Outsourcing HR through a PEO is a strong option for growing businesses. Since our founding in 1989, Questco has distinguished itself with multiple key factors that help our clients more quickly reach higher levels of success: 


While many of our clients use Questco to access a comprehensive set of services, we use a flexible approach to offer you the exact blend of services you need….never forcing our clients into a “one size fits all” model.

The foundations of our offering – which every client uses – are payroll services and HR services. From there, it’s up to you. We can offer access to our group medical plans or administer your current plans. We can offer our insurance brokerage services for medical and workers’ compensation, or we can work with your existing providers and relationships toward our shared success. This flexibility helps us deliver the right mix of services for you, at every stage of your business growth cycle.

Can-do spirit

The heart of the Questco culture is an unwavering commitment to serve our clients and their people. You and your team can expect to be treated as one of ours, and we will devote a dedicated team to your success. We will know your names, and you will know ours. We form strong human bonds because of the level of care we provide, and these connections are the basis of our longstanding client relationships. We care about you, and this shows in our unmatched ability to come through for our clients and their employees every day.

A Certified Professional Employer Organization

Questco has been named a Certified Professional Employer Organization (CPEO) by the United States Internal Revenue Service. To achieve and maintain CPEO certification, Questco must continue to meet IRS requirements including tax compliance, background reports, experience, financial reporting, and bonding.

CPEO certification provides regulatory and cost certainty for current and potential clients. Specifically:

• Some wage base tax restarts are eliminated. A CPEO has successor employer status for federal payroll taxes, which means that a business that contracts with a CPEO during the year will not face double taxation on FICA and FUTA.

• Tax liability is clarified. A CPEO is solely liable for the federal employment taxes paid to worksite employees. Once the CPEO invoice that includes these taxes is paid by the client, the IRS can only collect these taxes from the CPEO.

• Tax credit eligibility is continued. A client that uses the services of a CPEO remains eligible for certain specified federal tax credits.

Our CPEO certification removes obstacles to becoming a Questco client and provides lasting peace of mind to all of our clients.
