Millionaires Surtax Act

The Millionaires Surtax Act introduces a new 10% tax on the portion of an individual's income that exceeds $2 million. This surcharge applies to high-income taxpayers starting with taxable years beginning after December 31, 2026, but the threshold is lowered to $1 million for those filing separately. The law includes specific adjustments for nonresident aliens, citizens living abroad, and charitable trusts, while explicitly excluding this new tax from calculations for other federal credits.
