IRP fee estimator

The apportionment math, from the agencies

Apportioned by mileage: registration fees are pro-rated based on the percentage of highway mileage traveled in each IRP jurisdiction. For example, a fleet running 50 percent of its miles in California and 50 percent in Nevada pays 50 percent of each state's registration fees rather than full fees to both.International Registration Plan (IRP)Verified Jul 18, 2026

Fees are apportioned: each jurisdiction's fee equals the fleet's mileage percentage in that jurisdiction multiplied by that jurisdiction's registration fee schedule for the vehicle's weight. FLHSMV's published example totals 1,121.45 USD for an 80,000 lb unit across its jurisdictions; actual fees vary by fleet mileage distribution and weight.International Registration Plan (IRP)Verified Jul 18, 2026

Registration fees are apportioned: the carrier pays New Mexico a share of each jurisdiction's full registration fee based on the percentage of total fleet miles traveled in that jurisdiction, and New Mexico distributes the other jurisdictions' shares to them. The base jurisdiction may also charge additional fees for issuing credentials or for filing an apportioned-registration application; no member jurisdiction may impose a minimum registration fee on an apportionable vehicle.New Mexico International Registration Plan Manual (Revised January 2019)Verified Jul 20, 2026

Where the fee inputs come from

The percentages are the easy half; the full-year fees come from each jurisdiction's own published schedule for your declared weight. Start from the IRP offices and members reference to find your base jurisdiction's program, and use the state pages for the filing process where this site has them:

• Alabama IRP registration
• California IRP registration
• Colorado IRP registration
• Florida IRP registration
• Georgia IRP registration
• Illinois IRP registration
• Indiana IRP registration
• Kentucky IRP registration
• Louisiana IRP registration
• Michigan IRP registration

Apportioned plates are one line in the same recurring stack as fuel tax: the miles you enter here are the same jurisdiction split the quarterly IFTA calculator works from, and heavy units also owe the annual highway use tax on Form 2290.

Frequently asked questions

How are IRP fees calculated?

Fees are apportioned: each jurisdiction's fee equals the fleet's mileage percentage in that jurisdiction multiplied by that jurisdiction's registration fee schedule for the vehicle's weight. FLHSMV's published example totals 1,121.45 USD for an 80,000 lb unit across its jurisdictions; actual fees vary by fleet mileage distribution and weight.

Why does this tool not show my state’s fee schedule?

Because storing one honestly is not possible at this site’s standard: every member jurisdiction publishes its own schedule, the amounts vary by declared weight, vehicle type, and year, and several states publish them only inside registration systems or PDFs that change without notice. The estimator does the apportionment math and points you at your base jurisdiction’s published schedule for the fee inputs.

How much do apportioned plates cost?

It depends entirely on your weight and your mileage split. The IRP manual illustrates the apportioned calculation as mileage percentage multiplied by each jurisdiction's full fee: for example New Mexico 50 percent of $172.00 equals $86.00, Texas 25 percent of $840.00 equals $210.00, and Arizona 25 percent of $3,957 equals $989.25, for a total registration fee of $1,285.25.

Do I pay each state separately?

Under IRP a carrier files one application with its base jurisdiction instead of registering separately in every jurisdiction. New Mexico issues registration documents for each vehicle; only one license plate and one cab card are issued per commercial vehicle. New accounts, renewals and supplements are handled by the Commercial Vehicle Bureau. The USDOT number of the motor carrier responsible for the safety of each registered vehicle must be identified during registration under the PRISM program, and carriers must complete the biennial update every two years.
