Using the calculator to estimate your tax bill as a sole trader or a limited company

Our free online limited company tax calculator will help you estimate how much tax you’ll pay on your profits as a sole trader compared to a limited company. Enter your annual profits into the tax calculator to work out if incorporating a limited company might help you to save money (but just remember there might be other reasons why you choose one option over the other!).

The tax calculator should only be used as a guide, and your actual tax bill might be different depending on your circumstances. To give you an idea of what tax as a sole trader looks like in comparison to a limited company, the calculator assumes:

  • Figures are based on a full tax year
  • You are the only employee and director of the company
  • You take a salary up to the National Insurance (NI) Primary threshold of £12,570 (so although the company will pay NI as an employer, it can offset this and the salary cost against your bill for Corporation Tax)
  • You do not have any other income

The profit amount you can enter is limited to £50,000, which is the basic rate tax threshold, so you won’t be able to use it for higher profit amounts. This is because it’s often more tax efficient to form a limited company over this threshold – but not always! It all depends on your situation.

You can discuss this in more detail with your accountant directly, or talk to one of our advisers today by calling 020 3355 4047 or by pressing the Live Chat button.

Should I be a sole trader or set up a limited company?

The calculator will give you a side-by-side overview of which business structure is likely to be more tax efficient, but there might be other points to consider before you make any big decisions!

As well as comparing your take home pay as a sole trader versus setting up a limited company, it’s useful to think about things like risk, the admin involved, protecting personal assets, and privacy. If you’re already trading as a sole trader and you’re thinking of switching, or if you’re not sure whether to incorporate a limited company straight away, there are lots of variables.

We go into it all in more detail in our article about the differences between sole traders and limited companies.
