Equal Pay for Equal Work Act

Colorado’s Equal Pay for Equal Work Act (the “Act”) (C.R.S. § 8-5-101 et seq.), aims to close gender pay gaps and to ensure employees with “similar job duties are paid the same wage rate regardless of sex.” The Act has two parts. Part 1, referred to by the Division as “Unequal Pay,” requires employers to pay employees equally for substantially similar work regardless of sex. It also prohibits employers from (1) asking about an applicant’s pay history or relying on pay history to determine an employee’s wage rate; (2) discriminating or retaliating against a prospective employee for not disclosing their pay history; (3) not allowing employees to discuss pay; (4) requiring an employee to sign a document that prohibits the employee from discussing pay; (5) retaliating against an employee for using their rights under the Equal Pay Act, including by filing a complaint with this Division; and (6) retaliating against an employee for discussing pay. 

Part 2, referred to by the Division as “Pay Transparency,” requires transparency in pay and job opportunities. Specifically, it requires employers to disclose compensation in all job postings and notices, both internal and public. This disclosure must include information about benefits and how and when to apply. Employers must also disclose available job opportunities to all employees and then disclose who was selected to fill the position. In addition, if the employer uses career progressions for certain roles, it must disclose how to advance through career progressions to eligible employees. Finally, employers are required to preserve records of wages and job descriptions.


The Division investigates complaints against employers concerning unequal pay and transparency in pay and employment opportunities. If you believe that an employer violated the Act, you may file a complaint with the Division. The Division only accepts complaints in writing using the online or written forms below. You should be complete in your responses and attach any evidence you have to support your claims.

If your complaint concerns unlawful unequal pay - when an employee is paid less than another employee of a different sex for performing substantially similar work or other Part 1 violations listed above- please fill out the Unequal Pay Complaint form:

Equal Pay for Equal Work Act, Part 2 Complaint Form
