Commuter Benefits: An Employer Guide to Section 132(f)
Commuter benefits let employees pay transit and parking with pre-tax dollars under IRC 132(f). The monthly limits, payroll mechanics, and city mandates.
Commuter Benefits
Qualified transportation fringe benefits under section 132(f) of the tax code: what an employer can offer before tax, the separate monthly caps for transit and parking, how the deduction moves through payroll, what the employer does and does not get to deduct, and the cities and states where offering the benefit is a legal requirement rather than a perk
A new hire asked me at the end of her first week whether she could put her monthly transit pass through payroll before tax. I said I would find out. What I found was not a nice extra sitting unused in a drawer. It was a city law we were already supposed to be following.
Commuter benefits are one of the few places where the tax code, the payroll system and a local ordinance all point at the same small administrative task. Set it up once and it costs almost nothing to run. Skip it in the wrong city and it stops being a benefit question and becomes a compliance finding with a penalty schedule attached.
This is the employer view. What section 132(f) lets you offer before tax, the current monthly caps, how the deduction moves through payroll, what you do and do not get to deduct, and the jurisdictions where offering it is mandatory. I build the people and records tooling for small businesses without a dedicated HR person at FirstHR, and FirstHR is an onboarding and HR platform, not a payroll provider. This is general information rather than tax advice.
What Commuter Benefits Are
Commuter benefits are employer-provided transportation benefits that are excluded from an employee taxable wages under section 132(f) of the Internal Revenue Code. The employee pays for the commute with money that never gets taxed, and both sides skip payroll tax on the same amount.
The statutory framework sits in the fringe benefit rules (26 U.S.C. 132), which is the same section that governs the wider family of fringe benefits an employer can provide tax free.
One structural point causes more confusion than anything else on this topic. A qualified transportation fringe is not a cafeteria plan benefit. It does not live inside a section 125 arrangement and it does not behave like a health flexible spending account, even though the two get bundled together by administrators and described with the same vocabulary.
The Three Ways to Offer It
There are three delivery models, and they differ enormously in what they cost you. The tax treatment for the employee is identical across all three.
For a small business the honest starting point is the pre-tax election. It satisfies most of the legal mandates, it costs nothing in cash, and it is the version employees ask for by name.
The Monthly Limits
For 2026 the monthly exclusion is $340 for transit passes and commuter highway vehicle transportation combined, and a separate $340 for qualified parking. The caps do not share a pool, so an employee with both expenses can exclude up to $680 a month.
The figures are indexed for inflation and move most years, which the IRS publishes each autumn and restates in the employer guide to fringe benefits (IRS Publication 15-B). A payroll configuration set once and never revisited will quietly cap people below the current ceiling.
| Expense | Qualifies | Monthly cap |
|---|---|---|
| Transit passes, fare cards, and vouchers | Yes | $340, shared with vanpool |
| Vanpool in a commuter highway vehicle | Yes, where the vehicle seats at least six adults besides the driver and is used mainly for commuting | $340, shared with transit |
| Parking at or near the workplace | Yes | $340, separate |
| Parking at a transit stop or park and ride | Yes | $340, separate |
| Bicycle commuting reimbursement | No, the exclusion is eliminated for tax years beginning after 2025 | None |
| Fuel, tolls, mileage, and personal car costs | No | None |
| Residential parking at the employee home | No | None |
Anything provided above a monthly cap is ordinary taxable wages. It gets withheld on and reported like any other imputed income, which is a small mechanical problem rather than a disaster, but it does need to be caught in the pay run rather than at year end.
How It Runs Through Payroll
Mechanically this is a pre-tax deduction code with a hard monthly ceiling and a specific delivery step at the end. The sequence matters more than the paperwork.
None of this needs a dedicated benefits system, but it does need a deduction setup somebody owns. The failure mode I see most often is a correct configuration in month one that nobody updates when the statutory limit changes.
What It Costs the Employer
The employer keeps the payroll tax saving and loses the income tax deduction. Both halves of that sentence surprise people, and the second half changed under the 2017 tax law.
| Item | Employee-funded election | Employer-paid subsidy |
|---|---|---|
| Who funds it | The employee, from gross pay | The employer, on top of pay |
| Employee income tax | Not owed on the excluded amount | Not owed on the excluded amount |
| Social Security and Medicare tax | Not owed by either side on the excluded amount | Not owed by either side on the excluded amount |
| Employer income tax deduction | Disallowed under section 274(a)(4) | Disallowed under section 274(a)(4) |
| Cash cost to the employer | Administration fees only | The subsidy plus administration fees |
| Amount above the monthly cap | Taxable wages, withheld as normal | Taxable wages, withheld as normal |
The deduction disallowance is the piece employers miss. Section 274(a)(4) removes the employer deduction for the cost of providing qualified transportation fringes, and the position extends to amounts funded through a compensation reduction agreement rather than only to employer-paid subsidies.
What survives is the payroll tax arithmetic. Excluded amounts are not wages, so the employer share of Social Security and Medicare tax does not apply to them, and neither does federal unemployment tax. On a team where several people run a full transit election, that saving is a genuine line item rather than a rounding error in the cost of benefits per employee.
Set against the rest of a benefits package, an employee-funded commuter arrangement is close to unique: it improves take-home pay for the people who use it, costs the employer almost nothing, and needs no insurance carrier, no renewal, and no annual negotiation.
Where It Is Required
Several jurisdictions require covered employers to make a commuter benefit available. The obligation is almost always to offer the pre-tax election, not to pay for anything.
| Jurisdiction | Who is covered | What must be offered |
|---|---|---|
| New York City | Employers with 20 or more full-time non-union employees in the city, full-time meaning an average of 30 or more hours a week in the most recent four weeks | A pre-tax election for transit and commuter highway vehicle expenses. Parking is not covered |
| San Francisco | Businesses with a San Francisco location, once total headcount passes the threshold in the city ordinance | A pre-tax election, an employer-paid transit subsidy, or employer-provided transportation |
| Bay Area, nine counties | Employers with 50 or more full-time employees in the Air District nine-county jurisdiction, under Regulation 14, Rule 1 | One of several options including a pre-tax election, an employer subsidy, or employer-provided transportation |
| Washington DC | Employers with 20 or more employees in the District, counting full-time and part-time alike | A pre-tax election, an employer-paid transit benefit, or employer-provided transportation |
| New Jersey, statewide | Employers above the headcount threshold in the state law, with workers covered by a collective bargaining agreement treated separately | A pre-tax election for transit passes and commuter highway vehicle travel. Parking is optional |
| Philadelphia | Employers above the headcount threshold in the city ordinance, counting employees who work a regular weekly schedule inside city limits | A pre-tax election for mass transit fares, an employer-paid fare benefit, or a combination |
| Seattle | Employers with 20 or more employees, covering employees who average 10 or more hours a week in Seattle | A pre-tax election for transit or vanpool, or a fully or partly subsidized transit pass |
| Chicago region, Illinois | Employers above the headcount threshold in the Transportation Benefits Program Act, at a covered location near fixed-route transit | A pre-tax election for a transit pass, available once an initial period of employment is complete |
New York City is the one small employers trip over most often, and the reason is the carve-outs rather than the headline number. The law reaches full-time non-union employees who average 30 or more hours a week, any part of it worked in the city, and it covers transit and vanpool only. Parking sits outside it entirely. The city publishes the employer requirements and the enforcement approach directly (NYC Department of Consumer and Worker Protection).
Thresholds and covered-employee definitions differ from one program to the next, and they get amended. Confirm the current figure with the agency that administers each program before you decide you are exempt, because the count that matters is rarely the one on your org chart.
Penalties are modest by design and escalate with stubbornness. In New York City an employer gets 90 days to cure before any penalty can be imposed, then $100 to $250 for a first violation, and a further $250 for every additional 30-day period of non-compliance after that. Nobody is going out of business over this. Nobody enjoys the letter either.
What Does Not Qualify
The exclusion is narrower than the phrase commuter benefits suggests. Three categories qualify, and everything outside them is ordinary taxable pay however commute-related it feels.
Fuel, tolls, mileage and wear on a personal car are outside section 132(f) entirely. An employer who wants to help with driving costs is looking at a vehicle stipend or a mileage reimbursement, which follow completely different rules and produce completely different tax outcomes.
Ride hailing and taxi fares generally do not qualify unless the vehicle meets the commuter highway vehicle test, which requires seating for at least six adults besides the driver and use principally for commuting. A shared ride in an ordinary car does not clear that bar.
Owners are the other gap. The exclusion applies to employees, so sole proprietors, partners, independent contractors and more-than-2-percent S corporation shareholders sit outside it. Employees of the business are covered normally, which means the arrangement still works for the team even where the founder cannot personally use it.
Setting One Up
Most of the work is decisions and configuration. The administration itself is light once the deduction codes exist.
Where Small Employers Get This Wrong
Five patterns, and the first two are the ones that cost real money.
Not checking the local mandate is first. Employers assume a commuter benefit is optional everywhere, which is true in most of the country and false in exactly the metro areas where hiring is hardest.
Combining the transit and parking caps is second. They are separate ceilings, and merging them either caps people early or creates a taxable overage that surfaces during year-end reconciliation.
Treating it as a cafeteria plan benefit is third. It is not one, and the plan documents, election rules and forfeiture behavior are all different from a health account.
Refunding an unused balance in cash is fourth. It feels like the fair thing to do for a departing employee and it disqualifies the arrangement.
And announcing it once is fifth. Take-up is a communication problem, not a design problem, which is why this belongs in the onboarding checklist rather than in the annual benefits communication cycle.
Frequently Asked Questions
What are commuter benefits?
Commuter benefits are employer-provided transportation benefits that qualify for exclusion from an employee taxable wages under section 132(f) of the Internal Revenue Code. The formal name is a qualified transportation fringe. Three categories qualify: transit passes, transportation in a commuter highway vehicle such as a vanpool, and qualified parking at or near the workplace or a park and ride lot. The benefit can be funded by the employee through a pre-tax salary reduction, paid for by the employer, or split between the two. Because the amounts are excluded from wages, neither side pays payroll tax on them, which is where the savings come from.
What is the monthly limit for commuter benefits?
For 2026 the monthly exclusion is $340 for transit passes and commuter highway vehicle transportation combined, and a separate $340 for qualified parking, according to IRS Publication 15-B. The two caps do not share a pool, so an employee who both rides transit and pays to park can exclude up to $680 a month in total. The figures are indexed for inflation and move most years, which means a payroll configuration set once and forgotten will quietly cap people below the current ceiling. Anything an employer provides above the monthly limit is ordinary taxable wages subject to withholding and reporting in the period it is provided, so the overage needs to be caught in the pay run rather than at year end.
Are commuter benefits pre-tax?
Yes, within the monthly caps. Amounts an employee elects to have withheld for transit, vanpool, or qualified parking come out of gross pay before federal income tax and before Social Security and Medicare tax, and the same amounts are outside federal unemployment tax as well. Employer-paid amounts are excluded from wages in the same way. One important detail catches people out: qualified transportation fringes are not cafeteria plan benefits, so they do not sit inside a section 125 plan and do not follow the health flexible spending account rules. That difference changes how elections work, what happens to unused balances, and which plan documents you actually need.
Do employers save money on commuter benefits?
Employers save the employer share of Social Security and Medicare tax on every dollar excluded from wages, which is 7.65 percent of the amount for most workers up to the wage base. That saving is real and it applies whether the employee funds the benefit or the employer does. What employers no longer get is an income tax deduction: section 274(a)(4) of the tax code disallows the deduction for the cost of providing qualified transportation fringes, including amounts funded through a salary reduction. So the payroll tax saving stays and the deduction goes, which makes an employee-funded election far more attractive than an employer-paid subsidy on pure economics.
Which cities require employers to offer commuter benefits?
Several jurisdictions require covered employers to make a commuter benefit available, and the duty attaches to the location of the worksite rather than to where the company is headquartered. New York City, San Francisco and the wider nine-county Bay Area, Washington DC, New Jersey, Philadelphia, Seattle and the Chicago region all run a program. New York City covers employers with 20 or more full-time non-union employees in the city, Washington DC covers employers with 20 or more employees in the District counting full-time and part-time alike, the Bay Area program covers employers with 50 or more full-time employees in the nine-county Air District, and Seattle covers employers with 20 or more employees. The others set their own thresholds and their own definition of a covered employee, so confirm the current figure with the administering agency before deciding you are exempt.
Can employees get unused commuter benefit money back?
No. Unused amounts in a commuter benefit arrangement cannot be refunded to the employee in cash, and doing so would disqualify the arrangement. What the money can do is carry forward. Unlike a health flexible spending account, a qualified transportation fringe has no use it or lose it deadline at the plan year end, so under IRS rules an employee may carry unused amounts over to later periods under the employer plan and spend them on future qualified expenses. The practical risk is a departing employee. Somebody who leaves with a large balance generally forfeits it, which is a good reason to keep elections close to actual monthly spending rather than banking a cushion.
Are bicycle commuting reimbursements still tax free?
No. The qualified bicycle commuting reimbursement exclusion was suspended by the 2017 tax law for tax years 2018 through 2025 and was scheduled to return, but Public Law 119-21 eliminated it permanently for tax years beginning after 2025. IRS Publication 15-B reflects that change. An employer can still choose to help people who cycle to work, and plenty do, but the payment is ordinary taxable wages to the employee and has to run through payroll with withholding like any other cash compensation. Treating it as a tax-free reimbursement is a reporting error rather than a policy choice, and it is the kind of error that surfaces in a payroll audit long after the money has gone out.
Can owners and contractors use commuter benefits?
Generally no. The section 132(f) exclusion applies to employees, and self-employed individuals are outside it. That covers sole proprietors, partners in a partnership, independent contractors, and more-than-2-percent shareholders in an S corporation, who are treated like partners for fringe benefit purposes. It is a common and expensive surprise for owner-operators who assumed they could route their own parking through the arrangement. Employees of the business are covered normally, so the arrangement still works for the team even where the founder cannot personally participate. Confirm the treatment of any owner with your tax adviser before setting elections up, because the fix after the fact is a corrected return rather than a quiet adjustment in the next pay run.
