Staffing agency license in Colorado: no general license, but rules apply

Colorado does not issue a general license for employment agencies, temporary staffing firms or employer-paid search firms. I found no current statute that requires one as of October 2026. That does not leave the state unregulated. Agencies that charge job seekers face fee and refund rules in the criminal code, health care staffing agencies must certify with the Colorado Department of Labor and Employment (CDLE), professional employer organizations need an annual certification, and temporary staffing firms have a specific unemployment insurance notice rule.

This page covers each of those, plus the ordinary employer registrations a Colorado staffing firm needs. For how Colorado compares with states that license agencies outright, see employment agency license requirements.

The short answer by business model

Agencies that charge job seekers: C.R.S. § 18-5-307

Colorado regulates fee-charging agencies through a section of the criminal code on fraud, published in Title 18. It applies to private employment agencies where an applicant may become liable for a fee, and to sellers of job lists that charge applicants more than $20 per 30 days. The main rules:

• Written contract. Any fee must be under a written contract that sets out refund and extended payment terms, or says plainly that those options are excluded.
• No fee before placement. The statute says no fee shall be charged until the applicant is placed.
• Short jobs. If the job ends within 100 days, the applicant owes no more than 1 percent of the total fee for each day worked.
• Refund timing. Refunds are due within seven days of written notice that the job ended, and a late refund makes the agency liable for double the amount.
• Advertising. Ads must identify the business as a private employment agency, and the statute lists prohibited acts including advertising fictitious jobs and misleading "fee-paid" claims.

A knowing violation is a class 2 misdemeanor. Violations involving three or more applicants in a year make the agency a public nuisance, and an agency convicted under the section must then file a $20,000 cash or surety bond with CDLE and keep it for as long as it does business in Colorado. CDLE's role here is to hold that bond, not to license agencies.

None of this applies to a firm paid only by employers. Employer-side fees, including temp-to-perm conversion fees outside health care, are set by contract; see temp-to-perm conversion fee for how those clauses are usually written.

Health care staffing agencies: certification required

The one place Colorado requires a staffing firm to register before it operates is health care. Under C.R.S. § 8-4-125, added by Senate Bill 22-210 and amended in 2023, it is unlawful to operate a health care staffing agency without initial and annual certification with CDLE. Certified agencies file reports twice a year, due April 30 and October 31, and late or deficient reports draw escalating fines of $500, then $10,000, then $20,000.

The section also limits conversion fees. A health care staffing agency may not charge fees or liquidated damages when a facility permanently hires a licensed or certified nursing professional the agency placed, except charges for the first 30 calendar days of the placement. A facility or worker harmed by a violation can sue for damages, up to $5,000 per violation, and attorney fees. If you staff nurses into Colorado facilities, write your client agreement around this limit rather than a standard conversion clause.

PEO certification

Professional employer organizations are certified by CDLE under C.R.S. § 8-70-114, part of the Colorado Employment Security Act. A business may not use the name "professional employer organization" or "PEO," or provide PEO services, without certification. Certification is annual, renewed on or before June 30, and includes an independent opinion of counsel. The fee is set by CDLE rule and the statute caps it at $500; I could not confirm the current amount from a CDLE page.

Each year the PEO must also meet one of three financial security options: a surety bond, cash deposit or letter of credit equal to 50 percent of the prior year's unemployment insurance premium; an audited financial statement showing at least $100,000 in working capital; or accreditation by an approved assurance organization. Penalties include probation, fines of up to $1,000 per material violation, and losing the right to report unemployment contributions for clients. A conventional temporary staffing firm is not a PEO and does not need this certification.

Temporary staffing and unemployment insurance

C.R.S. § 8-73-105.5 is aimed squarely at temporary help firms. If the firm gives each worker written notice at hire that they must contact the firm for a new assignment when one ends, a worker who does not do so may be treated as having quit for unemployment purposes. The notice only protects you if it is given at hire and you can prove it, so make it a signed page in your onboarding packet.

Employer registrations every Colorado staffing firm needs

• Workers' compensation. Required for any employer with one or more employees under C.R.S. § 8-40-203. A temp firm is the employer of the people it places, so coverage starts with the first shift; see staffing agency insurance requirements.
• Unemployment insurance. Open an employer account with CDLE's Division of Unemployment Insurance. Liability generally begins once you pay $1,500 in wages in a calendar quarter or employ someone in 20 weeks of a year.
• Business and tax registration. Entity filing with the Secretary of State and a wage withholding account with the Department of Revenue. The setup sequence is in how to start a staffing agency.
• Pay transparency. Colorado's job posting rules apply to postings you write for clients and for your own staff. See pay transparency law in Colorado.
• Farm labor contractors. These register with CDLE under C.R.S. §§ 8-4-115 to 8-4-119, a separate track from anything above.

Colorado's lack of a general license is easy to over-read. Re-check if you add health care staffing, start co-employing a client's own staff, or begin charging candidates, because each of those moves you into a regime that does require a filing.
