1. Corporate Income Tax (CIT)

Japan’s Corporate Income Tax (CIT) is applied to both domestic and foreign entities operating within the country. Corporate tax rates in Japan are progressive, and the system includes various deductions and incentives to help reduce taxable income.

Key Corporate Income Tax Rates:

• The standard CIT rate is 23.2%.
• Small and medium-sized enterprises (SMEs) with taxable income under ¥8 million benefit from a reduced CIT rate of 15% on the first ¥8 million of taxable income.

Key CIT Compliance Factors:

• Resident Corporations: Domestic companies, or those whose management and control are in Japan, are taxed on their worldwide income.
• Non-Resident Corporations: Foreign corporations operating in Japan are taxed only on income generated within the country. Non-resident companies that have a Permanent Establishment (PE) in Japan are subject to tax on income derived from their PE.

Tax Deductions and Incentives:

• Research and Development (R&D): Japan offers generous tax incentives for businesses investing in R&D activities, including the possibility of a tax credit of up to 30% of qualifying R&D expenditures.

• Businesses are required to file consumption tax returns on a quarterly or annual basis, depending on the level of their taxable sales.

4. Withholding Tax

Japan’s Withholding Tax system applies to various payments made to non-residents, including interest, royalties, and service fees. Withholding tax rates depend on the type of income and may be reduced if the payer and recipient are covered by a tax treaty.

Common Withholding Tax Rates:

Tax Treaties: Japan has an extensive network of Double Taxation Agreements (DTAs) with over 70 countries, allowing for reduced withholding tax rates or exemptions.
