If you commute to work by public transit, ferry, vanpool, or paid parking, your employer may offer one of the most underused benefits in the tax code: commuter benefits, also known as transportation fringe benefits or qualified transportation accounts. These let you pay for transit passes and parking with pre-tax dollars — saving the equivalent of 25% to 40% on those expenses depending on your tax bracket.
How Commuter Benefits Work
Section 132 of the IRS code lets employers offer pre-tax transportation accounts. You designate a monthly amount to be withheld from your paycheck before federal income tax, Social Security, and Medicare are calculated. The money loads onto a commuter benefits card or transit account that you use for qualified expenses.
For 2025, the IRS monthly pre-tax limits are:
- Transit and vanpool — $325 per month
- Qualified parking — $325 per month
You can stack both limits ($650/month total) if you, say, drive to a train station and then take the train. The two categories are independent.
The Tax Savings, Concretely
Consider someone in the 22% federal bracket who pays $250/month for a transit pass plus 7.65% FICA. Using commuter benefits:
- Pre-tax setup: $250 comes out before tax. Saves 22% federal + 7.65% FICA = 29.65% → $74 in monthly tax savings ($888/year)
- Post-tax setup: you’d pay $250 from take-home pay. To net $250, you’d actually need to earn about $355 pre-tax
Add state income tax savings in most states (another 4-9 percentage points) and the effective discount tops 35%. Higher earners in the 32% or 35% bracket can save closer to 40%.
What Counts as Qualified
Qualified transit:
- Bus, subway, commuter rail, light rail, ferry, streetcar passes
- Transit fare cards (Clipper, SmartTrip, OMNY, etc.)
- Vanpools meeting IRS specs (commuter highway vehicle with seating for 6+ adults plus driver, used at least 80% for commuting)
Qualified parking:
- Parking at or near your employer’s premises
- Parking at or near a location from which you commute by mass transit, vanpool, or carpool
- Both monthly contracts and daily parking can qualify
What doesn’t qualify:
- Bicycle commuting (a former $20/month benefit was eliminated in 2017)
- Tolls or mileage for solo driving
- Rideshare for personal use (some employers offer separate vanpool/microtransit programs that may qualify; check carefully)
- Parking at your home
Use-It-or-Lose-It (Mostly)
Unlike an FSA, commuter benefits don’t have a use-it-or-lose-it deadline at year-end — but they’re tied to your employment. If you leave the job, any unused balance is generally forfeited (rules vary by plan). For that reason:
- Match your election to your actual commute — if you only spend $180/month on transit, set $180, not $250. The pre-tax money rolls over month-to-month within the same job, but you can’t get it back if you leave
- Reduce contributions during planned travel or remote work — most plans let you adjust monthly. If you’ll be working remotely for two months, lower or pause your election
- Spend down before leaving a job — if you know you’re departing, run down your balance in the weeks before separation
How to Sign Up
- Ask HR or check your benefits portal — commuter benefits are often hidden in the benefits enrollment menu, sometimes labeled “Section 132,” “Transit Benefit,” or “Pre-Tax Transit”
- Common administrators — WageWorks (now HealthEquity), Edenred Commuter Benefits, Optum Financial, Benefits Resource
- Enrollment is usually monthly — you can change your election each pay period. Not limited to open enrollment
- If your employer doesn’t offer it — in some cities (San Francisco, New York, Washington DC, others), employers above a certain size are required to offer pre-tax commuter benefits. Worth asking if you live in a covered area
When Commuter Benefits Don’t Make Sense
- Hybrid or remote workers — if you only commute occasionally, you may overcontribute and find unused balance harder to spend down
- Plans with high administrative fees — some employers pass through fees that reduce your savings
- Bike commuters — the bike commuter benefit was eliminated; no pre-tax mechanism currently exists
- Self-employed workers — commuter benefits are an employer-sponsored benefit; not available for sole proprietors or contractors
