For businesses operating in Indiana, the obligation to collect and remit sales tax is not merely a clerical formality but a fundamental legal and financial responsibility. Indiana, like most states, relies heavily on sales tax revenue to fund essential public services, including education, infrastructure, and public safety. Consequently, the state’s Department of Revenue (DOR) has established a structured, detailed process for filing sales tax returns. Understanding this process—from registration and determining nexus to filing frequencies, methods, and compliance deadlines—is critical for any business to avoid penalties and maintain good standing within the Hoosier State.

The first step in filing Indiana sales tax is establishing the legal requirement to do so, which hinges on the concept of “sales tax nexus.” Nexus refers to a sufficient physical or economic connection with the state. Historically, a physical presence, such as an office, warehouse, employees, or inventory stored in Indiana, triggered nexus. However, following the landmark U.S. Supreme Court case South Dakota v. Wayfair, Inc. (2018), Indiana—like many states—enacted economic nexus laws. As of today, any out-of-state seller that generates more than $100,000 in gross revenue from sales into Indiana or engages in 200 or more separate transactions with Indiana customers in the current or previous calendar year must register, collect, and remit sales tax. Once nexus is established, the business must register for a Registered Retail Merchant Certificate (RRMC) with the Indiana DOR, often via the online portal INBiz.
