Enter business profit after the expenses or allowance treatment supported by the tool. Sole-trader profit is assessed through Self Assessment and has different National Insurance rules from employment pay.
Trading allowance and actual expense deductions are alternatives for the same income. Scottish Income Tax, losses, other income, payments on account and Class 1/Class 4 interaction can need a fuller calculation.
