Comptroller Moves to Drop Texas Marketplace Fee Tax

Estimated Time to Read: 6 minutes

Texas Comptroller Don Huffines (R) announced on September 30 that his office will amend Comptroller Rule 3.330 to exclude marketplace and platform fees from taxable data processing services. The change would cover fees paid to the platforms that connect sellers with customers, including those used by online retailers, delivery services, short-term rental hosts, ride-hailing and vehicle-sharing drivers, and pet care and household service providers.

For sellers, the proposal promises lower costs. For policymakers, it reopens a question Texas has never clearly answered: who decides what counts as a taxable service, the Legislature or the comptroller?

What the Proposal Would Change

Texas has taxed data processing services since 1987, with 20 percent of each charge exempt. In 2024, then-Comptroller Glenn Hegar (R) proposed updating Rule 3.330 to say that marketplace services may qualify as taxable data processing. The test was whether they involve computerized entry, retrieval, search, compilation, manipulation, or storage of information the seller supplies. The rule's examples include storing product listings and photographs, maintaining transaction records, and compiling analytics. That provision took effect October 1, 2025.

The tax falls on the seller's purchase from the platform, not on the customer's purchase from the seller. Huffines would remove those fees from the data processing category. Sellers would still pay whatever their platform agreements require, but the state would stop taxing those charges.

The relief is not yet in place. Huffines has directed the agency to publish the amendment in the Texas Register, which opens a 30-day public comment period. The announcement does not set an effective date, define which charges qualify, or say whether previously collected taxes will be refunded. Those details will decide whether businesses get straightforward relief or another round of uncertainty.

Double Taxation or Two Transactions?

Huffines calls the tax double taxation. Hegar defended it as a tax on two separate purchases: the customer buys a product, and the seller buys services from the marketplace. Each description captures part of the picture. The state is not taxing the same purchase price twice, but it is adding a second layer of tax to a single commercial exchange. Taxes on business inputs tend to pile up as goods move toward the final consumer. Sellers either absorb that cost through thinner margins or pass some of it along to customers.

The harder question is what sellers are actually buying. Rule 3.330 excludes data processing that is ancillary to another service and has no separate value. A seller paying a marketplace is arguably buying access to customers and help completing sales, with software doing the work in the background. Software now runs through nearly every business function, so where Texas draws this line will matter well beyond marketplaces.

This dispute is also separate from the debate over collecting sales tax on online purchases. Taxing online and in-store retail sales the same way says nothing about whether the intermediary's fee should be taxed too.

Who Should Decide

Hegar argued the fees were already taxable under existing law. He noted that some platforms were collecting the tax before the rule update. He also cited the Legislature's failure in 2023 to pass House Bill 5070 (HB 5070), authored by State Rep. Angie Chen Button (R-Garland), and Senate Bill 2280 (SB 2280), authored by State Sen. Charles Perry (R-Lubbock). Both bills would have excluded marketplace fees from data processing, and neither passed out of committee despite hearings in the House Ways and Means and Senate Finance Committees. The Legislative Budget Board's (LBB) fiscal notes for the bills projected $47.7 million less in state general revenue over the 2024–25 biennium, with annual losses topping $30 million by 2027 and local governments forgoing several million more each year.

Huffines argues the prior interpretation stretched the tax beyond what lawmakers intended. Neither position settles the matter. The fiscal notes show the revenue at stake, not whether the fees were properly taxable. Calling a rule a clarification doesn't make it lawful, and bills that stall in committee are not a legislative finding that the fees were always taxable.

The comptroller does have real authority to interpret which services are taxable, so an administrative exclusion is not automatically an unauthorized exemption. But that authority does not allow an officeholder to widen or narrow a tax to suit a policy preference. The final amendment should explain why marketplace fees fall outside taxable data processing. That explanation should apply equally to comparable services, from established platforms to small competitors and new business models. Correcting an overreach is legitimate. Carving out an exception for whichever industry is best organized is not.

The underlying problem is a broadly worded statute that leaves a major tax question to whoever holds the office. Businesses should not face materially different obligations each time agency leadership changes. That concern drives the Texas Liberty Compact's Restore Legislative Supremacy plank, which calls for clearer statutory language, legislative approval of major agency rules, and independent judicial review of statutory interpretation. Applying that principle consistently means scrutinizing agency decisions whether they raise taxes or lower them. Lawmakers should settle the marketplace question in statute so the answer outlasts any single comptroller.

What It Means for Businesses

For sellers who process many transactions, the savings can add up. The money could go toward equipment, hiring, or more competitive pricing, and clearer rules would reduce the time spent classifying platform charges. Lower consumer prices are possible but not guaranteed, because competition, platform contracts, and other costs will shape how businesses use the savings.

The Bigger Picture

A broad sales tax base is often defended as fair and consistent. But a broader base does not mean a lighter burden if the new revenue funds new spending.

That is the deeper issue behind this debate. Disputes over which transactions are taxable happen because government keeps looking for revenue to support what it has already committed to spend. The sums involved here are modest next to the state budget and easily absorbed by a government willing to restrain its growth. A state that spends less has less reason to push taxes into new corners of the economy, and less temptation to let agencies do it through rulemaking.

The same caution applies to property tax relief. Texas Policy Research supports eliminating property taxes, and using available revenue to buy them down can help get there. However, keeping a questionable tax because its proceeds could fund relief leaves the legal question unanswered. Swapping property taxes for higher sales taxes also doesn't reduce what Texans pay unless spending falls too. Relief needs to come with state and local spending restraint, plus safeguards that keep taxing entities from rebuilding the burden.

Huffines' proposal is a chance to lower business costs and rethink how an older tax applies to the digital economy. Its value will depend on the final language, how it is implemented, and how past collections are treated. The larger lesson is that lasting relief requires clear laws, set by the Legislature and applied consistently, along with discipline in what government spends.
