Does Public Law 86-272 protection reach a state's minimum franchise tax?
Edvin Givargis Published 9 minute read
The short answer
No. Public Law 86-272 bars a state from imposing a net income tax on a company whose only activity in that state is the solicitation of orders for tangible personal property, approved and shipped from outside the state (15 U.S.C. sections 381 through 384). It says nothing about any other kind of tax, and states have never pretended otherwise: a franchise tax measured by capital or net worth, a gross receipts tax, or a flat, fixed-dollar minimum tax imposed simply for the privilege of doing business in the state falls outside the statute because it is not, in the statute's own terms, a tax measured by net income. A company can therefore be fully protected against a state's net income tax and still owe that state's minimum franchise tax, in the same year, based on the same facts, because the protection and the tax are answering different questions: one asks what the state may tax based on income, the other asks what the state may charge for the privilege of being present and transacting business at all, however that charge is measured. A nexus study that treats "PL 86-272 protected" as the end of a state's analysis has stopped one step too early.
What the statute actually says, and what it never claimed to cover
Public Law 86-272 is narrow by design, and the narrowness is textual, not a matter of generous or stingy interpretation. The operative provision bars a state from imposing "a net income tax" on income derived from interstate commerce where the only business activity in the state is solicitation of orders for tangible personal property that are sent outside the state for approval and, if approved, filled by shipment from outside the state. A companion section defines "net income tax" for purposes of the act as a tax imposed on or measured by net income. That definition is doing real work: it draws a line between taxes computed on some measure of net income after expenses and taxes computed on anything else, gross receipts, capital, net worth, the number of authorized shares, or simply a flat amount for the privilege of qualifying to do business, and only the first category is inside the statute's protection. States that impose a business tax measured by something other than net income were never relying on an exception to Public Law 86-272 when they collected it from a solicitation-only seller; they were imposing a tax the statute never reached in the first place, because Congress wrote the protection around net income taxation specifically, at a time when net income taxation was the primary way states taxed multistate businesses, and never extended it to the other tax bases states have used before and since. The Supreme Court's discussion of the statute's scope, in the context of what activities remain protected solicitation, underscores the same point from a different angle: the protection Congress granted is precise and limited to its terms, not a general immunity from state taxation for companies that keep their in-state footprint to sales solicitation.
Why a protected seller can still owe a minimum tax
The practical consequence shows up whenever a state does two things at once, which is common: it imposes a net income tax that Public Law 86-272 can shield, and it separately imposes a franchise, privilege, or minimum tax that is not measured by net income and is triggered by the state's own doing-business or economic nexus standard rather than by income tax nexus specifically. A seller whose only in-state activity is protected solicitation of orders for goods shipped from outside the state has, by hypothesis, no state income tax exposure in that state; the statute does exactly what it was written to do. But if the same state also imposes a flat minimum tax, a capital-based franchise tax, or a gross receipts tax on any corporation meeting its own separately defined threshold for being subject to that tax, whether measured by physical presence, a dollar amount of sales, or simply having qualified or registered to transact business, the seller's protected solicitation activity does not answer that question at all, because the minimum tax was never conditioned on net income in the first place. This is precisely why a well-built nexus study workpaper carries two separate determinations for the same state: one column asking whether net income is protected under the federal statute, and a later column asking, independently, whether the state imposes a franchise or gross receipts-type tax and what the resulting liability would be. Those two columns are not redundant and are not in tension when they produce different answers for the same state; they are correctly modeling two different legal questions that happen to share the same set of underlying facts. California illustrates the pattern cleanly: a corporation can be fully shielded from California's net income tax under the federal statute while still meeting California's own factor-presence doing-business standard on sales, payroll, or property, which triggers the state's $800 minimum franchise tax regardless of the income tax outcome, because the minimum tax is a flat charge for the privilege of doing business in the state and was never measured by net income to begin with. New Hampshire runs the sharper version of the trap by stacking its two business taxes side by side: the business profits tax is measured by net income and yields to the federal statute, while the business enterprise tax is measured by the enterprise value tax base, the compensation, interest, and dividends the business pays, which is not net income under any reading, so a solicitation-only seller can be fully protected against one New Hampshire business tax and owe the other on the same facts in the same year (RSA chapters 77-A and 77-E). This is where substandard nexus studies do their damage, and the pattern is common enough to name. A study arrives reporting a single protected verdict per state, the company files nothing and reserves nothing on the strength of it, and the assessment that eventually arrives comes from the very state the study said could not reach the company. The study was not wrong about the statute; it was wrong about the question, because it never separated the tax the statute reaches from the taxes it does not.
Gross receipts taxes: the largest category of miss
The costliest version of the error involves no minimum tax at all. A gross receipts tax is measured by receipts rather than net income, which places it outside the federal statute's protection entirely, and the states that rely on one tend to rely on it heavily. Washington is the standing example. Its business and occupation tax is imposed on the act or privilege of engaging in business in the state and measured by gross proceeds of sales or gross income of the business (RCW chapter 82.04), and Washington imposes no corporate net income tax at all, so a seller whose in-state activity is protected solicitation has no Washington tax for the federal statute to protect it from and full exposure to the tax Washington actually imposes. The exposure builds quietly, a modest rate against an unreduced receipts base, year after year, with no return ever filed to start a limitations period running, and it tends to surface at the worst possible moment: transaction diligence. An unreserved, multi-year gross receipts exposure across a target's Washington revenue is the kind of schedule line that reprices a deal or ends it outright, precisely because the target's file says protected while the diligence team's arithmetic says owed. Washington then adds a layer that even careful state-level analyses miss: a number of Washington cities impose their own separate business and occupation taxes, locally administered under the state's municipal framework (RCW chapter 35.102), with their own registration, apportionment, and filing obligations, so resolving the state tax resolves nothing at city hall and the same receipts can owe both. Other jurisdictions repeat the pattern in their own vocabularies, gross receipts and commercial activity taxes that never met a solicitation shield, and the discipline is the same throughout: the federal statute answers one question about one kind of tax, and every other tax a state or city imposes gets its own line in the study or the study is not finished.
Why the two-question structure matters for the exposure number
Treating "protected" as a single, state-level verdict rather than a tax-by-tax determination produces an exposure estimate that quietly drops liability on the table. A study that stops after concluding a state's net income tax is protected will report that state as clean, when the correct conclusion may be that the state's largest tax is fully avoided and its minimum or franchise tax is still owed, sometimes for open prior years, because that tax's own nexus and lookback rules were never separately tested. The reverse mistake, though rarer, does damage in the other direction: an unprotected income tax conclusion in a state that has no separate minimum tax at all overstates the state's total exposure relative to a state with the same income tax outcome but an additional flat charge layered on top. Neither error is really about Public Law 86-272; both come from collapsing a two-part question, is net income taxable, and is some other, differently measured tax also owed, into one answer. The discipline that avoids the error is straightforward: for every state in the matrix, resolve the net income tax question under the federal statute first, and then, independently and without reference to that answer, resolve whether the state imposes any tax not measured by net income for which the company's activity level, however protected for income tax purposes, is otherwise sufficient to create an obligation.
Practice notes
Build the nexus matrix with the net income tax question and the non-net-income tax question as genuinely separate columns, resolved independently, rather than letting a single state-level checkbox stand in for both, because the same facts routinely produce different answers to each. Identify, state by state, every tax base other than net income that the state imposes on corporations doing business there, franchise tax measured by capital or net worth, gross receipts tax, flat minimum or privilege tax, and test each one against that state's own nexus standard for that specific tax, since a state's economic or factor-presence threshold for its minimum tax need not track its income tax nexus rules at all. Do not let a client's relief at hearing that its income tax is protected become the final word before the minimum tax question has actually been asked and answered for every state on the list. And where prior years are in scope, remember that the minimum tax's own statute of limitations and voluntary disclosure eligibility run on their own timeline, separate from the income tax analysis, so a lookback computed only for the protected-or-not income tax question will understate the total prior-year exposure if a minimum tax was quietly accruing underneath it the entire time.
