About the Sales Tax

Sales taxes are applied to the transfer of goods (and sometimes services) to the end consumer in most of the fifty states, and are collected by the vendor from their customers and remitted to the state taxation department on a regular basis. Therefore, most sales tax related tax forms are applicable to businesses, and not private individuals.
