A Japan branch is not a separate legal entity from its overseas head office. However, where the branch conducts ordinary business activities in Japan, it will generally constitute a permanent establishment, or PE.
This means that the foreign company will usually need to file Japanese corporate tax returns for the income attributable to its Japan branch.
Is a Japan branch always a PE?
A branch, office or other fixed place through which a foreign company conducts business in Japan may constitute a PE.
A registered Japan branch carrying out activities such as providing services, selling products or managing Japanese customers will generally be treated as a PE.
However, the actual activities of the Japan operation and the applicable tax treaty should also be reviewed. A location used only for limited preparatory or auxiliary activities may be treated differently.
What income is taxed in Japan?
Japan generally taxes the income attributable to the Japan PE.
For tax purposes, the Japan branch is treated as though it were a separate and independent business from its overseas head office. The calculation may therefore include:
- revenue and expenses directly recorded by the Japan branch;
- expenses paid by the head office on behalf of the branch;
- head-office costs reasonably allocated to Japan; and
- transactions or dealings between the head office and the Japan branch.
The appropriate treatment depends on the functions performed, assets used and risks assumed by the Japan operation.
Are separate financial statements required?
The foreign company must be able to identify the assets, liabilities, revenue and expenses attributable to its Japan branch.
In practice, this normally means preparing a branch-level trial balance, balance sheet and profit and loss statement for Japanese tax filing purposes.
The company's global consolidated financial statements alone are generally not sufficient because they do not separately show the financial results of the Japan branch.
Must the branch use Japanese GAAP?
A complete conversion of all accounting records to Japanese GAAP is not necessarily required.
A small Japan branch may record its transactions:
- in a Japanese accounting system;
- directly in the overseas head office's accounting system; or
- through a combination of local records and head-office reporting.
Where the branch's accounting data is maintained under the head office's chart of accounts or group accounting policies, the Japan-related data must be identified, reconciled and adjusted as necessary for Japanese tax filing.
The key requirement is not necessarily a full Japanese GAAP conversion. It is the ability to prepare reliable branch-level financial information and calculate taxable income in accordance with Japanese tax law.
Establishing the process early
Even a small Japan branch should establish a clear process for:
- recording Japan-related transactions;
- collecting invoices and supporting documents;
- identifying expenses paid by the head office;
- reconciling balances between Japan and the head office; and
- preparing branch-level financial information.
Setting up this process from the beginning reduces year-end adjustments and helps both the Japan operation and the overseas finance team understand the branch's financial position.
