Marketplace facilitator laws require platforms (Amazon, eBay, Etsy, TikTok Shop, etc.) to collect and remit sales tax on behalf of sellers in states where they meet marketplace facilitator thresholds. This means: (1) if you ONLY sell through marketplaces, you may not need to register for sales tax separately, (2) but you still need to file zero returns or exempt seller registrations, (3) direct sales (your own website) still require your own registration. 46 states + DC have marketplace facilitator laws.

Common Mistakes

Assuming marketplace facilitator laws cover ALL your sales in a state

💥 Consequence: Missing tax on direct/website sales that aren't through the marketplace

Fix: Separate marketplace sales from D2C sales — facilitator laws only cover marketplace transactions

Not filing returns in states where Amazon collects — many states still require it

💥 Consequence: Administrative penalties for non-filing even when tax was collected

Fix: File zero-dollar returns in states where only platforms collect
