Where is my FBA stock, and what does it trigger?

Amazon decides which fulfillment centers hold your units, and it moves them. Amazon also collects and remits the sales tax on your marketplace orders. What Amazon does not do is tell a state you are there — and stored goods are a physical presence, which some states say makes a seller register and file, even when every sale went through Amazon. Tick the states holding your stock and see what each one's revenue department actually says, with its own page and the date we last checked it.

Selling on Amazon.in as well? The same problem in India is the fulfilment centre's state deciding your registration.

Not tax advice; confirm with the state or a tax professionalevery row links to the state's own page and shows when we last checked it. State rules change, and your own facts (an office, staff, other sales channels) can change the answer.

Step 1 — find the states from your own Seller Central reports

Amazon names these reports exactly as written here. It does not publish a public list matching a fulfillment center code to an address, so the last step is yours.

  • Inventory Ledger report— the one that says where your units are now. Amazon describes its detailed view as showing “all inventory events in fulfillment centers, including event type, quantity, location, country, and disposition”, and its summary view lets you “select Country to display inventory location by country or Fulfillment center to display inventory location by fulfillment center” (Amazon: Inventory Ledger report). Amazon also confirms it replaced the Inventory Event Detail, Daily and Monthly Inventory History, Inventory Adjustments, Received Inventory and Inventory Reconciliation reports, so older advice pointing at those is out of date (Amazon: how to find the information you need).
  • Monthly storage fees report — a second read on the same question, because storage is charged per centre. Its fulfillment-centerfield is “Fulfillment center in which the ASIN is stored”, alongside a country-code field (Amazon: Monthly storage fees report).
  • Amazon-Fulfilled Shipments Report — useful, but read it carefully. Its fulfillment-center-idis “The unique identifier from which fulfillment center the order was shipped”; the ship-statefield in the same report is the buyer's state, not the centre's (Amazon: Amazon-Fulfilled Shipments Report).
  • Your own inbound shipments— how you turn a code into a state. Each shipment you create has a ship-to destination, and Amazon says “When your shipment is split, you'll see multiple shipments created, each directed to a different fulfillment center” ( Amazon: Send to Amazon, confirm shipping). Amazon's own wording for reaching them: “Click a shipment in the Shipping Queue to go to the Shipment Summary page” ( Amazon: create shipments with Send to Amazon).

Amazon can move units between centres after they arrive, so the ledger, not your shipping history, is the list of where stock sits today. If a code appears that you never shipped to, ask Amazon where it is rather than trusting a third-party code list — none of them is Amazon's.

What the three answers mean

  • Registration required— the state's own page says a seller in this position needs a permit or licence, and usually returns with it, even though Amazon collects the tax. Those returns are often for little or no tax.
  • No registration needed — the state says in writing that a seller whose sales all go through a collecting marketplace does not have to register. Where the state adds a condition, the row says so.
  • Not confirmed— the state's pages do not settle this situation, or they point in different directions. The row links to the state so you can ask it; it never guesses on your behalf.

Amazon's side of this is its marketplace tax collection page: “As the marketplace facilitator, Amazon calculates, collects, remits, and refunds sales tax on third party sellers transactions destined to states where this legislation is enacted”. That page says nothing about your own registration — which is exactly the gap this tool fills.

How these rows were checked

Every reviewed row rests on a page published by that state's own revenue department, its statute or its administrative code — opened and read, not summarised from a vendor blog. Where a state's pages conflict, the row says “Not confirmed” and links you to the state rather than picking a side. Reviewed so far: 46 of the 46jurisdictions with a statewide sales tax, chosen to start with the ones most likely to be holding an FBA seller's units. The rest show whether the state has a sales tax, with its revenue department's link, marked “Not yet reviewed”. Sources were last checked 15 Sep 2026.

Every state at a glance

Registration required (13)

These states say a seller in this position holds a permit or licence — and usually files returns — even though the marketplace collects the tax.

No registration needed (20)

These states say in writing that a seller whose sales all go through a collecting marketplace does not have to register. Conditions, where the state sets them, are in the row.

Not confirmed (13)

Their own pages do not settle this situation, or they point in different directions. Ask the state; do not assume either answer.

No statewide sales tax (5)

Nothing to register for at state level. Local or other business taxes can still apply, so the row says what the state itself flags.

Questions Amazon US sellers ask about FBA inventory and state sales tax

Amazon already collects the sales tax. Why would a state want me to register?

Collecting the tax and being registered are two different things. Amazon says it calculates, collects, remits and refunds sales tax on third-party sellers' orders going to states with marketplace facilitator laws, so the tax on those orders is handled. Registration is about you: storing goods in a state is a physical presence there, and some states still want a seller with a physical presence to hold a permit and file returns, even when a marketplace collected every dollar of tax. Other states say the opposite in writing. This tool shows which is which.

How do I find out which states Amazon is storing my inventory in?

From your own reports. The Inventory Ledger report shows, in Amazon's words, the fulfillment center where the inventory is stored; its summary view can be aggregated by fulfillment center. The Monthly storage fees report has a fulfillment-center field described as the fulfillment center in which the ASIN is stored. Both give you fulfillment center codes such as PHX6, not states, and Amazon does not publish a list of codes and their addresses, so you match the codes to the ship-to addresses on your own inbound shipments.

Does the Amazon-Fulfilled Shipments Report answer this?

Only partly, and it is easy to misread. Its fulfillment-center-id field is where an order shipped from, which tells you Amazon had your units there, but it says nothing about units sitting in a centre that has not shipped an order yet. The ship-state field in that report is the buyer's delivery state, not the fulfillment center's state. Do not use it as your list of storage states.

What does “Registration required” mean in practice?

That the state's own page says a seller in your position needs a sales tax permit or licence. Registration usually brings filing with it: you file the returns the state assigns you, and those returns can show little or no tax due, because the marketplace already collected it. Each state's page explains how it wants marketplace sales reported, which is why every row links to the state.

What does “Not confirmed” mean?

That we could not find a clear statement from the state's own revenue department about this exact situation, or that its statements point in different directions. We do not guess in either direction. Ask the state's revenue department, using the link in the row, or a tax professional.

Is FBA inventory the only thing that can make a state want me registered?

No. This tool answers one narrow question: your only presence in the state is FBA inventory, and all of your sales there are made through Amazon, which collects the tax. Staff, an office, a 3PL, inventory you control yourself, or sales through your own website or another channel can create obligations of their own, including income or franchise taxes this tool does not cover.

How current are these answers?

Every row shows the date its official source was last opened and checked, and links straight to that source. State rules and guidance change, so treat the date as part of the answer: if it is old, open the link before acting on it.
