Tax time has arrived. Good news for drivers that expense their fuel, from the Journal of Accountancy :
“TSE expenses [are] deductible as ordinary and necessary trade or business expenses because they [are] analogous to fuel expenses and [are] not…hotel 
expenses. Because Transportation Department regulations require truckers to rest 10 hours for every 14 hours they drive, they must power their trucks for those 10 hours for business reasons. Truckers can either idle their truck engines using diesel fuel or power them by connecting to TSE at truck stops, so the IRS [sees] no distinction between diesel fuel and TSE expenses. The TSE expenses [are] deductible as unreimbursed business expenses subject to the 2% floor on itemized deductions.”
