Payroll nexus means your business created tax obligations in a state through employee activity there, no office required. A remote hire, a relocation, or an expanding team can trigger registrations and filings you never knew existed, and most businesses find out only after the notices start arriving. Here's how to spot the exposure before that happens.

"We thought payroll was handling this" is one of the most common lines businesses say after a notice arrives, and it's usually true, payroll was running fine. The problem is that payroll processing and payroll compliance are not the same function, and registrations, work states, and filings depend on information the provider was never given. Here's why these gaps slip past even a provider that's doing its job correctly, and who actually owns closing them.

A payroll tax notice rarely starts the day it arrives. It usually traces back months, to an expansion, a remote hire, or a state registration that never got finished while payroll kept running normally. Here's why growing businesses get hit with notices after expanding, and what it actually costs to resolve one once it shows up.
