Commuter benefits look simple until a workforce crosses a city line. One employee wants a subway deduction. Another pays to park near a commuter rail station. A third works from home three days each week. Payroll still has to decide what is eligible, how much is pretax, and whether local law requires the employer to offer it.
The federal tax code answers only part of that problem. State and local mandates decide who must offer a program, which workers receive it, and what records the employer keeps. Those tests rarely match.
Pre tax commuter benefits separate who funds the account from who receives the tax break
A commuter benefit does not always mean the employer pays for the commute. The most common design lets an employee elect a pre-tax payroll reduction from the employee's pre tax income and use that money for eligible transit or parking. An employer may instead contribute its own money, or combine an employer subsidy with an employee election that lowers taxable income and helps employees save on taxes.
That distinction matters in employee communication. “Pretax” describes the tax treatment and timing of the deduction, including how pre tax commuter benefits are funded by the employee rather than treated as an employer subsidy. It does not promise an employer contribution. A clear enrollment notice should state who funds the account, which expenses qualify, the monthly election deadline, and what happens to unused balances.
This program is a qualified transportation fringe benefit under Internal Revenue Code section 132(f), not a health plan election. Employers reviewing it alongside other payroll exclusions can use Benefitra's guide to taxable fringe benefits in 2026 to separate the wage treatment from the benefit label.
Federal tax rules set two separate $340 monthly limits for transit expenses in 2026
For 2026, the irs sets the monthly limits, and an employer may exclude up to $340 a month tax free for combined transit passes and commuter highway vehicle transportation. Qualified parking has its own $340 monthly limit. Employees can contribute up to $340 monthly from pre tax income for transit costs using pre tax dollars, which reduces taxable income. An employee could therefore use both limits in the same month when the facts support both expenses.
IRS Publication 15 B explains that a compensation reduction agreement lets an employee choose eligible transportation instead of taxable cash compensation. Transit pass reimbursements need a bona fide reimbursement arrangement, and cash reimbursement is restricted when a voucher or similar fare instrument is readily available. Any monthly value above the applicable limit, after subtracting what the employee paid, becomes taxable income to the employee because the excess remains part of income.
Bicycle commuting is different. Federal legislation permanently removed the exclusion for qualified bicycle commuting reimbursements for tax years beginning after 2025. A local ordinance may still require a bicycle benefit, as Philadelphia does, but federal tax treatment must be checked separately.
Local commuter benefit mandates use different employee counts
The right question is not, “Does the company have 50 employees?” It is, “Which law counts which employees, over what period, and at what location?” Companies may be legally required to offer commuter benefits in certain cities, and certain employers are legally required to provide commuter benefits to their employees based on city, employee count, and work location. The comparison below shows which employers required to comply under each jurisdiction's own definitions.
| Jurisdiction | Employer trigger | Covered worker | Minimum offer |
|---|---|---|---|
| New York City | 20 full time nonunion employees in the city | Average 30 hours per week | Pretax transit election |
| New Jersey | 20 employees | Employees of the covered employer, subject to statutory exclusions | Pretax transportation fringe benefit |
| Washington DC | 20 employees | Employees working in the District | Pretax election, direct transit benefit, or employer transportation |
| Seattle | 20 employees worldwide | Average 10 hours per week in Seattle in the previous month | Pretax transit or vanpool election, or qualifying transit pass subsidy |
| Philadelphia | 50 covered employees | Average 30 hours per week in Philadelphia during the previous 12 months | Pretax mass transit benefit or qualified bicycle benefit |
| Bay Area regional program | 50 full time employees across Bay Area worksites | At least 20 hours per week, with stated exclusions | Must offer one of five approved options |
| Covered northern Illinois area | 50 covered employees within one mile of fixed route transit | Average 35 hours per week as of June 1, 2026 | Pretax transit pass election after 120 days |
New York City and New Jersey start with 20 employees
New York City's law requires private and nonprofit employers with 20 or more full-time nonunion employees in New York City to offer commuter benefits. Full time means an average of at least 30 hours per week in the most recent four weeks. The employer must provide employees a written offer of the maximum pretax transit election allowed by federal law or a qualifying employer paid transit benefit.
The New York City employer guidance excludes qualified parking from the required offer. Its rules also require two years of records. If the workforce later falls below 20, new employees are not the issue here; workers who were already eligible continue receiving the opportunity while they remain employed.
New Jersey uses a statewide 20 employee threshold, so employers should determine coverage before setting up the benefit. The Department of Labor rulemaking for P.L. 2019, c. 38 defines the required election by reference to federal commuter highway vehicle and transit benefits. The New Jersey Division of Taxation lists a $4,080 annual state exclusion for 2026, equal to 12 times the federal monthly amount.
Washington DC adds a separate parking cashout duty
Washington DC employers with at least 20 employees must offer one of three commuter options: an employee paid pretax benefit, an employer paid direct transit benefit that can be provided as a tax-free subsidy or direct non-taxable income under federal rules, or employer provided transportation. Nonprofit employers are included.
Parking creates another layer. The District Department of Transportation guidance says covered employers that offer free or subsidized parking must choose a clean air fringe benefit, use an approved transportation demand plan, pay a monthly compliance fee, or report an exemption. Reports are generally due every two years, while employers using a transportation demand plan submit survey data annually.
A payroll team can satisfy the transit election and still miss the parking report. Treat them as two tasks with separate owners, since they address different transportation costs and can carry different cost implications.
Seattle counts a worldwide workforce but covers local hours
Seattle's employer count is worldwide. A business with 20 employees across all locations can be covered even when fewer than 20 work in Seattle. The employee test then looks locally: at least an average of 10 hours per week in Seattle during the previous month.
The Seattle Office of Labor Standards says government entities and tax exempt organizations are outside the ordinance. A covered employer may offer the full pretax transit or vanpool election, or pay for all or part of a transit pass under the city's subsidy formula. The first offer is due within 60 calendar days after new employees start, and employees must sign or otherwise enroll to participate in the offered benefit. An accepted benefit must follow within 30 days.
Remote and hybrid schedules can move an employee in or out of the local hours test. Benefits administration should receive actual work location data rather than relying only on the home address in payroll, since that data helps determine which participating employees qualify under the local hours test. Benefitra's analysis of benefits administration technology for mid market employers explains why eligibility data must stay aligned across payroll and enrollment systems.
Philadelphia starts at 50 covered employees in the city
Philadelphia uses a local count of 50 covered employees. A covered employee performs an average of at least 30 hours of work per week within Philadelphia for the same employer during the previous 12 months. Government employers are excluded.
Philadelphia Bill 220337 requires the employer to make at least one program available. One route is a pretax payroll election for mass transit expenses. The other is an employer funded qualified bicycle benefit, subject to the terms in the ordinance.
That second route does not restore the federal bicycle exclusion. Philadelphia can require a benefit while federal tax law treats the payment differently. Payroll should never infer federal exclusion from local eligibility.
Bay Area rules can require a benefit without requiring payroll deductions
The regional Bay Area program covers public, private, and nonprofit employers with at least 50 full time employees across all worksites in the nine county area combined. Full time means at least 30 hours per week for the employer count. Once covered, the employer generally provides benefits to employees working at least 20 hours per week under one approved path, subject to field, seasonal, and temporary worker definitions.
The Bay Area Commuter Benefits Program requires registration, an identified commuter benefits coordinator, employee notice, and implementation records, and the organization must encourage employees through clear notice of the available option. Employers can choose among five paths: pretax benefits, an employer subsidy, employer transportation, an approved alternative benefit, or a qualifying telework policy.
Local rules in San Francisco, Berkeley, Richmond, and San Francisco International Airport use lower thresholds. An employer below the regional count may still have a city duty. Multi location employers should aggregate the regional workforce first, which can apply regional compliance to more employees when the workforce is combined across worksites, then test each local worksite.
Illinois changed its covered employee definition during 2026
The Illinois Transportation Benefits Program Act applies in the statutory northern Illinois transit area when an employer has at least 50 covered employees at an address within one mile of fixed route transit. The required benefit is a pretax payroll election for a transit pass up to the federal limit.
As of June 1, 2026, a covered employee averages at least 35 hours of work per week for compensation on a full time basis. The benefit must be offered beginning with the first full pay period after 120 days of employment. A 2025 handbook may still carry the earlier definition, so Illinois eligibility rules deserve a dated configuration note.
The Act also contains collective bargaining provisions and a construction industry exception for specified represented employees. Employers should apply those provisions to the actual agreement, not the industry label alone.
Los Angeles authorized an ordinance but did not enact one
California's AB 2548 is often described as a Los Angeles commuter benefits mandate. That is incorrect. Government Code section 65080.9 says Los Angeles Metro may adopt a commuter benefit ordinance. The statute granted authority; it did not impose the proposed employer requirement by itself.
Metro studied a regional ordinance in matter 2019 0448. Its June 2019 materials described future development and a target implementation schedule. Metro's complete ordinance record through August 2026 contains no adopted regional commuter benefit ordinance, and the state report database has no filed implementation report.
South Coast AQMD Rule 2202 does exist. It is a separate emissions rule for worksites averaging at least 250 full or part time employees over the prior six months. The current AQMD guidance gives a newly covered worksite 30 days to notify the agency and 90 days after notification to implement and register a compliance option. Do not turn that 250 employee worksite rule into a 50 employee Los Angeles commuter benefit mandate.
Payroll setup should follow the employee's work location
Begin with a location census. For every employee, retain the employing entity, regular work address, actual local hours where a rule uses them, union status, start date, and applicable waiting period. Then map each person to the federal expense categories and the local offer rule.
Use separate deduction codes for transit and qualified parking because they have separate federal limits. Document whether the program is employee funded, employer funded, or split. Confirm that the payment method cannot accidentally use transit only funds for qualified parking expenses or another ineligible purchase, and that funds are delivered through specialized debit cards or transit passes where appropriate.
Properly structured pre-tax commuter benefits can help employers save money on payroll taxes, including FICA taxes.
Employers can handle administration in-house or use a third-party provider or third-party benefits provider.
A practical launch sequence is:
- Identify covered entities and worksites under each jurisdiction's counting rule.
- Test every worker against the local hours, tenure, and bargaining definitions.
- Choose the permitted benefit design, document who pays, and estimate potential savings, the difference in commuting costs, and whether the program could reduce parking demand and company parking expenses.
- Configure separate payroll codes, monthly limits, and effective dates.
- Give employees a plain language notice with election and use instructions, including an example of eligible expenses and how to avoid losing unused funds.
- Reconcile payroll deductions to vendor funding and declined transactions each month.
- Calendar registrations, record retention, annual updates, and threshold retesting.
Benefits communication is part of compliance. An employee who hears only “pretax benefit” may reasonably think the company is paying the fare. Benefitra's employee benefits communication strategy can help turn tax language into an enrollment notice workers can actually use, and free assistance can support that rollout.
Frequently asked questions
Are commuter benefits paid by the employer?
Not necessarily. There are clear advantages to employer-funded or mixed designs, including stronger job satisfaction, better retention and recruitment, and a more engaged workforce when companies provide these benefits to their employees beyond bare compliance. An employee paid pretax election is common and satisfies several local mandates. Other laws allow or require an employer subsidy, transportation service, telework option, or another approved design. The enrollment notice should say who funds each part.
What is the commuter benefits limit for 2026?
The federal exclusion is $340 a month for transit passes and commuter highway vehicle transportation; the irs sets a separate $340 monthly limit for qualified parking, and these are tax free limits when the benefit stays within federal rules.
Can an employee use commuter benefits for ordinary gas or mileage?
Ordinary fuel and mileage for driving a personal vehicle to work are not qualified transportation fringe benefits. Eligible transportation costs include mass transit and qualified parking expenses, along with transit passes and qualifying commuter highway vehicle transportation, subject to the federal definitions, and vanpooling can qualify when the vehicle seats at least six adults and otherwise meets the federal definition.
Do commuter benefits cover remote employees?
Remote status alone does not answer the question. Local mandates use actual work location and, in some cities, a minimum number of hours worked there, so a tax advisor may also be helpful in edge cases. An occasional commute can still create eligible transit or parking expenses, but the election should match expected use to avoid unnecessary balances, help employees save on transit expenses, and avoid overfunding; pre-tax elections can also produce nearly 30% tax savings for some employees, depending on their income and taxes.
Does Los Angeles require employers with 50 employees to offer commuter benefits?
No regional Metro ordinance was enacted through August 2026. AB 2548 authorized Metro to adopt one but did not create the employer duty itself. South Coast Rule 2202 is separate and generally starts at 250 employees at a worksite.
