Thanks for this
@O. horridus - I wasn't aware of the change in format, and assumed that because it is still called a tax credit, it worked in the traditional way. With few details available, it's difficult to tell how the new scheme will work though.
Rebates come at the end of the sale as a lump sum to the buyer; if they're "point of sale" appears to be the case here, it's immediate. This scheme still uses the words "tax credit" however, which make things really murky. A tax credit reduces the amount of tax owed, so it would follow that you will still need to have a tax liability of at least $7,500 to use the full credit. Yet this too seems be changed in the new bill, with at least one article I found seeming to indicate that it was available regardless of your tax liability. While both a rebate and tax credit reduce the out of pocket cost to the buyer, since neither represents a discount to the actual sales price, the buyer is still on the hook for state sales tax calculated at full vehicle price (at least in most states).
Since the scheme appears to combine aspects of both a rebate and a credit, perhaps we will need to change the terminology and call it a "redit". Here's a small amount of detail from an
article in InsideEVs (7/28):
"Finally, it appears the credit may be offered like a rebate at the point of sale, rather than as a credit at tax time. This would be huge since many people can't afford to finance an expensive EV and then wait until tax time to be "reimbursed." Moreover, since the current credit depends on an applicant's individual tax liability, many people can't get the credit anyhow. If you don't have $7,500 in tax liability, you're not going to get a $7,500 tax credit. However, a point-of-sale credit could work much differently."
