Important note: Zero returns
Once you have an Indiana Registered Retail Merchant Certificate, you are required to file returns for every assigned period regardless of whether any sales tax was collected. When no sales tax was collected, you must file a zero return electronically through INTIME.
How to prepare your Indiana sales tax return
Before working on your sales tax return, collect all sales information for the tax period.
Sales transactions
You need to know your total gross sales to Indiana buyers and your taxable sales. Indiana taxes digital goods and SaaS (Software as a Service), so those transactions should be included in your taxable sales figures.
Key reporting figures
In addition to your gross Indiana sales, filing a return requires:
- Total sales and income
- Taxable sales
- Non-taxable sales and exemptions
- Deductions and adjustments
- Total sales tax collected from customers during the filing period
Indiana has no local taxes, so you report a single statewide figure, there is no need to break down sales by county or city.

Indiana sales tax returns are filed electronically through INTIME and must be reported in US dollars.

Late filing penalties and interest
If you miss an Indiana sales tax filing deadline, file as soon as possible. Failure to file returns and remit collected tax on time results in penalties and interest charges that increase the longer you wait.
