Is Workers’ Comp Required in Colorado?
Yes, workers compensation insurance is required for all Colorado employers as soon as they have one or more employees, whether full-time, part-time, or seasonal, under C.R.S. Title 8, Articles 40-47
Colorado Workers’ Comp Requirements at a Glance
Here are the exact Colorado workers compensation requirements every employer should know:
| Employees that trigger the mandate | 1 |
| Which workers count | All employees count toward the threshold including full-time, part-time, seasonal, temporary, and family members; one employee of any type triggers the mandate; in the construction industry even sole proprietors and partners must carry coverage or file a formal rejection form with the Division |
| Who is exempt | Sole proprietors and general partners are not considered employees and are exempt by default but may voluntarily elect coverage; independent contractors (genuinely independent) are exempt; domestic or household workers are exempt if working fewer than 40 hours per week and fewer than 5 days per week; casual farm or ranch workers are exempt if paid less than 2000 per calendar year by that employer; casual maintenance or repair workers are exempt under the same 2000 per year threshold; real estate agents and brokers are exempt if compensated solely on commission |
| Owners & officers | Sole proprietors and general partners are already exempt by default and may voluntarily opt in; corporate officers who own at least 10 percent of the company and hold the title of president, vice president, secretary, treasurer, or chairman of the board may opt out by filing a notarized Form WC 43 (Rejection of Coverage) with the Division of Workers Compensation; LLC members who own at least 10 percent may also opt out via the same notarized Form WC 43; if the business has no other employees all officers or members may reject coverage but if other employees exist those employees must still be covered |
| Penalty for going without | First offense up to 250 per day for each day without coverage under C.R.S. 8-43-409; repeat offense up to 500 per day; the Director may issue a cease and desist order stopping all business operations until insurance is obtained; uninsured employers must pay 50 percent more in benefits to injured workers under C.R.S. 8-43-408 plus a 25 percent penalty on indemnity benefits; employer is personally liable for all workers comp benefits out of pocket; non-compliant employers may be required to post a bond; failure to maintain coverage for farm or ranch contract labor is a Class 2 misdemeanor under C.R.S. 8-40-302 |
| Monopolistic state? | No — buy from private carriers |
| State fund | Pinnacol Assurance is Colorado’s competitive state fund and insurer of last resort, required by statute to write coverage for any Colorado employer that applies and cannot decline on underwriting grounds; it is the largest workers comp insurer in the state covering over 57000 employers |
How to Get Workers’ Comp Coverage in Colorado

Private market: YES
What Workers’ Comp Covers in Colorado
Workers’ compensation is a no-fault system: an injured employee gets benefits without having to prove the employer did anything wrong, and in exchange gives up the right to sue for most workplace injuries. A typical Colorado policy pays for medical treatment tied to a work injury, part of the wages lost while the worker recovers, longer-term disability benefits if the injury is permanent, and death benefits to a family.
It also includes employers-liability coverage, which protects the business if an injury still leads to a lawsuit. That trade-off is the practical heart of the Colorado workers compensation requirements: the coverage exists to keep one bad injury from sinking both the worker and the business.
Employees vs. Independent Contractors in Colorado
The most common way owners get the Colorado workers compensation requirements wrong is by assuming a worker is an “independent contractor” who does not count. State agencies look at how the work is actually controlled, not the label on a 1099. If Colorado decides a contractor was really an employee, the business can owe back premiums and penalties as if coverage should have been in place all along.
When you are close to the employee threshold, confirm each worker’s status with your state board before you decide you are exempt.
Other Colorado workers’-comp rules: Construction carve-out — even otherwise-exempt sole proprietors and partners must have coverage or file a formal rejection if performing construction work and general contractors can be held liable for uninsured subcontractors under C.R.S.
8-41-404; the opt-out Form WC 43 for corporate officers and LLC members must be notarized; Colorado provides a real-time online verification tool for checking any employer’s workers comp compliance status; Colorado approved a 6.9 percent reduction in loss cost rates for 2026 marking the 12th consecutive year of decreasing rates
