Tax on inherited property sold abroad
My wife (a US citizen) inherited 3 acreas of land in Honduras. She recently sold it for $100,000. To date she has only received a down payment of $20,000 of which she had to pay a capital $4000 capital gains tax to Honduras based on the total sales price.
The purchaser has run into some legal complications (corrupt government) and is currently withholding an monthly payments.
Does she have to pay income taxes on inherited property and would it be on the full amount even though she may never receive any remaining installments?
Thanks
