Four decades later, the firm he and his friends founded, Susquehanna International Group, is a sprawling global company that makes billions of dollars. Yass and his team used their numerical expertise to make rapid-fire computer-driven trades in options and other securities, eventually becoming a giant middleman in the markets for stocks and other securities. If you have bought stock or options on an app like Robinhood or E-Trade, there’s a good chance you traded with Susquehanna without knowing it. Today, Yass, 63, is one of the richest and most powerful financiers in the country.
But one crucial aspect of his ascent to stratospheric wealth has transpired out of public view. Using the same prowess that he’s applied to race tracks and options markets, Yass has taken aim at another target: his tax bill.
There, too, the winnings have been immense: at least $1 billion in tax savings over six recent years, according to ProPublica’s analysis of a trove of IRS data. During that time, Yass paid an average federal income tax rate of just 19%, far below that of comparable Wall Street tradersJeff Yass: The Billionaire GOP Mega-Donor Gaming the Tax System — ProPublica
