Body

No. Unspent §132(f) commuter benefits are not taxed as income at year-end. They also can't be refunded to you in cash. The IRS does not allow a cash-out of unused commuter dollars, which is the trade-off for the pretax treatment.

How "use it or leave it" works

Commuter benefits don't expire like FSA dollars at year-end. Unspent balances generally carry forward month to month as long as you remain employed at the same employer and the plan permits it. Specific carryover rules depend on your employer's plan design.

What happens at year-end

If you have a balance on December 31 and you're still employed, it generally rolls into January. It does not become taxable income. You don't claim it as anything on your tax return.

What happens if you leave the plan

If you change jobs or your employer ends the plan, you typically have a short run-out window to use the funds for qualifying commute expenses already incurred. Any balance after that window is forfeited. It is not paid out to you. It is not added back to your taxable wages.

Why this matters for planning

Estimate conservatively. Don't elect $340/month if your actual commute costs $150/month. Election flexibility varies by administrator. Alice supports pay-period flexibility, which means employees can change elections more often than traditional annual-only plans.

The good news

Even if you leave a small balance behind, you've already captured the tax savings on every dollar you spent. The forfeit only applies to the unused portion. Keep more of what you make on what you actually use.
