Hawaii Vehicle Registration Cost

Hawaii's vehicle cost structure is uniquely complex with both STATE and COUNTY weight taxes (per pound) plus annual registrations at both levels. Honolulu County (70% of Hawaii's population) charges ~7.0¢/lb county weight tax on top of the state's ~1.75¢/lb — totaling $332/year on a 3,800 lb vehicle. Other counties charge dramatically less: Hawaii Island ~$66, Maui ~$108, Kauai ~$71 for the same vehicle. Sales tax (General Excise Tax) is 4% state + 0.5% county = 4.5%, passed through at 4.712%. Title fee is just $10. EV surcharge $50 statewide (Maui adds $100 more). A new $35,000 vehicle in Honolulu County runs about $2,067 in first-year costs, with annual renewals around $415 — among the higher recurring costs nationally due to the weight tax structure.

How Hawaii calculates registration

• State Annual Registration Fee — $46 (annual) Per HRS §249-31. State portion of annual registration. Goes to state highway fund.
• County Annual Registration Fee (Honolulu) — $20 (annual) County registration fee — varies by county. Honolulu County charges $20, other counties charge $12-$45. Funds county roads.
• Highway Beautification Fee — $7 (annual) Per HRS §249-31. Annual statewide fee for highway maintenance and beautification.
• State Vehicle Weight Tax — $2 per 100 lbs (annual) Per HRS §249-33. State weight tax progressively scaled by net weight: 1.75¢/lb for vehicles 4,000-7,000 lbs (typical passenger); 1.25¢/lb for lighter, 2.0¢/lb for heavier. Calculation here uses 1.75¢/lb = $1.75 per 100 lbs.
• County Vehicle Weight Tax (Honolulu) — $7 per 100 lbs (annual) Per HRS §249-2 and county ordinance. County weight tax varies SIGNIFICANTLY by county: Honolulu (Oahu) ~7.0¢/lb, Hawaii County (Big Island) ~1.25¢/lb, Maui County ~2.5¢/lb, Kauai County ~1.5¢/lb. Shown here is Honolulu (most populous, 70% of HI residents). Other counties pay substantially less. For a 3,800 lb vehicle: Honolulu $266, Hawaii $48, Maui $95, Kauai $57.
• Title Transfer Fee — $10 (one-time) One-time title transfer fee per Hawaii county fee schedules.
• Emblem Fee — $1 (annual) Annual emblem/decal fee.

Sales tax

Hawaii charges 4% state General Excise Tax (GET) , with typical local rates around 0.5% (range: 0%–0.5%). Trade-in credit: full. Tax basis: purchase price.

Hawaii uses the General Excise Tax (GET) instead of traditional sales tax. State rate is 4%; counties (Honolulu, Hawaii, Kauai) add a 0.5% county surcharge — Maui currently has no county surcharge. Combined typical 4.5%. Dealers commonly "pass through" the GET to buyers at a 4.712% rate (calculated to net out to 4.5% of the dealer's revenue, since dealers themselves owe GET on the full transaction). Trade-in is fully credited.

Electric vehicle surcharge

Hawaii charges an additional $50/year for electric vehicles.

Per HRS §249-31. EVs and alternative fuel vehicles pay $50/year additional statewide. Maui County ADDITIONALLY charges a $100/year highway improvement fee on EVs and $50/year on hybrids (per Ordinance 5217 of 2021).

What makes Hawaii distinctive

• Hawaii's weight tax structure makes the WEIGHT of your vehicle a primary cost driver — not the value. A 5,000-lb SUV in Honolulu pays ~$437/year just in weight tax (state + county), while a 3,000-lb sedan pays ~$262. This is unusual; most states tax by value, MSRP, or flat rate. Hawaii's structure favors light, fuel-efficient vehicles.
• Hawaii's COUNTY WEIGHT TAX varies dramatically: Honolulu (Oahu) ~7.0¢/lb, Maui ~2.5¢/lb, Hawaii (Big Island) ~1.25¢/lb, Kauai ~1.5¢/lb. The same 3,800-lb vehicle costs ~$266/yr in Honolulu county weight tax but only ~$48 on the Big Island — a $218/year difference based purely on which island you live on.
• Hawaii does NOT have a traditional sales tax — instead, the General Excise Tax (GET) is a tax on BUSINESS GROSS REVENUE that dealers typically pass through to consumers. Effective rate of 4.712% (rather than the headline 4.5%) reflects the dealer needing to net 4.5% after their own GET liability.
• Hawaii requires ANNUAL safety inspections (typically $15-$25 at certified stations) but no emissions testing in any county. Inspections must be current to renew registration. New residents have 30 days to register; if expired, back-taxes are owed for every missed year plus penalties.
• Maui County adds an EXTRA $100/year highway improvement fee on EVs and $50/year on hybrids — making Maui the highest-cost county in Hawaii for EV ownership. Combined with the higher cost of living and limited charging infrastructure, EV adoption in Maui is lower than in Honolulu where the fee is just the $50 state surcharge.
