The "BUSINESS TAX",  applies to most businesses.  But don't confuse that with the Tennessee Franchise & Excise Tax 

The business tax is imposed generally on anyone delivering goods or services to Tennessee customers, but a number of activities and entities are specifically exempted. For example, taxpayers are exempt from the business tax if they generate less than $10,000 in sales.  Manufacturers are exempt from Business Rax also. These are licenses to do business in specific counties and cities.

You have to get these licenses in each county you do business, and renew each year by april 15. These are based on Sales...has nothing to do with profits.

The Tennessee Franchise & Excise tax is applicable for Corporations, S-Corps, and LLCs,  The Franchise & Excise Tax is NOT applicable for sole proprietors, as Tennessee has no personal income tax.
