How to remove VAT from a price in Japan

Published June 12, 2026 · 2 min read

Why you cannot just subtract 10% from a gross price in Japan, and the correct formula for extracting VAT.

Why subtracting 10% gives the wrong answer

The tax was calculated on the net price, not on the gross price. Taking 10% off the gross price removes too much. The correct approach is to divide the gross price by 1.1, which returns the net price exactly.

Worked example

Here is the calculation with sample figures. Change any number in the Japan Reverse VAT Calculator to run your own.

The tax fraction

If you only need the tax portion, multiply the gross price by 0.0909. That fraction, the rate divided by 100 plus the rate, is sometimes called the tax fraction, and it is useful when you reconcile receipts that only show tax-inclusive totals.

Where this comes up

Expense claims, receipts from shops in Japan, marketplace payouts and quotes given "all in" all need the tax extracted before you can record the net cost correctly in your books.

Quick reference at 10%

Common amounts in Japan, worked both ways: adding tax to a net price, and extracting it from a price that already includes tax.

How Japan compares

Standard rates on file for other countries. A difference of a few points matters most on high-value purchases and on cross-border sales.

Using the calculator step by step

1. Open the Japan Reverse VAT Calculator.
2. Type your figures into the numbered lines. Results update as you type.
3. Check the rate field. It starts at 10%; change it if a reduced rate, local surcharge or exemption applies to you.
4. Read the result on the receipt panel, and use the formula shown under it if you need to explain the figure to a client or colleague.

Key terms

Exempt supply

A sale that falls outside the tax entirely. No tax is charged and input tax usually cannot be reclaimed.

Withholding

Tax deducted at source, by an employer or payer, before the money reaches you.

Reduced rate

A lower rate that applies to specific categories, often essentials such as food, medicine or books.

Deduction

An amount subtracted from taxable income. It saves tax equal to the deduction times your marginal rate.

Gross amount

The amount after tax is added, which is usually what a consumer pays.

Common mistakes to avoid

• Subtracting 10% from the gross price instead of dividing by 1.1.
• Reclaiming tax on receipts that do not show a valid tax breakdown.
• Recording gross amounts as costs and then reclaiming the tax a second time.
