What is a PEO?
A Professional Employer Organization (PEO) is a third-party partner that helps businesses manage employee needs—like payroll and benefits, taxes, onboarding, and legal filings.
Through a co-employment model, your business retains day-to-day control while the PEO handles administrative and compliance functions.
This partnership often leads to cost savings, more competitive retirement plans, and improved ability to scale across jurisdictions. PEOs are especially valuable when you need to include payroll, support multi-state teams, or streamline your human resource functions.
PEOs help small and mid-sized businesses streamline HR tasks, stay compliant, and cut costs. But PEO rules and benefits vary by state.
This guide links you to every local resource we’ve published—so you can make informed decisions for your business operations. We will be continually updating this list for additional coverage.
