- Section 125 cafeteria-plan health premiums reduce federal, state, AND FICA wages — uniquely powerful.
- Dependent-care FSA up to $5,000/year (federal-side savings).
- Pre-tax commuter benefits for transit and parking.
- HSA contributions if you're on a high-deductible health plan (federal-only — California doesn't conform).
