Risky Business: How a PEO Reduces Your Exposure
By Chris PetersonFirst published Updated
The short answer
Co-employment lets you share employer responsibility with a PEO: it takes on payroll and payroll taxes, unemployment and workers' comp claims, benefits, safety consulting, training and compliance help, while you keep the worksite, daily operations and employees' roles. It reduces your risk but doesn't remove it.
Being in business is risky. You have to stay competitive with research, marketing and production, and you have to take care of the people who make it all possible: your employees.
One injury or lawsuit can put a business under. Managing people is one of the most complex, risky jobs an owner has, with rising health and workers' comp costs, more government compliance and the fight to keep good employees. That stress can keep you up at night and pull you away from running the business. For your employees' sake and your own, it makes sense to have a professional making sure you follow labor and tax laws.
How does a PEO share the risk?
Co-employment with a professional employer organization (PEO) gives you time to focus on the business instead of employment rules and paperwork. You share legal responsibility for your employees with the PEO, which becomes the employer of record for tax and insurance purposes while you keep control of operations and your worksite employees.
What is the PEO responsible for?
- Payroll and payroll taxes
- Unemployment insurance and claims
- Workers' compensation
- Employee benefits
- Safety consulting
- Employee and supervisor training
- Legal and regulatory compliance help
What stays with your business?
- Worksite conditions
- Day-to-day operations
- Deciding employees' roles
Sharing liability and responsibility with a PEO lowers your risk as an owner, and co-employment can also lower payroll and administrative costs while freeing your time for strategy.
As Aaron Pratt, SVP of Employee Benefits at Frost Insurance, put it: “You can't outsource to an HR service and actually have the liability shift to an HR generalist; you still own the liability. When you're co-employed, you're bringing in a professional employer to actually participate in the risk with you, and to me that's probably where the game is won.”
What are the limits?
A PEO shares risk; it doesn't take it all. Your business is still responsible for compliance and for the worksite. One limit worth knowing: unless your PEO is IRS-certified (a CPEO), your business generally stays responsible for its federal employment taxes, whatever the contract says (IRS, 2026). A CPEO is solely liable for federal employment taxes on the wages it pays.
