Sales Tax Filing Services

Sales tax is a tax on the sale of goods and services collected by state and local governments. However, there is no universal "federal" sales tax in the United States. Instead, each state—and often individual counties and municipalities within those states—has its own unique sales tax rates, rules, and filing frequencies.
