Amazon FBA Sales Tax: How to Register, Collect, and Remit in Multiple States
Amazon collects sales tax in marketplace facilitator states, but that does not eliminate your obligations. You still must register, file returns, and maintain records in states where you have nexus. Here is how nexus works with FBA inventory, what Amazon handles, and what you must do yourself.

Why Amazon FBA Creates Multi-State Tax Obligations
When you use Fulfillment by Amazon (FBA), Amazon distributes your inventory across its warehouse network. Your products may be stored in warehouses in Texas, California, New Jersey, Illinois, and other states — often without you choosing or even knowing which states hold your inventory at any given time.
This matters because many states consider the physical presence of your inventory in their state to be sufficient to create sales tax nexus — a legal connection that triggers the obligation to collect and remit sales tax on sales made to customers in that state.
If you sell through Amazon FBA, you likely have nexus in multiple states simply because Amazon placed your inventory there. This is not optional. It is not a gray area. Inventory presence equals physical nexus in the majority of US states.
For a detailed explanation of how nexus works with FBA inventory placement, see What Is Sales Tax Nexus: Amazon FBA Inventory.
Two Types of Nexus That Apply to FBA Sellers
Physical Nexus (Inventory Presence)
If your products are physically stored in a state's FBA warehouse, you have physical nexus in that state. The major states where Amazon operates fulfillment centers include California, Texas, New Jersey, Pennsylvania, Illinois, Indiana, Kentucky, Arizona, Tennessee, and many others.
Amazon does not guarantee which states will hold your inventory. It moves inventory between warehouses based on demand forecasting. This means your nexus footprint can change from month to month.
Economic Nexus (Sales Thresholds)
Even without physical inventory presence, most states have established economic nexus thresholds. If your sales into a state exceed a certain amount (commonly $100,000 in revenue or 200 transactions per year), you have economic nexus in that state.
For high-volume FBA sellers, economic nexus often overlaps with physical nexus. You may have nexus in a state through both inventory presence and sales volume.
What Amazon Marketplace Facilitator Laws Cover
As of 2026, all 45 states with a sales tax (plus Washington DC) have marketplace facilitator laws. These laws require Amazon (as the marketplace facilitator) to collect and remit sales tax on sales made through its platform.
This means Amazon automatically calculates, collects, and remits sales tax on your FBA orders in these states. The tax appears on the customer's receipt, and Amazon sends the collected tax to the appropriate state tax authority.
What this covers:
Sales tax calculation based on the customer's delivery address
Collection of the correct state, county, and local tax rates
Remittance of collected tax to each state's tax authority
Amazon files marketplace facilitator returns in these states
What this does NOT cover:
Your obligation to register for a sales tax permit in nexus states
Filing your own sales tax returns (required in many states even if Amazon collected the tax)
Sales made through channels outside Amazon (your own website, other marketplaces)
Use tax obligations on inventory you consume or use
Record keeping and audit documentation
Why You Still Must Register and File
This is the point most FBA sellers misunderstand. Amazon collecting sales tax does not eliminate your registration and filing obligations. Here is why:
Registration requirement. Many states require any business with nexus to hold a valid sales tax permit. Operating with nexus but without a permit can result in penalties, even if the correct amount of tax was collected by Amazon. Some states view unregistered nexus as operating without a license.
Filing requirement. Even when Amazon collects and remits 100% of your sales tax, many states require you to file a return showing your sales activity. In some states, this is a zero-dollar return (since Amazon already remitted). In other states, you must report your gross sales and show the marketplace facilitator collection. Failing to file can trigger notices, penalties, and interest.
Non-Amazon sales. If you sell through any channel besides Amazon — your own Shopify store, eBay, Walmart Marketplace, or wholesale — the marketplace facilitator law may not cover those transactions. You are responsible for collecting and remitting sales tax on non-marketplace sales in your nexus states.
Audit protection. If a state audits your business, you need documentation showing you were registered, filed returns, and can account for all sales and tax collected. Without registration and filing records, an audit becomes significantly more difficult to defend.
How to Determine Your Nexus States
To identify where you have sales tax nexus:
1. Check Amazon's FBA inventory reports. Amazon provides reports showing which states and fulfillment centers held your inventory during each period. Download these regularly.
2. Review your sales by state. Amazon provides sales reports broken down by ship-to state. Compare your sales volume to each state's economic nexus thresholds.
3. Map both nexus types. Create a list of states where you have (a) physical nexus from inventory, (b) economic nexus from sales volume, or (c) both.
4. Consult a sales tax professional. Nexus analysis can be complex, especially when inventory moves between states. A professional can confirm your nexus footprint and advise on registration priorities.
Your nexus analysis is not a one-time exercise. Because Amazon moves inventory and your sales patterns shift, you should review your nexus exposure quarterly at minimum.
The Registration Process
Once you identify your nexus states, you must register for a sales tax permit in each one. The process varies by state but generally involves:
Applying through the state's Department of Revenue or Tax Commission website
Providing your LLC formation details, EIN, and business address
Describing your business activity (e-commerce, retail, etc.)
Specifying whether you have physical presence or economic nexus
Receiving a sales tax permit number (usually within 1-3 weeks for online applications)
Some states require registration before you begin making sales. Others allow retroactive registration. Timing matters because late registration can trigger back-filing requirements and penalties.
Cost of registration: Most states charge no fee for sales tax permit registration. A few charge nominal fees ($10-50).
Filing Sales Tax Returns
After registration, you must file sales tax returns according to each state's schedule. Filing frequency depends on your sales volume in that state:
**Monthly filing**: for sellers with high volume in the state (typically over $100-300/month in tax collected)
**Quarterly filing**: for moderate volume
**Annual filing**: for low volume
Each return reports:
Your gross sales in the state
Exempt sales (if any)
Taxable sales
Tax collected by marketplace facilitators (Amazon)
Tax you collected directly (non-Amazon sales)
Tax due (usually zero if all sales were through Amazon in marketplace facilitator states)
Even if the amount due is zero, you must file the return. Failure to file a zero return is treated the same as failure to file — it generates notices and can result in estimated assessments.
Multi-State Automation Tools
Filing sales tax returns in 10, 20, or more states manually is impractical. Most FBA sellers use automation tools:
TaxJar provides automated filing in all US states. It integrates with Amazon, Shopify, and other platforms to pull sales data, calculate obligations, and file returns on your behalf. Pricing starts around $19/month for basic plans and scales with transaction volume.
Avalara offers similar automation with deeper enterprise capabilities. It handles calculation, filing, and exemption certificate management. Pricing is typically higher than TaxJar, starting around $50/month.
Vertex and Sovos serve larger businesses with complex multi-state and multi-channel operations.
For most FBA sellers doing under $1 million in annual revenue, TaxJar or Avalara at $200-500/month covers the full filing cycle across all nexus states.
Alternatively, you can hire a CPA or sales tax firm to handle filings manually. Cost varies by state count:
5 states: approximately $100-250/quarter
10 states: approximately $200-500/quarter
20+ states: approximately $400-1,000/quarter or automation is more cost-effective
Wyoming-Specific Considerations
Wyoming has no state income tax, which is one reason it is popular for LLC formation. However, Wyoming does have sales tax (4% state rate, plus local rates). If your LLC is formed in Wyoming and you have nexus there (through inventory or sales threshold), you must register and file in Wyoming like any other state.
Wyoming's economic nexus threshold is $100,000 in sales or 200 transactions per year. If your FBA sales shipped to Wyoming customers exceed these thresholds, you have economic nexus regardless of whether Amazon stores inventory there.
Record-Keeping Requirements
States can audit sales tax compliance going back 3-4 years (varies by state). You must maintain:
Monthly or quarterly sales reports by state from Amazon Seller Central
FBA inventory placement reports showing which states held inventory
Sales tax return copies for all filed returns
Registration confirmations and permit numbers for each state
Records of any exempt sales or resale certificates received
Non-Amazon sales records, matched to the states where sales occurred
Store these records digitally with clear organization by state and period. In an audit, the state will request specific records for specific periods. Being able to produce them quickly demonstrates compliance.
Common Mistakes FBA Sellers Make
Assuming Amazon handles everything. Amazon collects and remits, but you must register and file. These are separate obligations.
Ignoring states where you have no direct sales. If Amazon stores your inventory in a state, you have nexus there even if you made zero sales to customers in that state. You may still need to register.
Filing late or not at all. Late filing generates automatic penalties in most states ($50-250 per late return, plus interest). Multiple missed filings can result in estimated assessments where the state guesses your liability — always higher than actual.
Not tracking inventory placement. Amazon moves inventory without notice. Download FBA inventory reports monthly to track which states hold your products.
Mixing up nexus types. Physical nexus (inventory) and economic nexus (sales volume) can overlap or exist independently. Track both.
When to Get Professional Help
You should work with a sales tax professional if:
You sell in more than 5 states
You have non-Amazon sales channels
You received a notice from a state tax authority
You have not been filing and need to catch up (voluntary disclosure may be available)
Your annual revenue exceeds $250,000
A qualified CPA or sales tax firm can conduct a nexus study, handle registrations, set up automated filing, and represent you in audits. The cost of professional help is almost always less than the cost of non-compliance penalties. For a complete calendar of tax deadlines, see Tax Calendar for Foreign-Owned Wyoming LLC.
