Proposed Provision: F11. Apply a separate 12.4-percent tax on net investment income (NII), as defined in the Affordable Care Act (ACA), payable to the OASI and DI Trust Funds with an unindexed threshold of $400,000, effective 2028 and later. The NII tax would apply to the lesser of NII and the excess of modified adjusted income (MAGI) above the unindexed threshold of $400,000. This single threshold would apply regardless of tax filing status. Do not provide benefit credit on this new revenue.
