IRS Audit: What to Expect and How to Prepare in 2026

Receiving an IRS audit notice is one of the most stressful financial events you can experience. But with proper preparation and the right representation, most audits are resolved without major consequences.

Types of IRS Audits

Correspondence Audit

• Most common: About 75% of all audits
• How it works: The IRS sends a letter requesting documentation for specific items
• Scope: Usually limited to 1-2 issues (charitable donations, business expenses, etc.)
• What to do: Respond by the deadline with the requested documents

Office Audit

• Medium complexity: You visit a local IRS office
• Duration: Usually 1-2 sessions
• Scope: More thorough than correspondence, may cover multiple items
• What to do: Bring organized records and consider having a representative

Field Audit

• Most comprehensive: An IRS revenue agent visits your home or business
• Duration: Can take weeks or months
• Scope: Comprehensive examination of your return and records
• What to do: Always have professional representation

What Triggers an Audit?

The IRS uses a computer scoring system (DIF score) plus manual review. Common triggers:

• High deductions relative to income: Business expenses, charitable donations, home office deductions that seem disproportionate
• Schedule C with losses: Consistent business losses raise "hobby loss" concerns
• Cash-intensive businesses: Restaurants, retail, construction
• Cryptocurrency transactions: The IRS is increasing enforcement in this area
• Missing income: If your reported income does not match what was reported to the IRS on W-2s and 1099s
• Random selection: A small percentage of audits are purely random
