When coverage is required
Colorado requires workers' comp for any business with employees working in the state, no matter how small. Part-time workers and family members count. If you have remote or traveling workers, look at where they actually work, not just where your office is.
Owners, contractors, and exceptions
Owner exclusions and independent contractor status need a separate check. Don't apply them to everyone in a small business. For construction, check the state's current rules before the job starts. Keep paperwork for every exclusion, and ask your insurer how excluded owners and subcontractors will be handled at audit.
If an employee is injured
Tell your insurer about any injury within 10 days, even if it seems minor. Deaths, or accidents that hurt three or more workers, need faster action. For non-emergency care, give the worker your list of approved medical providers as soon as they report the injury. Reporting an injury does not mean you agree the claim is valid.
Operating without coverage
Colorado can fine an uninsured employer up to $500 for each day without coverage and can shut the business down. If a worker is hurt while you have no coverage, you pay the claim yourself plus an extra 25% of the worker's benefits. Keep the WC 50 'Notice to Employer of Injury' poster up at all times.
How to arrange coverage
Buy coverage through an insurance agent. Pinnacol Assurance must offer coverage to Colorado employers. Ask about your provider list as well as price and payroll. Make sure supervisors know how to report injuries and choose doctors even when a manager is away.
Benefits and return-to-work planning
A work injury can lead to medical care, time off work, a lasting disability, or benefits for family members if a worker dies. Who qualifies, waiting periods, how wages are figured, and benefit limits all depend on state law and the facts of the claim. Ask your insurer which benefits it is looking at and what records it needs. Go by the doctor's work limits, not your own guess about what the worker can do. If you can offer lighter work, describe the duties and hours clearly and plan it with the doctor and your insurer.
Preparing an accurate cost estimate
Gather payroll by job and location, a description of each type of work, details on working owners, subcontractor records, and your past claims. Ask the insurer to confirm your job classes, how the rate is figured, any experience modifier, the minimum premium, fees, and audit terms. This site's calculator uses a base rate that you enter. It does not give a state-approved rate or a real quote. Compare offers using the same numbers, and track staff and work changes during the year so the final audit is easier.
Forms, posters, and notices

Weekly benefit limits
These limits cap the wage replacement checks an injured worker can get. Medical care is paid separately. Limits change every year, so check the source for the latest figures.
Colorado sets a new maximum weekly benefit every July 1. The 2026 order took effect July 1, 2026, and is linked from the Division's updates page.
Check a contractor’s coverage
Colorado has an online tool to check whether a business has a workers' comp policy.
Owner exemptions and elections
Corporate officers and LLC members who own at least 10% can reject coverage by filing a Rejection of Coverage form, on paper or online. This is for businesses with no other employees. If you already have a policy, ask your insurer which form it needs.
