How to Prepare for a Tax Audit & Avoid Red Flags

Introduction

A tax audit is an IRS review of a taxpayer’s financial records and tax return to verify accuracy and compliance with tax laws. While most businesses and individuals are not audited, certain red flags can trigger an IRS audit.

Proper preparation helps minimize audit risks, avoid penalties, and ensure compliance. This guide explains how to prepare for a tax audit, common audit triggers, and best practices for IRS compliance.

What Triggers an IRS Tax Audit?

1. High Deductions Compared to Income

• The IRS flags excessive business expenses that do not align with reported income.
• Large deductions for meals, travel, or home office may attract scrutiny.

2. Underreporting Income (IRC § 61)

• Failing to report 1099 income, cash transactions, or rental income can trigger an audit.
• The IRS cross-checks income reports from employers, banks, and payment processors.

3. Claiming 100% Business Use of a Vehicle

• The IRS rarely accepts 100% business vehicle use unless backed by detailed mileage logs.

4. Excessive Charitable Contributions (IRC § 170)

• Donations should match income level and require proper documentation.

5. Large Cash Transactions (IRC § 6050I)

• Cash deposits over $10,000 are reported to the IRS and may trigger an audit.

6. Frequent Home Office Deductions (IRC § 280A)

• ust meet the exclusive and regular use test.
• Requires proper documentation of square footage and expenses.
