How to Complete Idaho ITD Forms for Vehicle Title and Registration

Titling and registering a vehicle in Idaho runs on a small set of Idaho Transportation Department forms filed with your county assessor’s motor vehicle office. The core Idaho ITD vehicle title and registration forms are the title application (ITD 3337), the bill of sale (ITD 3738) when a released title isn’t available, the limited power of attorney (ITD 3368) for mail-in filings, the release of liability (ITD 3858) after a sale, and the motor vehicle records request (ITD 3374). Every form is a free PDF on the ITD website or a paper copy at any county office, and several related transactions can now be completed through the ITD online portal.¹

Title Application: Form ITD 3337

Form ITD 3337 is the document you file to put a vehicle in your name, whether you bought it from a private seller, received it as a gift, or moved to Idaho with a vehicle titled in another state. Idaho Code § 49-504 sets the required contents: your full legal name, Idaho driver’s license number (or Social Security number or ITIN), your physical address, and a full description of the vehicle including make, model year, identification numbers, and the odometer reading at the time of transfer.² Businesses use their employer tax ID number in place of the SSN.

Section 1 of the form covers the vehicle description: the full VIN, model year, make, body type, model name, color, and weight where applicable.³ Trucks need a fuel type. Trailers, ATVs, and UTVs need actual weight, length, and width. Boats use their own codes for hull material, horsepower, and propulsion type, all laid out in the instructions.

The odometer reading goes in Field 18, rounded to whole miles with no tenths. Check one status box: “Actual” for a true reading, “Not Actual” if the odometer has been replaced or is known to be wrong, or “In Excess” if it has rolled over its mechanical limit.³ Leave the field blank only if the vehicle has no odometer. Federal odometer disclosure rules under 49 CFR Part 580 exempt vehicles 20 model years old or older, so a 2006 or earlier model year vehicle in 2026 needs no mileage statement.⁴

File the application with a county assessor’s motor vehicle office within 30 days of the transfer date. Missing that window adds a $20 late-filing penalty on top of the normal fees.⁵ For a private-party purchase, bring the existing title with proper release signatures from the previous owner and any lienholder. Every signature on the application must match the names printed on the previous title. A mismatch there is one of the most common reasons county offices reject applications at the counter.

Bill of Sale: Form ITD 3738

The bill of sale isn’t part of every title transaction. ITD’s guidance says to use Form ITD 3738 when a properly released title cannot be obtained, for example if the seller lost the title or one was never issued.⁵ When it is needed, the county will also require a Conditional Title Statement of Facts alongside it. The bill of sale itself records the seller’s name, the buyer’s name, the vehicle description, the selling price, and the date of sale.⁶ The price matters at the counter: Idaho charges 6% sales tax on vehicle transfers based on the purchase price.

Limited Power of Attorney: Form ITD 3368

Form ITD 3368 is a limited power of attorney tied to one specific vehicle. Its most common use is narrow but practical. If you apply for a title by mail, this form authorizes the county assessor to sign the application on your behalf.⁵ It can also authorize another person or firm to act as your representative. The form must fully describe the vehicle and be signed by the owner. When the representative signs title documents, they write the owner’s name followed by their own signature, for example, “Sharon Smith by Jane Doe, POA.”⁷

Release of Liability: Form ITD 3858

When you sell or transfer a vehicle, Idaho Code § 49-526 requires you to file a release of liability within five days of delivering the vehicle to the buyer.² Filing it protects you from responsibility for tickets, accidents, or parking violations tied to the vehicle after the sale. The statement must include the VIN, vehicle description, your name, the buyer’s name and address, the date of sale, the odometer reading, and the sales price.

Form ITD 3858 handles the filing. Mail or bring the completed form to your local county assessor’s motor vehicle office with a $3.50 fee by check or money order payable to the DMV.⁸ You can also file it online through the ITD portal at dmvonline.itd.idaho.gov, which returns an immediate confirmation.¹ Licensed dealers are exempt from filing releases on dealer-to-dealer transfers, though they keep internal records of those transactions.

Motor Vehicle Records Request: Form ITD 3374

The current records request form is ITD 3374, not ITD 3194 as older references sometimes list. It covers driving histories, title record summaries, and registration information.⁹ You provide the requestor’s name, a driver’s license number or SSN, a physical address, and a delivery preference (mail or email). A printable driver license record costs $10.50.

Access to personal information in these records is restricted by the federal Driver’s Privacy Protection Act (18 U.S.C. § 2721). Permitted uses include government agency functions, court proceedings, insurance underwriting, vehicle safety and recall matters, and employer verification of commercial driver information. If you don’t qualify under one of those categories, the department releases only non-personal information, and the form has a checkbox for that limited request.

Fees You Should Expect

Idaho’s base state title fee is $14, and each county adds its own administrative surcharge on top. Total title costs range from $14 in counties with no surcharge, such as Bannock, Boise, and Camas, up to $32.75 in Blaine County, which adds $18.75. Most counties fall in the $19 to $25 range.¹⁰ These figures cover only the title itself. They do not include 6% Idaho sales tax on the purchase price or vehicle registration fees.

Recording a lien on an existing Idaho title costs $14 and can be mailed to ITD’s Vehicle Services Section at P.O. Box 34, Boise, ID 83731-0034, or submitted through your county office.⁵ A Transitional Ownership Document, used to perfect a lien when the title isn’t available within the 30-day window, costs $26.

Registration fees vary by vehicle. Passenger vehicles are assessed by age and value. Motorcycles are $25. Utility trailers run $5 per year or $20 for five years. Boats start at $30 for vessels up to 12 feet, with $2 added per additional foot.¹¹ County registration admin fees, separate from the title admin fees, add another $3 to $14 depending on where you file.

Where and How to Submit

County assessor motor vehicle offices handle the bulk of in-person title and registration work across Idaho’s 44 counties. These offices are run by either the county assessor or the sheriff, depending on the county.¹² Search for the nearest office and its hours at itd.idaho.gov/dmv-locations. Bring original documents, not photocopies, and a valid form of payment. Most offices accept checks, money orders, and credit or debit cards, though card acceptance varies by county.

For mail-in filings, title applications go to your county assessor’s motor vehicle office. Lien recordings and certain specialized filings go directly to ITD’s Vehicle Services Section at P.O. Box 34, Boise, ID 83731-0034.⁵ Include a completed ITD 3368 with a mailed title application so the county assessor can sign for you. Use permanent ink, and double-check every signature against the names on the existing title before sealing the envelope.

The ITD online portal at dmvonline.itd.idaho.gov handles registration renewals, release of liability filings, registration of a vehicle purchased from an Idaho dealer, license plate orders, and downloadable receipts and DMV documents after a transaction posts.¹ Original title applications for private-party purchases still require an in-person or mail-in filing because the county needs to inspect the physical title with wet-ink signatures.

After You Submit

Once the county accepts your title application and payment, the title is processed and typically mailed the business day after the issue date.¹³ Expect the paper title within about a week of filing in most cases, assuming no errors. If a lienholder is recording a lien through Idaho’s electronic lien and title program, the title stays paperless until the lien is paid off, at which point ITD prints and mails the title the following day.⁵

If the department finds a discrepancy, it will contact you by mail or electronic notification asking for a correction. Common problems that cause rejections are signatures that don’t match the names printed on the previous title, a missing odometer status checkbox, and failing to include the Power of Attorney form with a mailed application. Fixing an error means resubmitting the corrected documents, which resets the processing clock.

Heavy Vehicles Need Federal Tax Proof

If you are titling or registering a heavy highway vehicle with a taxable gross weight of 55,000 pounds or more, Idaho requires proof that you have paid the federal Heavy Vehicle Use Tax before the state will complete the registration. The tax is reported on IRS Form 2290, and the IRS returns a stamped Schedule 1 as proof of payment.¹⁴ The tax period runs July 1 through June 30 of the following year. Bring the stamped Schedule 1 to the county assessor’s office with your other registration documents. Without it, the office cannot process the registration for vehicles in that weight class.
