The $4,080 unclaimed raise, explained
With five-day return-to-office mandates now in effect for most of the federal workforce, commuting costs that were near-zero during the telework years are again a real monthly expense. The federal transit subsidy — authorized by Executive Order 13150 and 5 U.S.C. § 7905, with tax authority under IRC § 132(f) — turns that recurring 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/mo in 2025 and $315/mo in 2024.
A GS-12 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 ÷ (1 − 0.3465) ≈ $6,240 gross raise equivalent (FedTools 2026 analysis).

What is and is not covered
How to enroll — no open season required
Unlike FEHB or FEGLI, the transit benefit has no open-season restriction. You can enroll, update, or cancel any time your commuting situation changes. The benefit is retroactive only to your enrollment date — delay costs real money.
