TEXAS BUSINESS LAW
Foreign Entity Registration in Texas: Who Must File
An out-of-state company must register with the Texas Secretary of State before “transacting business” in Texas — that’s the rule under Chapter 9 of the Texas Business Organizations Code. Registration means filing an application (Form 304 for an LLC, Form 301 for a corporation) and paying a $750 filing fee. Skip it, and the consequences stack up: you cannot maintain a lawsuit in Texas courts on Texas business, the state can collect late filing fees equal to the registration fee for every year you operated unregistered, and the entity is exposed to a civil penalty and even an injunction against doing business in the state.
The hard part is the first question: what counts as transacting business? Texas never defines it directly — instead, the statute lists what doesn’t count. Here is how to read that list, how to register, and what it costs to get it wrong.
What Counts as Transacting Business in Texas
Transacting business means carrying on regular, continuous business activity inside Texas — but the Business Organizations Code defines it only by exclusion. Section 9.251 lists activities that do not constitute transacting business; anything resembling ongoing operations beyond that list generally triggers registration. In practice, the common triggers are unambiguous:
- A physical location — an office, warehouse, store, or job site in Texas.
- Employees or agents working in Texas on more than an occasional basis.
- Owning and operating income-producing real estate, such as rental property (passively holding title, without more, is on the exempt list — operating rentals is not).
- Performing contracts in Texas as part of repeated, ordinary business.
Activities That Do and Don’t Require Registration
Section 9.251’s safe-harbor list includes sixteen activities. The most useful ones, set against their registration-triggering counterparts:
| You generally do NOT need to register if you only… | You generally DO need to register if you… |
|---|---|
| Defend or settle a lawsuit in Texas | Open an office, store, or warehouse in Texas |
| Hold member, shareholder, or board meetings in Texas | Hire employees who regularly work in Texas |
| Maintain a Texas bank account | Operate rental or other income-producing property |
| Sell through an independent contractor | Sell through your own Texas-based sales force |
| Make or collect loans, or take security interests in Texas property | Service customers from a Texas location on an ongoing basis |
| Own real or personal property in Texas, without more | Perform construction or service contracts in Texas repeatedly |
| Complete an isolated transaction finished within 30 days, not part of repeated similar transactions | Conduct repeated, similar transactions in the state |
| Transact business solely in interstate commerce | Run intrastate operations from inside Texas |
The list rewards careful reading. A Colorado LLC that merely holds title to Texas land is exempt; the moment it leases that land to tenants and manages it, most practitioners treat it as transacting business. Likewise, selling into Texas from out of state (interstate commerce) is exempt — fulfilling those sales from a Texas warehouse is not.
How to Register
Registration is a single filing with the Texas Secretary of State. For a foreign LLC, that’s Form 304 (Application for Registration of a Foreign Limited Liability Company); for a for-profit corporation, Form 301. Both carry a $750 filing fee as of 2026, and both can be filed online through SOSDirect (with a small card-processing surcharge) or by mail. You’ll need:
- A compliant name. If your legal name isn’t available in Texas, you register under an assumed name.
- A certificate of existence (good standing) from your home state, generally dated within 90 days.
- A Texas registered agent and registered office — a person or service with a physical Texas address available during business hours. The agent’s address is a statutory requirement distinct from your business address; see the difference between a registered agent address and a business address.
Nonprofit corporations and limited partnerships pay different (lower) fees, so check the SOS fee schedule for your entity type if you’re not an LLC or for-profit corporation.
What Happens If You Don’t Register
The Business Organizations Code attaches three distinct consequences to unregistered business, and they compound the longer you wait:
| Consequence | Statute | What it means |
|---|---|---|
| Closed courthouse doors | BOC § 9.051 | You cannot maintain a suit in Texas courts on a claim arising from your Texas business until you register. You can still defend yourself, and your contracts remain valid. |
| Late filing fees | BOC § 9.054 | If you transacted business more than 90 days before registering, the SOS collects a late fee equal to the registration fee for each full or partial calendar year of unregistered activity — $750 per year for an LLC or corporation. |
| Civil penalty and injunction | BOC §§ 9.052, 9.051(a) | The state can recover a civil penalty equal to all fees and taxes you would have owed had you registered on time, and the attorney general can seek a court order enjoining you from doing business in Texas. |
The late fee alone gets expensive fast: an LLC that operated in Texas unregistered since 2021 and registers in 2026 faces the $750 application fee plus roughly six years of late fees — over $5,000 before counting back franchise taxes.
Ongoing Obligations After You Register
Registration is the start of compliance, not the end of it. A registered foreign entity must maintain its Texas registered agent continuously and file an annual franchise tax report and Public Information Report with the Texas Comptroller, due May 15. For 2026 reports, no franchise tax is owed unless annualized Texas-apportioned revenue exceeds $2.65 million — but the reports are mandatory regardless, and missing them leads to forfeiture of your registration. Note that Texas also asserts franchise tax nexus over out-of-state entities with more than $500,000 in annual Texas receipts even if they never register, so the tax question and the registration question must be analyzed separately.
If you’re choosing between expanding into Texas as a foreign entity or forming a new Texas entity outright, the answer depends on your structure and home state — our comparison of forming in Texas versus Delaware walks through that decision.
Frequently Asked Questions
How much does it cost to register a foreign LLC in Texas?
$750, filed with the Texas Secretary of State on Form 304. Filing online through SOSDirect adds a small credit card processing fee.
Is there a grace period before I have to register?
Effectively, 90 days. Late filing fees only apply if you transacted business in Texas for more than 90 days before registering — but the duty to register exists from the moment you begin transacting business.
Can an unregistered foreign entity defend a lawsuit in Texas?
Yes. The penalty in Section 9.051 only bars maintaining an action — filing suit as plaintiff on Texas business. You can always defend, and failure to register doesn’t void your contracts.
Do I need to register just because I have Texas customers?
Not necessarily. Selling into Texas purely through interstate commerce, or through independent contractors, sits on the Section 9.251 exempt list. Registration is triggered by in-state operations — offices, employees, property management, repeated in-state performance.
If you’re unsure whether your Texas activity crosses the line — or you’ve already crossed it and need to fix it cleanly — Reidel Law Firm handles foreign entity registrations and Texas business compliance on transparent flat fees, so a back-registration doesn’t come with an open-ended bill.
