Colorado and Illinois Lead New Wave of Pay Transparency Mandates

The pay transparency movement continues to accelerate across the United States. Colorado, which pioneered mandatory salary range disclosures in 2021, has now expanded its law to require companies with over 50 employees to conduct annual internal equity audits and report the results to the state labor department. Illinois joined the growing list of states mandating salary range disclosures on job postings, with its law taking effect on March 1, 2026. The Illinois version is particularly robust: it requires not just salary ranges but also a general description of benefits and any performance-based compensation. Violations carry fines starting at $5,000 per posting. For job seekers, these laws are proving transformative. Research from Cornell's ILR School shows that workers in states with pay transparency laws earn 5-7% more in their first year compared to equivalent workers in states without such laws. The effect is even more pronounced for women and minorities, who historically have been disadvantaged in opaque salary negotiations. Employers are adapting in varied ways. Some have embraced radical transparency, publishing full compensation bands on company websites. Others have responded by widening salary ranges to the point of meaninglessness — a $60,000-$120,000 range technically complies but provides little useful information. HR technology vendors are capitalizing on the trend. Compensation benchmarking tools from companies like Pave, Figures, and Carta Total Comp have seen subscription growth exceeding 300% year-over-year as companies scramble to build defensible, data-driven pay structures.
