Frequently Asked Questions
Q1: What is this calculator and how do I use it?
Select your vehicle type, weight class, registration type, fuel source, and ownership status. The calculator instantly displays registration costs for 1-year, 2-year, and 3-year periods.
Q2: Why are there three registration period options?
Connecticut offers three options for different needs: 1-year (lowest cost, frequent renewals), 2-year (balanced, most popular), and 3-year (best value, less frequent renewals).
Q3: What’s the difference between Passenger, Commercial, and Combo registration?
Passenger: Personal use, lowest cost, vehicles under 8,500 lbs. Commercial: Business use, required for trucks over 12,500 lbs. Combo: Dual-purpose for trucks 8,501-12,500 lbs.
Q4: Why can’t I select Passenger registration for my 11,000 lb truck?
Connecticut DMV requires trucks 8,501-12,500 lbs to use Combo or Commercial only. Trucks over 12,500 lbs must use Commercial. The calculator enforces these rules automatically.
Q5: Why is the fee higher for new vehicles?
New vehicles pay $10 greenhouse gas surcharge (vs. $5 for used), plus $40 smog fee, plus $35 title/plate fees—totaling $45-$55 extra per registration cycle.
Q6: Do electric vehicles really cost less to register?
Yes. EVs save $40 (no smog fee) + $10 (no Clean Air fee for 2-year) = $50 per 2-year registration. Example: New EV = $135 vs. New gas car = $185.
Q7: How does weight affect my registration fee?
Passenger autos: Weight does NOT affect base fee ($40/year flat). Trucks & commercial: Weight directly affects fees ($47-$1,546+/year).
Q8: Should I choose 1-year, 2-year, or 3-year registration?
1-year: Lowest cost, unsure ownership. 2-year: Best balance, most popular. 3-year: Best value per year, long-term ownership.

Register in Connecticut if you own a CT business or claim CT residency with vehicle garaged there. Register in your home state if you’re truly a resident of NY, MA, RI, NJ, or PA.
