Self Employment Tax Calculator
If you are self employed, use this simplified Self Employed Tax Calculator to work out your tax and National Insurance liability. The calculator uses tax information from the tax year 2017 / 2018 to show you take-home pay. More information about the calculations performed is available on the details page.
What does this mean?
The calculator needs some information from you before working out your tax and National Insurance. Firstly, enter your annual income and outgoings from self-employment. Your tax code, age, and other options might also affect your calculations.
If you are self-employed you will have to tell HMRC about your self-employment income, so that your tax, National Insurance and student loan repayments (if applicable) can be calculated. Using the details provided above, the calculator will try to work out the amount that HMRC will ask you to pay.
If your self-employment income is below the small earnings limit (£6,025 for 2017 / 18) you can apply to HMRC to defer your Class 2 National Insurance contributions - tick this option if this applies to you. You might choose to pay these contributions anyway, to make sure that you are entitled to the benefits of National Insurance, such as the State Pension.
