Colorado's Equal Pay for Equal Work Act has been in effect since January 1, 2021. If you employ people in Colorado and you're still treating pay transparency as a future problem, it isn't. It's a present one.

I work with employers who get caught off guard by this law. Not because they intend to discriminate, but because their pay practices weren't built to be examined. The law assumes your compensation structure can hold up to scrutiny. Most can't — yet.

What the law actually requires

The Equal Pay for Equal Work Act (EPEWA) prohibits employers from paying less for substantially similar work based on sex, including gender identity, alone or in combination with another protected status. "Substantially similar" is measured by skill, effort, and responsibility — not job title.

Beyond the non-discrimination core, the Act imposes concrete obligations. Employers must list compensation in job postings. They must notify employees of promotional opportunities. They must let employees discuss their own pay. And they must keep job description and wage rate records.

The CDLE spells out more detail in its Posting, Screening, and Transparency Rules: job postings must include compensation, benefits, and the application deadline. Employers must notify employees of job opportunities and of hiring decisions. The records requirement stands alongside all of it.

Colorado employers with employees in the state must comply — including for remote jobs. An out-of-state employer with no existing Colorado staff that posts a remote job is not covered by the posting requirement, even if a Coloradan applies. That's a narrow exception, and most employers I see don't qualify for it.

Where employers get caught out

The job posting requirement is the most visible failure point. Every Colorado-facing posting needs a compensation range or rate. Not "competitive." Not "DOE." A number.

The less obvious traps catch employers who comply on postings but fall apart underneath. Internal promotions announced only to a favored few. Pay ranges that exist on paper but don't match what's actually paid. Job descriptions that haven't been touched since the role was created, so "substantially similar" becomes impossible to evaluate.

This is where the law exposes weaknesses you already had. It doesn't create them. If your ranges were never defensible, transparency just makes that visible faster.

A readiness path that holds up

I use a five-area readiness framework with my clients. Colorado employers can map their EPEWA obligations directly onto it.

Start with pay equity — look for unexplained gaps across protected categories before the law, or a complaint, asks you to. Then build salary range structure: defined, defensible ranges for every role, not ranges you reverse-engineer the week a posting goes live. Legal checkpoints is where you map EPEWA's specific requirements to your actual processes and close every gap. Manager readiness matters because your managers — not your policy documents — are who employees talk to when a pay question gets real. And communication planning, deciding how and when you'll share pay information, keeps disclosure from becoming a scramble.

None of this is optional anymore. It's the operating system the law expects you to already have running.

What this is, and isn't

This is a practitioner's read on what EPEWA asks of you in practice. It isn't legal advice. The Colorado Department of Labor and Employment enforces the Act and has emphasized education over penalties in its early years — but the obligations are real, and the expectations are rising. If you want a defensible pay program, build it before someone asks to see it.

If you're not sure where you stand, my Pay Transparency Readiness Checklist walks through all five areas. Start there.
