where does the state get its power to regulate commerce within its borders
Commerce Clause The Commerce Clause describes an enumerated power listed in the United States Constitution (Article I, Section 8, Clause 3). The clause states that the United States Congress shall have power "To regulate Commerce with foreign Nations, and among the several States, and with the Indian Tribes." Courts and commentators have tended to discuss each of these three areas of commerce as a separate power granted to Congress.[1] It is common to see the individual components of the Commerce Clause referred to under specific terms: the Foreign Commerce Clause, the Interstate Commerce Clause,[2] and the Indian Commerce Clause.
Sales taxes in the United States Since January 2017, 5 states (Alaska, Delaware, Montana, New Hampshire and Oregon) do not levy a statewide sales tax,[1] while California has the highest state sales tax with a base rate of 7.25%. (the territory of Puerto Rico has a higher 10.5% value added tax since April 2016).[2][3] In some states such as California, counties and cities impose additional sales taxes, and total sales taxes can be over 11%.
