House bill HR 5376 on 10-28-21
Correct me if I'm wrong, but the bill seems even better for Tesla than the original credit of $7500. As I read it, the total credit a Tesla could qualify for would be $12,500. Here is the breakdown:
$4,000 for any plug-in (PHEV or full electric) within certain limits.
$3,500 more for a 40 kWhr or greater battery and a gas tank no greater than 2.5 gallons (I guess this eliminates current PHEVs).
$4,500 more for domestic assembly (I don't see the Union made requirement anymore).
$500 more for "domestic content" (this used to be for US made battery).
I still see the $69K MSRP limit for an SUV, $55K for a sedan, and $74K for a truck.
I still see income limits of $800K for filing joint and $400K for single.
