IR-2020-275, December 9, 2020 WASHINGTON — The Treasury Department and Internal Revenue Service issued final regulations on the deduction for qualified transportation fringe and commuting expenses following changes made by the Tax Cuts and Jobs Act (TCJA). The 2017 TCJA generally disallows deductions for qualified transportation fringe (QTF) expenses and does not allow deductions for certain expenses of transportation and commuting between an employee's residence and place of employment. These final regulations address the disallowance of the deduction for expenses related to QTFs provided to an employee of the taxpayer, including providing guidance and methodologies to determine the amount of QTF parking expenses that is nondeductible. The final regulations also address the disallowance of the deduction for expenses of transportation and commuting between an employee's residence and place of employment. Updates on the implementation of the TCJA can be found on the Tax Reform page of IRS.gov.
