IRP Registration CT

If you operate a commercial truck across state lines, staying compliant with registration and fuel tax regulations is essential. This guide breaks down the key requirements for IRP registration, trip permits, IFTA licensing, and renewals in Connecticut - everything you need to know as a new or seasoned interstate carrier.

Connecticut participates in both the International Registration Plan (IRP) and the International Fuel Tax Agreement (IFTA). Whether you’re registering a fleet or just one vehicle, understanding these programs is the first step toward legal and efficient operations.

Do You Need IRP in Connecticut?

IRP (International Registration Plan) is an agreement among the U.S. states and Canadian provinces that allows commercial carriers to operate across jurisdictions using a single license plate and cab card. Connecticut is an IRP member jurisdiction.

You must register for IRP in Connecticut if your vehicle:

Has a gross vehicle weight (GVW) of 26,000 lbs or more, or
Has three or more axles, regardless of weight, and
Operates in two or more IRP jurisdictions.

IRP fees are calculated and distributed based on the miles you travel in each jurisdiction, so accurate recordkeeping is crucial. Simply put, IRP is for those who operate across state lines and travel long distances.

How to Register for IRP in Connecticut

To register under IRP in Connecticut, you'll need to start by creating an IRP account with the Connecticut Department of Motor Vehicles (DMV).

Required Documents:

USDOT Number
Proof of Connecticut residency or business address
Vehicle title or lease agreement
Proof of insurance
Form 2290 (Heavy Vehicle Use Tax)
Odometer reading or prior mileage records (or an estimate for new fleets)

Once your application is processed and fees are paid, you'll receive apportioned license plates and a cab card listing all jurisdictions you're registered to operate in.

What About the Trip Permits?

If your vehicle is not IRP-registered and you need to travel through Connecticut or another IRP member jurisdiction temporarily, you’ll need a trip permit instead.

A Connecticut trip permit allows you to operate legally for a short period - typically 72 hours - without full IRP registration. This is ideal for:

Out-of-state carriers making a one-time delivery
New vehicles not yet added to your IRP fleet

Trip permits can be obtained online or through third-party providers (like us!).

IFTA in Connecticut - Who Needs to Register?

The International Fuel Tax Agreement (IFTA) simplifies fuel tax reporting for interstate motor carriers. Instead of filing separate tax reports in each state you drive through, you file one consolidated report.

You need to register for IFTA in Connecticut if your vehicle:

Has three or more axles, or
Has a GVW of 26,000 lbs or more, and
Travels in two or more IFTA jurisdictions

To apply, register with the Connecticut Department of Revenue Services (DRS). You’ll need a valid USDOT number, a CT tax registration number, business and vehicle information. Once approved, you'll receive an IFTA license and a set of two decals, which must be placed on both sides of your power unit. Do not forget that IFTA requires quarterly fuel tax reporting, so track your mileage and fuel purchases carefully.

IRP Renewal in Connecticut

IRP registration in Connecticut must be renewed annually. Your cab card will show the expiration date, and it’s important to renew before that to avoid penalties or being placed out of service. You’ll need to have updated mileage for the reporting period, proof of insurance, form 2209 and your vehicle documents.

The DMV typically sends out renewal reminders, but it’s your responsibility to submit everything on time.

IFTA Renewal in Connecticut

Your IFTA license and decals are valid for one calendar year. Renewal typically opens in November or December, and all outstanding quarterly fuel tax reports must be filed before your renewal is approved.

Make sure to apply early - operating without valid decals in January can result in fines or enforcement actions.
