OK, obviously I need to explain a bit futher. :redface:
I understand that someone earning $41k/year probably isn't going to buy a Model S. I used that example because the $7,500 rebate would result in them paying zero income tax (due to it being a tax credit).
As a better example let's say a couple, filing jointly, is paying taxes on $250,000 in 2011:
($17,000 minus 0) x 10% : $1700
($69,000 minus $17,000) x 15% : $7,800
($139,350 minus $69,000) x 25% : $17,587.50
($250,000 minus $139,350) x 28% : $30,982
Total: $58069.50
After the tax credit they pay $50,569.50. In order for this imaginary couple to pay that amount in taxes
without a tax credit they would have to earn $223,215:
($17,000 minus 0) x 10% : $1700
($69,000 minus $17,000) x 15% : $7,800
($139,350 minus $69,000) x 25% : $17,587.50
($223,215 minus $139,350) x 28% : $23,482.20
Total: $50569.70
This means that a couple earning $250,000 is
essentially getting $26,785 in income tax-free by using the $7,500 rebate, that's 357%
more than the "face value" of the rebate.
I hope that helps clarify my position a bit.
