If you sell products online through Amazon, Etsy, Shopify, or your own website, you have probably heard that selling into other states creates obligations. That is true, but the obligations are not all the same. Sales tax, income tax, and LLC registration (foreign qualification) are three separate systems with different rules, different triggers, and different consequences.
Most ecommerce sellers confuse these and either over-comply (registering their LLC in states where they do not need to) or under-comply (ignoring registration in states where they should). This guide separates the three.
The critical distinction: you can have sales tax obligations in a state without needing to register your LLC there. Sales tax nexus has a much lower bar than foreign qualification. Selling $100,000 worth of products to customers in Texas creates a sales tax obligation, but it does not mean you need to file your LLC as a foreign entity in Texas.
If your business looks like this, you probably do not need to register your LLC in other states:
You sell online from your home state. You have no employees, office, or warehouse in any other state. Your products ship from your home or from a third-party fulfillment service (like Amazon FBA — but read the next section). You do not own or lease property in other states.
In this scenario, your only multi-state obligation is sales tax, and if you sell through Amazon, Etsy, or eBay, the marketplace handles sales tax collection in all states with facilitator laws (currently 46 states plus DC). You may still need to register for sales tax permits and file returns in states where you have nexus, even if the marketplace collects on your behalf.
This is where it gets genuinely complicated. If you use Amazon FBA (Fulfillment by Amazon), Amazon stores your inventory in fulfillment centers across the country. You do not choose which states. Amazon decides based on demand patterns and warehouse capacity.
Having inventory stored in a state creates physical nexus in that state. Physical nexus can trigger both sales tax obligations and, potentially, foreign qualification requirements. The question is whether inventory stored by a third party in a warehouse you do not control counts as “doing business” for LLC registration purposes.
The honest answer: this is a gray area. States have been aggressive about claiming sales tax nexus from FBA inventory. They have been less aggressive about requiring LLC registration for the same reason. But the legal theory is the same, and a state that wanted to enforce could argue that your inventory in their warehouse constitutes doing business.
You cross the line from “online sales” into “doing business” when your physical presence in another state goes beyond passive inventory storage. Common triggers for ecommerce businesses:
You hire W-2 employees in another state. This is the clearest trigger. Even one remote employee in another state can require foreign qualification there. Independent contractors (1099) generally do not trigger it, though some states are blurring this line.
You lease warehouse or office space. If you rent your own warehouse, co-packing facility, or office in another state (as opposed to using a third-party fulfillment service), that creates a direct physical presence.
You regularly attend trade shows or pop-up markets. A one-time trade show is usually exempt. But if you have a regular physical sales presence in another state — monthly farmers markets, recurring craft fairs, a seasonal retail location — that looks more like doing business.
You store inventory in your own facility in another state. Unlike FBA where Amazon controls the location, leasing your own storage space is an unambiguous physical presence.
Foreign qualification fees range from $50 to $900 depending on the state. Annual obligations include report fees, franchise taxes (in some states), and a registered agent in each state where you register. For an ecommerce business expanding into 2 to 3 states with employees or facilities, expect $500 to $2,000 in first-year costs and $300 to $1,500/year ongoing.
Our state filing guides list the exact fees, forms, and annual requirements for every state. The compliance check tool can tell you which states need registration based on where your LLC has presence.
Do I need an LLC in every state where I have customers? No. Having customers in a state does not require LLC registration. It may create sales tax nexus, but that is a separate system. You only need to register your LLC in states where you are “doing business,” which requires a physical presence beyond just selling to people there.
Does Shopify or my own website change anything? If you sell through your own website and you have sales tax nexus in a state (typically $100,000+ in sales), you are responsible for collecting and remitting sales tax yourself. Marketplace facilitator laws only apply to sales made through the marketplace. This is a sales tax question, not a foreign qualification question.
I sell digital products. Does any of this apply? Digital products have their own sales tax rules that vary by state. But from a foreign qualification standpoint, selling digital products to customers in other states almost never triggers registration requirements. There is no inventory, no physical presence, and no employees in the customer’s state.
My LLC is in one state but I moved to another. What now? If you moved your home and your business operations moved with you, your new state will likely consider you to be doing business there. You need to either foreign qualify in the new state or domesticate (transfer) your LLC to the new state. Our foreign qualification guide covers both options.
