Identify the examination and protect the response date
The IRS begins an audit by mail. The first review preserves the complete notice and envelope, confirms that the communication is authentic, and identifies the form, tax year or quarter, items under review, response method, and due date. A request involving one deduction or credit should not be treated as though the entire return has automatically been challenged.
Deadlines are notice-specific. Some preliminary examination letters provide a limited period to request an administrative appeal, while a statutory notice of deficiency generally gives 90 days to petition the United States Tax Court, or 150 days when addressed to a person outside the United States. The IRS cannot extend the Tax Court filing deadline. The actual notice should be reviewed promptly, with legal counsel involved when court rights or legal strategy are at stake.
- Keep every page of the notice, its attachments, response forms, and the envelope
- Locate the filed return and amendments for every period identified
- Gather prior IRS correspondence, payment confirmations, and available transcripts
- Record the response date, delivery method, IRS contact, and any scheduled meeting
