What a Yellow Book audit is

A Yellow Book audit is an audit performed under Government Auditing Standards, known as GAGAS or the Yellow Book, issued by the U.S. Government Accountability Office. It is a layer of standards on top of the ordinary audit standards, so it applies to governments, nonprofits, universities, and businesses that receive or spend federal funds.

The Yellow Book adds independence, documentation, and reporting requirements beyond a standard audit. In practice, that means you receive an extra report alongside the opinion on your financial statements.

This is audit and attest work, not tax preparation.

Two-report structure

What makes an audit a Yellow Book audit

The Yellow Book is a layer of standards on top of the generally accepted auditing standards (GAAS). When your audit follows both, you receive two reports.

The opinion on your financial statements

The standard GAAS report on whether your statements are fairly presented.

The Yellow Book report on internal control and compliance

A separate report on internal control over financial reporting and on your compliance with laws, regulations, and agreement terms. This second report is what makes it a Yellow Book audit.

Engagement types

The three types of Yellow Book engagement

The Yellow Book covers three kinds of engagement. Dimov Audit focuses on the financial side, which is the financial audit and attestation work.

  1. Financial audits

    An opinion on whether the financial statements are fairly presented.
  2. Attestation engagements

    Examinations, reviews, or agreed upon procedures on a specific subject matter or assertion.
  3. Performance audits

    An assessment of whether a program is economical, efficient, and effective.

When required

When a Yellow Book audit is required

You need a Yellow Book audit when a law, an agreement, or a funder requires your audit to follow Government Auditing Standards.

  • A grant agreement requires GAGAS, which can apply even below the single audit threshold.

  • A debt or loan agreement requires it, for example electric membership corporations with Rural Utilities Service loans.

  • State or local law requires it for your type of entity.

  • You elect it in the engagement letter, even when no rule requires it.

Single audit, in short. A single audit is performed under the Yellow Book, so it is one of the most common reasons an organization needs one. For the $1,000,000 threshold, the SEFA, and major program details, see our single audit page.

Auditor qualifications

How to tell your Yellow Book auditor is qualified

Not every CPA firm can perform a Yellow Book audit. A qualified firm meets specific requirements.

    At least 80 hours every two years, with 24 directly in government auditing.
  • Independence under GAGAS

    Stricter independence rules than a standard audit, especially around nonaudit services.
  • External peer review

    An independent review every three years that covers the firm's GAGAS engagements.
  • Current standards

    Up to date on the 2024 Yellow Book revision.

How to prepare

How to prepare for a Yellow Book audit

Preparation keeps a Yellow Book audit on schedule. Before we start, get these in order.

  • Reconcile your records and grant schedules.
  • Document your controls over federal funds.
  • Resolve prior year findings and complete corrective action.
  • Gather your grant and debt agreements so we can confirm what applies.

Not sure you are ready?

Start with a readiness review

Many organizations are not fully audit ready on day one. We assess where your records stand and give you a clear plan. Your team makes the changes and we handle the audit when you are set. We assess and advise, we do not prepare or adjust your records, which is how we protect our independence to audit you.

What a Yellow Book audit costs

Cost depends on scope, not a flat rate.

These are the factors, not a quote. We price against your funding and reporting once we understand the engagement.
