Trove of Never-Before-Seen Records Reveal How the Wealthiest Avoid Income Tax

A vast cache of Internal Revenue Service records exposes how the ultrawealthy routinely pay little or no federal income tax relative to the enormous gains in their fortunes. By matching tax returns to yearly wealth estimates from Forbes, the analysis computes a "true tax rate" that compares taxes paid to wealth growth. From 2014-2018 the 25 richest Americans collectively saw their net worth rise about $401 billion while paying $13.6 billion in federal income taxes - a true tax rate of roughly 3.4%. Individual examples are striking: Warren Buffett’s wealth rose $24.3 billion while he paid about $23.7 million in income taxes (a 0.1% true rate); Jeff Bezos had years when he paid nothing, and over 2006-2018 his wealth climbed $127 billion while he paid about $1.4 billion in personal federal taxes (roughly a 1.1% true rate). The records show how unrealized gains on stock and property, generous deductions, investment losses and other legal strategies let billionaires avoid triggering taxable income.

Those revelations reshape debates about tax fairness and federal revenue. Because most wealth gains are untreated until assets are sold, higher statutory income rates often miss the primary avenues of elite tax avoidance; many of the top fortunes would be little affected by incremental rate changes. The data also spotlights enforcement gaps: budget cuts and weaker IRS scrutiny have allowed aggressive tax strategies to persist while audits increasingly fall on lower-income people. The disclosures were cross-checked and individuals were asked to respond; some defended their compliance. The material fuels further investigation into loopholes, enforcement failures and the policy choices that let vast private fortunes grow with minimal income-tax contributions.
