latest income tax and NIC rates.
  • Income tax is calculated exclusively for UK-based taxpayers. The rates differ for residents of Scotland because Scottish income tax rates differ from those in the rest of the UK and are not accounted for in these calculations.
  • Income tax is calculated based on the standard personal allowance of £12,570.
  • This calculator will not be accurate if the total salary entered falls below £12,750 per year or above £100,000. 
  • National Insurance is calculated considering the taxpayer is in Category letter A. If you are under 21, an apprentice under 25 or over the state pension age,  the NI calculations might be different from what you actually pay in National Insurance.
  • Self-employed expenses solely represent allowable expenses as stated by HMRC. Learn more about what expenses qualify as allowable.
