The Ways & Means Committee received a Joint Fiscal Office briefing on two tax proposals: a proposed 4% "investment proceeds" surtax modeled on the federal net investment income tax and a new 13.3% top personal income tax bracket for very high earners. Presenters outlined definitions, who would be affected, revenue estimates, and drafting choices; members asked about impacts on retirees, ESOPs, trusts and nonresident allocation.
