IFTA Tax Rates in Ohio (2026)

Key numbers at a glance

IFTA tax rates in Ohio

Ohio's standard motor fuel tax is $0.3850 per gallon on gasoline and $0.4700 on diesel, the rates set by the 2019 transportation funding increase and carried in the Q4 2026 IFTA rate matrix. The state's own announcement of the 2026 tax holiday confirms the same baseline figures (ohio.gov). Rates below are as of Q4 2026 — confirm the current official IFTA matrix before filing, because Ohio is one jurisdiction whose effective rate this quarter does not match its statute book.

That mismatch is House Bill 519: passed by the legislature and signed in early October 2026, it enacted a 90-day motor fuel tax holiday that cut the state fuel tax from 38.5/47 cents to a nominal 0.01 cent per gallon at the pump. For IFTA purposes the Q4 2026 matrix published by IFTA Inc. still lists Ohio at the standard 38.5/47 cents, and the matrix is not finalized until early December — so carriers owe it to themselves to confirm with their base state exactly how the holiday window is treated on the return before submitting Q4 numbers.

The 8.5-cent diesel premium is structural: the 2019 law raised diesel 19 cents and gasoline 10.5 cents, deliberately loading more of the cost onto heavy trucks. Ohio diesel at 47 cents sits above New York's 38.05 and North Carolina's 41.0, but far below Pennsylvania's 74.1 — which shapes fuel plans for anyone running I-70 or I-80 toward the East Coast.

How Ohio IFTA affects your filings

At the standard 47-cent diesel rate, every 1,000 Ohio miles at 6.5 MPG burns about 153.8 gallons and adds roughly $72.29 to the tax-due column. An Ohio fill pre-pays that same amount per gallon, which is why on a Cleveland-to-Pittsburgh run the smart stop is often Pennsylvania: its 74.1-cent diesel rate credits you 27.1 cents more per gallon than you will owe burning the fuel back in Ohio. Run the exact split with the IFTA calculator before locking a fuel route, and remember the federal 24.4-cent diesel excise never appears anywhere on the return.

The 2026 holiday changes the credit side of Q4. During the 90-day window, diesel bought at Ohio pumps carried almost no Ohio state tax, so those receipts generate little prepaid credit. If your base state follows the matrix and still assesses Ohio miles at 47 cents for the full quarter, you could owe the entire rate on holiday-period Ohio miles with no offsetting credit — precisely the mismatch you want to resolve before the January 31 deadline rather than after a notice arrives. Keep every receipt from the window clearly dated.

Longer term, Ohio is a reminder that IFTA planning is quarterly work: rates that sit still for seven years can move by statute in a week. Update your rate table from the official matrix at the start of every quarter, keep receipts matched to ELD miles, and price your fuel surcharge off after-tax cost, not the sticker at the pump. Every jurisdiction you cross is listed with current figures on the IFTA rates by state hub.
