NSNexus by State

US States With the Most Recently Effective Nexus Laws

Updated

States that adopted or updated economic nexus thresholds most recently. Newer rules mean less settled case law and more active enforcement.

Economic nexus rules aren't static. Several states have added, removed, or updated thresholds as recently as 2024-2026. Sellers operating in newer-rule states should monitor state guidance — enforcement tends to ramp up 12-18 months after effective dates.

When a state updates its nexus rule, previously-registered sellers may find their threshold basis changed. Review your state registrations annually — deregistration is available in most states if your activity drops below the current threshold.
