Justin Muzinich has served as an economic adviser to an array of Republican Party luminaries, but his time in the Treasury Department has involved some of his most high-profile work.

Muzinich, a former aide to presidential candidates Mitt Romney and Jeb Bush, helped shepherd one of the Trump administration’s biggest legislative victories through Congress and into the rulemaking process: the 2017 rewrite of the tax code.

Serving as counselor to Secretary Steven Mnuchin, Muzinich helped juggle pressure from corporate America, Congress, and outside groups who clamored to get their policy positions into the tax law.

Rep. Kevin Brady was chairman of the Ways and Means Committee when Treasury worked with Congress to craft the overhaul.

“In every meeting, he played a key role in policy and helped guide us toward a successful conclusion, and his personal skills in working with all those in the rooms were hugely helpful,” Brady said.

Muzinich’s influence has grown since the president tapped him to become deputy secretary. The Manhattanite father of two is in part guiding the implementation of the tax bill, helping Treasury craft the rules and regulations taxpayers need in order to comply.

That, along with his other duties as Mnuchin’s No. 2, puts Muzinich in a position to impact financial issues ranging from tax deductions to cryptocurrency.

The Harvard and Yale graduate, like many in the Trump administration’s Treasury Department, is a recent Wall Street transplant. Muzinich previously served as president of Muzinich & Co., an international investment firm created by his father, and he also worked at Morgan Stanley and the hedge-fund EMS Capital.

But Muzinich always had an eye for policy, crafting op-eds over the years for publications like The New York Times, The Washington Post, and Foreign Policy, arguing for reforming the Federal Reserve and for a closer trade relationship with Europe.

Muzinich served as an informal tax-policy adviser to then-candidate Romney and later in an official capacity to Jeb Bush’s campaign. For Bush, Muzinich crafted a tax platform that in part served as a framework for the Trump administration’s code overhaul, featuring many of the same key policy proposals like collapsing the tax brackets, doubling the standard deduction, and reducing the corporate rate.
