- Local tax: Counties may levy a surcharge of up to 0.5% on the GET by ordinance (HRS 46-16.8, authorized through December 31, 2030); the GET is imposed on the seller's gross proceeds rather than on the buyer, so the amount shown on a dealer invoice depends on the dealer's pass-on practice.
- Trade-in: HRS 237-3 excludes from a dealer's gross income the later resale of an article taken in trade only 'if the full sale price of the new article is included', which means the full price of the vehicle sold is taxable and the trade-in allowance does not reduce it.
- Doc fee: No statutory cap found; the Motor Vehicle Industry Licensing Act (HRS chapter 437) search surfaced no documentary fee limit, and CarEdge lists no cap for Hawaii. CarEdge's report of 93,200 verified quotes (July 2025 to September 2026) puts the average doc fee in Hawaii at $476.
- Registration: State components: $46 flat annual registration fee (HRS 249-31) plus state vehicle weight tax of 1.75 cents per pound up to 4,000 lb, 2.00 cents per pound for 4,001 to 7,000 lb, 2.25 cents per pound for 7,001 to 10,000 lb and a flat $300 over 10,000 lb (HRS 249-33, https://data.capitol.hawaii.gov/hrscurrent/Vol04_Ch0201-0257/HRS0249/HRS_0249-0033.htm). Each county council adds a county registration fee and county weight tax (HRS 249-13). Honolulu example from https://www.honolulu.gov/csd/mvinformation.html: county registration fee $20, highway beautification fee $10, annual emblem $0.50, plate $5 when issued, and for a 3,320 lb vehicle state weight tax $58.10 and county weight tax $232.40, roughly $367 in total. min is the state flat fee only; max is left null because the total depends on weight and county.

Hawaii car tax questions
Does Hawaii charge sales tax on a private-party car sale?
No. No GET is due on a casual sale between individuals; the buyer pays only the county title transfer and registration fees. A 4% use tax (plus county surcharge) applies instead when a vehicle is bought out of state and imported for use in Hawaii.
Does Hawaii give a trade-in credit on car sales tax?
No. Hawaii charges tax on the full purchase price; a trade-in lowers what you pay the dealer but not the tax. HRS 237-3 excludes from a dealer's gross income the later resale of an article taken in trade only 'if the full sale price of the new article is included', which means the full price of the vehicle sold is taxable and the trade-in allowance does not reduce it.
What is the dealer doc fee cap in Hawaii?
Hawaii sets no legal cap on dealer doc fees. Dealers typically charge $476. No statutory cap found; the Motor Vehicle Industry Licensing Act (HRS chapter 437) search surfaced no documentary fee limit, and CarEdge lists no cap for Hawaii. CarEdge's report of 93,200 verified quotes (July 2025 to September 2026) puts the average doc fee in Hawaii at $476. If the dealer will not drop the fee, ask for the same amount off the price.
Do local sales taxes apply to car purchases in Hawaii?
Yes. Counties may levy a surcharge of up to 0.5% on the GET by ordinance (HRS 46-16.8, authorized through December 31, 2030); the GET is imposed on the seller's gross proceeds rather than on the buyer, so the amount shown on a dealer invoice depends on the dealer's pass-on practice.
How much does a car title cost in Hawaii?
$10 (flat). Hawaii has no state DMV; each county registers vehicles, so the City and County of Honolulu (Oahu) fee table is treated as the primary source. Hawaii, Maui and Kauai counties set their own fees and were not checked.
How much is annual car registration in Hawaii?
$46+ a year for a passenger car, by weight. State components: $46 flat annual registration fee (HRS 249-31) plus state vehicle weight tax of 1.75 cents per pound up to 4,000 lb, 2.00 cents per pound for 4,001 to 7,000 lb, 2.25 cents per pound for 7,001 to 10,000 lb and a flat $300 over 10,000 lb (HRS 249-33, https://data.capitol.hawaii.gov/hrscurrent/Vol04_Ch0201-0257/HRS0249/HRS_0249-0033.htm). Each county council adds a county registration fee and county weight tax (HRS 249-13). Honolulu example from https://www.honolulu.gov/csd/mvinformation.html: county registration fee $20, highway beautification fee $10, annual emblem $0.50, plate $5 when issued, and for a 3,320 lb vehicle state weight tax $58.10 and county weight tax $232.40, roughly $367 in total. min is the state flat fee only; max is left null because the total depends on weight and county.
