Practical Suggestions for Effectively Representing a Taxpayer in an IRS Examination... [ read ]
Through the years we have developed, or adopted from other practitioners, suggestions about dealing with the IRS in exams. The suggestions below are generalizations, to which there are substantial exceptions. Practitioners that deal with the IRS are bound not only by their individual professional ethics but also by Circular 230. It is important to recognize the significance and import of those rules and to apply not only their letter but also their spirit. The goal of any representative is to get a client out of an IRS examination as quickly as possible.
