The IRS CP49 is a correspondence audit notification that signals the IRS has selected your tax return for closer examination. Unlike more severe audit notices, the CP49 usually requests specific documents or explanations to clarify portions of your tax return. Understanding how to manage this notice can help ease the audit process and reduce stress.
Each year, the IRS audits a small fraction of returns to ensure tax compliance and accuracy. The CP49 letter is a way the IRS communicates the audit initiation, typically focusing on particular income items, deductions, or credits that need verification. It does not imply wrongdoing but rather that the IRS needs further proof or explanation.
How the IRS CP49 Audit Works
-
Receiving the Letter: The IRS sends the CP49 by U.S. mail to the address provided on your tax return. The letter clearly outlines the tax year under review and details the specific items or discrepancies the IRS wants to examine.
-
Reviewing the Notice: It is essential to read the CP49 carefully, noting the exact documentation requested and the deadline for response, which is usually about 30 days from the letter date according to IRS guidelines.
-
Gathering Documentation: You should collect all relevant records such as receipts, invoices, bank statements, or proof of income that support the taxed items under question. Ensuring your records are organized will streamline the response.
-
Responding to the IRS: Follow the instructions verbatim. Most responses are sent via mail to the specified IRS address. Calling the IRS contact number on the letter for clarification is permissible and often helpful.
-
IRS Review: After receiving your documentation, the IRS will evaluate the information provided. This review will determine if adjustments are necessary or if the audit can be closed without changes.
Who Can Receive a CP49?
Any taxpayer—individual, sole proprietor, partnership, or corporation—whose tax return is selected by the IRS for a correspondence audit may receive a CP49. Common triggers include discrepancies between reported income and third-party information returns like W-2s or 1099s, unusually large deductions, or computational errors. Random selection is also possible.
Important Tips for Handling a CP49
- Stay Calm: A CP49 is a request for more information, not an accusation.
