H.R. 724 – CBO Show Your Work Act

AI-Generated Summary

Updated November 24, 2025 at 3:19 AM UTC

The CBO Show Your Work Act would require the Congressional Budget Office to post online the fiscal and mathematical models, data sets, and detailed calculations it uses to estimate the costs and other effects of legislation. The goal is to let members of Congress and the public see and, if possible, replicate those estimates. The rule would take effect six months after the law is passed.

Key Provisions

The CBO must make publicly available on its website every fiscal model, policy model, and data‑preparation routine it uses for cost estimates.
Updates to any model or routine must also be posted.
For each cost estimate, the CBO must release the data, programs, models, assumptions, and computation details sufficient for an outside party to replicate the estimate.
If certain data cannot be disclosed, the CBO must still provide a full list of variables, descriptive statistics, the legal reason for nondisclosure, and contact information for the entity that can access the data.
These requirements become effective six months after the act is enacted.
