About Insperity

Insperity is a publicly traded (NYSE: NSP) Professional Employer Organization founded in 1986 as Administaff — a pioneer that helped create the PEO industry. Headquartered in Kingwood, Texas, Insperity rebranded in 2011. With $6.6 billion in annual revenue (2024) and an average of 312,377 worksite employees in Q4 2025 across 100,000+ client businesses, Insperity is the largest dedicated PEO in the United States. The company operates from 73 offices across 44 markets and holds IRS CPEO certification. Insperity's product suite includes three tiers: HR360, its flagship full-service PEO delivering HR technology, compliance, strategic support, payroll, benefits, and talent management; HRCore, a streamlined platform for payroll and workforce management; and HRScale, launched in early 2026 in partnership with Workday for fast-growing midsize businesses. Insperity is historically recognized as the PEO industry's legislative champion — its leadership drove Texas's PEO regulatory framework in the early 1990s and lobbied Washington for two decades until the Small Business Efficiency Act was signed into law in 2014, formally recognizing CPEOs in federal tax law.

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

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

PEO Authority Editorial Note

Insperity is the PEO for businesses that want a true strategic partner, not just an administrative vendor. Its 40-year track record, national footprint, and depth of HR advisory capabilities set it apart from newer competitors. Pricing is custom-quoted and runs at a premium. Best for: established small and mid-market businesses (25-2,000 employees) that want comprehensive HR support, in-person service, and a long-term partnership.
