The argument between percent of audits and money found are not in agreement. She should be asking, what percent of returns claim an EITC? If it is less than 39 percent a case may be made the EITC is being targeted. As far as 7 percent of additional taxes - is the EITC 7 percent of revenue? It may very well be the auditor is finding an error in 85-90 percent of these cases, but they are very low dollar mistakes.
