What is Marketplace facilitator tax?

What a marketplace facilitator actually does

A marketplace facilitator is a platform that connects third-party sellers with buyers and processes the resulting transactions. Once a state's marketplace facilitator law applies, the platform — not the seller — is responsible for collecting and remitting the sales tax on sales it facilitates in that state. This shifted the compliance burden away from the thousands of small sellers on a platform and onto the platform itself, which the states preferred because it is far easier to collect from one Amazon than from a million sellers.

The key word is facilitated. The law covers sales that happen through the marketplace. It generally does not cover sales you make through other channels you operate yourself, such as your own Shopify store, where you may still be the party responsible for collection depending on your nexus. Whether a platform is treated as a facilitator can also vary — for example, sellers often ask whether Shopify is a marketplace facilitator, and the short answer is that Shopify is typically a payment and storefront tool rather than a facilitator, which puts the collection responsibility back on you for those sales.

• •The marketplace calculates the correct sales tax at checkout
• •It collects the tax from the buyer as part of the order
• •It remits the tax directly to the state
• •It applies to sales facilitated through that platform, in states with facilitator laws
• •It generally does not cover sales through channels you run yourself

How marketplace facilitator tax flows through your accounting

Even though Amazon handles the remittance, the tax still moves through your transaction data. On your settlement report you will see the tax Amazon collected and the corresponding amount it withheld to remit. The correct accounting treatment is to record that this money is not your revenue — it is tax that passed through you to the state — so it should net out rather than inflate your sales or sit as a phantom liability.

If you book the tax Amazon collected as income, you overstate revenue and distort margin. If you record the collection but not the remittance, you create a sales-tax-payable balance that never clears. The clean approach is to recognize that marketplace-facilitated tax is a wash on your books — collected and remitted by the platform — and to use a clearing or pass-through treatment so it reconciles to zero. This is one of the most common reconciliation messes in ecommerce bookkeeping.

What the marketplace does NOT handle for you

Marketplace facilitator laws cover marketplace sales. They do not automatically resolve your obligations on direct sales through your own website, and they do not eliminate the question of where you have nexus. If you have sales-tax nexus in a state from inventory stored there or from your own direct sales volume, you may still owe registration and filing duties for the non-marketplace portion of your business.

Some states also still expect sellers to register and file informational or zero returns even when the marketplace remits the tax, and rules differ state by state. Because the details vary and change, treat marketplace facilitator coverage as handling one slice of your obligations — the marketplace slice — and verify the rest against each state's current requirements or with a tax professional rather than assuming you are fully covered.

Frequently asked questions

What is marketplace facilitator tax?

It is sales tax that a marketplace like Amazon, eBay, or Etsy collects from the buyer and remits to the state on your behalf, under marketplace facilitator laws in effect across most US states. The platform is treated as the responsible party for tax on sales it facilitates, which removes much of the collection burden from individual sellers. It applies only to sales made through that marketplace.

Do I still owe sales tax if Amazon collects it for me?

For sales facilitated through Amazon in facilitator states, Amazon collects and remits the tax, so you generally don't remit it again on those sales. However, you may still owe tax on sales through your own channels, and some states still require you to register or file returns even when the marketplace remits. Rules vary by state, so verify your specific obligations.

Is Shopify a marketplace facilitator?

Generally no. Shopify is typically treated as a storefront and payments platform rather than a marketplace facilitator, which means it does not remit sales tax on your behalf. For Shopify sales, the responsibility to collect and remit usually falls on you based on where you have nexus. Confirm current treatment, since classifications can differ by state.

How do I record marketplace-collected sales tax in my books?

Treat it as a pass-through, not as revenue. The tax Amazon collected and remitted should net to zero on your books — recording it as income overstates your sales, and recording only the collection creates a sales-tax-payable balance that never clears. A clearing-account or wash treatment that reconciles to zero is the clean approach.

Does marketplace facilitator tax cover my Shopify or wholesale sales?

No. It only covers sales facilitated through the marketplace. Direct sales through your own website or wholesale channels are outside its scope, and you remain responsible for those based on your nexus footprint. Treat marketplace coverage as one slice of your obligations and handle the rest separately.
