California LLC Statement of Information: Step-by-Step Filing Guide (2026)

If you own an LLC in California, the Statement of Information is one of the easiest filings you will ever deal with. It takes about five minutes and costs $20. But if you forget it, the state will charge you $250 and could eventually suspend your business. That is a 1,150% markup for being late.

Here is everything you need to know about filing Form SI-550.

What Is the Statement of Information?

The Statement of Information (Form SI-550 for LLCs) is a filing with the California Secretary of State that confirms or updates basic information about your business:

• LLC name and entity number
• Principal office and mailing address
• Names and addresses of managers or members
• Registered agent for service of process

No financial information, no tax data, no revenue reporting. Just basic contact and management details.

When Is It Due?

Initial filing: Due within 90 days of your LLC's formation date. This is the one most new business owners miss.

Biennial filing: After that, you file every two years during your filing month (the month your LLC was formed). You have a six-month window starting from your filing month.

For example, if your LLC was formed in March 2024, your next filing is due anytime between March 1 and August 31, 2026.

Cost and Penalties

The filing fee is $20. If you file late, the penalty is $250. Continue to ignore it, and California can suspend or dissolve your LLC, meaning you lose the legal protections that come with your entity structure.

A suspended LLC cannot use California courts to enforce contracts, cannot defend lawsuits, and may lose the right to its business name. Reinstatement requires filing all overdue statements, paying all penalties, and filing a Certificate of Revivor.

How to File Online (Step-by-Step)

Online filing is the fastest method. Here is exactly how to do it:

Step 1: Go to bizfileOnline.sos.ca.gov

Navigate to the California Secretary of State's bizfile portal. You do not need an account to file, but having one makes tracking easier.

Step 2: Search for Your LLC

Look up your LLC by name or entity number. Your entity number is a 12-digit number on your Articles of Organization or any previous filing confirmation.

Step 3: Click "File a Statement of Information"

Select the option to file a Statement of Information from your LLC's record page.

Step 4: Verify or Update Member/Manager Information

Review the information currently on file. If anything has changed—new members, a manager who left, updated addresses—correct it now.

Step 5: Update Your Registered Agent If Needed

If you have changed registered agents, update it here. The agent must have a physical California street address (not a P.O. box).

Step 6: Pay the $20 Fee

Pay by credit card or bank transfer. Payment processes immediately.

Step 7: Download Your Confirmation

Save or print the confirmation for your business records.

Filing by Mail

Download Form SI-550 from the Secretary of State's website and mail it with a $20 check to:

Secretary of State, Business Programs Division, P.O. Box 944230, Sacramento, CA 94244-2300

Processing takes two to three weeks, compared to immediate processing online.

Common Mistakes to Avoid

Using the wrong entity number. Do not confuse your 12-digit entity number with your EIN or California tax ID. The wrong number can cause rejection.

Listing outdated manager or member information. If membership has changed since your last filing, update it. Filing with outdated details defeats the purpose.

Forgetting to update your registered agent. If your agent moved or you switched services, update this immediately. An unreachable registered agent means you will not receive legal notices.

Waiting until the last day of your filing window. You have six months, but if something goes wrong with your submission on the final day, you will not have time to fix it before penalties apply.

Confusing SI-550 with SI-100. Form SI-550 is for LLCs. Form SI-100 is for corporations. If you have both entity types, file the correct form for each.

Pro Tips

File early in your window. There is no benefit to waiting. File in month one of your six-month window and move on.

Set a reminder for 60 days before your filing month. That gives you time to gather any updated information.

Keep your registered agent current year-round. You can file an updated Statement of Information at any time if your agent changes mid-cycle (same $20 fee).

The Bottom Line

The California LLC Statement of Information is a $20 filing that takes five minutes. The penalty for forgetting is $250, and prolonged non-compliance can cost your LLC its good standing—or its existence. Mark your filing month, file early, and keep your records current.
