Receiving an IRS Letter 566 means the IRS has initiated a correspondence audit of your tax return. This type of audit is conducted by mail and requests documentation to verify specific items on your return.

🚨 What Letter 566 Means
- Letter 566 is a correspondence audit letter.
- It indicates that the IRS is reviewing your tax return and needs additional documentation.
- The IRS will specify which records you must provide (e.g., receipts, bank statements, proof of deductions).
- You must submit the requested records by the due date to avoid adjustments or penalties.
🎯 Purpose of Letter 566
The purpose of Letter 566 is to:
- Verify the accuracy of your tax return.
- Request supporting documentation for deductions, credits, or income reported.
- Allow you to respond by mail rather than attending an in‑person audit.
⚖️ What the Taxpayer Should Do
- Read the letter carefully: Identify which items are under review.
- Gather documentation: Collect receipts, statements, or other records requested.
- Submit records on time: Mail or fax the documents by the due date listed.
- Keep copies: Retain copies of everything you send to the IRS.
- Seek representation: Contact CPA Clinics or a tax professional for guidance.
⚠️ Common Complications
- Missed Deadline: Failing to respond can result in disallowed deductions or added tax.
- Incomplete Records: Missing documentation may lead to unfavorable adjustments.
- Financial Burden: Adjustments can increase your tax liability significantly.
- Language Barriers: ESL taxpayers may struggle to understand the notice and requirements.
