The United States is home to around 900 billionaires, and their combined personal wealth hit a record $7.6 trillion as of Labor Day 2025, according to data cited by the nonprofit Americans for Tax Fairness. That figure has more than doubled in less than eight years.
While billionaires continue to gain more wealth, many also continue to benefit from some tax laws that let them keep a greater percentage of their money. This is true in states with comparatively low tax rates as well as states with high rates, like New York.
