While conducting our annual audit of the U.S. Department of Housing and Urban Development’s (HUD or Department) compliance with the Payment Integrity and Information Act, HUD’s Office of the Chief Financial Officer (OCFO) informed my office that the Department will once again be unable to estimate improper payments for the Office of Public and Indian Housing’s Tenant-Based Rental Assistance (PIH-TBRA) program and the Office of Multifamily Housing Programs’ Project-Based Rental Assistance (PBRA) program for fiscal year (FY) 2023. These are the two largest program expenditures in HUD's portfolio, totaling $45.3 billion in FY 23, or 67.5 percent of HUD's total expenditures.
