The $7,500 rebate does not really "exist" in 2023. There is a BIG misconception about it and the news reporting on it.
It's split into two.
$3,750 is based on % of battery components being made in North America. NO car including tesla meets this requirement, nor will in the next year.
The 2nd half, $3,750 is based on the car components being made in America, Tesla does meet that. So the most you could get is $3,750. If you meet income limits and car price cap limits.
BUT, its only if you owe taxes at the end of the year. Meaning if you owe $5K in taxes for 2023, the IRS would deduct $3,750. If you owe no taxes, then you get NO credit! Nothing. Most people with company jobs do not owe taxes, they actually get a refund. So you would get nothing back.
Starting in 2024, is when the $7,500 credit converts to an instant point of sale discount when you buy a car. But again, that will depend on battery components, so you will only get $3,750 off at point of sale most likely. The reason that does not start until 2024 is because the IRS/treasury has to setup a system/website for dealerships to opt into and get the immediate discounts/credit. Its in the works still.
