North Dakota IFTA Tax Rate — 2026
Last refreshed from iftach.org on May 14, 2026.
How North Dakota IFTA tax is calculated
For every gallon of diesel your truck "burned" inside North Dakota during the quarter, you owe $0.2300 in IFTA tax. The number of taxable gallons isn't the gallons you bought there — it's the miles you drove inside North Dakota divided by your fleet's average miles-per-gallon for the whole quarter.
Your IFTA return then nets that against the North Dakota fuel-tax you already paid at the pump on gallons purchased inside the state. If you ran more North Dakota miles than you bought North Dakota fuel, you owe the difference. If you bought more North Dakota fuel than you ran North Dakota miles, you get a refund or credit.

Common North Dakota IFTA filing questions
- Do I file IFTA in North Dakota if my home base is here? If your IFTA base jurisdiction is North Dakota, you file your quarterly return with the North Dakota Department of Revenue (or equivalent). Your filing covers every IFTA jurisdiction you ran in, not just North Dakota.
- What if I only drove a few miles through North Dakota? Every IFTA mile counts, even if you only crossed the state. Track them on your trip sheet or ELD report — you'll owe (or get refunded) North Dakota's share whether you bought fuel here or not.
- What if North Dakota fuel is cheaper than the IFTA tax? The IFTA rate above is what you owe per gallon "consumed" in North Dakota. The pump price already includes North Dakota's state fuel tax — that's what gets credited on your return. If you bought all your fuel in a low-tax state and drove all your miles in North Dakota, you'll owe the full North Dakota rate on those gallons at filing time.
