Connecticut antique plates are available for vehicles at least 20 years old that remain unmodified from the manufacturer’s original specifications and are preserved for their historic interest. Registering under this class caps the car’s property tax assessment at $500 no matter what the vehicle is actually worth, exempts it from emissions testing, and puts it on a separate fee schedule. In exchange, the state expects the car to be treated as a collector vehicle rather than a daily driver.
Who Qualifies
Connecticut General Statutes Section 14-1 defines an antique, rare, or special interest motor vehicle as one that is at least 20 years old, preserved because of historic interest, and not altered or modified from the original manufacturer’s specifications.1Connecticut General Assembly. Connecticut Code Chapter 246 – Motor Vehicles All three conditions have to be met. A 25-year-old car driven daily with no attention to preservation fails one leg; a beautifully restored car with a modern engine swap fails another.
The modification standard is where applications most often run into trouble. Restoring a car back to its factory configuration is fine. Adding equipment the car never had from the factory, even period-correct accessories pulled from a different trim level, technically falls outside the statutory definition. In practice the DMV evaluates applications case by case, and the line between restoration and modification is not always obvious. If your vehicle has been changed from its factory build, expect closer scrutiny.
Classic motorcycles qualify under the same rules and have their own fee schedule.2DEPARTMENT OF MOTOR VEHICLES.

The Tax and Emissions Savings
The real payoff of antique registration is the property tax treatment. Connecticut taxes motor vehicles as personal property, and each town applies its local mill rate to the car’s assessed value. A standard registration bases that assessment on retail value, so a collector car worth $80,000 can generate a serious annual bill. Antique-registered vehicles are assessed at exactly $500 by law, regardless of market value.4Connecticut General Assembly. Personal Motor Vehicle Property Tax Assessments and Rates In a town with a 30-mill rate, that works out to $15 a year instead of potentially thousands.
Antique vehicles are also exempt from Connecticut’s emissions testing program, which charges a $20 test fee for standard vehicles. For a car running engine technology that predates modern emissions standards, the exemption avoids both the fee and the risk of trying to pass a test the car was never built for.
How to Apply
Registration starts with Form H-13B, Connecticut’s combined registration and title application. The form asks for the vehicle’s make, model, year, VIN, fuel type, body style, and color.5CT.gov. Connecticut Registration and Title Application H-13B You will need proof of ownership, which is typically the title, or a bill of sale paired with a VIN verification if the car has no Connecticut title.
VIN verifications can be done at a DMV inspection station, by a licensed dealer, or by law enforcement, with the Wethersfield exception for older motorcycles noted above.3DEPARTMENT OF MOTOR VEHICLES. Get a VIN Verification You also need a Connecticut Insurance Identification Card showing at least the state’s minimum liability coverage: $25,000 per person and $50,000 per accident for bodily injury, plus $25,000 for property damage.6Connecticut General Assembly. State Minimum Auto Insurance Requirements
Applications can be submitted in person at a DMV branch or by mail. An in-person visit is worth the time when the vehicle’s history is complicated. Missing titles, out-of-state origins, and unclear modification status all go more smoothly as a conversation than as a paper exchange. Mailed applications missing documents sit until you supply what’s missing, which can add weeks.
What It Costs
For a classic passenger car, SUV, truck, van, bus, or motorhome, the current fees stack as follows:
- Registration fee: $120
- Plate fee: $7
- Administrative fee: $10
- Greenhouse gas fee: $15
- Clean Air Act fee: $15
- Passport to the Parks fee: $24
That totals $191. Classic motorcycles pay a lower $63 base registration plus a $10 greenhouse gas reduction fee and the same surcharges, totaling $129.2DEPARTMENT OF MOTOR VEHICLES. DMV Fees The Passport to the Parks fee rose from $15 to $24 effective July 1, 2025, which reflects an $8-per-year charge built into the registration period.7CT.gov. Passport to the Parks Connecticut’s standard non-commercial registrations run on a three-year cycle, and the $24 Passport math is consistent with that schedule. If you let the registration lapse, a $25 late fee applies.
How You Can Use the Car
Connecticut’s antique plate statute used to spell out that antique-plated vehicles were limited to exhibitions, parades, and similar events. That explicit list is gone from the current law. What remains is the eligibility definition itself: the car must be “preserved because of historic interest.”1Connecticut General Assembly. Connecticut Code Chapter 246 – Motor Vehicles A car driven 15,000 miles a year on errands is hard to describe that way.
The DMV can review and revoke antique registrations. If a usage pattern plainly contradicts preservation, the plates, the tax cap, and the emissions exemption can go with it. The practical rule is to treat the car as a collector vehicle driven to shows, on weekend cruises, and for occasional pleasure, rather than as a commuter.
Insurance Beyond the Minimum
Connecticut requires liability insurance on every registered vehicle, antique plates included. The $25,000/$50,000/$25,000 statutory minimum covers only what you owe other people, not your own car, and that gap matters a lot more when the car is a classic.6Connecticut General Assembly. State Minimum Auto Insurance Requirements
Most classic owners buy physical damage coverage from a specialty collector-vehicle insurer. The important distinction is between agreed-value and actual-cash-value policies. An agreed-value policy pays a negotiated amount if the car is totaled, which reflects true collector value. An actual-cash-value policy pays replacement cost minus depreciation, which on a 40-year-old car can come in shockingly low. Stated-value policies split the difference, but the insurer pays whichever is lower — the stated amount or the actual cash value — so they can surprise you at the wrong moment.
Collector policies typically require that you own a separate daily driver, store the classic in an enclosed structure like a garage or storage unit, and stay within an annual mileage cap, often 3,500 to 7,500 miles. Those conditions line up with how antique-plated cars are expected to be used anyway. Some policies allow seasonal daily use for up to five months, with premiums adjusted to match.
Plate Display
Connecticut issues one plate for antique-registered vehicles, mounted at the rear. The statute requires it to be shown “in a conspicuous place at the rear of such motor vehicle at all times while the vehicle is in use or operation upon any public highway.”8Justia. Connecticut Code 14-20 – Number Plates for Antique, Rare or Special Interest Motor Vehicles The plate has to be clearly visible and unobstructed. A tinted frame, a plate propped in the rear window, or road grime dense enough to obscure the characters can all draw a citation.
Connecticut also allows year-of-manufacture plates on antique vehicles, meaning original-era plates matching the car’s model year. The process requires DMV approval and the plate still has to meet legibility and display standards. Replica or decorative plates are fine for shows and static display but cannot legally replace the DMV-issued plate when the car is on public roads.
Transferring and Replacing Plates
Antique plates stay with you, not the car. When you sell an antique-plated vehicle, you keep the plates and can transfer them to another qualifying vehicle by notifying the DMV.9DEPARTMENT OF MOTOR VEHICLES. Transfer Your License Plate From One Car to Another The buyer applies for their own registration and, if the car qualifies, requests their own antique plates. This is easy to miss in a private sale, so make sure the buyer knows they will need to register the vehicle independently.
If plates are lost, stolen, or damaged, you file Form E-159 at a DMV office.10Department of Motor Vehicles (Connecticut). Form E-159 – Customized Plates and Records Replacement costs $5 with a police report documenting the theft, or $25 without one.11DEPARTMENT OF MOTOR VEHICLES. Replace Your License Plates A case number alone does not substitute for the actual report. The replacement plates will carry a new number.
If the Car Comes From Overseas
Federal import rules sit in front of Connecticut registration for a foreign-market classic. A vehicle that does not comply with U.S. Federal Motor Vehicle Safety Standards generally cannot be permanently imported unless it is at least 25 years old, measured from the month and year of manufacture.12National Highway Traffic Safety Administration (NHTSA). List of Nonconforming Motor Vehicles That Are Eligible for Importation Younger vehicles have to come in through a registered importer and be brought into compliance, which runs into real money.
The 25-year federal threshold overlaps well with Connecticut’s 20-year antique rule. A car old enough to clear federal import is already old enough for antique plates, as long as it still meets the preservation and no-modification criteria. A right-hand-drive 1990s Japanese sports car imported at exactly 25 years clears on age but can raise questions about whether modifications made for U.S. road use, like added reflectors or speedometer conversions, count as alterations from the manufacturer’s original specifications under state law.
If You Sell the Car
A classic car held for personal use is a capital asset. Sell it for more than you paid and the profit is a capital gain, taxed at a maximum federal rate of 28 percent because the IRS treats collectibles separately from the standard 15 or 20 percent long-term rate.13Internal Revenue Service. Topic No. 409, Capital Gains and Losses Classic and antique cars can qualify as collectibles, so a profitable sale may cost more in tax than you’d expect.
The sale is reported on Form 8949 and summarized on Schedule D. A loss on personal-use property is not deductible.14Internal Revenue Service. Publication 544 (2025), Sales and Other Dispositions of Assets Connecticut also taxes capital gains as ordinary income at the state level, so a large sale generates both federal and state liability, and estimated quarterly payments may be needed to avoid an underpayment penalty.
