Understanding Japan's Business Tax Structure

Japan does not have a single "business tax." Instead, foreign entrepreneurs face a layered stack of national and local taxes that interact with each other. Here is an overview of the main categories:

Understanding which taxes apply to your specific business structure is the first step toward effective tax planning. For a broader look at taxes in Japan, check out our Complete Guide to Taxes in Japan for Foreigners.

Corporate Income Tax Rates in Japan

For businesses incorporated in Japan—whether as a kabushiki kaisha (KK) or godo kaisha (GK)—the national corporate tax rate is 23.2% of taxable income. However, small and medium-sized enterprises (SMEs) benefit from a preferential rate structure.

SME Tax Rate Benefits:

• 15% reduced rate applies to the first ¥8 million of annual taxable income for companies with paid-in capital of ¥100 million or less (extended through fiscal year 2027)
• Income exceeding ¥8 million is taxed at the standard 23.2% rate

Effective Combined Tax Rates (National + Local):

Starting from fiscal years beginning on or after April 1, 2026, a new 4% defense surtax will be imposed on corporate income tax amounts. For calendar-year corporations, this takes effect from January 1, 2027.

Local add-ons include prefectural and municipal corporate inhabitant taxes, as well as the enterprise tax (ranging from 3.5% to 7% depending on income bracket and location). In Tokyo, for example, the combined effective rate for a mid-sized SME on income over ¥8 million is approximately 33–34%.

Consumption Tax (JCT): Japan's VAT System

Japan's Consumption Tax (JCT) functions similarly to VAT systems used in Europe. The current rates are:

• Standard rate: 10% — applies to most goods and services
• Reduced rate: 8% — applies to food and beverages (excluding alcohol and restaurant dining), and subscription newspapers

Consumption Tax Registration Thresholds:

A key relief for new businesses is the exemption threshold. Businesses whose taxable base-period sales are ¥10 million or less are generally exempt from collecting and remitting consumption tax. The "base period" typically refers to the fiscal year two years prior.

However, there are important exceptions:

• If a newly established company has capital of ¥10 million or more, it must register for JCT from the first year
• If you voluntarily register, you gain the right to claim input tax credits on business purchases

The Qualified Invoice System (October 2023 onwards):

Since October 1, 2023, Japan implemented the Qualified Invoice System (適格請求書等保存方式, also called the Invoice System or インボイス制度). Under this system:

• Only Qualified Invoice Issuers (登録事業者) can issue tax-compliant invoices
• Businesses that want to claim input tax credits on purchases must have invoices from registered issuers
• Even small sole proprietors who were previously exempt may need to register if their clients require qualified invoices

If your clients are other businesses (B2B), you should seriously consider registering under the Qualified Invoice System, even if your revenue is below the ¥10 million exemption threshold.

Taxes for Sole Proprietors (個人事業主)

If you operate as a sole proprietor (kojin jigyo nushi) rather than incorporating, your business income is treated as personal income and taxed accordingly.

National Individual Income Tax Rates:

In addition, you pay a 10% local inhabitant tax on the prior year's income.

Blue Return (青色申告) — A Must for Sole Proprietors:

The Blue Return (Ao-iro Shinkoku) system offers significant tax advantages for sole proprietors who maintain proper bookkeeping records:

• ¥650,000 special deduction if you use double-entry bookkeeping and file electronically
• ¥550,000 deduction if you use double-entry bookkeeping but file on paper
• ¥100,000 deduction if using simplified bookkeeping
• Ability to carry forward net operating losses up to 3 years
• Deduction of salary paid to family members as business expenses (with proper registration)

To file Blue Return, submit an application to your local tax office within 2 months of starting your business (or by March 15 for existing businesses before the fiscal year begins).

Key Tax Filing Deadlines for Businesses

Missing tax deadlines in Japan can result in late filing penalties and interest charges. Here are the essential dates to track:

Electronic Filing Requirements:

Large corporations with capital exceeding ¥100 million must file corporate tax returns electronically. Smaller businesses can still file by paper, though e-filing is increasingly encouraged.

Withholding Tax on Payments to Non-Residents

If your business makes payments to non-residents or foreign corporations—such as royalties, dividends, interest, or consulting fees—Japan imposes withholding tax at the source.

Standard withholding tax rates:

• Dividends: 20.42%
• Interest: 20.42%
• Royalties: 20.42%
• Business service fees (certain types): 20.42%

Tax Treaty Reductions:

Japan has tax treaties with over 80 countries, which can significantly reduce these withholding rates:

• The US-Japan treaty reduces dividend withholding to 5–10%
• The UK-Japan treaty reduces royalty withholding to 0%
• Many treaties reduce rates to 5–15% for various payment types

Important: You must file the appropriate treaty exemption application (Application Form for Income Tax Convention) at the relevant tax office before making the payment. Filing after the fact may not be accepted.

Deductible Business Expenses in Japan

One of the most effective ways to reduce your corporate or business tax burden is understanding what expenses are deductible. In Japan, ordinary and necessary business expenses are generally deductible, including:

• Office rent and utilities — including home office if it qualifies
• Employee salaries and benefits — including social insurance contributions
• Business travel and transportation — trains, taxis, flights for business trips
• Professional services — accounting, legal, tax advisory fees
• Advertising and marketing — promotional costs, website expenses
• Depreciation — on equipment, vehicles, computers, and other assets
• Entertainment expenses — partially deductible (50% limit for corporations; fully deductible if directly tied to business for sole proprietors)
• Insurance premiums — business-related insurance

Non-Deductible Items:

• Penalties, fines, and interest on tax late payments
• Personal expenses incorrectly claimed as business
• Donations (except approved charitable donations)
• Excessive entertainment costs beyond the 50% limit for corporations
