What is a single-member LLC in California?
A single-member limited liability company (SMLLC or single-member LLC) is a limited liability company with only one member. “Member” is another name for an owner of an LLC.
Many California entrepreneurs decide it’s time to form an LLC because an LLC offers personal asset protection and a California sole proprietorship doesn’t. Sole proprietors don’t have to file any formation paperwork with the state, but if they’re sued or default on a business debt, their personal assets are at risk. In contrast, an SMLLC is a separate legal entity from its owner; the owner’s assets usually won’t be taken if there’s legal trouble.
How to Start a California SMLLC in 6 Steps
Starting a California LLC is a detailed process, but we’ve got a checklist to help guide your efforts. There are six essential steps to starting a California single-member LLC.
One quick note before we dive in: licensed professionals, such as doctors, dentists, and accountants, can’t form an LLC. California also doesn’t have a PLLC (see PLLC definition) option, either. If you’re in a licensed field, you’ll probably need to form a professional corporation instead.
Step 1: Pick a name for your single-member LLC in California
What will Californians call your single-member LLC? It’s time to find out. In the end, you want to create a business name you like that describes what you do. It should be memorable for your customers, too. But it’s also imperative that you comply with California naming laws. California law requires your LLC name to:
- Be “distinguishable” from other California business names. You can use our free California business name search tool to check that your name isn’t already claimed in California.
- Avoid misleading the public about your business purpose.
- Include a designator that shows you’re an LLC. California allows you to include the phrase “limited liability company” or the abbreviations “LLC.” or “L.L.C.” You can abbreviate “limited” with “Ltd.” and “Company” with “Co.” if you wish.
- Avoid the following restricted words: bank, trust, trustee, incorporated, inc., corporation, corp., insurer, insurance company.
Ideally, your name should also match an available domain name so customers can easily find you online.
Already picked a name but feeling time-crunched? You can reserve a California LLC name (the California filing fee is $10) to buy yourself an extra 60 days, and we can reserve your name for you. Our domain name service also starts out at just $25 a year.
Step 2: Get an agent for service of process in California
Every SMLLC is required to appoint an “agent for service of process in California,” sometimes called a registered agent. This agent accepts service of process and Secretary of State notices on your behalf. It’s a vital role for protecting your business.
According to California law, your service of process agent may be a natural resident of the state or a corporation that has applied to serve as an agent. These agents must provide their registered office address, and they have to be present and available at that address during all regular business hours.
We can provide you with a California agent for service of process with our registered agent service.
Step 3: File your California Articles of Organization
Once you’ve picked a business name and agent, you’re all set to file your formation documents, the Articles of Organization. California requires LLC formations to be filed online through bizfile Online. Please note that everything listed on this document is part of the public record, but once it’s complete, your SMLLC is officially formed.
What to Include in Your Articles of Organization
The state asks for a lot of important information on your Articles of Organization. You’ll list your business name, your mailing addresses, your agent’s information, and a few other basic details. California also asks who will manage the SMLLC (members or managers). The last section requires the signature of the organizer, the person submitting the Articles.
Not a fan of paperwork? Our zero-cost CA SMLLC formation service can take that stress off your plate.
Step 4: File the CA Statement of Information
Within 90 days of completing your Articles of Organization, you’ll need to submit a California Statement of Information. This report essentially updates the state about any information that might have changed in the initial start-up process, such as your address or other contact information.
There’s a $20 filing fee that accompanies this initial statement. In the future, the statement of information will also act as your biennial report (an ongoing compliance requirement that we can help with).
Step 5: Create a California SMLLC operating agreement
A California operating agreement is kind of like a charter or constitution for your SMLLC; it dictates exactly how your limited liability company will operate. (For more information, please see our operating agreement definition page.) Typically, the operating agreement explains the responsibilities of each member, how business profits will be distributed, how new members can be added, and more. California doesn’t require you to file your operating agreement; it’s an internal legal document.
Even though you aren’t a multi-member LLC, it’s a good idea to create an operating agreement. You never know how your business will grow in the future. Plus, having an operating agreement in place fortifies your personal liability protection because it’s another thing to demonstrate to the courts that you and your LLC are indeed separate legal entities (in case someone ever tries to challenge that in order to go after your personal assets).

Step 6: Get a single-member LLC EIN
An EIN, or employer identification number, acts like a Social Security number for a business. You can apply for one for free with the IRS (or we can tackle this task for you, if you prefer).
If you plan to have any employees or want to get a separate business bank account, you’ll need an EIN. Some single-member LLC owners can technically avoid this step, but many will find it helpful to have one.
California Single-Member LLC Taxes
For federal income tax purposes, an SMLLC is called a “disregarded entity.” In disregarded entities, the business qualifies for pass-through taxation. The LLC itself doesn’t file a tax return; the business owner reports their business income on their personal income tax return and pays taxes accordingly.
In many states, this process repeats on the state level; California works a little differently. You’ll still pay state income taxes on your personal tax return, but your LLC will also be subject to the California annual franchise tax. This tax has a minimum fee of $800 that applies to almost all business entities in the state. It’s one reason that California is a pretty costly state to run an SMLLC.
Note: business taxes are very complicated. Our guide to California small business taxes is a good starting point, and we highly recommend consulting with a tax attorney or CPA to get professional assistance.
Benefits of an SMLLC in California
Still wondering why you should form a California SMLLC? Here are some of the top benefits of starting a single-member LLC. For a broader look, see our guide to the benefits of a California LLC.
Flexibility and Easy Maintenance
An LLC takes some legwork to start, but it’s pretty easy to run compliantly: file your biennial report, maintain your agent, pay your taxes, and stay up-to-date on business licenses. Compared to other business entities like corporations, the LLC is super easy to run.
Business Autonomy
As the sole owner of your LLC, you get to call the shots. You won’t have to answer to shareholders, other members, or investors. Multi-member limited liability companies require more teamwork and compromise.
Personal Liability Protection
Since the SMLLC is a separate legal entity, you usually can’t lose your personal property (think your car, your home, or your personal savings) if the business gets into trouble. Operating as a sole proprietor wouldn’t give you that protection. California treats single-member and multi-member LLCs the same here; see how LLC protection in California works.
Taxation Options
Taxes in California aren’t cheap, but the luxury of an SMLLC is that you can choose how to be taxed. For both federal tax purposes and state ones, your default tax status is pass-through taxation. This lets you avoid the dreaded double taxation of a C corporation (the default form of corporation). That said, if you want to opt into corporate income taxes or elect S corporation status, you have that choice. Many LLCs opt to be taxed as S corporations (please see our What is an S Corp? page) in order to lower the amount of taxes they pay for Social Security and Medicare. Our guide to the California S corporation explains how that election works at the state level.
Extra Brand Legitimacy
Running your business as a sole proprietor is perfectly legal, but some customers feel more comfortable interacting with a registered business. The designator “LLC” can add a lot of weight to your name.
