Become an Approved Software Vendor

The Department of Revenue provides software certification services free upon request to registered Tennessee vendors.  If you are currently registered with the Department of Revenue, please provide your sales and use tax account number when requesting certification.  If you are not currently registered with the Department of Revenue, you may do so by registering for a sales tax account through the department’s portal https://tntap.tn.gov/eservices/_/

Once you have registered, please contact Efile.Questions@tn.gov for access to the specifications.
