Qualified transportation fringe benefits are a popular way for employers to support commuting costs while offering tax advantages. But what happens to unused balances when an employee leaves the company? If you’re considering implementing a qualified transportation plan, it’s crucial to understand the IRS rules governing these benefits—especially regarding terminations.

Key IRS Rules for Transportation Plans

Two primary IRS rules shape how balances are treated upon termination:

  1. No-Former-Employees Rule
    Qualified transportation plans cannot reimburse expenses incurred after employment ends. This means terminated employees are ineligible for post-employment transit reimbursements.
  2. No-Refunds Rule
    Unused balances—whether from employer contributions or pre-tax salary reductions—cannot be refunded to the employee. These funds must remain within the plan.

What Can Terminated Employees Do?

Employees who leave the company can still submit reimbursement requests for qualified transportation expenses incurred during employment, as long as they do so within the plan’s run-out period—a grace period for submitting claims after coverage ends.

However, if they:

  • Don’t have enough eligible expenses,
  • Miss the run-out deadline, or
  • Have excess contributions,

…those unused funds are forfeited.

Minimizing Forfeiture Risk Through Plan Design

Employers can reduce forfeiture risk by designing the plan thoughtfully. For example:

  • Limit monthly contributions to the cost of a transit pass.
  • Send regular reminders to employees about their balances and deadlines.
  • Allow election changes to avoid over-contributing.

What Happens to Forfeited Funds?

Your plan document should clearly state how forfeited balances are handled. Options include:

  • Retaining funds to cover plan administration costs.
  • Redistributing funds to other participants (within IRS limits).
  • Complying with state escheat laws, especially if the plan is “funded” (i.e., money held in separate accounts).

Qualified transportation plans offer great benefits, but they come with strict IRS rules. By understanding the limitations and designing your plan carefully, you can support your employees while minimizing forfeitures and compliance risks.
