- All gross revenue: taxable sales, nontaxable and exempt sales, separately stated handling and transportation charges
- Sales to otherwise exempt customers such as nonprofits and government entities
- Marketplace-facilitated sales (must be included in the threshold calculation since April 1, 2020, even if the marketplace is collecting the tax)
- Sellers with physical nexus in Texas are not considered remote sellers and cannot rely on the $500,000 safe harbor
- FBA exception: a remote seller whose only Texas presence is inventory in a marketplace provider's Texas warehouse is exempt from permitting only if total Texas revenue is below $500,000 AND the marketplace provider certifies in writing it will collect and remit. Once $500,000 is crossed, the inventory independently triggers full physical nexus.
Affiliate nexus
Texas establishes affiliate nexus through an ownership-based standard under Texas Tax Code § 151.107(b), effective January 1, 2012. Nexus is triggered when an out-of-state retailer holds at least 50% ownership in a Texas entity, or is 50% owned by a Texas entity, and that Texas entity performs any of the following activities: maintains a distribution center, warehouse, or similar facility in Texas that delivers the retailer's goods; maintains a Texas business location selling substantially similar products under substantially the same business name; uses Texas facilities or employees to advertise, promote, or facilitate the retailer's sales; or accepts returns in Texas for the retailer's goods.
Texas does not have click-through nexus and explicitly declined to adopt a commission-referral model.
Physical nexus
Under Texas Tax Code § 151.107, being "engaged in business" in Texas creates nexus and encompasses a broad set of activities and presences. Any office, place of distribution, sales or sample room, warehouse, storage place, kiosk, or distribution center, whether permanent or temporary, constitutes being engaged in business in Texas.
Nexus also arises from having any employee, representative, agent, salesperson, or solicitor operating in Texas. Owning or using tangible personal property in Texas, including inventory and computer software, similarly establishes nexus. This includes inventory stored in a fulfillment center. Retaining title to software licensed to and used by Texas customers also qualifies, extending the rule to SaaS and other software arrangements. Deriving rental income from property situated in Texas is an additional basis for nexus, as is using a Texas-based broadcaster, publisher, or outdoor advertiser as an agent.
Exhibiting at any Texas trade show or conference, even a single multi-day event, constitutes being engaged in business and creates physical nexus under 34 TAC § 3.286. Merely attending such an event without exhibiting, soliciting, or taking orders does not create nexus. There is no de minimis exception to physical nexus in Texas.
Trailing nexus
Texas has no trailing nexus rule for physical nexus. A prior 12-month trailing period that had existed under former 34 TAC § 3.286(b) was retroactively repealed effective June 3, 2015. Once a seller properly terminates physical presence in Texas, the collection obligation ceases immediately. For economic nexus, a seller must demonstrate 12 consecutive months of Texas revenue below $500,000 before filing for termination.
