3. 🗺️ Optimize Your Residency
For mobile investors, where you live can drastically impact your tax bill.
| Strategy | Benefit |
|---|---|
| Move to a low-CGT country | Cut your taxes legally |
| Time your residency exit | Avoid “exit tax” on unrealized gains |
| Use treaties | Reduce withholding taxes on cross-border investments |
🧠 Example: Realize large gains while resident in Belgium or Switzerland, then relocate.
🧾 Tax-Efficient Investment Vehicles
💰 ETFs (Exchange-Traded Funds)
