Receiving an audit notification from the IRS or a state tax authority is one of those experiences that business owners universally dread. The envelope arrives, the heart rate increases, and the imagination produces worst-case scenarios. The reality is typically less dramatic. Most business audits are focused examinations of specific items, and the outcome depends far more on preparation and presentation than on the underlying facts. Understanding the Types of Audits Not all audits are created equal. The IRS conducts three primary types of examinations, each with different scopes and procedures. A correspondence audit is the most common and least intrusive. The IRS identifies a specific item on your return that needs clarification or documentation and requests that you mail the supporting information. Common triggers include unusual deductions, discrepancies between reported income and information returns (1099s and W-2s), and home office deductions. An office audit requires you (or your representative) to visit an IRS office with specified records. These examinations are typically broader than correspondence audits and may cover multiple items on the return. The IRS will provide a list of documents to bring. A field audit is the most comprehensive. An IRS revenue agent visits your place of business to examine your books and records on-site. Field audits are typically reserved for businesses with complex transactions, high gross receipts, or returns that raise multiple questions. Assembling Your Records The foundation of any successful audit response is complete and organized documentation. When the audit notice arrives, the first step is to identify exactly which items are under examination and gather all supporting records. For business expenses, this means receipts, invoices, cancelled checks, credit card statements, and contemporaneous records explaining the business purpose of each expenditure. For vehicle expenses, mileage logs documenting the date, destination, business purpose, and miles driven for each trip. For meals and entertainment, records showing the date, location, attendees, business purpose, and amount of each expense. For income, gather all bank statements, deposit records, and source documents. The IRS frequently compares total bank deposits to reported income, and any unexplained deposits will be treated as unreported income unless you can demonstrate otherwise. The Role of Your Accountant and Attorney You have the right to be represented by a qualified professional during an audit. A CPA, enrolled agent, or tax attorney can communicate with the IRS on your behalf, attend meetings, and present your case. Many business owners find that professional representation reduces both the stress and the final assessment. Your accountant brings knowledge of how the return was prepared and can explain the tax positions taken. Your attorney brings knowledge of your rights during the examination, the standards of proof that apply, and the appeal and settlement processes available if you disagree with the examiner's findings. For routine correspondence audits, your accountant alone is typically sufficient. For office and field audits, having both your accountant and an attorney involved is prudent, particularly if the audit involves complex transactions, potential penalties, or amounts that are material to the business. During the Audit Several principles apply during any audit examination. Provide exactly what is requested, nothing more and nothing less. Volunteering information beyond what is asked can open new areas of inquiry that were not originally part of the examination. Answer questions truthfully but concisely. If you do not know the answer, say so rather than speculating. Keep the examination in a controlled environment. If the audit is a field examination at your place of business, designate a conference room for the auditor's use. Do not allow the auditor to wander through the office, interview employees, or access records beyond those relevant to the examination. Maintain a professional and cooperative demeanor. Revenue agents are professionals doing their job, and a confrontational approach is counterproductive. At the same time, be aware of your rights. You have the right to know why the IRS is asking for information, the right to know how it will be used, and the right to disagree with the examiner's conclusions. Common Audit Triggers for Businesses Understanding what triggers audits can help you maintain records that will withstand scrutiny. High deduction-to-income ratios attract attention. Significant cash transactions without adequate documentation raise questions. Classifying workers as independent contractors when the IRS believes they should be employees is one of the most common and most consequential audit issues. The reasonable compensation of S-corporation shareholders is another frequent area of examination. S-corporation owners who pay themselves minimal salaries while tak
