IRS Audit Triggers Small Business Owners Should Avoid

Sarah B

If you run a small business, the word “audit” probably sends a chill down your spine. No one wants the IRS taking a closer look at their books. While being audited doesn’t automatically mean you did something wrong, it does mean time, paperwork, and added stress. The good news is that many audits are avoidable. By understanding common IRS audit triggers, you can take steps to stay under the radar and maintain peace of mind.


Failing to Accurately Report Income

The IRS gets copies of the 1099 forms sent to you. If your reported income doesn’t match what they receive, that’s an immediate red flag. Underreporting income is one of the fastest ways to attract attention.


Even if the mistake was unintentional, it could still prompt an audit. To avoid issues, keep detailed records of all payments and compare them against your 1099s before filing. If you receive income that isn’t reported on a 1099, like cash or app-based payments, make sure you include that, too. Consistent and honest reporting helps you stay compliant and avoid unwanted scrutiny.


Mixing Business and Personal Finances

Mixing your personal and business finances can lead to messy records and questionable deductions. It’s tempting to use your business account for a personal expense or vice versa, especially when you’re in a hurry. But doing so increases the chance of errors and can raise red flags during tax season.


Make it a habit to:

  • Use separate bank accounts and credit cards for business and personal transactions
  • Reimburse yourself for business expenses paid personally, with documentation
  • Keep detailed notes about each expense and why it qualifies as business-related

A clean financial separation shows the IRS that you take your responsibilities seriously and that your records are accurate and trustworthy.


Excessive Deductions

Deductions are a great way to reduce your taxable income, but they need to be reasonable and well-documented. If your deductions seem unusually high for your type of business, the IRS may want to take a closer look.


Home office, vehicle use, travel, and meals are common deductions that often get misused. Make sure your deductions are truly related to the business and backed by receipts or logs. If you’re unsure, it’s worth talking to a tax professional to confirm what qualifies.


Claiming a home office deduction? Ensure the space is used exclusively and regularly for your business. Using your personal car? Keep a mileage log that clearly separates business and personal trips. These details can make all the difference if you’re ever asked to prove your claims.


Payroll and Contractor Errors

If you have employees or work with contractors, payroll and tax reporting can be another audit risk. Misclassifying a worker as an independent contractor when they function more like an employee is a common mistake that can cost you.


Make sure you:

  • Use the correct forms (W-2 for employees, 1099-NEC for contractors)
  • Withhold and pay employment taxes properly
  • Understand the legal distinctions between employee and contractor status

Payroll compliance is a complex area. Consider using a payroll service or consulting with an accountant to avoid making costly errors.


Confidence Starts With Compliance

Audits may never be entirely avoidable, but many of the most common triggers can be managed with good habits and attention to detail. When you keep clean records, follow IRS guidelines, and approach your business finances with care, you’re doing more than just avoiding penalties. You’re building a business rooted in integrity.


If you’re ever unsure, don’t guess. Reach out to a trusted accounting professional who can help you understand what the IRS expects and how to stay in compliance. A little support goes a long way in keeping your small business audit-ready and focused on growth.

If a couple gets separated or divorced, it affects tax obligations. The IRS considers couples married for tax purposes until a final decree is issued. After separating or divorcing, update your Form W-4 with your employer and check withholding using the IRS estimator.  Generally, alimony payments and child support payments aren’t deductible by the paying spouse or included in the taxable income of the recipient spouse. (Tax treatment of alimony payments is different if they’re being made under agreements entered into on or before December 31, 2018.) Property transfers due to divorce typically aren’t taxed but may require a gift tax return. Also, be aware that only one parent can claim a child as a dependent.
