Delaware IRP Registration and Renewal

Delaware is a popular base jurisdiction because no sales tax means potentially lower operating costs, easy access to major highways like I-95, efficient processing times for IRP applications compared to some larger states. However, remember: you must have a physical place of business in Delaware (not just a P.O. box) to qualify for IRP registration here.

The International Registration Plan (IRP) is an agreement between the 48 continental U.S. states and Canadian provinces that lets commercial trucks legally operate across borders while paying fair taxes based on miles driven in each area. Delaware joined the IRP in 1995, just before Congress required national participation in 1996.

IRP fees help maintain the public highways you drive on every day. The fees you pay are distributed to the states and provinces based on your mileage, so accurate recordkeeping is a must.

Who Needs to Register for Delaware IRP?

Not all commercial vehicles need to register under IRP. You must register if:

Your truck has three or more axles (regardless of weight)
Your truck or combination (truck + trailer + load) exceeds 26,000 pounds gross weight
You travel in more than one IRP jurisdiction

If you stay within Delaware or operate only in exempt situations (like certain government vehicles or farm trucks), IRP registration isn’t required.

What Credentials Will You Get?

When you register for Delaware IRP, you’ll receive:

Apportioned license plate - This tag must be displayed on your power unit and shows that your registration fees are paid.
Cab card - This document lists the jurisdictions you’re authorized for, the registered weights, and important vehicle info. You must carry it in the vehicle at all times.

The IRP isn’t the only requirement for interstate trucking. Most truckers also need IFTA and HVUT (required if your vehicle’s gross weight is 55,000 pounds or more. This is filed using IRS Form 2290.) You’ll also need a valid DOT number, and depending on your routes, trip permits (if you’re waiting for the IRP) or special permits for states that have additional requirements, like New York’s HUT or Oregon’s weight-mile tax.

IRP Renewal in Delaware

IRP credentials must be renewed annually. Delaware sends renewal notices, but it’s the carrier’s responsibility to file the renewal on time. Failing to renew can lead to expired tags, fines, and the inability to operate legally across state lines. It’s a good idea to start the renewal process early, at least 30-60 days before expiration to avoid delays or penalties.

These credentials help law enforcement and DOT officials verify your compliance during roadside inspections.

Important Notes

Keep detailed mileage records for each jurisdiction. Delaware (and other states) can audit your records for up to 3 years. If you occasionally travel out of state without IRP, you can buy individual trip permits.
