How to Register a Foreign LLC

Learn how to register a foreign LLC with a Certificate of Authority, foreign qualification fees, and the registered agent and tax rules for each state.

What a foreign LLC is

A foreign LLC is not an LLC from another country. It is an LLC doing business in a state other than the one where it was formed. If you formed your LLC in Delaware but open an office in Texas, your LLC is foreign in Texas. Learning how to register a foreign LLC means filing for foreign qualification in every state where you have a real presence. The process is similar to forming a new LLC, but the paperwork is shorter and the fees are lower, usually $100 to $500 per state.

When you must register in another state

You must register as foreign when you have a physical presence or significant activity in another state. Common triggers include an office, employees, or a warehouse. Owning property, having a bank account, or meeting clients there can also count. Merely selling online to customers in a state usually does not require registration, though it may create sales tax duties. Each state defines doing business differently, so check the rules before you assume you are exempt.

Step 1: Get a Certificate of Authority

The main document is called a Certificate of Authority, a Certificate of Registration, or a Statement of Foreign Qualification, depending on the state. You file it with the target state's Secretary of State. The form asks for your LLC's name, its home state, its formation date, and the address of its principal office. You also name a registered agent in that state. Fees range from about $100 to $500, and most states process the filing within a few business days online.

Step 2: Appoint a registered agent in that state

Every state where you qualify requires a registered agent with a physical street address in that state. The agent accepts legal documents and official mail for your LLC. You cannot use your home-state agent for another state, because the agent must be located where you are qualifying. Many owners use a national registered agent service that covers multiple states. See our registered agent page for how to choose one, and our registered agent guide for the details.

Step 3: Pay fees and file annual reports

Foreign qualification is not a one-time cost. Most states require an annual report or biennial report from foreign LLCs, with fees that range from $0 to $800 depending on the state. California charges foreign LLCs the same $800 annual franchise tax it charges domestic ones. Missing a report can lead to revocation of your Certificate of Authority, which means you lose the right to do business there. Our annual report guide lists the deadlines.

State taxes for foreign LLCs

Registering as foreign does not automatically mean you pay income tax in that state. You owe tax only on income connected to that state, which is called nexus. Many states use a formula based on your sales, payroll, and property in the state. You may also owe franchise tax, gross receipts tax, or sales tax. A state where you only qualify but do no business may still charge an annual fee. A tax professional can tell you exactly what you owe in each state.

What happens if you skip foreign registration

Operating in a state without a Certificate of Authority is risky. The state can fine you, block you from filing lawsuits there, and charge you for every year you operated without registering. You may also be unable to enforce contracts in that state's courts. Some states let you register late and pay back fees, but the penalties add up. If you are expanding, register before you open the door. For the home-state side of your business, see our start an LLC guide.
