An LLC formed in Delaware, Nevada, Wyoming, or any other state that operates in California has to register as a foreign LLC with the California Secretary of State and pay California taxes. The 'form somewhere else to avoid California' workaround almost never works. Here is what triggers the requirement, how registration works, and what happens if you skip it.

A common pattern: a California-based small business owner forms an LLC in Delaware, Nevada, Wyoming, or another state — usually based on advice that those states have better laws, lower taxes, or stronger asset protection. The LLC operates in California, the owner lives in California, the customers are in California, and the bank account is in California. But the LLC was formed somewhere else.

This pattern almost always ends in the same place:the LLC has to register as a foreign LLC in California, pay California’s $800 minimum tax, and follow California’s rules— while still paying for whatever the home state requires. The “form elsewhere to escape California” strategy works for almost nobody, and the people who get talked into it usually pay more than they would have paid by forming in California in the first place.

This article is plain-English orientation on what makes a foreign LLC subject to California registration, how the registration process works, the costs and ongoing obligations, and the situations where forming out-of-state actually does (and does not) make sense. Not legal advice for your specific situation.

What “foreign LLC” actually means

In LLC terminology, “foreign” does not mean international. It meansformed in a different state. A Delaware LLC operating in California is a “foreign LLC” from California’s perspective. A California LLC operating in Texas is a “foreign LLC” from Texas’s perspective. The terminology is about the relationship between the LLC’s home state and the state where the LLC is doing business.

California requires every “foreign” LLC that does business in California to register with the California Secretary of State as a foreign LLC. The registration creates a parallel California compliance obligation alongside the LLC’s home-state obligations.

The legal authority is California Corporations Code §17708.02, which requires foreign LLCs to register before transacting intrastate business in California, and §17708.07, which spells out the consequences of failing to register.

What “doing business” in California actually means

The threshold for “doing business” — the condition that triggers the registration requirement — is broad. California Revenue and Taxation Code §23101 defines “doing business” for tax purposes, and the FTB applies it expansively. Courts and the FTB have found “doing business” in California in scenarios including:

The LLC has a California office, employee, or agent
The LLC has California-based members or managers actively running the business from California
The LLC owns or leases real property in California
The LLC has California customers from whom it derives substantial revenue
The LLC’s California-source revenue exceeds specific thresholds (currently around $711,538 for 2024, adjusted annually) — under §23101(b), an LLC with more than this much California-source revenue is automatically “doing business” in California even if no other connection exists
The LLC’s California payroll exceeds specific thresholds (around $71,154 for 2024)
The LLC’s California real property and tangible personal property exceeds specific thresholds (around $71,154 for 2024)

The numerical thresholds get the most attention, but the bigger trigger for most California-based small businesses is simpler:if you live in California and run your LLC from California, the LLC is doing business in California, regardless of where it was formed.

What “doing business” does not include

A few activities that are explicitlynot“doing business” in California:

Maintaining a bank account in California (under §23101(d) and similar safe harbors)
Holding meetings of members or managers in California
Maintaining offices for the LLC’s own internal records in California
Defending or settling lawsuits in California
Selling through independent contractors located in California (in some circumstances)

These are limited safe harbors. They do not cover the typical pattern of “California resident running a California-operating business through an out-of-state LLC.”

How registration actually works

If a foreign LLC needs to register in California, the process is:

Step 1: Register with the California Secretary of State.The foreign LLC files an Application to Register a Foreign Limited Liability Company (Form LLC-5) with the Secretary of State. The filing includes the LLC’s home-state name, jurisdiction of formation, the date of formation, the principal office address, the LLC’s California agent for service of process, and a certificate of good standing from the home state. The current filing fee is $70.

Step 2: Initial Statement of Information.Within 90 days of registration, the foreign LLC files a Statement of Information (Form LLC-12) — the same form California LLCs file. The fee is $20. (SeeCalifornia Statement of Informationfor what this filing covers.) Biennial renewals are required after the initial filing.

Step 3: Pay the $800 California minimum franchise tax.The foreign LLC owes California’s minimum tax for any year it is doing business in California. (SeeThe $800 California LLC Taxfor the underlying rule.) Payment is via FTB Form 3522. The first payment is due the 15th day of the 4th month after the LLC begins doing business in California (or after registration, whichever comes first).

Step 4: File California tax returns.The foreign LLC files California Form 568 annually for as long as it does business in California. The form reports California-source income, applies any income-based fee under RTC §17942 if California income exceeds $250,000, and confirms the $800 minimum.

Step 5: Maintain home-state compliance.The LLC continues to comply with the home state’s rules — annual reports, taxes, registered agent, etc. The home-state obligations do not go away just because the LLC is also registered in California.

The result: a foreign LLC operating in California pays California’s costs (registration, $800 minimum, Statement of Information, possibly income-based fee)on top ofthe home state’s costs. Not instead of.

What happens if you do not register

The consequences of operating an unregistered foreign LLC in California are real and can be significant:

Cannot maintain lawsuits.California Corporations Code §17708.07 says that a foreign LLC that should have registered but did not cannot maintain any action or proceeding in California courts until it registers and pays back fees and penalties. This is a meaningful real-world problem if the LLC ever needs to sue a customer, enforce a contract, or defend itself in court.

Penalties.California can assess penalties for the period of unregistered operation. The penalties accumulate — the longer the LLC operated without registering, the more it owes. The FTB also assesses back $800 minimum taxes for each year the LLC was doing business in California.

Personal liability for some people.California can impose personal liability on the persons who knew the LLC was operating in California without registering — managers, officers, and authorized agents who carried on business knowing the LLC was unregistered. This is one of the few situations where LLC structure does not protect the people running the business.

No bar against being sued.Unregistered status does not protect the LLC from being sued. The LLC can be sued, served through the California Secretary of State, and held liable on California court judgments — it just cannot file its own lawsuits or counterclaims until it registers.

Cumulative cost.When an LLC eventually does register after years of operating without doing so, the bill includes back $800 minimum taxes for each year, accumulated penalties, the income-based fee for any year California income was over the threshold, late filing penalties for the missed Statements of Information, and registration fees. The total is often several thousand dollars or more — for a problem that started by skipping a $70 registration fee.

When forming out-of-state actually makes sense

A few situations where forming in another state genuinely fits the business:

The LLC actually operates in the other state.If the LLC’s primary operations, employees, customers, and physical presence are in Nevada, then forming in Nevada is appropriate. California does not enter the picture.

Multi-state operations with a thoughtful structure.A real estate company that holds property in multiple states sometimes has a business reason for organizing some entities in particular states based on the local rules for that state’s property. This is a real, situation-specific structure, not a generic “form in Nevada to avoid California” play.

Specific industries where forum law matters.A few industries (some kinds of investment funds, some intellectual property structures) have business reasons for using a Delaware LLC or limited partnership. These are sophisticated structures with specific reasons, not blanket strategies.

Asset protection structures with specific use cases.Some out-of-state structures, particularly involving Wyoming or Nevada, are sometimes used for specific asset-protection purposes. These have real but narrow applications, and they only work when the LLC’s California connections are minimal.

For most California-based small businesses — solopreneurs, consultants, service businesses, real estate investors holding California property — none of these situations apply. Forming in California is the right answer.

When forming out-of-state does not make sense

The most common situations where the “form out-of-state” strategy fails:

California resident running a California-operating business.The LLC will be doing business in California regardless of where it was formed. Out-of-state formation just adds a second compliance layer.

Real estate investor holding California real property.The LLC is doing business in California by owning California real estate. Foreign LLC registration is required. There is essentially no asset-protection benefit that is unique to out-of-state LLCs holding California property — California’s law applies to the property regardless of where the LLC was formed.

E-commerce business shipping to California customers.If California customers generate substantial revenue or the business has any California presence (office, employee, contractor), foreign LLC registration is likely required.

“My friend’s CPA said Wyoming is better for taxes.”Wyoming has no state income tax, but neither does California’s $800 minimum tax exempt out-of-state LLCs operating in California. A California-operating Wyoming LLC pays Wyoming registration fees, California’s $800 minimum, and any California income-based fees. The Wyoming “tax savings” do not apply to California operations.

The pattern: for businesses with California operations, the home-state rules of any other state do not displace California’s rules for the California portion of the business.

What “registered agent” means and why it matters

When a foreign LLC registers in California, it has to designate a California agent for service of process. This is the person or company authorized to receive legal documents on the LLC’s behalf within California. The agent has to have a physical address in California (a P.O. Box does not work).

Foreign LLC owners who do not live in California typically use a registered agent service rather than naming themselves or a friend. The fee is usually $100–$300 per year.

A foreign LLC that lets its registered agent designation go stale (the agent moves, the agent retires, the agent stops receiving the LLC’s mail) can be suspended by the Secretary of State, with the same consequences as any other suspended LLC. Keeping the registered agent current is part of ongoing compliance.

Common questions

My LLC is in Delaware but I live in California — does it have to register here?If the LLC does business in California (which is broad — see above), yes. For most California-resident owners running California-operating businesses, the answer is yes.

How much does it cost to register a foreign LLC in California per year?Registration fee is one-time ($70). Annual costs are $800 minimum tax to the FTB, biennial $20 Statement of Information ($10/year average), plus registered agent fees ($100–$300/year), plus the cost of California tax-return preparation. Plus whatever the home state requires.

My CPA says I should form in Wyoming for tax savings. Should I?If you are a California resident operating in California, no. California’s $800 minimum and California taxes apply regardless of where the LLC was formed. The “Wyoming tax savings” do not apply to your California operations. Your CPA can model the actual tax effect — usually the comparison ends with “form in California, save the duplicate compliance cost.”

Can I form in Wyoming for asset protection without registering in California?If the LLC actually does business in California, you have to register. Operating an unregistered foreign LLC in California is the path that creates the worst exposure — registration penalties, lost-suit-rights problems, and personal liability for the people running the LLC. The asset protection benefit (which is often overstated to begin with) is not worth the unregistered-operation risk.

What if I am moving to California from another state and have an existing LLC?You probably need to register as a foreign LLC in California once you start operating from California. The LLC can stay formed in the home state if there is a reason; otherwise, some owners choose to convert the LLC to a California LLC through a domestication or merger process. Worth a conversation with an attorney to pick the cleanest path.

Does my LLC’s name have to be available in California to register?Yes. If another California entity already uses the same name, the foreign LLC has to either change its name (in the home state, which can be expensive) or register under a “fictitious” name in California. The Secretary of State checks name availability as part of the registration process.

Can I dissolve the foreign LLC and form a new California LLC instead?You can. For California-resident owners running California-operating businesses, this is often the cleanest answer — dissolve the out-of-state LLC, form a California LLC, transfer assets and contracts to the new entity. There are tax and operational considerations, so worth running through with an attorney and CPA before pulling the trigger.

My LLC was formed in Nevada three years ago and I never registered in California. What do I do?Get current. The path is: register the foreign LLC, file back Statements of Information, pay the back $800 minimums for each year, file back California tax returns, pay accumulated penalties. The FTB and Secretary of State both have processes for catching up. The cost of catching up is meaningful but is the only way to clean up the situation.
