Commission on Audit (COA) Directory

The Commission on Audit (COA) is an independent constitutional commission  that has 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: (a) constitutional bodies, commissions and offices that have been granted fiscal autonomy under the Constitution; (b) autonomous state colleges and universities; (c) other government-owned or controlled corporations and their subsidiaries; and (d) 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.
