IRS Mail Audit
If the IRS conducts an audit by mail, the letter will request additional information about certain items shown on the tax return such as income, expenses, and itemized deductions. If you have too many books or records to mail, you can request a face-to-face audit. The IRS will provide contact information and instructions in the letter you receive.

A mail audit, also known as a correspondence audit, is conducted entirely by mail. This is the most common type of IRS audit and typically focuses on one or two simple issues. Mail audits are usually less intrusive than field or office audits.
Your first step in a mail audit is to gather documentation and determine if there are any discrepancies between your records and the information reported on the tax return. When responding to a mail audit, send sufficient documentation to support each item that the IRS is examining. At the end of the audit you will receive an audit report that details the proposed changes to the tax return. You have the right to dispute the changes if you disagree with them.
