New Hampshire's Department of Safety registers apportioned trucks at two DMV offices, Concord and Twin Mountain, and through the Motor Carrier Connect portal. Registrations are staggered by month, continuous registration applies and there is no grace period. Fees are each jurisdiction's fee multiplied by the fleet's share of miles there. A New Hampshire resident still needs the town or city registration permit first, because an IRP registration does not exempt the local permit fee.
New Hampshire IRP administration
- Office
- IRP registrations are processed at the DMV Concord Registration Bureau, 23 Hazen Drive, Concord, NH 03305, and at DMV Twin Mountain IRP, 549 Route 302 West, Twin Mountain, NH 03595.
- Process
- New accounts file Schedules A/E and B; changes to an existing account use Schedule C, and adding jurisdictions mid-year uses Schedule F. The forms are available at the Concord and Twin Mountain DMV offices, and registrations can be processed by mail. Proof of the federal Heavy Vehicle Use Tax (Form 2290) is required at registration for vehicles of 55,000 pounds or more, except for a vehicle registered within 60 days of the bill of sale.
- Fee structure
- Fees depend on the vehicle's weight and the jurisdictions traveled: each jurisdiction's registration fee is multiplied by the fleet's percentage of miles in that jurisdiction. IRP, Inc. publishes New Hampshire's fee schedule as a spreadsheet on the jurisdiction profile.
- Fees: other fees
- An IRP registration does not exempt a New Hampshire resident from the town or city registration permit fee required by RSA 261:148.
- Cab card
- Apportioned vehicles receive one set of license plates and one cab card from the base jurisdiction. New Hampshire's maximum cab card weight is 80,000 pounds; weight above that runs on an overweight permit with no change to the cab card.
To work through your mileage inputs, calculate each jurisdiction’s share of your fleet miles. The estimator apportions any full-year fees you enter; it does not contain state fee schedules or issue an official quote.
More New Hampshire IRP rules
- Temporary credentials: hunters permit
- An unladen vehicle (Hunter's) permit, registered for no more than the empty weight and valid in all member jurisdictions, is $20 for 20 days.

Base jurisdiction, renewal, and audit in detail
The rules that decide whether New Hampshire can be your base jurisdiction, what qualifies, and what happens at renewal and audit. Each one is sourced.
- Base jurisdiction rules: Summary
- Under IRP Section 305, New Hampshire can be the base jurisdiction if the applicant has an established place of business here, the fleet accrues distance here and the fleet's records are kept or made available here. An applicant with no established place of business anywhere may base where it can show residence with at least three listed proofs, such as a driver's license, state incorporation, tax filings, utility bills or a vehicle titled in the state.
- Qualifying vehicles: Scope
- A vehicle conducting commercial business that leaves New Hampshire for other jurisdictions is apportionable if it is a power unit with two axles and a gross vehicle weight over 26,000 pounds, a power unit with three or more axles regardless of weight, or used in a combination over 26,000 pounds.
- Qualifying vehicles: Trip permits
- A trip permit is issued in lieu of IRP credentials to a vehicle properly registered in its base jurisdiction but not apportioned for New Hampshire, and must be obtained before entry.
- Renewal: Summary
- Staggered monthly registration periods, with continuous registration required and no grace period. A registrant who returns unused credentials to 23 Hazen Drive within 90 days of issuance may apply in writing for a refund, and credit for a vehicle permanently removed from service may be applied to a newly acquired vehicle.
What the New Hampshire share of the fee is built from
An IRP bill is the base jurisdiction's own registration fee for the vehicle, apportioned by mileage, plus the same for every other jurisdiction on the cab card. These are the New Hampshire inputs to that calculation, each with its official source.
Which trucks need IRP plates
A commercial vehicle that leaves New Hampshire for other jurisdictions is apportionable if it is a two-axle power unit over the IRP weight line, a power unit with three or more axles at any weight, or used in a combination over that line. Each apportioned truck gets one set of plates and one cab card from New Hampshire.
Applying
New accounts file Schedules A/E and B. Changes to an existing account use Schedule C, and adding jurisdictions mid-year uses Schedule F. The forms are at the Concord and Twin Mountain offices, and registrations can be done by mail or through Motor Carrier Connect. Heavy trucks need proof of the federal heavy vehicle use tax unless the truck was bought recently.
A New Hampshire resident must first get the registration permit from the town or city where they live. IRP does not replace that permit or its fee.
Making New Hampshire your base
New Hampshire can be your base jurisdiction if you have an established place of business here, your fleet runs miles here, and its records are kept or available here. Without an established place of business anywhere, you may base where you can show residence with the listed proofs.
Renewal, refunds and credits
Registration periods are staggered by month, continuous registration is required, and there is no grace period. Unused credentials returned to Concord within a set window after issue can qualify for a refund on written request, and credit for a truck taken out of service can move to a newly bought one. The cab card weight tops out at the state maximum; heavier loads run on an overweight permit.
Reach the New Hampshire IRP office
Account problems, supplement filings and credential replacements all route through the office that holds the account. Everything below is the agency's own published channel; where it publishes no phone line, the note says so rather than pointing at a permit vendor's number.

What pairs with IRP
The same interstate operation that needs apportioned plates almost always needs an IFTA license through New Hampshire, and heavy power units owe the federal Form 2290 heavy vehicle use tax before plates renew. To compare how other states run IRP, see the national IRP registration table.
