What Triggers an IRS Audit? 10 Red Flags and How to Avoid Them

An IRS audit is a review of an individual’s or organization’s financial information to ensure accuracy and compliance with tax laws. Understanding what triggers these audits can help you file your taxes correctly and reduce the chance of being audited. This article explains common IRS audit triggers, provides strategies to minimize audit risk, and outlines steps to take if you’re audited.

 

What Is an IRS Audit?

An IRS audit involves the Internal Revenue Service reviewing your financial information and tax returns to ensure all data is reported accurately and complies with tax laws. The primary goal is to verify that the amount of tax reported is correct. Audits are conducted to maintain the tax system’s integrity and ensure that all taxpayers are meeting their tax obligations.​

There are three main types of IRS audits:​

1. Correspondence Audit

This is the most common type of audit and is conducted entirely by mail. The IRS sends a letter requesting additional documentation to support specific items on your tax return. These audits typically focus on simple issues and can often be resolved quickly by providing the requested information.

2. Office Audit:

In this type of audit, the IRS requests that you visit an IRS office for a face-to-face interview and provide specific documents. Office audits are more in-depth than correspondence audits and usually focus on more complex tax issues.

3. Field Audit

This is the most comprehensive type of audit, where an IRS agent visits your home, business, or accountant’s office to conduct a thorough examination of your records. Field audits are typically reserved for complex cases involving businesses or high-income individuals.

 

Common Triggers of IRS Audits

Certain actions or discrepancies can increase the likelihood of an IRS audit. Understanding these red flags can help you avoid them:​

1. Unreported or Underreported Income:

All income, including freelance or gig work, must be reported. The IRS receives copies of all W-2s and 1099s, so discrepancies between reported income and IRS records are easily detected. Failing to report all income can trigger an audit.

2. Excessive Deductions:

Claiming deductions that are disproportionately large compared to your income can raise suspicion. For example, if you claim unusually high charitable contributions or business expenses relative to your income level, the IRS may scrutinize your return more closely. Ensure all deductions are legitimate and well-documented.

3. Discrepancies Between Reported Income and Lifestyle:

If your reported income doesn’t align with your apparent lifestyle or expenditures, the IRS may investigate to determine if income is being underreported. For instance, owning expensive assets or living a lavish lifestyle that seems inconsistent with your reported income can be a red flag.

4. Home Office and Business Expense Deductions:

Misusing home office deductions or mixing personal and business expenses can be problematic. The IRS has specific criteria for what qualifies as a home office deduction. Only claim this deduction if the space is used exclusively and regularly for business purposes. Similarly, ensure that all business expenses are legitimate and separate from personal expenses.

5. Large Charitable Contributions:

Donations that are unusually large relative to your income may prompt the IRS to request verification. While charitable contributions are commendable, claiming deductions that are disproportionately high compared to your income can raise questions. Always keep detailed records and receipts for all charitable contributions.

6. Cash-Intensive Businesses:

Businesses that primarily operate with cash transactions, such as restaurants or salons, are more susceptible to audits due to the potential for unreported income. The IRS is aware that cash transactions are harder to track, making these businesses a focus for audits.

7. Foreign Accounts and Transactions:

Failing to report foreign bank accounts or income from overseas can lead to serious consequences. U.S. taxpayers are required to report all foreign financial accounts if the total value exceeds certain thresholds. The IRS has strict reporting requirements for foreign assets, and non-compliance can result in significant penalties.

8. Consistent Business Losses:

Reporting losses year after year, especially in sole proprietorships, may lead the IRS to question whether your business is actually a hobby rather than a for-profit enterprise. The IRS expects businesses to be profit-driven; consistent losses can trigger scrutiny to determine if the business is legitimate.

9. Rounded Numbers and Estimates:

Frequent use of round numbers or estimates instead of exact figures can appear suspicious. Tax returns should reflect precise amounts. Consistently rounding numbers can suggest a lack of accurate record-keeping, prompting the IRS to take a closer look.

10. High Income Levels:

Higher income earners face increased audit likelihood. According to IRS data, audit rates increase as income rises. For instance, taxpayers earning more than $1 million annually are audited at higher rates compared to those with lower incomes.

 

What are the Chances of Being Audited by the IRS?

​The likelihood of being audited by the IRS is generally low but varies based on income levels. According to the IRS Data Book for Fiscal Year 2023 (covering October 1, 2022, to September 30, 2023), the overall audit rate for individual income tax returns was approximately 0.4%. However, audit rates increase with higher income:​

  • Income under $25,000: Audit rate around 0.4%.​
  • Income between $25,000 and $500,000: Audit rates range from 0.2% to 0.3%.​
  • Income between $500,000 and $1 million: Audit rate approximately 0.6%.​
  • Income over $10 million: Audit rate about 8.7%.​

These figures indicate that while most taxpayers have a low chance of being audited, the probability increases significantly for higher-income earners. ​

 

Strategies to Minimize Audit Risk

Reducing the likelihood of an IRS audit involves proactive and meticulous tax practices. Here are several strategies to consider:

  • Report All Income Accurately: Ensure that all sources of income, including wages, freelance earnings, dividends, and rental income, are accurately reported. The IRS receives copies of income-related forms such as W-2s and 1099s, and discrepancies can trigger audits.​
  • Maintain Detailed Records: Keep comprehensive records of all financial transactions, including receipts, invoices, bank statements, and documentation for deductions and credits claimed. Organized records not only facilitate accurate tax filing but also serve as essential evidence if an audit occurs.​
  • Be Cautious with Deductions: Only claim deductions and credits you are entitled to and ensure they are proportionate to your income level. For instance, claiming unusually large charitable contributions relative to your income can raise red flags. Always have proper documentation to substantiate your claims.​
  • File on Time and Pay Taxes Owed: Timely filing and payment demonstrate compliance and reduce scrutiny. Late filings or payments can result in penalties and increase the likelihood of an audit.​
  • Consult a Tax Professional: If you have complex financial situations, such as owning a business, having significant investments, or dealing with international transactions, seek advice from a qualified tax professional. They can provide guidance tailored to your circumstances and help ensure compliance with tax laws.​
  • Avoid Amended Returns When Possible: Filing amended returns can attract additional scrutiny, especially if they involve significant changes. Double-check your original return for accuracy before filing to minimize the need for amendments.
  • Use Electronic Filing (E-file): E-filing reduces the chances of errors compared to paper returns. The IRS processes e-filed returns faster, which can also reduce audit risk.​

 

What to Do If You’re Audited

Receiving an audit notice from the IRS can be unsettling, but understanding the process and taking proactive steps can help you navigate it effectively. Here’s how to prepare:​

  1. Don’t Panic: An audit does not necessarily indicate wrongdoing. It is a process to verify information and ensure compliance.​
  2. Read the Notice Carefully: The IRS will specify the items under review and the documentation required. Understanding the scope of the audit is crucial.​
  3. Gather Documentation: Collect all relevant records pertaining to the items being audited. This includes receipts, invoices, bank statements, and any other supporting documents.​
  4. Respond Promptly: Adhere to the deadlines provided in the audit notice. Timely responses demonstrate cooperation and can expedite the process.​
  5. Consider Professional Representation: Engaging a tax professional, such as a Certified Public Accountant (CPA) or tax attorney, can provide expertise and representation during the IRS audit. They can communicate with the IRS on your behalf and help ensure that your rights are protected.​
  6. Understand Your Rights: Familiarize yourself with your rights as a taxpayer, including the right to professional and courteous treatment, the right to privacy and confidentiality, and the right to appeal disagreements.​
