Congress has cleared and President Trump has signed the sweeping One Big Beautiful Bill Act. From electric-vehicle perks that vanish next fall to an across-the-board pruning of renewables incentives, here’s the fast-moving checklist every driver, homeowner, and investor needs to know.
$7,500 New-EV Tax Credit Ends 9/30/25
Buy a new electric car before September 30, 2025 to claim the full federal incentive. After that date, the credit disappears, effectively raising sticker prices overnight.
$4,000 Used-EV Credit Sunsets the Same Day
The popular incentive for pre-owned EVs follows the same countdown. Close on a purchase before September 30, 2025 or kiss the discount goodbye.
No Annual $250 EV Fee
An earlier proposal to impose a $250 yearly registration fee on EV owners was dropped from the final bill—so no extra hit at DMV.
30% Rooftop-Solar Credit Ends 12/31/25
Homeowners must have rooftop solar systems in service by December 31, 2025 to earn today’s 30 % federal tax break. Installations completed afterward won’t qualify.
ZEV Credits Crater: CAFE Penalties Axed
The bill reduces Corporate Average Fuel Economy fines to $0, wiping out a key reason automakers bought Zero-Emission Vehicle credits from companies like Tesla.
ZEV Credits Crater: State Waivers Revoked
Congress also voided EPA waivers that let California and 17+ follower states enforce stricter ZEV mandates. Without state-level pressure, demand for ZEV credits could collapse—court challenges pending.
Home-Geothermal Credit Terminates 12/31/25
Tax incentives for geothermal heat pumps and related home systems vanish after December 31, 2025.
Battery-Manufacturing Credit Survives—With Tougher U.S.-Content Rules
The lucrative 45X production credit (up to $45/kWh) remains, but battery cells/modules must be 60% U.S. content in 2026, rising to 85 % by 2030. Plants relying heavily on foreign equipment could miss out.
Commercial & Lease-EV Credit Canceled 9/30/25
Businesses, fleet operators, and leasing companies lose their clean-vehicle credit after September 30, 2025.
New Auto-Loan Interest Deduction (2025-28)
For personally owned vehicles that undergo final assembly in the U.S., borrowers can deduct up to $10,000 in annual interest through 2028 (income phase-outs start at $100k single / $200k joint).
Advanced-Manufacturing Credit: Wind Components Sunset After 2027
The production credit for wind-turbine parts expires at the end of 2027 and excludes facilities using certain China-linked components.
Clean-Electricity Credits Phase Out After 2027
Wind and solar farms must either break ground within a year of enactment or enter service before December 31, 2027 to retain production/investment credits. Nuclear, geothermal, and battery projects get a longer runway but face tougher “foreign-entity-of-concern” limits.
Efficiency & Home-Energy Credits Wind Down
- Home-improvement credit for audits and upgrades ends 12/31/25.
- Energy-efficient new-homes credit ends 6/30/26.
- Alt-fuel refueling property credit (e.g., EV chargers) ends 6/30/26.
- Clean-hydrogen credit: projects must start construction by end-2027.
Bottom Line
Most consumer-friendly clean-energy perks vanish in the next 24 months, while manufacturing incentives stay—but only for firms meeting stiff domestic-content rules. If you’re planning to buy an EV, go solar, or build a wind farm, the clock is ticking.
