Japanese Consumption Tax Calculator
＋More features: total of multiple items, and withholding tax
Total of multiple items (mixing 10% and 8% is fine)
Enter the tax-excluded amounts line by line. The tax is charged once on the subtotal for each rate — the usual method on Japanese invoices and receipts.
Withholding tax (freelance invoices in Japan)
Calculates the Japanese withholding tax deducted from fees paid to individuals — writing, lecture, design fees and so on (10.21%, and 20.42% on the portion over 1,000,000 yen) — together with the take-home amount.
Enter an amount and instantly see the tax-included and tax-excluded prices under Japan's consumption tax. It supports both the standard 10% rate and the reduced 8% rate that applies to food and drink. Handy for checking prices while shopping in Japan or preparing an invoice.
How to use
- Enter the amount in yen as a whole number.
- Choose the direction: “tax-excluded → tax-included” or “tax-included → tax-excluded”.
- Pick the tax rate (10% or 8%) and the result appears immediately with the tax breakdown — no button needed.
How it is calculated
- Tax-excluded → tax-included: tax amount = tax-excluded price × tax rate; tax-included price = tax-excluded price + tax amount
- Tax-included → tax-excluded: tax-excluded price = tax-included price ÷ (1 + tax rate); tax amount = tax-included price − tax-excluded price
- The rates are Japan's standard consumption tax rate of 10% and the reduced rate of 8% (food and drink excluding alcohol and eating out, plus newspapers published at least twice a week under subscription), in force since October 1, 2019.
- Examples: 1,980 yen excl. tax (reduced 8%) → tax 158 yen, 2,138 yen incl. tax / 1,980 yen incl. tax (10%) → 1,800 yen excl. tax, tax 180 yen

Assumptions and notes
- Whether the reduced 8% rate applies is decided in detail by item and how it is served (for example, takeout food is 8% while eating in is 10%). Check the National Tax Agency materials for the exact classification.

Frequently asked questions
What does the reduced 8% rate apply to?
Food and drink (excluding alcohol and eating out) and newspapers published at least twice a week under a subscription. The same item can be 8% as takeout but 10% when eaten in the shop.
My result differs from the receipt by 1 yen.
Rounding of fractions below 1 yen (down, up or to the nearest yen) differs by business. This tool consistently rounds to the nearest yen.
What do 内税 (uchizei) and 外税 (sotozei) on Japanese price tags mean?
内税 means the displayed price already includes the tax; 外税 means the price is shown without tax and the tax is added at the register. For consumer prices in Japan, showing the total tax-included price is the general rule.
