Buying a vehicle in Hawaii means navigating a system unlike any other state. While Hawaii does not technically impose a traditional “sales tax,” it does charge a General Excise Tax (GET) on vehicle purchases, which functions similarly to a sales tax—and can quickly increase your total cost if you’re not prepared.
This guide breaks down how GET works for vehicle purchases in Hawaii, highlights county-specific rate differences, registration fees, and offers expert strategies to help you save thousands on your next car, truck, or motorcycle purchase.
Hawaii Vehicle Sales Tax Overview
Hawaii does not have a standard sales tax like other states. Instead, the state collects a General Excise Tax (GET), which applies to nearly all business transactions—including vehicle sales. Here’s what you need to know:
- GET is typically 4.0% statewide, but certain counties impose a 0.5% surcharge, bringing the total to 4.5%.
- The tax is calculated on the purchase price of the vehicle.
- Unlike in other states, GET is usually embedded in the price and passed on to the buyer.
County-Level GET Surcharges in Hawaii
Hawaii’s GET surcharge varies by county, and it affects the total tax rate applied to your vehicle purchase. Here’s a breakdown:
- Honolulu County (Oʻahu): 4.5%
- Hawaiʻi County (Big Island): 4.5%
- Maui County: 4.0%
- Kauaʻi County: 4.5%
Because these surcharges are added at the county level, the effective tax rate you pay depends on where the sale takes place.

How Vehicle Tax Is Collected in Hawaii
When you purchase a vehicle from a dealer in Hawaii, the GET is typically included in the total purchase price. It’s not separately itemized like traditional sales tax. However, the dealership is responsible for paying the GET to the state, and they pass this cost to you in the final price.
For private party sales, buyers must pay a use tax equivalent to the GET (either 4% or 4.5%) when they register the vehicle at the county DMV office.
Other Vehicle Fees and Costs in Hawaii
Beyond GET or use tax, Hawaii buyers should expect to pay several additional fees at the time of registration:
- Title fee: $5 to $10 (varies by county)
- Registration fee: $45 base + county weight tax
- County weight tax: Based on vehicle weight (usually $0.0125 to $0.0175 per lb annually)
- License plate fee: ~$5

Tips to Save Thousands on Hawaii Vehicle Tax
- Buy in a 4.0% County If Possible
Purchasing your vehicle in Maui County, which does not have a 0.5% surcharge, could save hundreds on large purchases compared to Oʻahu or Big Island. - Confirm If GET Is Included
Ask the seller (especially dealers) if the GET is included in the price or added afterward. This affects your financing and closing costs. - Use Trade-Ins Strategically
While trade-ins don’t reduce the GET base, they can help you reduce the overall amount financed—lowering the total tax-related burden indirectly. - Avoid Penalties by Registering Quickly
For private sales, registering within the required timeframe ensures you avoid late fees and potential penalties. - Consider Weight-Based Registration
Because registration fees in Hawaii are weight-based, selecting a lighter vehicle can reduce your ongoing costs significantly.

What This Means for Your Vehicle Purchase
Hawaii’s General Excise Tax system may not be labeled as “sales tax,” but the effect is largely the same—and the costs can add up fast. Because rates vary slightly by county, being intentional about where and how you purchase your vehicle can result in meaningful savings.
Whether you’re buying from a dealer or private seller, or registering a vehicle after a move, understanding the breakdown of GET, weight-based registration, and title fees is essential. Small planning steps can yield big savings when it comes to GET and related costs.
