Cost Estimates Improvement Act

HR 991, the Cost Estimates Improvement Act, requires the Congressional Budget Office (CBO) and Joint Committee on Taxation (JCT) to include debt servicing costs (interest payments on the national debt) in their budget estimates "to the extent practicable." This change directly affects how Congress evaluates the fiscal impact of proposed legislation, as these estimates determine whether bills qualify for budget reconciliation and influence funding decisions. The key mechanism amends the 1974 Congressional Budget Act to mandate this inclusion within existing cost estimation processes. The bill does not alter spending or tax policy but aims to make budget scoring more comprehensive by accounting for ongoing interest costs.
