Global Income Tax Estimator
Compare tax brackets across cross-border locations.
What this calculator does
This tool provides simplified personal income tax estimates for four distinct regional structures: the US Federal bracket (10%-37%), UK Income Tax (Basic/Higher/Additional), Hong Kong Salary Tax (standard 15% rate vs progressive, whichever is lower), and Taiwan Integrated Income Tax. Input your gross annual income in numerical terms to see a direct cross-country tax burden comparison. This is extremely valuable for evaluating expat packages, digital nomad relocations, or general salary planning. Note that this covers baseline income tax elements and excludes state/local taxes or mandatory social healthcare contributions.
Formula & how it works
Progressive taxation formula: Total Tax = Sum of (Income within Bracket × Bracket Rate), less standard personal allowances.
Worked examples
- Comparing 100K annual earnings: US Federal taxes typically hover significantly higher than Hong Kong, which caps out under a standard 15% limit for most high earners.
- An 80,000 salary in the US encounters progressive federal rates yielding around 12K in base taxes, while UK equivalent brackets slice out a larger percentage of gross income.
Frequently asked questions
- Are state and local taxes included for the US?
- No, this calculator only handles baseline Federal Income Tax estimates. State taxes vary massively by location.
- Why does the Hong Kong tax system use two methods?
- Hong Kong calculates taxes using both progressive rates (2%-17%) with allowances, and a flat 15% standard rate applied to gross income without allowances, naturally charging you the lower of the two.
