How payroll and a 401(k) work together

Our platform will securely sync your Square Payroll and Guideline 401(k) data so any updates or changes will be reflected in both places automatically—saving you time and hassle.

Plan management
401(k) contributions are automatically deducted each pay run. No need to maintain deductions or manually re-enter payroll data.
Employee onboarding
When employees become eligible to join the plan, we’ll notify and enroll them on your behalf—and provide full support along the way.
