Red Flags that May Trigger IRS Audits

Many taxpayers have committed errors when filing their tax forms, but have not triggered an IRS audit. Nonetheless, taxpayers should understand red flags that will trigger IRS audits.

In the best-case scenario, taxpayers will furnish the IRS with the appropriate paperwork to satisfy any doubts. Alternatively, the IRS may propose one or more changes, which typically involve penalties, interest, or additional taxes owed. Some taxpayers accept the proposal and pay the extra amount assessed, and the IRS will consider the matter resolved. Sometimes the IRS proposes a change that taxpayers do not accept as valid. In such cases, they have avenues of appeal and, potentially, the option of mediation with the taxing authority.

Most taxpayers aim to avoid triggering any audits from the outset. Avoiding audits starts with accurately reporting all income received throughout the tax year. Even freelancers or part-time workers cannot estimate their income, since the IRS receives copies of their 1099 or W-2 forms. The tax authorities have access to records of all earned and distributed income and automatically conduct a letter audit in the event of a discrepancy.

Simply earning more money can trigger an audit. In 2024, the IRS conducted audits of about 1 percent of those earning less than $200,000 and 4 percent of those earning more than that threshold. Reaching an income threshold of $1 million has triggered around 12.5 percent of audits, reflecting the IRS’s focus on maximizing returns from enforcement and collection activities.

Next, taxpayers who make large donations to charity, while maintaining a relatively small income, also come under scrutiny. Such situations are not uncommon. For example, a taxpayer may make a one-time donation of several thousand dollars to an organization and then lose their job a few months later. Their annual income falls unexpectedly and suspiciously to the IRS, given charitable deductions. Fortunately, one has a clear-cut reason for the discrepancy that the IRS will likely accept.

When such audits occur, it’s important to have valid documentation of the charitable donation, such as filing Form 8283 for donations exceeding $500 and retaining all receipts. Many contributions are non-cash, including art, collectibles, real estate, vehicles, and other assets. In such cases, invest in a professional appraisal of the donated item(s) if the value exceeds $5,000.

For the self-employed and small business owners, another red flag is disproportionate deductions from one’s income. These often involve taking many deductions for uses spanning travel, vehicle maintenance, Internet, and a home office. For the IRS to accept business expenses as legitimate, they must be ordinary and necessary (for the specific trade or business).

Nearly all self-employed people have a certain number of valid business expenses that are deductible from taxes. For these, it’s important to maintain proper records, such as receipts for devices used for business purposes. While you typically do not need to include expenses on the tax form, make sure estimates are accurate and not rounded up too much. For example, it’s acceptable to round up to the nearest dollar. However, having a round number, such as $3,500, can signal to the IRS that your records are inaccurate or poorly maintained.
