Therein lies the problem. Are we going to go after businesses, purely on the say-so of another person? Audits cost money. They cost the government money and they cost the citizens money. What will we create, when Joe the Grocer is fingered by who-the-hell-ever as a tax cheat, gets audited and is found to have perfect taxes? The government spent money for nothing and Joe the Grocer was forced to spend money for nothing, on the word of who-the-hell-ever. At the end of the day, Joe has a nice, fat, juicy lawsuit against the government and the clown that invaded his privacy and wrongfully accused him of tax evasion; again, costing more money.As far as the cost being more than their gains - collecting tax is nothing new to the IRS or the states. The concept of cost/benefit is not lost upon them. They're clearly not going to conduct massive audits of everyone reported through this program. Rather, they would focus their efforts where they expect the greatest payout. This just helps them identify that easier.
The $64,000 is: will the effort be worth the return? IMO, there's no way.
