    "description": "Tax audits loom large in the American imagination. The word \"audit\" conjures images of agents rifling through shoeboxes of receipts, and taxpayer surveys consistently show that audit fear is a primary motivator for compliance. Most people overestimate their personal audit risk by at least an order of magnitude, guessing somewhere between 5% and 10% per year, when the actual rate for the median filer is closer to 0.1%.\n",

This is likely an overestimate of any single taxpayer's cumulative risk because audit selection is not random: the IRS concentrates resources on EITC claimants, high-income filers, and returns with specific red flags. A median-income W-2 filer's true annual audit rate is closer to 0.1%, implying a lifetime probability around 6%. The 15% figure represents the population-average rate if audits were distributed uniformly across all filers, which they are not.\n",

  "caveats": "The population-average audit rate conceals a U-shaped distribution by income. Filers claiming the Earned Income Tax Credit (under ~$25,000 AGI) face audit rates of 0.3-0.4%, driven almost entirely by correspondence audits verifying credit eligibility. Filers in the $50,000-$500,000 range face rates as low as 0.1%. Filers above $10 million face rates of 4% or higher, though even those rates have fallen steeply since 2010. About 78% of all individual audits in FY 2024 were correspondence audits (conducted by mail), not the in-person field examinations most people picture. The lifetime figure here assumes a constant audit rate, which is unrealistic: rates have varied by a factor of four over the past 15 years alone. A filer who spends their entire career as a median-income W-2 employee has a meaningfully lower lifetime audit probability than the headline figure.\n",
