I checked also, bottom line is you are right, it is not worth the complications it can create. It created other probems I was told with Estate inheritance later down the road also.
Here are some edited comments from my accountant. (very good BTW)
The state gets all over out of state purchases to avoid sales tax.
Motor homes, boats and airplanes are most common efforts. There are
some very specific rules and it can be avoided but I am not sure if
Sean would get the credit.
It may be tax and income based, not a refundable credit. Is it
refundable or another credit like the charging station. They brag to
give a credit, then manipulate calculation to avoid it. You
need income tax to offset.
Boats and motorhomes need to stay out of the state I think six months.
Not a lot of bragging rights on a Tesla if you can't drive it.
My thought is just buy it.
Depending on which model and options, cost is $75 to $100K.
Because estates can be large and very taxable be careful
Currently, over 4 million is taxed at 55% and is offset (the 4 mil is
reduced for lifetime gifts.) If you pass $75K or so off now as a gift,
that reduces your the tax free amount later. It adds it to your
taxable and tax free calculations later. It will cost you 55% at
present rates later. Not a good swap. Save 7500 now, lose $41250
later.
Worse, ______ estate would be reduced in the future for the same $75K
when he gives the car back to you so the gov might collect the 82,500,
more than the the the car, 55% from each estate.
If the estate tax issue is included, you are likely to end up losing
$82,500 to save $7500.
Take the hit now. Drive the little battery powered rocket an extra
$7500 worth. At the price, that is only a few additional trips round
the block.
I am not sure what school would say about any education breaks if
there was a tesla listed as the student's personal vehicle. Might
cost you more there too. They might not think he needs any tuition
breaks.
Tax minimization is not the goal, income maximization is second.
Personal enjoyment is first.
My tax accountant tells me that is correct. The "Gift Tax" covers material goods such as cars, not just money. BTW, transferring back to you at a later point in time may make your son liable for another chunk of gift tax, depending on how much time has passed and the value of the car at that point.
