Address Anomalies in an IRS Audit

Facing an IRS audit can be a daunting experience, especially when anomalies are discovered during the examination of your tax return. Anomalies can include discrepancies, errors, or inconsistencies in the information you’ve provided. While this situation can be stressful, it’s essential to address anomalies correctly to ensure a smooth audit process. Here, we’ll discuss how to address anomalies in an IRS audit, what to expect, and best practices for resolving these issues. 

Understand the Nature of Anomalies 

The first step in addressing anomalies in an IRS audit is to understand the nature of the anomalies. Anomalies can take various forms, including: 

  • Mathematical Errors: These are straightforward mistakes in calculations, such as addition or subtraction errors. 
  • Data Entry Errors: Errors can occur when transferring information from one document to another, leading to incorrect data on your tax return. 
  • Missing Documentation: Anomalies may arise if you’re unable to provide the required documentation to support your deductions or income. 
  • Discrepancies: These are differences between the information on your tax return and information received from third parties, such as employers, financial institutions, or clients. 

Understanding the specific nature of the anomalies will guide your response and help you address the issues effectively. 

Gather Relevant Documentation 

Once you’ve identified the anomalies, gather all relevant documentation that can help address the discrepancies. This may include: 

  • Income Documents: Collect W-2s, 1099s, and other forms that report your income from employers, clients, or financial institutions. 
  • Expense Records: Compile receipts, invoices, and records of deductible expenses that may offset your taxable income. 
  • Bank Statements: Retrieve your bank and financial statements to track financial transactions, as these can help verify your income and expenses. 
  • Previous Tax Returns: If you’ve filed tax returns in previous years, gather copies of these returns, as they can provide valuable information for resolving the anomalies. 
  • Supporting Documents: Include any additional supporting documents, such as records of charitable donations or mortgage interest, that may be relevant to your tax return. 

Having all relevant documentation organized and readily accessible will make it easier to address the anomalies during the audit. 

Consult a Tax Professional 

Addressing anomalies in an IRS audit can be complex, particularly if the issues are significant or involve legal implications. Consulting a tax professional, such as a certified public accountant (CPA) or a tax attorney, is highly advisable. These experts can provide invaluable guidance, represent you during the audit process, and ensure that you address the anomalies correctly. 

A tax professional can assist you by: 

  • Reviewing your tax returns and relevant documentation to assess the extent of the anomalies. 
  • Preparing for the audit and ensuring you have the necessary information to address the discrepancies. 
  • Communicating with the IRS on your behalf and providing explanations for the anomalies. 
  • Negotiating with the IRS to resolve the discrepancies and potentially reduce penalties or interest. 

Respond Promptly to IRS Inquiries 

During the audit, the IRS may contact you with inquiries or requests for additional information regarding the anomalies. It’s crucial to respond promptly and provide the requested information. Timely responses demonstrate your cooperation and willingness to resolve the issues. 

Be prepared to provide clear explanations and supporting documentation for the anomalies. If you need more time to gather information, contact the IRS as soon as possible to request an extension or to discuss your situation. 

Be Honest and Transparent 

Honesty and transparency are essential when addressing anomalies in an IRS audit. Provide complete and accurate information to the IRS, and avoid attempting to hide or misrepresent any aspect of your tax return. The IRS is more likely to work with you and consider your explanations if you are forthright and cooperative. 

If you made an error on your tax return, admit the mistake and provide the correct information during the audit. Honesty can go a long way in resolving discrepancies. 

Create a Reconstruction Narrative 

If the anomalies cannot be resolved with existing documentation and information, it’s essential to create a reconstruction narrative that explains the circumstances and provides a reasonable estimate or explanation for the anomalies. This narrative should include: 

  • A description of the anomalies and their significance in the audit. 
  • The efforts you made to address the anomalies, including gathering additional documentation and seeking professional guidance. 
  • Any available evidence or information that supports your explanation and helps resolve the discrepancies. 
  • An estimate or reconstruction of the missing or incorrect information based on the available data. 

The reconstruction narrative can provide context and clarity to the IRS and help in reaching a resolution. 

Request Penalty Relief 

If the IRS imposes penalties related to the anomalies, you may be eligible for penalty relief if you have reasonable cause for the discrepancies. Request penalty relief by providing supporting documentation and explanations that demonstrate your efforts to comply with tax laws and correct the anomalies. 

Consult with your tax professional to ensure that your request for penalty relief is well-prepared and stands a good chance of being approved. 

Appeal if Necessary 

In cases where the IRS and you cannot reach an agreement on the resolution of the anomalies, you have the right to appeal the IRS’s decision. You can request an appeal through the IRS Office of Appeals. A tax professional can assist you in preparing the appeal and representing your interests during the process. 

Understanding and asserting your rights during an appeal is essential to ensuring a fair and just outcome. 

Review the Audit Findings 

After the audit is complete, the IRS will provide you with its findings, which may include proposed changes to your tax return and any additional taxes, penalties, or interest owed. It’s essential to carefully review the audit results and proposed changes. 

If you agree with the findings, follow the instructions provided by the IRS for resolving the discrepancies and paying any additional taxes owed. 

If you disagree with the findings or believe that there are errors, you have the right to appeal, as mentioned earlier. Consulting with your tax professional is crucial in this stage to ensure that the appeal is prepared effectively. 

Prevent Future Anomalies 

Once the anomalies have been addressed and the audit is resolved, it’s important to take steps to prevent future discrepancies on your tax returns. This may involve improving your record-keeping practices, seeking professional advice on tax matters, and staying informed about tax laws and regulations. 

By addressing the root causes of anomalies and implementing better financial practices, you can minimize the risk of facing similar issues in the future. 


Addressing anomalies in an IRS audit can be a challenging and complex process, but by approaching it with transparency, cooperation, and the guidance of a tax professional, you can navigate it successfully. Understand the nature of the anomalies, gather relevant documentation, and respond promptly to IRS inquiries. Be honest and transparent, create a reconstruction narrative when necessary, and request penalty relief if you have a valid reason. 

Review the audit findings carefully, and take steps to prevent future anomalies by improving your record-keeping practices and staying informed about tax regulations. Ultimately, by following these steps, you can address anomalies in an IRS audit and work toward a fair and favorable resolution.
