A Japan company that pays a director's fee (役員報酬) to a non-resident director withholds Japan income tax on that payment, regardless of where the director physically performs board duties. The obligation exists because director remuneration from a Japan company is sourced to the paying entity under the Income Tax Act (所得税法), not to the location where the work happens. The standard non-resident withholding rate is 20.42%, and most tax treaties leave director's fees outside their relief provisions.
Why Does Japan Tax a Director's Fee Paid to Someone Who Never Enters Japan?#
Director remuneration is treated differently from ordinary employment or consulting income under Japanese tax law. Ordinary service income from a non-resident is generally sourced to where the services are physically performed; a director's fee is sourced to the company paying it, because a director's relationship to a Japan company is a company-law office (役員), not a labor contract. This is the fact pattern that catches foreign-owned KK and GK structures: a parent-company executive is appointed as a formal director of the Japan subsidiary, continues to sit overseas, attends board matters remotely, and never sets foot in Japan in a given fiscal year. The source-of-income analysis does not move. The Japan entity is the payer, the Japan entity is the source, and the fee is Japan-source income the moment the board resolution and payment exist. This sits apart from the related but distinct question of a non-resident advisor or 顧問 paid a consulting fee, where the physical-performance test can apply differently depending on where the advisory work is actually done.
Does a Tax Treaty Reduce or Eliminate the Withholding?#
Sometimes, but director's fees are a common carve-out in OECD-model-based treaties, so the answer depends on the specific treaty Japan has with the director's country of residence, not on a general rule. Many Japan tax treaties follow the OECD Model Tax Convention pattern, under which director's fees paid by a resident company to a non-resident board member remain taxable in the source state (Japan) even where the treaty reduces or eliminates withholding on other categories of income, such as dividends, interest, or ordinary personal services. A company assuming its relevant treaty will exempt the director from Japan withholding, the way it might for royalties or certain service fees, is often wrong on this specific income category. The correct process is to pull the actual treaty text article covering director's fees (articles vary by treaty and some use different numbering conventions) and confirm the Japan-source taxing right it preserves, rather than assuming treaty relief applies by default. Where a reduced rate under a treaty is available for other payment types the same non-resident director receives, filing the relevant 租税条約に関する届出書 (treaty benefit notification) with the payer is the mechanism, separate from the director's-fee question.
What Must the Japan Company Do to Withhold and Remit?#
The Japan company paying the fee is the withholding agent (源泉徴収義務者), responsible for deducting the tax at the time of payment and remitting it to the tax office, not the director. Withholding on non-resident payments is a monthly obligation: the company withholds 20.42% from each payment as it is made and remits the withheld amount to the tax office by a fixed deadline the following month. A company that waits until fiscal year-end, or treats the director's fee as a gross payment with no deduction, has already missed the withholding event; the liability for the uncollected tax, and any associated penalty and interest, sits with the company as the withholding agent, not with the non-resident director. Companies managing a non-resident director's fee alongside other non-resident national-tax filings, such as a 納税管理人 (Tax Agent) appointment, should coordinate the two: see the Japan Tax Agent (納税管理人) guide for how that separate appointment works and why it does not substitute for the withholding obligation itself.
Reimbursing Travel Costs vs Paying a Director's Fee: Where Companies Get This Wrong#
Reimbursing a director's actual, documented business costs is not compensation and carries no withholding; paying any amount styled as a director's fee, however small, is compensation and triggers the 20.42% withholding from the first payment. The distinction turns on substance. A true 実費弁償 (actual-cost reimbursement) for airfare, hotel, or meeting costs incurred on the company's business, supported by receipts, is not the director's income and generates no withholding question at all, in the same way the actual-cost reimbursement pattern works for business expense categories such as entertainment expense (交際費) treatment. A token director's fee, even a nominal monthly amount meant mainly to formalize the appointment rather than to compensate meaningfully, is still compensation in form, and the full 20.42% applies to the gross amount paid, not to some net-of-expenses figure. The common failure mode among foreign-owned KK and GK companies is setting a small director's fee for an overseas parent executive without ever registering a withholding process, on the assumption that a small amount or a remote director does not trigger the same rule as a resident director's salary. It does, and the company, not the director, bears the exposure when a tax office identifies the gap on audit.
A related exposure worth flagging at the same time: if the non-resident director's role shifts from governance into day-to-day management or deal execution physically conducted from Japan, the analysis can intersect with permanent establishment risk for the parent company, which is a separate question from the withholding mechanics above and turns on what the director actually does, not on the director's fee itself.
Three points worth holding together when scoping this:
(a) the source of a director's fee is the paying Japan company, not the location where the director works, so remote non-resident directors remain inside the withholding rule (b) a tax treaty may or may not change the outcome, and director's fees are commonly carved out of treaty relief even where other income categories benefit, so the specific treaty text controls (c) only a payment styled as compensation triggers withholding; a documented reimbursement of the director's actual business costs does not, and conflating the two is the recurring error
Where Aplash's Role Fits#
Aplash's tax and legal consulting work on this fact pattern covers the structuring question (whether to appoint the overseas executive as a formal director versus a no-fee advisory 顧問 relationship, and what the withholding exposure looks like under each) and the withholding-obligation determination itself. Preparing and filing the actual withholding tax return and remittance paperwork with the tax office is work that routes to a partner Licensed Tax Accountant (税理士), consistent with the 税理士 licensing boundary that applies to tax return preparation generally. Aplash sets up the structure and determines what the obligation is; the partner 税理士 handles the periodic filing.
Frequently Asked Questions#
Does it matter that the non-resident director never physically visits Japan?
No, and this is the point most foreign-owned companies get wrong. A director's fee is sourced to the Japan company paying it, not to where the director performs duties, so a director who manages everything remotely from the parent company's home country still generates Japan-source income subject to withholding on the fee.
Can the company just gross up the payment instead of withholding?
The company can agree to bear the tax economically by grossing up the payment so the director receives a target net amount, but the withholding and remittance obligation to the tax office still exists and still falls on the Japan company; grossing up changes who absorbs the cost, not whether withholding happens.
Is a non-resident director the same as a non-resident consultant or 顧問 for tax purposes?
No. A formally appointed company-law director (役員) is taxed under the director's-fee sourcing rule described above regardless of where duties are performed, while a non-resident 顧問 or consultant paid a fee for services is typically analyzed under the separate rules for where those services are physically performed, which can produce a different outcome for the same underlying individual depending on which role they actually hold.
