The Wrong Entity Costs a San Diego Contractor About $6,000 a Year

Most contractors pick a business entity once, at the kitchen table, the week they get licensed. In California that choice has an annual price tag, and the CSLB makes changing your mind messier than it should be. Here is the actual math.

What staying a sole prop really costs

Take an Escondido electrical contractor who nets $160,000 after materials, crew, and overhead. As a sole proprietor, every dollar of that profit is hit with self employment tax: 15.3 percent on 92.35 percent of net earnings. That is about $22,607 before a dime of regular income tax gets calculated.

The part that stings is that self employment tax does not care whether you left the money in the business. Bought a van, stocked up on wire, let cash sit for winter, it all gets taxed the same. And as a sole prop, your house and personal savings sit behind every job you contract. Your $25,000 contractor bond protects the public, not you.

What an S corp actually changes

Run the same shop through an S corporation and the profit splits into two buckets. You pay yourself a reasonable W-2 salary, say $90,000 for an owner running crews in San Diego County, and payroll taxes apply only to that: about $13,770 counting both halves. The remaining profit comes out as a distribution with no self employment tax on it.

That is a swing of about $8,837. Now subtract the real costs of the structure: California charges S corps 1.5 percent of net income, about $950 here with an $800 minimum, plus roughly $700 a year for a payroll service and another $900 or so for the separate corporate return. You still come out around $6,300 ahead. Every year. That is a decent used compressor, annually, for filing different paperwork.

The catch is the word reasonable. Pay yourself $25,000 and take $135,000 in distributions and you have built the classic IRS audit flag. The salary needs to look like what you would pay someone else to do your job. The split also changes your 20 percent qualified business income deduction, so this is math worth doing precisely, not guessing.

Why California makes LLCs expensive for contractors

Plenty of contractors hear liability protection and reach for an LLC. In most states, fine. California charges contractors three separate premiums for that wrapper.

First, the FTB gross receipts fee. It is based on revenue, not profit, which is the worst possible design for a high revenue, thin margin business like construction:

A general contractor running $3M in revenue owes $6,000 plus the $800 minimum even in a break even year, because the fee never looks at profit.

Second, the CSLB requires LLC licensees to post a $100,000 employee and worker bond on top of the standard $25,000 contractor bond. Third, LLC licensees must carry at least $1M in general liability insurance, scaling up to $5M as the company grows. Corporations carry neither of those extra requirements.

Here is the same shop in both wrappers:

An LLC can elect S corp taxation, which kills the gross receipts fee. But the CSLB bond and insurance mandates follow the entity type, not the tax election, so an LLC taxed as an S corp still posts the $100,000 bond and carries the $1M policy.

The license number problem nobody mentions

Your CSLB license number carries your history: years in business, bid record, the track record a school district or GC checks during prequalification. Business and Professions Code section 7075.1 lets a sole owner move that number to a corporation, but only if you formed the corporation and keep at least 51 percent ownership. It is a one way door. Once the number belongs to the corporation, it never converts back.

There is no equivalent path to an LLC. Form one and you apply for a brand new license number, and your fifteen years of history starts over at zero on paper. For contractors chasing public work or bigger GC relationships, that alone often settles the question.

When switching is not worth it

If your net profit is under roughly $60,000, the payroll costs, the $800 minimum, and the extra return usually eat most of the savings. Same if you are two or three years from winding down, since the cleanup has its own cost. The S corp is a volume tool: the more profit above a reasonable salary, the harder it works. It is not a starter move, and it is not automatic.
