IRS audit defense is professional representation during an Internal Revenue Service examination of a tax return. The IRS conducts three types of audits: correspondence audits (by mail, accounting for approximately 75% of all audits), office audits (at an IRS office), and field audits (at the taxpayer's home or business, the most comprehensive). In fiscal year 2023, the IRS audited approximately 0.4% of all individual returns, but audit rates increase significantly for higher-income taxpayers and certain industries.
What Is IRS Audit Defense?
Audit defense means having a qualified representative handle every aspect of an IRS examination on your behalf. Under Form 2848 (Power of Attorney), your representative receives all IRS correspondence, responds to document requests, attends meetings, and negotiates adjustments. You do not need to speak with the IRS directly or attend any audit sessions. According to the IRS, correspondence audits are the most common type and can often be resolved by providing specific documentation the IRS requests.
Office audits require an in-person meeting at an IRS office and typically involve more complex issues such as business income, rental property, or itemized deductions. Field audits are conducted by IRS revenue agents at the taxpayer's location and involve the most thorough examination of records. Field audits are reserved for complex returns, high-income individuals, and situations where the IRS suspects significant underreporting.
What Triggers an IRS Audit?
The IRS uses several methods to select returns for examination. Understanding these triggers helps contextualize why you received an audit notice.
What Are Your Rights During an IRS Audit?
The Taxpayer Bill of Rights, codified in IRC § 7803(a)(3), guarantees fundamental protections during an audit. You have the right to be informed about what the IRS is doing and why. You have the right to quality service and to pay no more than the correct amount of tax. You have the right to challenge the IRS's position and be heard. You have the right to appeal IRS decisions in an independent forum. And critically, you have the right to representation: you can authorize a qualified professional to represent you before the IRS at any point during the process.
The IRS must also follow specific procedural rules during an audit. The examiner must explain the audit process, identify the items being examined, allow reasonable time to gather documentation, and provide a written explanation of any proposed changes. If the examiner requests documents beyond the scope of the original audit notice, your representative can challenge the expansion.
How to Respond to an IRS Audit Notice
- 1Do not ignore the noticeFailing to respond to an audit notice results in the IRS making changes to your return based solely on its own calculations, which are almost always unfavorable to you.
- 2Review the notice carefullyIdentify the specific items being examined, the tax year in question, and the response deadline. The notice will specify what documentation the IRS is requesting.
- 3Gather documentationCollect all records that support the items being audited: receipts, bank statements, contracts, mileage logs, and any other substantiation. Organization matters.
- 4Consider professional representationFor correspondence audits involving simple issues, you may respond on your own. For office or field audits, or any audit involving business income, professional representation is strongly recommended.
- 5Respond within the deadlineAudit notices specify a response date, typically 30 days. If you need more time, contact the IRS or have your representative request an extension before the deadline passes.
What Happens If You Disagree with Audit Results?
After the audit, the IRS issues a 30-day letter with proposed changes and the additional tax, penalties, and interest it believes you owe. You have 30 days to request a conference with the IRS Independent Office of Appeals. The Appeals process is an informal administrative hearing where many disputes are resolved through negotiation. If you do not request Appeals within 30 days, or if Appeals does not resolve the dispute, the IRS issues a 90-day letter (formally called a Notice of Deficiency under IRC § 6212).
The 90-day letter gives you 90 days to petition the United States Tax Court. Tax Court allows you to dispute the IRS's determination without paying the assessed amount first. If you do not petition Tax Court within 90 days, the assessment becomes final and the IRS can begin collection.
