American car buyers have been participating in a slow and steady . While our and offerings still have a way to go, those who have recently bought a new electric car or plug-in hybrid may be eligible for some credits come tax time. and when you bought it.

For those of you about to file for the 2022 tax year who bought a car last year, there could be an extra $7,500 headed to your pocket from Uncle Sam — provided that you bought the right car at the right time.

Up until the signing of in , the eligibility for the Federal Tax Credit on EVs was fairly straightforward. According to the Internal Revenue Service, the requirements for an individual were that you must use the vehicle for personal use and it must be primarily used in the United States. For a vehicle to qualify, it must have been produced by an automaker that has sold fewer than . Essentially, if you bought an EV that , you probably qualified.

Things got tricky when the was signed into law on August 16th, 2022. This bill eliminated the 200,000-unit cap on brand eligibility, which to those automakers that were quick to get EVs on the market. Most of the new rules put into place by the Inflation Reduction Act don’t go into effect until 2023, except the “final assembly” clause, which took effect immediately.

This clause excluded all electrified vehicles from qualifying for the tax credit if they were not produced in North America. Under the previous regulations, 75 electric vehicles on sale in the U.S. were eligible for the tax credit, but this new clause This new legislation was meant to encourage buyers to purchase EVs, particularly those build in the U.S., , since the final assembly clause combined with the battery sourcing requirements will have the long-term effect of disqualifying more EV models.

These new rules really threw a wrench into the plans of a lot of buyers who had EVs or PHEVs on order from any of a number of automakers, but were still waiting for those cars to arrive at dealerships. Luckily, the :

“If you entered a written binding contract to buy a vehicle before August 16, 2022, but took possession on or after August 16, 2022, and before January 1, 2023, you may claim the credit based on the prior rules and disregard the assembly requirement.”

A lot of dealers got wise to this, and described their “order deposits” as “binding agreements” to allow these customers to qualify, provided that they took delivery of the car before the end of 2022.

If you purchased an EV in 2023, or if you plan to, the effect of the Inflation Reduction Act on EV tax credits is still a bit murky. Between January and March of 2023, the , meaning cars that previously didn’t qualify may now qualify for the tax credit — if purchased within this timeframe. However, the MSRP caps of $55,000 on sedans and $80,000 on SUVs would still be in place.

One of the upsides to the Inflation Reduction Act is that it offers up to $4,000 in tax credits for buyers who purchase a used EV. However, there are some additional caveats: The vehicle must be at least two years old, it must be purchased from a dealer, and the person filing for the tax credit must come in under one of the various income thresholds, depending on filing status.

Of course, this EV tax credit thing is just one more instance of American tax law being needlessly complicated. If you think you may qualify for an EV credit, it’s always wise to consult with a tax professional.
