Japan Consumption Tax (消費税) Calculator

The Japan Consumption Tax (消費税, shohizei) calculator helps businesses and consumers compute the consumption tax on goods and services purchased or sold in Japan. Japan's consumption tax is a value-added tax (VAT) levied at two rates: the standard rate of 10% and the reduced rate of 8% for certain food and beverages and twice-weekly subscription newspapers. The standard 10% applies to most goods and services, restaurant meals (eating-out), alcohol, and tobacco. The reduced 8% applies to food and non-alcoholic beverages for home consumption, and subscription newspapers published at least twice per week. The total consumption tax collected is split between the national consumption tax (国税) and the local consumption tax (地方消費税): at 10%, the breakdown is 7.8% national and 2.2% local; at 8%, it is 6.24% national and 1.76% local. Businesses registered for consumption tax collect output tax on sales and offset it with input tax paid on purchases, remitting only the net difference to the National Tax Agency. The key threshold for registration is ¥10 million of taxable sales in the base period (2 years prior). From October 2023, Japan introduced the Qualified Invoice System (適格請求書等保存方式, Tekikaku Seikyusho Hozonhoshiki) — commonly called the invoice system or インボイス制度 — which requires suppliers to be registered and issue qualified invoices for buyers to claim input tax credits. This fundamentally changed the ability of unregistered small businesses and freelancers to work with registered corporate clients.

Calkulon makes complex calculations simple — built for students and everyday problem-solvers.

1. 1Determine whether the supply is standard-rated (10%) or reduced-rated (8%) based on the nature of goods or services.
2. 2For outward sales: multiply net price by 1.10 or 1.08 to get the tax-inclusive price to charge the customer.
3. 3For purchases: retain qualified invoices (適格請求書) from registered suppliers to claim input tax credits.
4. 4Calculate output tax: total sales × applicable rate.
5. 5Calculate input tax: total purchase amounts × applicable rate — only from qualified invoice issuers.
6. 6Net consumption tax payable = output tax - input tax.
7. 7File and pay quarterly (bi-monthly for small businesses) via e-Tax or paper filing.

• !Applying the standard 10% rate to all food — grocery food for home consumption is 8%.
• !Assuming that unregistered suppliers' invoices still generate input tax credits from October 2023 — they do not under the full invoice system.
• !Displaying prices excluding tax to consumers after 2021 — all consumer prices must be tax-inclusive.
• !Using gross (tax-inclusive) revenue as the base for output tax — output tax is 10/110 of the tax-inclusive amount, not 10% of it.
• !Not registering for the invoice system when corporate clients require it — losing clients is often worse than the compliance cost of registering.
