Idaho License Plate Transfers

Idaho's plate transfer rule surprises a lot of people the first time they sell a car: the plate does not go with the vehicle. It stays with you, the seller, unless you're dealing with one specific category of vehicle.

Under Idaho Code 49-431, license plates remain with the seller of a vehicle, not the vehicle itself. The seller can then have that plate transferred to another vehicle they own. The buyer of the vehicle registers it under their own name and either transfers one of their own existing plates or is issued a new one.

Restricted Use plates, issued for ATVs, UTVs, and off-road motorcycles, work differently. These plates stay with the vehicle rather than the seller, so if you buy a used ATV, the Restricted Use plate already on it typically transfers along with the sale rather than needing to be reassigned by the previous owner.

• Visit your county assessor's motor vehicle office in person.
• Bring the title or Manufacturer's Certificate of Origin for the new vehicle.
• Bring proof of current Idaho insurance on the vehicle receiving the plate.
• Pay the tag transfer fee along with any registration or title fees due on the new vehicle.

The transfer fee itself is small, but it's rarely the only cost involved. If the new vehicle needs a new title, or if your filing falls outside the 30-day window, standard title fees or a late penalty apply on top of the transfer fee.

Yes. Buyers generally have 30 days from the date of transfer to file the required title and registration documents with a county assessor's office. Filing after that window adds a $20 late-filing penalty, separate from whatever registration fees are already due.

Yes. Specialty and personalized plates transfer using the same process as a standard plate. Their annual fee continues on the new vehicle at the next renewal, and you do not need to reapply for a personalized combination you already hold.

If you buy from an Idaho dealer, the dealer typically prepares the title application on your behalf and files it within the required window. If you buy from a private seller, the responsibility to file within 30 days falls on you, the buyer, unless a financial institution with a recorded lien is handling the paperwork.

Can I keep my old plate if I move to a different Idaho county?
Yes. The plate stays assigned to you regardless of which county you move to within Idaho, though you'll want to update your address with your new county assessor's office.

Does the plate transfer if the new vehicle is titled under a different name?
No. The name on the new vehicle's title has to match the name the plate is currently registered to for an automatic transfer. A different name, even a family member's, generally requires new registration instead.

What happens to my plate if I don't replace the vehicle right away?
You can hold onto it and transfer it later when you acquire a new vehicle, as long as you keep it current with the state in the meantime.
