IRS Certification

IRS Certified PEO (CPEO)
Certification active · Verified by PEO Authority
Certified ✓

The IRS Certified PEO (CPEO) designation is awarded by the Internal Revenue Service to PEO companies that meet rigorous standards for financial health, tax compliance, and operational integrity. Group Management Services holds CPEO status — a distinction held by fewer than 15% of PEOs in the United States.

Federal Tax Liability
As a CPEO, Group Management Services 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.
IRS Reporting
Group Management Services files employment taxes under their own EIN as CPEO, simplifying your year-end tax obligations and eliminating duplicate filings.
