Nexus: A company’s connection to a state.
Physical Nexus is created when you have physical presence in a state. This could be employees, inventory, office locations, business activity at a conference, driving a truck through the state, etc.
Economic Nexus is generally reached when a company has $100,000 in revenue and/or 200 transactions in a state in a previous or current calendar year. However, these thresholds vary by state.
