Connecticut registration fees depend on your vehicle's weight and age

Connecticut charges registration fees based on your vehicle's gross vehicle weight rating (GVWR) — the maximum weight it can safely carry — not what it actually weighs. A passenger car typically falls into the 3,500-pound category and costs $120 for a two-year registration. Heavier vehicles, trucks, and vans pay more. The state also charges a $20 registration fee on top of the weight-based fee, plus a $5.50 agent fee if you renew through a DMV agent rather than online.

If your vehicle is brand new and you're registering it for the first time in Connecticut, you'll pay a one-time $50 new vehicle registration fee in addition to the standard fees. Vehicles registered for the first time also require an initial inspection before registration is complete.

Connecticut registration is valid for two years. You renew on the anniversary of your registration date, not on your birthday or a calendar date. The state sends renewal notices by mail about 30 days before your registration expires.

Key Takeaways

  • A standard passenger car registration costs $120 for two years, plus a $20 registration fee and a $5.50 agent fee if you use a DMV agent.
  • Your fee is based on your vehicle's gross vehicle weight rating, so heavier vehicles and trucks pay higher amounts.
  • New vehicle registrations include a one-time $50 fee plus the standard weight-based fee.
  • Connecticut registration lasts two years from your registration date, and the state mails renewal notices about 30 days before expiration.
  • You can renew online, by mail, or through a DMV agent, and online renewal avoids the $5.50 agent fee.

Weight categories and what each costs

Connecticut groups vehicles into weight categories, and each category has its own fee. Passenger cars under 3,500 pounds pay $120 for two years. Vehicles between 3,500 and 5,000 pounds pay $150. Vehicles between 5,000 and 7,500 pounds pay $180. The fees continue to climb for heavier commercial vehicles and trucks.

To find your vehicle's GVWR, check your vehicle's door jamb label, your owner's manual, or your current registration card. The GVWR is not the same as your vehicle's actual weight — it's the maximum safe weight including passengers and cargo. This means a pickup truck might have a GVWR of 6,000 pounds even if it typically weighs less when empty.

If you're unsure which category your vehicle falls into, the Connecticut DMV website has a complete fee schedule by weight class. You can also call your local DMV office or ask a DMV agent when you renew.

How to renew your Connecticut registration

Connecticut offers three renewal methods: online through the DMV website, by mail, or in person at a DMV office or authorized agent. Online renewal is the fastest and cheapest option because it skips the $5.50 agent fee. You'll need your current registration card, your vehicle identification number (VIN), and a valid payment method.

Renewing by mail takes longer — you'll receive a renewal notice in the mail about 30 days before expiration, and you can send it back with your payment. Mail renewal typically takes two to three weeks to process. Renewing in person at a DMV office or through an authorized agent (often insurance agencies or AAA) is when ready, but you'll pay the extra $5.50 agent fee if you use an agent.

Your registration expires at midnight on the last day of your registration period. Driving with an expired registration is illegal in Connecticut, even if you've sent in your renewal payment. If your renewal is delayed, you can print a temporary registration from the DMV website to carry in your vehicle while you wait for your new registration card.

Additional fees and special situations

Connecticut charges extra fees for certain situations beyond the standard registration. If you need a duplicate registration card because yours was lost or damaged, the fee is $20. If you change your vehicle's registration information — such as your address or the vehicle's color — you'll pay a $20 modification fee.

Vehicles registered as commercial or for-hire (like taxis or rideshare vehicles) pay higher registration fees based on their weight class. Disabled veterans and active-duty military members may be may be able to access for registration fee reductions; contact your local DMV office for details about military discounts.

If you register a vehicle that was previously registered out of state, Connecticut treats it as a new registration and charges the $50 new vehicle fee plus the standard weight-based fee. You'll also need to pass an initial inspection before the registration is issued.

When your registration expires and how to check the date

Your registration expires two years from the date it was issued, not from the calendar year. If you registered your vehicle on March 15, 2023, it expires on March 15, 2025. The expiration date appears on your registration card and on your vehicle's registration sticker.

Connecticut registration stickers go on your windshield in the lower right corner (passenger side). The sticker shows your expiration month and year. If you can't find your expiration date, check your registration card or log into your DMV account online to view your registration status.

The state mails renewal notices about 30 days before expiration. If you don't receive a notice, you can still renew online or in person — the notice is a reminder, not a requirement to renew. Renewing early is allowed; you can renew up to 60 days before your current registration expires.

Inspection requirements and registration holds

Connecticut requires all vehicles to pass an emissions inspection before registration can be issued or renewed. The inspection is separate from registration and costs about $30 to $40 depending on your vehicle type. You must have a valid inspection before you can complete your registration renewal.

If your vehicle fails inspection, you cannot register it until repairs are made and it passes. Some repair shops offer free re-inspections after you've had work done, so ask about that when you get repairs. The inspection is valid for one year, so if your registration expires more than a year after your inspection, you'll need a new inspection before you can renew.

If you have unpaid parking tickets, traffic violations, or other outstanding fines with the state, the DMV may place a hold on your registration. You'll need to resolve those issues before you can renew. The DMV will notify you if a hold is in place.

Frequently Asked Questions

Can I renew my Connecticut registration online?

Yes. You can renew online through the Connecticut DMV website if your vehicle has a valid inspection and you have no registration holds. Online renewal takes a few minutes and costs less than renewing through an agent because you avoid the $5.50 agent fee. Your new registration card arrives by mail within one to two weeks.

What if I move to Connecticut from another state?

You have 60 days to register your vehicle in Connecticut after establishing residency. Out-of-state vehicles are treated as new registrations, so you'll pay the $50 new vehicle fee plus the standard weight-based fee. You'll also need a Connecticut inspection before registration is issued.

Do I have to renew my registration in person?

No. Online renewal is available and is usually faster and cheaper. Mail renewal is also an option, though it takes longer. You only need to go in person if you prefer when ready service or if you have a registration hold that requires you to speak with a DMV representative.

What happens if my registration expires while I'm waiting for my renewal?

Driving with an expired registration is illegal. If your renewal is delayed, you can print a temporary registration from the DMV website to carry in your vehicle. The temporary registration is valid for 30 days and covers you while you wait for your new registration card to arrive.

Does Connecticut offer online registration for commercial vehicles?

Commercial and for-hire vehicles can be renewed online, but the process may require additional documentation depending on your vehicle type. Contact the Connecticut DMV or your local DMV office if you're unsure whether your commercial vehicle qualifies for online renewal.
