Two structural facts matter to a carrier. First, the variable component: West Virginia recalculates part of its rate against fuel prices, so the 35.7-cent figure is not engraved in stone — the Tax Division publishes motor fuel rates by year, and the IFTA matrix is the place to confirm the current quarter. Second, the exemptions: aviation gasoline, jet fuel, dyed diesel and dyed kerosene are exempt from the 20.5-cent flat portion and pay only the variable rate, per the Tax Division. That matters only off-highway (dyed fuel is never legal for road use), but it explains why you may see different West Virginia figures quoted for different fuels.
Where does 35.7 cents sit? Above the middle of the pack. The same 1,000 miles at 6.5 MPG that cost $54.92 in West Virginia cost $51.69 in Virginia (33.6 cents on diesel), $47.54 in Wisconsin (30.9 cents), $36.92 in Wyoming (24 cents) and $91.54 in Washington (59.5 cents). Tennessee to the south is the region's bargain at 21 cents on diesel. Stack every state at once on the IFTA rates by state hub, and price your own lanes with the IFTA calculator.

How West Virginia IFTA affects your filings
West Virginia miles are expensive miles to climb: grades burn gallons, and gallons carry 35.7 cents each. At 6.5 MPG, budget about 5.5 cents per mile of state fuel tax for I-77's climbs out of the Kanawha Valley — and remember the West Virginia Turnpike's tolls sit entirely outside IFTA; they are a separate line in your cost per mile, not a credit on your fuel tax return.
The filing mechanics are standard. If West Virginia is your base state, the State Tax Division administers your IFTA account and quarterly return, and it offers refund and exemption provisions against the flat and variable components for qualifying uses. If you are passing through, your job is accurate per-state miles and receipts that match them — auditors typically request four consecutive quarters, and distance records that do not reconcile to fuel purchases are the most common finding. Deadlines never move, and zero-net quarters still get filed:
| Quarter | Period | Deadline |
|---|---|---|
| Q1 | Jan 1 – Mar 31 | April 30 |
| Q2 | Apr 1 – Jun 30 | July 31 |
| Q3 | Jul 1 – Sep 30 | October 31 |
| Q4 | Oct 1 – Dec 31 | January 31 (next year) |
Fuel strategy on West Virginia lanes: the state's 35.7 cents beats neighboring Virginia's 33.6 on diesel by only 2.1 cents, so cross-border fueling between the two is close to a wash — shop the net pump price instead. The bigger wins come from fueling in West Virginia before long runs into Tennessee (21 cents) or from topping off in low-tax states before entering, depending on which side of the credit you want to sit on. Whatever you choose, accrue the tax in your running costs and make sure your fuel surcharge is recovering it — verify current rates at the West Virginia Tax Division or the IFTA Inc. matrix before each filing.
