Marketplace Facilitator Tax Calculator
Who collects, and what still counts toward nexus.
Rates change with budgets and local ballot measures, and the rate that applies depends on the delivery address and product category. Treat these as planning figures, not as a filing.
Nexus position
Registration required
$158,000 counted against $100,000
The marketplace collects on $140,000 of sales, but those sales still push you over the threshold — so you register and file for $1,485 of tax on direct sales alone. That mismatch is the single most common surprise in US ecommerce tax.
How the Marketplace Facilitator Tax Calculator works
Marketplace facilitator laws moved the collection duty to the platform, so Amazon, Etsy and eBay now collect and remit the tax on their sales. The trap is that many states still count those sales toward your nexus threshold — so you register, and file, for tax on a small slice of direct sales.
Not financial advice. Marketplace fees change, and they vary by country, plan and seller status. Every rate here is an editable default, not a quoted price — check the platform's current fee schedule before you price a product against it. This is not tax or business advice.
Frequently asked questions
Do I still owe tax on marketplace sales?
Generally no — the platform collects and remits it. But you may still need to report those sales as exempt on your own return in states where you are registered, which is why the paperwork does not disappear.
Do marketplace sales count toward nexus?
In many states, yes. That is the mismatch that catches sellers: platform sales create the registration obligation, then the platform handles the tax on them, leaving you filing returns for a fraction of your volume.
What if I sell on a marketplace and my own site?
You collect and remit on your own site's sales in every state where you have nexus. The marketplace handles its own. Two channels, two different responsibilities, one return.
Which platforms are facilitators?
Amazon, eBay, Etsy, Walmart and Shopify's marketplace surfaces all act as facilitators. Shopify running your own store does not — that is your store, so collection is your responsibility.
