Marketplace facilitator tax is defined as a legal requirement that shifts sales tax collection and remittance from individual sellers to the online platform processing the sale. Every one of the 45 U.S. states with a statewide sales tax, plus Washington D.C., now has these laws in place. Missouri was the last state to adopt them, effective january 1, 2023. For resellers on Amazon, Etsy, or eBay, this means the platform collects and remits sales tax on your marketplace transactions automatically. The catch: your obligations don't end there.
What is marketplace facilitator tax and how does it work?
Marketplace facilitator tax law designates the platform as the "seller of record" for sales tax purposes on transactions it processes. The marketplace collects tax from the buyer at checkout, then remits it directly to each state. You, the seller, never touch that money.
This shift centralized tax collection at the platform level, which dramatically reduced the compliance burden for small sellers who sell exclusively on third-party platforms. Think of it like a farmers' market organizer who handles permits and fees on behalf of every vendor in the stalls. The organizer takes care of the paperwork so vendors can focus on selling.
The key word is "marketplace transactions." The law covers only sales processed through the platform. Any sale you make outside that platform is entirely your responsibility. That distinction is what catches most resellers off guard.
How these laws affect your sales tax collection responsibilities
The practical effect for most Amazon or Etsy sellers is straightforward: you do not collect or remit sales tax on orders the marketplace processes. The platform handles it automatically.
Your remaining responsibilities fall into three areas:
- Direct-to-consumer sales: Sales through your own Shopify store, website, or social media are not covered. You must collect, track, and remit tax on those yourself.
- Wholesale and B2B sales: Sales to other businesses or retailers outside the marketplace carry their own tax rules and exemption certificate requirements.
- Product Tax Codes (PTCs): You are still responsible for assigning the correct PTCs to your listings. If a product is misclassified as tax-exempt when it is taxable, the platform may under-collect, and the liability can fall back on you.
Marketplace settlement reports label each transaction as "MarketplaceFacilitator" to confirm the platform collected and remitted the tax. Review these reports every month. Gaps in that label are a red flag worth investigating before an auditor finds them first.
Pro Tip: Download your settlement report at the end of each month and filter for any transactions not labeled "MarketplaceFacilitator." Those are the sales where you may still owe tax.
How does nexus affect your tax obligations as a reseller?
Nexus is the legal connection between your business and a state that requires you to collect and remit sales tax there. Two types matter most for resellers: economic nexus and physical nexus.
Economic nexus is triggered by crossing a state's sales volume or transaction threshold. Most states follow the South Dakota v. Wayfair standard of $100,000 in sales or 200 transactions in a state per year. Here is where it gets nuanced:
- Check whether marketplace sales count toward your threshold. Many states exclude marketplace sales from your economic nexus calculation because the platform already remits tax on those. California and Louisiana are notable exceptions that include them.
- Track your direct sales separately. Your Shopify or wholesale revenue counts toward economic nexus thresholds in every state where you sell directly.
- Register before you cross the threshold. Most states require registration before your first taxable sale after you hit the threshold, not after.
- Review thresholds annually. States adjust rules. A state that excluded marketplace sales last year may include them this year.
Physical nexus is a separate and often overlooked trigger. Storing inventory in a state through Amazon FBA fulfillment centers creates physical nexus in that state immediately, regardless of your sales volume. Amazon distributes FBA inventory across its network, which means you may have physical nexus in states you have never consciously targeted. Physical nexus can also create obligations beyond sales tax, including income tax, franchise tax, or gross receipts tax, depending on the state.
Pro Tip: Use Amazon's Inventory Event Detail report to identify which states currently hold your FBA inventory. Cross-reference that list against your state tax registrations quarterly.
State-by-state variations in marketplace facilitator laws
Every sales-tax state has facilitator laws, but the details vary enough to create real compliance risk. The five states without a statewide sales tax (Alaska, Delaware, Montana, New Hampshire, and Oregon) have no facilitator obligations.
Here is a snapshot of key state rules resellers encounter most often:
| State | Economic nexus threshold | Marketplace sales count toward nexus? | Zero-return required? |
|---|---|---|---|
| California | $500,000 | Yes | Yes, if registered |
| Texas | $500,000 | No | Yes, if registered |
| Florida | $100,000 | No | No |
| New York | $500,000 + 100 transactions | No | Yes, if registered |
| Illinois | $100,000 or 200 transactions | No | Yes, if registered |
Some states require sellers to register for a sales tax permit and file informational or zero-dollar returns even when the marketplace collects every cent of tax on their behalf. New York and Illinois are clear examples. Skipping those filings triggers penalties even though you owe no actual tax. That is a costly mistake that is entirely avoidable.
California's inclusion of marketplace sales in the nexus threshold is the most consequential variation for high-volume Amazon sellers. A seller doing $400,000 in Amazon sales and $150,000 in direct sales has crossed California's $500,000 threshold and must register, even though Amazon remits the tax on the Amazon portion.
Managing sales tax when you sell across multiple channels
Marketplace facilitator laws cover only platform sales. The moment you sell through your own store, at trade shows, or wholesale, you carry full tax responsibility for those transactions.
Multi-channel sellers face the greatest compliance complexity. Here is what the best-run operations do consistently:
- Separate your revenue streams. Track marketplace sales and direct sales in different buckets. Mixing them makes reconciliation and filing far harder.
- Register in states where you have nexus for direct sales. Even if Amazon handles your marketplace tax, your Shopify store may create economic nexus in states where you have no registration.
- Reconcile monthly, not annually. Monthly reconciliation of settlement reports against your tax filings is the single most recommended practice for audit defense.
- Keep exemption certificates current. If you sell wholesale, collect and store resale certificates from every buyer. Expired or missing certificates are a primary audit trigger.
The biggest risk is assuming the marketplace handles everything. Many sellers make this mistake and discover the gap only when a state sends a notice. By then, penalties and interest have already compounded.
Pro Tip: Set a calendar reminder on the first of each month to pull your marketplace settlement report, your direct sales report, and your current state registrations. Compare all three before filing anything.
How to stay compliant with marketplace facilitator tax laws
Compliance comes down to four concrete steps. Follow them consistently and you reduce audit risk to a manageable level.
- Register in every state where you have nexus. Physical nexus from FBA inventory requires registration regardless of sales volume. Economic nexus from direct sales requires registration once you cross the threshold.
- File required returns, even zero-dollar ones. Failure to file informational returns in states that require them carries penalties independent of any tax owed. Check each state's requirements after you register.
- Use platform reports as your audit evidence. The "MarketplaceFacilitator" label in settlement reports is your proof that the platform collected and remitted tax. Save these reports for at least four years, which covers most state audit windows.
- Consult a sales tax professional when you expand. Adding a new sales channel, a new warehouse, or a new state market changes your obligations. A one-hour consultation with a CPA who specializes in e-commerce sales tax costs far less than penalties from non-compliance, which commonly run 5–10% of tax due per period, compounded over multiple years.
The sellers who get audited and walk away clean are the ones who kept records, filed on time, and never assumed the marketplace covered everything.
Key Takeaways
Marketplace facilitator tax laws shift sales tax collection to platforms for marketplace transactions, but sellers remain fully responsible for direct sales, nexus tracking, and required state filings.
| Point | Details |
|---|---|
| Platforms collect, not sellers | Marketplaces like Amazon remit sales tax on platform transactions automatically. |
| Direct sales are your responsibility | Shopify, wholesale, and social media sales require separate tax collection and filing. |
| FBA creates physical nexus | Inventory stored in Amazon fulfillment centers triggers state tax obligations immediately. |
| Some states require zero returns | Filing informational returns is mandatory in several states even when no tax is owed. |
| Monthly reconciliation protects you | Reviewing settlement reports each month is the most effective defense against audits. |
Why marketplace facilitator laws are simpler than sellers think, until they aren't
I've watched sellers breathe a sigh of relief when they learn Amazon handles their sales tax. That relief is earned for pure marketplace sellers. The law genuinely removed a massive administrative burden from small resellers who would otherwise need to register, collect, and file in dozens of states.
The problem shows up the moment you add a second channel. A Shopify store, a wholesale account, a booth at a trade show. Suddenly you have economic nexus calculations to run, separate registrations to maintain, and filings that have nothing to do with your Amazon settlement report. The sellers who get into trouble are almost always multi-channel sellers who applied the "Amazon handles it" logic to their entire business.
The other thing I'd push back on is the idea that facilitator laws are static. States have been adjusting their rules since South Dakota v. Wayfair in 2018, and they haven't stopped. California's decision to include marketplace sales in the nexus threshold was a significant change that caught many sellers off guard. Staying current means checking state rules at least once a year, not just when you first register.
The sellers I respect most treat tax compliance the same way they treat inventory management: as a system, not a one-time task. Build the habit of monthly reconciliation, keep your registrations current, and get professional advice when you expand. That approach costs far less than cleaning up a multi-year audit.

FAQ
What is marketplace facilitator tax?
Marketplace facilitator tax is a legal requirement that makes online platforms, not individual sellers, responsible for collecting and remitting sales tax on marketplace transactions. All 45 U.S. states with a statewide sales tax have these laws in place.
Does Amazon collect sales tax on my behalf?
Yes. Amazon acts as a marketplace facilitator and collects and remits sales tax on all orders processed through its platform. Your settlement report will label these transactions as "MarketplaceFacilitator" to confirm collection.
Do I still need to register for sales tax if Amazon collects it?
Yes, in many states. Some states require sellers to register and file zero-dollar or informational returns even when the marketplace remits all sales tax. Skipping these filings triggers penalties regardless of tax owed.
Does FBA inventory create a tax obligation in other states?
Yes. Storing inventory in Amazon FBA fulfillment centers creates physical nexus in those states immediately. Physical nexus triggers state tax obligations independent of your sales volume or economic nexus thresholds.
Are my Shopify sales covered by marketplace facilitator laws?
No. Marketplace facilitator laws apply only to sales processed through the marketplace platform. Sales through your own website, Shopify store, or any direct channel are your full responsibility for tax collection and remittance.
