Free Connecticut ATV Bill of Sale

In Connecticut, ATVs and snowmobiles are titled and registered through the Department of Energy and Environmental Protection (CT DEEP), not the DMV. A bill of sale documents the transfer of ownership, supports the buyer's 6.35% sales tax payment, and is submitted with the DEEP Snowmobile/ATV Application. ATVs cannot be operated on public roads or highways in Connecticut (except to cross), and riders under 18 must complete a state-approved safety course. Insurance is recommended though not state-mandated.

Connecticut Requirements: Transfer title within 30 days. 6.35% sales tax.

ATV titling laws are inconsistent — some states require full title transfers, others only require registration, and a few have no requirements at all. Read our guide to find out exactly what your state requires for off-road vehicle transfers. Read: Do I Need a Bill of Sale?

Connecticut ATV Sale — Step-by-Step Checklist

  1. Complete a written bill of sale with full VIN, year/make/model, engine displacement, price and date
  2. Have the seller sign over the existing CT DEEP title (or out-of-state title)
  3. Submit the CT DEEP Snowmobile/All-Terrain Vehicle Application with title, bill of sale and fee
  4. Pay 6.35% CT sales/use tax to DEEP at registration
  5. Riders under 18 complete a CT DEEP-approved ATV safety course
  6. Verify you have legal land to ride — no public-road operation; private land requires owner permission
  7. Consider liability insurance even though not state-mandated

Common Pitfalls

  • Trying to register an ATV at DMV — Connecticut routes ATVs and snowmobiles through DEEP
  • Riding on public roads, which is prohibited except for direct crossings
  • Skipping the safety course for under-18 riders, which is a state requirement
  • Buying an ATV with no title — CT requires a title for transfer; missing-title cases need a bonded process
  • Assuming farm/utility use is automatically tax-exempt without a CT Farmer Tax Exemption Permit
  • Operating on state forest land or trails not designated for ATVs — most CT state lands are off-limits

Pro Tip

Register your ATV with CT DEEP (not DMV), pay 6.35% sales tax, and complete the youth safety course if required. Remember Connecticut prohibits public-road operation — line up legal land before you buy.

Connecticut ATV Bill of Sale — FAQs

Where do I register an ATV in Connecticut — DMV or DEEP?
CT DEEP, not the DMV. Connecticut routes ATV and snowmobile titling and registration through the Department of Energy and Environmental Protection. You submit the Snowmobile/All-Terrain Vehicle Application along with the assigned title, your bill of sale, and the registration fee. DEEP also collects the 6.35% sales/use tax. Registration must be renewed annually. Trying to register an ATV at the DMV will send you back across town to DEEP, so go straight to the right agency.
Can I ride an ATV on the road in Connecticut?
No. Connecticut prohibits ATVs on public roads, highways, and most state-owned land. The only exception is direct crossing of a public road at a perpendicular angle when going from one trail or property to another, after coming to a complete stop. Most riding happens on private land with the owner's written permission or at designated club facilities. Connecticut has very limited public ATV trail access compared to surrounding states. Always carry proof of registration and landowner permission.
Do youth riders need a safety course in Connecticut?
Yes. Riders under 18 must complete a CT DEEP-approved ATV safety course before operating an ATV on land other than land owned by their parent or guardian. Courses are offered by the ATV Safety Institute and other DEEP-recognized providers, typically taking a half-day and covering riding fundamentals, environmental ethics, and safety equipment. The completion card should be carried while riding. Adults are not required to take the course but are strongly encouraged to.
How much sales tax do I pay on an ATV purchase in CT?
Connecticut's standard 6.35% sales/use tax applies to ATV purchases, calculated on the actual sale price (DEEP may use book value if the declared price seems unreasonably low). Tax is paid to CT DEEP at registration, not to the seller in a private sale. Family transfers between qualifying relatives are exempt with Form CERT-106, and farmers holding a CT Farmer Tax Exemption Permit can purchase qualifying utility ATVs tax-free for agricultural use using Form CERT-115.
What information should be on my CT ATV bill of sale?
Include the full VIN, year, make, model and engine displacement of the ATV; the buyer's and seller's full legal names, addresses and phone numbers; the sale price and payment terms; the date of sale; an "as-is" statement (or any agreed warranty); and signatures of both parties (notarization is not required). Attach a copy of the previous CT DEEP title with the assignment section completed. DEEP will use the bill of sale to assess sales tax and issue the new title and registration.
