I have to check with my accountant regarding the $7500 federal tax credit on the Model S. I was talking to two different auto dealers (Toyota and Chevy) regarding the Pruis plug-in model and the Volt. The dealers indicated there is a federal tax credit for the vehicles. However, they stated that if one is subject to the Alternative Minimum Tax, you lose the federal tax credit. Anyone know whether this is correct. I have been subject to the Alternative Minimum Tax for years (an assume many on this site are also subject to it), and if the tax credit is lost, the cost of the Model S has just become $7500 more expensive than I expected. Any accountants out there?
