- Potential benefitFacilitates academic and non-governmental research using CBO models and assumptions.
CBO Show Your Work Act
Referred to the House Committee on the Budget.
This bill amends Section 402 of the Congressional Budget Act to require the Director of the Congressional Budget Office to publish on the CBO website the fiscal and policy models, data preparation routines, estimates, assumptions, programs, and other computation details used for cost and effect estimates. Updates to models must be published; when data cannot be disclosed, CBO must publish variable lists, descriptive statistics, the statutory basis for nondisclosure, and contact information for those with unrestricted access.
Liberals focus on privacy protections; conservatives focus on exposure of assumptions.
Relative to its intended legislative type, this bill clearly articulates a specific operational change (publication of CBO models, data, and computational details), identifies the implementing official, and provides a short effective-date timeline, while addressing nondisclosable-data situations.

The requirement takes effect six months after enactment.
Content is narrow and non‑spending, improving chance, but unresolved legal, privacy, and contractual issues lower near‑term prospects absent amendments.
Relative to its intended legislative type, this bill clearly articulates a specific operational change (publication of CBO models, data, and computational details), identifies the implementing official, and provides a short effective-date timeline, while addressing nondisclosable-data situations. It leaves several practical implementation elements unspecified, notably funding, technical standards for reproducibility, detailed timelines for disclosure, handling of proprietary or classified materials beyond statutory references, and enforcement or oversight mechanisms.
Liberals focus on privacy protections; conservatives focus on exposure of assumptions.
Who stands to gain, and who may push back.
These are examples from the analysis, not a ranked list of the most-affected groups.
- Potential burdenPreparing publishable, reproducible models and code will likely increase CBO workload and costs.
- Potential burdenLegal or contractual conflicts could limit use of proprietary third-party data for CBO estimates.
- Potential burdenRisk of inadvertently disclosing sensitive or personally identifiable information despite exceptions.
Why the argument around this bill splits.
Liberals focus on privacy protections; conservatives focus on exposure of assumptions.
Generally supportive of greater transparency in government analysis, seeing improved accountability and reproducibility.
Concerned about protecting personally identifiable information and legal or statutory limits on data disclosure.
Favors transparency and reproducibility but emphasizes practical constraints.
Wants careful implementation to avoid legal violations, cost overruns, or impaired CBO functioning.
Broadly supportive as a government accountability reform that forces CBO to show assumptions and models.
Views public scrutiny as a check on perceived bias in scoring.
