California Foreign LLC Registration: Cost, Steps & Requirements (2026)

California is the world's fourth-largest economy and home to thousands of startups, tech companies and potential clients. So it's no surprise that founders with a Wyoming or Delaware LLC eventually ask: do I need to register in California too?

Sometimes the answer is yes. Often it's no. And getting it wrong in either direction is expensive, because California charges every registered LLC at least $800 a year, while operating there without registering can bring penalties of its own.

This guide explains California foreign LLC registration: when you need it, what it costs, and how to file.

What Is a Foreign LLC in California?

In U.S. business terms, "foreign" doesn't mean outside the U.S. It means formed in another state.

If you formed your LLC in Wyoming, Delaware or New Mexico and it's doing business in California, California treats it as a foreign LLC. Before operating there, it must register with the California Secretary of State. Your LLC stays formed in its home state; it simply gets permission to operate in California as well.

Do You Actually Need to Register?

This is the most important question in this guide. California considers an LLC to be doing business in the state if, among other things:

• It has employees or contractors working in California, even just one remote employee
• It has an office, warehouse or other property in California
• Its managers or members actively run the business from California
• Its sales into California exceed a yearly threshold set by the Franchise Tax Board, which is adjusted for inflation
• It regularly carries out business transactions inside California

What usually doesn't trigger registration on its own: having a few California clients, selling online to California customers below the sales threshold, or occasional one-off work for a California company while you're based in India.

Pro tip: Because California charges at least $800 every year once you register, don't register "just to be safe." Check your situation first, and if you're close to a threshold, speak with an advisor before filing.

How Much Does California Foreign LLC Registration Cost?

• Form LLC-5 (Application to Register): $70
• Initial Statement of Information (Form LLC-12): $20, due within 90 days of registering
• Annual franchise tax: at least $800 every year
• Extra LLC fee: applies once your California gross receipts reach $250,000
• Statement of Information renewal: $20 every two years

Yes, the $800 tax applies even if your LLC earns nothing in California that year. That single number is why California is one of the most expensive states to operate an LLC in, and why many founders form elsewhere and register in California only when they truly need to.

How to Register a Foreign LLC in California: Step by Step

Step 1: Confirm Your LLC Is in Good Standing at Home

California expects your LLC to be active and compliant in its home state. If you've missed an annual report or fee there, fix that first.

Step 2: Check Your LLC's Name

Your LLC's legal name must be available in California. If another business is already using it, you'll need to register under an alternate name for use in California.

Step 3: Appoint a California Registered Agent

You need a registered agent with a physical California address to receive legal and state mail. You can't use an Indian address or a P.O. box. Our guide on what an LLC registered agent does explains how to choose one.

Step 4: File Form LLC-5 on bizfile Online

File the Application to Register a Foreign LLC (Form LLC-5) through the Secretary of State's bizfile Online portal and pay the $70 fee. You'll provide your LLC's name, home state, formation date, registered agent and principal office address.

Step 5: File Your Statement of Information Within 90 Days

After approval, file Form LLC-12 within 90 days. It lists your LLC's addresses, managers or members, and registered agent. After that, you renew it every two years.

Step 6: Pay the $800 Franchise Tax

Pay the annual minimum tax to the California Franchise Tax Board (FTB). Your first payment is generally due by the 15th day of the 4th month after your LLC registers in California, then every year after that.

The Process Isn't the Same in Every State

California's $800 tax makes it unusual. Other states charge far less to register a foreign LLC and keep it active. For a comparison, see how the process works in our Florida foreign LLC registration guide.

What Happens If You Don't Register?

If your LLC is doing business in California without registering, you can face:

• Penalties from the state, which can add up daily over time
• Back franchise taxes, since the FTB can still require the $800 minimum for every year you were doing business there
• No access to California courts. An unregistered foreign LLC can't file a lawsuit in California, even to collect unpaid invoices, until it registers

Common mistake: Registering in California, then forgetting the yearly $800 payment. Unpaid franchise tax can lead to your LLC being suspended in California, which blocks it from operating there until you catch up on taxes, penalties and interest.

Don't Forget Your Federal Filings

California registration is a state matter. If your LLC is single-member and foreign-owned, you likely also need to file Form 5472 with a pro forma Form 1120 with the IRS every year, regardless of which states you're registered in.
