Commuter Benefits Overview: Part I

By Brian Gilmore | Published April 23, 2025

Question: What are the tax-advantaged commuter benefits that employers can offer to employees?

Short Answer: Employers can provide tax-advantaged mass transit, vanpool, and qualified parking benefits to employees. The monthly limit for mass transit and vanpooling is aggregated, but the monthly limit for qualified parking is separate. Employees can therefore take advantage of the full limit for both transit pass/vanpooling and qualified parking.

Starting Point: Three Forms of Qualified Transportation Fringe Commuter Benefits Employers can provide three types of tax-advantaged commuter benefits to employees under Internal Revenue Code §132(f):

1. Transit Passes (Mass Transit)
2. Commuter Highway Vehicles (Vanpooling)
3. Qualified Parking

Commuter Benefit #1: Transit Passes (Mass Transit) 2025 Limit: $325/month (combined with vanpooling) “Transit passes” are defined as any pass, token, farecard, voucher, or similar item that entitles a person to transportation on mass transit facilities. Common examples include bus, train, subway, ferry, and light rail.

Commuter Benefit #2: Commuter Highway Vehicles (Vanpooling) 2025 Limit: $325/month (combined with transit passes) Vanpooling is transportation in a “commuter highway vehicle” in connection with travel between the employee’s residence and place of employment.

A “commuter highway vehicle” generally must meet two requirements:

1. Capacity: The vehicle must have a seating capacity of at least six adults (excluding the driver); and
2. The 80/50 Rule: At least 80% of the vehicle’s mileage is reasonably expected to be for commuting employees on trips during which at least 50% of the adult seating capacity (excluding the driver) is filled with such commuting employees.

Note: The 80/50 rule does not apply to private or public transit-operated vanpools. Therefore, where available, ride-sharing services can qualify for vanpooling based only on the vehicle meeting the capacity requirement of having seating for at least six adults, not including the driver.

Commuter Benefit #3: Qualified Parking 2025 Limit: $325/month “Qualified parking” is defined as parking in either of two locations:

1. Business Location: Parking on or near the employer’s business premises; or
2. Transit Location: Parking at a location from which the employee commutes to work.

The business location option does not include expenses for parking at home. The transit location option includes parking at a place from which to commute by mass transit, carpool, commuter highway vehicle, or any other form of paid transportation services.

• Note: Qualified parking does not include parking at a temporary work location, which is defined as a location that is realistically expected to last (and does in fact last) for one year or less.

Mass Transit/Vanpool Limit Not Combined with Qualified Parking Limit The mass transit/vanpool monthly tax-advantaged limit is not combined with the qualified parking monthly tax-advantaged limit. Accordingly, employees can take advantage of up to the maximum of both the mass transit/vanpool benefit and the qualified parking benefit each month.

Example 1:

• Robert Paulson is an automobile recall specialist working in downtown Los Angeles.
• He drives to the local metro rail station and rides the light rail to the office daily.

Result 1:

• Robert can contribute up to $325/month (2025) pre-tax to his qualified parking benefit.
• He can also contribute up to $325/month (2025) pre-tax to his mass transit benefit.
• Robert’s combined pre-tax commuter benefit of $650/month does not exceed any applicable limit.

Combined Employer/Employee Monthly Contribution Limit Section 132(f) provides a tax-advantaged limit of $325 per month (2025) that may be contributed to a transit pass/vanpooling and/or qualified parking commuter benefit program. These limits are adjusted annually for inflation.

Both employer and employee contributions count toward the $325 monthly limit.

Example 2:

• Judy Bernly works at Consolidated Companies in downtown San Francisco.
• She drives to the local BART station and takes BART to work.
• Consolidated Companies provides a mass transit/vanpooling and qualified parking subsidy of $100/month.

Result 2:

• Judy can contribute up to $225/month (2025) pre-tax to her qualified parking benefit.
• She can also contribute up to $225/month (2025) pre-tax to her mass transit benefit.

Taxable Commuter Benefits Permitted for Amounts in Excess of Monthly Limit Where employee pre-tax contributions and/or employer tax-free commuter contributions reach the $325/month limit, amounts in excess of the limit are permitted if included in the employee’s taxable income. Many commuter benefit TPAs offer employee after-tax contributions for excess amounts.

Example 3:

• Peter Gibbons spends $400/month taking the bus to his job as a computer programmer.
• Initech Corporation offers a mass transit commuter benefit program that allows employees to contribute up to the $325/month limit on a pre-tax basis.

Result 3:

• Peter can contribute $325/month on a pre-tax basis and $75/month on an after-tax basis.

Substantiation of Use of Commuter Benefits for Employee’s Commute to Work Mass Transit: No Substantiation Required There are no §132(f) substantiation requirements to confirm that employees are using the mass transit benefit exclusively to commute to work.

Qualified Parking: Substantiation Required Unlike transit passes, qualified parking benefits may be used only by employees in connection with their commute to their places of employment. Employees must substantiate any parking expenses reimbursement request “within a reasonable period of time.” The regulations establish an outer limit of 180 days from the date the parking expense was paid.

State and Local Employer Commuter Benefit Requirements A number of state and local governments have imposed requirements that employers offer commuter benefit programs to employees. Employers can typically satisfy these requirements by offering employees the ability to contribute pre-tax up to the monthly maximum ($325 in 2025) to a mass transit/vanpool and qualified parking arrangement.
