Sales tax nexus is the connection that creates an obligation for a business to collect and file sales tax in a particular US state. It arises through physical presence (warehouse, staff, inventory) or an economic threshold (in-state sales amount or transaction count).
For sellers using FBA, the state where inventory sits can create physical nexus; because the platform moves inventory between states, nexus can arise without the seller deciding anything. Most marketplaces collect and file the tax themselves under marketplace facilitator rules, which largely removes the burden on marketplace sales. For a business selling from its own site, the obligation sits directly with the seller. Thresholds vary from state to state; collecting without registering and registering without filing both create problems.
