To avoid a future tax audit, ensure maximum accuracy by double-checking all figures, reporting all income (including 1099s), and using e-filing, which reduces calculation errors. Maintain meticulous, organized records to substantiate all deductions, avoid rounding numbers, and avoid claiming excessive business expenses or losses.
That being said, it's important to be aware of “triggers” for IRS audits, below is a list of some of the more egregious items.
Many people worry about IRS audits. But the chances of being audited are actually very low for most individuals. Recent IRS data shows the IRS examined 0.40% of individual returns filed and 0.66% of corporation returns filed. Most of the IRS's focus is on large businesses and high-income earners.
Not reporting all of your income is an easy-to-avoid red flag that can lead to an audit. Taking excessive business tax deductions and mixing business and personal expenses can lead to an audit. The IRS mostly audits tax returns of those earning more than $200,000 and corporations with more than $10 million in assets.
The IRS $600 rule refers to a change in reporting requirements for third-party payment apps (like Venmo, PayPal) for taxable income from goods and services, where platforms must send a Form 1099-K if you receive over $600 in a year, intended to capture gig economy/side hustle income, though delays and phased implementation have adjusted the timeline, with current rules for 2024 using a higher threshold ($5,000) before fully phasing to $600 for future years, but remember all taxable income, regardless of form, must always be reported.

The IRS generally audits a larger share of high-income taxpayers than those with lower incomes, as illustrated in Figure 1. However, those who claim the Earned Income Tax Credit (EITC)—who typically have low incomes—are much more likely to face an audit than all but the highest-income taxpayers.
The IRS can usually assess tax, by law, within 3 years after your return was due, including extensions, or – if you filed late – within 3 years after we received your return, whichever is later. This time period is called the Assessment Statute Expiration Date (ASED).
A tax audit doesn't automatically mean you're in trouble. While it's true that the IRS can audit people suspected of doing something wrong, that's not always the case. As part of the audit process, the IRS audits a random portion of the taxpaying public every year.
What happens during an audit? Internal audit conducts assurance audits through a five-phase process which includes selection, planning, conducting fieldwork, reporting results, and following up on corrective action plans.
The four key components of audit risk, as defined by the Audit Risk Model, are Inherent Risk, Control Risk, Detection Risk, and Acceptable Audit Risk (or Overall Audit Risk), representing the susceptibility of accounts to misstatement, failures in internal controls, the auditor's chance of missing errors, and the acceptable level of risk for the audit, respectively, all combining to determine if a materially misstated financial statement receives an inappropriate opinion.
If the deductions, losses, or credits on your return are disproportionately large compared with your income, the IRS may want to take a second look at your return. Taking a big loss from the sale of rental property or other investments can also spike the IRS's curiosity.
There are five potential threats to auditor independence: self-interest, self-review, advocacy, familiarity, and intimidation. Any lack of independence compromises the integrity of financial markets.
