According to an informational web page on the IRS's web site, when they conduct an audit, they will ask for a specific document and (presumably) ask specific questions relating to that document.
Can I expect an audit to stick to specific questions about specific documents about which I have been notified ahead of time, or can an audit veer off into uncharted territory and become a fishing expedition? If so, am I within my rights to insist that the auditor stick to specific questions about which I have been notified beforehand?
One reason why I ask this question is that the information on the IRS web site, does not jive with other web sites that suggest the IRS asks all kinds of probing questions about matters that have nothing to do with the return.
