You pay tax on the fuel a state says you burned crossing it, and you get credit for the tax already in the fuel you bought there. Buy cheap fuel in a low-rate state and run the miles in a high-rate one and you'll owe the difference — that's most of what a return is.
Rates change every quarter. We update within a day of them posting, and reapply them to any return still open.
