Colorado Pay Equity Law: Postings, Penalties, and Safe Harbor

The Colorado pay equity law, formally the Equal Pay for Equal Work Act, requires every employer in the state to pay workers equally for substantially similar work regardless of sex, publish salary ranges and benefits in job postings, notify employees of internal openings, and keep pay records. It took effect January 1, 2021, and was amended in 2024 to tighten rules for remote jobs and promotion notices. Transparency violations carry fines of $500 to $10,000 each. Discriminatory pay triggers back wages and, usually, an equal amount in liquidated damages on top.

Which Employers Are Covered

The statute defines “employer” as the state, its political subdivisions, departments, institutions, and school districts, plus “every other person employing a person in the state.”¹ There is no minimum headcount. A one-person Colorado operation is covered on the same terms as a company with thousands of workers. Full-time, part-time, and temporary employees all count. Remote workers whose jobs could be done from Colorado are covered, and out-of-state companies with Colorado staff must follow the law. Independent contractors are outside the statute, which reaches only employer-employee relationships.

Equal Pay for Substantially Similar Work

Employers cannot pay an employee of one sex less than an employee of a different sex for substantially similar work. The comparison looks at a composite of skill, effort (including shift work), and responsibility, not at job titles.² Two workers with different titles doing functionally the same job can trigger the statute. The protection also applies when sex intersects with another protected status, so a woman of color paid less than a white man for substantially similar work has the same claim as in a straightforward sex-only comparison.

When a Pay Difference Is Legal

A wage gap between employees doing substantially similar work is not automatically unlawful, but the employer carries the burden of justifying it and must satisfy all four of the following at once:²

The differential rests on a permitted factor: a seniority system, a merit system, a production system that measures quantity or quality, geographic location of the work, education or training reasonably related to the job, or travel that is a regular and necessary part of the work.
Each factor was applied reasonably.
The factors account for the entire gap, not just part of it.
Salary history was not used to justify any portion of the disparity.

The list is exhaustive. Vague references to “market conditions” or stronger negotiation by one employee do not qualify. If a $15,000 gap exists and seniority explains $10,000 of it, the remaining $5,000 is still a violation.

The salary history ban reaches further than the four-part test. Employers cannot ask applicants about prior pay or use past wages to set a new wage, and they cannot retaliate against an applicant who refuses to disclose it.²

What Job Postings Must Include

Every job posting, whether public or internal, must disclose:³

The hourly rate or salary, or the range the employer in good faith believes it might pay.
A general description of benefits and other compensation offered.
The anticipated date the application window will close.

The CDLE’s POST Rules fill in the benefit side. Employers must describe health care, retirement, paid leave (sick leave, parental leave, vacation), and any other benefits reportable for federal tax purposes. Minor perks need not be listed.⁴ A posted range can span from the lowest to the highest amount the employer genuinely believes it might pay, and final compensation may fall outside the posted range if the posted range reflected a good-faith estimate at the time.

Internal Opportunities and Career Progressions

Employers must make reasonable efforts to announce every job opportunity to all current employees on the same calendar day, before a hiring decision is made.³ The compensation and benefit disclosures required for external postings apply here too.

Within 30 calendar days after a selected candidate starts, the employer must share certain information with employees who will regularly work with that person: the candidate’s name, their former job title if they already worked for the company, their new title, and guidance on how others can express interest in similar roles going forward.

For positions with career progressions, where employees advance based on time in role or other objective criteria, the employer must separately disclose the requirements for advancement along with each position’s compensation, benefits, full- or part-time status, duties, and access to further promotion. Eligible employees must be able to see this information shortly after they begin a position in the progression.⁵

Remote Jobs and Out-of-State Employers

Remote positions that could be performed from Colorado must include the required pay transparency disclosures, even if the posting says Colorado applicants will not be considered. The CDLE has stated this plainly: a remote job performable from anywhere does not qualify for an out-of-state exception.⁵

There is a narrow carve-out. Through July 1, 2029, an employer with no physical location in Colorado and fewer than 15 remote Colorado employees only needs to notify its Colorado workers of remote job opportunities. It does not have to notify them about positions that can only be performed outside Colorado.³ Out-of-state employers with 15 or more Colorado-based workers get no exception.

Postings for jobs performed entirely outside Colorado do not need the compensation and benefit disclosures, even when visible online in Colorado. Printed notices distributed entirely outside the state are also exempt.

Discussing Wages and Retaliation

Employers cannot prohibit workers from sharing pay information as a condition of employment, and any waiver signed to that effect is unenforceable.² Workers can compare salaries, share pay stubs, and talk openly about compensation.

Retaliation against employees who invoke rights under the law is prohibited. An employer cannot fire, discipline, threaten, or interfere with someone who files a complaint, assists in an investigation, or discusses wages with coworkers. Remedies include reinstatement, lost wages, liquidated damages, and attorney fees.⁶ Because the statute preserves the right to bring other claims, additional damages under the Colorado Anti-Discrimination Act may also be available when retaliation involves intentional misconduct.

Recordkeeping

Employers must keep job descriptions and wage rate history for each employee during employment and for two years after it ends, so patterns of pay discrepancy can be detected.⁷ Payroll records should capture all forms of compensation, including bonuses, commissions, and benefits. Job descriptions should reflect actual duties, not boilerplate from when the role was first created. Records of internal postings and career progression disclosures matter too, because an employer that cannot show it posted an opportunity is poorly positioned if a worker claims they were shut out of a promotion.

Penalties and Damages

Pay Transparency Violations

Fines run from $500 to $10,000 per violation.⁸ Each missed promotion notice counts as one violation. Each job opening without required disclosures counts as one violation no matter how many postings advertised it. For a company that routinely omits salary ranges across many listings, the exposure adds up quickly.

Equal Pay Violations

An employer that violates the equal pay provisions owes the difference between what the employee was paid and what should have been paid, plus liquidated damages in the same amount. Back pay reaches up to three years.⁶ Courts can also order reinstatement, promotion, pay increases, and other equitable relief, and the employer pays the employee’s reasonable attorney fees and costs. If the employer proves good faith, the court will not award the liquidated damages, leaving only the actual economic loss.

The Pay Audit Safe Harbor

An employer that conducted a thorough and comprehensive pay audit in the two years before a lawsuit was filed can use that audit as evidence of good faith, which eliminates the liquidated damages portion of an award and roughly cuts financial exposure in half.⁶ The audit must be aimed at identifying and remedying unlawful pay disparities. Generic compensation benchmarking is unlikely to qualify, and “thorough and comprehensive” suggests coverage of the entire workforce rather than selected departments. An audit that spots disparities but prompts no corrective action will not demonstrate good faith.

How to File a Complaint or Lawsuit

An employee who believes they are being paid less because of sex has two paths. One is a complaint with the Colorado Department of Labor and Employment, which can accept and mediate complaints and investigate violations.⁹ The CDLE established a mandatory mediation process for pay transparency complaints, effective July 1, 2024.

The other is a private lawsuit in district court. The statute of limitations is two years from the violation, and the law treats each payment of a discriminatory wage as a new violation rather than counting from the original pay decision.¹⁰ That recurring-violation rule matters: the two-year clock resets with each paycheck, so employees are rarely time-barred while the disparity continues. Either party may demand a jury trial. Filing a CDLE complaint does not block a separate claim through the Colorado Civil Rights Division or other statutory or common-law claims.
