@Fkokash
(a) which country is the property in ? Did you pay any taxes on the sale of the house ?
(b) Are you a US person ( citizen/GreenCard/ Resident for Tax purposes ) or were at the time of the sale of the property ?
(c) How did you acquire the property ? How did you use it ?
In general, reporting of sale a house , whether domestic or foreign is exactly the same. The only difference is that you have recognize all transactions in US$ of the day.
Please answer my questions and I will circle back and walk you through on how to report ( and be taxed on) the transaction.
Is there more I can do for you ?
