A European company that hires its first employee in the United States rarely treats the decision as a structuring event. The hire is a salesperson or an account manager working from home in Austin or Boston, paid through a payroll provider and reporting to a manager in Amsterdam. No office is leased. No subsidiary is incorporated. The group continues to file one corporate tax return, in its own country, and assumes that is the end of it.
It is often not. Whether a foreign enterprise has a taxable presence in the United States is answered by the convention between the two states, and the convention does not ask about the lease. It asks whether business is carried on through a fixed place, and whether a person acting for the enterprise habitually exercises authority to conclude contracts in its name. A house in Austin can satisfy the first. A salesperson with a commercial mandate satisfies the second.
What the convention means by a fixed place of business
Under Article 5(1) of the convention between the United States and the Netherlands, a permanent establishment is a fixed place of business through which the business of an enterprise is wholly or partly carried on. Article 5(2) adds a list the term includes especially: a place of management, a branch, an office, a factory, a workshop, and a mine, oil or gas well, quarry or other place of extraction of natural resources. Nothing in it requires a lease, a nameplate or a separate legal entity.
Article 5(3) sets a duration test for one category only. A building site or construction or installation project constitutes a permanent establishment only if it lasts more than twelve months. No other paragraph counts months or days, so there is no equivalent grace period for an employee working from a spare bedroom. A home office is analyzed under paragraph 1 and under the exclusions in paragraph 4, not against a clock.
Paragraph 4 is where most home office arrangements are argued. It removes from the definition facilities used solely for storage, display or delivery of the enterprise’s goods, a stock of those goods held solely for storage, display or delivery or solely for processing by another enterprise, a fixed place maintained solely to purchase goods or collect information, one maintained solely for any other activity of a preparatory or auxiliary character, and one maintained solely for a combination of those whose overall result is still preparatory or auxiliary. The word carrying the weight is solely. A researcher gathering market data may fit within it. A person who carries the revenue-generating function of the enterprise in the United States does not.
The dependent agent, and the employee who never signs
Article 5(5) reaches arrangements with no fixed place at all. Where a person other than an agent of independent status is acting on behalf of an enterprise and has, and habitually exercises, in one of the states an authority to conclude contracts in the name of the enterprise, that enterprise is deemed to have a permanent establishment in that state in respect of the activities the person undertakes for it. The rule does not apply where those activities are limited to the ones listed in paragraph 4 which, exercised through a fixed place of business, would not make that fixed place a permanent establishment.
Two words decide most cases. Habitually excludes the isolated transaction and captures the pattern. Authority is the other, and the article says nothing about writing, signature or a power of attorney, so the question is factual rather than documentary. What it does require is an authority to conclude contracts in the name of the enterprise, which is a narrower thing than influence over their terms.
That distinction is the whole of the exercise. This convention retains the older formulation rather than the wider language of Article 12 of the multilateral instrument, which reaches a person who habitually plays the principal role leading to the conclusion of contracts that are routinely concluded without material modification. That article operates only on a covered tax agreement, and the United States appears neither as a signatory nor as a party to the instrument, so it does not reach this convention. The commissionaire arrangements named in the title of that article therefore sit outside the text that governs the group, which runs the other way from what groups usually assume.
Article 5(6) preserves the independent agent. An enterprise is not deemed to have a permanent establishment merely because it does business in a state through a broker, general commission agent or any other agent of independent status, provided those persons act in the ordinary course of their business. Whether they do is a question of fact, not of the label on a contract.
What the exposure costs once it exists
Section 882(a)(1) of the Internal Revenue Code makes a foreign corporation engaged in trade or business within the United States taxable as provided in section 11, 55 or 59A on its taxable income effectively connected with that trade or business. Section 11(b) fixes that rate at 21 per cent of taxable income. Where the convention applies, Article 7 leaves the profits of the enterprise taxable only in its own state except so much of them as is attributable to the permanent establishment.
Then the second layer. Section 884(a) imposes on a foreign corporation a tax of 30 per cent of the dividend equivalent amount, a proxy for branch profits treated as repatriated. Section 884(e) allows an income tax treaty to reduce that charge, but only where the corporation is a qualified resident of the treaty state. Article 11 of the convention permits the additional tax and, in paragraph 3, caps it at the rate specified in Article 10(2)(a), which is 5 per cent. The cross-reference is to that rate alone, not to the shareholding Article 10(2)(a) requires of a dividend recipient. The same paragraph then disapplies the charge for a company engaged before 1 October 1998 in the activities giving rise to the profits attributable to that permanent establishment, or to the income or gains to which Article 6 or Article 14(1) applies, for one that is a qualified person by reason of Article 26(2)(c), for one entitled to benefits with respect to the dividends under Article 26(3), and for one that has received a determination under Article 26(7) with respect to that paragraph. Outside those cases, a Dutch enterprise that is a qualified resident faces 21 per cent and then 5 per cent, rather than 21 per cent and then 30 per cent.
The distance between those outcomes is why limitation on benefits is not a formality. Except as otherwise provided in that article, Article 26 gives a resident the benefits of the convention only if it is a qualified person and meets any other specified conditions, and its paragraphs 3 to 7 open routes for a resident that is not one. The qualified resident test in section 884(e) runs alongside it. The regulation on qualified residence gives a company more than one way through: stock ownership with base erosion, primary and regular trading of its shares, an active trade or business, or a ruling from the Commissioner. A holding company that meets none of them is where the branch profits tax returns at the statutory rate.
The deductions that disappear if no return is filed
Section 882(c)(2) provides that a foreign corporation receives the benefit of the deductions and credits allowed to it only by filing a true and accurate return, in the manner prescribed in subtitle F. Without a return, the charge is computed on gross effectively connected income rather than on profit.
Treasury Regulation section 1.882-4(a)(3)(i) sets the outer limit. Where the corporation filed a return for the immediately preceding year, or the current year is its first, the return must be filed within 18 months of the due date under section 6072 for the deductions and credits to survive. Where no return was filed for the preceding year, the period ends on the earlier of that date and the date the Internal Revenue Service mails a notice that no deductions or credits may be claimed. Paragraph (a)(3)(ii) lets those deadlines be waived where the corporation establishes that it acted reasonably and in good faith, which it cannot do if it knew it had to file and chose not to, and not unless it cooperates in determining the liability. A short list of items, among them the charitable contributions deduction, survives whether or not the return is timely filed.
The practical consequence is that a company discovering a permanent establishment three years after it arose has more at stake than interest on unpaid tax. In one mandate a European group’s United States activity had run for two full years through two remote hires. The exposure that mattered was not the tax on the margin. It was the clock that had already run against the deductions.
Payroll does not wait for the treaty analysis
Employment tax obligations arise from the presence of an employee working in the United States. They do not depend on the permanent establishment analysis, and the social security charge among them sits outside the convention altogether, because the United States taxes it covers are the federal income taxes imposed by the Internal Revenue Code, excluding social security taxes, and two excise taxes. Publication 15 for 2026 sets the social security tax at 6.2 per cent each for employer and employee on wages up to a base limit of 184,500 dollars, and the Medicare tax at 1.45 per cent each with no wage base limit. Employers must also withhold the additional Medicare tax of 0.9 per cent on wages paid to an employee above 200,000 dollars in a calendar year, a charge on the employee alone with no employer share.
Federal income tax withholding, state income tax withholding where the state imposes one, state unemployment insurance and workers compensation cover run alongside. Each requires registration, and each leaves a footprint visible to anyone who looks.
Groups often engage an employer of record to carry these obligations. That solves the payroll registration problem. It does not answer the permanent establishment question, because the employer of record is not the enterprise whose business the employee is carrying on.
Social security has a switch of its own. Article 9 of the social security agreement between the two states keeps a person employed by an employer established in one territory, and sent by that employer to work in the other for a period not expected to exceed five years, subject to the laws of the sending state alone. Paragraph 2 withdraws that only where the posting runs from the United States to the Netherlands and the worker is also employed there by another employer established locally. What counts is the expectation at the time of the posting. Article 6 of the same agreement, subject to the rest of that title, applies the laws of the state where the work is done, whatever the worker’s residence or the employer’s seat. And the five-year rule covers a posted worker, not a local hire, which is what the employee in Austin is.
The protective return and the disclosure that goes with it
Where the position is that no permanent establishment exists, it still has to be taken somewhere. A foreign corporation that determines its limited United States activities give rise to no effectively connected income may still file a return, and the instructions for Form 1120-F say it should do the same where it concludes it has no liability under a treaty, for example because its income is not attributable to a permanent establishment. The purpose is not to report tax but to safeguard the deductions and credits under section 1.882-4(a)(3)(vi) if that determination later proves wrong.
Where the position rests on the convention, section 6114 requires disclosure of a position that a treaty overrules or otherwise modifies an internal revenue law, subject to the classes of case the Secretary waives. Section 6712 imposes a penalty of 1,000 dollars on each such failure, and 10,000 dollars in the case of a C corporation, waivable for reasonable cause and good faith. The amount is not the point. A position taken openly on a return has a documented history, while a position never disclosed is one found by somebody else.
Groups sometimes resist on the theory that filing invites scrutiny. The reverse is closer to the truth. The remote employee, the payroll registration and the customer invoices already establish the presence. The filing establishes the analysis.
State exposure runs on a separate track
None of this is settled at state level by a convention. The taxes it covers on the United States side are federal, a state is not party to the treaties the federal government concludes, and the prevailing position is that the treaty does not bind it. A company with no federal permanent establishment can still owe income or franchise tax in the state where its employee lives and works, measured against a nexus standard the state writes for itself.
The federal statute that bears on state income taxation here is Public Law 86-272, codified at 15 U.S.C. section 381. It bars a net income tax, and only where the only business activities in the state are the solicitation of orders for sales of tangible personal property sent outside the state for approval and, if approved, filled by shipment or delivery from a point outside the state, or the solicitation of orders in the name of or for the benefit of a prospective customer whose own orders to the company would meet that description. A software company, a services business and a licensor all sit outside it, because none of them sells tangible personal property.
What to decide at the point of hiring
Three decisions carry most of the outcome. The first is what the person will actually do, since a support engineer answering tickets and a sales lead negotiating terms are not the same fact pattern, and the job description is the first evidence anyone will read. The second is whether the person will hold, in substance, authority to conclude contracts in the name of the enterprise, and whether the group is prepared to keep that authority in Europe and to record that it did. The third is whether the group would rather accept a United States subsidiary, price its intragroup services at arm's length and take the certainty.
None of those is a tax decision in isolation. They are decisions about how the business is run, and the tax result follows the answer rather than the other way round. That is why the analysis belongs at the point of hiring, when it is inexpensive, rather than at the point of audit, when it costs the tax, the interest, the penalties and the deductions.
