Sole trader or limited company?
A free calculator that shows how much tax and National Insurance you would pay on the same profit either way. Leave your email to open it.
What you will see
Enter your profit and compare the total tax and National Insurance as a sole trader or partnership against a limited company paying a salary plus dividends.
You get charts showing where the break-even point lies, how much you would take home either way, and a line-by-line breakdown for your own figures. It works for one owner or two.
Please remember
It is an indicative model for England, Wales and Northern Ireland, not advice for your own situation. It leaves out things such as Scottish tax bands, student loans, pension contributions, IR35 and the director's loan account.
Tax is only part of the decision. Limited liability, how clients and lenders see you, privacy and admin all matter too, which is why a short conversation is worth having.
