H.R. 4555 would amend the Help America Vote Act of 2002 to allow states to use federal funds for auditing the effectiveness and accuracy of voting systems, election technology, and procedures in federal elections. CBO estimates that enacting H.R. 4555 would not affect direct spending or revenues. CBO has not estimated the bill’s effects on spending subject to appropriation. The bill contains no intergovernmental or private-sector mandates as defined in the Unfunded Mandates Reform Act.
