IFTA Tax Rates by State (2026 Q3)
Every jurisdiction’s official diesel and gasoline IFTA tax rates and surcharge for the current quarter — searchable, sortable, and sourced line-by-line from the IFTA Inc. Tax Matrix.
2026 Q3 IFTA tax rates for every jurisdiction
Truckers once kept handwritten diesel tax cards taped to the dash. This table of IFTA tax rates is that cheat sheet, re-verified against the official source quarterly.
How to read these IFTA tax rates
The IFTA tax rates shown are base figures. Surcharge states (KY, VA) add diesel and gasoline surcharges; Indiana prints one combined diesel rate. A dash means no figure is printed in the matrix.
Filing Calendar & How This Table Stays Current
The sourcing rule, in plain terms
Every row above is read from the IFTA Inc. Tax Matrix — the publication IFTA member jurisdictions report their rates to — and was verified on 2026-09-03 against the matrix’s Q3 2026 (Jul - Sep 2026) view (effective July 1, 2026). Each state’s own agency page is linked in the table as the second source; the five state guides cite filing rules straight from those agencies.
Special programs — like Indiana’s Q3 2026 Gas Tax Holiday split rate — can change the IFTA tax rates mid-quarter. Those changes are announced on IFTA’s Important Notices page and reflected in the state guide the same day we verify.
IFTA Tax Rates — Frequently Asked Questions
The per-gallon fuel tax each IFTA jurisdiction charges on gasoline and diesel. When you file quarterly, the miles driven and gallons burned in each state are taxed at that state’s quarterly rate — these IFTA tax rates are the numbers your return is built from.
Rates change quarterly, taking effect January 1, April 1, July 1 and October 1. These IFTA tax rates reflect Q3 2026, effective July 1, 2026. This page is re-verified each quarter against the Tax Matrix — the July and October cycles usually move the most states.
These IFTA tax rates come from the IFTA Inc. Tax Matrix — the official quarterly rate publication — with each state page on this site also linking that state’s own agency page as a second source. Nothing on this page is estimated.
Fuel taxes are set by each jurisdiction’s legislature or tax agency, and several adjust them automatically with price indices — Washington steps up 1.1 cents on July 1 while Texas holds flat at 20 cents. Those differences make per-state math tedious by hand.
The Tax Matrix flags a few jurisdictions that levy a surcharge on the base rate — the table prints that figure, covering diesel and gasoline for Kentucky and Virginia. Indiana is flagged too but prints one combined special-fuel rate. Add any surcharge to the base for the true cost.
Multiply miles by your fleet MPG to get gallons burned per state, then apply the IFTA tax rates above and subtract tax-paid gallons. The IFTA calculator on this site runs the whole chain live — open it from the links below and keep this table open beside it.
Penalties are jurisdiction-specific: Texas and Washington charge the greater of $50 or 10%, plus interest. Each state rate guide lists that state’s exact rule, and the calculator’s penalty helper estimates the damage before you file.
The Tax Matrix prints no per-gallon rate for Oregon — its row is blank in the official source, so no IFTA tax rates exist to quote. Carriers operating in Oregon should confirm how the state assesses them with Oregon authorities before filing.
