Economic nexus: the quiet exposure growing companies carry

Economic nexus does not announce itself. A company grows, a state threshold is crossed, and nobody notices until a buyer's diligence team runs a nexus study and finds several states of unregistered exposure.

Why it stays hidden

Thresholds are low and measured on a rolling basis that nobody is watching. Marketplace facilitator rules help for some channels and create confusion in others. Meanwhile the liability compounds with interest and penalties.

What to do first

Quantify before you file. A state by state exposure model tells you where registration is urgent, where voluntary disclosure makes sense, and where the amount is immaterial enough to register prospectively. Filing first and asking later can open look-back periods you did not need to open.

Then make it a monitored process

Revenue by state against threshold, reviewed monthly. Registration renewals on a calendar. Exemption certificates collected at onboarding rather than at audit. It is not complicated work. It is work that needs an owner.
