How to Start an LLC in California: Steps, Costs, and Timeline

To start a California LLC, choose a compliant name, identify an agent for service of process, prepare the required business addresses, and file Articles of Organization through the California Secretary of State’s bizfile Online system. The online filing fee for a domestic California LLC is $70. After registration, file the initial Statement of Information within 90 days and address California’s tax, licensing, recordkeeping, and ongoing filing obligations.

The state filing process is only one part of the launch. A practical formation plan should account for the $20 online Statement of Information fee, California’s generally applicable $800 annual LLC tax, possible income-based fees, and any permits tied to the business’s activity and location.

California LLC formation overview

An LLC is one possible structure for operating a California business. Before filing, compare its ownership, management, tax, and administrative implications with other structures. If a corporate structure may be more suitable, review this California corporation formation overview before committing to an LLC.

Formation begins with the Articles of Organization, but registration does not complete every post-formation task. The initial Statement of Information is a separate filing, and California tax obligations continue after the business is created. Licensing, zoning, and permit needs depend on what the business does and where it operates, so they should be researched separately rather than treated as part of the Articles filing.

Your initial budget should distinguish between formation charges and ongoing obligations. The Articles cost $70 when filed online, while the initial online Statement of Information costs $20. These amounts do not include the annual LLC tax, a potential income-based LLC fee, optional services, or activity-specific permits.

Information to prepare before filing

LLC Name

Select the LLC’s legal name before beginning the Articles. For domestic California Articles of Organization, the name must include an LLC identifier such as “LLC” or “L.L.C.” If the submitted name does not contain an identifier, the Secretary of State will add “LLC.”

Choose the legal name with future branding in mind. If the public-facing name will differ from the LLC’s legal name, a separate DBA filing may be relevant. A DBA does not replace LLC formation; it addresses use of a different business name. See the California DBA registration overview for that separate process.

Principal office address

Prepare the initial street address of the LLC’s principal office. Form LLC-1 requires this address, and a P.O. box cannot be used in the principal-office street-address field. Confirm the exact address before filing so that the LLC’s records are consistent from the start.

Agent for service of process

The Articles must identify an agent for service of process. The LLC must provide either an individual agent’s full name and California street address or the name of a registered corporate agent. Decide who will serve in that role before opening the online filing. Use information the agent has agreed can be submitted and can keep current.

Also settle the LLC’s basic management and ownership arrangements. An internal operating agreement can document decision-making authority, member responsibilities, financial arrangements, and procedures for ownership changes. Preparing those terms early can reduce uncertainty even though the agreement is separate from the online Articles filing.

Step-by-step California LLC process

1. Confirm that an LLC fits the business. Consider the owners, management structure, anticipated tax treatment, financing plans, and administrative workload. Where appropriate, consult legal or tax professionals about circumstances specific to the owners and business.
2. Choose the legal name. Use the intended legal name consistently and include an acceptable LLC identifier. Think separately about whether the company will operate under another public-facing name that could call for a DBA.
3. Gather the filing details. Prepare the principal-office street address, any additional mailing information requested in the filing, and the agent information. Review names and addresses carefully before submission.
4. File the Articles of Organization. Submit the domestic California LLC Articles through the Secretary of State’s bizfile Online system and pay the $70 online filing fee. Save the submission confirmation and retain the accepted formation document with the company’s permanent records.
5. Organize the LLC’s internal records. Document the owners’ arrangements, establish who may sign contracts or authorize payments, and create a reliable place for formation records, tax notices, agreements, and filing confirmations.
6. File the initial Statement of Information. The initial filing is due within 90 days after registration. The online fee is $20. After that, a Statement of Information is due every two years.
7. Address tax administration. California generally imposes an $800 annual tax on every LLC organized in the state or doing business there, even if the LLC is not conducting business, until it is canceled, subject to officially stated exceptions. Calendar the applicable payment date rather than assuming the formation payment covers this tax.
8. Check operational registrations. Review the business’s location, products, services, and sales activity for licensing, zoning, permit, and tax-registration needs. For example, a business making taxable sales may need to examine the California seller’s permit requirements. Those requirements are separate from LLC formation.

Costs and timeline

The known state charges at the beginning of the online process are $70 for the Articles of Organization and $20 for the initial online Statement of Information. Budget beyond those filing fees. California’s $800 annual LLC tax generally applies to California-organized LLCs and LLCs doing business in the state, subject to officially stated exceptions.

For the first year, the annual tax is due by the 15th day of the fourth month from the Secretary of State filing date. Subsequent payments are due by the 15th day of the fourth month of the taxable year. Mailed payments use FTB 3522, while online payment options are also available.

An LLC with more than $250,000 in California income must also pay an income-based fee. Depending on the applicable income bracket, that fee is $900, $2,500, $6,000, or $11,790. The estimated fee is due by the 15th day of the sixth month of the current tax year using FTB 3536.

Tax filing is distinct from paying the annual tax or estimated fee. An LLC doing business in California or registered with the Secretary of State must file Form 568 by its applicable original return due date. The exact deadline depends on the LLC’s tax classification, so tax dates should be determined for the particular LLC rather than copied from another business’s calendar.

There is no single guaranteed formation turnaround. As last updated July 31, 2026, the Secretary of State was reviewing online LLC formations received July 30 and in-person or mailed formations received July 28. Those dates show which submissions were under review; they are not guaranteed processing times. Check the state’s current processing status when planning a launch, and avoid making a contract, lease, or opening date depend on an assumed approval date.

Practical mistakes to avoid

• Treating the $70 filing as the complete startup cost. The separate Statement of Information fee, annual LLC tax, potential income-based fee, and business-specific permits can materially change the budget.
• Using a P.O. box in the principal-office street-address field. Prepare an eligible street address for that field before starting Form LLC-1.
• Providing incomplete agent information. Confirm whether the filing will name an individual with a California street address or a registered corporate agent, and enter the appropriate information for that choice.
• Missing the 90-day filing. Formation does not eliminate the need for the initial Statement of Information. Calendar it immediately after registration, along with the later two-year filing cycle.
• Assuming no activity means no annual tax. The $800 tax generally continues even when the LLC is not conducting business, until the entity is canceled, subject to stated exceptions.
• Confusing a DBA with an LLC. Registering or using another business name does not itself create the LLC. Keep legal formation and name-use filings conceptually separate.
• Relying on a quoted processing date as a promise. Processing-status dates report the submissions currently under review and do not guarantee when a new filing will be completed.

Next steps after registration

Once the Articles are accepted, save the filed document, submission receipt, and related correspondence. Complete the internal operating agreement, maintain clear ownership and management records, and determine what information a bank or other service provider will request. Evaluate whether the LLC needs an EIN based on its tax, payroll, banking, and operational circumstances.

Create a compliance calendar that includes the initial Statement of Information, the subsequent biennial filings, annual-tax dates, the applicable Form 568 deadline, and any estimated income-based fee date. Add renewal dates for local or activity-specific licenses after those obligations have been identified.

Finally, keep the company’s legal identity consistent. Use the LLC’s correct legal name on contracts and core records, document any authorized DBA separately, and update state records when relevant information changes. This turns formation from a one-time filing into an organized compliance process that is easier to manage as the business grows.
