Registration is a milestone, not the end of setup
A completed commercial registration is not the end of launching a business in Japan. Depending on the activity, the new company may need tax notifications, payroll administration, social insurance arrangements, employment procedures, licences and banking steps.
JETRO provides a useful list of common notifications. The actual list and deadlines depend on the company’s facts and the offices involved.
National tax notifications
JETRO states that a newly incorporated subsidiary generally files a notification of incorporation within two months of incorporation. A salary-paying office notification generally has a one-month deadline from establishment of that office.
A corporation seeking approval to file blue-form returns must pay attention to the special timing: JETRO states a deadline of the day before the earlier of three months from incorporation or the last day of the first business year. A tax accountant should assess whether and when the filing is appropriate.
Local tax office notifications
Prefectures and municipalities have their own incorporation/office notifications. The specific form and deadline depend on local rules. Do not assume a national tax-office filing also completes all local tax procedures.
Staffing and social insurance
If the business will employ people, labour, employment-insurance and social-insurance notifications may become necessary. JETRO lists different deadlines for different events; a qualified labour and social-security consultant can help establish the applicable plan.
The presence of a representative director can also be relevant to social insurance coverage. Seek a practitioner’s advice based on the company’s actual operations and remuneration.
Other operational requirements
- Corporate bank account application and related evidence.
- Business permits, if the planned activity requires permission.
- Invoices, bookkeeping system and treatment of consumption tax.
- Employment contracts, payroll arrangements and source withholding.
- Contracts, company website and formal contact information for suppliers.
Who coordinates the whole sequence?
Tax accountants, labour and social-security attorneys, registration practitioners and other professionals each handle different regulated tasks. KIZUNA’s role is to help the international client keep an agreed action list, arrange ordinary language support and coordinate progress between the parties.
