Do sales reps in California create sales tax nexus below the Wayfair threshold?

Why people beat thresholds, and how little presence it takes

The rule that representatives create collection obligations is much older than Wayfair and survived it untouched. The Supreme Court sustained a use tax collection duty based on independent commission brokers in Scripto, Inc. v. Carson (1960) 362 U.S. 207, where ten independent contractors soliciting orders in Florida were enough, and in Tyler Pipe Industries, Inc. v. Washington State Department of Revenue (1987) 483 U.S. 232, a gross receipts tax case, the Court adopted the Washington Supreme Court's test that in-state activities significantly associated with the seller's ability to establish and maintain a market suffice, there performed by an independent contractor acting on the seller's behalf. California's own authority runs the same way. In Felt & Tarrant Mfg. Co. v. Gallagher (1939) 306 U.S. 62, the Supreme Court upheld California's power to require an out-of-state manufacturer selling through commission-paid agents in California to collect the state's use tax, and in Borders Online, LLC v. State Board of Equalization (2005) 129 Cal.App.4th 1179, the Court of Appeal applied section 6203(c)(2), holding that an affiliate's California stores accepting returns acted as the online retailer's agent for the purpose of selling, and observing that "there is no requirement that the out-of-state retailer's in-state representative be engaged in the solicitation of sales." Wayfair removed the physical presence floor for states that want to reach pure remote sellers; it did not raise the floor for sellers with presence.

The listed activities go beyond selling to delivering, installing, assembling, and taking orders, so the rule catches more than classic sales reps: the manufacturer's independent rep group carrying the line into California showrooms, the commissioned agent who writes orders at a trade market, the contractor who installs what the company sells, the merchandiser who stocks and maintains displays. What ties each of them to the seller is that they operate under the authority of the retailer or its subsidiary, the element that separates a representative from an unaffiliated dealer buying and reselling for its own account. A seller's own characterization of the relationship, independent contractor rather than employee, changes nothing, since the statute names independent contractors expressly. Two carve-outs narrow the list. A contractor used only for warranty or repair work on property the retailer sold does not by itself create the obligation, unless the contractor and the retailer have substantially similar ownership (Cal. Code Regs., tit. 18, section 1684(d)(2)). Trade shows are the statutory exception: a retailer whose only physical presence in California is convention and trade show activity, as described in Internal Revenue Code section 513(d)(3)(A), is not engaged in business through its representatives if that activity does not exceed 15 days, in whole or in part, in any 12-month period and the retailer did not derive more than $100,000 of net income from it in California in the prior calendar year, but it must still collect use tax on sales made at the show and on orders taken at or during it (Revenue and Taxation Code section 6203(d); Cal. Code Regs., tit. 18, section 1684(d)(3)). A permanent showroom is a different matter: it is a sales or sample room under section 6203(c)(1), not trade show activity.

Beyond the listed activities, any physical presence in California raises a presumption that the retailer is engaged in business, which the retailer can rebut only by showing that its presence is so slight that the Constitution bars a collection duty (Cal. Code Regs., tit. 18, section 1684(b)(2)), and the California Department of Tax and Fee Administration has treated employee visits to California customers once or twice a year as enough (CDTFA Annotation 220.0245). A nonprecedential Office of Tax Appeals opinion illustrates the pattern on this article's own question: a small out-of-state seller that argued its sales were well within the $500,000 threshold was held to the duty to collect, principally because it already held a use tax registration, with the panel also finding that installations were performed in California on its behalf and that the seller had not rebutted the presumption (Appeal of Doors On-Line, Inc., OTA No. 20025866 (May 26, 2021), nonprecedential; the periods at issue predated the threshold).

For completeness, a seller comes within the statewide collection obligation through a place of business or property in the state, such as an office, sample room, warehouse, or inventory it owns or leases there (Revenue and Taxation Code section 6203(c)(1); Cal. Code Regs., tit. 18, section 1684(c)(1)(A)); through people operating in the state under the rule above (section 6203(c)(2)); through rentals from property it leases in the state (section 6203(c)(3)); or through the economic threshold (section 6203(c)(4)). The statute presents these as included in, not a limit on, the substantial nexus it reaches. Separately, the marketplace facilitator law treats the platform as the seller and retailer for the sales it facilitates (section 6042), so marketplace sales sit on the platform's return while the seller's direct sales remain its own question. Statewide collection is not the end of the inquiry, though, because the district taxes run on their own engaged-in-business test, and there the half-million-dollar figure governs even for a seller already inside through its people. Revenue and Taxation Code section 7262 treats a retailer with more than five hundred thousand dollars in combined sales of tangible personal property in California or for delivery into California as engaged in business in every district in the state, and the Department's regulation on collection of district use tax by retailers (Cal. Code Regs., tit. 18, section 1827) confirms what follows: a retailer over that line collects the district use tax on all of its deliveries into every district that imposes one, while a retailer below it collects a given district's tax only where it is engaged in business in that particular district. The rep force therefore answers whether the seller collects at all; the dollar test still answers, separately, how much of the district map it collects across, and a seller that set the threshold aside because its agents already created nexus will have under-collected district tax rather than avoided a question.

Software sellers from January 1, 2027

Senate Bill 122 (Stats. 2026, ch. 23) brings software sellers into this analysis. From January 1, 2027, amended Revenue and Taxation Code section 6016 includes a digital product in tangible personal property, and new section 6016.1 defines a digital product as prewritten computer software transferred on tangible storage media, transferred electronically, or accessed remotely, with exclusions for digital audio, audiovisual works, books, video games, and other categories. Because those definitions govern the whole Sales and Use Tax Law (section 6002), a software seller's California representatives will operate for the purpose of selling tangible personal property within section 6203(c)(2) from that date, at any sales volume. SB 122 does not amend or mention section 6203, and the Department has published no guidance on the point, so this is a reading of the statutes rather than a stated agency position. Software sales also enter the count for the $500,000 thresholds in sections 6203(c)(4) and 7262, but how "for delivery in this state" applies to remotely accessed software is unresolved: no statute, regulation, or published Department guidance addresses it. The first-dollar rule carries a software caveat as well: once one purchaser's electronically transferred or remotely accessed digital products from a single retailer exceed $5,000,000 in a calendar year, the retailer is relieved and the purchaser self-assesses under a use tax direct payment permit (sections 6052 and 6201.55). The library's companion article on SaaS taxability under Senate Bill 122 covers the new rules in full.

The distinction that catches sophisticated companies: no P.L. 86-272 for sales tax

A company that knows the federal solicitation statute protects it from state income tax where its reps only solicit orders may assume the same shield covers sales tax. It does not, and the two regimes are opposites by design. Public Law 86-272 restrains only taxes measured by net income; a sales tax collection obligation is not a tax on the seller's income but a duty to collect the customer's tax, and the federal statute has nothing to say about it. So the identical fact pattern, independent reps soliciting orders in California that are accepted and filled from outside the state, produces a split answer: protected from California income tax, if the reps stay inside pure solicitation as the companion Public Law 86-272 article maps, and simultaneously obligated to collect California use tax from the first taxable sale. The split runs the other way too: a pure remote seller crossing the economic threshold has collection duties while possibly remaining income-tax protected. Any nexus review that produces one answer per state instead of one answer per state per tax has compressed away the distinction that matters.

Which tax the seller collects depends on the facts. An out-of-state retailer whose reps solicit orders that are accepted and filled outside California registers for a Certificate of Registration-Use Tax and collects use tax from its customers (Cal. Code Regs., tit. 18, sections 1684(a), (e)(1) and 1620(a)(2)(B)). Sales tax applies instead where an in-state branch, office, outlet, or other place of business participates in the transaction in any way, and the regulation counts as an other place of business the homes of district managers, service representatives, and other resident employees who perform substantial services in relation to the retailer's functions in the state (Cal. Code Regs., tit. 18, section 1620(a)(2)(A)). The difference matters at the exit.

The stakes of getting it wrong are asymmetric in sales tax, because the obligation runs from when the nexus facts began, not from discovery. For a seller that never filed, the deficiency period reaches back eight years rather than the usual three (Revenue and Taxation Code section 6487), with no limit where fraud or intent to evade is established. The tax the seller was required to collect is its own debt to the state (section 6204); a seller that never filed receives a determination based on the Department's estimate, with a 10 percent penalty for failure to file (section 6511); and it has 30 days after service of the notice of determination to petition for redetermination, after which the determination becomes final (section 6561). That arithmetic, years of somebody else's tax absorbed as a cost with interest, is what makes voluntary disclosure, with its limited lookback and penalty relief, the usual route to evaluate for a seller whose rep history predates its registration. The Department's out-of-state program is open only to a retailer located outside California that has not previously registered with the Department, is engaged in business under section 6203, voluntarily registers, has not been contacted by the Department or its agents regarding section 6203, and whose failure to file was due to reasonable cause and not negligence or intentional disregard of the law (section 6487.05(a)). Registration is the first step of that program, not a disqualifier: the application, form CDTFA-38, is due within 30 days after the seller registers, and the form states that a seller may not qualify if the application is not submitted within that window. A qualifying retailer's lookback is three years rather than the eight that apply to a nonfiler, and penalty relief requires a statement under penalty of perjury (section 6487.05). The Department's program description excludes sales subject to California sales tax and any person that holds or held a seller's permit, so a seller with home-based reps should not assume the program is available: the homes of resident employees performing substantial services can be places of business that make the sales subject to sales tax (Cal. Code Regs., tit. 18, section 1620(a)(2)(A)).

Practice notes

The intake question for any seller with California customers is not the sales number but who and what touches California: employees, rep groups, commissioned agents, installers, merchandisers, trade show staff, and what each of them does, in writing, along with any office, warehouse, inventory, or leased property in the state. The sound practice maps that answer to the routes in section 6203(c), place of business or property, people, leased property, and the economic threshold, per period, with marketplace sales tracked separately, because nexus is dated and the exposure computation depends on when each route opened; trade show activity is tested against the 15-day and $100,000 limits of section 6203(d) before it is counted, and warranty-only contractors against the ownership test in Regulation 1684(d)(2). The district footprint is its own question, since a seller over the half-million-dollar line collects district tax on every California delivery no matter which route brought it in. The two-tax discipline holds throughout: every state conclusion issued as a pair, income tax and sales tax, with the federal protection analyzed only on the income side. Where rep history predates registration, the sound practice is to quantify the lookback and evaluate voluntary disclosure before the seller registers or has any contact with the Department, confirming first that no home-based employee or other in-state place of business makes the sales subject to sales tax, and then to register and file form CDTFA-38 within 30 days. Software sellers run the same intake ahead of January 1, 2027. The threshold chart belongs in its proper role: a screening tool for pure remote sellers and, for sellers already inside on other grounds, an input to the district footprint rather than to the registration question, consulted after the people questions, never instead of them.
