How to Register a Foreign LLC in California (2026)
Formed your LLC in Delaware, Wyoming, or another state — but doing business in California? You’re required to register as a foreign LLC. Here’s exactly how, what it costs, and what happens if you don’t.

A “foreign LLC” in California doesn’t mean international — it means an LLC formed in any state other than California that does business in California. If your Wyoming LLC has an office in Los Angeles, or your Delaware LLC hires a California employee, or you personally live in California and operate your out-of-state LLC from home — you’re doing business in California and must register.
When Are You Required to Register as a Foreign LLC in California?
California requires foreign LLC registration if you are “transacting intrastate business” in California. The California Corporations Code defines this as “entering into repeated and successive transactions of its business in this state, other than interstate or foreign commerce.” In practice, you need to register if you:
- Have a physical office, store, or warehouse in California
- Have employees who work in California
- Regularly meet with California clients in person
- Own California real estate in the LLC’s name
- Have a California bank account in the LLC’s name
- Conduct significant ongoing California business (not just one-time transactions)
The gray area: One-time sales to California customers probably don’t trigger registration requirements. But if California is a regular, ongoing market for your business — even if you’re based elsewhere — you likely need to register. California takes this seriously and will pursue back taxes and penalties on foreign LLCs that should have registered but didn’t. When in doubt, consult a California business attorney.
Foreign LLC Registration: Step-by-Step
Step 1: Check Your LLC Name’s Availability in California
Your LLC’s name must be distinguishable from other California-registered businesses. Search at bizfile.sos.ca.gov. If your name is already taken by a California entity, you must adopt an assumed name (DBA) for use in California.
Step 2: Obtain a Certificate of Good Standing from Your Home State
California requires a Certificate of Good Standing (or Certificate of Status) issued by the Secretary of State of your home state, dated within 6 months. This proves your LLC is currently in good standing in its state of formation. Order this from your home state’s Secretary of State website — costs typically $5–$20.
Step 3: Appoint a California Registered Agent
You need a California registered agent with a physical California address. Corp Nation serves as your California registered agent as part of the $199/yr annual compliance plan.
Step 4: File the Application to Register
File Form LLC-5 (Application to Register a Foreign Limited Liability Company) with the California Secretary of State. The filing fee is $70. Attach your Certificate of Good Standing from your home state. File online at bizfile.sos.ca.gov or by mail.
Step 5: File Statement of Information
Within 90 days of your registration being approved, file a Statement of Information (Form LLC-12) with the California Secretary of State. The fee is $20. After that, file every two years.
Step 6: Register with the California FTB
Register your foreign LLC with the California Franchise Tax Board and begin paying the $800 annual franchise tax. You owe this from your first year of doing business in California — even before your Application to Register is approved.
Costs of Registering a Foreign LLC in California
| Cost | Amount | Notes |
|---|---|---|
| Application to Register (Form LLC-5) | $70 | One-time state fee |
| Certificate of Good Standing (home state) | $5–$25 | Order from your home state |
| California Annual Franchise Tax | $800/year | Mandatory, regardless of revenue |
| Statement of Information | $20 | Every 2 years |
| California Registered Agent | $199/yr (Corp Nation) | Required — must have CA address |
| Total Year 1 (approximate) | $1,100–$1,200 | Ongoing: $999+/yr |
Penalties for Failure to Register
California takes foreign LLC registration seriously. Penalties for doing business in California without registering include:
- $20–$20,000 fine plus all back taxes and fees owed from when you started doing business in California
- Inability to sue in California courts — you cannot bring a lawsuit to enforce a California contract if your LLC was not properly registered when the contract was entered into
- Personal liability risk — operating as an unregistered foreign LLC can expose members to personal liability for LLC debts incurred in California
Delaware LLC Doing Business in California: The Real Cost
This is the most common scenario: someone forms a Delaware LLC for its legal flexibility and investor-friendliness, then operates the business in California. What do they actually pay?
| Cost | Delaware LLC | Plus California Registration |
|---|---|---|
| Formation fee | $110 (Delaware) | + $70 CA = $180 total |
| Annual franchise tax | $300 (Delaware annual tax) | + $800 CA = $1,100/year |
| Registered agent | Needed in Delaware | + Needed in CA = two agents |
| Statement of Information | None in DE | $20 every 2 years in CA |
| Total first-year state costs | $410 | $1,110 — $700 more than a pure CA LLC |
The bottom line on Delaware + California: If you live and work in California, forming a Delaware LLC and registering as a foreign LLC in California costs you approximately $700–$800 MORE per year than just forming a California LLC directly. The Delaware LLC makes sense if you’re raising VC capital (investors require it) or have specific legal structure needs. For a California-based small business, just form in California and save the money.
