Connect transportation benefits to payroll and employee elections

Create separate records for transit passes, qualifying commuter transportation and qualified parking. IRS Publication 15-B describes the categories and their conditions. A payroll code called commuter benefit does not establish that every taxi receipt, parking payment or travel allowance qualifies for the same exclusion.

Give payroll the employer's program terms and the actual benefit provided. Distinguish commuting benefits from business-travel reimbursements and personal vehicle use. Ask the benefits or tax adviser to review unusual arrangements and owner-employees before extending an employee exclusion to everyone receiving a payment.

Retain the employee's authorized salary-reduction election, effective month and later changes. Record employer-funded amounts separately from employee salary reductions and after-tax payments. When a benefit provider bills the employer one combined amount, preserve the employee-level funding detail behind that invoice.

Match the payroll deduction file to the provider's accepted orders or benefit loads. Investigate rejected enrollments, canceled passes and employees omitted during a payroll migration. An amount withheld from pay does not prove that the transit or parking benefit was made available to the intended employee.

For an illustrative monthly benefit funded by $100 from the employer and $200 of employee salary reduction, the combined funding is $300. Keep both components in the review. Looking only at the employer's cost would omit most of the benefit being assessed against the applicable exclusion rules.

For 2026, Publication 15-B states a $340 monthly exclusion for qualified parking and a separate $340 monthly exclusion for commuter highway transportation and transit passes combined. Confirm the benefit's eligibility as well as its value. Being below a limit does not make a nonqualifying arrangement tax-free.

Prepare a month-by-month schedule, retaining any after-tax employee contribution and the adviser's treatment of excess amounts. Do not compare only an annual total with twelve times a monthly limit. A high benefit in one month and a low benefit in another require the monthly rules to be applied correctly.

If benefits change during the year, preserve the effective dates and source records. Ask payroll to review the taxable portion and reporting period before releasing a catch-up adjustment. Reconcile any change with the provider's records so a corrected wage amount is supported by the benefit actually supplied.

Publication 15-B contains specific conditions for cash reimbursement arrangements, including transit-pass restrictions. Have the adviser approve the process before treating a cash allowance as an excluded benefit. Keep the evidence required by that process with the employee's request and the resulting payment.

At close, reconcile payroll deductions, employer expense, provider invoices and unpaid funding. Give the tax preparer the benefit categories and employer-paid amounts for the employer's deduction review; employee wage exclusion and employer deductibility are separate questions.

Retain outstanding provider credits or unused balances with the program's approved treatment. When an employee leaves, use the documented process for remaining amounts and stop future deductions on the correct date. Confirm the final payroll and provider status rather than assuming one system automatically updates the other.
