What it does
Fields for qualified-invoice items
Issuer name and registration number, transaction date, totals and tax per rate, the rate of each total, and the recipient. Reduced-rate lines are marked ※ with a note.
Tax rounded once per rate
Tax is worked out on each rate’s total, not on each line, and rounded once: down, to nearest, or up. Tax-inclusive entry uses 10/110 and 8/108.
Withholding
For fees under Income Tax Act article 204: 10.21% up to ¥1,000,000 and 20.42% above it, on the tax-exclusive amount, rounded down to the yen.
