How-To Guides: Indiana SaaS VAT

Step: 1 Determine if you need to register.

You must collect sales tax in Indiana if you have nexus in the state. There are two types of nexus that impact sales tax filing obligations.

  • Physical nexus means that a business (or seller) has a tangible presence or activity in a state, and this presence requires them to pay sales tax in that state.
  • Economic nexus means that a business or seller meets a state’s economic threshold for total revenue or the number of transactions in that state.

Remote seller economic nexus threshold is USD $100,000 in gross sales into Indiana in the current or previous calendar year. Registration becomes mandatory once the threshold is met. 

Step: 2 Business Registration

Register with the Indiana Department of Revenue (IDOR) through the Indiana Taxpayer Information Management Engine (INTIME) portal. The process requires creating an INTIME account, registering as a retail merchant, and obtaining a Registered Retail Merchant Certificate before collecting sales tax.

Step: 3 TIN/VAT Number

The business receives an Indiana Taxpayer Identification Number and a Registered Retail Merchant Certificate issued by the Indiana Department of Revenue.

Step: 1 Standard Rate

Indiana state sales tax rate is 7%. No local sales tax applies; the rate is uniform statewide.

Step: 2 Determine if you need to register.

To calculate your tax amount, use the following formula:

 

Tax Amount= Net Price × 7%

Step: 3 Reverse Charge (B2B)

The United States does not operate a VAT-style reverse charge system. For SaaS and digital products, sellers with nexus must collect Indiana sales tax on both B2B and B2C transactions unless a valid exemption certificate is provided by the buyer. Businesses may purchase tax-exempt only if they qualify and supply proper resale or exemption documentation.

Step: 1 Selling B2C

Software that is only accessed remotely (where the user never “possesses” or downloads a copy) is not taxable in Indiana. Prewritten software is only taxable if it is downloaded or provided on tangible media. Sellers with nexus must charge 7% at the point of sale.

Step: 2 Selling B2B

Tax must also be charged on B2B SaaS sales unless the buyer provides a valid Indiana exemption or resale certificate. No reverse charge applies; responsibility remains with the seller to collect unless exemption documentation is retained.

Step: 3 Determine if you need to register.

Invoices should contain:

  • Supplier legal name and address;
  • Indiana taxpayer ID;
  • invoice date;
  • unique sequential invoice number;
  • description of SaaS/digital service;
  • taxable amount;
  • sales tax rate;
  • tax amount charged;
  • total amount due;
  • buyer name and address;
  • exemption certificate reference (if applicable);
  • currency and payment terms.

Step: 1 Filing Interval

Assigned by IDOR based on volume; typically monthly for higher liability sellers and quarterly for lower volume sellers.

Step: 2 Filing Deadline

Returns and payments are generally due on the 20th day of the month following the reporting period.

Step: 3 Submission

Filed electronically via the INTIME e-services portal. Payments accepted through ACH debit, ACH credit, or approved electronic payment methods.

Step: 4 Record Keeping

Businesses must retain sales tax records for a minimum of 3 years (longer if under audit or dispute).
