The Internet Taxman

While America doesn’t have a national sales tax, some state officials have spent the last 15 years scheming to devise a more unified sales tax regime so they can force mail-order and online sellers to collect sales tax for states where they have no operations. And now some in Congress appear ready to lend them a hand with legislation that would bless state efforts to impose taxes on interstate commerce, something usually blocked by the Commerce Clause of the Constitution.
