Funding Healthcare: The Medicare Tax Calculator

Medicare is the United States' federal health insurance program, primarily for people who are 65 or older. It is funded through a dedicated payroll tax. The Medicare Tax Calculator is a tool from salary-slip-generator.com that helps you estimate your annual contribution to this vital program. Unlike Social Security tax, Medicare tax has no income limit—it applies to all of your earnings. This calculator helps you see how much you pay, whether you're a W-2 employee or self-employed.

Furthermore, higher-income earners are subject to an "Additional Medicare Tax." Our calculator accounts for this extra tax, giving you a complete picture of your Medicare liability based on your income and filing status. For employees, it calculates your share of the tax; for the self-employed, it calculates the full self-employment portion. This estimation is essential for understanding your paycheck deductions and for accurate quarterly tax planning if you work for yourself.
