The correct comparison is:
Employees pay half (1.45%) of the Medicare tax while the employer pays the other half. Self-employed individuals pay for both halves of the tax (2.9%).
This means that employees contribute 1.45% of their earnings to Medicare taxes, and their employer also contributes an additional 1.45%, resulting in a total of 2.9%. In contrast, self-employed individuals are responsible for paying the entire 2.9% themselves.
