Amazon FBA Physical Nexus: Why You Still Have Sales Tax Obligations in States Where Amazon Already Remits
Amazon collects and remits sales tax on every order placed through Amazon.com. That is marketplace facilitator law working as intended. But if you use Fulfillment by Amazon (FBA), your inventory is physically stored in Amazon warehouses across multiple states — and that creates physical nexus in each of those states. Physical nexus is a completely separate trigger from marketplace facilitator coverage. It means you have sales tax obligations on all non-marketplace sales in those states: your Shopify store, your own website, wholesale orders, and any other channel where a marketplace facilitator is not remitting on your behalf. Sellers who assume “Amazon handles my tax” often discover years of unfiled physical-nexus returns when they finally consult a tax professional.
Key Takeaways
- • FBA inventory in a state = physical nexus in that state — regardless of your sales volume, regardless of marketplace facilitator coverage on Amazon orders
- • Marketplace facilitator laws only cover marketplace sales — Amazon remits tax on Amazon.com orders, but your Shopify, direct, or wholesale sales in the same state are your responsibility
- • Amazon can move your inventory without notifying you — distributed placement means your nexus footprint expands automatically as Amazon optimizes its network
- • $0 in direct sales does not eliminate the registration obligation — physical nexus creates a duty to register even if all current sales flow through a marketplace facilitator
- • Voluntary disclosure agreements (VDAs) limit lookback periods and waive penalties — use one before registering if you have multiple years of unfiled physical-nexus returns
- • The FBA Inventory Ledger report is your nexus audit trail — it shows which fulfillment centers held your inventory and when, translating directly to state-by-state exposure
Two Independent Nexus Triggers for FBA Sellers
Every FBA seller has two completely independent paths to sales tax nexus in a given state. Understanding the distinction is critical because most sellers only think about one of them.
| Nexus Type | Trigger | Covered by Amazon's Facilitator Status? | Your Obligation |
|---|---|---|---|
| Economic Nexus | Sales exceed $100K (or 200 transactions) delivered into the state | Yes — on Amazon.com orders | None on Amazon orders; full obligation on non-marketplace sales |
| Physical Nexus (FBA Inventory) | Inventory stored in an Amazon fulfillment center in the state | No — only covers Amazon.com orders | Register, collect, file, and remit on all non-marketplace sales |
Economic nexus is triggered by sales volume — when your deliveries into a state exceed its dollar or transaction threshold (typically $100,000 or 200 transactions). For Amazon-only sellers, this trigger is largely handled by Amazon's marketplace facilitator remittance. Amazon counts these sales, collects tax, and remits to the state.
Physical nexus is triggered by tangible property in a state. Under traditional nexus doctrine (predating the 2018 South Dakota v. Wayfair decision), having inventory, employees, or property in a state creates a tax obligation. When Amazon stores your FBA inventory in a warehouse in Florida, your goods are physically present in Florida. That is textbook physical nexus. It does not matter that Amazon owns the warehouse — your property is there, and most states treat that as sufficient physical presence to create nexus for the inventory owner.
The critical distinction: Amazon's marketplace facilitator status covers sales made through Amazon.com. Physical nexus from FBA inventory creates obligations on all sales into that state from any channel. These two concepts operate on parallel tracks. Having one does not satisfy, reduce, or eliminate the other.

States with Amazon Fulfillment Centers and What Physical Nexus Means
Amazon operates fulfillment centers in over 25 states. If your FBA inventory has been stored in any of these locations — even temporarily, even without your knowledge — you may have physical nexus in that state. Below are the Tier A states plus other major FBA states and what physical nexus means in each:
| State | Amazon FC Presence | FBA Inventory = Physical Nexus? | Non-Marketplace Obligation |
|---|---|---|---|
| Florida | Multiple FCs (e.g., TPA1, JAX2, MCO1) | Yes | 6% state rate + county surtax on all non-marketplace sales delivered into FL |
| Pennsylvania | Multiple FCs (e.g., AVP1, MDT1, PHL4) | Yes | 6% state rate + 2% Philadelphia local tax (if applicable) on non-marketplace sales into PA |
| Georgia | Multiple FCs (e.g., ATL6, ATL8, SAV3) | Yes | 4% state rate + local option tax on non-marketplace sales into GA |
| Arizona | Multiple FCs (e.g., PHX3, PHX5, TUS2) | Yes | TPT at state + city rates on non-marketplace sales into AZ |
| North Carolina | Multiple FCs (e.g., CLT2, RDU1) | Yes | 4.75% state rate + 2.25% local rate on non-marketplace sales into NC |
| Texas | Major hub (e.g., DFW6, HOU2, SAT1) | Yes | 6.25% state rate + up to 2% local on non-marketplace sales into TX |
| California | Major hub (e.g., ONT2, SBD1, LAX9) | Yes | 7.25% base rate + district taxes on non-marketplace sales into CA |
| New Jersey | Multiple FCs (e.g., EWR4, EWR9) | Yes | 6.625% flat rate on non-marketplace sales into NJ |
This is not an exhaustive list. Amazon operates fulfillment infrastructure in Indiana, Kentucky, Tennessee, Illinois, Michigan, Washington, and many other states. The key principle is consistent: if Amazon stored your inventory there, you likely have physical nexus there. The fact that Amazon remits sales tax on Amazon.com orders in that state does not address your obligations on non-Amazon sales.

$0 in Direct Sales but FBA Inventory in a State — Do You Still Need to Register?
This is the question that trips up more FBA sellers than any other. The scenario: you sell exclusively through Amazon. Amazon handles 100% of your sales tax collection and remittance as a marketplace facilitator. You have no Shopify store, no direct website sales, no wholesale accounts. But your FBA inventory sits in warehouses across eight states. Do you need to register in all eight?
The strict legal answer is yes. Physical nexus creates a registration obligation independent of sales volume or marketplace facilitator coverage. Your inventory in a state means you have a tax presence in that state, and most state statutes require any entity with nexus to register for a sales tax permit. The fact that your current tax liability is $0 (because Amazon remits on all your sales) does not eliminate the registration requirement — it only means your filed returns would show $0 due.
Why Registration Matters Even at $0 Liability
- Future channel expansion: If you launch a Shopify store, start selling on your own website, or take wholesale orders, you will owe sales tax in every state where you already have physical nexus — immediately, from the first transaction. Being already registered means you can collect from day one instead of scrambling to register after the fact.
- Marketplace facilitator coverage gaps: Not every marketplace qualifies as a facilitator in every state. If you sell on a smaller platform that does not remit, those sales in states where you have FBA inventory are your direct obligation.
- State audit protection: Being registered and filing $0 returns demonstrates compliance. If a state audits you, a history of filed returns — even at $0 — is far better than no registration at all.
- The cost of not registering now: If you expand to Shopify in two years and realize you should have been registered in six states the entire time, you face potential back-tax assessments from the date physical nexus was first established — which could be years earlier.
Practical reality vs. strict compliance: Many FBA-only sellers with no non-marketplace sales choose not to register in every state where inventory is stored, arguing that registration serves no practical purpose when tax liability is $0. This is a calculated risk. The downside is limited while you remain Amazon-only, but it creates retroactive exposure the moment you add any other sales channel. If you take this approach, document your reasoning and set a trigger to register immediately if you ever begin non-marketplace selling.
Voluntary Disclosure Programs for Sellers with Years of Unfiled Returns
If you have been selling through multiple channels — Amazon plus Shopify, your own website, or wholesale — while FBA inventory created physical nexus in states where you never registered, you likely have unfiled returns and uncollected tax exposure. Going directly to a state and registering is not the recommended first step. Here is why:
When you register with a state, the department of revenue can see that you are a new registrant. Many states routinely review new registrations to determine whether the seller should have registered earlier. If the state determines you had physical nexus three years ago and are just now registering, it can assess back taxes, penalties, and interest for the full period — potentially a significant sum depending on your non-marketplace sales volume.
| Approach | Lookback Period | Penalties | Interest | Recommended? |
|---|---|---|---|---|
| Register directly (no VDA) | Full statute of limitations (often 7-10 years) | Full penalties apply | Full interest from original due date | No — if you have prior exposure |
| Voluntary Disclosure Agreement (VDA) | Typically 3-4 years | Waived or significantly reduced | Usually still owed but on shortened period | Yes — the standard approach for prior exposure |
How to initiate a VDA: You can approach each state individually through its voluntary disclosure program, or use the Multistate Tax Commission's (MTC) National Nexus Program, which allows you to file a single anonymous application that covers multiple states simultaneously. The MTC process lets you disclose without revealing your identity until terms are agreed upon — protecting you from being flagged for audit before the agreement is in place.
VDA Process Overview
- Step 1: Determine your nexus exposure — identify every state where FBA inventory created physical nexus and you had unfiled non-marketplace sales obligations.
- Step 2: Engage a sales tax professional or use the MTC's National Nexus Program to submit an anonymous inquiry to each state.
- Step 3: Negotiate terms — the state agrees to a limited lookback period (typically 3-4 years) and penalty waiver in exchange for your voluntary disclosure and payment of back taxes plus interest.
- Step 4: Sign the agreement, file back returns for the agreed-upon period, and pay the assessed amount.
- Step 5: Register going forward and begin collecting and remitting on all non-marketplace sales in the state.

How to Track Your Amazon Fulfillment Center Inventory Placement
You cannot manage physical nexus exposure without knowing where Amazon is storing your inventory. Amazon provides several reports that let you track inventory placement across its fulfillment network. The most important is the FBA Inventory Ledger.
Step-by-Step: Using the FBA Inventory Ledger for Nexus Analysis
- 1. Access the report: In Seller Central, go to Reports > Fulfillment > Inventory Ledger. Select “Detailed View” and set the date range to the tax period you need to evaluate (e.g., the previous calendar year or trailing 12 months).
- 2. Identify fulfillment center codes: Each row in the report includes a fulfillment center ID — a 3-4 character code like TPA1 (Tampa, FL), AVP1 (Scranton, PA), or ATL6 (Atlanta, GA). These codes indicate the physical location where your inventory was stored.
- 3. Map codes to states: Cross-reference each fulfillment center code with its state location. Amazon does not provide an official public directory, but the codes are well-documented by the seller community. The first three characters typically correspond to the nearest airport code (TPA = Tampa, FL; PHX = Phoenix, AZ; MDW = Chicago, IL).
- 4. Build a state-by-state nexus calendar: For each state, note the earliest and latest dates your inventory was present. This defines your nexus period in that state — the window during which you had physical nexus and potentially owed tax on non-marketplace sales.
- 5. Cross-reference with non-marketplace sales: Compare your nexus calendar with your non-Amazon sales by state and period. Any non-marketplace sales delivered into a state during a period when you had FBA inventory there represent potential tax liability.
| Amazon Report | What It Shows | Use for Nexus Analysis |
|---|---|---|
| FBA Inventory Ledger | Daily inventory snapshots by fulfillment center | Primary tool — shows which FCs held your inventory and when |
| Inventory Event Detail | Every unit movement (receipts, transfers, shipments) | Granular view of when inventory arrived at and left each FC |
| Monthly Storage Fee Report | Cubic feet of storage by fulfillment center | Confirms physical presence — if you were charged storage fees at a FC, your inventory was there |
Record retention: Download and archive these reports regularly. Amazon's Seller Central only retains detailed inventory data for a limited time. If you need to reconstruct your nexus history for a voluntary disclosure or audit response three years from now, you will need these records. Save them in a structured format — organized by year and quarter — with a clear mapping of fulfillment center codes to state locations.

Frequently Asked Questions
No. Marketplace facilitator status and physical nexus are two completely separate legal concepts. Amazon's marketplace facilitator status means Amazon collects and remits sales tax on orders placed through Amazon.com. Physical nexus from FBA inventory means you have a tax presence in that state for all sales channels — your Shopify store, your own website, eBay orders not covered by eBay's facilitator remittance, wholesale transactions, and any other non-marketplace revenue. Amazon's facilitator coverage does not cancel, override, or reduce your physical nexus. You have both simultaneously, and each creates its own obligations.
