How it works›

Payroll taxes. Compares capped Social Security wages before and after the eligible contribution, using the selected year's SSA wage base. Medicare includes the 0.9% additional tax above the filing-status threshold. Entered wages are assumed to be the household's only Medicare wages; other employers, spouse wages and self-employment income can change the result.

Scope and sources. Qualified healthcare FSA salary reduction under IRS Publication 15-B. Federal income-tax savings use the standard deduction and no other adjustments or credits; state taxes are excluded. Sources: IRS Publication 15-B and the SSA contribution and benefit base table.
