Single Audit Firms in Maine

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.

65 firms in Maine, most Single Audits first.

Choosing a Single Audit firm? The number of Single Audits a firm has filed is a rough proxy for experience with the Uniform Guidance, but it isn't a quality rating. Each firm page links to the specific organizations it audited and their findings, so you can look at the actual work. Always confirm licensure and independence directly with the firm.
