I am surprised the EV tax credit still exists. Even though it looks to be progressive (bigger % help to lower cost vehicles) it's really regressive because of the excess tax credit issue. "Only rich people can really benefit from it." A local news channel did a hatchet-job story about Tesla buyers and tax credits in Seattle.
While it's certainly unfortunate that folks who don't owe at least $7,500 in taxes for the year can't take full advantage of the ACES Act Plug-in Electric Vehicle credit (which is $7,500 for a new Tesla, Leaf, or Volt), I don't think that means it is "regressive".
(Technically, I don't think a
credit program can ever really be "regressive" by definition, since a tax is only "regressive" when it uses a rate that decreases as the taxpayer's income increases. And the tax credit calculation is effectively agnostic regarding the taxpayer's effective tax rate.)
Regardless of whether you think that's just "semantics", it is definitely a shame that the ACES Act PEV credit isn't also a
refundable tax credit, which would mean any "excess" credit amount remaining after the owed tax for the year is reduced to $0 becomes available as a tax refund. I blame Congress for that...and the rest of the mess that is the US Tax Code.
But that doesn't mean the PEV credit is a "bad" idea or a bad program...and it's pretty much complete FUD to have it spun as "it only benefits rich people", especially when the way the available credit is calculated is completely divorced from the cost of the vehicle!
One other tidbit on the ACES Act PEV tax credit that most people don't know (
source):
As defined by the 2009 ACES Act, a PEV is a vehicle which draws propulsion energy from a traction battery with at least 4 kwh of capacity and uses an offboard source of energy to recharge such battery. The tax credit for new plug-in electric vehicles is worth $2,500 plus $417 for each kilowatt-hour of battery capacity over 4 kwh, and the portion of the credit determined by battery capacity cannot exceed $5,000. Therefore, the total amount of the credit allowed for a new PEV is $7,500.
The new qualified plug-in electric vehicle credit phases out for a PEV manufacturer over the one-year period beginning with the second calendar quarter after the calendar quarter in which at least 200,000 qualifying vehicles from that manufacturer have been sold for use in the United States.
So once Tesla has sold 200,000 qualifying vehicles (Roadster + Model S + Model X + ???), the credit will be reduced to 50% for the next two quarters then 25% for the two quarters after that...and then be gone for any and all Tesla models.
So it'll be interesting to see how close Tesla is to that 200,000 mark by the time the lower-cost Gen III Tesla is introduced!
