Essential Tax Support for Foreign Startups in Japan＃３

Tax Registrations & Filing of Tax Treaty Notifications

After incorporating a company, it is mandatory to submit various notifications to the Tax Office, Prefectural Government, and Municipal Office. We ensure all these critical filings are completed accurately and on time.

Post-Incorporation Tax Notifications

• Establishment of Salary-Paying Office & Application for Special Provisions on Withholding Tax: This allows small businesses to pay withheld income tax twice a year instead of monthly, significantly reducing administrative workload.
• Consumption Tax (JCT) Election & Invoice System Registration: We advise on whether to voluntarily become a taxable entity to claim tax refunds and handle the "Qualified Invoice Issuer" registration, which is now essential for B2B transactions in Japan.
• Tax Treaty Notifications for Tax Exemptions or Reductions: Specialized filings to apply for benefits under international tax treaties.

Why these filings matter:

• Avoidance of Double Taxation: Without Tax Treaty notifications, you may be overtaxed on dividends, interest, or royalties. We ensure you benefit from reduced tax rates or full exemptions based on your home country's agreement with Japan.
• Cash Flow Management: Applying for the "Special Provision for Withholding Tax" simplifies your monthly operations, while strategic "Consumption Tax Election" can lead to significant tax refunds if you have high initial setup costs.
• Business Credibility: Registering for the Invoice System is often a prerequisite for doing business with Japanese corporations. Without it, your clients may be unable to claim tax credits, making your services less competitive.
• Legal Compliance: Filing the commencement of business with local and national authorities is the first step to maintaining a "clean" record, which is vital for future visa renewals and bank loan applications.
