Connecticut is one of the few states that does not charge battery-electric or plug-in hybrid owners an extra annual road-use surcharge. A passenger EV, PHEV, hybrid, or gasoline car all pay the same base registration fee: $120 every three years, or about $40 per year. That changed in 2022 when Connecticut repealed a former EV discount that had reduced registration to $57 per three-year period. Today EV owners actually save $15 over three years compared with most gasoline cars because electric vehicles are exempt from the Clean Air Act fee. New vehicles of all fuel types pay a $15 greenhouse gas reduction fee and a Passport to the Parks surcharge that rose to $24 on July 1, 2025. First-time registration also includes a $25 title fee, $5 plate fee, and $10 administrative fee. Purchase costs add Connecticut sales tax at 6.35% on the first $50,000 of price and 7.75% on amounts above that threshold, plus annual property tax assessed by your town. State CHEAPR rebates can return $1,000 to $5,000 at purchase, and Eversource or United Illuminating customers may earn $120 to $300 per year for off-peak charging plus up to $1,000 toward a home Level 2 charger. This guide explains every DMV fee, tax, incentive, and calculation step in plain language so you can estimate the true cost of registering and owning an EV in Connecticut in 2026.

Many states now impose dedicated EV surcharges ranging from $100 to $250 per year to replace lost gasoline tax revenue. Oregon charges battery-electric owners roughly $188 per year. Tennessee assesses $200. Connecticut deliberately chose a different path: equal base registration for all passenger vehicles regardless of fuel type.

That does not mean EV ownership is free of government fees. Connecticut still collects environmental surcharges, title and plate fees, sales tax on purchase, and property tax every year through your municipality. Understanding which fees apply to EVs and which do not helps you compare Connecticut fairly against neighboring states and budget accurately for a new or used electric vehicle.

For a typical three-year registration cycle, a new battery-electric passenger car might pay about $199 in DMV fees at first registration versus about $214 for a comparable new gasoline car, because the EV skips the $15 Clean Air Act charge. Over a decade of ownership, that $15 savings repeats at each new registration cycle for the gasoline car but never applies to the EV.

Total cost of ownership also depends heavily on CHEAPR rebates, utility charging credits, and Connecticut’s relatively high electricity rates. Registration fees are a small line item compared with sales tax on a $45,000 vehicle or annual property tax in towns like Greenwich or Hartford.

Base Registration Fees (CGS §14-49)

Connecticut General Statutes Section 14-49 sets registration fees by vehicle class. For standard passenger automobiles used for personal transportation, the fee is $120 for a three-year registration period, regardless of whether the vehicle runs on gasoline, diesel, hybrid, plug-in hybrid, or battery-electric power.

Senior citizens age 65 or older may elect a one-year registration at approximately $40 per year instead of the three-year term. Combination vehicles used partly for commercial passenger service (such as livery or taxi) pay $132 for three years plus $4 per seat beyond seven. Motorcycles register at $63 for three years or $21 per year.

Important: A 2022 Connecticut law repealed the former reduced EV registration rate of $57 per three years. Battery-electric and plug-in hybrid vehicles now pay the full $120 like every other passenger car.

Passenger vehicle registration summary

Vehicle class3-year feeImplied annual
Passenger car (all fuel types)$120$40
Passenger car (senior 1-year option)~$40$40
Passenger combination (livery/taxi)$132 + seatsVaries
Motorcycle$63$21
Light trailer (≤ 3,000 lb GVWR)$28.50$9.50
Farm vehicle (eligible)$45$15

Pickups and SUVs with a gross vehicle weight rating of 8,550 pounds or less may register as passenger vehicles if not used commercially. Heavier commercial trucks use weight-based fees under CGS Section 14-47 instead of the flat passenger rate.

Example 1: New BEV Three-Year Registration

Scenario: 2026 Tesla Model 3, personal use, standard three-year term.

Base registration (3-year): $120.00 Implied annual equivalent: $40.00

Same base fee as any other passenger car in Connecticut.

Example 2: PHEV vs. Gasoline Sedan (Base Fee Only)

2026 Toyota RAV4 Prime (PHEV): $120 / 3 yrs 2026 Honda Accord (gasoline): $120 / 3 yrs Base registration difference: $0.00

DMV Surcharges and Standard Fees

Beyond the base registration fee, Connecticut collects several standard DMV charges and environmental surcharges at registration. Amounts below reflect 2026 rates.

Complete fee table (passenger vehicles)

Fee typeAmountApplies to EV?Notes
Plate fee$5YesNew or replacement plates
Administrative fee$10YesEvery new registration or renewal
Title fee$25YesOne-time at first title
Lien recording fee$10If financedWhen lienholder on title
Clean Air Act fee$15NoEVs and trailers exempt
Greenhouse Gas Reduction fee$15Yes (if new)New vehicles with CT certificate of origin

The Clean Air Act fee typically equals about $5 per year over the three-year registration period, billed as $15 total. Electric vehicles and electric trailers are explicitly exempt. The greenhouse gas reduction fee applies to all new vehicles sold with a Connecticut certificate of origin, including battery-electric models.

Example 1: New BEV First Registration (2026, No Lien)

Base registration (3-year): $120.00 Plate fee: $5.00 Administrative fee: $10.00 Title fee: $25.00 Clean Air Act fee: $0.00 (EV exempt) Greenhouse Gas fee: $15.00 (new vehicle) Passport to the Parks: $24.00 Lien fee: $0.00 Transfer fee: $0.00 ────────────────────────────────────────── Total DMV fees (3-year period): $199.00 Annual equivalent: ~$66.33

Example 2: New Gasoline Car (Same Terms, for Comparison)

Base registration: $120.00 Plate, admin, title: $40.00 Clean Air Act fee: $15.00 (gas pays; EV does not) Greenhouse Gas fee: $15.00 Passport to the Parks: $24.00 ────────────────────────────────────────── Total DMV fees: $214.00 EV savings on DMV fees: $15.00 per 3-year cycle

Example 3: Three-Year Renewal (Used EV, No Re-Title)

Base registration: $120.00 Plate (if replacement needed): $5.00 Administrative fee: $10.00 Greenhouse Gas fee: $0.00 (used vehicle) Passport to the Parks: $24.00 ────────────────────────────────────────── Renewal total: $159.00 (~$53/yr; no title or GH fee on renewal)

How EVs, PHEVs, and Hybrids Are Treated Differently

Under Connecticut law, an electric vehicle includes battery-electric vehicles, fuel-cell electric vehicles, plug-in hybrids, and range-extended battery-electric designs. A plug-in hybrid can charge from the grid while parked. A conventional hybrid uses both electric motor and combustion engine but cannot plug in for grid charging.

For registration purposes, all three types pay the same $120 base fee. The meaningful difference is the Clean Air Act exemption: battery-electric vehicles and trailers skip the $15 charge. Plug-in hybrids and conventional hybrids do not qualify for that exemption because they still burn fuel and participate in emissions programs differently.

Fee comparison by fuel type (new passenger car, 2026)

Fuel type3-yr DMV totalvs. BEV
Battery-electric (BEV)$199—
Plug-in hybrid (PHEV)$214+$15
Conventional hybrid (HEV)$214+$15
Gasoline$214+$15

Connecticut does not operate a separate EV road-use tax, mileage fee, or annual battery surcharge as of 2026. Commercial electric trucks over 8,550 pounds GVWR follow weight-based registration under CGS Section 14-47 rather than the passenger flat rate.

Sales Tax and Property Tax

DMV registration fees are separate from purchase taxes. Connecticut imposes a statewide sales and use tax on motor vehicle purchases.

Sales tax rates

  • 6.35% on the purchase price up to $50,000
  • 7.75% on any portion of the purchase price above $50,000 (luxury surcharge)

Private party sales between individuals may follow different rules; dealer sales always trigger tax. Trade-in credit treatment should be confirmed with the Department of Revenue Services for your specific transaction.

Vehicle property tax

Connecticut towns assess an annual property tax on motor vehicles. The state caps the mill rate at 32.46 mills for the motor vehicle component in many contexts. Assessment typically uses 70% of fair market value multiplied by the local mill rate. Effective rates often fall in the range of 1.5% to 2.5% of depreciated vehicle value depending on municipality. Property tax is collected by your town, not the DMV.

Example 1: $45,000 New EV Sales Tax

Purchase price: $45,000.00 All below $50,000 threshold Sales tax (6.35%): $2,857.50

Example 2: $65,000 EV Sales Tax (Luxury Portion)

First $50,000 × 6.35%: $3,175.00 Next $15,000 × 7.75%: $1,162.50 Total sales tax: $4,337.50

Example 3: Estimated Property Tax (Illustrative)

Scenario: Year-one vehicle worth $40,000, town mill rate near cap, 70% assessment ratio.

Assessed value: 70% × $40,000 = $28,000 Tax at 32.46 mills: $28,000 × 0.03246 = $909/yr (Actual mill rates vary by town; use local assessor data)

CHEAPR Rebates, Federal Credits, and Utility Programs

Connecticut CHEAPR program (DEEP)

The Connecticut Hydrogen and Electric Automobile Purchase Rebate (CHEAPR) program provides point-of-sale or post-purchase rebates for qualifying clean vehicles. Amounts depend on vehicle type, battery size, and household income.

Program tierTypical rebateEligibility
Standard CHEAPR — new BEVUp to $2,000General income; battery requirements apply
Standard CHEAPR — new PHEVUp to $1,500General income; battery ≥ 10 kWh typical
Rebate+ (income-qualified) — new BEVUp to $5,000Environmental justice / income caps
Rebate+ — new PHEVUp to $3,000Income-qualified buyers
Used EV/PHEV rebatesVariesWhen program funding permits

A $1,000 standard rebate is common on many new battery-electric purchases when higher tiers do not apply. Dealers often apply CHEAPR at the point of sale when funding is available.

Federal tax credits (2026 status)

  • New Clean Vehicle Credit (IRC §30D): up to $7,500 — generally unavailable for vehicles acquired after September 30, 2025
  • Used Clean Vehicle Credit (IRC §25E): up to $4,000 for qualifying used EV purchases
  • Home charger credit (IRC §30C): 30% up to $1,000 through June 30, 2026 for qualifying residential equipment

Utility EV programs (Eversource and United Illuminating)

PURA-approved programs offer managed charging credits of roughly $120 to $300 per year for charging primarily during off-peak hours. Home Level 2 charger rebates reach up to $1,000 for residential customers and higher amounts for commercial installations. Select your utility in a cost calculator to show the correct incentive stack.

Example 1: $45,000 Model 3 With Standard CHEAPR

DMV fees (from earlier example): $199.00 Sales tax (6.35%): $2,857.50 Subtotal before rebates: $3,056.50 CHEAPR rebate: -$1,000.00 ────────────────────────────────────────── Net registration + tax (est.): $2,056.50 (excludes vehicle purchase price and property tax)

Example 2: Income-Qualified Rebate+ Buyer

Purchase price: $38,000.00 Sales tax + DMV: ~$2,610.00 CHEAPR Rebate+ (BEV): -$5,000.00 Utility charger rebate: -$1,000.00 Managed charging credit: -$120/yr (ongoing) ────────────────────────────────────────── Effective year-one offset: ~$6,120+ in incentives

Electricity Rates and Charging Costs

Connecticut residential electricity rates rank among the highest in the continental United States, often exceeding 20 cents per kilowatt-hour. Eversource and United Illuminating serve most of the state. Off-peak managed charging programs materially reduce effective cost per mile.

Energy cost from MPGe:

kWh per mile = 33.7 ÷ MPGe Annual grid kWh = annual miles × kWh per mile ÷ charging efficiency (~90%) Annual cost = grid kWh × $/kWh

Example 1: BEV at 12,000 mi/yr, 120 MPGe, 22¢/kWh

kWh per mile: 33.7 ÷ 120 = 0.281 kWh/mi Grid kWh: 12,000 × 0.281 ÷ 0.90 = 3,747 kWh Annual cost: 3,747 × $0.22 = $824/yr

Example 2: Managed Off-Peak vs. Gasoline

Off-peak effective rate (~14¢): ~$525/yr Gas sedan (30 MPG, $3.50/gal): $1,400/yr Annual fuel savings: ~$875/yr Minus higher CT electricity baseline vs. national avg

Utility credits of $120 to $300 per year further improve the EV economics picture.

How the Connecticut EV Fee Calculator Works

A Connecticut total cost calculator combines DMV registration fees, purchase sales tax, optional property tax, rebates, and operating costs.

Step-by-step logic

  1. Classify the vehicle: passenger, commercial, motorcycle, trailer; personal vs. commercial use.
  2. Determine base registration: $120 for standard passenger (3-year); weight-based if commercial over 8,550 lb GVWR.
  3. Add standard DMV fees: plate $5, admin $10, title $25 (if new), lien $10 (if financed).
  4. Apply surcharges: skip Clean Air Act if BEV; add GH $15 if new; add Passport $24; add transfer $21 if moving in; add late $25 if applicable.
  5. Compute sales tax: 6.35% up to $50,000 plus 7.75% on excess.
  6. Estimate property tax: 70% of value × local mill rate (user selects town).
  7. Subtract CHEAPR and utility rebates from purchase-side costs.
  8. Add annual energy costs using utility rate and MPGe.

Common Questions

Do EVs pay extra registration fees in Connecticut?

No. Connecticut does not impose a dedicated EV surcharge. Battery-electric, plug-in hybrid, hybrid, and gasoline passenger cars all pay the same $120 base fee every three years.

Do EVs pay less than gasoline cars on any DMV fees?

Yes. Electric vehicles are exempt from the $15 Clean Air Act fee that applies to most gasoline and hybrid registrations, saving $15 per three-year cycle.

What changed in 2022 for EV registration?

Connecticut repealed a discounted $57 three-year rate for electric vehicles. EVs now pay the full $120 like other passenger cars.

How much are total DMV fees for a new EV in 2026?

Expect roughly $199 for a standard three-year first registration including title, plate, admin, greenhouse gas, and Passport fees, before sales tax.

Is there Connecticut sales tax on EVs?

Yes. Dealer purchases are taxed at 6.35% up to $50,000 and 7.75% on any amount above that threshold.

What is CHEAPR?

Connecticut’s DEEP-administered rebate program offering roughly $1,000 to $5,000 off qualifying new battery-electric or plug-in hybrid purchases depending on income tier.

Do I pay property tax on my EV?

Yes. Connecticut towns assess annual property tax on registered motor vehicles based on depreciated value and local mill rates.

Edge Cases and Exemptions

Government and transit vehicles: Exempt from registration fees under CGS Section 14-49(o).

Disabled veterans: Limited exemptions may apply; confirm with DMV.

Antique and classic plates: Vehicles 20 years or older may qualify for special registration; classic plate fees differ from standard passenger rates.

Commercial trucks over 8,550 lb GVWR: Weight-based fees under CGS Section 14-47 replace the flat passenger rate.

Leased vehicles: Leasing company typically holds title; registration responsibility follows lease contract terms.

Out-of-state transfers: Add $21 registration transfer fee when moving a vehicle into Connecticut.

Farm vehicles: Eligible farm registrations pay $45 per three years under CGS Section 14-49(q) with qualifying farm income documentation.

Where the Numbers Come From

Registration fee amounts come from CGS Section 14-49 and Connecticut DMV published fee schedules updated through July 2026. Environmental surcharges follow DEEP and DMV guidance. CHEAPR rebate levels come from Connecticut DEEP program documentation. Utility incentive amounts come from PURA-approved Eversource and United Illuminating filings. Sales tax rates follow Connecticut Department of Revenue Services publications. Property tax methodology follows state assessment statutes and municipal assessor practices.

Key Takeaways for Connecticut EV Owners

Connecticut treats electric vehicles fairly on registration: no dedicated EV surcharge and the same $120 per three-year base fee as gasoline cars. EV owners save the $15 Clean Air Act fee that hybrids and gas vehicles pay. New registrations add title, greenhouse gas, and Passport surcharges totaling about $199 in DMV fees for a typical new BEV versus $214 for a new gasoline car.

Purchase costs dominate the picture: 6.35% sales tax on most EV prices and annual property tax through your town. Offset those with CHEAPR rebates of $1,000 to $5,000 and utility programs offering $120 to $300 per year in managed charging credits plus up to $1,000 for home charger installation.

Compared with states charging $150 to $250 per year in EV-specific fees, Connecticut registration remains relatively modest. Budget for sales tax, property tax, and electricity — not just the DMV line items. Confirm current CHEAPR funding and fee schedules with Connecticut DMV and DEEP before you buy.

Disclaimer: This guide is for education and estimation only. Connecticut fees, CHEAPR funding, tax rates, and utility program rules change. Verify all amounts with Connecticut DMV, DEEP, DRS, and your municipality before completing a transaction.
