Yes. Governments increasingly share financial information across borders.
Major data-sharing systems:
- CRS (Common Reporting Standard) — Over 100 countries automatically exchange financial account info annually
- FATCA (US) — Foreign banks must report American account holders to the IRS
- EU DAC — European countries share tax data automatically
- OECD agreements — Ongoing expansion of global financial transparency
What gets shared:
- Bank account balances
- Interest and dividend income
- Investment account values
- Real estate ownership (in some cases)
Why it exists:
These systems target tax evasion and money laundering. If you have accounts in multiple countries, assume each government knows about the others.
What this means for you:
- Foreign accounts are not hidden from your home country
- Crypto exchanges increasingly report to tax authorities
- “Offshore” doesn’t mean “invisible” anymore
Legal tax planning is still possible, but hiding money across borders is much harder than it used to be.
