Your marginal tax rate — the rate applied to your next earned dollar — is 17.0% in Hong Kong and 40.0% in United Kingdom.

Important caveats

- 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).
