A Single Audit is still primarily referred to as a Single Audit or a Uniform Guidance audit. It is conducted under the OMB's Uniform Administrative Requirements, Cost Principles, and Audit Requirements for Federal Awards (often called "Uniform Guidance" or 2 CFR 200 Subpart F), which replaced the old OMB Circular A-133.
A Single Audit, also known as a Uniform Guidance Audit, is a financial reporting and compliance audit focused on entities that expend $1 million or more in federal awards in a fiscal year beginning after October 1, 2024. This is an increase from the $750,000 Single Audit threshold.
In both 2025 and 2026, non-federal entities that accept $1 million or more in federal assistance must complete an annual single audit. Before 2025, the single audit threshold was $750,000. Single audit rules apply regardless of whether your organization receives federal funds directly or indirectly.
The $1 million Single Audit threshold is effective for fiscal years that begin on or after October 1, 2024. In other words, the new threshold is effective for fiscal years that end on or after September 30, 2025.
Entities that spend federal grant funds are required to submit an audit if they meet the following spending thresholds: $750,000 or more for Fiscal Years starting before October 1, 2024. $1,000,000 or more for Fiscal Years starting on or after October 1, 2024.
For financial years that begin on or after 6 April 2025
Your company may qualify for an audit exemption if it has at least 2 of the following: an annual turnover of no more than £15 million. assets worth no more than £7.5 million. 50 or fewer employees on average.
A successful internal audit function relies on four fundamental pillars, often referred to as the “4 C's”: Competence, Confidentiality, Communication, and Collaboration. These principles guide auditors in delivering meaningful and impactful results. Let's explore each of these elements in detail.
The IRS conducts audits either by mail or through an in-person interview to review your records. The interview may be at an IRS office (office audit) or at the taxpayer's home, place of business, or accountant's/representative's office (field audit).
1) Correspondence Audit
The first of the four types of tax audits are correspondence audits are the most common type of IRS audits. In fact, they comprise roughly 75% of all IRS audits.
What triggers the requirement for a Single Audit? Any non-federal entity that expends $1 million or more in federal funds during its fiscal year is required to obtain a Single Audit (or Program-specific Audit, if applicable.)
What is the 5% Rule for Materiality? Under US GAAP, the 5% rule suggests that if a misstatement is less than 5% of a financial statement item, it is generally considered not material. However this is not an absolute rule and must be applied with professional judgment.
The three main types of audits, focusing on who performs them, are Internal Audits (by employees for improvement), External Audits (by independent CPAs for stakeholders), and Government Audits/IRS Audits (by tax authorities). Alternatively, focusing on the purpose, they can be categorized as Financial Audits (financial statements), Compliance Audits (rules/regulations), and Operational Audits (efficiency/effectiveness).
Single Audits are conducted in accordance with Generally Accepted Auditing Standards, Generally Accepted Government Auditing Standards (GAGAS) issued by the Comptroller General of the United States, and the requirements of the Uniform Guidance.
The 5 Cs of audit (Criteria, Condition, Cause, Consequence, Corrective Action) are a framework for structuring clear, actionable audit findings, explaining what should be (Criteria), what is found (Condition), why it happened (Cause), what the impact is (Consequence/Effect), and how to fix it (Corrective Action/Recommendation) to drive organizational improvement and compliance.
Balancing the 3 C's in Auditing Practice
Balancing competence, confidentiality, and communication is essential for the effectiveness of the auditing process.
The Big 4 are the largest accounting and auditing firms in the world: Deloitte LLP (Deloitte), PricewaterhouseCoopers (PwC), Ernst & Young (EY) and Klynveld Peat Marwick Goerdeler (KPMG).
The four core types of financial reporting, often called the main financial statements, are the Balance Sheet, Income Statement, Cash Flow Statement, and the Statement of Shareholders' Equity, providing a complete picture of a company's financial health by showing assets/liabilities, profitability, cash movements, and changes in ownership over time, respectively.
What happens during an audit? Internal audit conducts assurance audits through a five-phase process which includes selection, planning, conducting fieldwork, reporting results, and following up on corrective action plans.
The 2-year rule for audit is quite simple. If a company meets two or more of the above criteria for two years in a row, then it must have a statutory audit. Conversely, a firm that currently has to be audited can't qualify for an audit exemption until it fails to meet at least two over the criteria over two years.
The New $1 Million Threshold – WHAT DOES THIS MEAN FOR BUSINESSES? Starting in fiscal years beginning on or after October 1, 2024, only organizations with federal expenditures of $1 million or more in a single fiscal year will be required to undergo a Single Audit.
