Iowa Department of Revenue outlines sales-tax rules for remote sellers and marketplace facilitators

Iowa SourceLink and the Iowa Department of Revenue held a webinar explaining when out-of-state sellers and marketplace facilitators must collect and remit Iowa sales and use tax, including details on the $100,000 economic‑nexus threshold, marketplace‑facilitator responsibilities, permitting and filing through GovConnectIowa, and common exemptions and special‑event rules.

Department presenters advised that retailers must collect sales tax when a sale is sourced to Iowa — for example when the purchaser first takes possession in Iowa, delivery occurs in Iowa, or a taxable service is first used in Iowa. “Please be advised that the information in this presentation contains informal opinions and are only applicable to the factual situations referenced into the statutes in existence as of the date of this presentation,” said Terry O'Neil, revenue service specialist, reading the department’s disclaimer.

Why it matters: the obligation to collect and remit can fall on an out‑of‑state remote seller that lacks any physical presence in Iowa if that seller (or a marketplace facilitator selling on its behalf) has $100,000 or more in gross revenue from Iowa sales in the current or prior calendar year. Nick Belke, policy director at the Iowa Department of Revenue, summarized the threshold: “remote sellers and marketplace facilitators must collect Iowa sales tax if they have $100,000 or more in gross revenue from Iowa sales in a current or prior calendar year.”

Economic nexus and physical nexus. Department staff drew a clear distinction: physical presence (a store, inventory, employees or a temporary booth in Iowa) creates nexus regardless of revenue, and then the seller must collect tax. Economic nexus applies when a remote seller without physical presence has $100,000+ in gross revenue from Iowa sales (the department counts gross receipts from taxable and exempt sales, and sales for resale). Belke gave a timing example: if a seller first exceeds the threshold on Sept. 15, it must begin collecting on Nov. 1 and continue through at least Dec. 31 of the following year.

Marketplace facilitators. The department explained that a facilitator that provides marketplace infrastructure and collects payments can be the party responsible for collecting and remitting Iowa sales and applicable local option sales tax; in that case, individual marketplace sellers who sell only through that facilitator do not need a separate Iowa sales tax permit or to file returns for those marketplace sales. However, marketplace sellers must confirm with their facilitator whether the facilitator will collect Iowa tax, and sellers who make both marketplace and non‑marketplace sales must aggregate all gross sales when testing the $100,000 threshold.

Permits and filing. Businesses with nexus in Iowa must register for a sales and use tax permit via GovConnectIowa (govconnect.iowa.gov). Matt Bishop, Department of Revenue staff, said permit registration and electronic filing through GovConnectIowa are required; paper returns are not accepted for sales tax filings beginning July 1 (per recent legislative change). Filing frequency is typically monthly for retailers who collect at least $1,200 in sales tax annually; annual and seasonal filing options are available under specified conditions.

Local option and use tax. The statewide sales and use tax rate is 6 percent; many jurisdictions also impose a local option sales tax of up to 1 percent. Local option sales tax does not apply to use tax; use tax (generally 6 percent) complements sales tax when tax was not collected at the time of sale and is typically remitted by the purchaser.

Common exemptions and special cases. Presenters noted common exemptions — food for human consumption, prescription drugs and qualifying medical devices, resale purchases, qualifying manufacturing machinery and equipment — and directed sellers to department publications for full lists. Delivery charges are exempt when the seller separately states transportation charges on the invoice and the seller performed the delivery. Special‑event sponsors can be treated as marketplace facilitators if they both provide marketplace infrastructure/support and collect the sales price; if a special‑event sponsor is not a facilitator, individual retailers must obtain Iowa permits and collect sales tax (the department does not issue temporary permits for events).

Audience Q&A highlights. In response to questions, staff said: if an Iowa vendor performs equipment repair in Iowa and charges tax, the purchaser pays sales tax; if the vendor fails to charge sales tax, the purchaser may owe use tax (6 percent) and the department asked to be notified of sellers who are not charging required tax. On delivery fees, Terry O'Neil said the fee is exempt when separately itemized and the seller provides the delivery. The department also noted a 5 percent excise tax that can apply to certain self‑propelled construction equipment, while qualifying manufacturing machinery remains exempt.

Where to get help. Presenters repeatedly urged sellers with specific fact patterns to contact the Iowa Department of Revenue for tailored guidance and pointed attendees to revenue.iowa.gov and the department’s remote‑seller guide. The webinar recording and slides will be posted by Iowa SourceLink, and the department listed email and phone contacts for follow‑up. The presenters announced a related Department of Revenue webinar scheduled for Aug. 13 to cover law changes from the 2025 legislative session.

The session closed after a question‑and‑answer period; attendees were reminded the department’s spoken guidance is informal and that binding relief requires formal procedures set out in Iowa administrative rules.
