Final answer:
The Federal Single Audit Act requires auditors to report on a government's internal control and compliance with laws relating to federal funds, but not on revenue estimates or appropriations certification.
Step-by-step explanation:
The Federal Single Audit Act of 1984, as amended in 1996, mandates that auditors determine and report on several aspects concerning state and local governments that receive federal funds. Among the reports normally required are a report on the government's internal control related to federal funds and a report on the government's compliance with applicable laws and regulations.
However, one requirement that is not normally part of these audits is providing a detailed estimate of anticipated revenues or certifying appropriation bills. The focus of the Single Audit Act is to assess the management of federal expenditures within state and local governments, ensuring accountability and proper usage of federal funds.
