Any organization that spends $1,000,000 or more in federal award funds in a fiscal year must have a Single Audit under 2 CFR 200 Subpart F (the Uniform Guidance). These are the CPA firms that perform them, ranked by how many Single Audits each has filed with the Federal Audit Clearinghouse. Firm counts come straight from those public filings — not a paid listing or endorsement.
