How to Register a Foreign LLC in Texas

Already have an LLC in another state but want to do business in Texas? To legally operate an out-of-state (or international) LLC in Texas, you need to register it as a foreign LLC in Texas. This process is also called obtaining a Certificate of Authority or foreign qualification. It allows your existing LLC to transact business in Texas without forming a new entity. In this guide, we'll walk through the steps to register a foreign LLC in Texas, the costs involved, and tips to ensure you stay compliant.

What Is a "Foreign LLC" in Texas?

In this context, "foreign" doesn't mean overseas – it refers to any LLC formed in a jurisdiction outside Texas (another state or country). For example, if you created an LLC in California or Delaware and now want to open an office or regularly do business in Texas, Texas considers that LLC a foreign entity. Texas law requires foreign entities "transacting business" in the state to register with the Texas Secretary of State.

Some common activities that typically constitute doing business in Texas include:

  • Having an office, store, or warehouse in Texas.
  • Having employees or representatives working in Texas.
  • Regularly soliciting business in Texas (more than just occasional sales).
  • Owning income-producing real estate in Texas.

If you're unsure whether your activities trigger the need to register, Texas statutes list certain activities that do not count as transacting business (for example, merely holding a bank account in Texas or selling through independent contractors). When in doubt, it's safest to register. Operating in Texas without registering can lead to penalties and loss of certain legal rights (like the ability to sue in Texas courts until registration is done).

Step 1: Choose a Registered Agent in Texas

Just like domestic Texas LLCs, a foreign LLC must appoint a Texas registered agent with a physical address in Texas. This agent will receive your LLC’s official legal documents and state communications. You can use a professional registered agent service or an individual (who is a Texas resident and available during business hours). If your company already has a Texas office, an employee could serve in this role, but many foreign LLCs opt for a service for reliability.

Make sure you have your registered agent’s name and Texas address ready, as you'll need to list it on the application.

Step 2: Check Name Availability and Consider an Assumed Name

Your LLC’s legal name from its home state will be listed on the Texas registration. Texas will not allow two different companies to register with the same name. So if your LLC’s name is already taken by another Texas business, you'll need to come up with an alternate name (often called a fictitious or assumed name) for use in Texas. You can search the Texas business name database via SOSDirect to check availability.

If you must use a different name in Texas, you will indicate that on the registration application and likely need to file an Assumed Name Certificate for that name as well (to formally declare the DBA in Texas). The assumed name filing (Form 503) with Texas costs $25 and also requires county-level filing similar to what we described for DBAs earlier.

Step 3: Complete the Application for Registration (Form 304)

Texas's form to register a foreign LLC is Form 304 - Application for Registration of a Foreign Limited Liability Company. You can find this form on the Texas Secretary of State website or file electronically via SOSDirect for faster processing. Here's the information you'll need to provide:

  • LLC Details: The legal name of your LLC as registered in its home state, and the state or country of formation.
  • Alternate Name (if needed): If your name isn't available in Texas or doesn't meet Texas naming rules (Texas requires LLC names to include "LLC" or similar, for instance), you'll list the name you're going to use in Texas.
  • Date of Formation and Duration: The original formation date of your LLC and how long it will last (perpetual or a set term).
  • Business Purpose: Texas may ask for a short description of the business activities or a general statement that the LLC is authorized to do any lawful business.
  • Principal Office Address: Your LLC’s main office address (usually in its home state).
  • Texas Registered Agent: The name and Texas street address of the agent (as selected in Step 1).
  • Governing Persons: Texas requires naming the LLC's managers or members (whoever manages the LLC). You'll list at least one person (could be individuals or entities if an entity member/manager).
  • Federal Employer ID (EIN): There's a field for EIN, if available.
  • Certificate of Good Standing: Texas may require a certificate of existence/good standing from your LLC’s home state, dated within 90 days. This document (obtained from your home state's Secretary of State or similar authority) proves your LLC is active and in good standing back home. While not explicitly required to attach in all cases, it's commonly requested, so be prepared to provide it if asked or to avoid delays.
  • Signature: An authorized person of the LLC must sign the form (could be a member, manager, or an authorized officer).

If filing by mail, prepare one signed original of Form 304 (and one copy, as recommended) and any necessary attachments (like the certificate of good standing). If filing online via SOSDirect, you'll input all information digitally and upload any documents as needed.

Step 4: Pay the Filing Fee

The state filing fee to register a foreign LLC in Texas is $750. This is a one-time fee at the time of registration (Texas foreign filings are relatively pricey). If you file online and pay by credit card, note there is a small processing fee (around 2.7%, which on $750 is about $20).

Texas does offer an expedited processing option for formation filings (for domestic filings it's $25 extra). However, for foreign registrations, online filing is typically processed in 2-3 business days, which is fairly quick. If you need even faster turnaround, consult the Secretary of State's office or a service company about walk-in expedited filing.

Be sure to remit the exact fee. If mailing, include a check or money order payable to "Texas Secretary of State."

Step 5: Receive Your Certificate of Registration

Once Texas approves your application, your LLC will be officially registered to do business in Texas. The state will issue a Certificate of Registration (basically Texas's equivalent of a certificate of authority). If you file online, you'll likely get an email notification and be able to download the certificate. If by mail, it'll be mailed to the address you provided for correspondence.

When you have this certificate:

  • Keep it with your company records. It’s proof that your LLC is authorized in Texas.
  • You can now legally conduct business in Texas. This means you can open offices, sign contracts, and generally operate, just as a Texas-formed business could.
  • You might need to provide a copy of this Texas registration when doing certain transactions, like leasing property or opening business bank accounts in Texas, to show you're properly registered in the state.

Step 6: Post-Registration Requirements

Registering your foreign LLC is just the first step. After that, make sure to attend to these ongoing obligations:

  • Texas Franchise Tax & Annual Information Report: Once registered, your LLC is subject to Texas franchise tax. Every LLC in Texas (foreign or domestic) must file an annual franchise tax report and public information report (PIR) by May 15 each year. If your LLC's revenue is below the no-tax-due threshold, you won't owe tax but still must file a no-tax-due report. If above, you'll calculate tax (Texas uses a margin calculation). The Texas Comptroller's office handles these filings (you'll want to register for a franchise tax account with the Comptroller after you get your certificate of registration).
  • Registered Agent Maintenance: If your registered agent or office changes, Texas law requires you to update that with the Secretary of State by filing a change form and paying a small fee ($15). Always maintain a valid agent; if the state or a plaintiff cannot reach you because your agent info is outdated, your business could fall out of good standing.
  • Assumed Name Renewals: If you were using an assumed name in Texas, remember that assumed name certificates expire after 10 years (or earlier, if you set a shorter term). Mark your calendar to renew or withdraw them as needed, especially if your LLC continues using the DBA.
  • Local Business Licenses/Permits: Foreign registration doesn't exempt you from any industry-specific licenses or local permits. Ensure that you obtain any necessary Texas licenses (e.g. sales tax permit from the Texas Comptroller for selling products, professional licenses for certain services, local county/City permits for a storefront, etc.) just as a local business would.
  • Foreign LLC as a "Texas Employer": If you'll have employees in Texas, register with the Texas Workforce Commission for unemployment tax and follow Texas employment regulations. Essentially, treat your foreign LLC like a local business for all operational compliance.

Consequences of Not Registering

What if you skip foreign registration? Aside from being out of compliance, Texas law imposes some penalties:

  • Monetary Penalties: Texas can charge your LLC for the years it did business without authority. In fact, the law sets a late registration fee equal to the registration fee for each year of delinquency. For example, if you operated for 2 years unregistered, they might assess an additional $1,500 (2 x $750) when you finally register.
  • Inability to Sue: Until registered, a foreign LLC can't maintain a lawsuit in Texas courts. That means if a contract dispute arises, you could be blocked from legal remedy until you rectify the registration (and pay any penalties). This can weaken your position in legal matters.
  • Contracts Could Be Voidable: While not automatically void, contracts made while not registered could be challenged. Once you register, that issue usually clears up, but it's a risk not worth taking.
  • Stop Business Orders: In some cases, the state could order your business to cease operations in Texas until compliance is met.

In short, if you plan to have a sustained presence or activity in Texas, it's crucial to go through this registration process.

Conclusion

Registering a foreign LLC in Texas is a straightforward process that ensures your out-of-state company can legally do business in the state. By filing the Application for Registration (Form 304) and paying the $750 fee, you'll secure your Certificate of Authority to operate in Texas. Once registered, remember to fulfill Texas's ongoing requirements just like any local business.

Going through this process might seem detailed, but it's a one-time setup that opens the door to the vast Texas market. If you need assistance or want to save time, consider getting professional help to prepare and file your foreign registration.
