Note: The IRS randomly reviews a small percentage of returns regardless of audit risk. Additionally, the IRS's focus on audit risk factors changes periodically and is not made public. As a result, a low reading is no guarantee you won't be audited, nor does a high reading necessarily mean that you will be audited.
