A Yellow Book audit (Government Auditing Standards) is required when an entity receives significant federal funding (typically over $750,000 in federal funds triggers a Single Audit, which includes Yellow Book standards), has specific federal grants or contracts mandating it, or when state/local laws or agency requests require it for public accountability, ensuring proper use of government funds. It applies to nonprofits, government bodies, and contractors handling federal money.
What Is a Yellow Book Audit? The Yellow Book, also known as the Generally Accepted Government Auditing Standards (GAGAS), delineates auditing standards established by the Comptroller General of the U.S. Government Accountability Office. It provides a framework for auditors examining recipients of government awards.
Single Audits are required for organizations that expend at least $750,000 in Federal funds in a fiscal year.
Yellow Book audits are required in several common situations:
The primary purpose of the Yellow Book is to promote fairness, uniformity, and efficiency in the valuation of real property for federal acquisitions, ensuring compliance with the constitutional requirement of just compensation under the Fifth Amendment.
Unlike a standard financial audit, a Yellow Book Audit is conducted under both Generally Accepted Governmental Auditing Standards (GAGAS) and Generally Accepted Auditing Standards (GAAS), ensuring a higher level of scrutiny, particularly for organizations receiving federal funding.
The Yellow Book contains standards for financial audits, attestation engagements, and performance audits as well as specific requirements for individual auditors and audit organizations.
If there are large amounts of fundraising income, the IRS generally expects to see related amounts of fundraising expenses. The IRS may initiate an audit if it feels fundraising expenses are not in proper proportion to fundraising income.
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.
Ten Red Flags that Could Trigger an IRS Audit
IRS audits are triggered by discrepancies the IRS's automated systems catch, like unreported income from 1099s, claiming excessive deductions (charity, business meals, home office) compared to your income bracket, large business losses, math errors, significant income jumps, or claiming hobby losses as business expenses, with higher-income earners generally facing more scrutiny.
A "Yellow Book" most commonly refers to the Government Accountability Office (GAO) website's Generally Accepted Government Auditing Standards (GAGAS), which provides guidelines for auditors of government entities and those receiving government funds, covering ethics, independence, and audit quality for financial, attestation, and performance audits. However, the term can also refer to other publications, such as the CDC's travel medicine guide or historical British literary journals.
The Yellow Book was a literary and artistic periodical, which was published between 1894 - 1897. It supposedly took its name from the illicit French novels of the fin de siècle, which often dealt openly with sexual content. These novels were wrapped in yellow paper to alert readers to their lascivious content.
Not reporting all of your income is an easy-to-avoid red flag that can lead to an audit. Taking excessive business tax deductions and mixing business and personal expenses can lead to an audit. The IRS mostly audits tax returns of those earning more than $200,000 and corporations with more than $10 million in assets.
The "33 rule" for nonprofits usually refers to the IRS Public Support Test, requiring 501(c)(3) public charities to show they receive at least one-third (33 1/3%) of their support from the general public or other public charities over a five-year rolling period, distinguishing them from private foundations by ensuring broad community reliance. This is crucial for maintaining public charity status, involves reporting on Form 990 Schedule A, and can be passed through meeting the 10% "facts and circumstances" test if the main test is missed.
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.
According to California law, a charitable nonprofit corporation with a gross annual revenue of 2 million dollars or more and that is currently required to file a report with the General Attorney must have their financial statements audited by an independent CPA.
To obtain a Yellow House Book, visit the amphoe office responsible for civil registrations in the municipality or district where your property is located. Application requirements may vary, so check with the local registration authority for specific paperwork needed.
Alongside this, the second 'asset test' threshold for charity audits is also increasing. It is proposed that charities with income over £500,000 (previously £250,000) will only require an audit if their assets are more than £5m, an increase from £3.26m.
