Indiana Tax Nexus

Businesses with nexus in Indiana are required to register with the Indiana Department of Revenue and to charge, collect, and remit the appropriate tax.

Generally, a business has nexus in Indiana when it has a physical presence there,  such as a retail store, warehouse, inventory, or the regular presence of traveling salespeople or representatives. However, out-of-state sellers can also establish nexus in the ways described below.
