Taxes
Because all or a portion of your transportation costs are deducted from your pay on a before-tax basis (up to IRS-imposed limits), you have the potential to save on your transit and parking expenses.
For example, assume that…
Your transit pass costs:
$100 per month
Your tax rates are:
28% federal income tax
8% FICA (rounded)
4% state income tax
Total taxes = 40%
You would save in taxes:
$40 per month ($100 x 40%)
$480 per year ($40 x 12)
This example is for illustrative purposes and does not reflect an individual's financial situation. Your tax savings, which could be more or less, will depend on your residence state and applicable taxes. Please consult with a personal tax adviser for specific tax questions and advice.
Limits and Exceptions
Note that currently…
  • federal tax law limits the amount of gross wages that you may spend each month on tax-free transit or parking. Currently, the limits are:
    • For transit or vanpool: $265 per month.
    • For parking: $265 per month.
If your transit or parking expense is more than the federal before-tax limit, the excess will be deducted on an after-tax basis. For example, if you elect to purchase your $300 monthly transit pass through TRIP, $265 will be deducted from your pay, but only $265 of the $300 will be deducted on a before-tax basis. The remaining $35 will be deducted on an after-tax basis.
Note: In New Jersey, Pennsylvania and Mississippi, TRIP contributions are subject to state taxes.
What are the limits for before-tax spending if I incur mass transit and parking expenses as part of my daily commute?
Currently, the IRS federal limit for before-tax transit expenses is $265 per month for transportation in a qualified commuter highway vehicle and transit passes. The federal limit for before-tax parking expenses is $265 per month. If you incur transit and parking expenses, the limits remain separate and independent. For example, let's say you pay $300 per month for transit and $245 per month for parking. Since the before-tax limit for transit spending is $265 per month, $265 of your transit expenses will be deducted from your paycheck on a before-tax basis, while the remaining $35 will be deducted on an after-tax basis. For parking, your $245 monthly expense will be deducted in full on a before-tax basis.
My monthly transit pass costs $300. How do I pay for the $35 that cannot be deducted on a before-tax basis? Do I have to write a check for the balance?
No. If your transit or parking expenses exceed the before-tax limits set by the IRS, your remaining expenses are deducted from your paycheck on an after-tax basis. In this case, $265 in transit expenses will be deducted from your paycheck on a before-tax basis, while the remaining $35 will be deducted on an after-tax basis.
If the IRS audits my personal tax records, how can I access my WageWorks' records to document my use of the before-tax commuter benefit?
A record of all of your WageWorks transactions for the current calendar year and a limited number of prior years is available through the "Commuter" page on the WageWorks website under "View Order History". For records no longer available online, you can contact WageWorks directly for your account information.
