Optional Form 3667 (OF 3667): Application for Pretax Transportation Fringe Benefits
Optional Form 3667 (OF 3667), Application for Pretax Transportation Fringe Benefits (Clients), is a one-page application with instructions on the back. The footer reads OPTIONAL FORM 3667 (REV. 1/2026), and the form is marked CUI when filled in. It prints no issuing agency, but its Privacy Act statement cites GSA Privacy Act System Notice GSA/-Transit-1 (Transportation Benefits Records) and its instructions name the GSA Payroll Services Branch (PSB). GSA hosts a copy in its forms library.
The instructions say the TEA-21 benefit program, a provision of 26 U.S.C. 132, is offered to employees as a pretax payroll deduction. The employee gives their name, filing date, effective month, region and agency, checks one benefit type (transportation in a commuter highway vehicle, a transit pass or qualified parking, each printed as Up to $340.00 - Monthly) or a cancellation, and signs a certification. The form notes that recertification is required by December 15th of each year, or when an employee's circumstances change.
