Trucking · IRP registration
IRP apportioned plate fee estimator.
An apportioned (IRP) fee is a share of each jurisdiction’s full-year fee: miles driven there ÷ total fleet miles × that jurisdiction’s fee for your registered weight. The DC DMV’s own example: 25,000 miles in each of four jurisdictions is 25% of each fee, so DC $2,325 becomes $581.25 and the four fees total $1,580.75. You supply the full-year fee for each jurisdiction; this tool does not know them.

IFTA vs IRP: what each one covers
| IFTA | IRP | |
|---|---|---|
| What it is | Agreement to report and pay motor fuel use tax to one base jurisdiction | Agreement to register vehicles once and have registration fees shared between jurisdictions |
| What you pay | Fuel tax, from net taxable gallons by jurisdiction | Registration fees, from your mileage share by jurisdiction |
| How often | Quarterly return (annual by approval) | Annual apportioned registration, renewed with the fleet |
| Tool | IFTA fuel tax calculator | This page |
Both rely on how many miles you drive in each jurisdiction, so keep one set of trip records that serves both. IFTA is defined by the IFTA Articles of Agreement; IRP fee schedules and application rules come from your base jurisdiction.
How the estimate is built
For each jurisdiction: share = miles there ÷ total fleet miles; fee = share × full-year fee for your registered combined gross weight and vehicle type. The DC DMV describes the apportioned fee as “the calculated fee based on the proportion of miles traveled in each jurisdiction” and says licensing fees can only be determined after processing a completed application.
What this estimate leaves out
- Full-year fees. The DC DMV says they depend on the registered combined gross weight and other vehicle criteria; get them from the jurisdiction or your base jurisdiction’s IRP office.
- Partial-year registrations and fleet changes, which your base jurisdiction may handle differently; ask it.
- Title, plate, permit, fuel-tax and other charges that are not apportioned registration fees (the DC DMV page lists only mileage, weight and vehicle criteria as the fee drivers).
Frequently asked questions
How are IRP apportioned fees calculated?
Each jurisdiction’s fee is your miles there divided by total fleet miles, multiplied by that jurisdiction’s full-year fee for your weight. The base jurisdiction collects the total and distributes it.
What is the difference between IFTA and IRP?
IFTA is the fuel use tax agreement: one quarterly return to your base jurisdiction. IRP is the registration agreement: one apportioned plate with fees shared between jurisdictions according to mileage.
Do I need both IFTA and IRP?
Commonly both apply to an interstate qualified motor vehicle, but the thresholds differ by plan and jurisdiction. Check your base jurisdiction’s IRP and IFTA offices.
Why is my actual bill different from this estimate?
This tool uses only the fees and miles you enter. Actual bills depend on the exact weight and fee schedule, other charges, partial-year proration, and the jurisdictions on your application.
Where do I find each jurisdiction’s fee?
From the fee schedules published by each state or province, or the IRP office of your base jurisdiction, which processes the application.
