Foreign qualification: when your Delaware LLC needs to register in another state

Triggers for foreign qualification

Physical office or workspace in the state. Employees working from the state. Warehouse or inventory in the state (FBA inventory triggers in fulfillment states). Substantial sales tied to in-state activity. State-specific licensure requirements.

Online sales alone usually do not trigger qualification (vs sales tax nexus, which has economic thresholds).

Costs and ongoing obligations

Initial filing: $50-$800 depending on state. Annual report: $20-$300/year in most states. Registered agent in each qualified state: $50-$125/year. Some states have minimum LLC tax (California $800/year, etc.).

Total annual cost of qualification in one state: typically $150-$1,000+.

Who actually needs foreign qualification

US-based founders with home-state employees: foreign-qualify in home state. Amazon FBA sellers with substantial inventory in many states: technically need qualification in those states (often not enforced unless audited). Non-resident founders with pure online ops, no US physical presence: typically no foreign qualification needed.
