The Idaho Transportation Department's new-resident guide says you must title and register within 30 days of moving, whether or not the out-of-state registration has expired. Bring the car for a VIN inspection and an admitted-carrier policy at $25,000, $50,000, and $15,000. A separate ITD fact sheet says 90 days. Confirm which clock the county uses.
Key facts
Registration deadline
The new-resident guide says 30 days from moving, even if the out-of-state registration is still valid. A registration fact sheet on the same department's site says 90 days and defines residency as 90 continuous days at a principal home.
The guide says fees and taxes vary by vehicle type, age, purchase price, and county. It does not state a sales-tax rate or a credit for tax paid to another state.

The Idaho Transportation Department's new-resident guide says you must title and register your vehicle within 30 days of moving to Idaho, whether or not the out-of-state registration has expired. You bring the car with you. A DMV employee inspects the vehicle identification number at that visit. You also need liability insurance with an admitted Idaho carrier at $25,000 for injury or death of one person, $50,000 for two or more persons, and $15,000 for property damage.
A second ITD document does not use 30 days. The registration fact sheet dated in the file path July 2025 says a new resident must register and title within 90 days of moving, and that an Idaho resident is anyone whose principal home has been in Idaho for 90 continuous days, although residency may be declared earlier. Use the county office to resolve the conflict. This page will not pick one number and drop the other.
Tell your insurer you have moved, so the policy is with an admitted carrier. Idaho checks coverage electronically.
Gather the title, the registration, identification, and, if someone else still holds the title, the lienholder's name and address.
Take the vehicle to the county DMV. The employee inspects the VIN. If the title is not in your name, it must be signed, with the price on the title or on a bill of sale.
Order plates and pay the fees and taxes the county calculates. Plates are mailed. Allow six weeks, and track the order in the DMV online portal.
After that first visit, the online portal can handle renewals. The first login asks for your Social Security number so the account matches the DMV record.
The guide does not describe a safety inspection or an emissions test. The inspection it does describe is the VIN check done by the DMV employee while the vehicle is there. If the title was lost, you apply for a duplicate from the state that issued it before Idaho can title the car. The guide does not mention a bonded-title process.
Offices are county sheriff or assessor offices, not one state counter. Check the locations page, because some offices do not offer both driver licenses and vehicle services, and some require appointments.
The guide says to bring cash, a check, or a credit card, and that fees and taxes vary by the type of vehicle, its age, the purchase price, and the county. It does not state a statewide sales-tax percentage, and it does not state whether tax you paid in another state is credited. The department's page does not state the credit. Ask the county office when it calculates the bill.
Students attending an Idaho college or university, and active-duty members and their dependents, do not need an Idaho driver license if the out-of-state license is valid. That sentence is in the license section. The vehicle section still says to title and register within 30 days of moving, and it does not carve those groups back out. The fact sheet says Idaho residents who are temporarily in another state, including students or military, may request titles and registrations by mail. That sentence is about people whose home is already Idaho, not about newcomers who want to keep another state's plates.
A shipped car still has to be at the county office for the VIN inspection the guide requires, unless the office accepts another method the guide does not describe. The 30-day sentence runs from moving, not from driving across the border. See car shipping in Idaho and the cost calculator.

Questions
Is the deadline 30 days or 90 days?
The "New to Idaho" guide, opened November 10, 2026, says you must title and register within 30 days of moving, whether the out-of-state registration has expired or not. ITD's registration fact sheet, posted as a July 2025 PDF, says a new resident must register and title within 90 days, and that a resident is someone whose principal home has been in Idaho for 90 continuous days, though residency may be declared sooner. The department's pages do not agree. Ask the county DMV which deadline it enforces.
What do I bring?
Bring the vehicle for a VIN inspection by a DMV employee. Bring the current title and registration. If the title is not yet in your name, it must be signed and the price entered, plus a bill of sale if the price is not on the title. If a lienholder holds the title, bring the lienholder's name and address. A lost title has to be replaced by the state that issued it. Bring personal identification.
What insurance is required?
The guide says you must tell your insurer you moved so the policy is with an admitted carrier in Idaho. Idaho verifies coverage electronically. The minimums listed there are $25,000 for injury or death of one person, $50,000 for two or more persons, and $15,000 for property damage. The Idaho Department of Insurance states the same three figures. Failure to keep insurance can result in suspension. The guide's phrase is "suspension of registration fees."
Where do I go, and what does it cost?
County offices run by the sheriff, the assessor, or both handle the transaction. Some offices do licenses only, some do vehicles only, and some do both. Some take appointments. Pay by cash, check, or credit card. Fees and taxes vary by vehicle type, age, purchase price, and county. The guide does not print one passenger-car fee. Plates are made to order and mailed. The guide says to allow six weeks.
Do students and military have to register the car?
The license section says students at an Idaho college or university, and active-duty military and dependents, do not need an Idaho driver license if they have a valid out-of-state license. The vehicle section does not repeat that exemption. It says you must title and register within 30 days of moving. Ask the county office before you treat the license exemption as a registration exemption.
