Texas: Foreign LLC Registration and Qualification Requirements

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.
