I have a question about holding investments on platforms like TradeUp, Interactive Brokers, and similar brokers when relocating outside my current country of residence.
If I understand correctly, these platforms allow you to keep your accounts open and continue trading, but there may be tax or legal implications depending on where you move. For someone who is not sure whether they will return to their home country, and who plans to keep long-term positions without withdrawals for the next 15–20 years, what should be considered in terms of account maintenance, taxation, and regulations?
My main concerns are:
uncertainty about future residency status
potential tax implications in both the country I’m leaving and the one I’m moving to
possible changes in broker policy (e.g., TradeUp or others might limit services to certain regions)
impact on fees, currency conversions, and reporting requirements
For reference, I’m in my early 30s, currently in a mid tax bracket, and most of my portfolio is in ETFs and blue-chip stocks. I’ve read some sources indicating that cross-border investment accounts can trigger additional reporting or withholding taxes, and I’m wondering if it might be better to restructure my holdings before moving.
