Starting a Trucking Company in Idaho: The State-Level Steps
Updated September 2026
Your USDOT number and operating authority come from FMCSA and work the same in every state. What changes when you are based in Idaho is the second layer: where you get apportioned plates, who issues your fuel-tax license, whether Idaho wants its own registration for trucks that never leave the state, and which state office checks on you. Here is that layer for Idaho, checked against the state's own pages in September 2026.
In Idaho apportioned plates come from the Idaho Transportation Department while the IFTA license comes from the Idaho State Tax Commission. There is no separate Idaho operating authority for general freight - the state layer is plates, fuel tax, the USDOT number and permits.
Interstate or Idaho-only? Decide this first
Two different rulebooks apply depending on where the truck goes. Cross a state line for pay and you are an interstate carrier: FMCSA issues your USDOT number and operating authority (the $300 filing) and sets the insurance and BOC-3 rules, and Idaho's job is plates, fuel tax and roadside enforcement. Stay inside Idaho and you are an intrastate carrier: no federal authority is needed, and Idaho's own rules take over - covered in the in-state section below.
Most new owner-operators run interstate, so this page assumes that unless it says otherwise. If you are truly Idaho-only, you register the truck and its fuel with the state instead of IRP and IFTA, and the in-state section is the one to read closely.
Apportioned plates (IRP) in Idaho
Idaho's IRP office is the Idaho Transportation Department, DMV Commercial Vehicle Services (CVS). To base a fleet in Idaho you have to show a real connection to the state: established place of business: a physical structure in Idaho owned, leased or rented by the registrant, open and staffed during regular business hours by the registrant's employees for trucking-related business; or Idaho residency shown by at least three documents (Idaho driver's license, personal vehicle registration, tax filings, property tax assessment, utility bill, lease or mortgage statement). CVS contact cvs@itd.idaho.gov, (208) 872-3163; online account access through the Idaho enterprise registration site (crs.idaho.celtic-host.com/IDEnterprise) and the Idaho Trucking Portal; USDOT numbers on the account must be in good standing or the account is suspended. Commercial vehicles over 60,000 lbs must register through CVS; 8,001-26,000 lbs may use CVS or the county assessor. No flat fee shown.
Bring what every IRP office wants: your USDOT number and EIN, the truck's title or lease, proof of insurance, and a stamped Form 2290 Schedule 1 if the truck is 55,000 lbs or heavier. Fees are split among the states by the share of miles you run in each, so nobody can quote a flat price up front - the states that publish an estimate put a first-year 80,000 lb plate at roughly $1,250 to $2,500. You renew every year in the month Idaho assigns you.
IFTA in Idaho
IFTA lives at a different agency: the Idaho State Tax Commission. License and decal fee: $10 processing fee plus $0.60 per set of two decals (two sets required per vehicle). Apply online through TAP (tax.idaho.gov/gotoTAP), by mail with Form IMC-2, or by fax/email with phone payment through the IFTA Help Desk; license valid January through December; decals go on both sides of the lower rear of the cab.
Once licensed you file a quarterly return - due April 30, July 31, October 31 and January 31 - even for a quarter with zero miles. Keep every fuel receipt and your miles by state; the return is built from them. The license expires December 31 and is renewed every year.
Hauling only inside Idaho
If the truck never leaves Idaho you do not need federal operating authority (the $300 filing) - but Idaho is one of the states that still wants in-state-only trucks to hold a USDOT number. ITD's Trucker's Handbook says the USDOT number applies to interstate trucks over 10,000 lbs and intrastate trucks over 26,000 lbs, with the Idaho State Police Commercial Vehicle Safety office (208-884-7220) handling intrastate numbers; Idaho is also on FMCSA's list. The number is free, so get it early; almost every state form asks for it.
Idaho has no state operating authority for general freight - ITD's publications treat operating authority as a purely federal matter. An Idaho-only truck registers under the Full Fee program through Commercial Vehicle Services (or the county assessor between 8,001 and 26,000 lbs) and gets a USDOT number above 26,000 lbs.
UCR when you are based in Idaho
Idaho takes part in the Unified Carrier Registration program. Interstate carriers register once a year at ucr.gov - $46 for 0-2 trucks in 2026, $55 in 2027. ITD publishes a UCR fact sheet. Carriers that only haul inside the state do not register for UCR at all.
Other Idaho permits and programs
Oversize and overweight permits come from the Idaho Transportation Department, Special Permits Office (800-662-7133) - permits4idaho.com / Idaho Trucking Online - every state wants its own permit for a load beyond the legal size or weight, and most now sell them online.
Other Idaho-specific things a new one-truck carrier runs into:
- Special permits through permits4idaho.com: Single-trip and annual oversize/overweight special permits are ordered online at permits4idaho.com or by phone at 800-662-7133.
- ISP new entrant audits and medical certificate out-of-service rule: ISP CVS conducts the new entrant safety audits for Idaho-based carriers and notes that since April 1, 2025 a driver without a valid medical certificate is placed out of service.
Who checks on you in Idaho
Roadside inspections in Idaho are run by the Idaho State Police, Commercial Vehicle Safety (CVS) Division, working with FMCSA. Expect the New Entrant safety audit within your first 12 months of interstate operation - the walkthrough's audit checklist covers the 16 things that fail it automatically.
The order to do it in
- Form the business and get a free EIN from the IRS.
- Get your USDOT number (free) through FMCSA's Motus system - and apply for operating authority ($300) if you will ever cross a state line.
- Have your insurer file the federal proof of insurance and hire a process agent for the BOC-3.
- File Form 2290 with the IRS if the truck is 55,000 lbs or heavier and keep the stamped Schedule 1 - the plate office asks for it.
- Get apportioned plates from the Idaho Transportation Department (or Idaho commercial plates if the truck will never leave the state).
- Get your IFTA license and decals from the Idaho State Tax Commission.
- Register for UCR at ucr.gov if you run interstate.
- Put the deadlines in the Stay Legal calendar: MCS-150 update, IFTA quarters, UCR, Form 2290, medical card, annual inspection.
Always confirm with Idaho
Fees and forms move without notice. Before you pay anyone, open the official pages below and check the current figures - it takes ten minutes and prevents expensive surprises. HaulLegal is not the government, is not a law firm, and never files anything for you; you do every step yourself.
Official Idaho pages
Based in Idaho? The walkthrough puts all of this in order.
The HaulLegal walkthrough lays out every step from the business filing to your first safety audit, federal and state, with the real government fee beside each one - and the Stay Legal calendar turns your USDOT number and dates into a deadline list that emails you before each one. The first four steps are free, no signup.
One thing every Idaho carrier needs no matter which state they are based in: a self-employed CDL driver has to be in a drug and alcohol random testing pool run by a consortium before the first mile, and having no program and no random pool are two of the sixteen automatic failures on the New Entrant safety audit.
