Starting a Trucking Company in Washington: 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 Washington is the second layer: where you get apportioned plates, who issues your fuel-tax license, whether Washington wants its own registration for trucks that never leave the state, and which state office checks on you. Here is that layer for Washington, checked against the state's own pages in September 2026.
In Washington one office handles both apportioned plates and the IFTA license - the Washington State Department of Licensing. Washington also has its own registration for trucks that haul for hire without leaving the state: the Washington UTC common carrier permit.
Interstate or Washington-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 Washington's job is plates, fuel tax and roadside enforcement. Stay inside Washington and you are an intrastate carrier: no federal authority is needed, and Washington'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 Washington-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 Washington
Washington's IRP office is the Washington State Department of Licensing, Prorate and Fuel Tax Services. To base a fleet in Washington you have to show a real connection to the state: applicants file an Established Place of Business, Residency, or Change of Address form (450004) with the IRP application. Register online through License eXpress for prorate and fuel tax, by mail (PO Box 9048, Olympia, WA 98507-9048) or in person; requires IRP Application 450011, Form 2290, current Washington registrations in the account name and the carrier's USDOT number. Fees are quoted at processing; contact 360-664-1858 or motorcarrierservices@dol.wa.gov.
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 Washington assigns you.
IFTA in Washington
The same office handles IFTA - the Washington State Department of Licensing, Prorate and Fuel Tax Services. IFTA, IRP and fuel tax accounts are managed online through License eXpress (My License Express); quarterly IFTA returns filed with Washington.
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 Washington
If the truck never leaves Washington you do not need federal operating authority (the $300 filing) - but Washington is one of the states that still wants in-state-only trucks to hold a USDOT number. Washington is on FMCSA's intrastate list, and under RCW 46.32.080 the UTC requires common carriers to have a USDOT number when operating vehicles of 16,001+ lbs GVW or hauling hazmat at any weight; household goods, solid waste and bus carriers need one regardless of weight. The number is free, so get it early; almost every state form asks for it.
Washington also has its own registration for hauling other people's freight for hire inside the state: the Washington UTC common carrier permit (intrastate for-hire transportation of property), issued by the Washington Utilities and Transportation Commission (UTC). A common carrier is a company or person that moves property (other than household goods) for pay in Washington State; household goods movers need a separate household goods carrier permit. Complete applications usually process in about one day. Your insurer files a Form E first.
Fee: Paid online with the application (the UTC does not print the amount - Transportation@utc.wa.gov or 360-664-1222). Insurance: $300,000 combined single limit for vehicles under 10,000 lbs; $750,000 CSL over 10,000 lbs; $1,000,000 for hazardous waste; $5,000,000 for bulk hazardous substances/explosives (Form E filed by the insurer).
UCR when you are based in Washington
Washington 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. Carriers that only haul inside the state do not register for UCR at all.
Other Washington permits and programs
Oversize and overweight permits come from the Washington State Department of Transportation, Commercial Vehicle Services - every state wants its own permit for a load beyond the legal size or weight, and most now sell them online.
Other Washington-specific things a new one-truck carrier runs into:
- UTC intrastate insurance requirements: The UTC's table of liability minimums by weight and cargo for permitted carriers ($750,000 combined single limit over 10,000 lbs).
- Washington intrastate USDOT threshold (16,001 lbs): Even if FMCSA's site says no USDOT is needed, Washington law (RCW 46.32.080) requires one for intrastate common carriers over 16,000 lbs GVW or hauling hazmat.
- WSDOT self-issued OS/OW permits: Most routine oversize/overweight permits can be self-issued online 24/7; WSDOT provides a permit fee calculator. Contact CVSpermits@wsdot.wa.gov, 360-704-6340.
Who checks on you in Washington
Roadside inspections in Washington are run by the Washington State Patrol, Commercial Vehicle Enforcement 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 Washington State Department of Licensing (or Washington commercial plates if the truck will never leave the state).
- Get your IFTA license and decals from the Washington State Department of Licensing.
- Register for UCR at ucr.gov if you run interstate.
- If you will haul Washington-only loads, get the Washington UTC common carrier permit before the first one.
- Put the deadlines in the Stay Legal calendar: MCS-150 update, IFTA quarters, UCR, Form 2290, medical card, annual inspection.
Always confirm with Washington
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 Washington pages
Based in Washington? 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 Washington 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.
