What Triggers an IRS Audit—and How to Avoid It

February 11, 20254 min read

Don’t Let an IRS Audit Catch You Off Guard

The thought of an IRS audit is enough to make any business owner uneasy. While audits aren’t as common as they might seem, certain mistakes can put you on the IRS’s radar. Understanding what triggers audits and how to stay compliant can save you from unnecessary stress, penalties, and financial setbacks.

If you’re filing your 2024 taxes soon, now is the perfect time to ensure your return doesn’t raise any red flags. Here’s what you need to watch out for and how to protect your business.


Disproportionate Deductions Compared to Income

Deductions are a great way to lower your taxable income, but claiming too many—especially in comparison to your income—can be a red flag. The IRS uses algorithms to compare your deductions to businesses of similar size and industry. If yours seem unusually high, they may take a closer look.

How to Avoid It:

Ensure all deductions are legitimate and well-documented. Keep receipts, invoices, and proof that each deduction is a valid business expense.
Don’t exaggerate expenses. If you didn’t spend it, don’t claim it. Inflated deductions are an easy way to get audited.
Work with a tax professional. A CPA or tax expert can help you maximize deductions without overstepping IRS guidelines.


Misclassifying Employees as Independent Contractors

The IRS has been cracking down on businesses that misclassify employees as independent contractors. Why? Because employee wages are subject to payroll taxes, while payments to independent contractors are not. If you incorrectly classify workers, the IRS may hit you with back taxes and penalties.

How to Avoid It:

Understand the difference. Employees typically work under company control, with set schedules and responsibilities. Independent contractors, on the other hand, work on their own terms and provide services to multiple clients.
Use IRS guidelines. The IRS provides a “common law” test to help businesses determine proper classification.
Keep proper contracts and records. If you hire independent contractors, have agreements in place that clearly define their role and responsibilities.


Failing to Report All Income

If the IRS receives a 1099 or W-2 for income you didn’t report, it’s a guaranteed audit trigger. This is especially important for business owners, freelancers, and those who receive cash payments. The IRS cross-checks reported income with the documents they receive from banks, clients, and employers.

How to Avoid It:

Report all sources of income. This includes cash, digital payments, and any income reported on 1099 forms.
Check for missing 1099s. If a client sent a 1099 and you didn’t receive it, contact them before filing.
Keep detailed financial records. Use accounting software or work with a tax professional to ensure everything is accounted for.


Home Office Deduction Errors

The home office deduction is a great way for small business owners and freelancers to lower their tax bill—but it’s also a common area for mistakes. If not calculated correctly, this deduction can trigger an audit.

How to Avoid It:

Ensure your home office meets IRS requirements. The space must be used exclusively for business and be your primary place of work.
Choose the correct deduction method. You can use the simplified method (a flat rate of $5 per square foot, up to 300 square feet) or the actual expense method (calculating a percentage of home-related expenses).
Keep documentation. If using the actual expense method, maintain records of mortgage/rent, utilities, and maintenance costs.


Why Accurate Record-Keeping is Essential

One of the biggest reasons businesses get audited is simply because they can’t back up their claims. Whether it’s deductions, income, or payroll taxes, the IRS wants proof that your numbers are accurate.

How to Avoid It:

Use accounting software. QuickBooks, FreshBooks, or similar programs can help track income, expenses, and deductions.
Save receipts and invoices. Keep digital or physical copies of every business expense.
Work with a tax professional. Having an expert on your side can help prevent costly mistakes and ensure compliance.


Stay Off the IRS’s Radar and File with Confidence

No one wants to deal with an audit, but by staying organized and following best practices, you can significantly reduce your risk. The key is to be accurate, honest, and well-documented in everything you report.
