The Idaho vehicle registration application is the form you submit to the Idaho Transportation Department (ITD) Division of Motor Vehicles to prove your car, truck, trailer, or motorcycle is legally allowed to drive on Idaho roads. You file it through your county assessor’s motor vehicle office, by mail, or online through your DMV account, and you must first hold an Idaho title (or apply for one using the Application for Certificate of Title, ITD 3337) before the state will register the vehicle.
Getting this form wrong is not a small thing. A name that does not match your driver’s license, a missing lien release, or a late filing can stall your registration for weeks and add penalty fees on top. Idaho processes hundreds of thousands of vehicle transactions each year, and filings made more than 30 days after a purchase trigger a mandatory $20.00 late title penalty that many drivers never see coming.

What the Idaho Registration Application Is and Who Must File It
The Idaho vehicle registration application is the official request that places your vehicle in the ITD’s records and authorizes it for use on public roads. Registration is separate from titling: a title proves you own the vehicle, while registration proves the vehicle is allowed to drive. In practice, both happen at the same counter, because Idaho will not register a vehicle that does not already have an Idaho title or a pending title application on file.
The form is required by Idaho Code Title 49, which governs motor vehicles and gives the ITD authority to register them. The agency that receives your form is your local county assessor’s motor vehicle office, which acts as the ITD’s processing arm. The deadline that governs the form is tied to your purchase or your move: new residents must title and register within 90 days of establishing residency, and buyers must title within 30 days of purchase to avoid the late penalty.
Almost every vehicle owner must file. This includes Idaho residents who buy a car from a private seller, new residents bringing a vehicle from another state, people who inherit a vehicle, and businesses that own fleet vehicles. Dealers usually prepare and file the title application for you when you buy from a dealership, but the registration renewal each year remains your responsibility. If you skip registration, driving the vehicle is an infraction with no grace period in Idaho.
Several related forms interact with the main application. The ITD 3337 is the Application for Certificate of Title, the ITD 3367 (Rev. 12/23) is the Duplicate Idaho Title Application for a lost or destroyed title, the ITD 3369 transfers ownership on a duplicate, and the ITD 3239 updates your address. Knowing which form you actually need saves a wasted trip to the county office.
Before You Start: Documents and Information You Need
Idaho requires you to prove who you are, that you own the vehicle, and that the vehicle is insured before it will register anything. New residents must obtain an Idaho driver’s license before they can register or title a vehicle, so handle that first. Walking in without one of the items below is the single most common reason people get sent home and have to return another day.
Gather these items before you open the form:
- Your Idaho driver’s license or ID card number. The form asks for it in the owner section, and the state cross-checks the name against its records; without it, the office cannot verify you.
- The current title or Manufacturer’s Certificate of Origin (MCO). This proves ownership; without it, you cannot title the vehicle and therefore cannot register it.
- The full Vehicle Identification Number (VIN). Every field keys off the VIN; a wrong digit links your registration to the wrong vehicle.
- The odometer reading. Federal law requires an odometer disclosure on transfers of vehicles under ten model years old, and a missing reading voids the transfer.
- Proof of Idaho insurance. Idaho requires liability coverage from a company licensed in the state, and law enforcement verifies it electronically.
- A lien release or lienholder details. If a loan was paid off, the release proves the lender no longer has a claim; without it, the title stays encumbered.
- A bill of sale. This shows the purchase price, which sets the 6.0% sales/use tax you owe at registration.
- Payment for fees. You need a check or credit card for mail filings, since the state does not accept cash by mail; missing payment stops processing cold.
Two more items help in special cases. If your name changed by marriage, bring a “One and the Same Statement” (the ITD 3125 may be used) so the name on the title matches your license. If someone else is signing for you, bring a notarized power of attorney, or the office will reject the signature.
Where to Get the Form and How to Access It
The official forms live on the ITD’s DMV website, and you should always pull them from there to be sure you have the current revision. The registrations, plates, and titles page links to the title application, the renewal portal, and supporting forms. The duplicate title form, ITD 3367, shows its revision date — Rev. 12/23 — printed at the bottom, and you should confirm that date before filling it out so an old version is not rejected.
You have three ways to get and submit the application. First, you can download and print the PDF, fill it out by hand, and bring or mail it to your county office. Second, you can pick up a paper copy at any county assessor’s motor vehicle office and complete it at the counter with staff help. Third, for renewals and many changes, you can use your online DMV account to handle the transaction without any paper at all.
County offices are listed by name on page two of the title forms, with a mailing address for each of Idaho’s 44 counties. For example, Ada County filings go to the DMV Processing Center, PO Box 140019, Garden City ID 83714, while Kootenai County filings go to the Motor Vehicle Section, PO Box 9000, Coeur d’Alene ID 83816-9000. Always send your form to the county where you live, because that is where your registration is administered and where your county admin fee is set.
If you only need to check status rather than file, the state lets you look up a title at accessidaho.org and renew registration through your DMV login. Faxed copies of the forms are not accepted, so do not waste time trying that route.
Step-by-Step: How to Fill Out the Idaho Title and Registration Application Line by Line
Because Idaho requires a title before registration, the title application is the heart of the paperwork, and its sections mirror what the registration counter needs. The walkthrough below follows the section structure used on the official Idaho title forms, including the ITD 3367 duplicate application, which shares the same owner, lienholder, fee, and signature blocks you will see on the main title and registration paperwork. Fill out each section completely; on these forms, Sections 1, 2, and 6 are always required.
Section 1 — Vehicle/Vessel Information (Required)
This section asks the state to identify the exact vehicle you are registering. You enter the Vehicle/Hull Identification Number, the Title Number (if known), and the vehicle’s Year, Make, and Model. Write the VIN in all capital letters and copy it digit by digit straight from the dashboard plate or the existing title.
Format the year as four digits and use the standard make and model spelling, such as 2019, Toyota, Tacoma. If you do not know the title number, leave that blank rather than guessing, since the field is marked “if known.” For example, Maria Lopez enters her VIN 1FTFW1ET5DFA12345, leaves the title number blank, and writes 2013 Ford F-150.
A common edge case is a homemade trailer or a vessel that has a hull number instead of a standard 17-character VIN; in that case you enter the hull or assigned ID number in the same box. The most common mistake here is transposing two digits of the VIN, which links your application to the wrong vehicle record and forces the office to reject it and start over. A frequent misconception is that the make and model alone identify the vehicle — they do not, because the VIN is the only field the state treats as the true identifier.
Section 2 — Title Owner Information (Required)
This section asks who legally owns the vehicle. You enter each Owner – Full Legal Name (First, Middle, Last) or Business Name along with the Idaho Driver’s License Number or SSN/EIN if Business, plus the Owner’s Physical Address, City, State, and Zip + 4. Enter the name exactly as it appears on your Social Security card and Idaho driver’s license, because the state cross-checks it and a mismatch triggers a processing hold.
When there are two owners, you must check either the OR box or the AND box. “OR” lets either owner sign future paperwork alone, while “AND” requires both owners to sign together. For example, James and Karen Webb list both names, enter both driver’s license numbers, and check AND because they want both signatures required.
A key edge case is a name change by marriage or divorce: if your current name differs from the name on the prior title, attach a signed “One and the Same Statement” (the ITD 3125 works) so the records line up. The most common mistake is entering a nickname or shortened name, which creates a mismatch with your license and stalls the title. A widespread misconception is that “OR” and “AND” are interchangeable — they are not, because the choice controls who must sign every future transaction on that vehicle.
Section 3 — Lienholder on Record (If Applicable)
This section asks whether a lender has a financial claim on the vehicle. You enter the Primary Lienholder Name and Mailing Address, and a Secondary Lienholder Name if a second lender exists. Only list a lien that is still active; do not list a loan you have already paid off.
If you list a lienholder here, the state mails the title to that lender at the address you provide, because the lender holds the security interest until the loan is paid. For example, Maria Lopez finances her truck through Idaho Central Credit Union and enters that name and the credit union’s mailing address so the lender receives the title.
The edge case to watch is a recently paid-off loan: if the lien is satisfied, leave this section blank and attach the lien release instead. The most common mistake is listing a paid-off lender out of habit, which sends your title to a bank that no longer has any claim and delays you getting it. A common misconception is that signing this section releases the lien — it does not, because a lienholder’s signature here does not release their interest in the vehicle.
Section 4 — Mail Title to a Different Address
This section lets you route the finished title somewhere other than the owner or lienholder address already on the form. You complete it only when you want the title sent elsewhere, entering the Address, C/O Name, City, State, and Zip + 4. Leave it blank if the title should go to your home address.
The reason this field exists is to handle situations like a snowbird who spends winters out of state or an owner using a trusted agent. For example, George Adler spends winters in Arizona and enters his seasonal address with C/O George Adler so the title does not sit in an empty Idaho mailbox.
The important edge case is a financed vehicle: if a lienholder appears in Section 3, that lienholder must sign Section 6 before the title can be mailed to any Section 4 address. The most common mistake is filling this in while a lien is active without the lender’s signature, which the state will not honor. A common misconception is that this section changes your official address on file — it does not, because address changes require the ITD 3239 or your online DMV account.
Section 5 — Fees Paid
This section totals what you owe and records your payment. You list the Title Fee of $14.00, the County Title Admin Fee (which varies by county), an optional Rush Fee of $26.00, and the Total Fees. If you pay by card, you enter the Credit Card Number, Print Name as shown on front of card, Expiration Date, and Security Code, and you accept that card payments carry service fees.
Do not send cash by mail; if you want to pay cash, you must go in person to a county assessor’s motor vehicle office. For example, Maria Lopez in Blaine County adds the $14.00 title fee to her county’s higher admin fee, which can push title processing toward $32.75, while a filer in Bannock County may pay close to $14.00 total. Look up your exact county admin fee at dmv.idaho.gov before you write the total.
The edge case here is the rush option: pay the extra $26.00 only if you genuinely need expedited handling, since standard processing is fine for most filers. The most common mistake is underpaying the county admin fee, which leaves your total short and stops processing until you send the difference. A common misconception is that the $14.00 is the only fee — it is not, because every county adds its own administrative charge on top.
Section 6 — Owner’s or Lienholder’s Signature With Notary (Required)
This final section makes your application legally binding. You sign on the owner line, provide a Daytime Phone Number, and have the signature notarized or witnessed by a county assessor or deputy assessor. On the duplicate title form, you also check Illegible or Mutilated if those apply and attach the old title.
The signature certifies under penalty of law that everything on the form is true. For example, Maria Lopez signs in front of a notary, who completes the “Subscribed and sworn before me” block with the day and year and applies the seal or stamp. If two owners were joined by “AND” in Section 2, both must sign here; if joined by “OR,” either one may sign.
The edge case is an agent signing for you: attach the original or a verified copy of a notarized power of attorney, or the signature will not count. The most common mistake on these forms is sending them without notarization, and the form states plainly it will NOT be processed unless the signature is notarized. A common misconception is that a lienholder’s signature here releases the lien — it does not, because releasing a lien requires a separate release document.

How to File the Completed Form
Idaho gives you three filing channels, and each works for different needs. Choose the one that matches your situation and keep proof of whatever you submit.
In person at a county office. Bring the completed form, your documents, and payment to your county assessor’s motor vehicle office, such as the DMV Processing Center, PO Box 140019, Garden City ID 83714 for Ada County or the Motor Vehicle Section, 605 N Capital Ave, Idaho Falls ID 83402 for Bonneville County. In person, you can pay by cash, check, or card, and you walk out with your registration the same day. Keep your receipt as proof of filing.
By mail. Mail the form to the county address listed on page two of the title forms, and make your check payable to DMV. Do not send cash by mail. Card payments are accepted but carry service fees, and faxed copies are not accepted. Mailed filings take longer to process, so add the $26.00 rush fee only if you need speed, and keep a copy of everything you send.
Online. For renewals, address changes, and plate orders, log in to your DMV account and pay by card. The portal is the fastest route for renewals and lets you skip the counter entirely. Save the confirmation page or email as your proof of filing. Note that effective July 1, 2026, Idaho eliminated physical registration decals, so officers verify your status electronically and you no longer place a sticker on your plate.
For all channels, the base registration fee depends on the vehicle’s age: $69.00 for vehicles 1–2 years old, $57.00 for 3–6 years, and $45.00 for 7 years or older, plus a county admin fee of $3.00 to $14.00. You can register passenger vehicles for one year or two years at a time.
What Happens After You File
After the office accepts your application, it enters your vehicle into the ITD’s records and issues your registration. If you filed in person, you receive your registration document and plates the same day. If you filed by mail, processing takes longer, and rush service shortens that window for the extra $26.00 fee.
Your title is handled separately from your registration. The state prints and mails the title to you, or to your lienholder if a loan is active, at the address on the form. You can track a title’s status at accessidaho.org if it does not arrive in a reasonable time.
Once registered, your job is to keep coverage current and renew on time. Idaho does not assess an annual vehicle property tax, so there is no separate yearly valuation bill to worry about. There is also no grace period: driving on an expired registration is an infraction, so mark your renewal date and renew through your online account before it lapses.
If you ever lose the paper title, do not refile the whole application. Instead, use the ITD 3367 Duplicate Idaho Title Application, which requires a notarized signature and a $14.00 title fee plus your county admin fee.
Mistakes to Avoid When Filling Out the Form
Each field on this form is its own chance for an error, and each error has a direct cost. Avoid these specific mistakes:
- Transposing VIN digits. A single wrong digit links your filing to the wrong vehicle and forces a full restart.
- Using a nickname instead of your legal name. The name will not match your license, and the state places a hold on the title.
- Skipping notarization in Section 6. The form states it will not be processed without a notarized signature.
- Checking the wrong OR/AND box. The wrong choice can require an extra signature you cannot easily get later.
- Listing a paid-off lienholder. The title gets mailed to a bank with no claim, delaying delivery to you.
- Leaving the lien release out. Without it, the title stays encumbered and cannot be cleared.
- Underpaying the county admin fee. A short payment stops processing until you send the balance.
- Sending cash by mail. The state rejects cash by mail, and your filing goes nowhere.
- Filing the title transfer late. Filing more than 30 days after purchase triggers a $20.00 late penalty.
- Forgetting proof of insurance. Idaho requires coverage from a licensed insurer, and the office will not finish without it.
- Omitting the odometer reading. A missing reading on a newer vehicle voids the required disclosure.
- Using an outdated form version. An old revision can be rejected, so confirm the Rev. date first.
Do’s and Don’ts
These quick rules keep your filing clean and fast.
Do:
- Do get your Idaho driver’s license first, because you cannot register or title a vehicle without it.
- Do copy the VIN exactly, since it is the one field the state treats as the true vehicle identifier.
- Do notarize Section 6, because the form will not process without it.
- Do look up your county admin fee, so your total payment is correct the first time.
- Do keep proof of filing, since it protects you if the application is lost.
- Do file within the deadline, to dodge the $20.00 late title penalty.
Don’t:
- Don’t send cash by mail, because the state will not accept it and your filing stalls.
- Don’t list a paid-off lien, or your title goes to the wrong place.
- Don’t guess the title number, since a wrong number creates a record conflict.
- Don’t use a shortened name, because it must match your license exactly.
- Don’t fax the form, as faxed copies are not accepted.
- Don’t drive on expired tags, since Idaho has no grace period and treats it as an infraction.
Pros and Cons of Filing on Your Own vs. With Help
You can file the application yourself or lean on a dealer, title service, or the county counter staff. Each path has trade-offs.
Pros of filing on your own:
- You save money, because you avoid third-party service fees.
- You control accuracy, since you enter every field yourself.
- You learn the process, which helps with future renewals.
- You move at your own pace, filing online or by mail when convenient.
- You keep your documents in hand, rather than handing them to a middleman.
Cons of filing on your own:
- You carry the risk of errors, and a single mistake causes a hold.
- You must arrange notarization, which adds a step and possible cost.
- You spend the time, gathering documents and visiting the office.
- You may miss county-specific fees, leading to short payments.
- You handle problems alone, if the application is rejected.
County Office vs. Online Filing
The table below compares the two routes most Idaho drivers use.
| Factor | County Office (In Person) | Online DMV Account |
|---|---|---|
| Best for | New titles, transfers, complex cases | Renewals, address changes, plate orders |
| Payment | Cash, check, or card | Card only |
| Speed | Same-day registration | Fastest for renewals |
| Notarization | Staff can witness signatures | Not available |
| Proof to keep | Counter receipt | Confirmation page or email |
FAQs
Do I need an Idaho driver’s license before I register my vehicle?
Yes. New residents must get an Idaho driver’s license or ID card before they can register or title a vehicle, because the state verifies the owner’s name against its license records.
Do I write my full legal name or a nickname in the Owner section?
No. Never use a nickname. Enter your full legal name exactly as it appears on your Idaho driver’s license and Social Security card, or the state places a hold on your title.
Do I check the OR box or the AND box for two owners?
Yes, you must check one. Choose OR if either owner may sign alone, or AND if both owners must sign every future transaction on the vehicle.
Do I list a lienholder I already paid off in Section 3?
No. Leave Section 3 blank for a satisfied loan and attach the lien release, because listing a paid-off lender sends your title to a bank with no claim.
Do I have to notarize the application?
Yes, for title applications like the ITD 3367. The form will not be processed unless your signature is notarized or witnessed by a county assessor or deputy assessor.
Do I need to enter the title number if I do not know it?
No. The title number field is marked “if known,” so leave it blank rather than guessing, since a wrong number creates a conflict in the records.
Do I owe sales tax when I register a vehicle in Idaho?
Yes. A flat 6.0% statewide sales and use tax applies to vehicle purchases, with no extra city or county sales tax added on top.
Do electric vehicles cost more to register?
Yes. Battery electric vehicles pay a $140.00 annual surcharge and plug-in hybrids pay $75.00, both added on top of the base age-based registration fee.
Do I still need a registration sticker on my plate?
No. Effective July 1, 2026, Idaho eliminated physical registration decals, and law enforcement verifies your status through electronic lookup instead.
Do I get charged a penalty for filing late?
Yes. Filing a title transfer more than 30 days after purchase triggers a mandatory $20.00 late title penalty, and Idaho grants no registration grace period.
Do I send cash if I file by mail?
No. Never mail cash. Make your check payable to DMV, or pay by card with service fees, and visit a county office if you want to pay cash.
Do I need the rush fee to get my title?
No. The $26.00 rush fee is optional and only speeds up handling; standard processing works fine for most filers.
Do I use the same form to replace a lost title?
Yes. Use the ITD 3367 Duplicate Idaho Title Application for a lost or destroyed title, but use the ITD 3369 if you also need to transfer ownership.
Do county admin fees vary across Idaho?
Yes. County administrative fees differ, so title processing can run near $14.00 in some counties and up to about $32.75 in others like Blaine County.
