Verified July 2026
No state purchase rebate — every 2026 rebate bill died in session. The EV math here is Hawaii's brutal gas prices vs. cheap off-peak charging, plus a $500 charger rebate if you're on Kauai.
The $7,500 federal new-EV credit and $4,000 used-EV credit ended September 30, 2025 — and the federal home-charger credit (30C) followed on June 30, 2026. If anyone tells you otherwise, they're reading an old script. (Charger installed on or before June 30, 2026? That one's still claimable on that year's return — IRS Form 8911.)
No state-level purchase incentive right now — the money in Hawaii, if any, is at the utility level.
No cash rebate — the "Smart Charge Hawaii" incentive closed to new enrollment in Nov 2024. What matters: the "Shift and Save" time-of-use rate makes overnight charging dramatically cheaper than daytime.
The catch: Hawaii charges EV owners an extra $50/yr at registration.
The $50/yr is Hawaii's Road Usage Charge (live since July 2025): at renewal you pick a flat $50 or $8 per 1,000 miles capped at $50. Per-mile becomes mandatory for EVs by 2028 — the gas-tax replacement is coming for everyone eventually.
