Do I pay taxes for bank account?

I might receive money as a gift due to a land sold in another country. I am talking about 10 to 15 thousand dollars. Do I or the bank have to inform the US about it? By the way, most likely would be via bank transfer.

If it's more than $12,000, you'd need to file an IRS Form 3520 declaring the amount of money received and brought into the US.

Wait--something is unclear. Are you receiving the land as a gift, then selling it for cash?

Or is someone who currently owns the land selling it, then giving proceeds from the sale to you as a gift?

The tax treatment of the money depends on which of those two things is what is really going on.
