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

Colorado’s 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 compensation ranges in job postings, notify current employees about internal openings, and preserve pay records. It took effect January 1, 2021, and was amended in 2024 to sharpen the rules for remote jobs and promotion notices. Transparency violations carry fines of $500 to $10,000 each, and pay discrimination triggers back pay plus an equal amount in liquidated damages.

Who Must Comply

The Act defines “employer” as the state, its political subdivisions, departments, institutions, and school districts, together with “every other person employing a person in the state.”¹ There is no minimum employee count. A one-person Colorado employer is covered on the same terms as a company with thousands of workers, and both public and private entities fall within the statute.

Coverage reaches full-time, part-time, and temporary employees. Remote workers whose jobs could be performed from Colorado are included, and out-of-state companies with Colorado-based staff must follow the requirements. Independent contractors sit outside the statute because it applies to employer-employee relationships.

Equal Pay for Substantially Similar Work

The core rule prohibits paying an employee of one sex less than an employee of a different sex for substantially similar work. Similarity is measured by a composite of skill, effort (including shift work), and responsibility, not by job title.² Two employees with different titles doing functionally the same job are comparable under the statute.

Pay differences are not automatically unlawful, but the employer bears the burden of justifying them and must prove all four of these conditions:²

The differential rests on a listed factor: a seniority system, a merit system, a production-based system measuring quantity or quality, geographic location, 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 together account for the entire pay gap.
Salary history was not used to justify any portion of the disparity.

The list is exhaustive. Vague references to market conditions or negotiation skill do not qualify. If seniority explains $10,000 of a $15,000 gap, the remaining $5,000 is still a violation.

The Salary History Ban

Employers cannot ask applicants about prior pay or rely on salary history to set wages, and they cannot retaliate against an applicant who refuses to disclose past compensation.² The ban runs through every stage of hiring.

Salary history also cannot justify a pay gap after hire. If two employees doing substantially similar work earn different amounts and the only explanation traces to what each earned at a previous job, the disparity is unlawful.³

What Job Postings Must Include

Every job posting, external or internal, must disclose:⁴

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

A posted range can run from the lowest to the highest amount the employer genuinely believes it might pay. An employer may ultimately pay outside that range if the posted range reflected a good-faith estimate at the time.⁵

Internal Postings and Promotion Notices

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. The same compensation and benefit disclosures required for external postings apply to those internal notices.⁴

After someone is selected, the employer has 30 calendar days from the new hire’s start date to share information with employees who will regularly work with that person. The notice must include the selected candidate’s name, their former title if already employed by the company, their new title, and guidance on how others can express interest in similar roles going forward.⁴

For career progressions, where employees advance automatically based on time in role or other objective criteria, employers must separately disclose the requirements for advancement along with each position’s compensation, benefits, full-time or part-time status, duties, and access to further promotion. This information must reach all eligible employees shortly after they begin a position within the progression.⁶

Remote Jobs and Out-of-State Employers

A remote position that could be performed from Colorado triggers the pay transparency requirements even if the posting says Colorado applicants will not be considered. The CDLE has been explicit: because the Act covers all jobs, a remote position performable from anywhere does not qualify for an out-of-state exception.⁶

A narrow exception runs through July 1, 2029. Employers with no physical location in Colorado and fewer than 15 employees working remotely in the state only need to provide notice of remote job opportunities to their Colorado workers. They do not need to notify Colorado employees about positions that can only be performed outside the state.⁴ Out-of-state employers with 15 or more Colorado-based workers get no exception.

Postings for jobs performed entirely outside Colorado do not need compensation and benefit disclosures, even if visible online to Colorado residents. Printed notices distributed entirely outside the state are also exempt.⁶

Recordkeeping

Employers must keep job descriptions and wage rate history for each employee throughout employment and for two years after it ends, so patterns of wage discrepancy can be detected.⁷ Payroll records should capture all forms of compensation, including bonuses, commissions, and benefits, and job descriptions should reflect actual duties rather than boilerplate from when the position was created.

Documenting the reasoning behind pay decisions matters when employees doing substantially similar work earn different amounts, because that documentation becomes the evidence if a claim is filed. Records of internal postings and career progression disclosures deserve the same treatment. An employer that cannot show it posted an internal opportunity has little to stand on if a worker claims they were shut out of a promotion.³

How Employees Enforce the Law

An employee who believes they are paid less because of sex has two paths. The first is a complaint to the Colorado Department of Labor and Employment, which accepts and mediates complaints and investigates violations.³ Effective July 1, 2024, the CDLE runs a mandatory mediation process for pay transparency complaints.

The second path is a private lawsuit in district court. The statute of limitations is two years, and the law treats each discriminatory paycheck as a new violation.⁸ That recurring-violation rule matters: the clock resets with each paycheck, so employees are rarely time-barred while a disparity continues. A CDLE complaint does not block a separate claim through the Colorado Civil Rights Division or other statutory or common-law claims.

Penalties, Damages, and the Audit Safe Harbor

An employer that violates the equal pay provisions owes economic damages equal to the pay difference, plus liquidated damages in the same amount, effectively doubling the award. Back pay can reach up to three years.⁹ Courts can also order reinstatement, promotion, pay increases, and other equitable relief, and the employer pays the worker’s reasonable attorney fees and costs.

Transparency violations, meaning failures on job postings and opportunity notices, carry fines of $500 to $10,000 per violation. Each missed promotion notice counts as one violation, and each job opening without required disclosures counts as one violation regardless of how many postings advertised that opening.¹⁰ For a company that routinely omits salary ranges across dozens of listings, the numbers climb quickly.

The statute rewards employers who look for and fix pay gaps on their own. A thorough and comprehensive pay audit conducted within the two years before a lawsuit can serve as evidence of good faith, and a court that finds good faith will not award liquidated damages.⁹ The audit must aim specifically at identifying and remedying unlawful pay disparities. A generic compensation review probably will not qualify, and an audit that finds problems but leads to no corrective action is unlikely to demonstrate good faith either.

Retaliation and the Right to Discuss Pay

Employers cannot fire, discipline, threaten, or otherwise interfere with a worker who files a complaint, assists in an investigation, or discusses wages with coworkers. They also cannot require employees to sign agreements barring them from sharing pay information, and any such agreement is unenforceable.²

A worker who experiences retaliation can file with the CDLE or sue. Remedies under the Act include reinstatement, lost wages, liquidated damages, and attorney fees.⁹ Because the statute preserves other claims, compensatory and punitive damages under the Colorado Anti-Discrimination Act may also be available when retaliation involves intentional misconduct. The right to talk about pay is what makes the rest of the law work, because employees cannot spot a disparity they are barred from discussing.
