Many entrepreneurs establish companies in Singapore, Hong Kong, Dubai, or other low-tax jurisdictions to expand their businesses internationally. However, simply setting up an overseas subsidiary does not necessarily reduce Japanese taxes.
Under Japan’s Controlled Foreign Company (CFC) rules, part or even all of a foreign subsidiary’s profits may still become taxable in Japan if certain conditions are met.
This article explains when Japan’s CFC rules apply and how they affect overseas subsidiaries.
1. What Are Japan’s CFC Rules?
Japan’s Controlled Foreign Company (CFC) rules are anti-tax avoidance rules designed to prevent Japanese taxpayers from shifting profits to companies located in low-tax jurisdictions.
If a foreign subsidiary satisfies certain conditions, Japan may tax part or all of its profits even if those profits have not been distributed as dividends.
The rules generally apply to companies located in jurisdictions with low effective tax rates and whose business activities lack sufficient economic substance.
2. Who Is Subject to the CFC Rules?
The CFC rules may apply when a Japanese individual or Japanese corporation owns or controls a foreign company.
Whether the rules apply depends on several factors, including:
- The foreign company’s effective tax rate
- The nature of its business activities
- Whether it has genuine business operations
- Whether it satisfies Japan’s economic activity tests
3. Four Economic Activity Tests
To determine whether favorable treatment is available, the foreign subsidiary must satisfy several economic activity tests.
(1) Business Test
The subsidiary must conduct an active business.
Companies whose primary activities consist of holding shares, managing intellectual property, or earning passive investment income generally do not satisfy this requirement.
The purpose of this test is to distinguish genuine operating businesses from companies established mainly for tax purposes.
(2) Substance Test
The subsidiary must have a real business presence in the foreign country.
Examples include:
- An office
- A retail store
- A factory
- Employees
- Business equipment
A company that merely rents a mailbox or has only a registered address is unlikely to satisfy this test.
(3) Management and Control Test
The business must actually be managed and controlled in the foreign country.
Important business decisions should be made locally, and the subsidiary should conduct its own operations rather than simply following instructions from Japan.
Companies that exist only on paper generally fail this requirement.
(4) Unrelated Party or Local Business Test
Depending on the type of business, one of the following requirements must generally be satisfied.
For financial institutions, wholesalers, and certain other industries, the company should primarily conduct business with unrelated parties.
For other businesses, the company should mainly conduct its business within the country where it is established.
4. How Is Income Taxed?
The taxation differs depending on whether the economic activity tests are satisfied.
(1) All Four Tests Are Satisfied
If the foreign company’s effective tax rate is below 20%, only certain passive income may be attributed to the Japanese shareholder.
Passive income generally includes:
- Interest
- Dividends
- Royalties
- Certain rental income
- Certain capital gains
However, this passive income is generally excluded if:
- the passive income is less than JPY 20 million, and
- it represents less than 5% of the company’s total income.
(2) Both the Substance Test and the Management and Control Test Are Not Satisfied
If the company fails both the Substance Test and the Management and Control Test, and its effective tax rate is below 27%, the company’s entire income may be attributed to the Japanese shareholder.
(3) One or More Economic Activity Tests Are Not Satisfied
If one or more of the economic activity tests are not satisfied and the effective tax rate is below 20%, all or part of the company’s income may become taxable in Japan, depending on the applicable CFC rules.
5. Practical Examples
Example 1
A Japanese company establishes a manufacturing subsidiary in Vietnam.
The subsidiary has:
- Its own factory
- Local employees
- Local management
- Manufacturing operations
Although Vietnam’s effective tax rate may be relatively low, the subsidiary is likely to satisfy the economic activity tests.
As a result, only limited passive income (if any) may be subject to Japan’s CFC rules.
Example 2
A Japanese resident establishes a company in a low-tax jurisdiction solely to hold investments.
The company has:
- No employees
- No office
- No business activities
- Only investment income
Because the company lacks economic substance, the entire income may become taxable in Japan under the CFC rules.
6. Frequently Asked Questions
Do Japan’s CFC rules apply to individuals?
Yes. They may apply to Japanese tax residents who own or control foreign companies.
What is passive income?
Passive income generally includes interest, dividends, royalties, rental income, and certain capital gains.
Does every overseas subsidiary become taxable in Japan?
No.
Many overseas subsidiaries engaged in genuine business activities satisfy the economic activity tests and therefore are subject only to limited CFC taxation—or none at all.
Which countries are considered low-tax jurisdictions?
Japan’s CFC rules are based primarily on the foreign company’s effective tax rate, rather than a fixed list of countries.
Why is professional advice important?
Japan’s CFC rules are highly technical, and determining whether they apply requires analyzing the ownership structure, effective tax rate, business activities, and local operations of the foreign subsidiary.
