Car Rental Business Regulations in Hawaii

Hawaii requirements at a glance

What is the Hawaii rental motor vehicle surcharge?

$7.50 for each day or any portion of a day in 2026, rising by fifty cents to $8.00 on 1 January 2027. It is levied on the lessor, not charged to the renter by law.

A minute counts as a day

A day is any twenty-four hour period, and one minute or more of a period counts as a full day. There is no proration at the daily level.

Car sharing is charged by the half hour

A car-sharing organisation pays $0.25 per half hour or portion of one, which reverts to the full daily surcharge once a rental reaches six hours. For short bookings that is a substantial difference, and it is the reason hourly products are viable in Hawaii at all.

Who it applies to, and who is exempt

The surcharge applies to vehicles rented or leased for six months or less, designed to carry seventeen passengers or fewer. Exempt are mopeds, trucks with a nominal capacity of 1,000 lb or more fitted with a cab-cargo barrier, cargo vans with two seats or fewer, vehicles supplied with a driver, replacement vehicles provided while a lessee's own vehicle is under repair or has been stolen or written off, and complimentary vehicles where no consideration is received. For replacement vehicles keep the repair order, stolen vehicle record or total loss claim for two years. The renter's own nonprofit or tax-exempt status does not exempt the rental.

The pass-on trap that costs money

Because the surcharge is levied on you, it forms part of your gross income for General Excise Tax purposes unless it is separately stated and visibly passed on by a registered lessor. Fold it into the rate and you pay General Excise Tax on it as well. Separate it properly and you do not. This is the single most expensive configuration error available in Hawaii.

How does the General Excise Tax apply to rentals?

Hawaii has no sales tax. The General Excise Tax is a tax on your business measured by gross income, at 4 percent plus a 0.5 percent county surcharge. You may pass it on, but you may not represent it to the customer as a government charge on them.

The distinction is not academic

A sales tax is a tax on the customer that you collect. The General Excise Tax is a tax on you that you may recover. Describing it on an invoice as a tax the customer owes misstates what it is, and Hawaii takes that seriously.

The maximum you can visibly pass on is 4.7120 percent

Because the pass-on is itself part of gross income, the arithmetic produces a maximum visible pass-on rate of 4.7120 percent in all four counties rather than a flat 4.5. Charging more than that is not permitted.

County surcharges are 0.5 percent everywhere now

All four counties now levy 0.5 percent, Maui having joined on 1 January 2024, and all four run to the end of 2030. The surcharge applies only to activities taxed at 4 percent.

What licenses do you need to rent cars in Hawaii?

A General Excise Tax licence at $20, and a separate Rental Motor Vehicle, Tour Vehicle and Car-Sharing Vehicle Certificate of Registration, also $20. Operating without the certificate is a misdemeanor.

Register before you start, not after

The certificate must be obtained before commencing business, and separately for each place of business in the State. It must be displayed at each place of business and it is not transferable. You must notify the Department within ten days of ceasing business, transferring ownership, reorganising or changing name.

The certificate reaches peer-to-peer platforms too

The registration requirement covers anyone providing rental motor vehicles to the public, tour vehicle operators, car-sharing organisations and peer-to-peer car-sharing programs. A platform operating in Hawaii is inside it.

Your agreement has to be filed before you use it

A lessor may not offer any rental agreement or damage waiver unless a specimen has first been delivered to the director of the Department of Commerce and Consumer Affairs. This is a genuine pre-clearance step that no other state in this batch requires, and changing your agreement means filing the new version.

What can you charge a Hawaii renter?

Only the quoted rate, plus a short list of permitted visible pass-ons. Hawaii prohibits additional mandatory charges, which means every charge required in order to rent must already be inside the daily rate.

This is stricter than almost anywhere else

The daily or periodic rate must include every charge required to rent, with the exception of the specific pass-ons the statute permits. Quotes, including those given in advertising and over the telephone, must disclose all payments required. A young renter fee charged as a separate line item is not among the permitted pass-ons, which makes that common practice a compliance risk in Hawaii even though no statute sets a minimum rental age.

What you may pass on visibly

Rents or fees paid to the Department of Transportation under concession contracts, service permits, or rental customer facility charges may be visibly passed on, provided the amount is attributable to the particular transaction, does not exceed your net payments to the Department, is supported by accountant-verified reports filed with the Department and the tax director within three months of the period end, and uses a stated per-lessee methodology. Vehicle licence recovery fees are also contemplated, tied to the annual registration fee and weight tax actually paid for that vehicle.

Calling a pass-on a government charge is a per se violation

Representing a visible pass-on as mandatory, or as a government assessment on the consumer, is expressly a per se violation of Hawaii's unfair practices statute. So is misstating material elements of the transaction, stating that a damage waiver is mandatory, charging more than repair cost or actual cash value or diminished value, charging more than a reasonable estimate of actual lost income for loss of use, or charging more than actual towing charges.

Fuel charges are capped

A refuelling charge may not exceed the average locally prevailing self-service retail price plus a surcharge of no more than half that price, and fuel credits must be at no less than the prevailing retail price. Hawaii is one of very few states to regulate the refuelling markup directly.

What are the Hawaii damage waiver rules?

The waiver must be disclosed as optional in at least 10-point boldface with the actual daily charge stated, it may not exclude ordinary negligence, and you may not take a deposit or card hold against damage.

The deposit prohibition is absolute

A lessor may not require a deposit or advance charge against the lessee's credit card in any form for damage to a vehicle in the lessee's possession, custody or control. Nor may you require payment for damage on return until the cost and the lessee's liability are agreed or legally determined. Massachusetts prohibits a deposit where the renter declines the waiver; Hawaii prohibits it outright.

What the disclosure must say

In plain language and at least 10-point boldface: that the waiver is optional, that it carries an additional charge, the actual daily charge, all restrictions and conditions, that the lessee may already be covered and should check their own policy and deductible, that the lessee may be liable for damage, and the statutory acknowledgment. The agreement may not contain unreasonable restrictions.

Ordinary negligence cannot be carved out

A waiver may not exclude damage caused by ordinary negligence. The same rules extend to lessors or limited line rental company producers offering or selling collision insurance, so you cannot route around the waiver rules by selling a product under a different name.

What insurance is required for rental vehicles in Hawaii?

40/80/20 for policies effective on or after 1 January 2026, doubled from 20/40/10. Personal injury protection remains at least $10,000.

This is a doubling, and it applies on renewal

The limits doubled across the board. They apply to new and renewal policies effective on or after 1 January 2026, so a fleet policy renewing later in the year picks up the new floor at renewal rather than on 1 January. No further increase is scheduled in the statute.

How does Hawaii treat peer-to-peer car sharing?

As a separate regime. The rental industry chapter expressly does not apply to peer-to-peer car sharing, but the tax does: sharing is subject to both the General Excise Tax and the daily rental surcharge.

Hosts pay the surcharge, unlike in several other states

Hawaii subjects peer-to-peer car sharing to the General Excise Tax and to the rental motor vehicle surcharge, with the program collecting and remitting. That is the opposite of Pennsylvania and Tennessee, both of which exempt car sharing from their rental taxes, and of Washington, where sharing falls outside the rental car tax until 2027.

The program must ensure insurance, which is not the same as providing it

The program must ensure that during each sharing period the shared car is insured. The Insurance Commissioner has clarified that ensure means make certain: the program need not itself insure the vehicle, but it must provide the coverage where the owner's or driver's insurance has lapsed, excludes coverage, or does not provide what is required. The agreement must clearly designate who is responsible for primary coverage, and any ambiguity is construed against the program.

Six years of records

Records must be collected, verified and kept for not less than six years. That is the longest fixed retention period in this batch, against three years in Ohio and Michigan.

The rest of the framework

Lienholder notice, required disclosures, driver licence verification, responsibility for installed equipment, safety recall duties, and a vicarious liability exemption. A shared car expressly excludes rental vehicles, which is how the two regimes are kept apart.

Frequently asked questions

• 1What is the Hawaii car rental surcharge in 2026?+

  $7.50 for each day or any portion of a day, rising to $8.00 on 1 January 2027. It is levied on the lessor rather than charged to the renter by law, and a minute or more of a twenty-four hour period counts as a full day.

• 2Does Hawaii have sales tax on car rentals?+

  No. Hawaii has a General Excise Tax on your gross income at 4 percent plus a 0.5 percent county surcharge. You may pass it on, up to a maximum visible rate of 4.7120 percent, but you may not describe it to the customer as a government charge on them.

  Because it is levied on you, it counts as part of your gross income unless it is separately stated and visibly passed on by a registered lessor. Fold it into the rate and you pay General Excise Tax on it too.

• 4Can I charge a young renter fee as a separate line in Hawaii?+

  It is a compliance risk. Hawaii prohibits additional mandatory charges, so any charge required in order to rent must be inside the quoted daily rate, and an age-based fee is not among the permitted visible pass-ons. No Hawaii statute sets a minimum rental age.

• 5Can I take a damage deposit or card hold in Hawaii?+

  No. A lessor may not require a deposit or advance charge against the lessee's credit card in any form for damage to a vehicle in their possession, custody or control, and may not require payment for damage on return until the cost and liability are agreed or legally determined.

• 7Do Turo hosts pay the Hawaii rental surcharge?+

  A General Excise Tax licence at $20 and a separate Rental Motor Vehicle, Tour Vehicle and Car-Sharing Vehicle Certificate of Registration, also $20, obtained before commencing business and displayed at each location. Operating without it is a misdemeanor.
