A foreign LLC is a limited liability company doing business in a state other than the one where it was formed. The SBA explains that your formation state treats the LLC as domestic and every other state treats it as foreign, so if your LLC is active in another state you usually need to file for foreign qualification there, often called a Certificate of Authority.
The word foreign here has nothing to do with another country. A Delaware LLC opening an office in Texas is a foreign LLC in Texas. This page uses the SBA's guide to registering a business and the Texas Secretary of State's foreign entity FAQs, read in October 2026, with Texas as the worked example because its rules and fees are published in detail.
Domestic versus foreign at a glance
| Domestic LLC | Foreign LLC | |
|---|---|---|
| Where | The state where you filed your articles of organization | Any other state where the LLC does business |
| Filing | Articles of organization | Foreign qualification, often a Certificate of Authority |
| Ongoing costs | Taxes and annual report fees in that state | Taxes and annual report fees in that state too |
| Registered agent | Needed in the formation state | Needed in each state where you qualify |
The SBA points out that foreign qualified businesses typically pay taxes and annual report fees both in their state of formation and in each state where they're foreign qualified. That double cost is the main reason not to form in a far-off state you don't operate in.
When you have to register
The trigger is usually doing business, or transacting business, in the state. Texas is a good example of how vague that can be. The Texas Secretary of State says its statutes don't define transacting business, although section 9.251 of the Business Organizations Code lists 16 activities that don't count. Generally, a foreign entity is transacting business in Texas if it has an office or an employee there, or is otherwise pursuing its purposes there.
Having staff, an office or a warehouse in a state is the clearest signal. If you only sell to customers there online, check that state's own list before deciding.
How to register a foreign LLC
- Get a Certificate of Good Standing from your formation state, because many states ask for one.
- Appoint a registered agent with an address in the new state.
- File the state's foreign registration form, called an application for registration in Texas and a Certificate of Authority in many states.
- Pay the state's filing fee.
- Diary the new state's annual report and tax deadlines alongside your home state's.
My certificate of good standing guide explains how to order one, and my registered agent guide covers who can act as your agent.
What it costs in Texas
Fees vary by state and business structure, so check each state's own fee schedule. In Texas, the Secretary of State's FAQ says the registration fee is $750 for most entities and $25 for nonprofit corporations and cooperative associations, as of October 2026. Applications can be filed online through SOSPortal, which runs 24 hours a day.
The penalty for not registering
Here's the part that turns a small filing into an expensive one. If a foreign entity transacts business in Texas without registering, the Texas Secretary of State lists four consequences.
- The entity can't maintain an action, suit or proceeding in a Texas court until it registers.
- The attorney general can stop the entity from transacting business in Texas.
- The entity owes a civil penalty equal to all fees and taxes it would have paid if it had registered on time.
- If it has done business in Texas for more than 90 days, a late filing fee equal to the registration fee applies for each calendar year or part year of delinquency.
So an LLC that waits several years to register can owe the registration fee once for every year it was late, on top of the fee itself. Not being able to sue a customer over an unpaid invoice can be the bigger problem.
After you register
Registration isn't a one-off. In Texas a foreign entity must amend its registration on or before the 91st day after certain changes, such as a change of name or of the business stated in its application. Foreign entities subject to franchise tax file an annual franchise tax report with the Texas Comptroller, which my Texas franchise tax guide explains. To leave, a foreign entity files a withdrawal on Form 608, and for most entities it must include a Certificate of Account Status from the Comptroller.
Foreign LLC and foreign-owned LLC are different
People mix these up. A foreign LLC is about states: your LLC operating outside its formation state. A foreign-owned LLC is about ownership by a non-US person, which brings separate federal filing rules covered in my Form 5472 guide. Texas also requires non-US corporations, LLCs, LPs and financial institutions to register with the Secretary of State before transacting business there, and they're subject to state franchise tax.

My verdict
If your LLC has people, premises or regular operations in another state, plan on registering as a foreign LLC there. Do it before you start, not after a customer dispute, because the cost of registering late is far higher than the fee. And if you're only forming in another state for its reputation, count the second set of annual fees first.
