Americans may make plenty of jokes about cheating on their taxes, but a new survey finds that in reality most don't think it's OK to rob the tax man. Or at least, that's what they're telling the IRS Oversight Board.

The 2012 Taxpayer Attitude Survey, released Tuesday by the independent oversight board, finds that 87 percent of Americans don't think it's OK to cheat on your taxes. That's a three percentage point increase from last year.
