FAQ

Frequently asked questions.

What is sales tax nexus?
The connection between your business and a state strong enough to require sales tax collection. Economic nexus (cross a revenue/transaction threshold), physical nexus (inventory, office, employees), or marketplace nexus (sold via Amazon, Etsy, eBay).
Does marketplace facilitator help?
In many states yes. Amazon, Etsy, eBay now collect sales tax on your behalf in most states. You may still need to register but the collection burden lifts. We map this state by state.
FBA inventory and nexus?
FBA inventory in a state creates physical nexus there. This means you may owe sales tax even before crossing the economic threshold.
Where should I form my LLC?
Most ecommerce founders form in their home state. Some form in Wyoming or Delaware for privacy and tax structure, then foreign-qualify where they operate.
Amazon Brand Registry?
Requires a federal trademark. We file the trademark and walk you through Brand Registry enrollment.
What about international sales?
You may owe VAT/GST in countries you sell to. We do not currently handle international tax registration, but we connect to partners who do.
Multi-entity for multi-brand sellers?
Common. Each brand in its own LLC under a holding LLC. We form and manage each entity.
Stripe Atlas vs File.Business?
Stripe Atlas is great for Delaware C-Corp formation. We handle LLCs, S-Corps, multi-state nexus, and ongoing compliance that Atlas does not.
How fast can I be live?
Formation + EIN: 1 to 3 days. Sales tax nexus assessment: 1 day. Multi-state permit filing: 5 to 30 days depending on states.
