The $4,080 Unclaimed Raise: Federal Transit Benefit Explained
With five-day return-to-office mandates now in effect for most of the federal workforce, commuting costs that were near-zero during telework years are now a real monthly expense. The federal transit subsidy — authorized by Executive Order 13150 (April 21, 2000) and 5 U.S.C. § 7905, with tax authority under IRC § 132(f) — turns that recurring commuting cost into a fully tax-free benefit.
The 2026 limit is $340/month for transit or vanpool plus a separate $340/month for qualified parking — confirmed in IRS Revenue Procedure 2025-32 and IRS Publication 15-B 2026. The combined maximum is $8,160/year. Up from $325 in 2025 and $315 in 2024.
The Gross Salary Equivalent Formula
Gross Equivalent = Annual Benefit ÷ (1 − Combined Tax Rate)
A GS-11 in Virginia or Maryland at the 22% federal bracket with 5% state income tax has a combined rate of ~34.65%. The $4,080 annual transit benefit divided by (1 − 0.3465) = $6,240 gross raise equivalent (FedTools 2026 analysis).
