Selling online became significantly easier when marketplaces such as Amazon, Etsy, eBay, and Walmart gave businesses access to millions of customers without requiring them to build their own ecommerce infrastructure.
Sales tax did not become equally simple.
A seller may make the exact same product sale through:
Amazon
Etsy
eBay
Walmart Marketplace
Shopify
WooCommerce
Its own physical store
and have a different sales tax collection responsibility depending on which channel processed the transaction.
This happens because of Marketplace Facilitator Laws.
These laws generally shift responsibility for calculating, collecting, and remitting sales tax on qualifying marketplace transactions from the individual marketplace seller to the marketplace itself.
That sounds simple:
“Amazon collects the sales tax, so I don't need to worry about sales tax anymore.”
Unfortunately, that conclusion can be wrong.
Marketplace facilitator laws can simplify collection on marketplace transactions, but they do not automatically eliminate:
Economic nexus
Physical nexus
Sales tax registration
Sales tax returns
Direct website collection
Product taxability
Resale certificates
Drop shipping documentation
Shipping taxability
Use tax
Recordkeeping
Reconciliation
For multichannel ecommerce businesses, the correct question is therefore not:
“Does Amazon collect sales tax?”
The better question is:
“Which party is responsible for each sales tax obligation on each sales channel in each state?”
This 2026 guide explains how marketplace facilitator sales tax works and what Amazon, Etsy, eBay, and Walmart sellers should understand before assuming their sales tax obligations have been completely outsourced.
Important: Marketplace facilitator, economic nexus, registration, filing, and product taxability rules vary by state and transaction. This guide provides general information and does not constitute legal or tax advice.
Quick Answer: What Is a Marketplace Facilitator?
A marketplace facilitator is generally a business that:
Provides a marketplace where third-party sellers can offer products or services;
Facilitates transactions between those sellers and customers; and
Processes, collects, or otherwise controls payment for the transaction.
Examples include:
Amazon
Etsy
eBay
Walmart Marketplace
Under marketplace facilitator laws, the platform can become responsible for collecting and remitting sales tax on taxable transactions facilitated through its marketplace.
Streamlined Sales Tax describes a marketplace facilitator similarly: a business that owns, operates, or controls a physical or electronic marketplace, facilitates third-party sales, and collects payment from purchasers directly or indirectly.
Marketplace Facilitator vs. Marketplace Seller
These terms describe two different businesses.
Marketplace Facilitator
The platform.
Examples:
Amazon Etsy eBay Walmart
Marketplace Seller
The business actually selling the merchandise through that platform.
Example:
Suppose ABC Electronics LLC lists headphones on Amazon.
Amazon is the:
Marketplace Facilitator
ABC Electronics is the:
Marketplace Seller
The customer purchases:
Headphones: $200 Sales Tax: $14 Total: $214
When marketplace facilitator law applies, Amazon may calculate and collect the $14 and remit it directly to the appropriate tax authority.
ABC Electronics receives the proceeds of the transaction according to Amazon's settlement process without becoming responsible for remitting that same $14 again.
But ABC Electronics can still have other sales tax obligations.
That distinction is crucial.
Why Marketplace Facilitator Laws Exist
After the U.S. Supreme Court's South Dakota v. Wayfair decision allowed states to impose sales tax collection obligations based on economic activity rather than only physical presence, ecommerce sales tax compliance expanded dramatically.
States faced a practical problem.
Without marketplace facilitator laws, a state might need to enforce sales tax requirements against hundreds of thousands of individual sellers operating through large marketplaces.
Marketplace facilitator laws concentrate much of that collection responsibility at the platform level.
Instead of requiring the state to collect from:
Seller A Seller B Seller C Seller D Seller E …and thousands more
the state can require the marketplace facilitating those transactions to collect and remit the tax.
By 2026, marketplace facilitator rules are firmly established across U.S. jurisdictions that impose broad sales, use, or similar transaction taxes, although definitions, thresholds, filing requirements, and seller obligations still vary.
The Most Important Rule: Marketplace Collection Is Not the Same as Complete Sales Tax Compliance
Imagine a business sells:
Amazon sales: $400,000 Shopify sales: $300,000 Wholesale sales: $150,000 Phone orders: $50,000
Total sales:
$900,000
Amazon may handle sales tax on the $400,000 of marketplace sales.
But who handles tax on the remaining:
$500,000?
Potentially the seller.
That depends on:
Customer destination
Economic nexus
Physical nexus
Product taxability
Customer exemptions
State registration
Marketplace laws
This is why multichannel sellers need to maintain separate sales-tax logic for:
Marketplace Sales
and
Direct Sales
How Amazon Handles Marketplace Sales Tax
Amazon operates as a marketplace facilitator for third-party marketplace transactions where applicable law assigns it the collection responsibility.
Amazon describes its Marketplace Tax Collection system as one under which Amazon calculates, collects, remits, and refunds sales and use tax on qualifying marketplace orders shipped to jurisdictions that have enacted marketplace facilitator or similar laws.
For many Amazon sellers, that means:
Customer purchases product on Amazon
Amazon calculates the applicable tax.
Customer pays Amazon
Amazon collects the tax.
Amazon remits the marketplace tax
The seller generally does not remit that same marketplace tax separately.
However, this does not necessarily eliminate the seller's need to:
Track nexus
Maintain registrations
File returns where required
Report marketplace sales where required
Collect tax on direct website sales
Maintain resale certificates
Review Amazon tax reports
Reconcile marketplace settlements
An Amazon seller therefore should never assume:
Amazon Sales Tax Collection = No Sales Tax Compliance
How Etsy Handles Marketplace Sales Tax
Etsy also automatically calculates, collects, and remits U.S. sales tax when applicable marketplace facilitator laws require it.
Etsy states that its tax calculation depends on the applicable taxing jurisdiction and how the product is listed.
That final point is particularly important.
A marketplace tax engine needs information.
The platform may need to determine:
What is being sold?
Is it tangible personal property?
Is it clothing?
Is it food?
Is it a digital product?
Is the customer exempt?
Where is the customer located?
Is shipping taxable?
If the seller's listing or tax classification is wrong, the resulting tax calculation can also be wrong.
Therefore:
Automation does not eliminate the need for accurate product setup.
How eBay Handles Marketplace Sales Tax
eBay similarly calculates, collects, and remits sales tax on transactions where applicable law requires eBay to act as the marketplace facilitator.
eBay's current Seller Center lists marketplace facilitator collection across numerous U.S. jurisdictions and explains that sellers cannot opt out of eBay's required marketplace collection for qualifying transactions.
That means the seller should not attempt to independently add a duplicate sales tax charge to a transaction already handled under eBay's marketplace tax system.
But the seller may still have separate responsibilities for:
Off-eBay sales
Physical presence
Sales tax registrations
Filing obligations
Exempt sales documentation
Business purchases
Use tax
How Walmart Marketplace Handles Sales Tax
Walmart Marketplace also operates as a marketplace facilitator.
Walmart's current tax policy states that Walmart acts as the taxpayer and seller of record with respect to applicable Marketplace Facilitator Law taxes on third-party Marketplace sales and collects those taxes from customers for remittance to the applicable jurisdictions.
However, Walmart includes an important distinction:
Not every tax or fee is necessarily an MFL Tax.
Certain other taxes or fees can potentially remain the responsibility of the retailer.
Walmart also requires sellers to select appropriate tax classifications and, for shipping, appropriate sales-tax codes where applicable.
This reinforces an important principle:
The marketplace tax engine can only work correctly when the underlying product and transaction information is correct.
Marketplace Sales vs. Direct Sales
This is probably the most important section for multichannel sellers.
Suppose an ecommerce company makes annual sales into State X:
Amazon: $75,000 eBay: $25,000 Shopify: $90,000
Total:
$190,000
Amazon and eBay may collect tax on their marketplace transactions.
But what happens to the $90,000 of Shopify sales?
The seller must determine:
Whether marketplace sales count toward State X's economic nexus threshold;
Whether its direct sales independently exceed the threshold;
Whether any physical nexus exists;
Whether registration is required;
Whether Shopify sales are taxable;
Which rate applies.
This analysis must be performed state by state.
For our complete nexus analysis, see:
Economic Nexus Thresholds by State: 2026 Sales Tax Guide for Online Sellers.
Do Marketplace Sales Count Toward Economic Nexus?
Sometimes.
And this is one of the biggest traps in ecommerce sales tax.
States do not all treat marketplace sales identically when determining whether an individual seller exceeds an economic nexus threshold.
Depending on the state, the threshold calculation may consider:
Marketplace sales
Direct sales
Both
Only taxable sales
Gross sales
Retail sales
Exempt sales
Current-year activity
Prior-year activity
Therefore, a seller should maintain at least two separate totals by state:
Marketplace Sales
and
Direct Sales
Do not simply look at Shopify revenue.
Do not simply look at Amazon revenue.
Look at the state's actual nexus rules.
Streamlined Sales Tax specifically maintains separate state guidance showing whether marketplace sales are included in a seller's remote-seller threshold calculation because the answer varies by jurisdiction.
Florida Example
Florida provides a particularly useful example.
Florida requires marketplace providers to collect and remit tax on qualifying marketplace sales into the state.
For a marketplace seller determining whether its own remote sales require registration, Florida generally looks at the seller's sales outside the marketplace.
A marketplace seller with physical presence in Florida, or with more than $100,000 in qualifying remote sales to Florida customers outside the marketplace, can have its own registration and collection responsibility.
When the marketplace provider certifies that it will collect and remit Florida tax, qualifying marketplace sales generally are not included on the marketplace seller's Florida return under the ordinary marketplace-provider treatment.
Example
Amazon sales into Florida: $300,000 Direct Shopify sales into Florida: $60,000 No physical presence in Florida
The seller should not automatically conclude:
“I have $360,000 in Florida sales, therefore Florida economic nexus definitely requires me to register.”
Florida's marketplace rules require examining the non-marketplace remote sales separately for this purpose.
This is exactly why generic nexus dashboards can be dangerous if they do not apply state-specific marketplace rules.
New York Example
New York handles the marketplace seller relationship differently in several respects.
New York requires marketplace providers to collect state and local sales tax on taxable tangible personal property they facilitate for delivery to New York.
However, a marketplace seller that independently meets New York's vendor-registration requirements can still be required to register and file periodic returns even though the marketplace provider collected the tax on facilitated sales.
Registered sellers generally report qualifying marketplace-facilitated tangible personal property sales on their New York returns as nontaxable sales and retain the marketplace provider's certification or qualifying agreement.
So:
Marketplace collected the tax does not necessarily mean: Seller never files a New York sales tax return.
Texas Example
Texas also places customer-facing marketplace sales tax collection on the marketplace provider when the provider has certified that it is assuming the responsibility.
Texas expressly identifies Amazon, eBay, Walmart Marketplace, and Etsy as marketplace-provider examples.
A marketplace seller generally is not responsible for collecting and remitting Texas sales tax on marketplace sales when the provider has certified that it will do so.
But the seller still needs to analyze:
Texas physical presence
Direct Texas sales
Other taxable activities
Registration requirements
Recordkeeping
Marketplace collection does not erase the rest of the business.
Marketplace Facilitator Laws Do Not Make Products Taxable or Exempt
Marketplace laws determine primarily:
Who must collect the tax.
They do not create one nationwide rule determining: what is taxable.
A marketplace might sell:
Clothing
Food
Computers
Books
Digital downloads
SaaS
Supplements
Machinery
Medical products
Services
Tax treatment can differ dramatically.
An article of clothing might be taxable in one state and exempt in another.
A digital product may be taxable in one jurisdiction and exempt elsewhere.
Therefore, the marketplace still needs accurate product information.
Product Tax Codes Matter
Marketplace tax systems depend on product classification.
Imagine a seller lists:
Children's clothing
but assigns a generic taxable merchandise code.
A state that exempts certain clothing could receive an incorrect calculation.
Or imagine a taxable electronic accessory is assigned an exempt product classification.
The platform could undercollect.
Potential consequences include:
Customer complaints
Audit exposure
Tax adjustments
Marketplace corrections
Refunds
Seller liability where the error originated from seller-provided information
New York expressly provides marketplace facilitators with certain liability relief when undercollection results from incorrect or insufficient information provided by the marketplace seller.
The lesson:
Marketplace automation is not a substitute for correct product taxability.
Marketplace Sales and Shipping Tax
Shipping creates another layer.
Suppose:
Product: $100 Shipping: $15
The marketplace must determine whether tax applies to:
$100
or:
$115
depending on the destination state's rules.
Some states generally tax shipping associated with taxable merchandise.
Others can exclude qualifying separately stated shipping.
Some distinguish:
Shipping
Handling
Delivery
Freight
Seller delivery
Common carrier delivery
Platforms such as Walmart specifically maintain shipping tax classifications to help calculate the applicable tax.
For our state-by-state analysis, see:
Are Shipping Charges Taxable? Sales Tax on Shipping by State: 2026 Guide.
Marketplace Sales and Resale Certificates
Marketplace facilitator laws do not eliminate resale certificate issues.
Suppose a seller sells a product on Amazon.
The seller purchases that product from a wholesaler for:
$60
and sells it on Amazon for:
$100
Amazon may handle sales tax on:
Seller → Customer
But the seller still needs to document:
Wholesaler → Seller
as a purchase for resale when appropriate.
Otherwise, the wholesaler may charge sales tax on the $60 purchase.
Therefore:
Marketplace Facilitator Law solves the retail collection problem.
It does not necessarily solve the seller's wholesale resale documentation problem.
For verification procedures, see:
How to Verify a Resale Certificate in Every State: 2026 Guide.
Marketplace Sales and Drop Shipping
This becomes even more important when marketplace selling and drop shipping are combined.
Example:
Customer → Amazon Amazon Seller → Supplier Supplier → ships directly to Customer
Amazon may collect the customer-facing tax.
But the supplier still needs to determine whether its sale to the marketplace seller qualifies for resale.
Depending on the destination state, the supplier may require:
Home-state resale certificate
Destination-state certificate
SST certificate
MTC certificate
Local registration
Other documentation
Marketplace facilitator collection therefore does not automatically prevent your drop shipping supplier from charging you sales tax.
For the complete analysis, see:
Drop Shipping Sales Tax by State: Complete Guide for Sellers (2026).
Marketplace Sales and Use Tax
Marketplace facilitator laws focus largely on sales to customers.
Businesses must also review their own purchases.
Suppose your company buys:
Office computer: $2,000 Sales Tax: $0
through an online marketplace.
If the computer is taxable and the correct tax was not collected, the business may need to determine whether use tax is due.
Marketplace sales tax collection and business use tax therefore address opposite sides of the transaction.
For more information, see:
Sales Tax vs. Use Tax: What Businesses Need to Know in 2026.
Do Marketplace Sellers Still Need Sales Tax Permits?
Sometimes yes.
The answer depends on the state.
Potential reasons include:
Physical Presence
The seller has:
An office
Employees
Inventory
Property
A warehouse
Representatives
in the state.
Direct Sales
The seller also sells through:
Shopify
WooCommerce
Its own website
Phone orders
Wholesale invoices
Physical stores
State Filing Rules
Some states can require registered marketplace sellers to continue filing returns even when facilitated tax is remitted by the marketplace.
Existing Registration
A seller already registered in a state may have continuing filing obligations until the account is properly closed, even if future sales are entirely through a marketplace.
Never simply stop filing because Amazon started collecting tax.
That can produce:
Late notices
Estimated assessments
Penalties
Suspended registrations
Unfiled-return balances
Marketplace-Only Seller vs. Multichannel Seller
The compliance difference can be substantial.
Marketplace-Only Seller
100% of sales occur through Amazon.
Potentially simpler.
The seller must still analyze:
Physical nexus
Registration requirements
Filing requirements
Resale purchases
Use tax
Recordkeeping
but customer-facing tax collection may largely be handled by Amazon.
Multichannel Seller
Sales occur through:
Amazon Etsy eBay Walmart Shopify Wholesale
Much more complex.
Every state may require the company to separate:
Marketplace-facilitated sales from Seller-collected direct sales
Example: Multichannel Ecommerce Seller
Consider this annual activity in one state:
Amazon: $180,000 Etsy: $40,000 Shopify: $125,000 Wholesale: $25,000
Total:
$370,000
Marketplace sales:
$220,000
Direct sales:
$150,000
Possible responsibilities:
Amazon + Etsy Sales
Platforms may collect and remit marketplace tax.
Shopify + Wholesale
Seller may need to collect tax if nexus exists and the transactions are taxable.
Filing
State may still require marketplace and direct sales to appear in different locations on the seller's return.
Nexus
State-specific rules determine which sales count toward the threshold.
A seller that simply sees:
“Amazon remitted sales tax”
and stops there is missing most of the analysis.
Marketplace Facilitator Sales Tax and Refunds
Suppose a marketplace customer returns a taxable product.
Original order:
Product: $100 Sales Tax: $7 Total: $107
Because the marketplace collected the $7, the marketplace generally controls the tax adjustment or refund process for that facilitated order.
The seller should avoid independently creating an off-platform sales tax refund without understanding how the platform adjusts:
Customer payment
Marketplace tax
Seller proceeds
Platform reports
Otherwise, accounting records can become disconnected from marketplace tax reporting.
Marketplace Facilitator Laws and Tax-Exempt Customers
Marketplace transactions can also involve exempt purchasers.
Examples:
Resellers
Government entities
Nonprofits
Exempt organizations
Qualifying business purchasers
Platforms can maintain tax-exemption programs or processes to apply qualifying exemptions.
Sellers should not manually override tax simply because a customer sends them a document outside the marketplace.
The exemption should generally be processed using the platform's applicable procedure so that:
Tax calculation is adjusted
Customer payment is correct
Marketplace records are correct
Seller records reconcile
Appropriate documentation is retained
Why Marketplace Reports Matter
Marketplace sellers should retain and reconcile reports showing:
Gross sales
Refunds
Marketplace tax
Seller-collected tax, if any
Fees
Shipping
Discounts
Exempt sales
Customer destination
Marketplace facilitator status
A bank deposit alone is not enough.
Suppose:
Customer sales: $100,000 Marketplace tax collected: $7,000 Marketplace fees: $15,000 Refunds: $5,000 Net payout: $80,000
Looking only at the: $80,000 bank deposit does not tell accounting what actually happened.
Recommended Accounting Reconciliation
A good marketplace reconciliation should connect:
Marketplace Gross Sales
→ Refunds
→ Sales Tax Collected by Marketplace
→ Marketplace Fees
→ Other Adjustments
→ Net Settlement
→ Bank Deposit
This helps explain differences between:
Marketplace reports
General ledger revenue
Sales tax returns
Bank deposits
Financial statements
Marketplace-collected sales tax should not accidentally be remitted a second time merely because it appears somewhere in a settlement report.
Marketplace Sales vs. 1099-K Reporting
Another frequent source of confusion is Form 1099-K.
A 1099-K is a federal information-reporting document.
Marketplace facilitator sales tax is a state and local indirect-tax issue.
They are not the same system.
Amounts appearing on:
1099-K
Marketplace settlement reports
Sales tax returns
Bank deposits
Financial statements
may not match directly because they can reflect different concepts.
Businesses should reconcile the differences, not assume that one number must equal another.
Common Marketplace Sales Tax Mistakes
Mistake #1 — “Amazon Collects Tax, So I Don't Need to Track Nexus”
Wrong.
Direct sales and physical presence can still create obligations.
Mistake #2 — Ignoring Shopify Sales
Marketplace facilitator treatment does not automatically extend to your own website.
Mistake #3 — Assuming Marketplace Sales Never Count Toward Nexus
State rules vary.
Mistake #4 — Automatically Canceling Sales Tax Registrations
Existing registrations can carry continuing filing obligations.
Mistake #5 — Reporting Marketplace Tax as Tax You Must Remit
This can create double payment.
Mistake #6 — Ignoring Product Tax Codes
Incorrect product classification can produce incorrect marketplace collection.
Mistake #7 — Ignoring Shipping Taxability
Shipping rules vary by state.
Mistake #8 — Assuming Marketplace Laws Solve Drop Shipping Tax
Supplier-side resale documentation remains a separate problem.
Mistake #9 — Failing to Reconcile Marketplace Reports
Net payouts do not equal gross taxable sales.
Mistake #10 — Assuming the Marketplace Handles Every Tax and Fee
Marketplace facilitator laws may not cover every special tax, fee, or assessment.
Marketplace Seller Compliance Workflow
A multichannel ecommerce seller should build a recurring process.
Step 1 — Identify Every Sales Channel
Examples:
Amazon Etsy eBay Walmart Shopify WooCommerce Wholesale Retail Store
Step 2 — Separate Marketplace and Direct Sales
For every state, track: Marketplace Sales
separately from: Direct Sales
Step 3 — Track Economic Nexus
Apply the actual rules of each state.
Determine whether marketplace sales are included or excluded from the threshold.
Step 4 — Identify Physical Nexus
Review:
Employees
Inventory
Warehouses
Offices
Contractors
Representatives
Property
Step 5 — Determine Registration Requirements
Do not assume marketplace collection automatically eliminates registration.
Step 6 — Configure Product Taxability
Review:
Product codes
Categories
Digital vs. physical
Exempt products
Shipping codes
Step 7 — Maintain Exemption Documentation
Keep applicable:
Resale certificates
Exemption certificates
Marketplace exemption records
Step 8 — Review Marketplace Tax Reports
Verify where the marketplace:
Collected
Remitted
Refunded
Did not collect tax.
Step 9 — Collect Tax on Direct Sales Where Required
Configure direct channels correctly.
Step 10 — Reconcile Every Filing Period
Tie:
Marketplace reports Direct sales Tax returns Accounting records Bank deposits together.
Marketplace Sales Tax Checklist

Review marketplace exemption procedures
Maintain resale certificates
Review drop shipping documentation
Review marketplace tax reports
Reconcile refunds
Reconcile marketplace tax
Reconcile fees
Collect tax on qualifying direct sales
Review use tax on business purchases
Reassess compliance periodically
Final Takeaway
Marketplace Facilitator Laws dramatically simplified one part of ecommerce sales tax:
customer-facing tax collection on marketplace transactions.
But they did not eliminate sales tax compliance for marketplace sellers.
A seller using Amazon, Etsy, eBay, or Walmart still needs to understand:
Where the marketplace collects tax
Whether the seller has physical nexus
Whether marketplace sales count toward economic nexus
Whether direct sales create a registration obligation
Whether the seller still needs to file returns
How marketplace sales should be reported
Whether products are classified correctly
How shipping is taxed
How wholesale purchases and resale certificates are handled
How marketplace reports reconcile to accounting records
The correct compliance model is therefore not:
“Amazon handles sales tax.”
It is:
Marketplace Facilitator Collection + Economic Nexus + Physical Nexus + Direct Sales + Product Taxability + Registration + Filing + Resale Certificates + Use Tax + Reconciliation
For a business selling through multiple channels, all of those pieces need to work together.
