What is a Transportation Reimbursement Plan (TRP)?

A TRP is a pre-tax benefit account used to pay for eligible commuting expenses to/from work. Multnomah County offers two types: Parking TRP and Transit TRP. 

How do TRPs Work? 

  • You contribute money through payroll deductions each pay period for your own work-related parking expenses and/or transit expenses (passes/fares).
  • Your deductions are sent to PacificSource Administrators (PSA) after each pay period.
  • Transit TRP participants can only use the Benny card to access available funds (manual reimbursement requests are not permitted).
  • Parking TRP participants can only submit a reimbursement request with receipts to PSA (Parking TRP funds are not accessible via the Benny card). 
  • Reimbursement claims (for the parking TRP) are processed as soon as the funds are available in your account.
  • Funds remaining in the account at the end of the plan year will roll over to the next plan year
  • You must re-enroll annually (during open enrollment) to keep active participation/payroll deductions in the new plan year. 

Important Facts about TRPs

  • You can make changes (increases/decreases to deductions) to your enrollment as needed (once per month maximum). 
  • You can sign up or cancel your enrollment at any time (not just during open enrollment).
  • Only fund the account for costs you can reasonably predict.
  • If you leave the County (and have enrolled in the Parking TRP), you can only get reimbursed for expenses that you incurred while you were employed (Parking TRP).
  • If you leave the County (and have enrolled in the Transit TRP), any unused funds remaining in the account are forfeited.
