What Is Japanese Corporate Tax?
Japanese corporate tax is a national tax imposed on the profits of companies operating in Japan.
If a company earns income in Japan, it is generally required to calculate its profits and pay corporate tax to the Japanese tax authorities.
Which Companies Must Pay Corporate Tax in Japan?
A company may be subject to Japanese corporate tax if it is:
- Incorporated in Japan
- Operating a business in Japan
- Earning income through a permanent establishment in Japan
Both Japanese companies and foreign-owned companies can be required to pay Japanese corporate tax.
How Japanese Corporate Tax Works (Simple Version)
In simple terms, the process is as follows:
- The company earns revenue
- Business expenses are deducted
- Accounting profit is calculated
- Tax adjustments are applied
- Taxable income is determined

Japanese corporate tax is based on taxable income, not just accounting profit.
