What it does
This bill fundamentally restructures how capital gains are taxed at death and for high earners. It treats inherited property as if it were sold at death (triggering capital gains tax on appreciation), eliminates the "step-up in basis" that currently allows heirs to inherit assets tax-free, caps preferential capital gains rates for incomes over $1 million, limits like-kind exchange tax breaks to $500,000 annually, and restricts the qualified business income deduction. It offers a $1 million exclusion on inherited gains and a 50% exclusion for family farms/businesses, plus a 5-year installment payment option. The net effect: wealthy individuals and estates pay significantly more tax on wealth transfer; ordinary wage earners and small family farms get some relief.
Why we flagged it
The bill's core mechanism is a comprehensive restructuring of capital gains taxation at death and for high earners, eliminating long-standing tax deferrals (step-up basis, like-kind exchanges) and imposing deemed realization on inherited assets. This is substantive tax policy reform, not a narrow carve-out or messaging bill.
What the text implies
- The deemed realization rule (Section 1261) may create significant liquidity challenges for heirs of illiquid assets (family farms, private businesses, real estate) who must pay capital gains tax within the estate's tax year, even though they cannot immediately sell the asset. The 5-year installment option (Section 6) partially mitigates this but adds complexity.
- The $1 million exclusion on inherited gains is indexed for inflation but rounded DOWN to the nearest $10,000, meaning the threshold may lag actual inflation over time and erode the relief for middle-class estates.
