The Supreme Court is set to hear oral arguments Tuesday on a case that could affect broad swaths of the U.S. tax code and federal revenue.
The closely watched case, Moore v. United States, involves a Washington couple, Charles and Kathleen Moore.
Designed as a transition tax, the legislation required a one-time levy on earnings and profits accumulated in foreign entities after 1986.
While the 16th Amendment outlines the legal definition of income, the Moore case questions whether individuals must "realize" or receive profits before incurring taxes.
It's an issue that has been raised during past federal "billionaire tax" debates and could affect future proposals, including wealth taxes.
