Etsy and eBay Sales Tax: Where the Platform Stops

What the Platform Actually Covers

Facilitator laws made platforms responsible for the tax on transactions they process. For a seller who operates only on Etsy or eBay and holds no inventory elsewhere, that genuinely does resolve most of the collection question in most states.

The trouble starts the moment anything happens off-platform — and for most growing sellers, something always does. The mechanics are set out in marketplace facilitator laws.²

Thresholds Still Move

A seller can reasonably conclude that because the platform collects, thresholds are irrelevant. In several states they are not: the threshold measures sales into the state, and marketplace orders count toward it even though the platform handled the tax.

The 1099-K Reconciliation

Platforms report gross payment volume to the IRS and, in several cases, to states. That figure will not match your sales tax returns, and it is not supposed to.¹

A 1099-K includes shipping charges, sales tax collected, and sales later refunded. A return reports taxable sales. The difference is legitimate — but a state comparing the two sees a gap, and the only thing that makes the gap safe is being able to explain it on demand. That reconciliation is the most common audit trigger, covered in what triggers a sales tax audit.

In-Person Selling Is Physical Presence

A weekend market in another state is a physical presence in that state for the period you are there, and many states require a temporary permit for event sellers. It is a small obligation that is easy to miss and easy to comply with — and one that also creates a record of your presence.

What the Marketplace Does Not Cover

Marketplace facilitator laws made platforms responsible for collecting on the sales they facilitate — which solved most of the problem and left a specific, commonly missed remainder:

• Your own storefront. Sales through your own website, social DMs, invoices, or a personal Shopify are not marketplace sales. The platform collects nothing on them and you are responsible wherever you have nexus.
• Threshold measurement. In many states marketplace sales still count toward your own economic nexus threshold even though the platform collected on them. A seller doing $95,000 on Etsy and $20,000 direct can be over a $100,000 threshold and owe collection on the direct sales — platform volume triggered the obligation without covering it.
• Craft fairs and in-person events. Selling in person is physical presence, which creates nexus immediately and without any threshold — often in a state where you previously had none.
• Your own purchases. Supplies and equipment bought without tax charged create a use tax liability no platform handles.

Reading Your Platform Reports

Both Etsy and eBay publish reports showing tax collected and remitted on your behalf. Two habits make them useful rather than decorative:

• Reconcile gross to net every month. Your deposit is sales minus fees minus tax remitted. Booking the deposit as revenue overstates income and hides the tax line entirely — the most common bookkeeping error for platform sellers.
• Keep the reports for the audit window. When a state asks why you reported no tax on $80,000 of sales into it, the marketplace settlement report is the answer. Without it, the assessment stands.

The Five-Step Method

1. Separate marketplace sales from direct sales. Split your revenue by channel. Only marketplace orders are covered by the platform's collection.
2. Check how each state counts marketplace sales. Establish whether the states you sell into include facilitator sales in the threshold measure, because that changes whether you have crossed.
3. Register where you have nexus. Physical presence, including inventory and in-person selling, and crossed thresholds both create obligations the platform does not discharge.
4. Collect on every channel the platform does not cover. Switch on collection for your own site, and charge correctly at fairs and markets in states where you are registered.
5. Reconcile your 1099-K before a state does. Explain the gap between gross payment volume and taxable sales in your own records, so an enquiry is answered rather than investigated.
