"The Marketplace Fairness Act is not a tax increase. It will not increase taxes on consumers. It will not increase taxes on businesses. And it will not tax the Internet or iTunes, or create a national sales tax as some have outlandishly claimed. The bill is simply a responsible, constitutional and, dare I say, “conservative” way to permit states to keep their sales tax policies up to date.
What it would actually do is give states the authority to require out-of-state sellers to collect sales tax on purchases made by their residents."
So, it's not a tax increase, but if you purchase goods online you will now have to pay taxes. Logic fail!
