California courts won't respect the corporate veil if you don't respect it yourself. Failure to maintain corporate formalities is one of the most common factors in "alter ego" cases where courts pierce the veil and hold shareholders personally liable.

Personal Liability
Court Scrutiny
Missing statements, incomplete minutes, or gaps in tax filings are red flags that can kill deals, reduce valuations by hundreds of thousands of dollars, or force unfavorable terms during fundraising or acquisition.
Valuation Impact
Failed Deals
Investor Concerns
A suspended corporation cannot legally conduct business in California, cannot sue to enforce contracts (though it can be sued), and may find contracts entered during suspension are voidable. Public record shows your "SUSPENDED" status to anyone who checks.
No Legal Standing
Public Record
Voidable Contracts
Corporations with clean records, current filings, and proper documentation command higher valuations, attract better investors, and maintain strong liability protection. The cost of compliance is a fraction of the cost of non-compliance.

⚠️ Three Critical Reasons Compliance Matters
1. Veil Protection: Courts examine whether you maintained formalities when deciding to pierce the corporate veil. No minutes for five years? You're providing evidence the corporation wasn't truly separate from you.
2. Due Diligence: Purchase prices reduced by hundreds of thousands because records are a mess. The cost of maintaining proper records is a fraction of scrambling to reconstruct them—or explaining why they don't exist.
3. Suspension: Anyone can check your status through the Secretary of State's online database. Operating with "SUSPENDED" next to your name destroys credibility with clients and partners.
California corporations must file SI-550 both initially (within 90 days of incorporation) and annually during a six-month filing period. This public filing contains names/addresses of CEO, Secretary, CFO, principal office address, and business type.
Initial Filing:
Within 90 days of incorporation
Annual Period:
Calendar month of incorporation + 5 preceding months
Fee:
$25 (verify current fee)
Filing Method:
Online via BizFile system (recommended)
Failure to file triggers multiple consequences: FTB penalty ($250), potential SOS suspension/forfeiture, and cannot revive FTB suspension until all SI filings are current. The requirements stack—you can't just pay taxes and ignore SI filing.

SOS Suspension
Public Record
Corporations with equity securities registered under Exchange Act § 12 or required to file under § 15(d) have additional disclosure obligations. Must file separate "Corporate Disclosure Statement" with enhanced director, executive compensation, and governance information.

⚠️ Filing Period Confusion
Your filing period is NOT just the month you incorporated. It's that calendar month PLUS the five preceding months. If you incorporated in March, you can file anytime from October through March. File early in the window to avoid complications.
💡 Pro Tip: Don't Wait for Notices
While the Secretary of State typically sends notices, don't rely on receiving them. Set your own calendar reminders when you incorporate. Missing the 90-day initial deadline or annual period starts the penalty clock immediately.
Every corporation must hold annual shareholder meetings for director election. Can satisfy through unanimous written consent instead of formal meetings. Cannot simply skip without documentation—this is a classic veil-piercing factor.
Requirement:
Annual election of directors
Alternative:
Unanimous written consent
Risk if Skipped:
Veil-piercing evidence, DD red flags
Board can act through meetings or unanimous written consent. Minimum annually: approve financials, ratify officer compensation, approve equity grants, review major contracts, confirm compliance. Written consents must be actually signed and maintained.
Annual Minimum
Must Sign Consents
Document All
Must keep "adequate and correct books and records" and minutes of all proceedings. This isn't a suggestion—it's a statutory mandate. Courts examining veil-piercing routinely cite inadequate recordkeeping as evidence corporation wasn't truly separate.
Required Records:
Minutes, accounting books, shareholder records
Must Include:
Who, what, when, why of major decisions
Organization:
Must be accessible and current
Board must send annual financial report (balance sheet, income statement, cash flows) within 120 days of fiscal year end. EXCEPTION: Corporations with <100 shareholders can waive in bylaws. Most startups/closely held corps waive this requirement.
Deadline:
120 days after fiscal year end
Waiver Option:
< 100 shareholders can waive in bylaws
Content:
Financials + accountant report or officer cert
⚠️ What Constitutes "Adequate" Minutes
Minutes should document who was present, what was decided, when it occurred, and why (for non-routine actions). Not elaborate transcripts, but clear professional records that could withstand scrutiny from judges, investors, or buyers. Don't be so sparse they're meaningless or so detailed they document every internal debate.

💡 Shareholder Inspection Rights (Corp Code §§ 1600-1601)
Shareholders can inspect and copy shareholder lists, bylaws, minutes, accounting books, and board proceedings for proper purposes. If you deny a justified request, shareholders can seek court enforcement and recover attorney's fees. You can't deny inspection because records don't exist—that's an admission of non-compliance.

⚠️ S Corporation Reasonable Compensation (IRS Requirement)
The Issue: S corp shareholder-employees must receive reasonable compensation as wages (subject to employment taxes). Distributions are not subject to employment taxes, creating incentive to minimize wages and maximize distributions.
The Risk: IRS will reclassify distributions as wages, assess employment taxes retroactively, plus penalties and interest. The corporation faces penalties for failure to withhold and pay employment taxes when due.
What's Reasonable: Approximate what you'd pay an arm's-length third party for the same role. Consider training, experience, duties, time devoted, comparable businesses, documented agreements. CEO working full-time should be paid accordingly.
Annual Compliance: Board should formally approve officer compensation in minutes/consent each year, referencing reasonableness factors. Document basis for compensation level. Actually pay salary through regular payroll with proper withholdings.
Additional Trap: >2% shareholders: health insurance premiums paid by corp must be included in W-2 wages (not subject to employment taxes, but subject to income tax).
💡 Revival Cost Example
Corporation suspended for 3 years owing $800 annually. Revival requires: $2,400 base tax + failure to file penalties (% of tax) + failure to pay penalties (% of tax) + daily compounding interest. Total can easily reach $5,000-$10,000 or more. Prevention through timely filing is far cheaper than revival.

Frequently Asked Questions
What happens if I miss the Statement of Information deadline by just a few days?
▼
Even a brief delay can trigger consequences. The FTB can assess the $250 penalty under Revenue and Taxation Code Section 19141 for failure to file on time. While the Secretary of State may not immediately suspend your corporation for a minor delay, the filing isn't considered timely and penalty exposure exists. More importantly, if you're habitually late, it signals to potential investors or buyers that your corporate governance is lax. File during your six-month filing period—there's no reason to wait until the last day when you have months to complete it.
Do single-shareholder corporations really need to hold annual meetings and keep minutes?
▼
Yes, even if you're the sole shareholder and director, corporate formalities still matter. The law doesn't exempt single-shareholder corporations from governance requirements. Courts evaluating whether to pierce the corporate veil look at whether formalities were observed regardless of shareholder count. The practical reality is that single-owner corporations can satisfy these requirements through written consents rather than formal meetings, which is much simpler. Prepare an annual written consent as the sole shareholder electing yourself as director, and a board consent approving key actions for the year. It takes minimal time but provides critical documentation that the corporation was properly maintained as a separate entity.
Can I backdate board minutes or shareholder consents if I realize I forgot to do them?
▼
No. Backdating corporate documents is not only ineffective, it's potentially fraudulent. If you discover you failed to hold required meetings or prepare consents, the proper approach is to document the situation accurately going forward. You can prepare ratification resolutions where the board or shareholders acknowledge that certain actions were taken in the past and now ratify and approve those actions as of the current date. This creates a contemporaneous record without falsifying dates. If you're facing due diligence and discover gaps in your corporate records, address them transparently with buyers or investors rather than trying to manufacture false documentation. Sophisticated parties will often discover backdating through metadata in electronic documents or inconsistencies in the records, which destroys credibility and can kill transactions.
How do I determine what's "reasonable compensation" for myself as an S corporation shareholder-employee?
▼
Start by researching what comparable positions earn in your industry and geographic area. Look at salary data for executives with similar responsibilities, experience levels, and company sizes. Websites like Glassdoor, Salary.com, or Bureau of Labor Statistics data can provide benchmarks. Consider the amount of time you're dedicating to the business—if you're working full-time, your salary should reflect that. A reasonable approach is to ask yourself what you would need to pay an arm's-length third party to perform your role. Document your analysis in your board minutes when approving compensation. If your corporation is profitable and you're taking distributions, make sure the salary is substantial enough that it doesn't appear you're trying to avoid employment taxes. Working with a CPA who has experience with S corporation compensation issues can help you strike the right balance between tax efficiency and defensibility.
If my corporation gets suspended by the FTB, can I just dissolve it and start a new one?
▼
This is a common but problematic idea. First, you can't properly dissolve a suspended corporation until you bring it back into good standing by satisfying all outstanding obligations. The Secretary of State won't accept a certificate of dissolution from a suspended entity. Second, if you form a new corporation to continue the same business while abandoning a suspended corporation with unsatisfied obligations, you risk successor liability claims and potential veil-piercing arguments that the new entity is merely a continuation of the old one designed to evade liabilities. Third, forming a new entity doesn't eliminate your personal obligations to deal with the suspended corporation's tax debts—the FTB can pursue collection against responsible officers and shareholders in some circumstances. The proper approach is to revive the suspended corporation by filing past-due returns, paying outstanding taxes and penalties, and then either maintaining it in good standing or formally dissolving it after satisfying all obligations.
What's the difference between the Statement of Information and the annual report to shareholders?
▼
These are completely different requirements that serve different purposes. The Statement of Information (SI-550) is filed with the Secretary of State under Corporations Code Section 1502 and is a public regulatory filing containing basic information about your corporation's officers and business address. Everyone can access this information through the Secretary of State's business search. The annual report to shareholders under Corporations Code Section 1501 is an internal corporate governance obligation requiring the board to send financial statements to shareholders. This is not a public filing—it's sent directly to shareholders and is not filed with any government agency. Many corporations with fewer than 100 shareholders waive the Section 1501 annual report requirement in their bylaws, but the Statement of Information must always be filed regardless of shareholder count. Both are separate from your FTB tax return filing obligations.
As a California corporation, do I need to do anything at the county level for business licenses?
▼
Corporate formation and annual maintenance at the state level—through the Secretary of State and Franchise Tax Board—is distinct from local business licensing. Most California cities and counties require businesses operating within their jurisdiction to obtain local business licenses or permits. These are separate from your corporate status and are typically based on where you physically operate your business. Requirements vary significantly by locality—some cities charge flat annual fees, others charge based on gross receipts or number of employees. Contact your city or county business licensing office to determine what's required for your specific situation. Additionally, depending on your business type, you may need specialized permits or licenses (health permits for restaurants, professional licenses for certain services, sales permits if you sell goods, etc.). This article focuses on corporate-level compliance, but local business licenses are a separate layer of compliance you shouldn't overlook.
How long should I retain corporate records and tax returns?
▼
For tax purposes, the general rule is to retain corporate tax returns and supporting documentation for at least four years from the later of the due date or the date you filed the return. California's statute of limitations for tax assessments is generally four years, though it extends to eight years if you substantially understate income. The IRS has a three-year statute for most assessments and six years for substantial omissions. However, from a corporate governance and veil protection standpoint, I recommend retaining core corporate documents indefinitely—articles of incorporation, bylaws, minutes of major decisions, stock issuance records, and material contracts should be permanent records. These documents establish the corporation's history and may be needed decades later if ownership is questioned or historical corporate actions become relevant in litigation. For routine annual minutes and consents, many corporations maintain them indefinitely simply because the storage burden is minimal and there's no compelling reason to destroy corporate governance records.
I'm a foreign corporation qualified to do business in California—do all these requirements apply?
▼
Yes, with some modifications. Foreign corporations (meaning corporations incorporated in another state but qualified to do business in California) must file annual Statements of Information using Form SI-550 (or the foreign corporation equivalent) and must file California tax returns (Form 100 or 100S) if they have sufficient California nexus. The $800 minimum franchise tax applies to qualified foreign corporations. Your corporate governance obligations—board meetings, shareholder meetings, minutes—are primarily governed by your state of incorporation, but California will still examine whether you observed corporate formalities if veil-piercing issues arise in California litigation. If you're a foreign corporation, make sure you're tracking compliance requirements in both your state of incorporation and in California. The Statement of Information filing period for foreign corporations is based on the date you qualified to do business in California, not your original incorporation date in your home state.
Can I use electronic signatures for board consents and other corporate documents?
▼
Yes. California law recognizes electronic signatures under the Uniform Electronic Transactions Act (California Civil Code Section 1633.1 et seq.). Electronic signatures have the same legal effect as handwritten signatures for most corporate documents, including board consents, shareholder consents, and corporate resolutions. However, there are some practical considerations. First, make sure your electronic signature process creates a reliable record that can be authenticated later—major e-signature platforms like DocuSign, Adobe Sign, or HelloSign provide audit trails and verification features that help establish authenticity. Second, ensure that your bylaws don't prohibit electronic signatures (most modern bylaws either explicitly permit them or are silent, which allows them under California's default rules). Third, keep in mind that some third parties may request original wet-signature documents for major transactions even though electronic signatures are legally valid. For routine corporate governance, electronic signatures are efficient and perfectly acceptable.
