Types of IRS Audits
The IRS conducts several types of audits, varying in complexity and intrusiveness.
Correspondence Audit (Mail Audit)
The most common and least invasive type. The IRS sends a letter requesting:
- Documentation for specific items
- Explanation of certain deductions
- Verification of income or credits
Office Audit
You are asked to bring records to an IRS office. Typically focuses on:
- More complex issues than mail audits
- Multiple items or tax years
- Cases requiring in-person review
Field Audit
An IRS agent comes to your home or business. Reserved for:
- Large and complex returns
- Business audits
- High-income taxpayers
- Suspected fraud
Why Returns Get Selected
- Random selection - Statistical sampling
- Document matching - Discrepancies between reported and third-party info (W-2s, 1099s)
- Related examinations - Your return relates to audited business partners
- High deductions - Unusually large deductions relative to income
- Triggers - Certain items that frequently involve errors
