Register a vehicle in Idaho

Title and register a vehicle in Idaho: who files the title, the 30-day deadlines, the documents and the fees as the DMV states them.

Your situation

How did you get the vehicle?
Online or in person
Not for a first registration · County motor vehicle officeThe DMV pages say you can renew a registration online. They do not say a new title or registration can be done online. Without a lienholder, you file the title documents with a county assessor's motor vehicle office within 30 days of transfer to avoid a $20.00 late-filing penalty.
Cost
$14 title fee + county admin feeThe DMV's title fee table shows each county's title admin fee, added to $14.00. Registration fees vary by vehicle age, type or weight, inspection requirements and county; the DMV lists them on its registration page.

Your plan

  1. Gather your documents

  • Filing a title more than 30 days after transfer carries a $20.00 late-filing penalty.
  • The vehicle must belong to an Idaho resident or business to be registered in Idaho.
  • A used vehicle bought from a private party needs the existing title signed by the previous owner or lienholder.
