We audited the Pennsylvania Housing Finance Agency (Agency) because it received $95.1 million in Tax Credit Assistance Program (Program) funds under the American Recovery and Reinvestment Act of 2009 (Recovery Act). The Agency received the largest amount of Program funds awarded in Region III. Our objective was to determine whether the Agency administered its Program in accordance with Recovery Act and applicable U.S. Department of Housing and Urban Development (HUD) requirements. We found that the Agency generally administered its Program in accordance with Recovery Act and HUD requirements. However, it incurred ineligible costs totaling $135,590 and could not support costs totaling $151,936. In addition, it did not obtain required lobbying certifications from contractors and subcontractors, and it understated its job creation information that it reported to the Federal reporting Web site. We recommend that HUD require the Agency to reimburse its Program $135,590 for the ineligible costs identified by the audit and provide documentation to support $151,936 in unsupported costs identified by the audit or reimburse its Program from non-Federal funds for any costs that it cannot support. In addition, the Agency should obtain the required lobbying certifications from contractors and subcontractors and develop and implement controls to ensure that accurate job information is reported on the Federal reporting Web site.
