Yeah but I’m not sure, because if you have a binding contract put into place on the day of enactment(August 16th), then that contract was established prior to “immediately after enactment of the Inflation Reduction Act(after August 16, 2022)”.Looks very clear to me. If you purchased a vehicle on the 16th, you're fine. If you purchased after the 16th, you would have had to have a binding agreement in place before the 15th. Those are two separate ideas with different dates.
Of course, the IRS changed "treat such vehicle as having been placed in service on the day before the date of enactment" to "the rules in effect before the enactment of the Inflation Reduction Act for the EV credit apply", which is very different.
If the contract was established before the new rule, do you really think upcoming guidance will enforce that rule on that contract? I think as long as the vehicle is delivered by December 31, 2022 it may still qualify.
