What form you need and where to get it

Connecticut uses Form H-20 to register a vehicle or renew an existing registration. You can get this form three ways: read it from the Connecticut DMV website (ct.gov/dmv), pick up a copy at any DMV branch office, or request it by mail from the DMV.

The form itself is straightforward — it's a single page that asks for your vehicle information, your personal details, and what type of registration you're seeking. Whether you're registering a new vehicle, renewing an expired registration, or transferring a title, you'll use the same H-20 form, though the documents you bring with it will differ.

You can submit the completed form in person at a DMV office, by mail to the Connecticut DMV, or online through the DMV's website if you're renewing a registration. Online renewal is the fastest route if you're may be able to access — most people renewing a current registration can do it without visiting an office.

Key Takeaways

  • Form H-20 is Connecticut's single registration form for new registrations, renewals, and title transfers.
  • You'll need your vehicle's VIN, current title or registration, proof of insurance, and a completed H-20 form to register or renew.
  • Online renewal through the DMV website is available for most current registrations and takes minutes.
  • If you're registering a new vehicle or transferring a title, you must submit the form in person or by mail with supporting documents.
  • Connecticut requires proof of insurance before the DMV will process any registration or renewal.

What information goes on the form

Form H-20 asks for your name, address, phone number, and driver's license number in the owner information section. If there's a co-owner, you'll fill in their details in a separate area. Make sure the address matches what's on your driver's license — the DMV will flag mismatches and may delay processing.

The vehicle section requires your Vehicle Identification Number (VIN), which you'll find on your title, registration, or on the dashboard at the base of the windshield on the driver's side. You'll also enter the vehicle's year, make, model, and body type. If you're renewing, this information should already be on your current registration card.

You'll indicate whether this is a new registration, a renewal, a transfer, or a duplicate. Check only one box. If you're unsure which category applies to your situation, the DMV website has a quick reference guide, or you can call the DMV at 860-263-5700 before submitting.

Documents you must submit with the form

Every registration or renewal requires proof of Connecticut auto insurance. Bring your insurance card or a letter from your insurer showing your policy number, coverage dates, and the vehicle's VIN. The insurance must be active on the date you submit the form.

For a new vehicle registration, you'll also need the manufacturer's certificate of origin or the title from the previous owner. If you're transferring a title from another state, bring that title plus any lien release documents if the vehicle has a loan. For a renewal, you'll need your current registration card.

Bring a form of identification — your driver's license, passport, or state ID. If you're registering a vehicle in someone else's name or as a business, bring documentation showing your authority to do so, such as a power of attorney or corporate resolution.

How to submit the form in person or by mail

If you're submitting in person, visit any Connecticut DMV office during business hours. Bring the completed H-20 form, your insurance proof, your title or current registration, and your ID. The DMV will process most registrations and renewals while you wait, though you may need to return for your new registration card if the office is busy.

To submit by mail, send the completed H-20 form along with copies of your insurance proof, title or registration, and a check or money order for the registration fee to the Connecticut DMV. Mail processing typically takes two to three weeks. Include a return address so the DMV can send your new registration card back to you.

The DMV's mailing address is on the form itself. Do not send cash through the mail. If you're paying by check, make it payable to "State of Connecticut." Keep a copy of everything you send for your records.

Online renewal if you're may be able to access

If your registration is current and not expired, you can renew online through the Connecticut DMV website without filling out a paper form. You'll need your registration number, VIN, and a valid insurance policy. The online system will verify your information and process the renewal in minutes.

Online renewal is not available if your registration has expired, if you're registering a new vehicle, or if you're transferring a title. You also cannot renew online if there are outstanding violations or fines on your account. If the online system tells you that you're not may be able to access, you'll need to use the paper form and submit it in person or by mail.

After you complete an online renewal, the DMV will email you a confirmation. Your new registration card will arrive by mail within one to two weeks.

Registration fees and what affects the cost

Connecticut registration fees vary based on the vehicle's weight and whether it's a passenger car, truck, or motorcycle. A passenger car typically costs between $100 and $150 for a two-year registration, but the exact amount depends on the vehicle's gross vehicle weight rating (GVWR). The H-20 form includes a fee schedule, or you can look up your vehicle's fee on the DMV website before you submit.

If you're registering a new vehicle, you'll pay the full two-year fee. If you're renewing, you'll pay for another two years from your current expiration date. Some vehicles may have access to for reduced fees — electric vehicles, for example, may have lower registration costs in Connecticut.

The DMV accepts checks, money orders, and credit cards (in person or online). If you're paying by mail, include the fee with your form. If you're unsure of the exact amount, call the DMV or check the fee schedule on the website before sending payment.

What happens after you submit the form

If you submit in person, the DMV will review your form and documents on the spot. If everything is complete and correct, you'll receive your new registration card before you leave. If something is missing or incorrect, the DMV will tell you what you need to fix.

If you submit by mail, the DMV will process your form within two to three weeks. They'll send your new registration card to the address you provided on the form. If there's a problem with your submission, the DMV will mail you a notice asking for additional information or documents. Respond promptly to avoid delays.

Your registration card is valid for two years from the date of issue. The expiration date will be printed on the card. You'll need to renew before that date to keep your registration current.

Frequently Asked Questions

Can I register a vehicle if I don't have a Connecticut driver's license?

Yes. You need a valid form of ID — a passport, state ID, or out-of-state driver's license will work. However, if you live in Connecticut, the DMV may require you to get a Connecticut ID or license before completing the registration.

What if I make a mistake on the form after I submit it?

If you submitted in person, ask the DMV staff to correct it before you leave. If you submitted by mail and notice an error, contact the DMV when ready at 860-263-5700. They may be able to correct minor errors without requiring you to resubmit the entire form.

Do I need to notarize the H-20 form?

No. Connecticut does not require notarization of the H-20 form for standard registrations or renewals. However, if you're registering a vehicle in a business name or using a power of attorney, the DMV may ask for notarized documents — call ahead to confirm what's needed.

How long is my registration valid?

Connecticut registrations are valid for two years from the date of issue. Your expiration date will be printed on your registration card. You can renew up to 30 days before expiration without penalty.

What if my vehicle's title is from another state?

Bring the out-of-state title along with the completed H-20 form. The DMV will process the title transfer and issue a Connecticut title and registration. This typically takes longer than a standard renewal — allow four to six weeks if submitting by mail.
