When you try to establish a base overseas, three options emerge: a local subsidiary, a branch office, and a liaison office. People tend to start by comparing establishment costs, but what you should decide first is what you will do locally, in whose name contracts will be made, and to what extent the Japanese headquarters will assume business liability. The necessary structure differs between a base for market research only and one that holds inventory and sells to customers.

This paper provides a general overview for Japanese corporations expanding overseas. We assume a subsidiary is a corporation with a separate legal personality from its parent company, where the liability of shareholders is, in principle, limited to the amount of their capital contribution. The corporate form, foreign investment regulations, licenses and permits, and tax treatments vary depending on the destination country. While official documents from Singapore are used as a specific example, their treatment cannot be directly applied to other countries.

Comparing the three forms in terms of contracts and responsibilities

Singapore'sACRA's Guide to Forms of Business PresenceThey also distinguish subsidiaries as separate legal entities, branches as extensions of foreign companies, and liaison offices as temporary bases incapable of revenue-generating activities. It is not enough to simply choose a liaison office just because you are starting small; whether your planned activities fall within the permitted scope is the starting point.

Creating a subsidiary does not eliminate all risks for the parent company.

If the local subsidiary procures goods, sells them to customers, and hires employees, the party to those contracts is basically the subsidiary. In the case of a branch office, the Japanese corporation itself becomes the party to the contracts. Who bears the liability differs in scenarios such as when damages are claimed by a customer, or when cash flow deteriorates due to the inability to collect payments.

However, if the Japanese parent company guarantees the subsidiary's bank borrowings or lease agreements, the parent company will bear responsibility based on those guarantees. Also, obligations directly incurred by the Japanese headquarters itself, such as signing sales contracts, are a different matter. The explanation of the corporate form of limited liability and the actual content of guarantees and contracts to be concluded must be considered separately.

See if a liaison office can be used as a "pre-business base"

For example, if a Japanese manufacturer is at the stage of assigning personnel to research local demand and regulations and conducting interviews with potential customers, a liaison office is a candidate. On the other hand, if the plan is to take orders locally, determine prices, execute sales contracts, and even provide paid maintenance services, it is better not to assume that such operations can be handled by a liaison office.

In principle, the system is designed with a maximum duration of three years in mind, so it is necessary to consider transitioning to a sales base or withdrawing.

It is not a format that any company can freely choose.

Taxation is reviewed by separating legal entity status from actual operations.

For branch taxation, a PE (Permanent Establishment) is important. This is a foundational concept when taxing the business profits of a foreign company, such as a fixed place where business is conducted in that country. A branch that conducts operations typically falls under a PE, and local taxation is considered regarding the profits attributable to that PE. However, the profits recorded in the branch's books do not necessarily become the taxable profits; the division of functions and allocation of expenses with the head office also become issues.

Even with the name and registration of a representative office, that alone does not determine tax exemption. The Japan-Singapore Tax Treaty also determines a Permanent Establishment (PE) based on the place of business and an agent's contracting authority, and provides exclusions for certain information-gathering or preparatory and auxiliary activities. For example, if personnel at a research base repeatedly conclude sales contracts in the name of the head office, a reassessment of the scope of activities and the PE is necessary. To confirmconsolidated provisions published by the Ministry of FinanceThis is helpful, but the legal basis for application is the authentic text of the agreement, etc.

The subsidiary is taxed as an independent legal entity. The mere relationship of a parent and subsidiary does not constitute a PE of the parent company, but depending on the activities performed for the parent company, a separate PE issue may arise. In addition, the prices of goods and service fees between the parent and subsidiary are treated as transactions between separate legal entities,Transfer pricing studyis required.

Taxation in Japan and the methods for remitting funds back are also different.

In principle, the profits and losses of overseas branches of a Japanese corporation are included in the calculation of the Japanese corporation's income. The timing of taxation in Japan is not determined simply by whether the profits are retained locally or remitted to Japan. Regarding corporate taxes and similar taxes incurred locally, a foreign tax credit is considered; however, there are limitations on the scope of eligible taxes and a credit limit, meaning it is not a system where all taxes paid abroad are guaranteed to be refunded in full.

There is a system that excludes 95% of dividend amounts from gross revenue for dividends from a subsidiary to its Japanese parent company, provided that certain requirements regarding the shareholding ratio and holding period are met.Explanation of the double taxation relief method by the Ministry of FinanceIt distinguishes between the foreign tax credit system for branches and the subsidiary dividend system. For dividends, local withholding taxes and tax treaties are also checked.

Also, leaving profits in a subsidiary does not always allow you to defer Japanese taxation. In certain cases,Controlled Foreign Company (CFC) rulesIncome is thus aggregated on the Japanese side. This system verifies shareholding relationships, actual business and management conditions, tax burden ratios, types of income, and other factors, and cannot be determined based solely on the local nominal tax rate.

Even in cash management, you cannot move a subsidiary's deposits in the same way as those of the Japanese head office. You must organize whether the funds are dividends, loan repayments, or transaction payments, and check the necessary resolutions, contracts, and tax implications. While fund transfers between a head office and branches occur within the same legal entity, foreign exchange regulations, remittance procedures, and the existence of additional taxation on branch profits must be checked for each country.

Visualize the scenarios for generating sales and withdrawing beforehand.

For example, if the initial plan is just market research, but six months later you intend to hold local inventory and deliver and bill under a local entity, there is a reason to consider a subsidiary or branch office from the beginning. Conversely, if you are at the stage of investigating the commercialization prospects, you will need to check the scope of activities and establishment conditions for a liaison office. This is an explanatory example and does not indicate a decision to establish an entity in a specific country.

Even when withdrawing, there are differences: for a subsidiary, it involves company liquidation or share sales; for a branch, it involves closing the branch. However, regardless of the form, tasks such as employee contracts, office lease cancellations, debt collection, tax payments, and the completion of registrations remain. You cannot simply lump them all together by saying "a branch can be withdrawn from immediately."

When making a comparison, outline the contractor, the billing party, the inventory owner, the employer, the presence of headquarter guarantees, and the profit return method in accordance with the planned business flow. Then, by checking local regulations against the taxation of both Japan and the local country, the differences that cannot be seen from setup costs alone will become clear.
