Are there recent policy changes?
In November 2024, the California Air Resources Board (CARB) approved the Fiscal Year (FY) 2024-25 Funding Plan for Clean Transportation Incentives (https://ww2.arb.ca.gov/our-work/programs/low-carbon-transportation-investments-and-air-quality-improvement-program/funding). A variety of HVIP policy changes will impact Innovative Small E-Fleet (ISEF) vouchers and can be found at the webpage on HVIP FY 24-25 Funding and Policy Changes (https://californiahvip.org/im/). Key updates for ISEF include:
- New Voucher Amounts: Effective September 22, 2025, the small business voucher amounts in ISEF align with the new voucher amounts in Standard HVIP.
How do I access funds?
Vouchers are requested by working with a participating dealership and provider and the incentives are applied at point-of-sale for the purchase of eligible vehicles. More information is available on the ISEF webpage (https://californiahvip.org/purchasers/#isef).
