The Hidden Liability and Tax Traps for San Diego Startups

The Law Office of David J. Hollander Nov. 13, 2026

Forming a company can feel like crossing a finish line, especially after months of building a product and finding your first customers. Many founders assume the filing itself protects everything they own.  

In reality, a new LLC or corporation does not automatically shield you from personal liability or tax surprises. Those gaps often surface only after a dispute, a notice from the state, or a lawsuit, and founders who are stretching limited time and cash may not have room to catch them early. 

The short answer is that a business entity can limit your personal exposure, but only when it is formed, funded, and operated correctly. Attorney David J. Hollander helps founders throughout San Diego County, California, set up and run their companies with these risks in mind. Contact his office to learn where your startup stands. 

Does Forming an LLC or Corporation Protect Your Personal Assets?

Usually it does, but the protection has limits. Under California Corporations Code section 17703.04, LLC members are generally not personally liable for the company's debts solely because they are members. Courts may look past that protection, however, when owners treat the company as an extension of themselves. 

Founders who personally guarantee a lease or loan also remain responsible for that debt, whatever entity they formed. Habits that can weaken the protection include: 

  • Paying personal expenses from the business account. 

  • Operating without a written operating agreement or bylaws. 

  • Signing contracts in your own name instead of the company's. 

  • Starting the business with too little capital to cover foreseeable obligations. 

Most of these problems are easy to prevent if you address them at the start. They can be hard to repair after a creditor or former partner raises them. 

California Taxes and Fees Founders Often Overlook

California LLCs generally owe a minimum annual franchise tax of $800, even if the company earns nothing. A bill for a company that hasn't yet generated revenue may strain a tight startup budget. LLCs with higher gross receipts may owe an additional annual fee, and first-year rules have changed over time, so confirm current requirements. 

Corporations face their own minimum franchise tax, and companies with employees must pay payroll taxes. Local business tax certificates may also apply depending on the city where you operate. Each is a small obligation on its own, but missed filings can add penalties and interest that a young company rarely planned for. 

Worker Classification Mistakes That Create Liability

California presumes a worker is an employee unless the business proves all three parts of the ABC test found in Labor Code section 2775. Early teams often rely on flexible help while cash is tight, so misclassification can happen without any intent to cut corners. The consequences may include back wages, unpaid payroll taxes, and penalties. 

In plain English, the test asks whether the worker: 

  • Is free from your control and direction in performing the work. 

  • Performs work outside the usual course of your business. 

  • Is customarily engaged in an independently established trade or business. 

Certain exceptions exist, and they vary by occupation and circumstance. A California business law attorney can review each role on your team and help you decide whether a contractor arrangement is likely to hold up. 

Equity and Founder Agreements That Cause Disputes Later

Handshake equity splits often cause founder conflict. Without a written agreement covering ownership percentages, vesting, and what happens when someone leaves, even friendly co-founders may find a disagreement costly to resolve. Putting those terms in writing early often protects the relationship as much as it protects the company. 

Issuing stock or membership interests can also trigger securities rules, which depend on how and to whom the interests are offered. Founders who receive stock subject to vesting may need to consider a federal Section 83(b) election, which generally must be made within 30 days of the transfer. Missing that deadline can lead to unexpected tax consequences, and it generally cannot be fixed afterward. 

Build Your California Startup With a Business Law Attorney

Forming an entity helps only when it is paired with careful record-keeping, accurate tax compliance, and clear worker and equity agreements. Each of these areas can quietly shift risk from the company back onto you.
