An LLC for Amazon FBA sellers
An Amazon FBA or e-commerce business sells physical products to strangers across the country, often with inventory sitting in warehouses the seller never visits. That combination — product in many hands, customers in many states — is exactly the kind of activity an LLC is built to wrap. Forming a limited liability company does not change how a store sells; it changes who is on the hook when something goes wrong and how the money is tracked. None of what follows is legal or tax advice, and the specifics vary by state in 2026, so a professional should confirm anything material to a particular store.
The core reason sellers form an LLC is the liability shield. A product can be defective, mislabeled, or cause an injury, and a buyer can claim damages. Operating as a sole proprietor leaves the owner’s personal assets — house, savings, car — exposed to those claims. An LLC, run properly, generally limits exposure to what the business itself owns. For a store carrying inventory and shipping at volume, that separation is the whole point.
Why FBA and e-commerce sellers form an LLC
Beyond raw liability, an LLC gives a store structure that mirrors how a real business operates. A few drivers come up again and again:
- Product liability separation. Selling goods made by someone else does not make the seller immune from claims; an LLC keeps those claims pointed at the business rather than the founder.
- Clean separation of money. A dedicated entity makes it natural to keep store revenue, supplier payments, and Amazon disbursements out of a personal checking account.
- Professional credibility. Suppliers, freight forwarders, and wholesale accounts often prefer to deal with a registered business with an EIN rather than an individual.
- Brand registry and growth. Sellers building a private-label brand frequently want a registered business behind the trademark and the Amazon Brand Registry application.
An LLC is a popular choice over a corporation for most solo and small sellers because it offers the liability shield with far less ongoing formality and a default pass-through tax treatment — profits flow to the owner’s personal return rather than being taxed at an entity level.
Sales tax and the nexus problem FBA creates
The single most misunderstood issue for FBA sellers is sales-tax nexus. Nexus is the connection between a seller and a state that obligates the seller to deal with that state’s sales tax. Two kinds matter here. Physical nexus is created by having property in a state — and inventory counts. Because Amazon moves FBA stock between fulfillment centers across many states, a seller can end up with inventory physically sitting in states they have never set foot in. Economic nexus is created by crossing a sales threshold in a state, commonly measured in dollars of sales or number of transactions over a year, even with no physical presence at all.
The picture changed substantially with marketplace-facilitator laws. In essentially every state with a sales tax, the marketplace itself — Amazon — is now responsible for calculating, collecting, and remitting sales tax on transactions that run through its platform. That shifts the heavy lifting off the individual seller for marketplace sales. It does not always erase the seller’s own obligations, though. A seller may still need to register in states where they have nexus, may have to file returns even when the marketplace collects, and is fully responsible for tax on sales made through their own website or other channels. The rules and thresholds differ from state to state and change over time, so this is an area where a sales-tax specialist earns the fee.
| Concept | What it means for an FBA seller |
|---|---|
| Physical nexus | Inventory stored in a state’s fulfillment center can create it, even with no other presence |
| Economic nexus | Crossing a state’s sales or transaction threshold creates it without any physical presence |
| Marketplace facilitator | Amazon collects and remits tax on marketplace sales in states that have these laws |
| Registration | May still be required where nexus exists, even when the marketplace collects |
| Own-website sales | Generally the seller’s own responsibility to collect and remit where nexus exists |
Where to form the LLC
Sellers often hear that they should form in a no-income-tax state to save money. For most e-commerce operators, that advice backfires. An LLC is usually best formed in the state where the owner lives and works, because forming elsewhere typically means also registering as a foreign LLC in the home state — paying two sets of fees and maintaining two registered agents — without escaping home-state tax. Inventory sitting in another state’s warehouse does not, by itself, require forming the LLC there; it is a sales-tax question, not a formation question. The home state is the simple, common answer unless a specific reason says otherwise.
The practical setup checklist
Once the LLC is filed with the state, a handful of steps turn it into a working e-commerce business:
- Get an EIN. The federal Employer Identification Number is the business’s tax ID; it is needed to open a bank account, register for sales-tax permits, and identify the business to Amazon.
- Open a business bank account. Routing all Amazon disbursements and supplier payments through a dedicated account is what keeps the liability shield intact and the bookkeeping clean.
- Register for sales-tax permits. In states where the seller has nexus and an obligation, a permit (sometimes called a seller’s permit or reseller permit) may be required before collecting.
- Get a resale certificate. This lets the business buy inventory for resale without paying sales tax on the purchase, since tax is collected when the item is sold.
- Update the Amazon account. Selling under the LLC means giving Amazon the business name, EIN, and bank details so disbursements and tax documents match the entity.
Non-US sellers
A large share of FBA sellers operate from outside the United States, and an LLC is a common vehicle for them too. A non-US founder generally can form a US LLC and obtain an EIN without a Social Security number — the IRS provides a path for responsible parties who lack an SSN. The tax picture is different and more involved for foreign owners. A single-member LLC owned by a non-US person is typically a disregarded entity that carries its own federal reporting obligations, including Form 5472, which reports transactions between the LLC and its foreign owner. The penalties for missing that filing are steep, so foreign sellers should treat it as a non-negotiable part of running a US LLC. Banking and payment-processor verification can also be more involved without a US presence.
How a seller’s LLC is taxed
A single-owner e-commerce LLC is, by default, a disregarded entity. The business’s profit and loss flow onto the owner’s personal return, typically on Schedule C, and the net profit is subject to income tax and self-employment tax — the combined Social Security and Medicare tax that an employee normally splits with an employer. There is no separate business-level federal income tax in the default case, which keeps things simple for a new store. As a store scales and consistent profit appears, some sellers model an S-corporation election to reduce self-employment tax, paying a reasonable salary and taking the remainder as a distribution; that move adds payroll and filing costs and only pays off above a certain profit level, so it is worth running the numbers with an accountant rather than electing reflexively. Sales tax, income tax, and self-employment tax are three separate systems, and conflating them is a common source of confusion for sellers.
Inventory accounting and recordkeeping
Beyond entity choice, product sellers carry a bookkeeping burden that pure service businesses do not: inventory. The cost of goods a store buys is generally not deducted when purchased but when sold, which means a seller has to track what was bought, what remains on hand, and what was sold to arrive at an accurate cost of goods sold. Running every supplier payment, freight charge, Amazon fee, and disbursement through the LLC’s dedicated bank account is what makes that tracking possible without reconstructing the year from memory. Amazon’s own fee structure — referral fees, FBA fulfillment and storage fees, advertising spend — should all flow through the business account so the books reflect the true margin on each product. Clean books are also what keep the liability shield defensible, since mixing personal and business money is the habit most likely to undermine an LLC’s protection.
Putting it together
For most product sellers, the LLC is the foundation and everything else — EIN, bank account, permits, resale certificate — stacks on top of it. The structure protects personal assets from product claims and gives the business a clean financial spine. The sales-tax layer is the part that catches sellers off guard, because FBA can spread a tiny operation’s inventory across the map; the saving grace is that marketplace-facilitator laws now put most of that collection burden on Amazon. The right move is to form the LLC in the home state, complete the setup checklist, keep disciplined books that account for inventory, and bring in a sales-tax professional once sales scale or cross state lines in a way that creates real exposure.
Frequently asked questions
Do I need an LLC to sell on Amazon FBA?
No. Amazon allows individuals to sell as sole proprietors. Sellers form an LLC by choice — to shield personal assets from product-related claims, separate business money, and present a registered business to suppliers and Amazon Brand Registry. It is a risk and structure decision, not an Amazon requirement.
Does storing FBA inventory in a state create sales-tax nexus?
It can. Inventory physically located in a state's fulfillment center is a form of physical presence that can create nexus. However, marketplace-facilitator laws now make Amazon responsible for collecting and remitting tax on marketplace sales in nearly every sales-tax state, which shifts most of that burden off the individual seller.
If Amazon collects sales tax, do I still need to register?
Possibly. Marketplace-facilitator laws put collection on Amazon for marketplace sales, but a seller may still be required to register in states where they have nexus, may need to file returns, and is generally responsible for tax on sales made through their own website. The rules vary by state.
What state should an FBA seller form the LLC in?
For most sellers, the home state where the owner lives and works. Forming in a different state usually forces a foreign-LLC registration back home — double fees and agents — without escaping home-state tax. Inventory in another state's warehouse is a sales-tax matter, not a reason to form the LLC there.
Can a non-US resident form a US LLC for Amazon?
Yes. A non-US founder can generally form a US LLC and obtain an EIN without a Social Security number. The federal tax and reporting obligations differ, though — a foreign-owned single-member LLC typically must file Form 5472, which carries significant penalties if missed.
What is a resale certificate and why does a seller need one?
A resale certificate lets a business buy inventory intended for resale without paying sales tax on that purchase, because tax is instead collected from the end customer at the time of sale. Sellers register for the relevant sales-tax permit and use the certificate with suppliers.
