What constitutes sales tax nexus in Iowa?
One of the more complicated aspects of Iowa sales tax law is sales tax nexus, the determination of whether a particular sale took place within the taxation jurisdiction of Iowa, and is thus subject to state (and possibly local) sales taxes.
If a vendor's transactions are determined to have nexus in Iowa, the vendor must register for a Iowa sales tax license and collect appropriate sales taxes from the buyer for all transactions with nexus in the state. On this page, we have compiled some of the most commonly needed facts about what constitutes sales tax nexus in Iowa.
