For tax-inclusive prices, the tax portion is separated from the total using total ÷ (1 + rate). Qualified invoices usually show separate totals for each tax rate.

Enter each invoice line
Add the line amount and quantity. Use the amount before tax when the quote is tax exclusive, or the charged amount when it is tax inclusive.
Choose the tax rate
Use 10% for standard consumption tax and 8% for eligible reduced-rate items. Use 0% only for non-taxable or out-of-scope lines, or choose a custom rate for special checks.
Select the price type
Tax-exclusive mode adds tax to the line. Tax-inclusive mode backs the tax out of the line total.
Read totals by rate
The result groups taxable subtotal, tax amount, and tax-included total by rate, then shows the invoice grand total.
