CBO Show Your Work Act

This bill requires the Congressional Budget Office (CBO) to publicly publish the models, data, and detailed methodology it uses to estimate the costs and effects of legislation. Specifically, it mandates that the CBO make available all fiscal models, data routines, and the underlying assumptions behind its cost estimates, allowing independent verification. This applies to all CBO analyses of proposed bills, including the specific data and computational details needed for others to replicate the results. The requirement applies to all users of CBO reports - lawmakers, researchers, and the public - except for data legally restricted from disclosure, which would still require a public list of variables and descriptive statistics.
