The I-R-S Oversight Board says more Americans feel it's their duty to turn in anyone who cheats on their taxes.
The board provides independent oversight and advice to the I-R-S. It says a survey found more than three out of five people believe neighbors who cheat on taxes should be reported. That's up from about 53 percent a year ago.
The board's chairman says stories of corporate corruption and law firms that work out illegal tax shelters for rich clients could be spurring the trend toward the new attitude.
The survey found that about 88 percent say it's "not at all" acceptable to cheat on taxes, up slightly from a year ago.
