Online business / SaaS / consulting
If you sell software, courses, or services globally with no US office, employees, or inventory, you have flexibility. Wyoming is the default: $100 to file, $60/year, no state income tax, strong privacy. New Mexico wins if you want the absolute lowest maintenance ($50 once, no annual report). Avoid California and New York unless you actually live there — their franchise taxes and publication rules erase any cross-state savings.
E-commerce and Amazon FBA
Inventory stored in an Amazon fulfillment center can create nexus in multiple states. Many sellers still form in Wyoming or their home state and deal with sales-tax nexus separately through a marketplace facilitator or a sales-tax service. If you live in Texas and run FBA from Texas, form in Texas — a Wyoming LLC does not exempt you from Texas obligations when you operate from there.
Real estate investing
Form the LLC in the state where the property sits. A Wyoming parent LLC owning a Texas rental still needs a Texas LLC (or foreign qualification) for the Texas property because the asset creates nexus. Multi-property investors sometimes use a Wyoming holding LLC that owns state-specific child LLCs — that structure is for asset protection and estate planning, not for skipping local fees.
Freelancers and local service businesses
Plumbers, designers, therapists, and contractors should form in the state where they work. The liability protection and tax simplicity come from using an LLC at all — not from picking a low-fee state three time zones away. Your home state annual report is almost always cheaper than formation state + foreign qualification combined.
Non-US founders
Wyoming for the best balance of privacy, case law, and cost. New Mexico if every dollar of maintenance matters. Delaware only if US investors are already on the cap table or term sheet. See our LLC for non-US residents guide for banking and tax specifics.
