It's generally unlikely to get audited by the IRS, with overall individual audit rates around 0.4% (about 1 in 250), but your odds increase significantly with higher income, business activity (like Schedule C), large deductions, and claiming the Earned Income Tax Credit (EITC). While basic returns with modest income and few complexities face very low risk, high-income earners (over $1 million) and self-employed individuals are much more likely to be scrutinized due to complex data and potential for errors.
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.
The IRS mostly audits tax returns of those earning more than $200,000 and corporations with more than $10 million in assets.
The IRS "10k rule" primarily refers to the requirement for businesses and financial institutions to report cash transactions over $10,000 by filing Form 8300 (for businesses) or a Currency Transaction Report (CTR) (for banks), under the Bank Secrecy Act. This rule helps combat money laundering, tax evasion, and terrorist financing, requiring reporting for single transactions or related transactions totaling over $10,000 in cash within a year, with penalties for non-compliance.
To avoid the 22% tax bracket (or any higher bracket), focus on reducing your taxable income through strategies like maxing out 401(k)s and HSAs, deferring bonuses, tax-loss harvesting, smart charitable giving, and strategic asset location, understanding that higher rates only apply to income within that bracket, not your entire income.
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.
When the IRS accepts your return and issues a refund, it doesn't mean your filing is approved or immune from scrutiny. Acceptance is just the first step in processing. The IRS can still audit you for up to three years after filing, or even longer in certain situations.

The 5 Cs of audit (Criteria, Condition, Cause, Consequence, Corrective Action) are a framework for structuring clear, actionable audit findings, explaining what should be (Criteria), what is found (Condition), why it happened (Cause), what the impact is (Consequence/Effect), and how to fix it (Corrective Action/Recommendation) to drive organizational improvement and compliance.
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.
The IRS escalates its collection efforts when the amount owed exceeds $25,000, which can result in severe penalties such as asset seizure, bank levy, wage garnishment, and even passport revocation. If you're unsure how much you owe, you can find more information and guidance here.
