Explanatory notes

  • The rate of Corporation Tax on company profits rose significantly in April 2023.
  • Make sure you read our guide to the April 2023 Corporation Tax hike. This change resulted in a significant tax increase for many limited companies.
  • To keep the calculations as simple as possible, we have excluded the Employment Allowance from the spreadsheet. Most small limited companies are ineligible to claim the EA. You must also incur Employers’ NI on salaries in order to claim the EA; most owner-directors tend to draw down minimal salaries.
  • To find out the most tax-efficient salary to pay company directors this tax year, read this salary guide.
  • The income tax rates used apply to England and Wales (not Scotland).
  • Although the calculator has been rigorously tested, please ask your accountant if you have any questions specific to your own business.
