A Dutch subsidiary is the least controversial thing an American group can own. It pays corporate income tax in the Netherlands at 19 per cent up to 200,000 euro of taxable profit and 25.8 per cent on the excess, it files its own accounts, and for the first years it usually distributes nothing. The American shareholder’s tax position may be entirely unremarkable.
The obligation that goes wrong is not a tax. It is Form 5471, the information return for United States persons with respect to certain foreign corporations, and its penalty regime attaches to the failure to furnish information rather than to any tax that was due. The failures we are asked to remediate are almost never the result of a decision. They are the result of nobody having identified which category of filer the client fell into, in a year when the answer changed.
The form is not one obligation but several
Form 5471 is a container. Which schedules a filer completes, and what information must be assembled, depends on the category assigned, and the categories are cumulative rather than exclusive. The instructions direct a filer described in more than one category not to duplicate information but to complete all items that apply, so a single person can file in more than one category for the same corporation in the same year.
The December 2025 revision of the instructions sets out categories 1a to 1c for United States shareholders of specified foreign corporations under section 965, category 2 for officers and directors, category 3 for certain acquisitions and dispositions, category 4 for persons in control, and categories 5a to 5c for shareholders of controlled foreign corporations. In the files that reach us, the categories in issue are almost always 3, 4 and 5.
The distinction that matters commercially is between the transactional categories and the status categories. Category 3 fires on an event. Categories 4 and 5 recur every year for as long as the relationship subsists. A group that filed once at incorporation and stopped has usually confused the two.
Category 3, the acquisitions that start the clock
Category 3 applies to a United States person who acquires stock which, added to stock already owned on the date of acquisition, meets the 10 per cent stock ownership requirement, and section 6046(a)(2) sets that requirement at 10 per cent or more of the total combined voting power of the classes entitled to vote, or 10 per cent or more of the total value of the stock. It applies as well to a person who acquires stock that meets the requirement without regard to stock already owned, to a person treated as a United States shareholder under section 953(c), to a person who becomes a United States person while meeting the requirement, and to a person who disposes of enough stock to fall below it. The filer completes Part II of Schedule O and attaches a statement of the foreign corporation’s indebtedness to the related persons identified in the regulations and of the subscribers to its stock.
Becoming a United States person is the trigger that surprises people. An individual who owns a Dutch company and then becomes an American resident has acquired nothing. The filing obligation arises because their own status changed while the shareholding stayed exactly where it was.
Disposition is also a trigger. The regulation reaches a person who disposes of sufficient stock to reduce the interest below 10 per cent of voting power or of value, so selling down through the threshold is a reportable event in the year of the sale, which means the last filing in a relationship often falls due after the client has stopped thinking about the entity at all.
Category 4, and what control means
Category 4 covers a United States person who had control of the foreign corporation during its annual accounting period. The regulation requires a return for each annual accounting period of each foreign corporation that the person controls at any time during that period, and it defines control as ownership, at any time during the person’s taxable year, of stock possessing more than 50 per cent of the total combined voting power of all classes entitled to vote, or more than 50 per cent of the total value of the shares. The test is one of fact at a moment rather than of duration, so control held briefly inside the accounting period is enough to bring the year into charge.
Two features of that test do the damage. It is disjunctive, so a person can control on value without controlling on votes, and a Dutch structure using different share classes for economics and for governance can produce control where the cap table suggests otherwise. And it is measured by attribution as well as directly, because section 6038(e)(2) applies the constructive ownership rules of section 318(a) for this purpose, subject to modifications that stop a United States person being treated as owning stock owned by a person who is not a United States person and that substitute 10 per cent for 50 per cent in section 318(a)(2)(C).
Category 4 carries the widest reporting burden of any category. The filing requirements chart in the instructions marks eighteen of its twenty rows for a Category 4 filer, everything except the two parts of Schedule O, and among them are Schedules C and F, the income statement and the balance sheet of the foreign corporation, which are required of categories 3 and 4. Schedule M sits there alone: every United States person described in Category 4 must file it, no other category does, and it reports the transactions that occurred during the foreign corporation’s annual accounting period, translated using the average exchange rate for that year under section 989(b). The information is ordinary Dutch bookkeeping, but it has to be restated in dollars and on American principles.
Category 5 and controlled foreign corporation status
Section 957(a) defines a controlled foreign corporation as a foreign corporation in which United States shareholders own more than 50 per cent of the total combined voting power of the voting classes, or of the total value of the stock, on any day of its taxable year, ownership being measured within the meaning of section 958(a) and by applying the rules of section 958(b). A United States shareholder under section 951(b) is a United States person who owns, within those same meanings, 10 per cent or more of voting power or of value.
The two thresholds work together in a way that is easy to model wrongly. Holders below 10 per cent are not counted in the more than 50 per cent test. A Dutch company with a dispersed American register in which no holder reaches 10 per cent, and in which nothing is attributed to anyone under section 958(b), does not become a controlled foreign corporation under section 957(a) on that register alone, and one with three American holders at 20 per cent each does.
Status is what makes the difference between reporting and paying. Once the Dutch company is a controlled foreign corporation, its United States shareholders come within the anti deferral rules, and profits can be taxed in the United States before any dividend is declared. The relief that softens the charge is narrower than it is usually described. Section 70321 of Public Law 119-21 struck 50 per cent from section 250(a)(1)(B) and inserted 40 per cent for taxable years beginning after 31 December 2025, and section 70323 of the same Act renamed the amount that the percentage applies to, so for those years the deduction is 40 per cent of what section 250(a)(1)(B)(i) now calls net CFC tested income and what earlier years called global intangible low-taxed income. The deduction is not general. The Service records that it is allowed only to domestic corporations, which for this purpose do not include real estate investment trusts, regulated investment companies or S corporations, and to individuals who make a section 962 election, so an individual shareholder who does not elect does not reduce the charge by it. Where it applies, it is set against the 21 per cent corporate rate of section 11(b). The arithmetic that follows is the reason the status question deserves an answer before the structure is built rather than after.
What a Dutch subsidiary makes you compute
The substantive work behind the form is accounting rather than legal. Earnings and profits have to be computed on American principles for a company whose books are kept under Dutch rules, and the two do not converge on their own. The instructions require the adjustments of Regulations section 1.964-1(b) and (c) to the net book income of the foreign corporation, conforming it both to United States generally accepted accounting principles and to United States tax accounting principles. Depreciation, provisions, participation exemption treatment of subsidiary income and the treatment of formation costs all move the number.
Functional currency is the second workload. A Dutch subsidiary keeps its books in euro, the amounts have to be translated, and every exchange rate on the form is reported on a divide by convention to at least four places. Distributions produce American consequences that have no counterpart in the Dutch accounts, because foreign currency gain or loss on a distribution of previously taxed earnings is computed under section 986(c) and reported in its own right.
The third item is the related party schedule. Management charges from the American parent, intragroup loans, cost sharing and any royalty on intellectual property have to be disclosed and priced. This is where the information return meets transfer pricing, and where a Dutch file built to Dutch documentation standards has to be extended rather than translated.
The penalty, and the credit it takes with it
Section 6038(b) imposes 10,000 dollars for each annual accounting period of each foreign corporation for which the required information is not furnished within the prescribed time. Where the failure continues more than 90 days after the Service mails notice of it, a further 10,000 dollars applies for each 30 day period or fraction of one, and the increase under that paragraph cannot exceed 50,000 dollars.
The per period structure is what turns a small oversight into a serious number. A group that missed the form for a single Dutch subsidiary over five years is looking at the initial penalty five times before any continuation penalty is counted, and the same failure repeated across three subsidiaries multiplies again by entity.
Section 6038(c) adds the reduction of foreign taxes available for credit under sections 901 and 960, set at 10 per cent and increased by a further 5 per cent for each three month period or fraction of one during which the failure continues after that same 90 day period, with the reduction for any one failure limited to the greater of 10,000 dollars or the income of the entity for the accounting period concerned. For a group paying real Dutch corporate income tax, losing part of the credit is often the larger economic loss, because it converts a timing question into a permanent one. Categories 2 and 3 are obligations of section 6046 rather than of section 6038, so a failure there falls outside the penalty just described and under section 6679 instead. That provision imposes 10,000 dollars, for each reportable transaction in the way the instructions apply it, unless it is shown that the failure is due to reasonable cause, and it carries the same 90 day continuation and the same 50,000 dollar ceiling on the increase. The instructions also record that criminal penalties under sections 7203, 7206 and 7207 may apply.
The question of whether the Service could assess these penalties administratively, rather than suing to collect them, was open for a period. The Court of Appeals for the District of Columbia Circuit decided it against the taxpayer in Farhy v. Commissioner on 3 May 2024, reversing the Tax Court and holding that penalties imposed under section 6038(b), like the related penalties under section 6038(c), are assessable.
The year never closes
The consequence that most affects planning is not the penalty at all. Section 6501(c)(8) provides that where information required under a listed section, including sections 6038 and 6046, has not been furnished, the time for assessment of any tax with respect to any return, event or period to which that information relates does not expire before three years after the Service is furnished with the information.
Read that in the negative. If the form was never filed, the assessment period for the return it relates to has not started to run. A group that believes its 2018 position is closed because the ordinary period has passed is mistaken if the Form 5471 for that year is missing, and the exposure is not limited to items connected with the foreign subsidiary unless the failure was due to reasonable cause and not to willful neglect, in which case subparagraph (B) confines the extension to the items related to the failure.
This is why a missing information return is a due diligence item in every transaction involving an American shareholder. A buyer looking at an American group with European subsidiaries is not asking whether the tax was paid. It is asking whether the years are closed, and an unfiled Form 5471 is a straightforward answer that they are not.
Remediation, and the file that supports it
The remediation is unglamorous. The forms are prepared for every open year, with the schedules completed rather than left blank, and they are filed with a statement setting out the facts. Where the failure was not willful, the statement is where the reasonable cause position is made, and it has to be made on facts that existed at the time rather than on a narrative constructed afterwards.
In one mandate we reconstructed six years of earnings and profits for a Dutch operating subsidiary from statutory accounts and bank records, because the American parent had been advised at incorporation that no filing was required and had never revisited the advice. The tax at stake across those six years was modest. The exposure under the penalty and limitations provisions was not.
The general lesson is about sequencing rather than about the form. Category status changes when shareholders change, when share classes are created, when an individual moves country and when a stake is sold, and none of those events looks like a tax event to the people who carry them out. The question is answered against the register as it actually stands, not against the register as it was drawn at incorporation. Everything described above is what happens when it is not put at all.
