Summary

Your HSA and FSA contributions save you $1,779 in taxes, including $459 in FICA taxes that most other deductions cannot reduce.

HSA and FSA contributions are pre-tax, reducing both income tax and FICA taxes (7.65%). This double tax benefit makes them one of the most tax-efficient savings vehicles.

Your FICA savings of $459 are unique to payroll deductions. Traditional IRA contributions, by contrast, only save on income tax.

FSA funds generally must be used within the plan year (use-it-or-lose-it), though employers may offer a $640 rollover or 2.5-month grace period. HSA funds roll over indefinitely.
