A tax audit is not pleasant, especially considering that ninety percent of audits result in the taxpayer owing money.    Being represented by a tax attorney at the audit will not guarantee that you will not owe money at the end of the process.  The attorney will try to limit the scope of the audit, and will insure that the information presented is well organized and will limit the response of the taxpayer to meet the concerns of the auditor.  An experienced attorney can establish the facts of reasonable cause to eliminate penalties, which can be significant.  At the Law Office of Arthur Weiss, we appear for you (you may be present but it is generally not required) at the audit, indeed, in many cases the audit is performed in our offices.
