This EV tax credit calculator now starts with the current federal reality, not the old headline. As of April 4, 2026, IRS guidance says new and used clean vehicle credits are not available for vehicles acquired after September 30, 2025, so most current federal comparisons should begin at $0.
The route still has value because many users searching `ev tax credit calculator` are really asking two different questions: Is the federal credit still available today, and if I acquired a vehicle during the legacy window, did I clear the basic income and price caps? This page answers both in one workflow.
If the vehicle was acquired after the cutoff, the route shows that the federal program is unavailable under current guidance. If the vehicle was acquired on or before the cutoff, the route runs a simplified legacy cap check for new and used clean vehicles.
That makes the page more trustworthy than older EV credit pages that still imply every qualifying new EV buyer can claim up to $7,500 today. It also keeps the user from carrying a stale federal credit into broader EV-vs-gas ownership math.
Use the result as a screening step, not a filing step. VIN-level eligibility, assembly and battery rules, dealer requirements, and your actual tax situation still determine whether any legacy federal clean vehicle credit is real and usable.
