Why do you need to collect sales tax in Indiana?

If you’re selling goods and services in Indiana then sales tax might apply! To determine your obligation, you need to understand “nexus,” which ties businesses to states for tax purposes.

Two types of nexus exist:

  1. Physical Nexus: Having a physical presence, like an office, warehouse, or employees in Indiana, triggers this type. If you do, you likely need to collect sales tax.
  2. Economic Nexus: This kicks in when your sales within Indiana exceed a certain economic threshold. Even without a physical presence, surpassing this threshold requires collecting sales tax.

In Indiana, there is also a transaction threshold of 200, which means that even if your sales aren’t over $100,000 if you’ve sold more than 200 items then you still need to pay sales tax.

Is what you’re selling taxable in Indiana?

Now that you’ve grasped the basics of Indiana’s sales tax and nexus thresholds, let’s delve into whether your specific products or services are taxable.

How to collect sales tax in Indiana

Here’s how to collect sales tax in Indiana:

  1. Calculate the Tax: Determine the appropriate sales tax rate. The base rate in Indiana is 7%, but some localities add additional county or local option income taxes. You can find the specific rate for your area on the Indiana Department of Revenue (DOR) website or by using a sales tax calculator.
  2. Charge the Tax:  Unless you have a valid exemption certificate from the buyer, you must add the sales tax to the sales price of taxable goods and services. Most point-of-sale systems can automatically calculate and add the tax.
  3. Keep Records: Maintain accurate records of your sales and the amount of sales tax collected for each transaction. This includes the date, customer information, itemized sales, and the total tax collected.
  4. File and Pay Sales Tax:  The Indiana DOR will assign you a filing frequency (monthly, quarterly, or annually) based on your sales volume. You must file your sales tax return and submit the collected tax by the due date.
  • You buy a shirt for $20 in Indiana (7% base rate). 
  • The total tax is $20 x 7% = $1.40 (rounded). 
  • Including tax, you pay $20 + $1.40 = $21.40.


Do you have a physical nexus in Indiana?

  • Having employees or independent sales representatives in Indiana: Even if they don’t work full-time, regular visits by salespeople can create nexus.
  • Storing inventory in Indiana: This applies even if you use a fulfillment service like Amazon FBA.

  • Earlier filers (high volume): Businesses that averaged more than $1,000 per month in sales tax liability during the previous calendar year must file and pay by the 20th of the following month.
  • Standard monthly filers (lower volume): Businesses averaging less than $1,000 per month in sales tax liability typically file by the end of the month following the reporting period (30th day).

If the due date falls on a weekend or holiday, the sales tax is due on the next business day.
