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.

The actual filing process in Indiana is heavily streamlined through electronic means. The Indiana DOR strongly encourages—and for most filers, requires—electronic filing and payment. The primary portal is the DOR’s e-services center, accessible through the INBiz website or directly via the DOR’s INTIME (Indiana Tax Information Management Engine) system. To file, the business will need its RRMC number, the filing period, and its sales data, including gross retail sales, taxable sales, exempt sales (e.g., sales for resale, groceries, certain medical items), and the total tax collected. Deductions for bad debts or returns can also be claimed. Once the return is completed online, payment is due. Electronic payments can be made via ACH debit (allowing the DOR to pull funds from a bank account), ACH credit, or credit card (though fees may apply). Paper returns are generally reserved for annual filers with minimal liability. The first step in filing Indiana sales tax
