What is Medicare Tax?
Medicare tax is part of FICA (Federal Insurance Contributions Act) taxes and funds the Medicare hospital insurance program. Unlike Social Security tax, there is no income limit on Medicare tax—all of your earned income is subject to it.
Medicare Tax Rates
- Standard Rate: 1.45% for employees (employers match this).
- Additional Medicare Tax: An extra 0.9% tax applies to income above certain thresholds ($200,000 for Single filers, $250,000 for Married Filing Jointly).
Self-employed individuals pay the full 2.9% standard rate plus the additional 0.9% if they exceed the income threshold.
