Online business registration with the Tennessee Department of Revenue is available for most tax types through the Tennessee Taxpayer Access Point (TNTAP). For a brand new taxpayer, click “Register a New Business” on the TNTAP homepage and fill out the information.
If you have an account and need to add a new location, you will need to login, gain access to your tax account, and add a location.
The full list of tax types available in TNTAP is here.
To register for any other tax types, please complete a paper application for registration.
