That 1990s Super Nintendo System you've been eying on eBay for $79.97 might soon include an extra fee for sales tax, thanks to a bill up for consideration in the Senate this week. Senators are wrapping up discussions about the Marketplace Fairness Act, better known by its nickname, the Internet Sales Tax. A vote to move forward with considering the bill is expected Friday morning. The proposed legislation would force many online retailers to begin collecting taxes on their wares. Any online store that makes more than $1 million annually in online sales would have to send taxes back to the states where their goods are delivered, based on the rates required in those jurisdictions.
