The frequency with which a business must file is determined by its tax liability. Indiana uses a graduated system based on the amount of sales tax collected in the previous year. Annual filers are those whose total tax liability is $1,000 or less per year; they file once a year. Quarterly filers have a liability between $1,001 and $12,000 per year, filing four returns. Monthly filers, for whom liability exceeds $12,000 per year, are the most common for established retail businesses. The highest volume sellers—typically those collecting more than $60,000 per month—may be required to file semi-monthly or even accelerated (quarterly prepayments). It is crucial for a new business to accurately estimate its sales volume; the DOR will assign a filing frequency, but it can be adjusted as revenue patterns become clear.
With registration complete, the core of the process—filing the return—begins. Indiana’s sales tax is a tax on the retail sale of tangible personal property and certain specified services. The tax is imposed on the consumer, but the business acts as an agent of the state, collecting it at the point of sale. The current state sales tax rate in Indiana is a flat 7%, which is among the higher rates in the Great Lakes region. Importantly, Indiana is a “destination-based” sourcing state for sales tax, meaning the rate applied is based on the location where the buyer takes possession of the item. While the state rate is uniform, local county taxes are also collected through the state system, but the combined rate is always calculated using the destination address. The business’s responsibility is to accurately collect this 7% (plus any applicable local tax on certain transactions like innkeeper’s taxes) and then report the total taxable sales and tax collected on the prescribed state form, Form ST-103 (Sales and Use Tax Return).
If you have non-taxable sales (such as sales for resale, sales to exempt organizations, or manufacturing equipment), you will enter these in the deductions section. Ensure you have valid exemption certificates on file to back these up in case of an audit. file indiana sales tax

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.
Missing a deadline or filing incorrectly can lead to penalties that eat into your profits. Fortunately, Indiana has a relatively streamlined system once you understand the basics.
