Tech workers face a distinctive tax challenge: base salary is just one component. RSUs (Restricted Stock Units), stock options (ISOs and NSOs), and annual bonuses all have different tax treatment depending on jurisdiction — and the differences are enormous. A tech worker earning $200,000 base + $100,000 in RSUs can take home $230,000 in Singapore vs $175,000 in California — a $55,000 difference, purely from tax structure.
This guide compares the most popular tech hub countries by total effective tax rate on a combined salary + equity compensation package, covering RSU vesting, option exercise events, and exit liquidity scenarios.
How much do you keep from a $100,000 RSU vest in different locations?
| Location | Tax on $100K RSU | Keep |
|---|---|---|
| UAE (Dubai) | $0 | $100,000 |
| Singapore (EP holder) | ~$18,000 | $82,000 |
| Netherlands (30% ruling, €) | ~$21,000 | $79,000 |
| UK (higher rate taxpayer) | ~$40,000 | $60,000 |
| Germany (high earner) | ~$47,500 | $52,500 |
| California (federal + state) | ~$47,000–50,000 | $50,000–53,000 |
| France (high earner) | ~$54,000 | $46,000 |
The gap is enormous: UAE saves $47,000 vs California on a single $100,000 RSU vest. Over a 4-year standard vesting schedule at this level, the cumulative difference is $188,000.
