I get this question constantly: do I actually need workers' comp if I'm the only employee? Here is the short answer. If you have W-2 employees, you are almost certainly required to carry it. If you are solo with no payroll, you can usually elect out, though a few high-risk trades and states still require coverage. The workers comp cost contractors face in 2026 sits right alongside payroll taxes and wages as a major labor expense. For the full picture, see our guide to hiring, payroll, and labor costs. Workers' compensation is state-mandated insurance, not a federal tax. It covers medical bills and lost wages when someone is injured on the job. You pay the premium. If you have employees and no coverage, you are personally on the hook for those bills. If you are solo, the rules loosen, but the risk does not disappear.

When are contractors legally required to carry workers' comp?

With W-2 employees, you are almost certainly required to carry workers' comp. Solo contractors with no employees can usually elect out, though a few high-risk trades require coverage regardless of employee count. The threshold varies by state. California mandates coverage at one employee under Labor Code §3700. A handful of states allow two or three employees before the requirement kicks in. Once you hire payroll labor, the state expects a policy in place.

The 1099 subcontractor question is where the line blurs. If your subcontractors are truly independent — they control how the work is done, use their own tools, and carry their own insurance — they generally need their own policy. If they are misclassified employees, their injury claim lands on you. The same factors that trigger a 1099 vs W-2 audit also determine who pays for a jobsite injury. Before you hire, it is worth reading how employees compare to 1099 subs for your total labor cost.

How much does workers' comp cost?

Most contractors pay anywhere from a few hundred dollars for a solo minimum premium to thousands for a crew with significant payroll. The exact number comes from three variables. You pay a state-set class code rate. The insurer multiplies that rate by each $100 of payroll, then adjusts the result by your experience modification factor. A carpenter or roofer sits in a high-risk class code — NCCI codes like 5403 or 5551 — so the per-payroll multiplier is larger than for a clerical worker under code 8810. Your experience mod reflects your claims history; the National Council on Compensation Insurance (NCCI) calculates it in most states by comparing your actual claims to expected claims for your class code. A clean record pushes the multiplier below 1.0. Past claims push it higher.

Here is how the math works. Say you run $100,000 in annual payroll. Divide by 100 to get 1,000. Multiply by your state-published class code rate for your trade. Multiply again by your experience mod. If your mod is 0.90, the premium is 1,000 × rate × 0.90. The insurer will audit at year-end and reconcile that payroll figure against your quarterly Form 941 wages. If your actual payroll was higher, you get a bill for the difference.

For context, you already pay 7.65% FICA on wages. The Social Security piece stops at the $184,500 wage base. That cap means a worker earning above that amount stops accruing Social Security tax for the year, though Medicare continues. Federal and state unemployment taxes sit on top of that. Workers' comp is another layer of labor cost, which is why the true cost of an employee always runs higher than the hourly wage alone.

What happens if you skip required coverage?

You face daily fines, stop-work orders, and personal liability for an injured worker's full medical bills and lost wages. The penalty is state-specific and escalates fast. Many states issue fines per day of noncompliance. Some will shut down your jobsites until you produce a certificate of insurance. If an uninsured worker is injured, you are personally responsible for the medical bills and wage replacement. In some states, the lack of coverage also strips away your legal defenses if the worker sues, meaning you could face uncapped damages.

Audits in this context are routine. State insurance funds and departments of labor regularly cross-check payroll records against active policies. A mismatch generates a letter. It is manageable, but ignoring it is expensive.

Does being an S-corp or LLC change the rule?

Yes. In many states, corporate officers and LLC members can file an exclusion form to opt out of coverage. But if your S-corp pays you W-2 wages, a few states automatically count you as an employee unless you actively elect out. The form is usually one page, but it must be filed with the insurer and sometimes with the state.

If you are unsure whether your structure triggers the requirement, the state insurance department website is the authoritative source. Do not rely on a forum post from 2019. Rules change, and the exclusion form you need for 2026 may have a new edition.

The entity choice also affects how you deduct the premium. For more on that, see our breakdown of LLC vs S-Corp for contractors.

Is the premium tax-deductible?

Yes. Workers' comp premiums are an ordinary and necessary business expense under IRC §162(a), fully deductible on your business return. If you are a sole proprietor, the deduction flows through Schedule C and reduces both your federal income tax and your self-employment tax base. For an S-corp, the corporation deducts the premium before the profit passes through to your K-1.

That deduction partially offsets the out-of-pocket cost. It does not make the insurance free, but it does mean the after-tax price is lower than the headline premium. For a fuller list of what else you can write off, see our contractor tax write-offs checklist.

How do you shop for a policy as a small contractor?

Start by confirming your exact class code with your state rating bureau, then request quotes from private carriers and the state fund. Using the wrong code — say, a clerical code for a framing crew — can void a claim. If private carriers decline you, the state assigned-risk pool will issue a policy, though the rate is usually higher.

Ask about pay-as-you-go billing. Instead of paying a large estimated premium upfront and reconciling at year-end, you pay a calculated amount after each payroll run. That smooths cash flow and reduces the risk of a surprise audit bill. Keep clean payroll records either way. The insurer will audit, and discrepancies between your books and your 941s trigger back-charges.

Should you carry workers' comp even when it's optional?

It depends on your trade, your health coverage, and whether your clients require a certificate of insurance. If you are a solo handyman with a good health plan and no employees, self-insuring the risk may be mathematically sensible. If you are a roofer or framer, or if your health insurer excludes occupational injuries, one bad fall can cost more than a decade of premiums. The premium buys you wage replacement, not just medical coverage, and most disability policies exclude work-related injuries.

Clients and general contractors also matter. Many commercial jobs and government contracts require a certificate of insurance before you step on site. Going bare may cost you the job, not just expose you to liability.
