The priorities in this shutdown drama couldn’t be clearer. House Republicans once again threaten the financial security of the millions of Americans to exact cuts to programs like Head Start, the Social Security Administration, and the EPA – all while seeking unaffordable tax cuts for multinational corporations, the wealthy, and foreign investors.

Later this year, the Supreme Court will hear Moore v. United States which could become the most important tax case in a century.

The Moore v. United States case that will soon be heard by the U.S. Supreme Court could jeopardize at least $270 billion if SCOTUS finds the entire transition tax to be unconstitutional. The decision could also invalidate other important parts of the current tax system while preempting progressive wealth tax proposals. Such an outcome would represent one of the costliest—and most ethically questionable - Supreme Court decisions in U.S. history.

The Supreme Court is set to hear what could become one of the most important tax cases in a century. If decided broadly—with a ruling that strikes down the Mandatory Repatriation Tax for corporations, effectively making it unconstitutional to tax unrealized income—the Roberts Court’s decision in Moore v. US could stretch far beyond the plaintiffs themselves and would put in legal jeopardy many laws that prevent corporations and individuals from avoiding taxes and level the economic playing field.

Sen. Sinema's bill to stop a seemingly arcane business tax increase that was enacted as part of the 2017 Trump tax law would be hugely beneficial to the private equity industry.
