You can find up-to-date information on federal and state tax incentives for EVs on the U.S. Department of Energy's Fuel Economy website. They maintain a list of eligible vehicles and outline specific eligibility requirements. Also, keep in mind that these incentives often have income and price caps, and they can vary significantly by state. Checking your state’s department of energy or transportation website can provide more tailored information. Personal experiences vary, but most find the process straightforward if you ensure all paperwork is correctly submitted.
