Japan Corporate Tax Calculator

Summary

Enter your taxable income and company size to calculate Japan corporate tax — national rate, local corporate tax, and effective combined rate.

How it works

1. Enter your company's taxable income in Japanese Yen (JPY).
2. Select your company type — Standard Company or SME (paid-in capital ¥100M or less).
3. The calculator applies the national corporate tax: 15% on the first ¥8M for SMEs, 23.2% on the remainder (or all income for standard companies).
4. Local corporate tax is added at 10.3% of the national tax amount.
5. Total tax payable, after-tax income, and effective combined rate are displayed instantly.

Use cases
