Should My Business Be an LLC? A Newport Beach CPA/CFP's Honest Guide
If a business involves contracts, clients, employees, or any realistic chance of a liability claim, forming an LLC is usually worth the cost. For a business already netting six or seven figures, pairing that LLC with an S corp tax election typically matters more to the bottom line than the entity decision alone.
Business owners in coastal Orange County ask this question constantly, whether running a consulting practice out of a home office in Corona del Mar, operating a boutique agency near Fashion Island, or managing a professional practice with a handful of employees. Katherine Leonard, CPA, CFP®, founder of KCL Wealth Management in Corona del Mar, breaks it down the way she breaks it down for her own clients: with a CPA's grasp of the tax return and a CFP®'s view of what actually happens to a family's wealth when the structure is wrong.
What an LLC actually is, in plain English
An LLC is a legal entity formed with the state of California that exists separately from its owner. Done correctly, it draws a line between the business and personal life: the owner's home, brokerage account, kids' 529 plans, the paddleboard sitting in the garage. If the business gets sued or racks up debt it can't pay, the claimant can generally only reach what's inside the LLC, not personal assets. That protection only works if the LLC is set up and maintained correctly, which is where Katherine sees most business owners in Newport Beach get tripped up.
Do I need an LLC for my business in California?
It depends on what the business actually does, not how much money it makes. Ask: Does the work involve advice, a service, or public interaction that could result in a harm claim? Are contracts, leases, or vendor agreements signed in the business's name? Are there employees or contractors? Could a dissatisfied client realistically sue? A yes to any of these makes an LLC foundational, not optional.
A worked example: what actually happens without one
Consider a Corona del Mar marketing consultant operating as a sole proprietor, no LLC, billing $400,000 a year. A former client claims the consultant's campaign caused a financial loss and sues for $250,000. Because there's no entity separating business from personal assets, the consultant's home equity, brokerage account, and savings are all fair game if the claim succeeds, not just the business's bank account. Had the same consultant operated through a properly maintained LLC, the claim would generally have been limited to what the LLC itself held. The legal exposure didn't change with revenue size, only the size of what was actually at risk.
LLC versus sole proprietorship: what's actually different
A sole proprietorship is the default, with zero legal separation between owner and business. Every dollar of liability the business creates is personal liability. An LLC changes that, changes how the business can be taxed, and adds legitimacy when negotiating contracts or credit. For owners in the $2M to $5M net worth range, Katherine considers that liability separation one of the most cost effective pieces of protection available.
What does forming and maintaining an LLC actually cost?
Expect a state filing fee around $70, an annual $800 minimum franchise tax regardless of income, and, once California-source gross receipts cross $250,000, an additional tiered fee ranging from $900 to $11,790 depending on revenue. Add modest costs for an operating agreement and annual bookkeeping separation. For a business netting well into six figures, this typically runs a few thousand dollars a year, a small fraction of what a single uninsured, unprotected lawsuit could cost.
What about the LLC plus S corp combination?
An LLC is a legal structure. S corp is a tax election made on top of it. Once a business is consistently profitable, generally once net income clears around $80,000 to $100,000 a year, the S corp election can meaningfully reduce self employment tax by splitting income between a reasonable salary and distributions. As both a CPA and CFP®, Katherine walks clients through this analysis regularly, since the IRS scrutinizes "reasonable compensation" closely. The LLC provides the legal shield, the S corp election provides the tax efficiency, and most established Orange County business owners benefit from having both working together.
When might an LLC not be the right first move?
For a business still being tested, with minimal contracts, strong personal umbrella insurance, and little revenue yet, waiting until there's real traction before adding the cost and administrative layer can be the smarter sequencing. This is a case-by-case call, not a blanket rule.
What an LLC won't protect against
An LLC does not protect against a business owner's own negligence or malpractice. A professional who personally causes harm generally isn't shielded from that specific claim by the LLC alone, which is what professional liability insurance is for. It also won't help against a personally guaranteed loan, commingled funds, or fraud.
When does this decision typically need revisiting?
Common triggers: revenue crossing roughly $250,000 (the point where the tiered LLC fee begins), taking on the first employee, signing a commercial lease, or adding a second line of business. Any of these meaningfully increases exposure and is worth a structure review, not just a tax season afterthought.
Frequently asked questions
Do I need an LLC if I'm a sole proprietor in California? Not legally, but if the work carries any liability risk, operating without one leaves personal assets exposed to claims against the business.
How much does forming an LLC in California cost? A state filing fee, an $800 annual minimum franchise tax, and potentially $900 to $11,790 more depending on income once revenue crosses $250,000.
Is an LLC or S corp better for a small business? They aren't competing options. The LLC is the legal entity; S corp is a tax election layered on top once the business is profitable enough to benefit.
Can I be personally sued even if my business is an LLC? Yes, if the harm was personally caused (such as malpractice), a debt was personally guaranteed, or personal and business funds were commingled.
Do I need a lawyer to form an LLC in California? Not legally required, but for a business with real revenue and assets at stake, having an attorney draft the operating agreement is worth the cost.
Where this fits into the bigger financial picture
Business entity structure isn't purely a legal question, it's a wealth management question, affecting the tax bill every year and how exposed a family's net worth is to a single bad year in the business. Established business owners in Newport Beach, Corona del Mar, and the surrounding coastal communities who aren't sure whether their current structure is doing its job are welcome to begin the conversation with Katherine Leonard.
