Diesel prices are averages and may vary by location. IFTA tax rates are for Q1 2026 (effective January 1, 2026). IFTA Adjusted Price = Average Diesel Price − IFTA Tax Rate. This tool is for informational purposes only.
Why IFTA Adjusted Prices Matter
The pump price you pay for diesel includes your state's fuel tax. But under IFTA, you don't actually keep the tax with the state where you fuel — it gets redistributed based on the miles you drive in each state.
The IFTA Adjusted Price removes the tax component, showing you the true base cost of fuel in each state. This is the number that actually affects your bottom line when deciding where to fuel up.
For example, a state with high pump prices but high IFTA tax rates might actually be cheaper to fuel in than a state with low pump prices but low tax rates — because you'll get more of that tax money back through IFTA credits.
