Commuter Benefits

Commuter benefits are employer-provided transit, vanpool and parking benefits that Internal Revenue Code section 132(f) excludes from an employee's gross income up to a monthly limit. The Code's own name for them is a qualified transportation fringe; the Internal Revenue Service heads the relevant section of Publication 15-B "Transportation (Commuting) Benefits" and its annual inflation notice "Qualified Transportation Fringe Benefit". None of those three names is "commuter benefits", which is the name the market settled on and the one most employees will see on a benefits portal.

Section 132(f)(1) lists exactly three things: transportation in a commuter highway vehicle between home and work, any transit pass, and qualified parking. A benefit that is not one of those three is not a qualified transportation fringe, whatever an employer calls it. The benefit may be provided directly, through a voucher, or as a cash reimbursement, though section 132(f)(3) allows cash reimbursement for a transit pass only where a voucher exchangeable solely for a transit pass is not readily available to the employer.

The two limits are two limits, and this is the single most misstated fact about the benefit. Section 132(f)(2)(A) caps the aggregate of vanpool transportation and transit passes at $340 a month. Section 132(f)(2)(B) separately caps qualified parking at $340 a month. The two figures are equal in the current year, they have not always been, and section 132(f)(6) indexes each of them on its own from a 1997 base. Publication 15-B states the point plainly: "You may provide an employee with any one or more of these benefits at the same time." The regulation is more explicit still — 26 CFR 1.132-9 Q/A-14, Example 1, approves an arrangement letting employees reduce compensation by the sum of the transit and parking limits in a single month. Anyone who reads the two amounts as one combined ceiling has halved the benefit for a reader who drives to a station and takes a train from it.

Why it works without a cafeteria plan. Section 125(f)(1) defines a cafeteria plan's qualified benefits by excluding, among others, anything excludable under section 132 — so a transportation fringe cannot be offered through a cafeteria plan at all. Section 132(f)(4) fills the gap with its own constructive-receipt rule: "No amount shall be included in the gross income of an employee solely because the employee may choose between any qualified transportation fringe and compensation which would otherwise be includible in gross income of such employee." That one sentence is the entire legal basis for the pre-tax payroll deduction, and it is why commuter benefits sit in a different administrative box from health premiums even though they look identical on a pay stub.

There is no annual deadline, and that surprises people who know FSAs. 26 CFR 1.132-9 Q/A-15 answers the carryover question with a flat "Yes. An employee may carry over unused compensation reduction amounts to subsequent periods under the plan of the employee's employer." The regulation's own example turns on the employer permitting it, so carryover is allowed rather than required, but nothing forces a forfeiture at year end.

Leaving is where the money is lost, and the rule is a regulation rather than an employer policy. Q/A-14(d) provides that a plan "may not provide that an employee who ceases to participate in the employer's qualified transportation fringe benefit plan (such as in the case of termination of employment) is entitled to receive a refund of the amount by which the employee's compensation reductions exceed the actual qualified transportation fringes provided to the employee by the employer." The bar sits in the regulation rather than in the plan's design, so a departing employee with a built-up transit balance cannot be paid it out even by an employer that would like to. Spending the balance down before a planned departure is the only remedy.

The election must be prospective. Q/A-14(b) requires the election to be made before the employee could currently receive the cash, and the period the benefit covers must not begin before the election is made. Q/A-14(c) then bars revocation once the period has begun. A reimbursement claimed for a month that preceded the election is taxable wages, which is the trap in the regulation's own second example.

Not everyone is an employee for this purpose. Section 132(f)(5)(E) provides that "employee" here does not include an individual who is an employee within the meaning of section 401(c)(1), which removes the self-employed, partners and sole proprietors. Publication 15-B adds that a more-than-2-percent shareholder of an S corporation is treated like a partner and cannot take the exclusion either.

The employer gets nothing back, and that is why some employers dropped the benefit. Publication 15-B notes that sections 274(a)(4) and 274(l) of the Code allow no deduction for qualified transportation benefits incurred or paid after 2017, whether provided directly, through a reimbursement arrangement or through a compensation reduction. The exclusion for the employee survived that change; the employer's deduction did not.

One historical point, stated once. The qualified bicycle commuting reimbursement was suspended in 2017 and has now been permanently eliminated rather than restored. The fringe benefits entry covers that change and the indexing base-year shift that came with it.

Two definitional details worth knowing before you rely on the benefit. A "commuter highway vehicle" under section 132(f)(5)(B) must seat at least six adults excluding the driver, with at least 80 percent of its mileage reasonably expected to be commuting trips on which at least half the adult seating capacity is occupied — a real vanpool, not a carpool. And "qualified parking" under section 132(f)(5)(C) is parking at or near the employer's premises, or at or near a place you commute from by transit, vanpool or carpool; it expressly excludes "any parking on or near property used by the employee for residential purposes."

1. The employer sets up a plan offering one or more of the three categories, either paying for them directly or letting employees redirect salary.

2. The employee elects an amount before the period begins. The regulation measures the election against the period the benefit covers, so a plan administered month by month has to take the election before that month starts, and no election can be applied retroactively.

3. Payroll withholds the elected amount before tax, so it is excluded from income tax withholding and from Social Security and Medicare wages.

4. The benefit is delivered as a pass, a transit card load, a parking arrangement, or a reimbursement of substantiated expenses.

5. Anything above the monthly limit is wages. Publication 15-B: if the value of a benefit for any month exceeds its limit, the excess minus any amount the employee paid is included in the employee's wages, and it cannot be rescued as a de minimis transportation benefit.

A hypothetical illustration of the saving. Priya parks at a commuter rail station for $150 a month and buys a $200 monthly rail pass. Both amounts sit under their respective statutory limits, and they are not added together for that test, so both are fully excludable.

Her total pre-tax election is $150 + $200 = $350 a month, or 350 × 12 = $4,200 a year. Suppose her combined marginal rate is 22 percent federal income tax, 7.65 percent Social Security and Medicare tax, and 5 percent state income tax, a combined 34.65 percent. The tax she does not pay is 4,200 × 0.3465 = $1,455.30 for the year.

Now change one fact. If the two limits were a single combined ceiling — the way they are commonly described — Priya would be over it and part of her $350 would be taxable wages. They are not, and she is not. All figures are illustrative; the statutory limits are the ones published each year by the Internal Revenue Service.

Pros

• The exclusion reaches Social Security and Medicare tax as well as income tax, so the saving is larger than the marginal income-tax rate alone.
• Transit and parking are separately capped, so a reader who drives to a station and takes a train can use both in full in the same month.
• There is no annual forfeiture deadline: unused compensation reductions carry forward with the same employer.
• It requires no cafeteria plan, so a small employer can offer it without adopting one.
• The benefit is real money for a fixed, predictable expense most commuters are paying anyway.

Cons

• Whatever is left in the account is forfeited when you leave, by regulation, with no employer discretion to refund it.
• The election is prospective only and cannot be revoked once the period has begun, so a month of remote work or a changed commute is a month of wasted election.
• The self-employed, partners, and more-than-2-percent S corporation shareholders cannot use it at all.
• The employer receives no deduction for the cost, which removes the incentive to offer it and is one reason some employers have not.
• Nothing outside the three statutory categories qualifies, so rideshare to the office, tolls, mileage and bicycle costs are ordinary taxable spending.
