DOT REGISTRATION EXPLAINED

IRP, IFTA, and apportioned plates — they are three different things

New carriers confuse these constantly. Here is what each one actually is, what order to do them in, and where to file.

SHORT ANSWER

What is the difference between IRP, IFTA, and apportioned plates?

IRP (International Registration Plan) is the interstate compact that governs multi-state commercial vehicle registration — it produces your apportioned plates. IFTA (International Fuel Tax Agreement) is a separate agreement that governs fuel-tax reporting for qualified vehicles operating in two or more jurisdictions. Apportioned plates are simply the plates you receive as the output of the IRP process.

You file IRP through your base state to get plates. You get your IFTA license and decals through your base state to report and pay fuel taxes. They are administered by the same agency in most states, but they are separate programs with separate applications and separate ongoing obligations.

How do IRP and IFTA compare?

Side-by-side comparison of both programs.

Feature	IRP (Apportioned Plates)	IFTA (Fuel Tax)
What it is	Interstate compact for apportioning vehicle registration fees across the states you operate in. The result is one set of plates valid in all member jurisdictions.	Interstate agreement for reporting and paying fuel taxes across member jurisdictions. You file one quarterly return with your base state instead of filing in each state separately.
What it governs	Vehicle registration / plates	Fuel tax reporting and payment
When you need it	Operating a qualified commercial vehicle in two or more IRP member jurisdictions	Operating a qualified vehicle in two or more IFTA jurisdictions (see iftach.org for the qualified-vehicle definition).
Who issues it	Your base state motor vehicle agency. File at irp.gov for information; the actual application goes to your state.	Your base state. IFTA license and decals are issued by the same state agency. See iftach.org for base-state contacts.
Ongoing obligation	Annual renewal of your IRP apportioned registration	Quarterly IFTA fuel tax returns to your base state

What order do these steps happen in?

The sequence matters — some steps unlock others. Here is the correct order for a new carrier:

1

Authority goes ACTIVE

Your operating authority must show ACTIVE before you can plate. This requires your BOC-3 (49 CFR §366) and insurance (49 CFR §387) on file — typically about 3–4 weeks (10-day protest + 20-day filing window).

2

File IRS Form 2290 (if vehicle ≥ 55,000 lb)

For vehicles at or above 55,000 lb gross vehicle weight, e-file Form 2290 with the IRS. You receive a stamped Schedule 1, which most states require before they will process your IRP plate registration. E-file at IRS.gov — the stamped Schedule 1 comes back quickly.

3

File for IRP apportioned plates

Apply through your base state's motor vehicle agency. Bring your stamped Schedule 1 (Form 2290) and your FMCSA authority credentials. The output is your apportioned plates — valid in all IRP member jurisdictions.

4

Get your IFTA license and decals

Apply through your base state (usually the same agency that handled IRP). You will receive an IFTA license and two decals for your vehicle. After that, you file quarterly fuel tax returns with your base state.

Frequently asked questions

Are apportioned plates the same as IRP?

Yes — "apportioned plates" is just the common name for what you receive after completing the IRP (International Registration Plan) process through your base state. IRP is the interstate compact that governs multi-state commercial vehicle registration; the plates you get are the output. You file the IRP application through your base state at irp.gov.

Do I need IFTA if I only run in one state?

IFTA (International Fuel Tax Agreement) applies to qualified vehicles operating in two or more IFTA jurisdictions. If you operate exclusively within one state, IFTA may not apply to you — but verify with your state DOT, since some states have their own fuel tax reporting requirements. See the official IFTA guidance at iftach.org for qualified vehicle definitions.

What comes first — IRS Form 2290 or apportioned plates?

Form 2290 comes before plates. For vehicles at or above 55,000 lb gross vehicle weight, you must e-file Form 2290 with the IRS and receive a stamped Schedule 1 before most state motor vehicle agencies will process your IRP apportioned plate registration. The IRS e-file process returns a stamped Schedule 1 quickly — do it at IRS.gov first, then take that document to your base state to register plates.

What is the correct order for all registration steps?

First, wait for your operating authority to go ACTIVE (requires BOC-3 and insurance on file, about 3–4 weeks). Then e-file IRS Form 2290 if your vehicle is 55,000 lb or more. Then file for IRP apportioned plates through your base state. Then apply for your IFTA license and decals through your base state. IFTA quarterly returns follow after that.

While you are handling plates and fuel tax, don't forget the compliance stack

IRP, IFTA, and Form 2290 are the registration side. But before you can legally put a driver in the truck, you also need your drug and alcohol program in place — consortium enrollment, pre-employment test, and Clearinghouse registration. Those requirements exist independently of plates.

We handle the compliance side for you. See the full checklist for every step in order.

Don't let the compliance stack slow you down

While you file your IRP and IFTA, we handle your drug and alcohol program, Clearinghouse queries, and driver qualification files.
