Filing your taxes accurately is essential to avoid unnecessary stress, penalties, or scrutiny. While most taxpayers will never face an audit, certain mistakes on a tax return can increase the chances that the Internal Revenue Service (IRS) takes a closer look.
Understanding the most common tax filing errors can help you avoid problems and ensure your return is processed smoothly. In this guide, we’ll cover the mistakes that may trigger an audit and how you can prevent them.
What Is an IRS Audit?
An audit is a review of a taxpayer’s financial information and tax return to verify that the reported income, deductions, and credits are accurate.
Audits can happen for a variety of reasons, including:
- Random selection
- Mathematical errors
- Suspicious deductions or credits
- Income mismatches
Most audits are conducted by mail and involve providing documentation to support items reported on your tax return.
10 Common Tax Filing Mistakes That May Trigger an Audit
1. Underreporting Income
One of the most common reasons taxpayers get audited is failing to report all sources of income.
The IRS receives copies of many income forms such as:
- W-2 forms
- 1099 forms
- Investment statements
If the income reported on your return doesn’t match what the IRS has on record, it may trigger an audit review.
2. Claiming Excessive Deductions
Deductions are valuable, but claiming unusually large deductions compared to your income can raise red flags.
Common deductions that the IRS reviews closely include:
- Business expenses
- Charitable contributions
- Home office deductions
For example, claiming very high charitable donations relative to income could attract attention.
3. Incorrectly Claiming the Home Office Deduction
The home office deduction can be beneficial for self-employed individuals, but it must meet strict eligibility requirements.
The space must be used exclusively and regularly for business purposes. If the same space is used for personal activities, the deduction may not qualify.
4. Math Errors and Incorrect Calculations
Simple math mistakes are surprisingly common.
While many calculation errors are corrected automatically by the IRS, repeated or significant errors may cause your return to be flagged for review.
Using tax software or working with a professional can greatly reduce these mistakes.
5. Claiming Credits You Don’t Qualify For
Tax credits can significantly reduce your tax bill, but incorrectly claiming them may trigger additional scrutiny.
Examples include:
- Earned Income Tax Credit
- Child Tax Credit
- Education tax credits
Because these credits are frequently misclaimed, the IRS carefully reviews them.
6. Rounding Numbers Excessively
Rounding numbers is allowed, but consistently reporting deductions or expenses as perfect round numbers (such as $5,000 or $10,000) may appear suspicious.
Detailed, accurate records are always best.
7. Reporting Large Business Losses Year After Year
Small business owners and self-employed individuals sometimes report losses while still operating their businesses.
If your business shows losses for multiple consecutive years, the IRS may question whether the activity is a legitimate business or a hobby.
8. Large Cash Transactions
Businesses that deal heavily in cash can sometimes attract additional scrutiny. If reported income appears inconsistent with industry norms, the IRS may investigate further.
Maintaining proper accounting records is essential.
9. Filing Late or Amending Returns Frequently
Missing deadlines like Tax Day or frequently submitting amended returns can sometimes draw attention to a tax account.
While late filing alone doesn’t guarantee an audit, it may increase the likelihood of additional review.
10. Mismatched Information
If the information on your tax return does not match IRS records, it can automatically trigger an inquiry.
Common mismatches include:
- Incorrect Social Security numbers
- Employer information errors
- Income discrepancies
Always double-check your forms before submitting your return.
How to Reduce Your Chances of an IRS Audit
While no method guarantees you won’t be audited, these practices can greatly reduce your risk:
- Report all income accurately
- Keep receipts and financial records
- Claim only legitimate deductions
- Review your return carefully before filing
- Work with an experienced tax professional
Professional tax preparation ensures your return is complete, compliant, and properly documented.
