Over 99% of individual taxpayers never get audited in a given year, as the IRS audited only 0.2% to 0.4% of returns recently. This means less than 1 in 500 tax returns face an exam, with audit rates remaining historically low, often below 1% for most taxpayers, with most audits conducted via mail.
While the overall individual audit rates are extremely low, the odds increase significantly as your income goes up (especially if you have business income). According to IRS audit statistics, about 0.4% of total individual returns get audited by the IRS.
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.

If the IRS or California Franchise Tax Board (FTB) believes your income tax returns were fraudulent, jail time becomes a very real possibility.
No, the IRS doesn't catch every instance of unreported income, but their advanced data-matching systems catch most discrepancies involving third-party reporting (like W-2s, 1099s for freelance/interest/dividends) through automated checks, leading to CP2000 notices and potential penalties if missed; however, cash income, crypto, or lifestyle mismatches can also trigger scrutiny, though it's less certain than reported income, and high-income non-filers are a current focus.
The IRS performs audits by mail or in person.

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.
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.
