Typical Fee Breakdown

In Lemhi County, IDAHO, vehicle registration fees are typically composed of a base registration fee, a county road and bridge fee, and a percentage based on the vehicle's assessed value.

Vehicle Registration in Lemhi County

In Lemhi County, vehicle registration follows Idaho’s state‑wide framework, but with a few local nuances that can affect the final cost and required paperwork. After purchasing a vehicle or moving into the county, you must file a new registration application with the Idaho Transportation Department (ITD). The application can be submitted at the local Lemhi County Tax Assessor’s Office, any licensed ITD location, or through the ITD online portal.

Every vehicle requires a registration fee that covers the annual license plates, license tax, and other state fees. Typical fees for a passenger car in Lemhi County range from $60 to $120, depending largely on the vehicle’s sales price, weight, and whether it is a motorcycle or commercial vehicle. Additional fees include the County Assessment Fee of $30, which applies to all vehicles registered within Lemhi County, and the mandatory Idaho Auto Plate Fee of $25. New vehicles also incur the Vehicle Identification Number (VIN) Verification Fee of $5, while used vehicles purchased within the state have a lower verification fee of $3.

After you pay these fees, your plates are mailed within 7–10 business days. You are required to renew annually, which is the most common reason for a visit or online renewal, and you should keep track of registration stickers that appear on your bumper to avoid fines for late renewal.

Factors That Affect Your Fees

• Vehicle Value – The Vehicle Tax is calculated as a percentage of the sale price (often 6.5% for most cars). Higher value vehicles see a higher tax component.
• Weight – Commercial or heavy trucks trigger Weight-Based Fees. Light passenger engines below 3,000 pounds are taxed lower; heavier models can add $40–$100 to the base fee.
• Type of Vehicle – Motorcycles, quads, and alternates pay reduced rates. However, commercial vehicles, trailers, or specialized equipment can incur additional certification charges.
• Age – Older vehicles (<10 years) may be eligible for a Reduced Vehicle Tax Approval of up to 20% if they meet state emissions standards. Very old vehicles (older than 25 years) may qualify for exemption from the VIN verification fee if the plate number is unchanged.

Special Considerations

When registering or transferring a vehicle in Lemhi County, pay attention to the following:

• Special Plates – Idaho offers specialty plates for veterans, colleges, emergency services, and nonprofits. These plates carry an extra fee of $75 per year plus a one‑time $25 registration fee.
• Interstate Transfers – Vehicles brought from out of state must submit title documentation, a valid out‑of‑state registration, and a proof of E‑mail of a NOM tax deposit (NOM). The County imposes an additional Homage Transfer Fee of $35.
• County Surcharges – Lemhi County levies a flat Infrastructure Improvement Surcharge of $15 on all new registrations to fund road maintenance projects.
