Pre-tax payroll deduction

A deduction from wages taken before income tax (and sometimes FICA) is calculated, reducing taxable income.

Definition

Pre-tax deductions reduce the wage amount subject to taxation. Most common: Section 125 cafeteria plan elections (health, dental, vision premiums; FSA contributions), 401(k) traditional contributions, HSA contributions, qualified transportation fringe benefits.

For employees, pre-tax deductions reduce both federal income tax and (for most categories) FICA wage base — saving roughly 25-35% of the deduction amount depending on bracket. Employers also save the FICA employer match on the reduced wage base.
