How do I correct a motor vehicle fuel tax report that I previously filed?
If you need to change the gallons shown on a report previously filed, send the Department of Revenue a letter detailing the changes. Calculate the additional tax you owe or refund you have coming. Do not file an amended report or reflect the adjustments on your current report. Pay any additional amount owing by EFT, and send your letter detailing the changes to: Wisconsin Department of Revenue Excise Tax Section Mail Stop 5-107 P.O.
