Amazon Business (B2B on Amazon)
On the seller side, Amazon Business tax exemption means enrolling in the Amazon Tax Exemption Program in your Tax Settings so that buyers who hold a valid exemption certificate, such as schools, nonprofits, government agencies and resellers, can buy your products without sales tax being added at checkout. Amazon validates the certificate, applies the exemption, and files a copy in your Tax Document Library; you do not review certificates by hand or refund tax to exempt buyers one order at a time.
That is the Amazon version. It is convenient because Amazon does nearly all of it. The reason it matters to a brand thinking about wholesale is that the moment you sell a case to a store directly, the same exemption becomes your responsibility, and the mechanics are different enough to trip people up.
What ATEP does and where to turn it on
Go to Settings, then Tax Settings, in Seller Central. Under the tax exemption section you can enrol in the Amazon Tax Exemption Program. Enrolment is a switch, not an application. Once it is on, any order placed by a buyer whose Amazon Business account holds a validated exemption certificate for the ship-to state is processed without sales tax for the exempt items.
The buyer's side is where the paperwork happens. A purchasing manager at a school district uploads the district's exemption certificate to the organisation's Amazon Business account, chooses the states it covers and the exemption type, and Amazon validates it. From then on, anyone buying under that account gets the exemption applied automatically on orders from ATEP-enrolled sellers.
You see the result in two places. The order itself shows no tax collected, and the certificate the buyer relied on appears in your Tax Document Library under tax exemption certificates, matched to the order. That copy is your record if a state auditor ever asks why a sale went out untaxed.
Why you barely notice it as a marketplace seller
Almost every state with a sales tax now treats Amazon as the marketplace facilitator, which means Amazon calculates, collects and remits the tax on your orders rather than you. ATEP sits on top of that. For an exempt buyer, Amazon simply does not collect, and the exemption certificate is the paper trail that justifies it.
If you are not enrolled in ATEP, exempt buyers can still buy from you, but tax gets charged at checkout and the buyer has to request a tax-only refund afterwards. In facilitator states Amazon processes that refund; the buyer experience is worse, though, and organisations that buy a lot on Amazon Business learn to prefer sellers where the exemption just works. Some account admins restrict staff to ATEP-enrolled sellers for that reason. So enrolment is less about tax mechanics and more about not being filtered out by the buyers who care most about clean invoices, the same buyers described in who buys on Amazon Business.
The other reason to enrol is that a growing share of business orders come with an expectation of a proper invoice and a tax line that is either correct or correctly absent. Amazon generates those invoices for you on business orders. The invoice, the exemption, and the payment terms in Amazon Business net terms are the three things a purchasing department checks, and Amazon handles all three without you doing anything beyond turning the switches on.
The three exemption types you will see
The certificates in your Tax Document Library fall into a few kinds, and it helps to recognise them because they tell you who is buying.
A government or public entity exemption comes from a state agency, a city, a public school or a public university. These buyers are buying to use, and they are often the most reliable repeat buyers on the platform.
A nonprofit or charitable exemption comes from a hospital foundation, a church, a private school or a charity. Again, buying to use.
A resale exemption is different. This buyer is telling the state that they are buying your product to resell it and will collect tax from their own customer. A resale certificate on an Amazon Business order means someone bought your product with the intent to put it in front of their customers. On Amazon that is usually a small operation, a repair shop, a gift store owner topping up, a caterer bundling your product into a service. It is a signal, and it is the one worth paying attention to.
What changes when you sell to a store yourself
Say a gift shop that has been buying twelve units at a time on Amazon Business emails and asks for a wholesale price on a case of 24. You quote $11 on a $24 retail candle, they say yes, and you ship directly. Now the exemption is yours to manage.
You are the seller of record, not Amazon. The store is buying for resale, so in nearly every state the sale is exempt from sales tax, but only if you hold a valid resale certificate from that store before or at the time of sale. If you do not, and the state asks, you owe the tax on that sale yourself, plus whatever penalty applies. Amazon was doing this collection and record-keeping for you on every business order; now nobody is.
A resale certificate is the store's state-issued document, or the multi-state form many states accept, with their sales tax permit number, a description of what they sell, and a signature. You ask for it with the first order, keep it on file, and check it is still valid every year or so. Most brands keep a folder per retailer with the certificate, the credit application and the signed terms.
Then there is where you have to collect tax at all. Selling a case to a store in another state does not by itself create an obligation to collect there, but crossing that state's economic nexus threshold in direct sales does, and it is your direct sales that count, not your Amazon sales, which Amazon already handles. A brand that grows a real wholesale channel eventually registers in several states and files returns. That is a normal cost of the channel and it is manageable, but it is a cost, and it belongs in the comparison in Amazon Business versus wholesale rather than being discovered in year two.
A simple tax routine for a brand starting wholesale
You do not need an accountant on staff for the first few stockists. You need a routine.
- Collect a resale certificate from every retailer before the first invoice ships, and store it with the account.
- Put a tax line on every wholesale invoice, even when it is zero, with the reason it is zero.
- Track direct wholesale revenue by ship-to state in your accounting system so you can see when a state's threshold is approaching.
- Keep your Amazon Business exemption certificates in the Tax Document Library untouched; they are Amazon's records of Amazon's sales.
- Once direct sales are meaningful, get a sales tax professional to review nexus and registrations once a year.
It is a short list, and it exists because the one thing Amazon does silently for every business order, deciding whether to collect tax and keeping the paper that justifies it, is the one thing nobody does for you when you sell direct.
Using the exemption data to find real wholesale buyers
Go through the certificates in your Tax Document Library and count how many are resale exemptions. Each one is a business that bought your product to sell on. Cross-reference them with the order report's business order flag and you have a short list of small retailers who already stock you without ever having spoken to you.
Those are warm accounts. They know the product sells, they have paid Amazon's consumer-adjacent price for it, and they would take a case at a real wholesale price if someone offered. Reaching them directly is the first wholesale channel most Amazon brands open, and it costs nothing but an email. Beyond that short list, the same product usually has a whole category of stores and distributors that serve the same kind of customer. Paste the listing into WholesalePilot to see a preview of who those would be.
The tax paperwork will follow. It always does. Start it with the first case, keep the certificates, and the exemption that Amazon handled for you becomes a habit you handle yourself.
