Employer registration by state

The revenue agency and the workforce agency you register with in each jurisdiction, and why one remote hire usually means two applications.

Hiring one employee in a new state generally creates two registrations, not one: an income tax withholding account with the revenue agency, and an unemployment insurance account with the workforce agency. They are separate applications, separate account numbers and separate filing calendars. In the nine states with no wage income tax you still need the unemployment registration.

This is a determination aid, not advice. StateSide encodes published state rules and applies them mechanically to the facts you enter. It does not know your entity structure, your nexus history, your equity compensation, or the dozens of exceptions that turn a clean rule into a judgement call. Every determination cites the state source it came from — verify against that source, and take anything consequential to a payroll tax professional before you act on it.
