Forming an LLC in Delaware, Nevada, or another state does not automatically keep your business outside California’s registration and tax rules. If you operate from California, hire people here, or expand into the state, your LLC may have additional obligations. This guide explains when an out of state LLC doing business in California may need to register, how registration differs from tax compliance, and what to review before starting operations.
What California means by a foreign LLC
California calls an LLC formed under another state’s laws a “foreign” LLC. The term does not necessarily mean the company operates internationally. A Nevada LLC owned by someone living in California is a foreign LLC for California registration purposes.
Registering a foreign LLC generally allows the existing company to conduct business in California without creating a separate California entity. The LLC remains organized under its original state’s laws, and it must continue meeting that state’s requirements. California registration adds another layer of compliance; it does not replace the original formation.
For California businesses, the practical question is not simply where the formation documents were filed. It is where the company operates and what activities it conducts. A review of your business formation and registration requirements can help determine whether an out-of-state structure still fits your operations.
When is an out of state LLC doing business in California?
California Corporations Code §§ 17708.02 and 17708.07 govern foreign-LLC registration. A foreign LLC transacting intrastate business in California must obtain a certificate of registration. Whether registration is required depends on the company’s actual activities, not just its mailing address or formation state.
Facts that warrant closer review include:
- Maintaining an office, store, warehouse, or other operating location in California.
- Regularly providing services within California.
- Employing people who perform business operations in the state.
- Conducting recurring local transactions rather than an occasional interstate transaction.
Not every California connection requires registration. Corporations Code § 17708.03 excludes certain activities from “transacting intrastate business,” including maintaining bank accounts, conducting internal company affairs, selling through independent contractors, and transacting business in interstate commerce. It also excludes an isolated transaction completed within 180 days that is not part of a course of repeated transactions of a like nature. Other statutory exclusions may also apply.
These exclusions require attention to the facts. For example, having California customers does not automatically resolve the registration question. Taking orders accepted outside California may present a different situation from repeatedly performing services at customers’ California locations. A founder managing daily operations from a California home should not assume an out-of-state address removes the registration requirement.
Registration and California taxes are separate questions
The Secretary of State’s registration rules and the Franchise Tax Board’s tax rules use different standards. An activity excluded from the registration requirement may still create California tax obligations.
California Revenue and Taxation Code § 23101 defines “doing business” for tax purposes. Its rules include actively engaging in transactions for financial gain and being organized or commercially domiciled in California. For taxable years beginning on or after January 1, 2011, the rules also include California sales exceeding the lesser of an annually adjusted dollar threshold or 25% of total sales; California real or tangible personal property exceeding the lesser of an annually adjusted threshold or 25% of total such property; and California compensation exceeding the lesser of an annually adjusted threshold or 25% of total compensation. The statutory base amounts are $500,000 for sales and $50,000 each for property and compensation, but these are not the inflation-adjusted 2026 thresholds. Review the Franchise Tax Board’s adjusted figures for the relevant tax year.
Important tax issues include:
- Annual tax: An LLC subject to California’s LLC tax rules generally owes the $800 annual LLC tax for each taxable year if it is doing business in California or has California articles of organization or a certificate of registration, subject to statutory exceptions. Exceptions may include qualifying tax-exempt LLCs and certain LLCs owned by deployed members of the military, subject to specific conditions. The temporary first-taxable-year exemption applied only to taxable years beginning on or after January 1, 2021, and before January 1, 2024; it generally does not apply to a new 2026 registration.
- Additional LLC fee: An LLC subject to California’s LLC fee rules generally owes an annual fee when total income from all sources derived from or attributable to California is $250,000 or more. The fee is $900 for income of $250,000 to less than $500,000; $2,500 for $500,000 to less than $1 million; $6,000 for $1 million to less than $5 million; and $11,790 for $5 million or more. This is not simply a tax on net profit; the statutory calculation matters.
- Return requirements: California returns may be required even when the company owes little or no income-based tax. LLCs that elect corporate tax treatment are subject to different tax and return rules.
- Other obligations: Employees, taxable sales, and local operations can create payroll, sales tax, or business-license requirements.
A CPA can evaluate tax exposure alongside an attorney’s registration analysis. Registering now does not erase liabilities from earlier years, and leaving the LLC unregistered does not prevent the state from assessing taxes.
How to register an out-of-state LLC
If registration is required, prepare the filing around the company’s existing records and intended California activities. A typical process includes:
- Confirm the company’s status. Obtain a certificate of existence, status, or good standing—or a similar record—from the formation jurisdiction. It must be issued within six months before submitting the California application.
- Check the business name. Confirm that the name meets California Corporations Code § 17701.08. If it does not, the foreign LLC must adopt a compliant alternate name under § 17708.05 before obtaining its certificate of registration. It must transact intrastate business under that name unless otherwise authorized by applicable fictitious- or assumed-name law.
- Designate a California agent for service of process. This person or registered corporate agent receives legal papers for the company.
- Submit the registration application. File Form LLC-5 (Application to Register a Foreign Limited Liability Company) with the California Secretary of State and pay the $70 filing fee.
- Calendar ongoing obligations. File the initial Statement of Information within 90 days and subsequent statements every two years. Separately track tax filings, payments, permits, and formation-state deadlines.
Registration is not a substitute for professional licensing or industry-specific approval. Confirm those requirements before beginning regulated activities.
What happens if you operate without registering?
An unregistered foreign LLC that is transacting intrastate business generally cannot maintain an action in a California court until it registers. Corporations Code § 17708.07 addresses this restriction, while also providing that nonregistration does not invalidate the LLC’s contracts or prevent it from defending an action.
That distinction matters when a customer stops paying or a contract dispute arises. The company may need to correct its registration before pursuing its claim. Separate penalties, taxes, and filing obligations may also apply.
Before expanding, document when California activities began, where work occurs, and who performs it. If operations have already started, review those facts promptly rather than assuming a new filing resolves every past obligation.
