Definition
Operating across state lines — whether by physical presence, remote employees, or economic nexus — creates filing obligations beyond your home state. Each state has its own rules, apportionment formulas, and deadlines. For independent insurance agencies in particular, multi-state complexity is the rule, not the exception.
When It Matters
When you add remote employees, sell across state lines, or operate in a regulated industry like insurance.
Common Questions
Do I have to file in every state I have a customer in?
Not necessarily, but each state has its own nexus threshold. Many states now use economic nexus thresholds (revenue or transactions in the state) in addition to physical presence.
