The Treasury Department and IRS lack updated information on how many eligible Economic Impact Payment recipients have yet to receive their funds, the GAO said in its latest CARES Act report.
The GAO encouraged Treasury and the IRS to refine their estimate of roughly 9 million individuals to help reach those who have yet to file for an EIP.
The IRS recently said it will begin mailing letters this month encouraging eligible Americans to register on the IRS website by Oct. 15 so they can receive their payment by the end of the year.
