No one wants to receive a letter from the IRS. While audits are relatively rare, certain mistakes significantly increase the chances of your tax return being flagged. Understanding these errors can help you avoid unnecessary stress and financial consequences.
Below are some of the most common tax filing mistakes that trigger IRS audits and how to prevent them.
1. Reporting Income Incorrectly
One of the most common audit triggers is income mismatch. The IRS receives copies of your W-2s, 1099s, and other income forms. If the numbers on your return do not match what was reported, the IRS will notice.
How to avoid it:
- Report all income, including side jobs and freelance work
- Double-check amounts before filing
- Ensure all tax documents are included
2. Claiming Deductions That Are Too High
While deductions are legal and encouraged, claiming unusually high deductions compared to your income can raise red flags. This is especially true for charitable donations, business expenses, and home office deductions.
How to avoid it:
- Keep proper documentation
- Claim only legitimate expenses
- Understand deduction limits
3. Home Office Deduction Errors
The home office deduction is a common audit trigger because it is often misused. The IRS requires that the space be used exclusively and regularly for business.
How to avoid it:
- Ensure your home office qualifies
- Measure square footage accurately
- Maintain records and photos if possible
4. Math and Data Entry Errors
Simple math mistakes or incorrect Social Security numbers can cause delays, corrections, or audits.
How to avoid it:
- Review your return carefully
- Use professional preparation or review services
- Do not rush the filing process
5. Filing Late or Not Filing at All
Late filings and missing returns often attract IRS attention. Penalties and interest add up quickly.
How to avoid it:
- File on time or request an extension
- Address back taxes promptly
- Seek professional help if you are behind
