Indiana Sales and Use Tax: Rates, Nexus, Exemptions, and Filing Requirements for Businesses

Indiana has a statewide sales and use tax rate of 7% with no local sales taxes.
Sales tax applies to tangible personal property and certain services; exemptions include most services, food, agricultural items, medical equipment, and SaaS.
Nexus for sales tax collection can be established by physical presence or by exceeding $100,000 in Indiana sales (economic nexus).
Exemptions are available for certain entities (e.g., nonprofits, schools, government) with proper documentation (Form ST-105).
All sellers must file and remit sales tax electronically; Indiana participates in the Streamlined Sales Tax (SST) initiative and does not have sales tax holidays.
