Hiring employees in Colorado: the 2026 compliance checklist for employers and recruiters

As of October 2026, an employer hiring in Colorado has to register for an unemployment insurance account, register with the FAMLI paid leave program and collect premiums from each worker as soon as they are hired, carry workers' compensation insurance from the first employee, put compensation, benefits and an application deadline in every job posting at any employer size, keep age, criminal history and pay history questions off the initial application, give each new hire the FAMLI Required Program Notice, and report the hire to the Colorado State Directory of New Hires within 20 calendar days. Colorado is a one-party consent state for recording, limits credit checks, and its rules on automated hiring decisions take effect January 1, 2027.

The Colorado hiring checklist at a glance

What must be in place before the first Colorado hire?

Three things. CDLE's new employer checklist says employers pay unemployment insurance premiums and file quarterly wage reports, with the account opened online through MyBizColorado. The FAMLI Division says "All businesses with at least one qualified employee are required to register with the FAMLI Division in My FAMLI+ Employer." Its published premium is 0.88% of wages, split 0.44% employer and 0.44% employee, and businesses with nine or fewer employees send in 0.44% of wages. Its small business guide says premiums are collected from each worker "as soon as they are hired," full-time or part-time.

Third, workers' compensation. CDLE's Division of Workers' Compensation says "If you have one or more employees working for you in Colorado, you must have workers' compensation insurance," whether they are part-time, full-time or family, and the premium cannot be deducted from wages. The federal layer (an EIN, Form W-4 and Form I-9 by the third business day) applies on top.

Does a staffing or recruiting agency need a Colorado license?

Not a general one. As of October 2026 we found no Colorado statute licensing employment agencies, temporary staffing firms or employer-paid search firms. What applies instead, in Title 8 and the criminal code: fee and refund rules for agencies that charge job seekers, CDLE certification for health care staffing agencies, annual certification for professional employer organizations, and a specific unemployment insurance notice rule for temporary staffing firms. See Colorado staffing agency rules.

What must a Colorado job posting include, and can you ask about pay history or age?

Colorado's posting rules are the broadest of any state we cover. Under the Equal Pay for Equal Work Act, every employer with at least one employee in Colorado, of any size, must disclose compensation, benefits and an application deadline in each posting, and give current employees notice of most openings before selecting a candidate. See the Colorado pay transparency guide.

The same act, at C.R.S. 8-5-102(2), bars asking about pay history and relying on it to set pay, with no size threshold and no carve-out for a number the candidate volunteers; see the Colorado salary history ban. And since July 1, 2024, the Job Application Fairness Act (SB 23-058, C.R.S. 8-2-131) bars asking about age, date of birth, or dates of school attendance or graduation on an initial application. An employer that asks for transcripts or certifications must tell applicants they may redact information that identifies their age. CDLE enforces it with warnings and compliance orders, and civil penalties for repeat violations.

When can you ask about criminal history or run a credit check?

Not on the initial application. The Colorado Chance to Compete Act, C.R.S. 8-2-130 (HB 19-1025), has applied to all private employers, their agents and employment agencies since September 1, 2021. It bars ads saying people with a criminal history may not apply, the same statement on application forms, and criminal history questions on the initial written or electronic application. It expressly lets an employer obtain a publicly available background report at any time. See Colorado's ban-the-box law.

Credit checks are limited by the Employment Opportunity Act, C.R.S. 8-2-126: no use of consumer credit information for employment purposes unless it is substantially related to the job, with exceptions for banks and financial institutions, reports required by law, and listed executive and fiduciary roles. Applicants may explain mitigating circumstances, and reliance must be disclosed before an adverse decision. Our credit check laws guide compares other states.

Can you record or transcribe a job interview in Colorado?

Yes, as a participant. Wiretapping under C.R.S. 18-9-303 applies to "any person not a sender or intended receiver" of a call who records it without the consent of a sender or receiver, and eavesdropping under 18-9-304 applies to "any person not visibly present" who records without a principal party's consent. An interviewer on the call or in the room is outside both. Our Colorado recording consent guide covers the detail, and recording calls across state lines covers candidates in all-party states.

Does Colorado regulate AI in hiring?

Yes, from January 1, 2027. Senate Bill 26-189, signed May 14, 2026, repealed the 2024 Colorado AI Act before it took effect and replaced it with rules on automated decision-making technology in consequential decisions. An employer or agency doing business in Colorado that uses such a tool to materially influence a hiring decision will owe the candidate a notice before use, a disclosure within 30 days after an adverse outcome, a way to correct inaccurate data and a chance at human reconsideration, and must keep records for three years. The old law's risk management program and annual impact assessments are gone. See Colorado's AI law for employers and AI hiring laws by state.

Does Colorado require E-Verify?

No. As of October 2026, Colorado has no E-Verify mandate for any employer. Its public contract rule, Article 17.5 of Title 8, was repealed effective July 1, 2022. What remains is a state power to audit employers' Form I-9 compliance and a duty for CDLE to tell employers E-Verify is available and optional. See E-Verify requirements in Colorado.

Which state withholding form does a new hire complete?

Usually just the federal W-4. The Department of Revenue's DR 0004, Colorado Employee Withholding Certificate, is optional for employees; if an employee does not complete one, the employer calculates Colorado withholding from the federal W-4. If an employee does hand one in, the employer must calculate Colorado withholding from the amounts entered on it.

Which notices must a new Colorado employee get at hire?

• FAMLI Required Program Notice. The FAMLI Division says to "Share FAMLI's Required Program Notice with every new employee," and that an internal summary or handbook excerpt is not enough. The notice must also be posted in English, Spanish and any language spoken by at least 5% of the workforce, sent to remote employees by email or intranet, and given again within five days of learning of a qualifying life event. Penalties run up to $500 per violation.
• Workers' compensation poster. CDLE lists displaying the Notice to Employer of Injury poster (WC 50) "at all times" among every insured employer's duties.
• Non-compete notice, if any. A permitted non-compete is void unless the candidate gets a separate, signed notice of it before accepting the offer, and presenting a void covenant carries a $5,000 penalty per worker. See Colorado non-compete law.

How do you report a new hire in Colorado?

To the Colorado State Directory of New Hires. Colorado Child Support Services says "Employers must report any new hire within 20 calendar days of the hire," and if the first scheduled payroll falls after that window, the report can go in then. It needs the employee's name, address, Social Security number, date of birth and first day worked for wages, plus the employer's payroll address and FEIN. Independent contractors should be reported if they give the employer a Social Security number. Reports are filed online through the State Directory of New Hires portal.

The Colorado hiring steps in order

1. Before the first hire: open the unemployment insurance account through MyBizColorado, register with FAMLI, and bind workers' compensation coverage.
2. Posting: compensation, benefits and an application deadline in every posting, and notice of the opening to current employees; no "no criminal records" language.
3. Application: no questions about age, school dates, criminal history or pay history; offer redaction if you ask for transcripts.
4. Interview: a participant may record; ask first if the candidate is in an all-party state. Plan the 2027 automated-decision notices if a tool scores candidates.
5. Offer: any non-compete goes with a separate signed notice before acceptance; credit checks only where substantially job-related.
6. First day: Form I-9, W-4 (and DR 0004 if the employee wants it), and the FAMLI Required Program Notice.
7. Within 20 calendar days: report to the State Directory of New Hires; FAMLI premiums are collected from the start of employment.
