If they can tell you credits are available they can tell you they either are, or are not, subject to the AMT. What is "complex" about this? It's very straightforward. In practice they'll use your suggestion and tell you about the credits in order to close the sale but then conveniently neglect to mention the AMT part. How convenient.EVDRIVER said:Car dealerships should not be commenting on AMT or tax details in any way, the most they should disclose is that there are credits available and one should "consult their tax professional" for details,
You see the same thing with the EVSE credits. Lots of advertising saying you can get a tax credit but nothing pointing out, even in the fine print, that the credits are subject to the AMT.
No one is asking them to do your taxes for you. However, dissemination of selective pieces of information can be misleading, and in this case they're intentionally trying to mislead you into thinking you can get a credit that you may or may not be able to get. You may think this is fine but, as applied to the earlier tax credits for hybrids, it was just another sleazy car dealer practice.
An honest practice would have been to say: "There is a $3500 tax credit for this car. But the credit is subject to the Alternative Minimum Tax. " After that they can say "you'll need to figure that out" or "consult your tax professional" (as if most people have one of these) or whatever else they want to say. But at this point they've alerted you to the possibility that you wouldn't be able to take advantage of the credit. They've been honest and how it's up to you to figure it out.
