Vehicle Registration in Kauai County
In Kauai County, vehicle owners must register within 30 days of purchase, lease, or relocation. The process starts by submitting a registration application (Form REG‑1), proof of ownership, and a valid driver’s license to the county DMV office or the local tax assessor’s office. Once the paperwork is verified, the DMV applies the applicable fee schedule. Typical fees range from $70 for a small commuter car to $200 for heavy trucks, plus a state plate fee of $40. All registrations receive a county control number that must be displayed on the vehicle’s rear plate.
Factors That Affect Your Fees
Fees are based on three primary criteria: vehicle value, weight, and age.
- Value: Vehicles priced above $30,000 attract a 5% surcharge, adding roughly $100 to the base fee.
- Weight: Heavier vehicles (over 6,000 lbs) fall into higher fee tiers— a 12,000‑lb pickup may cost about $350 versus $150 for a compact.
- Age: A depreciation schedule grants a 1% discount per year of ownership, so a ten‑year‑old car can see a 10% reduction on its base fee.
Special Considerations
Additional fees apply in certain circumstances.
- Emissions Testing: Passenger vehicles are exempt, but commercial and fleet vehicles pay a $25 testing fee.
- Special Plates: Custom or commemorative plates add $10–$20 per year.
- Transferring from Another State: Out‑of‑state titles require a $30 title transfer fee.
- County Surcharge: Residents in designated “green zones” face a $15 environmental surcharge to fund local conservation projects.
