It depends on the state and if you have any employees.

I am in WA and we have to pay the following:

- WA State Sales Tax to the Dept. of Revenue

- Business and Occupation Tax  to the Dept. of Revenue

- Personal Property Tax to the county your business is located in

- Possible additional Business and Occupation taxes to individual cities you do business in.

-  For employees - 941 & 940 (IRS), WA State Unemployment and WA State Labor and Industries Taxes.

Most State's have a webstie and/or number businesses can get info from.
