I'm a US citizen and inherited foreign property outside the US after my father passed away. My father was a US citizen as well. The property consists of a vacant land worth $1 million, and a house worth $56,000. Do I need to file any forms when I file my 2015 tax return?
No, you would not have to report it on your return. It should have been included with your father's estate return.
You would only need to report foreign accounts (cash, etc) as per the instructions in the below FAQ on Report on Foreign Bank and Financial Accounts:
There was never an Estate return filed for my father after he passed away. Does that have any implications? Also, what is form 3520 and does it apply in this case?
