Field notes
Its calculation path moves from gross receipts and expenses to taxable base, progressive rate, credits, prepaid income tax, then a separate local-tax estimate. The form supports freelancer 3.3% withholding and manual entries for other prepayments, while the guidance distinguishes expense-rate estimates from documented actual costs. It explicitly excludes standard-expense-rate cases, health-insurance and pension-premium calculations, and combining employment or other income; local tax is simplified to 10%.
