In accordance with IRS Ruling 2014-32, effective January 1, 2016, you will no longer be permitted to submit mass transit claims for expenses that were paid out of pocket. You can continue to submit claims for parking and vanpool expenses. Vanpool expenses will require a receipt or documentation to verify that the expense is eligible.
Note that at this time, the updated UberX Share and Lyft Share Rides programs no longer meet the IRS requirements for a Commuter Benefit Plan and are no longer eligible expenses.
