IRS Survey

A survey performed for the IRS with 2200 people discovered: 23% admitted cheating by either underreporting income or overstating deductions. 52% think at least one in four of their fellow taxpayers is cheating too, and that cheating is becoming more prevalent. 63% say it is fear of getting caught that keeps people from cheating.
