MO HB3444

Creates a new 1.9% annual tax on endowments of higher education institutions that are affiliated with abortion facilities, offer medical residencies/fellowships training in abortion procedures, or support abortion facilities in any manner, effective January 1, 2027

Institutions that become subject to the endowment tax remain permanently subject to it even if they later sever abortion-related affiliations

Authorizes an additional 0.17% reduction in Missouri's top individual income tax rate beginning in 2027, but only if one or more institutions becomes subject to the new endowment tax

Maintains existing graduated income tax structure with rates ranging from 1.5% to 6%, with the current top rate set at 4.95% as of 2023 and existing trigger mechanisms for further rate reductions based on revenue growth

Deposits revenue from the endowment tax into the general revenue fund, with the Department of Revenue authorized to promulgate implementing rules
