How does this work?
We calculate your taxable profit (income minus allowable expenses), then work out the Income Tax and Class 4 National Insurance due. The result is shown as a simple percentage you should set aside from every invoice. If you're also employed on PAYE, we take your employed income into account to calculate the correct marginal tax rate on your self-employed profit.
The UK pay calculator that just gives you the answers.
