Workers Comp Insurance for Small Business: Costs

1. Introduction

Quick Answer: There is no single price here. Insurers set a rate per $100 of payroll for each class of work, then multiply by your payroll and adjust for your state and claims record. Two employers with the same headcount can pay ten times apart.

Ask five owners what they pay and you will get five answers that sound irreconcilable. They are not. They are the same formula with different inputs, and the inputs are all knowable before you ever request a quote.

So this page works the way an underwriter does. It starts with the rate per $100 of payroll for real trades, shows what each state adds or removes, then uses federal data to explain why this one policy has been getting cheaper while everything else on your renewal has not. DollarVisor takes no payment for placement, so nothing below is pushing you toward an insurer. It sits inside our guide to the types of insurance and which ones you actually need.

2. What Workers Comp Actually Pays For

Quick Answer: Workers comp pays an injured employee’s medical bills and part of their lost wages, with no argument about fault. In exchange, the employee normally gives up the right to sue you over the injury. That trade is the whole point of the policy.

The bargain is old and simple. The worker gets paid quickly without proving you did anything wrong, and you get protection from a lawsuit that could otherwise reach your business assets. Texas is the outlier: employers there who drop coverage drop that legal shield too, and the state warns that coverage limits liability if an employee sues, per the Texas Department of Insurance.

What the policy does not do catches owners out:

• Not customers or the public. A visitor slipping in your shop is a liability claim, which is what general liability cover is written for.
• Not contractors, usually. Genuine independent contractors sit outside the policy, though states police that line hard and reclassify at audit.
• Not owners, by default. Sole proprietors, partners, and many corporate officers are excluded unless they elect in.
• Not off-the-job injury or illness. That is what disability insurance and health insurance are for.

3. What Workers Comp Costs by Trade

Quick Answer: Premium equals your rate per $100 of payroll, times your payroll, divided by 100. On $250,000 of payroll, a modeled clerical office lands near $400 a year and a modeled roofing crew near $56,000. The gap is about 140 to 1.

Nothing else in your insurance file swings this wide. Rates are set by class code, and the class code describes the work, not the revenue. That is why headcount and payroll drive the bill while turnover barely registers, and why this policy behaves so differently from the rest of the cover a small business carries.

Move one worker from the office class into the roofing class and the premium on their wages rises roughly 140-fold. Nothing else on your renewal behaves like that.

The practical reading: split your payroll properly. If your office manager also spends two days a month on site, some states let you split their wages across two class codes and some do not. Getting that split wrong is the most expensive filing error an employer can make here.

4. What Your State Does to the Price

Quick Answer: Oregon’s biennial state study puts Hawaii top at $2.52 per $100 of payroll and North Dakota bottom at $0.50, a five-fold spread on identical work. New York sits at $1.98, California at $1.86, Texas at $0.78, and Ohio at $0.68.

The most useful public number in this market comes from a state government rather than an insurer. Oregon’s Department of Consumer and Business Services prices one standard mix of industries in every state and publishes the result as an index rate per $100 of payroll in its workers compensation premium rate ranking by state. No comparable public table exists for general liability pricing, which is part of why comp is the easier of the two to benchmark.

A contractor working three states is therefore running three premiums for one crew, and the cheapest state to hire in is often not the cheapest state to sell in. Ohio and North Dakota are also monopolistic states, where cover comes from a state fund rather than a private insurer, so shopping around is not an option there.

5. When Coverage Becomes Compulsory

Quick Answer: Most states require workers comp from the first employee. A minority set a threshold of three, four, or five. Texas is the only state where private employers can decline coverage entirely, and Florida requires it from employee one in construction but employee four everywhere else.

Thresholds catch owners out because of how the counting works. Part-timers usually count, and family members often do. In Florida, corporate officers and LLC members count toward the total, and any construction employer with one or more workers must hold a Florida policy, per the Florida Division of Workers’ Compensation.

Texas sits on its own. Employers there may go without, but they become registered non-subscribers, must report lost-time injuries to the state, and lose the policy’s legal protections. That leaves them leaning on a liability policy never written to answer an employee injury.

6. Why This One Policy Keeps Getting Cheaper

Quick Answer: Federal price data shows workers comp premiums fell every year from 2019 to 2026, down 11.7% over the period and 7% below their June 1998 level. While liability and property lines have repriced upward, this one has drifted down.

The Bureau of Labor Statistics tracks what insurers actually charge by line through the Producer Price Index. The workers compensation series is the only major commercial line still sitting below its 1998 base.

That is seven consecutive annual declines. Set against it, our page on what general liability costs a small business shows the liability line rising 8.7% in a single year. Same renewal envelope, opposite directions.

7. The Injury Data Behind the Falling Prices

Quick Answer: Private employers reported 2.5 million injury and illness cases in 2024, the lowest since the series began in 2003, at a rate of 2.3 cases per 100 full-time workers. Fewer claims mean lower rates, and that is why comp prices keep drifting down.

Premiums follow claims with a lag of two or three years, so the injury numbers are the leading indicator for your next renewal. Nothing on the rest of your insurance stack gives you that kind of advance warning. The federal survey shows the direction clearly.

Claims still hurt when they land, though. The median case involving days away from work cost the employee eight days, and cases involving job transfer or restriction ran to a median of 15 days. One serious claim then sits on your experience record for three policy years.

8. The Experience Mod, Explained Simply

Quick Answer: The experience modification factor is a multiplier applied to your premium once your payroll is large enough to qualify. A mod of 1.00 is average, 0.85 is a 15% discount, and 1.25 is a 25% surcharge. It is built from your last three complete policy years, excluding the current one.

Take the modeled Georgia landscaper from the tables above, at roughly $13,000 of base premium. Apply the three mods and the arithmetic is blunt:

• Mod 0.85. Premium falls to about $11,050, a saving of $1,950 a year for a clean record.
• Mod 1.00. Premium stays at $13,000, the industry average outcome.
• Mod 1.25. Premium rises to about $16,250, and the extra $3,250 repeats for three years.

The mod counts claim frequency more heavily than claim size, which surprises most owners. Three small strains hurt your factor more than one large but isolated injury, because insurers read frequency as a control problem rather than bad luck. It works nothing like the flat pricing on a commercial auto policy, where one bad crash dominates the file.

9. Five Ways to Cut the Premium Without Cutting Cover

Quick Answer: Audit your class codes, report payroll accurately, run a return-to-work program, ask about a pay-as-you-go plan, and close old claims. Each attacks a different part of the formula, and none of them reduces what an injured employee is owed.

1. Audit the class codes. A supervisor coded as a roofer can cost thousands a year on their wages alone.
2. Report payroll accurately. Under-reporting produces an audit bill you cannot budget for; over-reporting finances the insurer all year.
3. Run a return-to-work program. Light duty converts a lost-time claim into a medical-only claim, which rating systems weight far more kindly.
4. Ask for pay-as-you-go billing. Premium is calculated from real payroll each cycle, removing the deposit and the audit surprise.
5. Chase open claims closed. Old claims sitting on high reserves inflate your mod until they are settled and revalued.

Chasing the lowest headline number backfires here. A cheap policy built on the wrong class codes fails at audit, and the corrected bill arrives long after you spent the saving.

10. Conclusion

Workers comp insurance for small business is one formula with four inputs: the class rate for the work, the payroll it applies to, the state you operate in, and your own experience modification. Identify which input moved and you stop guessing at your renewal.

Carry three anchors into that conversation. Rates run from roughly $0.16 per $100 of payroll for office work to $22 or more for roofing. States range from $0.50 to $2.52 for identical work. And the market has cut prices seven years running, so an increase on your desk almost certainly came from inside your own business.

11. Workers Comp Insurance for Small Business FAQ

How much is workers comp insurance for a small business?

It follows payroll and trade, not headcount. On $250,000 of payroll, a modeled office employer lands near $400 a year and a modeled roofing employer near $56,000. Most retail and food businesses sit between $2,500 and $4,000.

Is workers comp based on payroll or number of employees?

Payroll. Insurers set a rate per $100 of payroll for each class of work, then multiply. Headcount matters only because it moves payroll and because state coverage thresholds are counted in employees.

Which states require workers comp insurance?

Nearly all of them, most from the first employee. Texas is the only state where private employers can decline coverage, and a handful of others set thresholds of three, four, or five employees first.

Does workers comp cover the business owner?

Not automatically. Sole proprietors, partners, and many corporate officers are excluded by default and must elect in. Electing in adds their wages to the rated payroll and raises the premium.

Why did my workers comp premium go up when national rates are falling?

Almost always payroll growth or your experience modification factor. National premiums fell 11.7% between May 2019 and May 2026, so a rise on your renewal points to something specific in your file.

What happens if a small business has no workers comp insurance?

Penalties vary by state but commonly include fines, stop-work orders, and personal liability for the employee’s medical costs and lost wages. That exposure usually dwarfs the premium.
