The legal connection between an employer and a state that creates an obligation to register for, withhold, and remit state payroll taxes. Nexus is typically established when an employee works or lives in a state.
Why Payroll Tax Nexus matters for employers
Common nexus-creating activities include having full-time remote employees, assigning employees to work at a client site, sending sales representatives into a state on a regular basis, and opening a new office or facility. Some states have enacted economic nexus standards that create payroll obligations based on revenue or transaction thresholds, not just physical presence.
Failing to register and withhold in a state where nexus exists creates back-tax liability for all periods in which employees worked there, plus interest and penalties. States actively share information through the Multistate Tax Commission and federal new hire reporting databases, making unregistered payroll activity increasingly detectable. BEG identifies nexus obligations during onboarding and manages registration in all applicable states.
