Iowa SourceLink webinar: Iowa Department of Revenue outlines sales and use tax basics for businesses

Iowa Department of Revenue policy officials gave businesses a concise primer on sales and use tax during an IASource Link webinar, stressing how the tax applies and when sellers must collect and remit.

"Sales tax is imposed on the sales price of tangible personal property, specified digital products and taxable services," said Matt Bishop, policy director for sales and excise taxes at the Iowa Department of Revenue. He emphasized that "sales price" is the total consideration for a sale and must be calculated even when noncash payment or barter is used.

Bishop explained that specified digital products (downloads, movies, games) are always taxable and that enumerated services are taxable only when described as such in law. He used electricity as an example of tangible property that may not be physically touchable but is taxable when perceptible by a sense.

The panel outlined sourcing: sales are sourced to the purchaser’s receipt location (for example, the retail location where a customer picks up an item or the customer’s delivery address). Sales tax is owed when a sale is sourced to Iowa and the retailer has nexus. "If the retailer has nexus with Iowa, that retailer is responsible for collecting, reporting, and remitting that sales tax to the state of Iowa," Bishop said.

Nexus can be physical (a brick‑and‑mortar location, temporary presence, or other business property in Iowa) or economic. Under current guidance discussed in the webinar, economic nexus is triggered when a seller makes $100,000 or more in gross revenue from Iowa sales in a 12‑month period. Panelists noted that marketplace facilitators that meet the sales threshold also have collection obligations.

Panelists described local option sales tax (LOST) rules: retailers required to collect state sales tax must also collect applicable LOST in jurisdictions that impose it, and items exempt from state sales tax are typically exempt from LOST. The statewide sales tax rate discussed in the session is 6%; many Iowa localities also levy a 1% LOST in addition to state tax.

Use tax is complementary to sales tax and generally becomes due when sales tax should have been collected but was not, or when certain items are exempt from sales tax but are explicitly subject to use tax (an example cited was aircraft). The panel encouraged businesses to consult Iowa law and the department website for full lists and edge cases.

Why it matters: getting nexus, sourcing, and taxable classification wrong can trigger assessments, penalties and interest. The department recommended that businesses review the Iowa Code and administrative rules cited during the webinar and consult department resources for binding guidance if needed.

The department will post the recorded webinar and slides; attendees were directed to department resources and the IASource Link site for further details and statutory citations.
