Medicare Tax Calculator
Calculate Medicare tax withheld, including the Additional Medicare Tax for high earners.
$
Additional Medicare tax applies to wages above $200,000 (single) / $250,000 (joint). Unlike Social Security, Medicare tax has no wage cap.
Worth Knowing
Unlike Social Security tax, Medicare tax has no wage cap — the 1.45% applies to every dollar you earn. High earners face an extra layer: an Additional Medicare Tax of 0.9% kicks in above $200,000 ($250,000 for joint filers), which employers withhold but don't match. This surtax is calculated on your return, so if you have multiple jobs, too little may be withheld and you could owe the difference at filing.
