What about Cuba?Fatca is for US citzens who get reported only to the IRS. While FATCA wont apply in your case, unfortuntately Switzerland will report to Brazil via CRS.
Also, I took a look at the oecd.org website and see that Swiss and Brazil has no activated exchange relationship.
Or that doesn't matter?
OKay, great.If that is the case then i am wrong but switzerland has agreements with many countries given the historical nature of swiss bank accounts. As you did it is best to check oecd website for latest
