Medicare Tax Calculator
Calculate Medicare taxes including the 0.9% additional Medicare surtax.
About This Calculator
Unlike Social Security, Medicare has no wage cap — 1.45% applies to all earned income. The Affordable Care Act added a 0.9% surtax on wages above $200,000 (single) or $250,000 (joint), which the employer is not required to match. High-earning couples may owe additional Medicare tax not withheld from paychecks.
