That's a reasonable first thought. When I hear "double taxation" in the US I usually think first of self-employed people sometimes having to pay both income and payroll tax compared to an otherwise employed person only paying income tax. Then maybe I think about places like Missouri where after you take your post-tax income and buy a car with sales tax on the purchase, you pay yearly for that car as a personal property tax (which does not include your license plate, or inspection, or the city sticker some local places require).
