Texas requires all foreign entities (businesses formed outside Texas) to register with the Texas Secretary of State before "transacting business" in the state.
According to the Texas Business Organizations Code (TBOC) Chapter 9, any entity not formed under Texas law must obtain registration when conducting activities that go beyond passive ownership or mere internal affairs.
This includes corporations, LLCs, limited partnerships, business trusts, and any entity type that would require a certificate of formation if formed in Texas.
Texas's standards for determining "transacting business" obligations focus on whether a foreign entity engages in activities within the state that go beyond passive ownership or mere internal affairs.
The test emphasizes the regular and continuous nature of business activities, requiring entities to register when conducting repeated transactions or maintaining ongoing operations that serve Texas customers or utilize state resources.
Texas provides both explicit guidance on activities that do not require foreign registration and general principles for determining when registration is necessary. The state uses a comprehensive approach that examines the totality of business activities rather than relying on single factors.
Activities that do not require foreign registration in Texas:
These exemptions serve as safe harbors, meaning that engaging in these activities alone will not trigger registration requirements.
However, when combined with other business activities or conducted as part of regular operations, they may contribute to a finding that the entity is transacting business in Texas.
Specific Texas physical presence activities that require registration include:
Texas does not provide specific day-count thresholds for temporary presence, requiring case-by-case analysis of the duration, frequency, and purpose of activities.
Regular client visits, equipment servicing, or project management activities that extend beyond isolated transactions typically trigger registration requirements.
Texas requires foreign entities to register if they are “transacting business” in the state, but does not define this with specific revenue thresholds or codified economic standards.
The determination is based on a case-by-case analysis without a formal list of subjective factors; however, legal advisors often consider the nature and extent of Texas business activities when assessing registration obligations.
While registration requirements don't use bright-line revenue tests, Texas does impose separate tax nexus through economic activity standards. For franchise tax purposes, entities with annualized total revenue of $2,470,000 or more during a federal income tax accounting period are subject to Texas franchise tax obligations, which operate independently from registration requirements.
Texas has issued specific guidance for digital economy activities, enacting laws that regulate areas like artificial intelligence and app marketplaces, so SaaS providers, e-commerce businesses, and remote service companies must comply with both traditional and new, sector-specific regulations. Key considerations include:
Once your business activities approach Texas's "doing business" threshold, you should register as a foreign entity before conducting substantial operations.
Texas does not provide a specific grace period, though the state typically examines the date when regular business activities commenced rather than the first isolated transaction. When in doubt, Texas authorities recommend registering proactively to avoid enforcement actions and penalty accumulation.
Foreign entities operating without required registration in Texas face immediate and severe consequences:
These penalties accumulate on an annual basis from the date the entity should have registered, making prompt compliance essential to limit financial exposure and operational disruption.
