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.
The short answer
Shipping orders into a state almost never means registering your LLC there. Sales tax is the obligation that usually applies. Foreign qualification usually does not, and registering where you did not need to is a recurring cost that is hard to undo.
- You only ship orders into the state Sales tax, once you cross that state’s economic threshold. Not foreign qualification. On Amazon and Etsy the marketplace facilitator laws mean the platform is usually already collecting and remitting it for you, so check what is left before you register anything.
- Your inventory sits in a warehouse there, including Amazon FBA This is the one that can trigger both. Stored inventory is physical nexus for sales tax in every state that has one, and in some states it is enough to require foreign qualification as well. Which states depends on where FBA moved your stock, which you do not choose.
- You have an employee, an office, or a warehouse you control there That is foreign qualification, not just sales tax. Most states require a registered agent with a physical address there before accepting the filing; New York makes one optional and Pennsylvania requires a registered office instead. The full trigger list.
Why this one, and when not to use it: sales tax is the obligation most online sellers actually have, and CorpNet files the state registration for it. You can register directly with each state’s revenue department yourself at no service cost, and for one or two states that is the sensible move. This is for when the threshold has been crossed in several states at once and each one has its own form. It does not register your LLC, which is a different filing with a different agency.
If you do need to foreign qualify inventory, an employee or an office in the state, not just shipping
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 three systems, explained
Sales tax vs. income tax vs. foreign qualification
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 more than $500,000 worth of products to customers in Texas (its remote-seller threshold) creates a sales tax obligation, but it does not mean you need to file your LLC as a foreign entity in Texas. For a closer look at exactly which activities trigger foreign qualification, see our triggers guide.
When ecommerce sellers do NOT need to foreign qualify
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.
Sales tax is not necessarily your only multistate obligation. A state may apply its income or franchise-tax rules even without a physical presence; the Texas Comptroller expressly recognizes economic nexus for franchise tax. For example, Amazon collecting sales tax on an order does not answer whether your LLC must register where Amazon stores your inventory, or whether you owe other state taxes. Check each state's permit and return requirements even when a marketplace collects sales tax on your behalf.
The Amazon FBA complication
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.
Tax nexus and foreign qualification use different legal tests. Inventory in a fulfillment center is a reason to review both; a tax obligation does not by itself establish that LLC registration is required. The answer depends on the state's registration rules, exemptions, and what your business does there.
Practical guidance for FBA sellers
- Sales tax: Check each inventory state's marketplace-seller rules, including whether a permit or returns are required when the marketplace collects the tax. Your own direct sales may have separate obligations.
- Foreign qualification: Review each inventory state's transacting-business test and exemptions before deciding whether to register. This guide has no measured enforcement-rate evidence; filing costs and other sellers' practices do not establish an exemption.
- Income tax: Some states (notably California and New York) have argued that FBA inventory creates income tax nexus. Talk to a tax professional about your specific situation.
When ecommerce sellers DO need to foreign qualify
The following activities warrant a state-specific registration review. Third-party inventory storage is not a nationwide exemption; neither is physical presence alone a complete test.
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, though at least one state now exempts remote workers by statute. Check the state before assuming either way. 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.
What it costs if you do need to register
Foreign qualification fees range from $50 to $750 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.

Common questions from online sellers
Do I need an LLC in every state where I have customers? Not merely because customers live there. Check whether your activities require foreign qualification under that state's law, including its interstate-commerce and order-solicitation exemptions. Separately, sales, income, or franchise-tax obligations may arise even without an office or employees 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 (under that state's own rules), 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.
If it is the sales tax half you need
Everything above is about registering the entity with a Secretary of State. Sales tax runs on a separate track with a separate agency, and crossing a state's economic nexus threshold means registering for a sales and use tax permit there before you collect anything. That registration is not something the marketplace does for you on your own website sales, and it is not part of foreign qualification. If you have crossed the threshold in states you have never filed in, the permit is the step you are missing.
Register for a sales and use tax permit
CorpNet handles the state sales and use tax registration, which is a different filing from foreign qualification and goes to a different agency. Useful when the threshold has been crossed in several states at once and each one has its own form. You can register directly with each state's revenue department yourself at no service cost; this is the option for when the number of states makes that impractical.
