Conn. Gen. Stat. § 7-392
Making of audits and filing of statements.
(b) Notwithstanding the provisions of subsection (a) of this section, if the charter in any municipality contains provisions applicable with respect to selection of an independent auditor for purposes of such audit, such selection shall be conducted in accordance with the charter, provided such selection shall be subject to approval by the Secretary of the Office of Policy and Management.
(c) In conjunction with each audit of its financial statements, each town shall provide for the auditing of the financial statements of each school district operating within its boundaries. In the case of a regional school district, the regional board of education shall provide for such an audit.
(d) The Commissioner of Housing shall provide for the auditing of the financial statements of each local housing authority at least once biennially. Such audit may be conducted by an independent auditor or by employees of the Department of Housing, as the commissioner may determine. The commissioner may charge any housing authority for the cost of any such audit of its accounts. Upon completion of any such audit, the commissioner shall file certified copies of the audit report with the chairman and the executive director of the housing authority, with the chief executive officer and the clerk of the municipality in which such housing authority is located and with the Secretary of the Office of Policy and Management.
(e) The treasurer or other officer having authority over the financial affairs of any reporting agency shall, annually, file a statement concerning the accounts and finances of such agency with the (1) town clerk of the town in which such agency is located, and (2) Secretary of the Office of Policy and Management, upon the secretary's request. Such statement shall include, but shall not be limited to, a listing of major disbursements and sources of receipts and shall be filed not later than ninety days after the end of the fiscal year or period which is the subject of the statement. Each treasurer or other officer who fails to file a statement required pursuant to this subsection shall be fined five hundred dollars for each statement not filed. The fine shall be levied and collected by the town clerk.
Where board of finance designated firm to audit accounts but was not empowered so to do, approval by tax commissioner was invalid. 155 C. 163.
