3rd Quarter 2026 diesel (“special fuel”) rate for Nebraska.
How Nebraska tax is figured
- 1. Fleet MPG for the quarter = total miles everywhere ÷ total gallons bought everywhere.
- 2. Taxable gallons in Nebraska = miles run in Nebraska ÷ fleet MPG.
- 3. Net gallons = taxable gallons − gallons you actually bought in Nebraska.
- 4. Tax = net gallons × $0.3180.

Common questions
Does the Nebraska rate change every quarter?
It can. IFTA publishes a new tax-rate matrix each quarter, and jurisdictions adjust rates, surcharges and index-linked amounts on their own schedules. The rate above is from IFTA, Inc. Tax Rate Matrix (3Q2026), USD per gallon.
Do I file this return with Nebraska?
No. You file one IFTA return with your base jurisdiction covering every state and province you ran in, and it distributes the money. FuelTaxDesk produces the worksheet you file from — you stay the filer of record.
What if I bought more fuel here than I burned?
Net gallons go negative and the line becomes a credit, which offsets tax owed in other jurisdictions on the same return.
