Iowa Marketplace Facilitator Sales Tax Rules — 2026

Updated 2026-04-27

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

Economic nexus in Iowa triggers at $100,000 in gross sales delivered into Iowa in the current or prior calendar year. No transaction count threshold.
