Choosing a PEO in Colorado
Colorado has built one of the most comprehensive employee protection frameworks in the Mountain West, with a minimum wage of $15.16 per hour as of 2026. Colorado's COMPS Order (Colorado Overtime and Minimum Pay Standards) governs overtime, minimum wage, and other wage and hour requirements for most private Colorado employers — with specific provisions that differ from the federal FLSA in important ways, including a daily overtime threshold of 12 hours in addition to the standard 40-hour weekly threshold.
Colorado launched its Family and Medical Leave Insurance (FAMLI) program in 2024, providing employees with up to 12 weeks of paid family and medical leave per year — and up to 16 weeks for pregnancy-related conditions. FAMLI is funded through small premiums split between employers and employees and provides a meaningful benefit that Colorado businesses can now offer through a PEO-administered payroll system. Colorado also has a strong pay transparency requirement, mandating that employers include salary ranges, benefits, and other compensation details in all job postings.
Colorado requires employers to provide paid sick leave under the Healthy Families and Workplaces Act (HFWA) — up to 48 hours of paid sick leave per year for most employees, with additional public health emergency leave provisions. Colorado follows the federal WARN Act, requiring 60 days advance notice for layoffs affecting 50 or more employees. Colorado is not a right-to-work state, and its labor market — particularly in Denver and the Front Range — is highly competitive.
Colorado's economy is driven by technology, aerospace, outdoor recreation, healthcare, and energy — industries with diverse and demanding HR needs. The state's strong employee protections, including FAMLI, paid sick leave, pay transparency, and daily overtime requirements, create a compliance environment where dedicated HR expertise is essential. A PEO with Colorado expertise can manage the full range of state-specific requirements while providing access to the competitive benefits packages needed to attract talent in Colorado's tight labor market.

Frequently Asked Questions
What is the minimum wage in Colorado in 2026?
Colorado's minimum wage is $15.16 per hour as of 2026, adjusted annually based on a set formula. Colorado's COMPS Order governs overtime and minimum wage for most private employers, including a daily overtime threshold of 12 hours in addition to the standard 40-hour weekly threshold. Tipped employees and agricultural workers are subject to different rules under COMPS.
What is the Colorado FAMLI program?
Colorado's Family and Medical Leave Insurance (FAMLI) program provides employees with up to 12 weeks of paid family and medical leave per year — up to 16 weeks for pregnancy-related conditions. The program is funded through premiums split between employers and employees. Benefits are paid directly to employees by the state, with leave paid at 90% of wages up to a cap.
Does Colorado require paid sick leave?
Yes. Colorado's Healthy Families and Workplaces Act (HFWA) requires most Colorado employers to provide up to 48 hours of paid sick leave per year. Employees accrue 1 hour of leave per 30 hours worked. The law also includes additional paid public health emergency leave provisions. A PEO can administer HFWA-compliant paid sick leave as part of their HR services.
What are Colorado's pay transparency requirements?
Colorado requires employers with at least one Colorado employee to include the hourly rate or salary range, a general description of benefits, and other compensation in all job postings — including remote positions that could be filled by a Colorado resident. Violations can result in fines of $500 to $10,000 per posting. A PEO can help businesses design compliant job posting templates and compensation structures.
