Economic Nexus: A State by State Reality

There is no single national rule. Here is how to think about nexus across many states.

Quick answer

Economic nexus is not one national rule but a patchwork where each state decides how much selling into it creates an obligation. Thresholds vary in amount and basis, physical presence is not required, and a sale that matters in one state is harmless in another, so you have to assess exposure state by state.

Fifty different rulebooks

Economic nexus is not one rule but a patchwork. Each state decides for itself how much selling into it creates an obligation, which means your exposure has to be considered state by state, not as a single number. Related: Multi State Selling Without the Panic

Thresholds differ

States set their own thresholds, commonly based on sales revenue or transaction count. What crosses the line in one state may be well short of it in another, so a sale that matters in one place is harmless in another. Related: Registering in a New State, Step by Step

You can owe where you have never been

The defining feature of economic nexus is that physical presence is no longer required. Enough remote sales into a state can create an obligation there, even with no office, staff, or inventory in the state. Related: How to Know When You Are Approaching Nexus

Track each state separately

Because the rules vary, the only reliable approach is to watch your sales against each state's threshold individually. That is how you see exposure building before it becomes a missed obligation. Related: What Counts Toward a Nexus Threshold
