I have been searching for some clarity on this thing for a while now, but with no luck. I'm probably just not looking in the right place or something. Correct me if I'm wrong, but as I understand it, you only get the full $7500 if you owe the federal government at least $7500 when you file your taxes. This is the difference between a tax "credit" and a tax "rebate." A "credit" is not a refund but a "rebate" is money you actually get back even if you don't owe the federal government anything when you file your taxes. So if I purchase a Tesla this year, should I be doing anything I can to increase the taxes I owe around tax time next year? I read I should claim as many allowances on my W-4 as possible to ensure that I owe at least $7500 come tax time next year. But I've read conflicting opinions on this, too. Some say that it doesn't make a difference. Does it matter? If not, what does? Will claiming a lot of allowances prevent me from getting the credit? What can I do to get as much of that $7500 as possible? My wife and I both work normal jobs with salaries and we file jointly, in case that influences anything. Please forgive my terrible ignorance on this issue. I appreciate any helpful feedback.
