EV Registration Fees in Hawaii
Hawaiiis one of the states that charges electric vehicles extra at registration — typically justified as replacing the gas taxes EVs don't pay. Here's exactly what it adds for a two-year-old $45,000 vehicle:
| Fuel type | Annual registration cost | vs. gas |
|---|---|---|
| Gas | $46.00 | — |
| Plug-in hybrid | $46.00 | same |
| Battery EV | $96.00 | +$50.00 |
The EV-specific line items
- Electric vehicle fee$50.00
Hawaii combines a $46 state registration fee (raised July 2025) with state weight taxes (1.75–2.25 cents per pound) and county weight taxes — Honolulu's is 7 cents per pound, so a 3,500-lb car on Oahu pays roughly $300+ more in weight taxes plus about $32 in other county fees. EVs pay a $50 state surcharge or can opt into the new per-mile road usage charge (capped at $50).
