Dear Speaker Johnson and Majority Leader Scalise:
The undersigned state, regional, local, and metro chambers of commerce strongly support H.R. 1163, the Prove It Act of 2025, and urge the House of Representatives to consider and pass this important legislation to strengthen the Regulatory Flexibility Act (RFA) and bolster the voice of small business in our nation’s capital.
The RFA was passed 46 years ago and was intended to correct the lopsided burden on small business and require that regulators tailor rules to meet government objectives while minimizing the burden on small businesses. Unfortunately, federal agencies too often exploit loopholes in the law to hide costs imposed on Main Street businesses and to ignore their feedback.
H.R. 1163, the Prove It Act of 2025, would close those loopholes and bring more transparency to the true costs of red tape on America’s innovators, job creators, and community builders. Specifically, the legislation would:
• Improve transparency in the regulatory process by requiring agencies to fully disclose and justify their analyses of small business impacts;
• Enhance opportunities for small businesses to provide input early in the rulemaking process, so that agencies can design rules with greater flexibility and clearer compliance pathways; and
• Reinforce the core purpose of the RFA, ensuring that federal agencies “prove” their assumptions and methodologies when they claim a rule will not significantly affect small businesses.
On behalf of the chambers of commerce listed below, and the small businesses they represent, we respectfully urge the House of Representatives to move expeditiously to consider and pass H.R. 1163, the Prove It Act of 2025.
Sincerely,
U.S. Chamber of Commerce
