This legislation, titled the "Delivering On Government Efficiency in Spending Act," aims to significantly enhance transparency and accountability in federal spending while combating improper payments. It mandates that federal agencies provide detailed information for each payment submitted to a Treasury disbursement system, including the purpose, appropriations account, and activity type. This information will be subject to annual verification by certifying officials and made publicly available on the Federal Funding Accountability and Transparency Act website, with exemptions for payments related to sensitive operations like national security or law enforcement where disclosure could cause harm or reveal classified information.

To further bolster program integrity and prevent erroneous disbursements, the bill grants the Secretary of the Treasury expanded access to several critical databases. This includes the National Directory of New Hires, allowing for better identification and recovery of improper payments. Agencies will also be required to verify the accuracy of bank account information for proposed recipients and compare it against other payment records before certifying vouchers, ensuring payments reach their intended destinations.

Moreover, the legislation facilitates the sharing of sensitive data, while preserving privacy, to enhance the "Do Not Pay" working system. It amends the Fair Credit Reporting Act to allow the Treasury to access consumer reports for improper payment prevention and recovery. Additionally, the Internal Revenue Code is modified to permit the Commissioner to provide specific, privacy-preserved tax return information, such as taxpayer identification numbers and adjusted gross income, to the Treasury for "Do Not Pay" system enhancements, and the Commissioner of Social Security must regularly provide personally identifiable information for the same purpose.
