DIY vs. a Formation Service
Filing a California LLC yourself on the Secretary of State's bizfile Online portal costs $70 when you submit. That is only the first of several bills. A new California LLC also owes the $800 annual tax to the Franchise Tax Board in its first year and a $20 Statement of Information within 90 days. After that come recurring deadlines that carry penalties when they slip. The real comparison between filing yourself and using a formation service is not $70 versus a service fee. It is the full first-year and ongoing cost of each path, including the risk of mistakes and the hours it takes to get every step right.
This guide lays out those costs line by line for 2026, using figures published by the California Secretary of State, the Franchise Tax Board (FTB), the IRS, and FinCEN. Fees and rules change, so confirm each figure with the agency that sets it before you file.
The minimum first-year cost of a do-it-yourself California LLC is about $890. That total is made up of three charges:
That floor assumes you act as your own agent for service of process, get your EIN free from the IRS, and write your own operating agreement.
The $800 is the line most first-time owners leave out of their budget. California's temporary first-year exemption covered only LLCs with tax years beginning on or after January 1, 2021, and before January 1, 2024, so an LLC formed in 2026 owes the full amount in its first year. The tax is owed even if the LLC conducts no business, and it continues until the LLC is cancelled.
After year one, the recurring floor is $800 a year to the FTB plus $20 every two years to the Secretary of State. An LLC with more than $250,000 in income also owes a separate fee, which must be estimated and paid by the 15th day of the sixth month of the current tax year.
A DIY California LLC costs $70 to form and at least $800 per year to maintain, plus $20 every other year. That minimum does not include penalties, local licenses, or professional help. Here is how the costs break down by timing.
Forming an LLC on your own costs only the state fees. A formation service costs the same state fees plus its own fee, which ranges from $0 for a basic filing tier to a few hundred dollars a year for bundled compliance support, with agent service usually priced as a separate add-on. The state charges the same amounts no matter who submits the paperwork. The table below compares typical California costs for each path.
| Cost item | DIY on bizfile Online | Through a formation service | Who sets it |
|---|---|---|---|
| Articles of Organization (LLC-1) | $70 | $70 (passed through to the state) | Secretary of State |
| Initial Statement of Information (LLC-12) | $20, you file it | $20 state fee; filing may be included in a compliance plan | Secretary of State |
| Biennial Statement of Information | $20 every two years | $20 state fee; reminders or filing depend on the plan | Secretary of State |
| Annual franchise tax | $800 per year | $800 per year (never covered by a service) | Franchise Tax Board |
| Income-based LLC fee | $900 to $11,790 if income is $250,000 or more | Same | Franchise Tax Board |
| Agent for service of process | $0 if you serve yourself | Varies by provider; usually an annual add-on ($199 a year at ZenBusiness, or $99 for the first year when added at formation) | Service provider |
| EIN | $0 from the IRS | $0 or included in a paid tier | IRS |
| Service fee | $0 | $0 for basic tiers; paid tiers carry an annual fee | Service provider |
| Late Statement of Information penalty | $250 | $250 (less likely with tracked deadlines) | Secretary of State / FTB |
| Late franchise tax | Penalties plus interest; possible suspension | Same obligation; reminders reduce the risk | Franchise Tax Board |
| Name correction after approval | $30 (Certificate of Amendment or Correction) | $30 state fee; some plans include amendments | Secretary of State |
Using those figures, a realistic first-year comparison looks like this:
An LLC formation service typically starts at $0 plus state fees for the basic filing. Higher tiers cost more and add faster submission, an EIN, an operating agreement template, and ongoing compliance tracking, while registered agent service is usually a separate add-on. A service never replaces the state's fees; you still pay the $70, the $20, and the $800.
ZenBusiness is one example. It prepares and files formation documents, offers registered agent service, sends compliance and deadline alerts, can obtain an EIN, and provides operating agreement templates. Its California comparison page, updated in September 2026, listed these prices:
Starter also includes one optional free year of the company's compliance service, which then renews at $199 a year. Prices change, so confirm current terms on the provider's site.
The tradeoffs work in both directions. Filing yourself, you can submit Form LLC-1 the moment it is ready. ZenBusiness listed a 7 to 10 business day submission window for Starter and 1 business day for Pro and Premium, with rush submission available on Starter for an extra charge. The state's own review time applies no matter who submits. In exchange, the service reviews filings before submitting them and backs the work with an accuracy guarantee. ZenBusiness's own breakdown of doing it yourself versus a service walks through which steps each path puts on the owner.
A service does not take on the owner's legal obligations. It files on your behalf and helps you stay compliant. The LLC still owes the franchise tax, still needs a valid agent for service of process, and still answers for any missed filing.
Most DIY mistakes cost little to fix when caught early and a great deal when caught late. The expense usually comes less from the fix itself than from the time it takes to notice the problem and the penalties that build in the meantime.
If no one is available to accept legal papers at the address on file, a plaintiff can ask the court to allow service through the Secretary of State. The LLC may not learn about the lawsuit until it is too late to respond. California requires the agent to be a California resident with a physical street address in the state, or a registered corporate agent, and a PO box does not qualify. The state charges $50 for substituted service of process. The larger risk is a default judgment in a case you never saw.
Missing the Statement of Information leads to a $250 penalty, and continued failure can end in suspension. The Secretary of State gives a 60-day grace period from the date of notice. Owners who still have not filed after that pay a $250 penalty. The penalty rests on sections 17713.07(b) and 17713.09 of the Corporations Code and section 19141 of the Revenue and Taxation Code. Because the first filing is due within 90 days, it is the deadline new California owners miss most often.
Paying the annual tax late adds penalties and interest, and the FTB can suspend the LLC. California law authorizes the FTB to suspend an LLC's powers, rights, and privileges for unpaid fees or unfiled tax returns. A suspended LLC cannot legally do business in California. Reviving it means filing the overdue documents and paying what is owed.
The EIN is free directly from the IRS, and the common errors involve timing and details rather than cost:
No. Under FinCEN's current rules, a domestic LLC formed in California is not required to file a Beneficial Ownership Information report. The final rule took effect August 14, 2026, and adopted the narrowed reporting requirements from the March 2025 interim rule. FinCEN now states that U.S. companies are exempt from BOI reporting and that only certain foreign companies registered to do business in the U.S. must report.
The DIY mistake now runs the other way. Owners who assume they owe a BOI filing, or who pay a vendor to submit one, spend money on a report current guidance does not require. Check FinCEN's BOI page for the latest guidance before acting.
An operating agreement is not filed with the state, so many owners skip it. Going without one leaves disputes to California's default LLC rules and weakens the record that the business is separate from its owner. That separation matters even for a single-member LLC, because courts look at how the business was run when deciding whether to respect the liability shield. Drafting one costs nothing but time, and templates are widely available.
Fixing a California filing mistake usually costs $0 to $30 in state fees, plus the time to catch it:
The larger cost comes when a lapse in good standing blocks a certificate of status. Lenders, landlords, and some clients ask for one before they will sign.
Filing a California LLC yourself is the cheapest option in pure cash only if every deadline is met. For first-time owners, a formation service is often the better value. At a $0 basic tier, a service costs the same $890 in year one as filing yourself, so the only question is whether its paid features are worth their annual fee.
The math is straightforward:
None of these outcomes is common for owners who track every date. But first-time owners have the least experience tracking deadlines across California's two separate agencies.
DIY remains a sound choice for owners who:
For everyone else, a service such as ZenBusiness trades a known, modest fee for filing review, an accuracy guarantee, and deadline alerts across both agencies. The state fees stay the same. What changes is who carries the work of keeping up with them.
The state fees are the same whichever path you choose, so the decision comes down to how much of the filing and tracking you want to handle alone. If you would rather have the paperwork reviewed before it reaches the Secretary of State and get alerts before each deadline, start with the ZenBusiness California LLC formation service and keep your attention on building the business.
