Top IRS Audit Triggers
1. Income doesn’t match IRS records
• W-2s, 1099s, K-1s not reported or reported incorrectly
• IRS computers match your return to what employers and banks send
2. High income levels
• The higher the income, the higher the audit probability
• Especially $200,000 and significantly more at $1 million
3. Large or unusual deductions
• Deductions that are much higher than others in your income bracket
• Charitable contributions disproportionate to income
• Excessive medical, business, or casualty loss deductions
4. Schedule C (self-employed) losses
• Repeated business losses year after year
• High expenses with low income
• Home office deductions that seem aggressive
5. Cash-heavy businesses
• Hair, beauty, trucking, restaurants, bartending, rideshare, vending, etc.
• Industries known for underreporting cash income
