Foreign LLC Registration and Qualification Requirements in Texas

At a glance

Requirements one by one

Governing law and registration term

Chapter 9 of the Texas Business Organizations Code calls an out-of-state LLC a foreign filing entity and calls the filing an application for registration. Form 304 is the ordinary foreign-LLC application.

Registration under Chapter 9 does not replace a separate tax, employment, professional, or local filing required by another law.

Trigger and required timing

Under § 9.001, a foreign LLC must register “to transact business in this state” and keep the registration while it continues that business. The Code does not define the positive boundary with a universal office, employee, customer, or property test.

Instead, read the nonexclusive safe harbors first. If the actual activity is not resolved by §§ 9.251-9.252, whether it crosses the remaining boundary is fact-specific.

Statutory safe harbors

Under § 9.251, the safe harbors include proceedings and settlements, internal affairs and meetings, bank accounts, securities functions, voting acquired interests, independent-contractor sales, borrowing/lending and security interests, debt collection, interstate commerce, and a qualifying isolated transaction.

Texas adds detailed mortgage-servicing and nonoperating mineral-interest routes, owning Texas property “without more,” and acting as a governing person of a registered entity. Under § 9.252, this list is not exclusive.

The isolated transaction must be completed within 30 days and must not be part of repeated similar transactions. Both conditions matter.

Application contents and signer

Under § 9.004, the application requires the name and any compliant Texas name, entity type, formation jurisdiction and date, valid-existence certification, proposed purpose, first or intended Texas-business date, principal office, agent and office, governing persons, and Secretary-of-State fallback appointment. Form 304 also asks for the federal employer identification number or an unavailable selection.

An authorized person signs under § 4.001. Form 304 adds the registered-agent consent affirmation, false-filing warning, and penalty-of-perjury certification of signing authority.

Home-state evidence

Texas does not require an ordinary Form 304 applicant to attach a separate certificate of existence or good standing. Section 9.004(b)(5) instead requires the application to state that the entity validly exists, and item 5 has the authorized signer make that certification as of filing.

There is therefore no certificate-age window to calculate for this filing. A private checklist that demands a 30-, 60-, or 90-day home-state certificate is adding a document that the current statute and official form do not require.

Name, agent, and local address

If the home name does not comply with Chapter 5, the application states a compliant name for Texas use. Form 304 separately accommodates a missing LLC identifier or an unavailable home name.

Under § 5.201, the agent is a consenting Texas-resident individual or a consenting organization registered or authorized in Texas, other than the LLC being represented. The registered office is the same Texas street location as the agent's business office, where personal service can occur; it cannot be solely a mailbox or telephone-answering service.

Filing method, fee, and effective date

The Secretary's forms index offers Form 304 through SOSDirect and as a paper form; the form also supplies mail and fax submission information. Under § 4.152, the comparable application fee is $750, and § 4.154 applies it to LLCs.

The default effective date is filing under § 4.051. Form 304 also permits a specified delayed date or future event within the Chapter 4 rules, but the outside date cannot be later than day 90 after signing.

Unregistered consequences and cure

An unregistered foreign LLC cannot maintain a Texas action on a claim arising from its Texas business until it registers. It may defend, its contracts and acts are not invalid solely from the lapse, and an LLC member does not incur status-only liability under § 9.051.

The Attorney General may seek an injunction and recover the civil penalty in § 9.052: the fees and taxes that would have applied, plus associated penalties and interest. If the LLC transacts business unregistered for more than 90 days, § 9.054 permits a separate late filing fee equal to the $750 registration fee multiplied by each calendar year, with a partial year counted as a full year.

The Secretary becomes a service agent for an unregistered foreign filing entity under § 5.251. Service uses duplicate copies and the statutory fee, and the Secretary forwards a copy by certified mail to the latest address on file.

What trips people up

Texas has no attached status-certificate requirement for Form 304. The application contains its own current-valid-existence certification. Do not add a fictional 90-day evidence window.

The 90-day period is not permission to operate unregistered. Registration is required to transact business. The period controls when the Secretary may collect the separate late filing fee.

The late filing fee counts calendar years, not twelve-month blocks. A partial calendar year counts as a full one, so crossing January 1 can materially change the calculation.

Property ownership is qualified by “without more.” The statute protects ownership alone. Additional operating activity must be analyzed separately.

Common questions

Does one isolated Texas deal require registration? The express safe harbor applies if the deal is completed within 30 days and is not part of repeated similar transactions.

Can an unregistered LLC defend itself in court? Yes. The bar applies to maintaining its own Texas-business claim, while defense and contract validity are expressly preserved.

Can the foreign LLC name itself as registered agent? No. An organization agent must be someone other than the represented foreign filing entity.

Does later registration erase all past charges? No. It removes the stated registration condition for court access, but back fees, taxes, penalties, interest, and any calculated late filing fee remain separate.
