At firms that offer tax-free commuter benefits, the amount of pay you can set aside pretax has increased for 2016. Thinkstock By Kimberly Lankford, Contributing Editor March 25, 2016 How can I get tax-free commuter benefits? Is the money available for parking, or do I need to use it for the subway or bus?If your employer offers commuter benefits, you can set aside up to $255 pretax each month for parking and $255 for mass transportation (such as the train, subway, light rail, bus or ferry) in 2016. If you pay for both parking and mass transit—say, if you drive to a park-and-ride lot and then take a train or subway to work—you can take both benefits, setting aside up to $510 in pretax money each month. Your employer will automatically deduct the money from your pay, and it won’t be subject to income, Social Security or Medicare taxes.

A law signed in December 2015 permanently bumped up the mass-transit limits to match the parking limits, effective retroactively for 2015, and then both benefits were increased to $255 in 2016 to account for inflation.

Your employer may give you a variety of options for receiving the money. WageWorks, which administers benefit plans for employers, gives participants the option to use funds in their transportation account to buy passes directly from more than 650 transit providers around the country or to have the money loaded onto a smart card. It may also issue a debit card that people can use to purchase transit fare with the pretax money, says Dan Neuburger, president of commuter services for WageWorks. The firm’s commuter savings calculator can help you estimate how much money you can save in taxes by participating in the program.
