The Role of Supreme Audit Institutions (SAIs)
The final step in the budgetary cycle is independent external oversight. This is performed by a country’s Supreme Audit Institution (e.g., the Government Accountability Office [GAO] in the US, the European Court of Auditors [ECA] in Europe, or Auditors General worldwide). The SAI reports directly to the legislature, providing an unbiased assessment of whether the executive branch executed the budget in compliance with the law.Â
Compliance Auditing vs. Financial Statement Auditing
While a financial audit assesses whether the financial statements fairly present the economic position of the government, a Compliance Audit focuses on the legality of operations:
- The Compliance Objective: The audit verifies that every expenditure was made for the explicit purpose defined in the original legislative appropriation, remained within authorized spending ceilings, and followed public procurement regulations.
- Unlawful Expenditures: If an agency spends funds outside its legal appropriation, the auditors flag this as an un-authorized or irregular expenditure. This can lead to formal legislative sanctions, the freezing of future allotments, or criminal referrals for public officials.
Performance Auditing (Value for Money Auditing)
Modern SAIs look beyond simple compliance to conduct comprehensive performance audits. These evaluations assess whether the execution of the budget achieved real-world results efficiently and economically. Auditors analyze whether a program’s operational goals were realized at the lowest reasonable cost, determining if the taxpayers received genuine value for the public funds deployed.
