Commission on Audit

The Commission on Audit (COA) is the Philippines' Supreme State Audit Institution. The Philippine Constitution declares its independence as a constitutional office, grants it powers to audit all accounts pertaining to all government revenues and expenditures/uses of government resources and to prescribe accounting and auditing rules, gives it exclusive authority to define the scope and techniques for its audits, and prohibits the legislation of any law which would limit its audit coverage.

  • Mandated Functions

  • The Commission on Audit shall have the power, authority, and duty to examine, audit, and settle all accounts pertaining to the revenue and receipts of, and expenditures or uses of funds and property, owned or held in trust by, or pertaining to, the Government, or any of its subdivisions, agencies, or instrumentalities, including government-owned or controlled corporations with original charters, and on a post- audit basis:

    • constitutional bodies, commissions and offices that have been granted fiscal autonomy under this Constitution;

    • autonomous state colleges and universities;

    • other government-owned or controlled corporations and their subsidiaries; and

    • such non-governmental entities receiving subsidy or equity, directly or indirectly, from or through the Government, which are required by law or the granting institution to submit to such audit as a condition of subsidy or equity. However, where the internal control system of the audited agencies is inadequate, the Commission may adopt such measures, including temporary or special pre-audit, as are necessary and appropriate to correct the deficiencies. It shall keep the general accounts of the Government and, for such period as may be provided by law, preserve the vouchers and other supporting papers pertaining thereto.

  • The Commission shall have exclusive authority, subject to the limitations in this Article, to define the scope of its audit and examination, establish the techniques and methods required therefor, and promulgate accounting and auditing rules and regulations, including those for the prevention and disallowance of irregular, unnecessary, excessive, extravagant, or unconscionable expenditures or uses of government funds and properties.
