How to Close a Business in California: A Legal Guide to Dissolving Your LLC or Corporation

Business FormationJune 10, 2026

Closing a business is more involved than simply stopping operations. In California, failing to formally dissolve your LLC or corporation exposes you to continuing tax liability, personal liability claims, and Franchise Tax Board enforcement, even after your doors close. Here is what San Diego owners need to know about winding down correctly.

Why Proper Dissolution Matters

The most common mistake is assuming inactivity equals dissolution. It does not. Until you formally dissolve the entity and file your final return with the Franchise Tax Board (FTB), the entity remains legally alive, and the state keeps billing the $800 minimum franchise tax plus penalties and interest. LLCs with revenue over $250,000 also carry the gross receipts fee. These obligations accrue whether or not you operate.

Acting promptly has a concrete payoff. If you file a final return marked “final,” stop doing business in California, and complete the dissolution within 12 months of that filing, the FTB does not assess the minimum tax for that final year. Drag the process out past 12 months and you owe another $800.

Dissolving an LLC

A California LLC dissolution runs on two tracks: a legal dissolution with the Secretary of State and tax clearance with the FTB. The steps, in order, are to review the operating agreement for dissolution and voting procedures, obtain and document member approval, file Form LLC-3 (Certificate of Dissolution) if required, file Form LLC-4/7 (Certificate of Cancellation) or the short-form LLC-4/8 for eligible inactive LLCs under 12 months old, notify creditors and settle liabilities and distribute remaining assets, file a final Form 568 and pay all balances, file final federal returns marked final, close the EIN with the IRS in writing, and cancel local licenses, permits, and registrations.

Dissolving a Corporation

Dissolving a corporation requires shareholder action, and the threshold matters. If all outstanding shares vote to dissolve, no separate Certificate of Election to Wind Up and Dissolve is required, and that election can be stated in the Certificate of Dissolution. If at least 50% but less than 100% approve, a Certificate of Election to Wind Up and Dissolve must be filed before or with the Certificate of Dissolution. Corporations must also file IRS Form 966 within 30 days of adopting the plan, mail notice to creditors and non-consenting shareholders, file a final California return marked “final,” and settle all employment, sales, and city taxes. Note that California no longer requires a pre-dissolution tax clearance certificate from the FTB; the Secretary of State notifies the FTB of the dissolution directly.

Debts and Personal Liability

The wind-down includes a formal duty to notify creditors and provide for known liabilities before distributing assets. Skipping it can expose directors or members to personal liability for claims that surface later. The Certificate of Dissolution must affirmatively state that known debts have been paid, assumed, or adequately provided for.

When to Call Counsel

DIY dissolution often creates expensive problems. Get counsel involved where there is pending litigation or threatened claims, member or shareholder disputes over distributions, employee wage claims, leases with personal guarantees, or multi-state operations.
