@Tiquisito , just to be sure below is what I understand of the situation at hand :
(a) You a US person ( Citizen / GreenCard ) have joint US bank account ( begs the question why ? )
(b) Your mother , a Non-Resident Alien owns real estate in her home country ( which country ? ) of which she is a resident & citizen
(c) Mother sells the property in that country and plans to deposit the proceeds to the JOINT US bank account.
(d) mother files W-8 Ben ( why ? does she have US sourced income ?, does eh file yearly return--US ? )
Now the question is what are tax implications from US tax perspective?
Please could you answer my questions above , please ?
Generally all US sourced incomes for the NRA ( mother ) and world income for the citizen are taxed by the US -- taking into consideration any tax treaty between the two countries.
If the income amount is more than a trigger amount ( US$10,000 ), a SAR would be routinely raised by the US bank and generally is of no consequence. However if the incoming amount is above a max amount, there is a treasury permission required ( think it is around US$ 10 million ).
I will circle back once I hear from you .
