#5 - Sales Tax:

“The city of Chicago previously had the highest total sales tax of all major U.S. cities (10.75%), which was a major reference point until the rate was decreased to 9.75% as of July 1, 2010.”

L.A. is similar: it tacks on an added tax to the state tax. Sales tax in many L.A. areas is 9.75%.

Funny, as many believe Hawaii is such a tax hell hole, but it's sales tax is a bit under 4%.
