EV charging incentives by state.

California

California leads the nation in EV adoption with the most aggressive ZEV sales targets, the largest public charging network of any state, and a layered set of income-targeted purchase programs that replaced the now-closed Clean Vehicle Rebate Project.

Colorado

Colorado's EV share of new light-duty registrations peaked at 29.4% in Q3 2025, second only to California, then fell to 10.6% in Q2 2026 after the federal $7,500 credit ended and the state Innovative Motor Vehicle Credit dropped to $750 (Alliance for Automotive Innovation). Vehicle Exchange Colorado rebates for income-qualified buyers and Xcel Energy's charger rebates still cover a large share of vehicle and charger costs for those who qualify; the federal 30C charger credit ended June 30, 2026 and is no longer available.

District of Columbia

DC has one of the highest EV adoption rates in the US, driven by high incomes, federal government employment, and a 2035 ZEV mandate. There is no District EV purchase rebate, but a District tax credit covers 50% of home charger costs up to $1,000 through 2026, and a DOEE program rebates up to 80% of multifamily charger installation costs. Dense urban charging infrastructure.

Washington

Washington is among the more EV-forward states, with a statutory goal that all new light-duty vehicles be electric by model year 2030 and the Advanced Clean Cars II rules adopted starting with model year 2026. Puget Sound Energy and Tacoma Power offer residential charger rebates (Seattle City Light's and Snohomish PUD's residential charger rebates have ended), and WSDOT has awarded NEVI Round 1 funding for DC fast charging on I-90, US-97, US-195, and US-395.

Connecticut

Connecticut's CHEAPR program offers a $1,500 standard rebate for new BEVs (from October 15, 2026; $1,000 before) and up to $5,000 for income-qualified buyers of used BEVs. Eversource and United Illuminating offer up to $1,500 for chargers and wiring, but as of January 1, 2026 those rebates are limited to households at or below 300% of the federal poverty level or living in High Poverty, Low Opportunity areas.

Hawaii

Hawaii has one of the highest EV adoption rates in the US. Hawaii Energy offers rebates up to $35,000 per DC fast charger, with payments waiting on additional state funding. Hawaiian Electric's Charge Up Commercial pilot is closed to new applications. High electricity costs make rate choices important.
