I think we all ready have a mileage tax, it’s called the gas tax.
This will be “in addition to”
In North Carolina, that's somewhere around 24 cents a gallon... since I get (nearly) 24 miles to a gallon, that's already a penny per mile.
Meanwhile, the business mileage reimbursements are 50.5 cents, so here we go again with whacky, knee-jerk reaction conflicting/confiscatory tax policies again. We'd better darn well start raising up some serious candidates to challenge these yahoos quick... November 2010 isn't really that far away.
