Trucking permits are required to collect taxes from interstate truckers for fuel and miles operated over the highways of the United States. Each state typically has different tax rates on fuel purchased and miles driven. Regarding tax reporting, states use fuel and mileage tax reporting to ensure they are getting their fair share of the tax money that the truckers are paying. Miles operated in each state are calculated and taxes paid accordingly. Truckers need to be sure this reporting is done right to avoid costly audits. Additionally, this program can help you find the best locations to purchase your fuel.
