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.
Amazon tax Many U.S. states have passed online shopping sales tax laws designed to compel Amazon.com and other e-commerce retailers to collect state and local sales taxes from its customers. Amazon.com originally collected sales tax only from five states as of 2011, but as of April 2017 collects sales taxes from customers in all 45 states that have a state sales tax and in Washington, D.C.[1] Amazon does not collect sales taxes from Alaska, Delaware, Montana, New Hampshire, and Oregon, since those states do not have state sales taxes. Additionally, approximately half of all Amazon.com purchases are sold on the Amazon Marketplace through 3rd-party vendors, and these purchases remain free of tax except for in Washington state, where these purchases (starting in 2018) are now taxed.[2][3]
