‹ California Filing Guide · All Penalties
Operating in California without a certificate of authority can trigger a civil penalty under state statute and bar your LLC from California courts. Here's the full cost.
California's LLC act doesn't charge a flat civil penalty for operating without registration, but the Franchise Tax Board does. If you're 'doing business' in California without a certificate of registration, you owe the $800 annual franchise tax for every year you operated, plus a $2,000 per-year FTB penalty if you fail to file the required return within 60 days of an FTB demand notice. You also can't sue anyone in California courts until you register, and you'll owe a $250 penalty for each missed Statement of Information.
| What's at stake | If you don't register | Severity |
|---|---|---|
| Civil penalty | $2,000 per taxable year, assessed by the Franchise Tax Board. The FTB assesses it only after you fail to file a demanded return within 60 days of the demand notice, and it repeats for each taxable year you stay unregistered. The $800 minimum franchise tax is separate: it is the tax you would have owed anyway, charged as a back fee rather than as a penalty. | High |
| Back fees on cure | You owe every fee and tax that would have been due if you had registered on time. That includes registration fees, biennial report fees, and franchise tax for each year unregistered. Interest accrues on unpaid amounts. | High |
| Right to sue in state court | Closed. You cannot bring or maintain any lawsuit in state court until you register. If you need to sue a customer, a partner, or a vendor, you have to register first. You can still defend yourself if someone sues you. | High |
| Contract validity | Your contracts stay enforceable. Failing to register does not void any deal you signed, and the other party still owes you what they agreed to. | Low |
| Personal liability | Your personal assets are still protected by the LLC. Failing to register does not by itself pierce the corporate veil. Other liability theories like veil-piercing, personal guarantees, and fraud are unaffected. | Low |
| State tax exposure | High. The Franchise Tax Board enforces a separate 'doing business' standard under R&TC section 23101 that catches LLCs the Secretary of State doesn't. If FTB determines you owe the $800 annual franchise tax, that obligation runs from the year you started doing business in California, regardless of whether you registered. | Medium |
| How it gets enforced | Collected by the Secretary of State at registration, or by enforcement action if you do not voluntarily register. | N/A |
California charges two different penalties that get confused with each other, and they come from two different agencies.
The penalty on this page is the Secretary of State consequence for doing business in California without a certificate of authority. It is triggered by operating unregistered, and it is cured by registering.
Separately, the Franchise Tax Board charges the $800 annual franchise tax and a late-filing penalty when the return or the tax is late. That one applies whether or not your registration is in order, and registering does not clear it. Our California franchise tax guide covers the amounts and due dates.
If you registered late, expect both: the registration consequence from the Secretary of State, and franchise tax owed for each year the LLC was doing business in California, including the years before you registered.
Here's how to fix it before any of this catches up to you.
You can file the foreign qualification yourself directly with the California Secretary of State for the standard filing fee. The application looks straightforward, but rejections are common. A wrong form version, a missing certificate of good standing from your home state, or a name conflict with an existing entity will bounce the filing and reset the clock by two to three weeks. Every week you stay unregistered is another week of penalty accrual.
Northwest reviews your application before it goes in, catches the rejection-causing mistakes (form version, name conflict, missing certificate of good standing), and submits same-day in most states. They'll also serve as your registered agent so the filing meets the statutory requirement on day one. If something is wrong, they fix it before the Secretary of State sees it, not after a rejection notice arrives three weeks later.
