Understanding “Medicare” style healthcare payroll taxes globally

Many countries fund parts of public healthcare with payroll taxes: a base rate on earnings and, in some systems, a high‑income surcharge above a threshold. A well‑known example is the U.S. Medicare structure, where the standard employee rate is 1.45% (also 1.45% for employers), and high earners pay an additional 0.9% on income above a set threshold.

While names and exact rules vary around the world, the logic is similar: determine taxable earnings, apply the base rate(s), then apply any surcharge to the portion above the threshold. This calculator lets you customize rates and thresholds for flexibility while keeping the experience simple and accessible for students, professionals, and curious learners.

Key ideas at a glance

  • Base rate: The primary percentage applied to wages and, if relevant, self‑employment income.
  • Employer vs employee share: Many systems split contributions — self‑employed may owe both portions.
  • High‑income surcharge: An extra percentage on income exceeding a threshold (often employee‑only in some systems).
  • No wage cap: Some systems have no ceiling for the healthcare portion (e.g., Medicare base has none).

Worked example (using the example defaults)

Suppose total annual wages are 220,000 and self‑employment income is 0. With a 1.45% base employee rate, 1.45% employer rate, and a 0.9% surcharge above 200,000 paid by the employee, you’d apply the base to all wages and the surcharge to the 20,000 above the threshold.

FAQs

HOW TO set my country’s rates?

Switch Preset to “Custom,” then enter your base employee and employer rates, surcharge rate, and threshold. If you’re self‑employed and your country requires both portions, set “Self‑employed pays both portions?” to Yes.

HOW TO treat high‑income surcharge correctly?

Enter the threshold and surcharge rate. If your system applies the surcharge only to employee/self‑employed, choose “Employee/self‑employed only.” If both parties share it, choose “Both.”

HOW TO estimate U.S.‑style Medicare using this tool?

Use the example defaults (1.45% base for employee and employer, 0.9% surcharge above the threshold paid by the employee) — these mirror the well‑known U.S. Medicare structure.

HOW TO understand the chart percentages?

The doughnut shows the share of each component (employee, employer, self‑employment, surcharge) as a percentage of the total tax.

HOW TO handle multiple jobs or currencies?

Sum your earnings for the year and choose the currency symbol you prefer. The calculation logic is currency‑agnostic.
