Workers comp in Colorado starts at one employee. Seasonal counts.

Coverage explained·8 min read

The honest answer is that the day you hand somebody a rake and a paycheck, Colorado expects you to have a workers’ compensation policy in force. Not at five employees. Not at full-time. One person, on any schedule, related to you or not. Most of the contractors who call our workers compensation desk already know that in the abstract. What surprises them is how the rule treats the summer hire, the nephew, and the two guys who only show up when it snows. Here’s the statute, the fine, and what a small dirt or landscape outfit actually does about it.

What the law says

Colorado does not have a small-employer exemption for workers’ comp. The trigger is the first employee.

Colorado employers must carry workers' compensation insurance as soon as they have one or more employees, whether part-time, full-time, or family members (C.R.S. 8-40-203(1)(b), 8-44-101); the state can fine an uninsured employer up to $500 for every day without coverage. (C.R.S. 8-40-203(1)(b); 8-44-101; 8-43-409)

Read the middle of that sentence again: part-time, full-time, or family members. The Division of Workers’ Compensation put those words on its employer page because those are the three categories people try to argue out of. A part-timer is an employee. Your brother-in-law is an employee. The high school kid who mows on Saturdays is an employee.

The other thing the statute does is set the timing. Coverage has to be in force “at all times” while you have employees. The policy doesn’t start when you get around to it, or when the first payroll goes out. It starts before the first hour of work, which means the application, the bind, and the effective date have to happen before the crew does.

Where “seasonal” fits

Nowhere, and that’s the point. The word seasonal does not appear in the statute, and it doesn’t appear on the state’s employer page either. We’re not going to pretend it does. The rule counts employees, and it counts them while they’re working for you. A worker you pay for twelve weeks in the summer is an employee for twelve weeks, and the coverage requirement is live for those twelve weeks.

That matters more in Colorado than most places because so many crews in our trades run on a seasonal cycle. A lawn care and maintenance crew staffs up in April and thins out in October, and most landscaping contractors in Colorado run some version of that cycle. A plow operator has a driver list that only exists between the first storm and the last one. Excavation outfits above 9,000 ft lose weeks to frozen ground and hire back when it thaws. None of those cycles change the rule. The state doesn’t know your season. It knows whether somebody got paid.

Two practical consequences follow from that.

A policy that lapses over the winter is an uninsured employer in the spring. If you cancel in November to save the premium and hire the first mower back in April before the new policy is bound, you have an employee and no coverage. That’s the fine, and worse, that’s an injury with nobody paying for it but you.

Payroll estimates on a seasonal crew are honest guesses. Workers’ comp is rated on payroll, and the premium you pay up front is based on what you tell the carrier you’ll pay out over the year. A crew that runs six people in July and one in January is hard to estimate, and the audit at the end of the term is where the guess gets corrected. Better to guess honestly than low.

Who is not an employee

There are people on a job site who are not your employees, and the state does recognize that. Sole proprietors and partners are not employees of themselves by default. Corporate officers and LLC members can, under the state’s rules, elect out of coverage on their own bodies. In Colorado, a corporate officer or LLC member who owns at least ten percent of the corporation or company and controls, supervises, or manages its business affairs may elect to reject workers' compensation coverage by written notice on a Division-approved form sent by certified mail to the insurer (C.R.S. 8-41-202), while a working general partner or sole proprietor is not covered unless they elect to be included by endorsement as an employee of the insured (C.R.S. 8-40-302(5)(b)). (C.R.S. 8-41-202(1), (4); 8-40-302(5)(b)) A legitimate subcontractor with their own policy is not your employee.

The word doing the work in that paragraph is legitimate. The state and the carrier both look past the label to the facts: who controls the hours, who supplies the equipment, whether the person works for other contractors, whether they carry their own coverage. A laborer who shows up when you tell him to, runs your Yanmar mini skid steer, and has no other customers is an employee no matter what the check says. If you’re leaning on the subcontractor label to stay under the one-employee line, that’s the first thing an auditor will pull apart, and the audit article walks through exactly how they do it.

The fine, and the bigger problem

The fine is the part people quote. The trigger is 1 employee , and from that day forward the state can fine an uninsured employer up to $500 for each day without coverage. It can also order the work stopped until a policy is bound. When the Director of the Division of Workers' Compensation finds an employer in default of its insurance obligation, the Director must order the employer to cease and desist from business operations while the default continues, impose a fine for every day without coverage of not more than $250 for an initial violation and $250 to $500 for a second or subsequent violation, or both (C.R.S. 8-43-409(1)). (C.R.S. 8-43-409(1)(a), (1)(b)) On a job you meant to finish in a month, a stop order is expensive in a way the fine isn’t.

The bigger problem is the injury. Workers’ comp is a trade: the employer buys coverage, the injured worker gets medical care and wage replacement without having to prove fault, and in exchange the worker generally can’t sue the employer for the injury. An uninsured employer gets none of that trade. A back injury on a paver job, a hand in a chipper, a rollover on a wet cut near Bailey: without a policy, the bills and the lost wages are on you directly, and the protections the system gives an insured employer aren’t there. That’s the risk the statute is actually about.

Getting covered when nobody wants to write you

New contractors sometimes hear “no” from the private market. A one-year-old excavation outfit with no loss history and a payroll estimate that’s mostly hope is not every carrier’s favorite account. Colorado built a backstop for that.

Pinnacol Assurance, a state-created political subdivision that operates as a mutual insurer, may not refuse to insure any Colorado employer because of risk or premium size (C.R.S. 8-45-101(5)(f)), which is why agents call it the carrier of last resort. (C.R.S. 8-45-101(1), (5)(f)) [VERIFY]

In practice that has meant a Colorado employer has somewhere to get a policy when the private market says no, for as long as that rule stands. What we don’t control is what the private market will offer on a given day; that depends on your trade, your payroll, and your loss runs. What we do is shop the account and tell you straight which option is which, because the carrier of last resort and a private carrier can price the same crew differently, and the right answer changes as you build a history. The status of that state carrier is also in flux at the legislature, which is why the fact above carries a verify badge until the next session settles it.

What a small outfit actually does

Here’s what we tell every contractor who asks. Bind the policy before the first hire, not after. Estimate payroll honestly by class of work, because a landscaper who plows is rated differently in each season and the carrier needs both numbers. Decide up front whether the owners are in or out. Collect a certificate from every subcontractor before they start. Keep the payroll records by person and by task so the audit is a formality instead of a fight.

The crews that get this right treat the workers’ comp policy like the 811 ticket: something you set up before the machine unloads, not something you fix after.

What GCs and HOAs will ask for

Even if you somehow stayed under one employee, the market won’t let you work without the policy. Nearly every GC insurance exhibit and most HOA and property management contracts require workers’ compensation at statutory limits plus employer’s liability, and they ask for a certificate proving it. A snow contract on the plains east of Greeley is going to want it before the first storm. The article on reading a GC’s requirements covers the workers’ comp line on that exhibit, including the waiver of subrogation ask that usually rides along with it.

If you plow in winter and landscape in summer, the same policy has to cover both operations, and the seasonal combo article explains why that trips up the class codes.

Where to go from here

If you’re about to make your first hire, Get Insured starts with the crew: who they are, what they’ll run, and when they start, so the policy is bound before the first day. If you already have a workers’ comp policy and aren’t sure whether it’s rated right for a crew that changes with the season, that’s one of the first things we mark up in a policy review. The general liability page covers the other half of what a GC will ask you for.

FAQ

Questions contractors ask us

More questions, answered

Do I need workers comp in Colorado if I only have one part-time employee?
Yes. Colorado requires workers' compensation coverage as soon as you have one or more employees, and the Division of Workers' Compensation says that applies whether the employee is part-time, full-time, or a family member. The policy has to be in force from the first day they work, not from the first payroll. The workers compensation page covers what the policy does.
Does a seasonal worker count as an employee for workers comp?
The statute never uses the word seasonal, and it doesn't need to. A seasonal worker is an employee for the weeks you pay them, so the coverage requirement applies for those weeks. The summer mowing hire, the guy you bring on for plow season, and your cousin who runs the skid steer in October are all employees while they're on the clock.
What happens if I get caught without workers comp in Colorado?
The state can fine an uninsured employer up to $500 for every day without coverage, and it can shut the job down until a policy is bound. Separately, an injured worker's medical bills and lost wages become your problem directly, with none of the protections the workers comp system gives an insured employer. The fine is the smaller of the two risks.
Can I pay a helper as a 1099 subcontractor and skip workers comp?
Calling someone a subcontractor doesn't make them one. The state looks at how the work actually happens (who sets the hours, who owns the tools, whether they work for anyone else), not what the check says. A laborer you direct every morning is usually an employee, and at audit the carrier will treat uninsured subs the same way. Get a certificate from every real sub.
