Japan Consumption Tax Calculator
Enter a price, choose the applicable tax rate, and say whether the amount already includes tax. The calculator separates the tax-exclusive amount, consumption tax, and tax-inclusive total in yen.
General price estimate only; this is not the tourist tax-free refund calculator. The correct rate, invoice treatment, per-transaction rounding, and filing treatment depend on the goods, service, and seller's accounting method.

How this estimate works
- For a tax-exclusive price, the calculator multiplies the amount by the selected rate and adds that tax to show the tax-inclusive total.
- For a tax-inclusive price, it divides the amount by 1 plus the selected rate, then subtracts the estimated tax-exclusive amount to extract the tax.
- The standard rate is 10%. The reduced 8% rate covers qualifying food, beverages other than alcohol, and certain subscribed newspapers; restaurant meals and catering generally do not qualify.

Frequently asked questions
How do I extract 10% Japan consumption tax from a tax-inclusive price?
Divide the tax-inclusive price by 1.10 to estimate the tax-exclusive price, then subtract that amount from the total to obtain the tax component.
When should I select the reduced 8% rate?
Use 8% only for a qualifying reduced-rate supply, such as eligible food and non-alcoholic beverages or certain subscribed newspapers. Restaurant meals, alcohol, and most other supplies use 10%.
