DIY vs. a Filing Service for a California LLC: The Real Cost in 2026

What does filing a California LLC yourself really cost, up front and ongoing?

Filing a California LLC on your own is not expensive at the moment of formation, and it is worth saying so plainly. The up-front cash is the $70 Secretary of State filing fee for the Articles of Organization, plus the $20 fee for the initial Statement of Information (Form LLC-12), which is due within 90 days of formation. If you complete both yourself, your first out-of-pocket total to the state is about $90.

The number that changes the picture is the annual tax. California charges every LLC that is organized in or doing business in the state an $800 minimum annual franchise tax, collected by the Franchise Tax Board under Revenue and Taxation Code section 17941, and it applies regardless of profit or loss. The first-year waiver that some older guides still describe (created by Assembly Bill 85) applied only to LLCs formed between January 1, 2021 and December 31, 2023, and it has expired. Any LLC formed on or after January 1, 2024 owes the full $800 in its first year, due by the 15th day of the fourth month after formation, and then by April 15 each year for a calendar-year LLC. So the direct answer to "how much does it really cost to start a California LLC on my own, including the franchise tax" is roughly $90 to the Secretary of State in the first few months, plus $800 to the Franchise Tax Board in year one, which puts a realistic first-year figure near $890 before you add a registered agent or anything else. There is also a separate income-based LLC fee that starts at $900 and applies only once California-source income reaches $250,000 in a year, so most new, small LLCs will not trigger it, but it is worth knowing it exists.

The ongoing costs are where DIY quietly gets more expensive, mostly because nothing is tracking them for you. The items below are the ones first-time owners most often miss:

• The $800 franchise tax, every year. It recurs annually for the life of the LLC. Missing or paying it late brings penalties, interest, and eventually suspension of the LLC's rights by the Franchise Tax Board.
• The biennial Statement of Information. After the initial filing, California LLCs must file Form LLC-12 every two years for a $20 fee. The first one, due within 90 days of formation, is the filing people miss most, because it lands early and then the two-year cycle is easy to lose track of.
• A registered agent, called an agent for service of process in California. State law requires one with a physical California street address available during business hours. Acting as your own agent costs nothing in cash but puts your address on the public record and ties the LLC's legal notices to your personal availability.
• Business licenses and local renewals. Many California cities and counties require a business license or tax registration that renews on its own schedule, separate from anything the state tracks.
• Your time. The research, the form, the tax voucher, the report, and the calendar entries are all yours to manage. That time has value, and it is a real part of the DIY cost even though no invoice ever shows it.

What does it cost when a California LLC filing goes wrong?

The strongest argument against the "$70 and done" view is not the fees you can see. It is the cost of the mistakes that are easy to make when no one is checking the work. These are the failure points that show up most often, and what each one actually costs.

Registered agent errors. Every state, California included, requires a registered agent (agent for service of process) with a real in-state street address available during business hours. Listing your home address makes it public and permanent until you file to change it, and if you are unreachable when a lawsuit is served, you can lose by default without ever knowing you were sued. This is one of the clearest reasons to weigh the risks of filing yourself against handing the role to a service with a staffed address.

Missed ongoing deadlines. The Statement of Information and the franchise tax are the two most commonly missed obligations, and both carry teeth. California assesses a $250 penalty for a delinquent Statement of Information, and continued failure can lead to suspension of the LLC by the Secretary of State. A late or unpaid franchise tax brings its own penalties and interest from the Franchise Tax Board, plus suspension. The initial Statement of Information, due about three months after formation, is the single most missed filing, precisely because it comes due before most owners have settled into any routine.

The EIN step. An Employer Identification Number is free directly from the IRS, and you should get it there rather than paying a third-party "EIN filing" site for something the IRS gives away. The common self-filing errors are applying before the state has actually approved the LLC, naming the wrong responsible party, and choosing a tax classification without realizing that changing it later means additional IRS paperwork. None of these is catastrophic, but each is a time sink to unwind.

The beneficial ownership (BOI) misconception. This one has flipped, and old advice is now wrong. Under a FinCEN final rule effective August 14, 2026, entities created in the United States, including the typical domestic LLC, are exempt from filing a Beneficial Ownership Information report. The reporting requirement now applies only to certain foreign-formed entities that register to do business in the US. The DIY mistake in 2026 is assuming your domestic California LLC owes a BOI filing, or paying a site to file one for you, when current FinCEN guidance does not require it for a domestic LLC. Check FinCEN's current guidance before acting, and do not pay for a filing you likely do not owe.

No operating agreement. California is one of the few states that technically requires an LLC to have an operating agreement under Corporations Code section 17701.10, though the agreement can be oral, written, or implied, and it is never filed with the Secretary of State. Because there is no filing and no direct penalty for skipping a written one, many owners skip it. The cost shows up later: without a written agreement, the default rules of California's Revised Uniform Limited Liability Company Act govern your profit splits, voting, and dissolution, and those defaults rarely match what the members would have chosen. It matters even for a single-member LLC, because a signed agreement helps establish the separation between owner and business that courts look for when deciding whether your liability shield holds, and banks often ask for it to open a business account.

Fixing mistakes after the fact. A rejected filing has to be corrected and resubmitted, and the state filing fee is often nonrefundable, so an error can mean paying twice. A mistake caught after approval (a misspelled name, a wrong address) is fixed with an Amendment to Articles of Organization (Form LLC-2), a separate filing with its own fee (California charges $30 for that amendment). And if a lapse pushes the LLC out of good standing, you can be blocked from getting a certificate of good standing that a lender, landlord, or client may require before they will do business with you. Each of these is cheap to prevent and mostly expensive in the time it takes to notice and unwind.

The bottom line for a first-time California LLC owner

If you are confident you will track the $800 franchise tax every April, file the Statement of Information on its 90-day and biennial schedule, keep a real registered agent address staffed during business hours, and skip paying anyone for an EIN or a BOI report you do not owe, filing yourself on bizfile Online is a legitimate way to save the service fee. If any of that sounds like something you would rather not be responsible for, a service earns its price by turning a scattered checklist into one guided process with deadline alerts behind it. For most first-time owners weighing convenience and compliance against a modest recurring cost, using a California LLC formation service is the lower-risk path, and it leaves you free to spend your time on the business instead of on the paperwork. Whichever path you choose, remember that a service files on your behalf and helps you stay compliant; it does not remove your legal obligation to pay the tax and file the reports.
