Amazon and eBay Sales Tax Rules for Online Sellers

Amazon and eBay sales tax questions usually begin with a simple concern: if the marketplace charges tax to the buyer, does the seller still have anything to do? The answer depends on the state, the sales channel, the seller’s physical presence, the marketplace’s collection status and the seller’s direct sales.

Many states require marketplace facilitators to collect and remit tax on sales made through their platforms. That can remove one checkout task for a marketplace seller, but it does not always remove registration, income or business-tax reporting, recordkeeping or direct-website obligations.

Washington says a marketplace seller may need to register when combined gross receipts sourced or attributed to Washington exceed its threshold. It includes sales through a facilitator, a seller’s own website and other channels in that threshold review.[1] Colorado says a marketplace seller generally does not collect state sales tax on products sold through a marketplace facilitator, but a multichannel seller must collect on its own website or store sales.[2]

This guide explains the workflow without treating Amazon or eBay as a substitute for state law. It is general information, not a personalized compliance decision.

Who Usually Collects Sales Tax on Amazon and eBay?

A marketplace facilitator is a business that provides a physical or electronic marketplace where third-party sellers offer products or services. Depending on state law, the facilitator may list products, process payments, provide customer service or fulfillment, and collect and remit sales tax.

When a facilitator is required to collect, the buyer may see sales tax charged at checkout even though the seller does not manually add the tax. The marketplace then reports and remits the collected amount under its state process.

Facilitated sale

A facilitated sale is made through the marketplace’s platform. The seller supplies the product or service, while the platform handles part of the transaction. The state may make the facilitator responsible for the sales-tax collection.

Direct sale

A direct sale is made through the seller’s own website, store, catalog or another channel outside the facilitator’s collection system. The seller must review its own registration and collection obligations for that channel.

Collection certificate or report

Some states or marketplaces provide a certificate, monthly report or other documentation showing that tax was collected. Keep that document with the order and tax records. Massachusetts says a marketplace seller can generally rely on a marketplace facilitator collection certificate for facilitated sales when the required conditions are met.[3]

Collection does not mean tax-free

The customer may still pay sales tax on the order. “The marketplace collected it” means responsibility for collection and remittance may sit with the facilitator. It does not mean the underlying sale should be omitted from every business record.

Marketplace-Facilitated Sales Versus Direct Sales

A seller should keep a separate channel view even when the marketplace collects tax.

Colorado calls a seller that sells through a marketplace and its own website or store a multichannel seller. It says the seller must collect and remit state sales tax on its own shop or website sales, while marketplace-facilitated sales are handled by the marketplace under the state’s rules.[2]

Why a seller’s own website changes the review

A marketplace’s collection responsibility does not automatically cover sales on an independent website. Track website orders by destination and compare the total with the state’s remote-seller threshold.

What if the seller uses more than one marketplace?

Add Amazon, eBay and other channel data in the way the state’s threshold rule requires. Do not assume that each platform is measured separately. Washington says its threshold calculation can include sales through a facilitator, the seller’s own website and other channels.[1]

What if the marketplace does not collect?

If the facilitator is not required to collect, the seller may have to review its own duty. Check the state guidance, marketplace contract, buyer location, product taxability and registration threshold.

When an Online Seller May Still Need to Register

A seller can have a filing or registration obligation even when a marketplace collects tax on facilitated orders.

Physical presence

Inventory, employees, offices, stores, representatives or other activities can create physical nexus. The cited marketplace guidance says a seller with physical presence is generally required to register in the state regardless of sales amount, subject to the state’s law and exceptions.[4]

Economic nexus

A state can require an out-of-state seller to register after its sales into the state reach a threshold. The amount, measurement period, included sales and collection date vary.

Direct website sales

If the seller crosses a threshold through direct website sales, it may need to register and collect even though a marketplace handles a different set of orders.

Business or gross-receipts taxes

A state can impose business, occupation, income or other reporting duties separate from sales tax. Washington says a marketplace seller may still need to report B&O tax even when the facilitator collects retail sales tax.[1]

Proof that the facilitator collected

If a seller relies on marketplace collection, keep proof. Washington says a seller that makes all retail sales through a facilitator may not need to collect and submit retail sales tax if it has proof that the facilitator is doing so, but other tax duties can remain.[1]

Massachusetts example

Massachusetts says remote sellers must collect when Massachusetts sales exceed $100,000 in a calendar year. Its guidance also explains facilitator collection and seller certificates.[3] The state’s rules are an example of why a seller should read the specific state page instead of applying one national assumption.

How to Check Marketplace Tax Reports

A monthly reconciliation can catch missing orders, refunds and direct-channel exposure.

1. Export gross orders from Amazon, eBay and other marketplaces.
2. Separate facilitated orders from direct website and store orders.
3. Group each order by destination state and transaction date.
4. Compare marketplace tax charged with the marketplace’s remittance report.
5. Record refunds, cancellations, exempt sales and chargebacks.
6. Add direct sales to the state-threshold worksheet.
7. Save collection certificates, rate reports and state notices.
8. Send exceptions to the reviewer before filing a return.

What to do with facilitated sales on a return

Return treatment varies. Some states want gross sales reported with a deduction for facilitator-collected sales. Others may use a different field or require no seller return when all conditions are met. Follow the state return instructions and keep the platform report.

Do not rely on one payout amount

A marketplace payout can be reduced by fees, refunds, advertising, shipping or reserves. It is not automatically the same as gross sales or taxable sales. Compare order-level data with the payout and tax report.

State Examples and Important Exceptions

Washington

Washington says marketplace sellers may need to register when combined gross receipts sourced or attributed to Washington exceed $100,000 or another condition applies. It says the threshold includes retail sales through a facilitator, the seller’s own website and other channels, and that physical presence can require registration below the threshold.[1]

If all sales are through a facilitator, Washington says the seller may not need to collect and submit retail sales tax if it has proof the facilitator is doing so. The seller can still have B&O and other reporting duties.[1]

Colorado

Colorado says marketplace sellers no longer need to collect and remit state sales tax on products sold through a marketplace facilitator under its stated rules. It distinguishes direct website or store sales for a multichannel seller.[2]

Massachusetts

Massachusetts uses a $100,000 calendar-year threshold for remote sellers and marketplaces in its guidance. It explains that marketplace facilitators collect tax for facilitated sales and that a marketplace seller may rely on a collection certificate for those sales when the conditions are satisfied.[3]

General multistate caution

The cited marketplace guidance says state laws control and that a marketplace seller may also be a remote seller. A seller that makes both marketplace and direct sales must review the state threshold and registration process.[4]

These examples are not a complete 50-state rulebook. They show why the seller’s spreadsheet needs one row per state, one source URL and one review date.

Common Questions About Amazon and eBay Sales Tax

Does Amazon always collect sales tax for sellers?

No universal answer applies to every state, product or transaction. Marketplace laws often require collection, but state definitions, thresholds and seller duties vary.

Does eBay sales tax work the same way as Amazon sales tax?

Both platforms can operate as marketplace facilitators in transactions where state law requires collection, but the seller should verify platform reports and state-specific rules. Do not assume identical reporting or certificate formats.

Do I need a sales-tax permit if Amazon collects tax?

Maybe. Physical presence, direct sales, business taxes, marketplace documentation and state thresholds can still create a registration duty.

Do marketplace sales count toward economic nexus?

They can. Washington says marketplace and other channel sales can be included in its threshold review.[1] Other states must be checked individually.

Do I collect sales tax on my own website?

If your business has nexus or another legal duty in the destination state, you may need to register and collect. The marketplace’s collection does not cover your independent website automatically.

Should marketplace tax be included in my records?

Keep the gross order, tax amount, refund, facilitator report and payout reconciliation. A marketplace collection report supports the seller’s review.

What if I sell only through Amazon or eBay?

A seller with no physical presence may have fewer sales-tax collection tasks when the facilitator is responsible, but state registration, business-tax, threshold and recordkeeping rules can remain.

What if I sell at a local craft fair too?

A physical event can create a separate permit or collection obligation. Check the state and local event rules.

How do I calculate sales tax for a direct order?

Identify the taxable item, destination, current rate and any exemption. Then calculate the tax on the taxable price. Use the state’s rate lookup and keep the source.

Can a sales-tax calculator tell me whether I must register?

No. A calculator can estimate tax after the correct rate and taxable base are known. Registration requires a nexus and state-law review.

The safest Amazon and eBay sales-tax workflow is to separate marketplace and direct orders, preserve the platform’s collection reports, monitor each state’s threshold, review physical presence and document every decision. A marketplace may collect tax for a facilitated sale, but the seller remains responsible for understanding its full business picture.
