  • When a foreign owner should consult a specialist

01First, understand the "residency classification"

In Japan's income tax, the scope of income taxed changes depending on whether the person is a 'resident' or a 'non-resident'. It is judged by whether you have an address in Japan, whether you have lived there for a year or more, and so on.

ClassificationScope of income taxed
Resident (other than non-permanent)All income, domestic and overseas
Non-permanent residentDomestic-source income plus income remitted from abroad, etc.
Non-residentIn principle, only income arising in Japan
Caution
The residency classification is judged by the actual facts of life (address, length of stay, etc.), not by the type of visa. If you have ties to both your home country and Japan, careful judgment including tax treaties is needed.

02The main taxes on a company

If you set up a company (corporation) in Japan and run a business, mainly the following taxes apply.

  • Corporate tax: a national tax on the company's profit (income)
  • Corporate inhabitant tax: a local tax paid to prefectures and municipalities
  • Corporate enterprise tax: a local tax levied on corporations that carry on business
  • Consumption tax: paid when taxable sales exceed a set amount
Key point
A sole proprietorship and a corporation differ greatly in both the tax mechanics and the procedures. Which is advantageous changes with the scale of the business and your future plans. It's best to consult a tax accountant and firm up your approach before incorporating.

03The basics of consumption tax and invoices

Consumption tax is a tax on the provision of goods and services. In principle, an obligation to pay arises once taxable sales exceed a set amount. To issue qualified invoices to counterparties, you must become a registered business.

If you import/export or deal with overseas customers, the treatment of consumption tax becomes more complex still.

04When to consult a specialist

Foreign owners tend to trip over tax in the following situations. Consulting a specialist early helps you avoid trouble.

  1. When setting up a company (sole proprietor or corporation; the consumption-tax choice)
  2. When hiring employees (withholding, social insurance)
  3. When you have income in both your home country and Japan (double taxation, tax treaties)
  4. At closing and filing time

Summary

Understanding the 'resident/non-resident distinction' first is the starting point of Japanese tax.

A corporation faces several taxes — corporate, inhabitant, enterprise and consumption tax.

At incorporation, hiring and cross-border transactions, consult a specialist early to prevent trouble. We support you in five languages.
