IRP registration: who needs apportioned plates and how it works
Updated
A power unit used in two or more IRP member jurisdictions generally needs apportioned registration if it has three or more axles or weighs over 26,000 lb, alone or in combination. You register through your base jurisdiction, which issues an apportioned plate and a cab card. Fees depend on each jurisdiction's schedule and the distance you run.

Which trucks need IRP
To qualify for apportioned registration, a power unit has to run, or be meant to run, in two or more member jurisdictions. It must carry passengers for hire or mainly haul property, and it has to meet one of the tests below.
- Two axles and a gross or registered weight over 26,000 lb
- Three or more axles, at any weight
- A combination with a gross weight over 26,000 lb
Recreational vehicles, restricted-plate vehicles and government vehicles are excluded. A lighter truck that otherwise fits can register under IRP by choice.
For a small fleet, a hotshot pickup qualifies once the pickup and trailer together go over 26,000 lb. A two-axle box truck that stays at 26,000 lb or under and pulls no trailer doesn't need apportioned plates.
What you get and what it costs
Your base jurisdiction handles the registration and issues the apportioned plate and cab card. It also sets the paperwork, the renewal date and any trip permit options.
The fee is apportioned, with no single national IRP fee. What you pay depends on each member jurisdiction's fee schedule and the distance you run in each one.
In Texas, the December 2025 IRP packet figures the fee as each jurisdiction's full fee times your share of distance there, plus any nonapportioned charges. A new fleet with no distance history uses published average distances.
Texas-based carriers register through the Texas Department of Motor Vehicles. See Texas IRP for the state's process.
Before you register
Gather the distance records for each jurisdiction you run in, since your fees are based on them. Ask your base jurisdiction what it needs for a first registration and when your plates renew, because those rules are set state by state.
How IRP differs from IFTA and UCR
- IRP covers registration and plates, with apportioned fees paid through your base jurisdiction.
- IFTA is the fuel tax side. Its axle and weight test is similar, and you file a return every quarter.
- UCR is a yearly federal registration fee by fleet size, and IRP-plated trucks have to be counted for it.
When you add a truck, check it against both, since the IRP and IFTA vehicle tests line up closely. IFTA has its own license and decals.

Frequently asked questions
Does a box truck need IRP plates?
Only when it runs in two or more member jurisdictions and passes one of three tests: three or more axles, two axles with a gross or registered weight over 26,000 lb or a combination gross weight over 26,000 lb with a trailer. A lighter truck can still register under IRP by choice.
Is IRP the same as IFTA?
No. IRP is your registration and plates, and IFTA is your fuel tax license and quarterly returns. Both go through your base jurisdiction, and you can need both for the same truck.
Is there one national IRP fee?
No. Each jurisdiction's schedule and your distance set the fee, and your base jurisdiction sets your renewal date.
