Montana vehicle registration renews every two years on your birthday month, and you can renew by mail, online, or in person at your county's motor vehicle office.
Montana ties registration renewal to your birthday, so your renewal month depends on when you were born. You'll receive a renewal notice in the mail about 30 days before your registration expires. The notice includes your renewal fee, which varies based on your vehicle's age and type. You have three ways to renew: mail the completed notice with payment, use the online system at the Montana Department of Justice website, or visit your county motor vehicle office in person.
The process itself is straightforward if you have the renewal notice. If you've moved and didn't receive it, you can still renew using your vehicle identification number (VIN) and driver's license number. The key is not to let your registration lapse — driving with an expired registration can result in a citation, even if you've already paid for the renewal.

Renewing Online Through the Montana Department of Justice
The online renewal system is the fastest option if you have your renewal notice or your vehicle's VIN and driver's license number. Go to the Montana Department of Justice website and select the vehicle registration renewal option. You'll enter your vehicle information and pay the renewal fee using a credit or debit card. The system accepts Visa, Mastercard, American Express, and Discover.
After you complete the online renewal, you'll receive a confirmation email with a temporary registration document. Print this confirmation and keep it in your vehicle until your new registration sticker arrives by mail, which typically takes 5 to 10 business days. The temporary document is not a valid registration sticker, but it shows law enforcement that you've renewed if you're stopped before the physical sticker arrives.
Renewing by Mail With Your Renewal Notice
If you prefer to renew by mail, use the renewal notice you received from the state. Fill out the notice completely, including any changes to your address or vehicle information. Attach a check or money order for the renewal fee — do not send cash through the mail. Mail the completed notice to the address printed on the form, which is typically your county motor vehicle office.
Mail renewal takes longer than online renewal because of postal delivery time. Plan for 2 to 3 weeks from the time you mail the form until your new sticker arrives. If your registration expires before the sticker reaches you, you're still protected if you can show the renewal notice or a mailed receipt. Keep documentation of when you mailed the form in case you're stopped during the processing period.
Renewing in Person at Your County Motor Vehicle Office
You can walk into any Montana county motor vehicle office and renew your registration on the spot. Bring your renewal notice, driver's license, and proof of insurance. If you don't have your renewal notice, bring your vehicle's VIN and your driver's license. The office will process your renewal when ready, and you'll leave with your new registration sticker.
In-person renewal is the best option if your registration has already expired or is expiring within a few days. You'll also avoid any mail delays. County offices are typically open during standard business hours, Monday through Friday. Some larger offices may have extended hours or Saturday appointments, so check your county's website for specific times before you go.
What Happens if You Miss Your Renewal Date
If your registration expires before you renew, you can still renew using any of the three methods above. However, driving with an expired registration is a violation, and you can receive a citation even if you've already paid for the renewal online or by mail. The citation is separate from the renewal fee.
If you're cited for an expired registration, you can show the officer your renewal confirmation email or the mailed receipt as proof that you've renewed. This may help reduce the fine or result in the citation being dismissed, but it depends on the officer and the specific circumstances. The safest approach is to renew before your current registration expires, or to renew online when ready if you realize it has lapsed.
Understanding Your Renewal Fee
Montana calculates registration fees based on your vehicle's age, weight, and type. A newer vehicle typically costs more to register than an older one. Trucks and commercial vehicles may have different fee structures than passenger cars. The renewal notice you receive will show your specific fee, so you'll know the exact amount before you renew.
If you believe your fee is incorrect, contact your county motor vehicle office before you pay. They can review your vehicle's registration history and confirm whether the amount is right. Fees can change year to year based on state law, so your renewal fee may be different from last time even if your vehicle hasn't changed.
If You Don't Receive a Renewal Notice
If you haven't received a renewal notice 30 days before your registration expires, contact your county motor vehicle office directly. They can confirm your renewal date and resend the notice if needed. If you've recently moved, the notice may have gone to your old address — update your address with the motor vehicle office as soon as possible.
You don't need to wait for the renewal notice to renew. You can renew online or in person using your VIN and driver's license number. This is especially useful if you're close to your expiration date and don't want to wait for the mail. The online system will show you your renewal fee and allow you to complete the process when ready.
Frequently Asked Questions
What do I do if my registration sticker doesn't arrive after I renew online?
Contact the Montana Department of Justice if your sticker doesn't arrive within 15 business days of your online renewal. Keep your confirmation email as proof of renewal. You can drive with the temporary registration document you printed until the physical sticker arrives or until you contact the state to request a replacement.
Can I renew my registration if my vehicle has a lien on it?
Yes, you can renew your registration regardless of whether there's a lien. The lien holder does not need to approve the renewal. Bring your renewal notice or VIN and driver's license to renew online, by mail, or in person.
What if I sell my vehicle before my registration expires?
You should notify the Montana Department of Justice that you've sold the vehicle so you're not responsible for any violations or fees after the sale. You can do this online or by contacting your county motor vehicle office. Your registration does not transfer to the new owner — they must register the vehicle in their name.
Do I need proof of insurance to renew my registration?
If you renew in person, bring proof of current insurance. If you renew online or by mail, you're not required to show proof at the time of renewal, but Montana law requires you to carry insurance while driving. Make sure your policy is active before you renew.
Can someone else renew my registration for me?
Yes, another person can renew your registration by mail or in person if they have your renewal notice or your VIN and driver's license number. They'll need to sign the renewal form or provide your authorization. Online renewal requires your personal information, so you would need to complete that yourself or provide your login credentials.
