WS - C - City of Tiffin 2024 - Auditor's Report - Final

Report on Internal Control over Financial Reporting and on Compliance and Other Matters Based on an Audit of Basic Financial Statements Performed in Accordance with Government Auditing Standards Independent Auditor's Report Honorable Mayor and Members of the City Council City of Tiffin Tiffin, Iowa We have audited, in accordance with auditing standards generally accepted in the United States of America and the standards applicable to financial audits contained in Government Auditing Standards issued by the Comptroller General of the United States, (Government Auditing Standards) the basic financial statements of the governmental activities, the business-type activities, and each major fund of the City of Tiffin as of and for the year ended June 30, 2024, and the related notes to basic financial statements, which collectively comprise the City’s basic financial statements, and have issued our report thereon dated December 19, 2024. Our report expressed unmodified opinions on the governmental activities, the business type activities, and each major fund, which were prepared on the basis of cash receipts and disbursements, a basis of accounting other than U.S. general accepted accounting principles. Report on Internal Control over Financial Reporting In planning and performing our audit of the basic financial statements, we considered the City’s internal control over financial reporting (internal control) as a basis for designing audit procedures that are appropriate in the circumstances for the purpose of expressing our opinions on the basic financial statements, but not for the purpose of expressing an opinion on the effectiveness of the City’s internal control. Accordingly, we do not express an opinion on the effectiveness of the City’s internal control. A deficiency in internal control exists when the design or operation of a control does not allow management or employees, in the normal course of performing their assigned functions, to prevent, or detect and correct, misstatements on a timely basis. A material weakness is a deficiency, or a combination of deficiencies, in internal control such that there is a reasonable possibility that a material misstatement of the City’s basic financial statements will not be prevented, or detected and corrected, on a timely basis. A significant deficiency is a deficiency, or a combination of deficiencies, in internal control that is less severe than a material weakness, yet important enough to merit attention by those charged with governance. Our consideration of internal control was for the limited purpose described in the first paragraph of this section and was not designed to identify all deficiencies in internal control that might be material weaknesses or significant deficiencies and therefore, material weaknesses or significant deficiencies may exist that were not identified. We did identify certain deficiencies in internal control described in the accompanying Schedule of Findings and Responses to be material weaknesses, Audit Finding 2024-001. 43
