The IRS has announced that it will begin sending letters to holders of various forms of cryptocurrency informing those taxpayers of potential misreporting (or failure to report) on virtual currency transactions. The IRS advises taxpayers who receive such a letter to review past tax filings to uncover any errors or underreporting, and amend those returns in order to pay back taxes, interest and penalties as soon as possible. These letters are part of a larger campaign designed by the IRS to crack down on misreporting or underreporting of virtual currency transactions, which are currently taxed according to the rules governing transactions in property.
