Most people pay the same rate of Medicare tax, but there are a few exceptions.
As of 2023, most workers pay a Medicare tax rate of 1.45% and the employer pays an additional 1.45%. Self-employed workers are responsible for paying the full 2.9% Medicare tax on their self-employment income.
High earners pay a bit more, in what’s called an additional Medicare tax of 0.9% above eligible wages over certain thresholds.
