The IRS uses a computer program called the Discriminant Function System (DIF) to analyze tax returns and red flag them if they deviate from statistical averages. When a return draws a high DIF score, an agent evaluates it and decides if an audit is necessary. Your business should always be prepared for an audit, and that includes avoid these audit triggers when filing your small business taxes.

Higher Than Average Income

If you report a high amount of income, this may draw red flags for the IRS. Approximately 50% of the returns audited belong to taxpayers earning more than one million dollars per year. For taxpayers who earn more than $5 million, their odds of being audited more than doubles those of taxpayers who earn less.

Underreporting Cash Transactions

Don’t make the mistake of thinking that the IRS has no way to trace cash transactions. Credit card processors submit 1099-K forms to the IRS, which include a report of the total credit card transactions your business processed for the year. The IRS then applies these figures to an undisclosed formula in order to calculate the amount a business should have generated in cash sales. Therefore, if your reported cash sales reflect a lower figure than their formula detects, your business could be at risk for an audit. It’s a smart idea to keep detailed records of both cash and credit card transactions so you can support your claims should your business be audited.

Taking Too Many Deductions

Deductions are important to a small business owner, but claiming too many can raise red flags. Higher than average meal expenses and claiming your car as 100% business can set off alarm bells for the IRS and trigger and audit.

The IRS states that a legitimate business expense must be both ordinary and necessary to qualify as a deduction.

  • Ordinary expenses = common and accepted in your trade or business
  • Necessary expenses = helpful and appropriate for your trade or business. Note that an expense does not need to be indispensable to qualify as necessary.

Claiming Consistent Business Losses

Given the primary purpose of a business is to generate money, reporting losses year after year can lead the IRS to question the legitimacy of your business. If your business gets audited and you claimed losses, be prepared with documentation to demonstrate your business’ earnings and expenses throughout the year.

Be Prepared for an Audit

Your business may never need to go through an audit process, but you should manage your business always knowing that it’s possible. Keep precise records, make sure the numbers on your tax return are accurate and honest, report all income, and take suitable deductions. Lastly, consult with an accountant to be sure the totality of your revenue, expenses, and documents are free of missteps or miscalculations.
