Commuter Benefits in 2026: The IRS Raised Pre-Tax Transit and Parking Limits to $340/Month

Commuter Benefits in 2026: The IRS Raised Pre-Tax Transit and Parking Limits to $340/Month​

Ask a small business owner what they offer employees, and you'll hear health insurance, maybe a 401(k) match, maybe unlimited PTO. Almost nobody mentions commuter benefits — even though they're one of the cheapest, easiest perks to set up, and even though a growing list of cities will fine you for not offering them.

The IRS just made the math better. Starting January 1, 2026, employees can set aside up to $340 per month tax-free for transit and a separate $340 per month for qualified parking — up from $325 in 2025. That's $8,160 a year, combined, that an employee can pull out of their paycheck before income and payroll taxes touch it. And because the money comes off the top of taxable wages, the employer saves money too, not just the employee.

Here's what changed, how the benefit actually works, and why "we're too small to worry about this" is increasingly not true.

What Actually Changed for 2026​

The IRS adjusts the qualified transportation fringe benefit limit annually for inflation under Section 132(f) of the tax code. For 2026, that adjustment (via Revenue Procedure 2025-32) pushed both caps up by $15 a month:

• Transit passes, vanpools, and commuter highway vehicles: $340/month (up from $325 in 2025)
• Qualified parking: $340/month (up from $325 in 2025)
• Combined annual ceiling: $8,160 if an employee maxes out both categories

These are separate buckets. An employee who takes the train to a park-and-ride lot can use up to $340 pre-tax for the train pass and up to $340 pre-tax for the parking spot — $680 a month, tax-free, if both legs of the commute qualify.

One easy-to-miss detail: the IRS doesn't require employers to adopt the new limit automatically. If your plan document or payroll provider still has $325 hardcoded, you need to update it. Left alone, some plans quietly cap employees below the legal maximum, which just means employees pay more tax than they have to for no reason.

Anything above the monthly cap is taxable. If you give someone a $400/month parking stipend, $340 comes out pre-tax and the remaining $60 gets added back to taxable wages for both income and payroll tax purposes — same as any other fringe benefit that exceeds its statutory limit.

How the Benefit Actually Works​

A commuter benefit is a pre-tax payroll deduction, similar in mechanics to a health FSA, but for getting to work instead of getting healthy.

1. The employee elects a monthly amount (up to the IRS cap) to set aside from their paycheck.
2. That amount is deducted before federal income tax, Social Security, and Medicare tax are calculated.
3. The employee uses a debit card, voucher, or reimbursement process (usually through a third-party administrator) to pay for transit passes, vanpool fares, or parking.

Employers can also contribute to the benefit on top of what employees defer, as long as the combined total stays under the monthly cap — some businesses use this as a low-cost perk instead of a straight raise, since a dollar of commuter benefit costs the employer less than a dollar of taxable salary once payroll tax savings are netted out.

What qualifies:

• Transit passes for buses, subways, trains, and ferries
• Vanpool fares (commuter highway vehicles)
• Parking at or near the workplace, or at a location employees use to commute onward via transit

What doesn't qualify: the bicycle commuting benefit that used to be part of this program is still suspended under the 2017 tax law through 2025, and nothing in the 2026 update revives it — so mileage or gear for cycling to work isn't part of this pre-tax bucket.

The Payroll Tax Savings Employers Are Leaving on the Table​

Because commuter benefit deductions lower taxable wages, employers avoid the 7.65% employer-side FICA match (Social Security plus Medicare) on every dollar an employee defers.

Run the numbers on a modest program:

• One employee deferring $300/month = $3,600/year in reduced taxable wages = roughly $275/year in employer FICA savings on that person alone.
• A 30-person company where everyone maxes out the benefit can see employer payroll tax savings well into five figures a year, purely from the payroll math — before counting any productivity or retention upside from a perk employees actually use.

That's real money that shows up as a reduction in payroll tax expense, not a marketing claim. If you're already running payroll, the incremental cost of adding a commuter benefit administrator is often smaller than what you save in the first year, especially once more than a handful of employees participate.

When You're Legally Required to Offer This​

This is the part most small business owners don't know until they get a compliance letter: several cities and one state now require employers above a certain headcount to offer pre-tax commuter benefits, regardless of whether the employer wants to.

• New York City: Employers with 20 or more full-time employees anywhere in the five boroughs must offer a pre-tax transit benefit (parking is not required).
• San Francisco: Employers with 20 or more employees working an average of 10+ hours a week must offer commuter benefits — and because the ordinance is based on where employees work rather than where the company is headquartered, it can reach employers based outside the city.
• Seattle: Employers with 20 or more employees must offer pre-tax commuter benefits to anyone working an average of 10+ hours a week within city limits, regardless of residency.
• New Jersey: The only statewide mandate. Employers with 20 or more employees working in New Jersey — full-time, part-time, or remote workers physically located in the state — must offer a pre-tax transit and vanpool benefit. Employers must keep records for six years showing every eligible employee was offered the benefit, and non-compliance carries fines starting at $100–$250 for a first violation and $250 for every additional month after a 90-day cure period.
• Washington, D.C. and a handful of other jurisdictions have similar 20-employee-threshold ordinances.

The pattern across nearly every mandate is the same 20-employee trigger. If you're a growing business crossing that headcount — especially one with remote employees scattered across NJ, NYC, or the Bay Area — it's worth checking whether you've quietly crossed into mandatory territory. The determining factor is usually where the employee works, not where the company is legally domiciled, which catches a lot of remote-friendly small businesses off guard.

Even where it isn't required, adoption is still low: only about 12% of employers nationally offer a transit subsidy and 10% offer a parking subsidy, according to recent benefits data. That means offering one — even a modest, employee-funded, no-employer-match version — is a genuine differentiator in a tight hiring market, not just a compliance checkbox.

Setting It Up Without Overcomplicating Your Books​

If you decide to add (or update) a commuter benefit program, keep the bookkeeping side simple:

• Treat elections as a payroll deduction, not a reimbursement, if you're using a debit-card model — it flows through payroll like an FSA or HSA contribution and reduces taxable wages automatically.
• Track the employer-paid portion separately from the employee-deferred portion if you contribute anything on top, so you can see the actual cost to the business versus what's simply redirected employee salary.
• Reconcile the third-party administrator's monthly invoice against payroll deductions the same way you'd reconcile a benefits carrier bill — mismatches here are usually a stale plan-year cap or a terminated employee whose deduction wasn't turned off.
• If your business crosses a city or state mandate threshold, document that the benefit was offered to every eligible employee, even those who decline it — several ordinances require proof of the offer, not just proof of participation.

Payroll and benefits deductions are exactly the kind of line item that's easy to get wrong in a spreadsheet and easy to audit in a system built for it. Keeping commuter benefit deductions, employer contributions, and the administrator's fees in clearly separate accounts — rather than lumped into a generic "payroll expense" category — makes it far easier to answer basic questions later: how much did this program actually cost us, and is participation worth the administrative overhead?

Keep Your Books as Clear as Your Commute​
