See breakdownHow this calculator works
Your income minus allowable expenses (or the £1,000 trading allowance) is your taxable profit. Profit gets the same £12,570 personal allowance and income tax bands as an employee’s salary — what changes is National Insurance. Class 2 has been effectively abolished since April 2024 (voluntary contributions remain for protecting your State Pension), and Class 4 is banded: 6% on profits between £12,570 and £50,270, 2% above. You report it all through Self Assessment by 31 January — and if your bill tops £1,000, payments on account split next year’s bill into two advance instalments, due 31 January and 31 July. Every rate is linked to its gov.uk source below.
