Online Filing Through the Department's Web Site
To register for the Business Tax Online Filing service, you must create a TN.gov account. TN.gov accounts allow you to enter, store, and manage information needed for accessing TN.gov services. Once your TN.gov account is set up, you can add or remove services at any time. New filers can create a TN.gov account by clicking on the "New users must register" link at https://apps.tn.gov/biztax/.
If you currently file Sales and Use Tax Online, you can add the County and City Business Tax service to your Tn.gov account and use the same login/password for both applications. Go to https://apps.tn.gov/biztax/instructions.html and check County and City Business Tax Service to add this service to your current login/password.
