StubHub: The Platform’s Actual Role Made It a Wisconsin Sales-Tax Seller

Calling a business an online marketplace did not keep it outside Wisconsin’s sales-tax law. In StubHub, Inc. v. Wisconsin Department of Revenue, 2026 WI App 7, No. 2024AP455 (Jan. 13, 2026), the Wisconsin Court of Appeals examined what StubHub actually did when tickets changed hands. It held that the platform was a person selling taxable admissions during 2008–2013 and was also subject to a nonfiling penalty. The court reversed the circuit court’s order, which had relieved StubHub of the tax.

Subsequent history: The court issued errata on February 19, 2026, correcting paragraphs 29 and 31; this analysis uses the corrected opinion. The Wisconsin Supreme Court denied review on September 10, 2026. This is a Wisconsin statutory decision about the stated audit years, not a ruling that every platform owes California tax or that every later marketplace statute applies retroactively.

The platform handled the exchange without owning the tickets

Ticketholders chose the ticket price and generally could withdraw a listing or sell elsewhere. The Instant Download option was an exception: It required an exclusive listing with StubHub. StubHub did not buy tickets for its own inventory. Those facts supported its description of itself as a facilitator rather than a seller. But they were only part of the transaction. Official opinion, paragraphs 2–4.

The buyer paid the listing price and StubHub’s fees to StubHub. StubHub processed the payment, deducted its fees and sent the balance to the ticketholder. It supplied delivery instructions for paper tickets and direct access for electronic tickets. Some sports tickets used barcode integration to issue the buyer a new ticket. Buyers and ticketholders generally did not know each other’s identity. StubHub also promised replacement tickets or a refund under its FanProtect Guarantee if specified delivery or validity problems occurred. Paragraphs 4–6.

Nearly $154 million in ticket sales for Wisconsin events passed through the platform during the audit period. The record did not establish that buyers paid sales or use tax on those resales or that StubHub paid it. Although the parties considered tax on the original purchases highly likely in most cases, the opinion did not treat that stipulation as proof that tax had been paid on the later transactions. Paragraphs 7–8.

The tax and the penalty followed different paths through review

After an audit, the Department of Revenue assessed about $8.50 million in back taxes and another $8.57 million in interest, penalties and fees. The Wisconsin Tax Appeals Commission upheld tax liability. It found StubHub’s transaction fees, transfer procedures and software went beyond a passive marketplace role. But the Commission rejected the penalty, reasoning that the department’s published guidance had not adequately alerted StubHub to the obligation. Paragraphs 8–11.

Both sides sought circuit-court review. The circuit court found the tax statute ambiguous and ruled that StubHub was not subject to the tax; it therefore did not reach the penalty. On the department’s appeal, the Court of Appeals reviewed the agency decision rather than simply deferring to the circuit court. It reviewed statutory interpretation and summary judgment independently, while distinguishing the treatment of disputed agency factual findings. Paragraphs 12–16.

The court identified the seller by identifying who effected the sale

Wisconsin taxed retail sales of admissions to amusement, athletic, entertainment and recreational events. The difficult question was who counted as the person selling. Defining a seller as every person selling did not, by itself, answer StubHub’s objection. The court considered the statutory definition of a sale and ordinary definitions centered on a transfer in exchange for money. Paragraphs 18–22.

That approach made the platform’s conduct decisive. StubHub was the entity the buyer encountered. It conducted the transaction, charged the buyer, retained its fees, transferred the remaining payment and provided the means or instructions for ticket delivery. The court concluded that StubHub effected the transfer for payment and therefore was a seller. It rejected the company’s comparison to an auctioneer or merely passive facilitator. Paragraphs 23–24.

The holding did not require a finding that StubHub first owned the ticket. Nor did the appellate court adopt every alternative theory offered by the department. Once the statutory and ordinary definitions resolved seller status, the court declined to address the department’s undisclosed-principal theory and its separate retailer argument for some sales. Paragraph 35. The court’s seller analysis, rather than those alternative theories, supplies the basis for its result.

The later marketplace law did not establish a prior exemption

StubHub argued that Wisconsin’s 2019 Marketplace Provider Law created its tax obligation. If the legislature needed a new law, the company reasoned, the earlier law had not covered it. The department answered that the amendment clarified an already broad definition. Paragraphs 25–28.

The court recognized a presumption that an amendment changes the law, but explained that the presumption can be rebutted by evidence of clarification. It examined the department’s proposed legislation and its explanation that certain businesses had been ignoring assessments. It also relied on an earlier Wisconsin decision treating specific additions to a broad retailer definition as clarification. In this setting, the added marketplace definitions made existing coverage more specific instead of establishing StubHub’s first liability. Paragraphs 29–34.

This was an interpretation of Wisconsin’s enactment and the record concerning it. It does not supply a general rule that all marketplace legislation merely clarifies old law. For an assessment spanning a statutory change, the relevant questions remain the language in effect for each period, the transaction at issue and what the particular amendment did.

The penalty analysis compared the guidance with the transaction

The court separately considered the 25% nonfiling penalty. The statutory framework required the department to show willful neglect rather than reasonable cause. The department relied on a published tax bulletin explaining a ticket broker’s obligation. Paragraphs 36–39.

Example 19 described a ticketholder who set the price, gave a broker the right to sell tickets on its website, retained possession and shipped at the broker’s direction. The broker sent the proceeds to the ticketholder after deducting a commission or fee. The bulletin assigned sales-tax responsibility to the broker. StubHub and the Commission focused on whether the label “ticket broker” gave adequate notice. The court instead read the complete example and found the described transaction fit StubHub’s operations. It concluded that the penalty applied. Paragraphs 39–41.

The useful distinction is between disagreeing with a label and showing why published guidance does not describe the business’s conduct. The latter requires the actual user agreement, payment flow, delivery process and guidance for the years in dispute. A business name or general description of its industry does not answer those questions.

Keep seller status, nexus and the appeal procedure separate

StubHub addressed who was selling under Wisconsin law. Our Wayfair analysis addresses the different constitutional question of sales-tax nexus without physical presence. Neither answer replaces the other. A California assessment also has its own notice and review procedures, discussed in our CDTFA dispute guide.

For a platform or business reviewing an assessment, preserve the agreements and transaction records that applied during the audit years, not only today’s website terms. Separate the tax calculation from the asserted penalty and its evidentiary basis. Those records allow counsel to examine the state’s actual theory and the available response.
