text:  In March of this year, the IRS announced a new voluntary disclosure program. The idea there was to allow scammers or businesses that had improperly claimed the tax credit to come forward, and they would be allowed to keep 20% of what they got if they returned the rest. The program has already recovered about $2 billion, which is nothing to sneeze at, but I think that indicates that there's a huge amount of unrecovered fraud out there, and we may never get a final accounting of exactly how much this program lost.
