Which states require sales tax registration?
Most U.S. states require you to register for sales tax once you meet that state's physical or economic nexus requirements. Economic nexus means you may need to collect sales tax in a state once your revenue or number of transactions there crosses that state's threshold, even if you have no physical presence there. Each state sets its own rules and thresholds, so requirements vary widely from state to state.
A handful of states, Alaska, Delaware, Montana, New Hampshire, and Oregon, don't impose a statewide sales tax, so registration generally isn't required there. Because the rules differ state by state, you'll typically need to register separately in every state where you meet the threshold rather than relying on a single nationwide registration.
