Forrest Jr. and his two siblings started 2016 with personal fortunes in the vicinity of $25 billion. Now if Forrest’s fortune had been subject to a significant estate tax after he passed on, the collective wealth of his four daughters in 2017 would be substantially less than that $25 billion.
The just-released 2017 Forbes list of America’s 400 richest shows otherwise. Forbes puts the wealth of each of Forrest’s four daughters at $6.3 billion, for a total of $25.2 billion. That’s almost identical to the 2017 fortunes of their Aunt Jacqueline and their Uncle John, each at $25.5 billion. The Bloomberg Billionaires Index reports similar numbers.
Should any of this surprise us? Not really. We’re seeing Mars family history repeat itself. Eighteen years ago, Forrest Mars Sr., the original Mars family billionaire, died. The Forbes 400 lists from the years surrounding 1999 show that the Mars family lost no wealth to estate tax back then either.
But the Mars family must at least be paying oodles of income tax, right? Nope. How could that be? This particular tax-avoidance story starts over a century ago, when Frank Mars incorporated his candy business.
Back then, the value of the stock in Mars Inc. had only minimal value. But over the years the stock appreciated considerably in value. By 1988, that appreciation had made the Mars family the wealthiest clan in America. The Mars billionaires still rank as one of America’s wealthiest families, in no small part because none of the gains in the value of the family’s Mars stock have ever been subject to income tax.
