1. Structure of Withholding Tax Regulations in Japan
Japan’s withholding tax system is primarily stipulated under the Income Tax Act. Its purpose is to collect taxes directly at the source of income, ensuring timely payment to the tax authorities. For foreign corporations, a key point is that the obligation is linked to Japan-source income. The framework can be summarized as follows:
① By type of income – Categories of Japan-source income
The types of income subject to withholding are specifically listed, which are mainly included as Japan source income under Article 161 of the Income Tax Act. Common examples include:
- Interest income: Interest from deposits and bonds handled domestically. Example: Interest on deposits from domestic financial institutions.
- Dividend income: Dividends and profit distributions received from domestic corporations.
- Salary and retirement benefits: Compensation and retirement allowances corresponding to work performed in Japan.
- Royalty: Compensation related to the use of patent rights, copyrights, etc.
- Income from the provision of personal services: remuneration for performances, lectures, and specialized services within the country.
-
Real Estate income: Consideration for the lease and transfer of domestic real estate, etc.
(Note: There may be reductions or exemptions due to tax treaties. Procedures such as notifications are required for the application of the treaty.)
② By recipient category – Resident, domestic corporation, Non-resident and foreign corporation
The scope of withholding differs depending on the recipient’s status:
- Resident individual / Domestic corporation: Japanese residents and corporations
- Non-resident individual / Foreign corporation: Entities without domicile or head office in Japan; the scope of taxable Japan-source income is generally broader. For non-resident individuals and foreign corporations, the default domestic withholding tax rate is 20.42% (including the special reconstruction income tax), with certain exceptions (e.g., 15.315%). Tax treaties may further reduce or exempt these rates.
③ By payer – The withholding tax agent
The obligation lies with the payer who makes a payment of Japan-source income in Japan.
Example: If a foreign corporation, through its Japan branch, pays fees to a consultant residing in Japan, the branch must withhold the applicable tax and remit it by the 10th of the following month.
Even if the payment is processed abroad, it may be treated as a domestic payment if the payer has a permanent establishment (PE) in Japan.
2. Special Rule for Payments Made Abroad
Foreign corporations should pay special attention to the rule under Article 212 of the Income Tax Act:
Even if Japan-source income is paid abroad, if the payer has an address, domicile, office, place of business, or equivalent (such as a PE) in Japan, the payment is deemed to be made domestically, triggering withholding obligations.
Examples of PE:
- Fixed place: physical locations such as branches, factories, and offices.
- Agent PE: The domestic agent in Japan has the authority to conclude contracts, etc.
- Construction PE: Construction projects that exceed a certain period, etc.
Key points:
- No PE: Payments abroad generally do not trigger withholding obligations unless other deemed domestic payment rules apply
- With PE: Deemed domestic payment rules apply, and withholding obligations arise. Domestic rates typically range from 10%–20.42% (exceptions: 15.315%, etc.), with potential treaty reductions or exemptions.
3. Unique Feature of Japan’s System: Independent Liability of Payers and Penalty Risks
In Japan, the obligation to withhold tax is independent of the recipient’s tax filing. If the payer fails to withhold and remit taxes, penalties such as non-payment surcharges and delinquent tax will be imposed, regardless of whether the recipient pays tax.
Practical measures include: Designing payment flows (domestic/overseas) at the contract stage, Preparing and submitting treaty application forms in advance, Keeping evidence for treaty eligibility and payment classification and Managing remittance deadlines (generally the 10th of the following month).
4. Summary – Key Considerations for Foreign Corporations in Japan
When a foreign corporation conducts business in Japan, the obligation for withholding tax is a point that cannot be overlooked.
- Determine obligations based on type of income, recipient status, and payer’s presence in Japan
- Payments abroad may still trigger withholding if the payer has a PE in Japan
- Withholding is the payer’s independent obligation—penalties apply for non-compliance
- Tax treaty relief generally requires advance filing (refund claims may be possible in some cases)
Before making the first payment, foreign corporations should confirm treaty applicability and payment structures with a qualified tax advisor to ensure both compliance and cost efficiency.
