What Is an IRS Audit?
Understanding the IRS Examination Process
An IRS audit is a formal examination of your tax return to verify that the information is accurate and that you've paid the correct amount of tax. The IRS uses several selection methods, including computerized scoring, information matching, related examinations, and research-based random selection. Selection alone does not mean the IRS believes you did something wrong.
During an audit, the IRS examines specific items on your return (like deductions or income sources) or conducts a comprehensive review of all items. Your CPA acts as a professional intermediary, organizing documents, communicating with the IRS, and protecting your rights throughout the process.
Types of IRS Audits
How correspondence, office, and field examinations differ
The format determines where the examination happens, how broad the document request may be, and how much direct contact you have with the IRS. Start by identifying the audit type named in the notice.
| Factor | Correspondence audit | Office audit | Field audit |
|---|---|---|---|
| Complexity | Low — mail-only questions | Medium — in-person at IRS office | High — on-site at your business/home |
| Duration | 30-90 days | 2-6 months | 6-12+ months |
| Scope | Specific line items (deductions, credits) | Multiple years or issues | Comprehensive (all records, ledgers, bank statements) |
| Records Required | Copies mailed or electronically submitted | Original documents to IRS office | Full access to books, records, and premises |
| Taxpayer Stress | Low | Medium | High |
These are planning averages, not deadlines. Short staffing and case backlogs at the IRS have lengthened turnaround times, so correspondence, office, and field audits may take longer than the ranges shown.
What Triggers an Audit?
Common Risk Factors and Selection Criteria
The IRS uses multiple selection methods to identify returns for audit. Understanding these factors helps you understand your audit risk and prepare accordingly.
High-Income Returns
Higher incomes increase audit probability. The IRS dedicates resources to reviewing returns above certain thresholds ($500K+).
Self-Employment Income
1099 contractors and business owners face higher audit rates than W-2 employees. The IRS focuses on income reporting accuracy.
Large Deductions
Home office, business meal, and charity deductions that are disproportionately large relative to income trigger scrutiny.
Unusual or Aggressive Positions
Hobby loss claims, large net operating losses, or novel tax strategies increase audit risk.
Prior Audit History
A history of audits or prior issues increases future audit likelihood, especially in the same areas.
Cash-Heavy Businesses
Restaurants, retail, and service businesses with significant cash revenue face higher audit rates.
Your Rights During an Audit
The Taxpayer Bill of Rights Protects You
The IRS Taxpayer Bill of Rights (10 core rights) protects you during an audit. Understanding these rights empowers you to advocate for yourself and work effectively with your CPA.
Right to Know
You have the right to know why you're being audited, what laws apply, and what you're expected to pay.
Right to Representation
You can be represented by a CPA, attorney, or other qualified professional. You don't have to meet with the IRS alone.
Right to Appeal
If you disagree with IRS findings, you have the right to an independent appeals hearing before paying additional taxes.
Right to Confidentiality
The IRS must protect your privacy and can only disclose tax information with your consent or as required by law.
Right to a Clear Explanation
The IRS must provide a clear written explanation of any changes to your return and your appeal rights.
Step-by-Step Audit Process
What to Expect When You're Audited
Understanding the audit timeline helps you stay calm and organized. Here's what typically happens:
Audit Notice Received
You receive an IRS letter (Notice 556 or similar) explaining which return is being audited, which items are being examined, and what documentation is requested.
Contact Your CPA Immediately
Don't respond directly to the IRS. Contact your CPA to verify the notice is legitimate, discuss audit scope, and develop a response strategy.
Gather Documentation
Your CPA helps you organize all relevant documents (bank statements, receipts, invoices, ledgers, logs) to support your tax positions.
Request Extension If Needed
If you need more time, your CPA can request a 30-day extension (or negotiate for more time) to avoid rushing documentation.
Prepare Response
Your CPA drafts a detailed response explaining your positions, citing tax law, and submitting supporting documentation in organized folders.
Submit to IRS
Your CPA submits the response on time, often via electronic upload or certified mail to ensure delivery proof.
IRS Responds
The IRS examines your documentation and either accepts your positions (closes the case) or proposes changes and schedules a meeting or calls your CPA.
Negotiation or Appeal
If the IRS proposes changes, your CPA negotiates or requests an independent appeals hearing if you disagree with the findings.
Final Resolution
The case closes with either no changes (full success), agreed adjustments, or escalation to appeals/Tax Court if unresolved.

Common Audit Pitfalls to Avoid
Mistakes That Expand Audits and Create Liability
Many taxpayers inadvertently make mistakes during audits that expand the scope or create additional liability. Here's what to avoid:
Responding Without Professional Help
Many taxpayers write their own responses or make verbal statements that concede ground or misstate tax law. Always have a CPA or attorney review your response.
Volunteering Information
If the IRS asks about specific items, answer only those questions. Volunteering information about other years or issues can expand the audit scope.
Missing Deadlines
Failure to respond by the IRS deadline can result in default assessments (IRS assumes you owe the full proposed adjustment). Request an extension if needed.
Disorganized Documentation
Submitting a chaotic pile of receipts and invoices looks unprofessional and invites deeper scrutiny. Organize documents by category and provide a detailed index.
Arguing with Auditors
Personal friction with IRS auditors can escalate the audit. Let your CPA handle all interactions and negotiations professionally.
Admitting Errors You're Unsure About
If the IRS proposes changes, don't immediately agree. Your CPA can request time to analyze the position and determine whether to agree, dispute, or appeal.
Ignoring the Audit Notice
Failure to respond is treated as agreement. Even if you think the notice is wrong, respond (through your CPA). Ignoring it locks in the IRS's proposed changes.
