American One Source holds CPEO status — a distinction held by fewer than 15% of PEOs in the United States.

Federal Tax Liability
As a CPEO, American One Source assumes sole liability for federal employment taxes on wages paid — protecting your business from tax exposure.
Annual Financial Audits
CPEOs undergo independent CPA audits annually and must maintain a surety bond, ensuring fiscal accountability and solvency.

American One Source files employment taxes under their own EIN as CPEO, simplifying your year-end tax obligations and eliminating duplicate filings.
