DOR > Business Tax > Sales Tax Sales Tax

Does your business sell goods or tangible personal property? If so, you’ll need to register to collect a 7 percent sales tax. This registration gets the ball rolling so that you can legally conduct retail sales in the state of Indiana. Once your registration is completed and processed, you’ll be issued a Registered Retail Merchant Certificate (RRMC). And you’ll need one certificate on display for each business location, if you have more than one retail address.

The RRMC is valid for two years, and updates automatically with no additional charge for renewal. If a business does not pay its tax liability, the RRMC will expire. After the tax bill is paid in full, the business must file a REG-1 form that is mailed to the business and pay a $25 registration fee.

To get started, Juanita needs to file a Business Tax Application with the Department and indicate she will be collecting sales tax. Once she receives her Retail Merchants Certificate, she can then open for business.
