Single-Member LLC in California (2026)

Fact-checked by the LegalGlass editorial team against primary sources · Published Aug 6, 2026 · Last updated Aug 6, 2026

A California single-member LLC is formed by filing Articles of Organization (Form LLC-1) with the California Secretary of State for a $70 fee. It must pay an annual $800 franchise tax to the Franchise Tax Board (FTB), and if its total income from California sources is $250,000 or more, it will also owe an annual LLC fee based on gross receipts.

What is a Single-Member LLC in California?

A single-member LLC (SMLLC) in California is a limited liability company with only one owner, known as a member. Like all LLCs, it is a legal entity separate from its owner, providing limited liability protection. This means the owner's personal assets are generally shielded from the business's debts and liabilities. California law treats SMLLCs similarly to multi-member LLCs for formation and compliance purposes, but there are distinct tax implications.

The primary advantage of an SMLLC over a sole proprietorship is the limited liability protection. While a sole proprietorship is simple to form, it offers no legal separation between the owner and the business, leaving personal assets at risk. An SMLLC provides this protection while retaining the default tax simplicity of a sole proprietorship at the federal level.

Forming an SMLLC in California involves specific steps and ongoing obligations, particularly regarding state taxes and fees, which are more substantial than in many other states. This guide details the process and requirements for a California SMLLC, from formation to ongoing compliance and taxation.

Forming a California Single-Member LLC

The process for forming a single-member LLC in California is identical to forming any other LLC. It begins with filing Articles of Organization (Form LLC-1) with the California Secretary of State. This document officially creates the LLC.

1. Choose a Name: Select a name that includes an LLC designator (e.g., "LLC," "L.L.C.," "Limited Liability Company") and is distinguishable from existing entities on file with the California Secretary of State. You can check name availability through the Secretary of State's business search tool.
2. Appoint a Registered Agent: Every California LLC must continuously maintain a registered agent with a physical street address in California. The agent receives legal documents and official correspondence on behalf of the LLC. The agent can be an individual California resident or a qualified corporation.
3. File Articles of Organization (Form LLC-1): Complete and submit Form LLC-1 to the California Secretary of State. The filing fee is $70. This form requires the LLC's name, its registered agent's name and address, and a statement of purpose. You can file online, by mail, or in person.
4. Draft an Operating Agreement: Although not filed with the state, an operating agreement is crucial for an SMLLC. It defines the LLC's structure, the member's rights and responsibilities, management structure, and how the business will operate. For an SMLLC, it serves as a foundational document for internal governance and can be important for demonstrating the LLC's separate legal existence.
5. Obtain an EIN: A federal Employer Identification Number (EIN) is generally required for an SMLLC if it has employees, elects to be taxed as a corporation, or is required to file excise, employment, or alcohol, tobacco, and firearms taxes. Even if not strictly required by the IRS, most banks require an EIN to open a business bank account. You can obtain an EIN for free from the IRS.

Taxation of a California Single-Member LLC

The taxation of a California single-member LLC involves both federal and state considerations. By default, the IRS treats an SMLLC as a "disregarded entity" for federal income tax purposes. This means the LLC itself does not file a separate federal income tax return; instead, its income and expenses are reported on the owner's personal tax return, typically on Schedule C (Profit or Loss From Business) of Form 1040, as if it were a sole proprietorship.

California generally conforms to the federal classification of SMLLCs as disregarded entities for state income tax purposes. However, California imposes specific taxes and fees directly on LLCs, regardless of their federal tax classification:

• Annual LLC Franchise Tax: Every LLC doing business in California, including SMLLCs, must pay an annual franchise tax of $800 to the Franchise Tax Board (FTB). This tax is due by the 15th day of the 4th month of the LLC's taxable year (April 15 for calendar-year filers) and is paid until the LLC officially cancels.
• Annual LLC Fee (Gross Receipts Fee): If a California LLC's total income from California sources is $250,000 or more, it must pay an additional annual LLC fee based on its gross receipts. This fee ranges from $900 for gross receipts between $250,000 and $499,999, up to $11,790 for gross receipts of $5,000,000 or more. This fee is due by the 15th day of the 6th month of the taxable year (June 15 for calendar-year filers).

These state-level taxes and fees are significant and are a primary consideration for anyone forming an LLC in California. For more details on state business taxes, refer to California business tax.

EIN Requirements for a California SMLLC

While a single-member LLC is a disregarded entity for federal income tax purposes, it often still requires an Employer Identification Number (EIN) from the IRS. An EIN is a nine-digit number used to identify a business entity for tax purposes.

An SMLLC must obtain an EIN if it:

• Has employees.
• Elects to be taxed as a corporation (S-corp or C-corp).
• Is required to file excise, employment, or alcohol, tobacco, and firearms taxes.

Even if none of these conditions apply, most banks require an EIN to open a business bank account for an LLC. Therefore, it is highly recommended for virtually all California SMLLCs to obtain an EIN. The EIN application process is free and can be completed online through the IRS website.

Ongoing Compliance for a California SMLLC

Maintaining compliance for a California single-member LLC involves several ongoing obligations beyond the annual franchise tax and gross receipts fee:

• Statement of Information: All California LLCs must file a Statement of Information (Form LLC-12) with the Secretary of State within 90 days of filing the Articles of Organization, and biennially thereafter. The filing fee is $20. This form updates the state with current information about the LLC, including its registered agent and principal office address.
• Business Licenses and Permits: Depending on the industry and location, an SMLLC may need various federal, state, and local business licenses and permits. California does not have a single general business license, so it's essential to research requirements specific to the business activity and city/county of operation.
• Sales and Use Tax: If the SMLLC sells tangible personal property, it may need to register with the California Department of Tax and Fee Administration (CDTFA) to collect and remit sales and use tax.
• Record Keeping: Maintaining accurate financial records and corporate minutes (even for an SMLLC) is crucial for legal and tax compliance and to uphold the limited liability shield.

Failure to meet these compliance requirements can result in penalties, loss of good standing, or even administrative dissolution of the LLC by the state.

Dissolving a California Single-Member LLC

To properly close a California single-member LLC, the owner must follow specific dissolution procedures to avoid ongoing tax liabilities and potential legal issues. The process generally involves:

1. Winding Up Business Affairs: This includes paying all debts, collecting outstanding receivables, and distributing any remaining assets.
2. Obtaining Tax Clearance: Ensure all state tax obligations, including the annual franchise tax and any gross receipts fees, are paid with the Franchise Tax Board.
3. Filing a Certificate of Cancellation: File Form LLC-4/7, Certificate of Cancellation, with the California Secretary of State. This officially terminates the legal existence of the LLC.

Simply abandoning the LLC or failing to pay the annual franchise tax can lead to penalties and continued obligations. For detailed steps, see how to dissolve an LLC in California.
