Estimated Total (3-Year Registration)

Base Registration$120.00
Ad Valorem Tax$476.88

Calculations are estimates. Connecticut registrations are typically valid for three years -- the total shown is a 3-year figure, not annual. Local motor vehicle property taxes are billed annually and separately by your town (not part of this 3-year DMV total) and must be paid to avoid a DMV compliance hold. Connecticut Rev Stat 12-71e caps every town's motor vehicle mill rate at 32.46 mills as of FY 2022-23 -- towns that previously charged more (Hartford and Waterbury charged 74+ mills before the cap) are now legally limited to this ceiling.

County millage rates shown below are county-wide averages for illustration. Actual rates vary by city and school district within a county — confirm your exact rate with your local License Commissioner or Revenue Commissioner before budgeting an exact amount.

Penalty Note: Connecticut charges a $10 late fee applied to your registration if you renew more than five days after the expiration date (assessed on day 6). Additionally, if you owe delinquent town property taxes or unpaid parking tickets, the DMV will place a 'compliance issue' block on your account, preventing you from renewing. Note that there is also a separate $20 late fee if you miss your scheduled emissions testing. Residents 65 and older may opt for a 1-year registration at a prorated fee instead of the standard 3-year term.

Insider Hacks

Verified Connecticut DMV Tips

🎯 Registration Hack

The 'Compliance Block': Connecticut towns report unpaid property taxes and parking tickets directly to the DMV. Always check the online 'Compliance Issues' portal before attempting to renew your registration. If your town hasn't cleared your property tax record, you'll be turned away at the DMV.

⚠️ Tax Warning

No Local Sales Tax, But High Property Tax: Connecticut does not allow cities to charge local auto sales tax. However, the state assesses a hefty annual motor vehicle property tax based on 70% of your car's clean retail value, multiplied by your town's specific mill rate -- now capped at 32.46 mills statewide, but still substantial in high-mill towns.

Frequently Asked Questions

How much are Connecticut vehicle registration fees?
The base fee for a standard passenger vehicle is $120 for a three-year registration. However, you must also pay a $7 plate fee, a $10 admin fee, a $15 Clean Air Act fee, a $15 Greenhouse Gas fee, and a $24 Passport to the Parks fee. This brings the total standard DMV fees to $191 before title fees and taxes.
What is the Connecticut Luxury Vehicle Tax?
Connecticut has a flat statewide sales tax of 6.35% with no local sales taxes. However, if you purchase a motor vehicle with a sales price exceeding $50,000, the state applies a 'Luxury Tax' rate of 7.75% to the entire purchase amount, not just the amount above $50,000.
Why is there a 'Compliance Hold' on my CT vehicle registration?
In Connecticut, the DMV is directly linked to town tax collectors. If you owe delinquent motor vehicle property taxes, unpaid parking tickets, or have suspended emissions, the DMV places a compliance hold on your account, which blocks you from renewing your tags.
What is the Passport to the Parks fee?
This is a mandatory fee added to all non-commercial vehicle registrations. Effective July 2025, the fee increased to $24 for a three-year registration ($8 per year). It allows vehicles with CT plates to park for free at all state parks and beaches.
Is there a cap on how much property tax my town can charge on my car?
Yes. Connecticut Rev Stat 12-71e caps every town's motor vehicle mill rate at 32.46 mills statewide, effective since FY 2022-23. Before this cap, some towns (like Hartford and Waterbury) charged upwards of 74 mills -- an effective rate over 5% of a vehicle's assessed value. If your town's rate was historically high, you're now protected by this statewide ceiling.
