Do I need to register for sales tax in both Iowa and Nebraska?

It depends on where you cross each state's economic nexus threshold (or have physical presence there). Iowa's published threshold is $100,000, and Nebraska's is $100,000 or 200 transactions. You generally register in a state only once you cross its threshold, so you may have an obligation in one, both, or neither.

Iowa's economic nexus rule took effect on 2019-07-01, and Nebraska's took effect on 2019-04-01. Both stem from the 2018 South Dakota v. Wayfair Supreme Court decision, which let states require remote sellers to collect once an economic threshold is met.

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 Iowa originally enacted a $100,000-or-200-transaction test effective January 1, 2019 (Senate File 2417) but eliminated the 200-transaction threshold effective July 1, 2019 (House File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. Iowa Department of Revenue source data last retrieved 2026-06-14.

Nebraska — nexus note

Economic nexus in Nebraska triggers when remote sellers exceed $100,000 in gross sales OR 200 or more separate transactions into Nebraska in the current or preceding calendar year — whichever is met first.
