Most IRS audits are triggered by automated, data-driven comparisons that detect inconsistencies, specifically unreported income (mismatched 1099s/W-2s), math errors, and abnormally high deductions relative to income. High-income earners, self-employed individuals with large losses, and those with complex foreign accounts are also frequently flagged.

The IRS does not check every tax return. It does not check the majority of them, but the IRS implements methods that track certain factors that would result in a further examination or audit by them.
So What Happens if the IRS Audits Your Tax Return and You Are Missing Receipts? The IRS auditor is looking for evidence that your claimed business expenses are legitimate deductions. The auditor may ask your CPA to recreate a detailed history of your expenses using bank records and cancelled check.
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.
What is a 1099-K form? IRS Form 1099-K is a tax document that reports any payments you received through third-party networks like Venmo, PayPal, or Apple Pay. If you receive more than $20,000 in at least 200 transactions through these platforms, you'll likely get a 1099-K.
