Hawaii rental car taxes and fees typically add about 26% to the advertised daily rate. The three government-imposed charges are a $7.50-per-day rental motor vehicle surcharge, a General Excise Tax passed through at roughly 4.712% of the base rate, and, at airport pickup locations, a $4.50-per-day customer facility charge. Rental companies usually tack on their own recovery fees as well. On a five-day airport rental at $60 per day, that works out to roughly $79 in added charges before you add insurance or equipment.
The $7.50 Daily Surcharge
The largest add-on most renters see is the rental motor vehicle surcharge tax under Hawaii Revised Statutes Chapter 251. For 2026, it runs $7.50 for every day, or any partial day, that a vehicle is under contract.1Hawaii Department of Taxation. Form RV-2 Instructions The charge applies to every rental transaction statewide, whether you pick up at a major airport counter or a small off-site lot.
The rate is on a scheduled climb. It started at $5.00 per day, and beginning January 1, 2022, the legislature set an automatic $0.50 annual increase each January through December 31, 2027.2Justia. Hawaii Code 251-2 – Rental Motor Vehicle and Tour Vehicle Surcharge Tax So the 2027 rate will be $8.00 per day. Every dollar collected goes into the state highway fund for road and bridge work across the islands.3Hawaii Department of Taxation.

The General Excise Tax Pass-On
Hawaii has no conventional sales tax. Businesses instead pay a General Excise Tax on their gross income for the privilege of operating in the state, and the base rate for retail transactions including car rentals is 4%.4Hawaii Department of Taxation. Hawaii Code 237 – General Excise Tax Law State law lets rental companies pass the tax to the customer as a visible line item, and essentially all of them do.
The math is slightly counterintuitive. When a business visibly passes GET to the customer, the tax itself becomes part of the gross receipts on which GET is calculated, so the pass-on rate ends up higher than the nominal tax rate. Each of Hawaii’s four counties adds the full 0.5% county surcharge, bringing the combined rate to 4.5% and the maximum amount the company can charge you to 4.712% of the pre-tax price.5Department of Taxation. County Surcharge on General Excise and Use Tax Because every county now charges the same surcharge, picking one island over another won’t save you anything on tax.
One useful detail: when the $7.50 daily surcharge is separately stated on your receipt, that amount is excluded from the gross income subject to GET.6Cornell Law Institute. Haw. Code R. 18-251-2-05 – Surcharge Tax on Rental Motor Vehicles; Subject to General Excise Tax You won’t pay GET layered on top of the surcharge. GET does apply to the base rental, any optional insurance or damage waivers, and most other charges on the contract.
The Airport Facility Charge
Pick up at a state airport and you’ll pay another $4.50 per day. This customer facility charge is authorized under Hawaii Revised Statutes Section 261-7 and funds the design, construction, and operation of the consolidated rental car facilities (CONRACs) at major terminals.7Justia. Hawaii Code 261-7 – Operation and Use Charges It applies for every day or partial day the vehicle is under contract.
The charge only hits airport pickups and returns. Renting from an off-airport location that doesn’t rely on airport shuttle services or infrastructure avoids it entirely. On a seven-day rental, that’s a $31.50 difference. Off-airport locations sometimes offset the savings with higher base rates or less convenient logistics, so compare the full quote rather than any single line.
Company-Added Fees to Watch
Beyond the government charges, rental companies typically add their own line items. The most common is a vehicle license recovery fee, usually $0.50 to $2.00 per day, that offsets the company’s fleet registration costs. Hawaii charges a $46 annual registration fee per vehicle, plus deposits into the state highway fund and emergency medical services fund.8Justia. Hawaii Code 249-31 – State Registration Fee Spread across a fleet, those costs add up, and companies pass a fraction to each renter.
Unlike the surcharge or GET, these recovery charges are not required by Hawaii law. The amount varies by company, and some agencies also tack on energy surcharges, airport concession recovery fees, or administrative fees. Scrutinize them when comparing quotes.
If You Use a Car-Sharing Service
Peer-to-peer and membership-based car-sharing programs follow a different surcharge structure. Qualifying car-sharing organizations are charged $0.25 per half-hour (or any portion of a half-hour) that a vehicle is rented, instead of the $7.50 daily rate.9Hawaii Department of Taxation. Form RV-3 Instructions A two-hour errand runs $1.00 in surcharge, which is much cheaper than the daily flat rate.
Once a car-sharing rental hits six hours, though, the standard $7.50 daily surcharge applies instead.9Hawaii Department of Taxation. Form RV-3 Instructions Programs qualify for the lower rate only when they meet specific criteria, including self-service access for dues-paying members, usage-based billing by the hour or minute, no separate written agreement for each rental, and an average paid-use period across the fleet of six hours or less.3Hawaii Department of Taxation.

What a Sample Bill Looks Like
Here’s a five-day rental on Oahu at a $60-per-day base rate, picked up at Daniel K. Inouye International Airport:
- Base rental: $60 × 5 = $300.00
- Rental motor vehicle surcharge: $7.50 × 5 = $37.50
- Customer facility charge: $4.50 × 5 = $22.50
- GET at 4.712% on $300: approximately $14.14
- Vehicle license recovery fee (estimate): approximately $5.00
That’s roughly $79 added to the $300 base, a 26% increase before any optional insurance or equipment. The surcharge tax alone accounts for nearly half of it. On a two-week rental at the same daily rate, the surcharges and fees would run about $158. Checking the total out-the-door price, not just the daily rate, is the only reliable way to compare quotes across companies and islands.
