Use this Iowa marketplace facilitator sales tax guide to check 2026 rules, collection requirements, effective-date notes, threshold counting, and how Amazon, Etsy, eBay, DoorDash, and Uber Eats orders differ from direct-store sales. Direct channels still use the $100,000 threshold.

Iowa's marketplace facilitator law

Iowa has a marketplace facilitator law: marketplaces (Amazon, Etsy, eBay, Walmart Marketplace) calculate, collect, and remit sales tax on your behalf for transactions they facilitate to Iowa buyers.

This significantly reduces your compliance burden if you sell primarily through marketplaces. But it does not exempt you from registering if you also have direct channels (your own store, wholesale, trade shows, etc.).

Key distinctions

  • Facilitated sales (collected by the marketplace): you generally don't collect or remit.
  • Direct sales (your own checkout): your responsibility as before.
  • Informational filings may still be required depending on Iowa's rules, even on marketplace-facilitated volume.
  • Most states exclude marketplace-facilitated sales from your economic nexus threshold calculation, but double-check Iowa specifically before assuming.

Marketplace-specific gotchas in Iowa

  • Not every platform you sell on is legally a marketplace facilitator. Shopify's store platform is not — you are the seller of record. Shopify's Markets Pro is. Verify per platform.
  • Wholesale sales through a marketplace are usually NOT marketplace-facilitated — the marketplace is a payment conduit, not the seller. Direct-collect obligations still apply.
  • Returning customers and refunds: if the marketplace remitted tax and you process a refund outside the marketplace, the refund usually needs to flow through the marketplace to trigger the tax reversal. Off-marketplace refunds create reconciliation headaches.

Iowa nexus note

Iowa sales/use tax nexus and economic nexus threshold: a remote seller or marketplace facilitator must register, collect, and remit Iowa sales tax only if its gross revenue from Iowa sales is $100,000 or more in a calendar year. Iowa originally enacted a $100,000-or-200-transaction test effective January 1, 2019 (Senate File 2417) but eliminated the 200-transaction threshold effective July 1, 2019 (House File 779), so the current trigger is sales-only. The $100,000 figure counts all Iowa revenue, including exempt sales, wholesale sales, sales for resale, and sales for which a marketplace facilitator collected the tax. Marketplace facilitators meeting the threshold collect and remit on behalf of their marketplace sellers. Iowa imposes a 6% state sales tax plus a 1% local option sales tax in most jurisdictions.

Do marketplace sales count toward my Iowa nexus threshold?
In most states, marketplace-facilitated sales are EXCLUDED from the economic nexus threshold calculation. But Iowa may differ — verify before assuming.
Does Shopify qualify as a marketplace facilitator?
Standard Shopify (your own standalone store) does NOT qualify — you're the seller of record. Shopify Markets Pro, however, does qualify as a marketplace facilitator in many states.
