How to Handle an IRS Audit: A Step-by-Step Guide from a US CPA
Receiving an IRS audit notice is one of the most stressful experiences a taxpayer or business owner can face. However, with the right knowledge and professional representation, most IRS audits can be resolved successfully — often with little or no additional tax liability. This guide, written from the perspective of an experienced US CPA, walks you through exactly what to expect from the IRS audit process and how to protect yourself at every step.
Understanding the Different Types of IRS Audits
Correspondence Audit
The most common type of IRS audit is conducted entirely by mail. The IRS sends a letter requesting documentation to support a specific item on your tax return — commonly a charitable deduction, business expense, or income discrepancy. Correspondence audits are generally the least severe and can often be resolved quickly by submitting the requested documentation with a clear written response.
Office Audit
An office audit requires the taxpayer to appear in person at a local IRS office to answer questions and present documentation. These audits are more comprehensive than correspondence audits and typically involve a more complex tax return or a higher-risk deduction pattern. Having a CPA or enrolled agent accompany you to an office audit is strongly recommended.
Field Audit
A field audit is the most thorough and intensive type. An IRS revenue agent visits your home or place of business to examine your records, interview you, and review your financial operations. Field audits are typically reserved for complex business returns, high-income earners, and cases where the IRS suspects significant underreporting. Professional CPA representation is essential in a field audit.
What Triggers an IRS Audit?
The IRS uses a combination of computer scoring (DIF scores), document matching, and manual review to select returns for audit. The most common audit triggers include: unusually high deductions relative to income, home office deductions on Schedule C, large charitable deductions without proper documentation, net operating losses in multiple consecutive years, high cash business income, and cryptocurrency transactions. High-income earners and sole proprietors face statistically higher audit rates than W-2 employees.
Your Rights During an IRS Audit
Every taxpayer has rights during an IRS examination, outlined in the Taxpayer Bill of Rights. You have the right to professional representation — by a CPA, enrolled agent, or tax attorney — and you have the right to have your representative speak on your behalf without you being present. You have the right to appeal IRS decisions, and you have the right to receive fair and professional treatment from IRS examiners.

Step-by-Step: What to Do When You Receive an IRS Notice
Step 1: Read the Notice Carefully
Do not panic. Read the IRS notice from beginning to end and identify: (a) what type of notice it is, (b) what specific items are being questioned, (c) what the deadline for response is, and (d) whether you owe money or simply need to provide documentation. Different notices require different responses, and responding to the wrong issue or missing a deadline can create additional problems.
Step 2: Contact a CPA Immediately
Before you respond to the IRS — in writing or otherwise — consult with a licensed CPA or enrolled agent. An experienced tax professional can assess the notice, identify the risk level, determine the best response strategy, and communicate with the IRS on your behalf. Do not attempt to handle a field audit or a large proposed deficiency without professional representation.
Step 3: Gather and Organize Documentation
Work with your CPA to compile all records relevant to the questioned items: bank statements, receipts, cancelled checks, credit card statements, mileage logs, contemporaneous records of charitable contributions, business contracts, and payroll records. The IRS places the burden of proof on the taxpayer, so thorough documentation is your most powerful defense.
Step 4: Respond Within the Deadline
IRS notices always include a response deadline. Failing to respond within this period can result in automatic assessment of the proposed deficiency plus penalties and interest. If you need more time to gather documentation, your CPA can request an extension of the response period.
Step 5: Appeal If Necessary
If the IRS proposes adjustments you disagree with after the audit, you have the right to appeal through the IRS Independent Office of Appeals. A CPA or tax attorney can prepare a written protest and represent you at the appeals conference. The IRS Appeals process resolves a large percentage of disputed cases without going to Tax Court.
Preventing Future Audits: Best Practices
The best audit defense is a strong offense: accurate, well-documented, professionally prepared tax returns. Maintain organized records throughout the year, reconcile business bank accounts monthly, use accounting software, and work with a CPA who reviews your return for red flags before filing. Year-round tax planning with a qualified CPA firm also reduces the likelihood of large, unexplained fluctuations in your returns that attract IRS attention.
