Hawaii Vehicle Registration Cost Calculator by Island

How much does it cost to register a car in Hawaii?

A new $30,000 car costs about $1,747.75 to register in Hawaii the first year, plus a local tax that varies by county, then about $382.75 a year to renew. The first year adds the sales or use tax on the purchase, the title and the plate, one-time charges you do not pay at renewal.

Same car, four islands: the county weight tax compared

Every county charges its own weight tax per pound on top of the state's. Here's what that means for the 3,320 lb car Honolulu uses in its own example:

The state's part is the same on every island: the $46 fee plus 1.75 cents a pound, or $104.10 on this car. On Oahu the county then adds a $20 registration fee, and with the $10 highway beautification fee and a 50 cent emblem the bill lands at $367. Maui also charges electric cars $100 a year and hybrids $50.

Oahu drivers nearly got a break. A 2026 bill, HB 2022, would have capped Honolulu's rate at 1.75 cents, the same as the state's. It passed both the House and the Senate, then died in April when the House rejected the Senate's changes, so the 7 cents still applies. One exemption worth knowing: a Hawaii resident on active duty, or in a Guard or Reserve unit based in Hawaii, pays no weight tax on one vehicle with Form CS-L (MVR) 50A.

The safety check: $25.75, every year

You can't renew or transfer a car in Hawaii without a current safety inspection certificate, and the station won't inspect it without Hawaii insurance. Since July 1, 2025 the check costs $25.75 for a car or truck and $17.75 for a motorcycle, the first increase since 2017. It's yearly, except for a new car: its first safety check is good for two years.

For an electric car the inspection now does a second job. The station records the mileage, which feeds the Hawaii Road Usage Charge. At renewal an EV owner picks the flat $50 or $8 per 1,000 miles, capped at $50, and from July 1, 2028 every EV moves to the per-mile charge. Hybrids and plug-in hybrids aren't part of it.

Shipping a car to Hawaii: your first 30 days

1. The clock starts on the bill of lading. You have 30 days from the arrival date shown on it.
2. Insure it and get a safety check. The car needs both plates fitted, or it won't pass.
3. Pick plates or a permit. You can register it with Hawaii plates straight away, or pay $5 for an out-of-state permit and keep your mainland plates until they expire or for 12 months, whichever comes first.
4. Take the paperwork in. The out-of-state title and registration, the bill of lading and the inspection certificate go to your county's motor vehicle office. On Oahu that's a satellite city hall, booked through AlohaQ.

Tax catches people who buy a car just before the move. There's no use tax on a car you bought and drove while living on the mainland, but if you bought it less than three months before shipping, Hawaii presumes you bought it for use here and charges 4% on its landed value. Sales tax you already paid to the other state counts against that, and Form G-27 is how you prove either case. Renewals after that are in the renewal section below, and the tax on a car you buy here is on the Hawaii tax, title and license page.

Buying the car as well? The tax on the purchase is a separate, one-time bill, about $1,125 on a $25,000 car in Hawaii. For your own price and trade-in, and what a dealer adds on top, use the Hawaii tax, title and license calculator.

How to register a car in Hawaii

If you have just bought a car, here is the whole process in Hawaii, from insurance to plates.

1. Line up Hawaii insurance. Set up auto insurance that meets Hawaii minimum coverage. Most offices will not register a car without proof of active insurance.
2. Gather your documents. You usually need the signed title, or the manufacturer's certificate of origin for a new car, plus a bill of sale, proof of insurance, and photo ID.
3. Get the inspection. Hawaii requires a safety inspection. The fee and the schedule are in the inspection section of this page.
4. Apply at Hawaii DMV. Submit the title and registration application with your documents, online, by mail, or in person, whichever Hawaii DMV offers.
5. Pay the fees. Pay the registration, title and plate fees, plus the sales or use tax on the purchase. The calculator at the top of this page gives your exact total.
6. Get your plates and registration. Hawaii DMV issues your plates and registration. Keep the registration document in the car and fit the plate or sticker as directed.

Putting the car in your name

The title is the document that says who owns the vehicle; the registration is what lets you drive it. Transferring the title into your name costs $10 in Hawaii and is a separate transaction with its own paperwork and deadline. For the forms, who has to be present, and how a family gift is taxed, use the Hawaii title transfer calculator. Buying from a private seller? Our private car sale guide covers the paperwork and the tax, and the branded title guide explains salvage and rebuilt titles.

How much are license plates in Hawaii?

A standard plate is $5. source 5 An initial plate fee of $5.00 applies only when new plates are issued. In Hawaii the plates normally stay with the car when it is sold.

Electric and hybrid vehicles

Hawaii charges $50 a year on top of the normal registration for an electric vehicle. It is a flat charge that stands in for the fuel tax an electric car does not pay, billed every year. Full detail and how it compares with other states is on the Hawaii EV registration fees page.

Renewing your registration in Hawaii

A renewal costs about $356.50 a year on a typical car. That figure is for a 3,200 lb car on Oahu. The 3,320 lb car Honolulu uses in its own example comes to $367, and every other county charges far less weight tax than Oahu. The tax, title and plate were one-time charges, so they do not come round again. For your own car, work out your renewal in the calculator at the top of this page.

1. Watch for the renewal notice. Hawaii DMV sends it before your registration expires, and renewing early does not move your renewal month.
2. Have the details ready. Your plate number, the last digits of your VIN or title number, proof of insurance, a passing inspection if your county requires one, and a way to pay.
3. Renew online, by mail or in person. Online through Hawaii DMV is fastest and gives you a receipt straight away; you can also mail the notice with payment or renew at an office or authorized agent.

Registering a car in Hawaii from another state

Moving in with a car you already own is a different transaction from buying one. You are not making a purchase, so there is usually no full sales tax to pay on it again.

There is no use tax on a car you bought and used in another state while you lived there. If you bought it less than three months before shipping it, Hawaii presumes it was bought for use here and charges 4% use tax on its landed value, less any sales tax you paid to the other state. source 8

What you will still pay in Hawaii is the title, which is $10, and the registration itself. Expect a check that the VIN on the car matches the title, since Hawaii has not seen this vehicle before.

Register a car you ship to Hawaii within 30 days of its arrival, counted from the date on the bill of lading. Bring the out-of-state title and registration, the bill of lading and a Hawaii safety inspection (the car needs both plates to pass). If you want to keep your mainland plates for now, a $5 out-of-state permit covers the car until those plates expire or for 12 months, whichever comes first. source 8

Registering or renewing late in Hawaii

Hawaii has no grace period. Registration is due by the last working day of the expiration month (the next working day if that falls on a weekend or holiday), and after that a flat $16 penalty applies to a passenger car.

Hawaii registration is due by the last working day of the month on your emblem. Pay after that and a flat $16 penalty is added for a passenger car ($8 county weight tax penalty plus $8 state weight tax penalty). Buy a car whose registration has lapsed and you are billed for every year it went unregistered.

Driving on an expired registration is a ticket in every state, and in some places grounds for a tow, so renew as soon as you can and keep the receipt. What happens with an expired registration in each state is in our expired registration guide.

Are Hawaii registration fees tax deductible?

Probably not. Hawaii charges a flat registration fee that is the same whatever the car is worth, so there is no value based portion to deduct.

The IRS test has three parts, and a charge has to meet all three. It must be based only on the value of the property, it must be charged to you on a yearly basis, and it must be imposed on personal property. A flat fee fails the first part. A one off charge fails the second.

Two practical points that catch people out. It is an itemized deduction, claimed on Schedule A, so it is worth nothing to you if you take the standard deduction. And it counts against the same state and local tax cap as your income and property taxes, which is $40,000 for 2026, or $20,000 if you are married filing separately.

The sales tax you paid when you bought the car is a different question with a different answer, and so is a car used for business. We set out the rule and where each state falls on it, but we are not tax advisers and this is not advice about your return. The state by state breakdown is here.

Exemptions and low sale prices

Not every change of owner is a sale, and the tax follows what actually happened rather than what the paperwork looks like. A car handed over for nothing is a title transfer matter; see how Hawaii taxes a gifted car.

Hawaii taxes what you actually paid, which makes the bill of sale the document that decides your tax. That cuts both ways: an honest low price is accepted, and a dishonest one is fraud rather than a clever move. The value the state uses if it decides to look is its number, not yours.

Inheritances, active duty military exemptions, disabled veteran plates, salvage titles and temporary permits all change what you pay, and none of them is automatic. Hawaii DMV publishes the conditions for each, and every one of them has to be claimed.

What you need to bring to Hawaii DMV

Your county motor vehicle office (Honolulu, Hawaii, Maui or Kauai). Hawaii runs vehicle registration at the county level. New residents register within 30 days of bringing a vehicle into the state. source 1

Hawaii names these specifically: The Certificate of Title signed by the seller (Section A) and by you (Section D), the last Certificate of Registration, and a current Hawaii safety inspection certificate. A new car not registered by the dealer uses the Application for Registration, Form CS-L (MVR) 1. source 6

Beyond whatever Hawaii DMV lists for your transaction, almost every counter visit needs the same six things (the full checklist, state by state, is in what you need to register a car):

• The title certificate, signed over to you by the seller. On a brand new car this is the manufacturer's certificate of origin instead.
• A bill of sale showing the price, the date and both names. In Hawaii this is the document your tax is worked out from, so the figure on it matters.
• An odometer disclosure, usually printed on the title itself. Federal law requires it on most vehicles under 20 years old.
• Proof of insurance that meets the Hawaii minimum, in your name, for this vehicle.
• Photo identification, and proof of your Hawaii address if your license is from somewhere else.
• Payment. Many county offices do not take credit cards, or charge extra for them.

Depending on the vehicle and the county you may also need an inspection certificate, an emissions test, or a VIN verification. Hawaii DMV publishes the checklist for each transaction type, and it is worth reading it the day before rather than in the queue. What each state inspects, and what it costs, is on the car inspection cost by state page.

Why is car registration so expensive in Hawaii?

Because most of what you are paying is not registration. On a $28,000 car in Hawaii, tax is about 77% of the total bill. The registration fee itself is the small line.

Three things drive the number up:

• The tax on the purchase. Charged once, on the price of the car, at the same sort of rate as anything else you buy.
• The county weight tax. Your county charges it by the pound every year on top of the state's weight tax, so a heavy car costs more at every renewal, and the same car costs more in one county than another.
• No trade-in credit. Hawaii taxes the full price even when you hand over another car, which on a typical deal is worth hundreds of dollars.

The part you can actually control is the timing and the paperwork. Registering late adds penalties, getting the trade-in structured as one transaction protects the credit where one exists, and knowing the figure before you walk in stops a dealer's estimate from becoming the number you accept.

What the Hawaii fee names mean

The wording on a registration bill is not consistent between states, which is half of why the whole thing is confusing. Here is what each term on a Hawaii bill actually is.

Hawaii calls its agency Hawaii DMV. The names change state to state, and so do several of the charges above. There is a full glossary of registration and title fee terms covering the ones Hawaii does not use.
