Frequently asked questions

What does third-party administrative access enable Guideline to do?

With third-party administrative access, we can update employee rosters, manage contributions and pull reporting on your behalf to administer your plan.

Which payroll providers can be connected with third-party administrative access?

As of May 2024, these payroll providers include: BambooHR, iSolved. Justworks PEO, Namely, Paychex, Paycom, Paycor, and Primepay. Other payroll providers listed above have an integration with Guideline and require no third-party administrative access.

Can I decline to provide third-party administrator access to Guideline?

You can, but you would have to open up a self-service 401(k) plan. For self-service plans, Guideline will handle most 401(k) administrative tasks, including processing deductions, but you will be responsible for importing transaction and employee details into your 401(k) and maintaining deductions in payroll.
