The Internal Revenue Service (IRS) audits tax returns to verify that taxpayers report their income and deductions accurately, minimizing errors and fraud. Audit triggers are specific items or patterns on your tax return that cause the IRS to flag your filing for closer review. Understanding these triggers can help you file with greater accuracy and reduce the stress and risk associated with audits.
Why Does the IRS Use Audit Triggers?
Given limited resources, the IRS prioritizes audits based on returns that most likely contain mistakes or fraudulent claims. Audit triggers work like smoke detectors—they alert IRS systems to potential problems. While not every trigger results in an audit, these indicators raise the probability that your return will be selected.
Common Audit Triggers to Watch For
Here are some of the most frequent audit triggers that can increase scrutiny of your tax return:
- High Income Levels: Taxpayers with higher earnings typically face more scrutiny because errors or fraudulent claims can lead to significant tax revenue losses.
- Large Charitable Deductions: Claiming disproportionately high charitable contributions relative to income can raise questions from the IRS.
- Self-Employment Income: Self-employed individuals often have more complex returns, which increase opportunities for missed income or inflated business expenses.
- Rental Losses and Real Estate Transactions: Rental properties and sales require detailed reporting. Recurring or excessive rental losses can attract IRS attention.
- Math Errors or Missing Forms: Simple mistakes or failure to include necessary documentation can trigger IRS follow-up.
- Cash Transactions and Reported Tips: The IRS closely monitors unreported cash income, especially in cash-heavy businesses.
- Home Office Deductions: Claims for home office expenses are commonly scrutinized, as they are frequently overstated or incorrectly calculated.
- Claiming the Earned Income Tax Credit (EITC): Due to prior abuse, the EITC is one of the most audited tax credits.
Real-World Examples
- A taxpayer reports $50,000 in charitable donations on a $60,000 income, which appears inconsistent.
- A landlord claims rental losses year after year without clear supporting income.
- A business owner reports low income despite significant cash transactions.
These examples highlight common triggers that can increase the chance of an audit.
Who Is More Likely to Face Audit Triggers?
Audit triggers can affect any taxpayer, but certain groups are at higher risk, including:
- High earners
- Small business owners and freelancers
- Individuals claiming numerous tax credits or deductions
- Taxpayers with complex financial situations, such as rental properties or investment income
Tips to Avoid Audit Triggers
- File accurate and complete returns with all necessary documentation.
- Avoid exaggerating deductions or credits.
- Double-check math and report all income sources.
- Use reputable tax software or consult a tax professional to reduce errors.
- Maintain organized records and receipts, particularly for large or unusual claims. For guidance on documentation, see our article on record keeping for taxes.
Addressing Common Misconceptions
- Audits are not only triggered by wrongdoing; sometimes returns are selected randomly or due to data mismatches.
- Even small errors or missing forms can prompt IRS review.
- Filing late generally results in penalties but won’t necessarily trigger an audit unless combined with other risk factors.
How the IRS Contacts You
If your return is selected for audit, the IRS will contact you by mail. They do not initiate audits by phone or email. Always verify correspondence through official IRS channels.
