Wyoming IFTA Filing Walkthrough (Quarterly)

Wyoming keeps IFTA inside its transportation department. The IFTA Section of WYDOT Motor Vehicle Services in Cheyenne issues the license and the decals, takes the quarterly return, and runs apportioned plates out of the same building. The return itself goes through the Commercial Carriers of Wyoming System, CCOWS, the online system WYDOT also uses for IRP work after a first registration. The sourced fees, deadlines and penalty figures render on the Wyoming IFTA page; this walkthrough puts them in the order you will meet them.

Step 1: confirm Wyoming is your base jurisdiction

Your base jurisdiction is where your qualified vehicles are based for registration and where you keep operational control and records, or can make them available. Wyoming asks you to prove that connection before it licenses you, in one of two ways:

• An established place of business: WYDOT's checklist points to an owned or leased physical structure, a lease of at least 12 months, a utility bill and a staffed office.
• Or Wyoming residency: a Wyoming driver license plus at least two other proofs.

A resident agent address, a virtual office, or a service provider's address cannot serve as the location address. That rule matters for carriers who formed a Wyoming LLC through a registered agent and never set up a physical presence in the state.

The qualified vehicle test is the standard IFTA one: two axles with a gross or registered gross weight over 26,000 pounds, three or more axles at any weight, or a combination over 26,000 pounds. Recreational vehicles are excluded.

Step 2: apply on Form CC-105

The application is Form CC-105, Application for Wyoming International Fuel Tax Agreement (IFTA) License, paired with the New IFTA Account Checklist, Form CC-113. Here is what the checklist asks for:

• Proof of a valid EIN. A Social Security number is not accepted, and a sole proprietor needs an EIN too.
• A Wyoming Secretary of State account in good standing for an LLC or corporation.
• An active USDOT number, which WYDOT checks on SAFER.
• The three annual forms: Certification of Established Place of Business or Wyoming Residency, Agreement to Prepare and Maintain Records, and IFTA Safety Regulations.
• Proof of Wyoming registration for every qualified vehicle.

Mail the original signed packet to WyDOT - IFTA, 5300 Bishop Blvd, Cheyenne, WY 82009, or bring it in person. WYDOT prefers mail so it can check the packet for completeness, and it does not process new applications after 3:00 p.m. Same-day service is not guaranteed, so plan the walk-in early.

The fees on CC-105 (Rev 2026-01) are $10 for the license plus $4 per pair of decals, one pair per qualified vehicle, payable to WyDOT. The 2022 IFTA Manual still prints $3 per set, but the current application form governs. No bond is required to get the license. Because the registration proof comes first, most new Wyoming carriers finish their Wyoming IRP registration before the IFTA packet goes in.

Step 3: file each quarter in CCOWS

Wyoming files IFTA returns online through CCOWS at ccows.dot.state.wy.us. WYDOT emails a notice when the system opens for each quarter's filing, giving at least 30 days to file, and the WYDOT IFTA page links CCOWS walkthroughs for filing a return, amending one, and processing a payment.

The due dates follow W.S. 39-17-206(f): the last day of the month after each calendar quarter. On the calendar that means April 30, July 31, October 31 and January 31, moving to the next business day when the date lands on a weekend or legal holiday. Two rules catch new filers:

• A return is due every quarter, even a quarter with no miles.
• A return and its payment count as timely only when both arrive by the due date.

A credit balance works in your favor. WYDOT refunds balances over $100 and asks for detailed records to back any refund over $250. The math of building a return by jurisdiction is the same in every member state; our how to file IFTA guide walks it, and the IFTA calculator runs the per-jurisdiction numbers before you enter them in CCOWS.

Step 4: know what a late or missed quarter costs

A late Wyoming return draws a penalty of $50 or 10 percent of the quarter's net tax, whichever is greater. The penalty applies even when the return shows zero tax or a credit, so a no-miles quarter filed late still costs $50.

Interest runs separately for each jurisdiction, by month or fraction of a month from the due date, at two percentage points above the federal underpayment rate under Internal Revenue Code Section 6621(a)(2), reset each January 1.

Keep missing returns and the license goes. The Wyoming IFTA Manual lists revocation grounds that include unpaid tax, unfiled returns, record-keeping failures, not traveling in more than one jurisdiction, and reporting no base-jurisdiction miles for three quarters. Revocation follows 30 days notice, and a revoked fleet may not operate outside Wyoming. Records supporting each return stay on file for four years from the due date or the filing date, whichever is later, plus the current year, unused decals included.

Step 5: renew by the end of February and place the decals right

The license runs on the calendar year. Wyoming renews the license and decals each year and mails the new license and decals at renewal, with a grace period through the last day of February for the new year's credentials. Extra decals during the year go through the IFTA update form.

Every qualified vehicle carries a copy of the license, even with decals on the cab. One decal goes on the lower rear exterior of the cab on each side, and decals cannot move from one truck to another. A missing license copy or decal can bring a citation or a required fuel trip permit.

The short trip alternative: a fuel trip permit

Not every carrier running through Wyoming needs the license. A carrier without an IFTA license can buy a fuel trip permit at the first port of entry, good for up to 96 hours. W.S. 31-18-201(s) sets the price at $7.50 for a single unit or $15 for a legal combination with one power unit. Every commercial vehicle entering Wyoming stops at a port of entry, so that is where the permit is sold. The registration side has its own 96-hour permit, and both are laid out on the Wyoming trip and fuel permits page.

The Wyoming shape, in short

Four things to remember. The program belongs to WYDOT Motor Vehicle Services, the same office that issues apportioned plates, reachable at 307-777-4827 or [email protected]. The application demands real Wyoming presence, and a registered agent address does not count. Returns file through CCOWS on the standard quarter-end clock, with a $50 floor on late penalties even for zero-tax quarters. And the license and decals renew each year with a grace period to the end of February. Current fuel tax rates by jurisdiction render on the IFTA rates by state table.
