(NY Post) - Billionaire software tycoon Robert Brockman cheated the IRS out of billions — and now his heirs are paying the price.

The estate of the late Texas executive has agreed to shell out $750 million to settle what federal prosecutors described as the largest individual tax-fraud case in US history, according to a filing approved this week by the US Tax Court.

News of the settlement was reported by The Wall Street Journal.

The massive payout ends a yearslong legal saga stemming from allegations that Brockman hid more than $2 billion in income from the IRS through a sprawling offshore web of shell companies and secret bank accounts.

Under the terms of the settlement, Brockman’s estate will pay $456 million in back taxes and $294 million in penalties covering tax years from 2004 through 2018, the filing shows.

The IRS initially sought much more — roughly $1.4 billion, including interest. Excluding interest, the agency was pushing for $993 million in back taxes and penalties.

It remains unclear how much interest, if any, Brockman’s heirs will ultimately be required to pay, according to The Journal.

Brockman, a Houston-based automotive software mogul, was indicted by federal prosecutors in October 2020 on a 39-count indictment that accused him of orchestrating a decades-long tax-evasion scheme.

Brockman, a Houston-based automotive software mogul, was indicted by federal prosecutors in October 2020 on a 39-count indictment that accused him of orchestrating a decades-long tax-evasion scheme.

Prosecutors alleged Brockman used a labyrinth of offshore entities in Bermuda and Nevis, along with secret bank accounts in Bermuda and Switzerland, to conceal income generated largely from private-equity investments.

Much of the hidden money stemmed from Brockman’s early backing of Vista Equity Partners, the private-equity powerhouse focused on enterprise software.

According to court filings, he employed encrypted servers, coded language and fishing-themed nicknames to communicate with associates managing his offshore empire — tactics prosecutors said were designed to evade detection by US authorities.

Brockman vehemently denied the allegations.

The criminal case took repeated twists as Brockman’s lawyers argued he was mentally unfit to stand trial due to dementia. Prosecutors countered that he was exaggerating his symptoms to avoid accountability.

A federal judge ruled in May 2022 that Brockman was competent to stand trial.

But the case never reached a jury. Brockman died in August 2022 at age 81 while still awaiting trial.

The government then pivoted to a civil case in US Tax Court, pursuing Brockman’s estate for unpaid taxes and penalties.

The civil matter continued quietly until this week’s settlement filing brought it to a close.

The Brockman case was deeply intertwined with another high-profile tax scandal, which involved Vista Equity Partners CEO Robert F. Smith.

Smith, who became a billionaire through Vista’s meteoric rise, admitted in 2020 that he failed to pay taxes on income linked to Brockman’s offshore structure.

Smith made a non-prosecution deal with the Justice Department in which he agreed to pay $139 million in back taxes and penalties and to cooperate with prosecutors investigating Brockman.

They alleged Brockman had been a critical early financial backer of Vista, funneling more than $1 billion into the firm through offshore vehicles.

Brockman’s longtime Houston tax lawyer, who allegedly advised both Brockman and Smith, died by suicide on the eve of his own criminal trial.

Despite his vast wealth, Brockman cultivated a reputation for extreme frugality.

Former associates told investigators that he stayed in budget hotels and ate frozen dinners in his room while visiting company offices.

He was also known for harboring deep distrust of the federal government — particularly the IRS — which he reportedly described to associates as corrupt and unfairly hostile to taxpayers.

The Post has sought comment from Brockman’s estate.
