Do you need to collect sales tax in Indiana?

You have a duty to collect once you have nexus: physical presence (inventory, staff, an office) or economic nexus from crossing $100,000 in sales over current or preceding calendar year. Indiana used to trigger nexus at 200 transactions but removed that count in January 2024 — only the sales figure matters now.

The Indiana rate

Indiana has a single statewide sales tax rate of 7%. There are no local or district sales tax add-ons; the 7% rate applies uniformly across all cities and counties statewide.

Marketplace and direct sales

Marketplaces like Amazon collect Indiana tax for you, but those sales don't count toward your own threshold. Direct sales on your own store you collect yourself.

Filing and zero returns

Once registered, Indiana requires a return every assigned period even when you owe $0 — miss one and you can face penalties. Filing frequency is assigned by the Indiana DOR based on average monthly sales tax liability: monthly filers have average monthly liability exceeding $1,000; quarterly filers have average monthly liability between $200 and $1,000; annual filers have average monthly liability below $200.

When you can cancel

If your Indiana returns are mostly $0, you may be over-registered. Canceling your Indiana sales tax registration makes sense once you have confirmed that your gross sales into Indiana did not exceed $100,000 in both the current and the preceding calendar year, meaning you can wait until you have completed the full following calendar year below threshold. The key catch is that Indiana requires you to file and remit a final sales tax return covering all activity through your permit's closing date before the cancellation is complete — if you skip this step, the Indiana DOR may continue issuing estimated tax bills.
