Let’s call him Marco. Marco ran a small electrical contracting business out of El Cajon. He had a core crew of four guys he called whenever a job came in: a licensed electrician, two helpers, and a low-voltage tech he’d been working with for six years.

Marco paid them regularly, kept a loose schedule, and considered them part of the team. To make things simple, he ran them through payroll, withheld taxes, and issued W-2s at the end of every year.

It felt like the right thing to do. It was not.

After a routine payroll audit, the California Employment Development Department (EDD) took a close look at Marco’s records. What they found triggered an IRS referral. The four workers Marco had been treating as employees were, under both California and federal standards, properly classified as independent contractors. He had been over-withholding, over-paying payroll taxes, and in some cases creating paperwork liability that didn’t need to exist.

The result: amended returns, penalty abatement negotiations, and months of headaches that a single classification review could have prevented.

Wait, Can You Over-Classify Workers? Isn’t That the Safe Choice?

Most business owners assume the risk only flows one way: that calling someone a 1099 when they’re really an employee is what gets you in trouble. And that’s true, that mistake is common and expensive.

But the reverse happens too. Treating independent contractors as employees creates its own set of problems:

• You’re paying employer-side FICA taxes you don’t owe
• You may be filing incorrect payroll tax returns (Forms 941, 940)
• You could be setting up future workers’ comp and unemployment liability you don’t need
• The workers themselves may owe back taxes on over-withholding, triggering amended 1040s
• California’s EDD can assess back UI contributions and penalties from their side

In Marco’s case, the over-classification wasn’t catastrophic, but fixing it cost several thousand dollars in CPA fees, amended returns, and penalty deposits. All avoidable.

The Real Standard: How California and the IRS Classify Workers

California uses one of the strictest worker classification tests in the country: the ABC Test, established under AB 5 and codified in Labor Code Section 2775. To treat someone as an independent contractor in California, you must be able to prove all three of the following:

The IRS uses a separate multi-factor “Common Law” test that looks at behavioral control, financial control, and the type of relationship. In practice, the California ABC Test is stricter. If a worker qualifies as an independent contractor under California law, they almost certainly qualify federally too.

For trades businesses specifically, Prong B is the landmine. If your business does electrical work and you hire an electrician to do electrical work, you have a problem calling them a 1099, even if everything else looks clean.

The Penalty Math: What Misclassification Actually Costs

Whether you’re over-classifying or under-classifying, the IRS and EDD have teeth. Here’s a look at what’s typically on the table:

In Marco’s case, the over-withholding meant he had been remitting extra money to the IRS unnecessarily. Getting it back required amended 941s, a refund claim process, and documented proof that each worker met the independent contractor standard. Not impossible, but time-consuming and billable.

The Comparison: Employee vs. Independent Contractor in Trades

What Marco Should Have Done (And What You Should Do Now)

The good news is this is completely preventable with a proper classification review before you run your first payroll or issue your first check. Here’s the basic process:

1. Map your workforce. List every person who does work for your business. Note how often, what they do, and how you pay them currently.
2. Apply the ABC Test to each person. Be honest about each prong, especially Prong B. Don’t assume the answer.
3. Document the contractor relationship. If someone qualifies as a 1099, use a written independent contractor agreement that reflects the true nature of the work. They should have their own business, their own tools, and the ability to work for others.
4. Collect a W-9 before any payment. No exceptions. You need this to issue a 1099-NEC correctly.
5. File 1099-NECs correctly and on time. January 31 is the deadline for recipients and the IRS. Missing it triggers penalties.
6. Review annually. Worker relationships evolve. A 1099 who starts working 40 hours a week exclusively for you may have crossed into employee territory.

California Adds Another Layer: CSLB and Licensing Exposure

For San Diego contractors specifically, worker misclassification isn’t just a tax problem. The California Contractors State License Board (CSLB) actively investigates unlicensed work performed by improperly classified contractors. If you’re calling someone a 1099 sub but they don’t hold their own valid C-10 electrical license, you may be creating unlicensed contractor liability on top of your payroll exposure.

That’s a separate enforcement action entirely, and one the CSLB takes seriously in San Diego County.

When Employee Classification Actually Makes Sense

To be clear: there are plenty of good reasons to hire employees. If you have workers who show up daily, use your trucks and tools, work exclusively for you, and are doing the core work of your electrical business, they may well be employees under any honest analysis. Running them as W-2 employees in that scenario isn’t wrong. It’s correct.

The mistake Marco made wasn’t necessarily choosing W-2. The mistake was not asking the question deliberately and instead defaulting to payroll because it felt like the responsible choice.

Worker classification should always be a deliberate decision, not a default.

Bottom Line for San Diego Electricians and Trades Owners

Marco’s story is not unusual. Across North County San Diego, from Carlsbad to Escondido to El Cajon, small electrical, plumbing, HVAC, and general contracting businesses are navigating exactly this issue. The EDD is well-funded and California takes misclassification enforcement seriously on both sides of the line.

If you haven’t had a formal worker classification review for your business, that’s the place to start. A good CPA with trades industry experience will go through your workforce, apply the correct tests, and give you a defensible, documented position, before an auditor does it for you.
