Important caveats

  • Uses national income tax + federal social security only. Sub- national taxes (US state, Canadian provincial, Swiss cantonal, German church tax, etc.) can add 2–12 percentage points.
  • Assumes single filer with no dependents, no special credits or deductions. Real-world tax bills vary significantly based on family status, housing, and region.
  • FX rates are April 2026 snapshots. Day-to-day FX volatility affects USD-equivalent conversions.
  • Cost-of-living data is Numbeo 2026, crowd-sourced and urban- skewed. Rural and non-capital-city costs can differ materially.
  • Does not include employer-provided benefits (health insurance, retirement match, paid leave, which vary dramatically between these two countries).
