FAQ
Can I enter either tax-exclusive or tax-inclusive amounts?
Yes. Use the switch at the top of the form to choose tax-exclusive input (net) or tax-inclusive input (gross). When you select gross, the calculator reverses the tax so you can see the net amount and tax breakdown.
Does the calculator support reduced tax rates and rounding rules?
You can assign the standard 10% rate, the reduced 8% rate, or any custom rate per item. Rounding supports nearest, up, or down with either whole yen or two decimal places.
