Hi Sam,
First, let me say it sucks they pushed you so far back in line.
I am no tax expert. But I did my own "research" last night on the rebate. Some of this I already knew, but other stuff I did not. So do you regularly pay over $7500 in Federal tax's each year? This $7500 is only a tax liability credit. So if you owe $5000 when you do your 2023 taxes next spring then you will get $5000 credit from that $7500.
Also, what is happening in March with the IRS is a bit of an unknown. They pushed the rules out until March so they can make a final decisions one the extra rules. But it looks like there is a 2 part component to the tax rebate once they make a ruling sometime in March. These newer rules which are not 100% yet, are on top of the current rules they have in place with price caps on vehicle types and income your family makes. These newer rules below focus on the battery manufacturing process.
1)A certain amount of the batteries minerals have to be processed here in the United States or with Trade Free partner countries based off of percentages and years. Starting with 2023 at 50%, 2024 60% and all the way up to 70% in 2026, then 80% after that.
2)At least 50% of the batteries in the EV must be manufactured in the United States. This also scales up year by year. 60% in 2024 and all the way up to 100% in 2029.
