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.

Get Paid Compliantly as a Global Tech Worker →In Singapore, RSUs are taxed as employment income at the time of vesting — the market value of the shares on the vesting date is treated as ordinary income and taxed at Singapore's progressive income tax rates (0–22%). Once vested, any subsequent appreciation in the share price is completely tax-free (Singapore has no capital gains tax). For example: if you receive 1,000 shares vesting at $50/share ($50,000 vest value), you pay Singapore income tax on $50,000. If the share price rises to $200 by the time you sell, the $150,000 gain is completely tax-free. This is why high-income tech workers, particularly those with significant equity exposure, often prefer Singapore to California or the UK.
Yes — the 30% ruling remains available in 2026, though the Dutch government has made changes. The ruling allows qualifying expat employees to receive 30% of their salary as a tax-free expense reimbursement, effectively reducing the taxable portion of salary. Key 2024 changes: the ruling was capped (the 30% benefit applies only to the first €233,000 of salary in 2024); the duration was previously being reduced to 5 years (from 8) but a 5-year period is now the standard. Qualifying criteria: must be recruited from abroad, have specialized expertise not available in the Netherlands, and have lived more than 150km from the Dutch border for at least 16 of the 24 months before starting Dutch employment. Minimum salary threshold applies (€46,107 for most workers in 2024; lower for scientific researchers under 30).
Yes — significantly. RSUs typically vest as income automatically; options give the right to buy shares at a strike price. Most countries treat option exercise (buying shares at strike price when current value is higher) as ordinary income taxable at exercise. Some countries have preferential option regimes: UK EMI options (10% Business Asset Disposal Relief CGT on qualifying option gains); US Incentive Stock Options (ISO) can trigger AMT but get long-term capital gains rates if held correctly; France has qualifying stock option plans with a 12.8% PFU flat tax on gains; Germany taxes options at exercise at ordinary income rates but subsequent gains at 25% Abgeltungsteuer. Country-specific guidance from a cross-border tax professional is essential if you're holding significant unvested equity before relocating.
For senior tech workers earning $150,000–300,000+: yes, typically. The tax saving vs California, UK, or Germany at these income levels is $40,000–80,000/year. Dubai's cost of living (housing $3,000–5,000/month, schools $15,000–30,000/year) reduces but does not eliminate this advantage. The main non-financial trade-offs: Dubai doesn't have the startup culture of San Francisco or London; the tech ecosystem is smaller and primarily focused on regional businesses; professional networks are less dense; and the social environment is different from Western tech hubs. For pure maximization of after-tax income, especially for engineers with Bay Area or London packages, Dubai is compelling. The financial argument weakens at salaries below $120,000 where Dubai's cost-of-living premium starts to offset the tax saving.
For founders who build and eventually sell: Singapore is typically optimal. Reasons: (1) 0% CGT on shares — the proceeds from selling your company shares are completely tax-free; (2) Singapore's holding company structure for subsidiaries operating elsewhere is well-established; (3) Singapore has an extensive treaty network; (4) Exit structuring is straightforward under Singapore law. UAE is also 0% CGT but has less developed corporate law and M&A ecosystem. UK Business Asset Disposal Relief (10% CGT on first £1M) is excellent for smaller exits. Ireland's Entrepreneur Relief (10% on first €3M) is good for medium exits. US founders face federal long-term CGT of 20% + state tax — moving to Nevada or Florida eliminates state CGT but federal remains. For very large exits ($50M+): proper advance tax planning with a specialized international tax attorney is essential regardless of jurisdiction.
