The CSU Pre-Tax Parking Deduction Plan allows eligible employees to pay for CSU parking expenses with pre-tax dollars. This pre-tax benefit is available only through payroll deduction for qualified parking as defined by the IRS and established by our campus. For an eligible employee, participation in the Plan is automatic unless you choose otherwise. Deductions are taken from your pay before federal, state, Social Security, and Medicare taxes are calculated. An employee's taxable income is reduced, and consequently taxable income reflected on an employee's W-2 statement is reduced.
