Does P.L. 86-272 protect a foreign corporation that sells goods into California?

What the statute protects, and the word that limits it

Subsection (a) protects a seller whose only in-state activity is solicitation of orders for tangible personal property, sent outside the state for approval and "filled by shipment or delivery from a point outside the State," where the income is derived within the state "by any person from interstate commerce" (15 U.S.C. section 381(a)). Subsection (b) removes two classes of taxpayer: a corporation incorporated in the taxing state, and an individual domiciled in or resident of it (15 U.S.C. section 381(b)). A corporation organized in Japan, Germany, or Mexico is within neither exclusion. If the inquiry stopped there, a non-U.S. seller would stand where a Nevada seller stands.

It does not stop there, because the income must be derived from interstate commerce. Goods manufactured abroad, ordered by a California customer, and shipped from a foreign port move in foreign commerce, and the statute does not say "interstate or foreign commerce." The Multistate Tax Commission's current statement reads the text the same way: "Congress explicitly applied P.L. 86-272 only to 'interstate commerce.' Therefore, by its terms, the statute does not apply to foreign commerce." The statement leaves each state free to extend the protection to foreign commerce, provided it does so consistently for inbound protection and outbound throwback (MTC Statement of Information, Article VII.A (Aug. 4, 2021)). California has not. The Franchise Tax Board's audit manual, citing Dresser, states that the immunity "is expressly limited to interstate commerce."

Dresser: the holding, and why it runs in both directions

Dresser was an export case; the library's articles on throwback and taxable in another state, and on website activities and throwback, cover that side. Pumps manufactured at a plant in Huntington Park were shipped from California to foreign customers, sold some directly and some through wholly owned sales subsidiaries working on commission. In one group of countries a subsidiary with local payroll and property solicited orders and delivered, serviced, and repaired the pumps; in another, the subsidiaries' salesmen only took orders. The Franchise Tax Board threw the sales to both groups back into the California numerator under Revenue and Taxation Code section 25135, reasoning that the taxpayer itself was not taxable in those countries and that uniformity required applying P.L. 86-272 through the regulation under section 25122.

The Board of Equalization reversed. The regulation, as the opinion quotes it, says jurisdiction to tax is not present where P.L. 86-272 prohibits the tax, and tests a foreign country's jurisdiction "as though the jurisdictional standards applicable to a state of the United States applied in that state" (Cal. Code Regs., tit. 18, section 25122(c)). The Board answered: "No such prohibition exists, however, when the income sought to be taxed is derived from foreign commerce." Its illustration was the case this article asks about. If the taxpayer "were a Canadian corporation which had sales representatives in California who merely solicited orders for pumps from California customers, and the orders were approved in Canada and filled by shipments from a Canadian factory, P.L. 86-272 would not prevent California from levying a net income tax." Because the regulation does not apply the statute to "foreign commerce with a California destination, both logic and uniformity compel the same result where, as here, the stream of commerce flows in the opposite direction."

On rehearing the Board reiterated its original holding "that the limitations of Public Law 86-272 are inapplicable to foreign commerce," rejected the Franchise Tax Board's argument that the countries lacked constitutional jurisdiction anyway, and found "a regular and systematic pattern of local sales solicitation on appellant's behalf in the foreign countries in question," so the taxpayer "would be subject to a properly apportioned income tax in these foreign countries under basic U.S. constitutional standards" (83-SBE-118). The Franchise Tax Board now applies the rule in both directions. Its audit manual tests export sales against constitutional nexus in the foreign country, and treats inbound sales from a foreign country that are "not viewed as interstate commerce" as California sales whenever the taxpayer has constitutional nexus here, with the taxpayer taxable "regardless of whether its California activities exceed solicitation of orders."

What California taxes instead

Without the federal statute, the foreign seller is tested under the state's doing-business rules. A taxpayer is doing business in California if it is organized or commercially domiciled here, or if its California sales, property, or payroll exceed the lesser of an indexed dollar amount or 25 percent of its total (RTC section 23101(b)). For 2025 the indexed amounts are $757,070 of sales and $75,707 each of property and payroll; the Franchise Tax Board had not published 2026 figures as of October 13, 2026. Sales are defined as they are for the sales factor, which assigns sales of goods to their destination, and include sales by the taxpayer's agents and independent contractors (RTC section 23101(b)), closing the independent-contractor route that subsection (c) of the federal statute leaves open. A non-U.S. manufacturer shipping more than $757,070 of product to California customers in 2025, or more than a quarter of its total sales wherever the dollar figure lands, is doing business here on that fact alone.

The bright-line test is the second definition, not the only one. The first remains actively engaging in any transaction for the purpose of financial or pecuniary gain or profit (RTC section 23101), and a foreign seller whose employees or agents solicit orders in California is engaging in transactions here whether or not its sales reach the threshold. For a domestic seller that activity is what the federal statute immunizes; for a foreign seller it is doing business, which is the audit manual's inbound rule. Constitutional nexus no longer requires physical presence: it exists when the taxpayer "avails itself of the substantial privilege of carrying on business" in the jurisdiction (South Dakota v. Wayfair, Inc., 585 U.S. 162 (2018)), and a seller with a regular California customer base has done that.

A corporation doing business in California owes the franchise tax measured by net income, at 8.84 percent for a general corporation (RTC section 23151), on income apportioned to California under the unitary rules (RTC section 25101), and never less than the $800 minimum franchise tax (RTC section 23153). The first-year exemption from the minimum tax belongs to a corporation that incorporates or qualifies through the Secretary of State; a foreign seller doing business here without qualifying does not receive it, as the library's article on foreign corporations with no California activity explains. A corporation not doing business in California but deriving income from California sources is instead subject to the corporation income tax (RTC section 23501); failing the doing-business test changes the tax rather than removing it.

Qualification with the Secretary of State is a separate question. California's qualification statute excludes interstate and foreign commerce from transacting intrastate business, along with soliciting orders that require acceptance outside the state before they become binding (Cal. Corp. Code section 191). A non-U.S. seller whose California activity is solicitation of orders accepted and filled abroad generally need not qualify, even while it is doing business for franchise tax purposes.

Why a treaty does not change the answer

A seller from a treaty country will usually have been told that it has no permanent establishment in the United States and therefore no U.S. tax on its business profits. That conclusion is federal. The business profits article of the United States model convention makes an enterprise's profits taxable only in its home state unless it carries on business in the other state through a permanent establishment (U.S. Model Income Tax Convention (2016), Article 7(1)), but the taxes covered on the United States side are "the Federal income taxes imposed by the Internal Revenue Code" (Article 2(3)(b)). The Supreme Court upheld California's worldwide combined reporting as applied to a foreign-parented group, holding that "the Constitution does not impede application of California's corporate franchise tax" to the taxpayers before it and that the foreign domicile of the taxpayer or its parent is "a factor inadequate to warrant retraction" of that position (Barclays Bank PLC v. Franchise Tax Board, 512 U.S. 298 (1994)). California's water's edge rules make the same point from the inside: treaty provisions are not followed to the extent they limit the definition or taxation of effectively connected income (Cal. Code Regs., tit. 18, section 25110(d)(2)(F)1.a.).

The non-discrimination article is broader in scope. The model applies it, notwithstanding the taxes-covered article, "to taxes of every kind and description" (Article 24(7)), and it bars taxing a permanent establishment less favorably than local enterprises carrying on the same activities (Article 24(2)). In Dresser the Multistate Tax Commission, as amicus, argued that taxing a foreign corporation in foreign commerce where a domestic corporation in interstate commerce would be protected conflicts with treaty non-discrimination provisions. The Board of Equalization said the Commission "goes much too far" in calling that result unconstitutional, noted that treaty language varies and that "there are many unanswered questions in this area," and decided nothing more (83-SBE-118). No California authority has resolved the argument since. It depends on the treaty in question, and a seller whose federal position is that it has no permanent establishment stands outside the permanent establishment clause on its own account.

The combined report, and the cost of discovering the obligation late

Once the foreign seller is a California taxpayer, the default measure is a worldwide combined report of the seller and every unitary affiliate wherever organized (RTC section 25101; Barclays). For a foreign parent with foreign subsidiaries, the worldwide measure can be a multiple of the seller's own apportioned income, which is why the water's edge election matters. An electing group limits the report to the entities described in RTC section 25110; a corporation organized outside the United States enters it only if the average of its United States property, payroll, and sales factors is 20 percent or more, or to the extent of its United States-source income and, for a controlled foreign corporation, its Subpart F income. A foreign seller that is the only California taxpayer in its group, stays below 20 percent, and has little or no effectively connected income can find that its practical liability under the election is the minimum tax, as the library's article on the water's edge exclusion of foreign corporations shows.

The election's timing rules punish late discovery. It is made by every taxpayer member on an original, timely filed return for the election year, with the prescribed notification and a return computed on a water's edge basis; once made it remains in effect until terminated, and termination before it has been in effect for 84 months requires Franchise Tax Board consent (RTC section 25113). A return filed after the due date may be an original return if no other has been filed, "but it would not be a timely filed, original return" (Cal. Code Regs., tit. 18, section 25113(b)(2)). A foreign seller that learns in year four that it has been doing business in California since year one files the back years worldwide, because no election is available for them, and elects prospectively for the first year whose original return is still timely. The back years carry the worldwide measure, interest, and the delinquency and underpayment penalties.

Two forms of relief exist, both narrower than they sound. Where a unitary group already has a valid water's edge election, a unitary corporation not incorporated in the United States that later becomes a California taxpayer solely because of the bright-line thresholds, in a taxable year beginning on or after January 1, 2021, is deemed to have elected with the other members of the group (RTC section 25113); the Franchise Tax Board reached the same result by notice for earlier years (FTB Notices 2016-02, 2017-04, and 2019-02, the last covering taxable years beginning on or before December 31, 2020). A foreign group with no prior California filer has no election to join. Separately, the voluntary disclosure program, open to an entity that has never filed a California return, is not qualified or registered with the Secretary of State, maintains and staffs no permanent facility in California, and comes forward before any contact from the Franchise Tax Board, limits the look-back to six years and allows waiver of the delinquency, late-payment, estimated-tax, and information-return penalties (RTC section 19191; Form FTB 4925 (REV 10-2025)). Neither the statute nor the application addresses a water's edge election on the returns filed under the agreement, so whether the first of them can carry a valid election is a question for the agreement, and a foreign seller weighing disclosure prices the back years on a worldwide basis until the agreement says otherwise.

The open questions

The first is the one the statute's text invites: a non-U.S. seller does not always ship from abroad. A foreign manufacturer that positions inventory in a third-party warehouse in Nevada, solicits California orders accepted at its home office, and fills them by shipment from Nevada is conducting the California leg of its business in interstate commerce on an ordinary reading. Dresser did not decide that case; its illustration assumed orders "filled by shipments from a Canadian factory." The audit manual conditions its no-protection conclusion on inbound sales "not viewed as interstate commerce," which concedes that some inbound sales by a foreign seller might be, and no California decision has addressed the point. The counterargument the seller must beat is that the character of the commerce follows the parties, not the shipping leg: a sale by a foreign corporation to a California buyer is foreign commerce wherever the goods sit. A foreign seller in that posture has an argument, not an answer, and because the bright-line sales test applies regardless, the argument goes to the measure of the franchise tax, not to the filing obligation.

The second is the foreign seller below every threshold, with no California property or payroll and no one soliciting in the state. It is not doing business under either definition, so the question becomes whether it derives California-source income subject to the corporation income tax and whether the Constitution permits the state to reach it. The domestic dispute over whether cookies, chat functions, and post-sale electronic support defeat protection has no bearing on either seller; neither was protected to begin with.

Practice notes

The analysis for a non-U.S. seller of goods into California begins with the shipping point and the sales figure, not with the federal statute. Goods shipped from outside the United States move in foreign commerce, and the seller is tested under RTC section 23101 as any other taxpayer would be, with the indexed sales threshold measured at destination and inclusive of sales through agents and independent contractors. A seller over the threshold, or with people soliciting in the state, is doing business, owes the franchise tax on apportioned income with the $800 floor, and files a California return whether or not it must qualify with the Secretary of State. The federal permanent establishment conclusion does not carry over to California, and any treaty non-discrimination argument is built treaty by treaty. The water's edge election is evaluated at the first timely return, because it cannot be made on a late one; a group that discovers the obligation after the fact computes the back years worldwide, considers voluntary disclosure for the penalty relief and the six-year limit while it remains unqualified, uncontacted, and without a staffed California facility, and treats any election under the agreement as a term to be negotiated rather than a right. A seller that ships from a warehouse inside the United States documents that fact year by year, because it is the one set of facts on which the interstate commerce argument can be built.
