I had my CPA research the tax law concerning currency. This is what he told me. Since my largest purchase was not in 2013, but actually 10 years ago, my taxes would be 20%. Any Dinar purchased in 2013 would have to pay the larger rate which I believe is 37%. So if you purchased prior to 2013, you will pay less funds.
I have also heard that the Treasury Dept. has stated that there are no takes on currency, but that Congress is concerning a 2 or 3% taxes.
Last, I contacted my Congressman and ask them to give me an accurate amount I might owe in Federal Taxes. As of this date I have not received word yet. But his staff said they would research it an get back to me.
