President Trump is looking for policy wins he can point to before the midterm elections, and one option reportedly on the table is indexing capital gains taxes to inflation, according to Bloomberg. The idea would raise an asset's cost basis to account for cumulative inflation over the holding period, meaning tax would apply only to the real, inflation-adjusted gain rather than the full nominal one. A separate proposal under discussion would create a new tax exemption for certain home sales.
For a concrete example: an investor who bought a stock for $100,000 and later sold it for a nominal gain would, under indexing, only owe tax on the portion of that gain that outpaced inflation over the holding period — potentially shrinking the taxable amount meaningfully for assets held over long, high-inflation stretches.
A Path That Doesn't Need Congress
What makes this proposal different from a typical tax-cut pitch is the mechanism. Indexing capital gains has a documented history of being pursued through Treasury Department regulation rather than new legislation — Trump's first administration explored the same unilateral route. Legal experts cited in Bloomberg's reporting say that path would likely face court challenges, since the legal durability of indexing gains without Congress has never been fully tested.

Landing Against a Growing Deficit
The timing is politically awkward on fiscal grounds. The Congressional Budget Office has pegged the federal deficit at roughly $1.8 trillion over just the first ten months of 2026, and lawmakers have given the prospect of further tax cuts a mixed reception given that backdrop. For markets, indexing capital gains would be a direct tailwind for long-term holders of appreciated assets — including crypto investors who have held positions through multiple inflationary years — though the legal uncertainty around a Treasury-only implementation means any benefit would likely arrive clouded by litigation risk rather than settled law. It's the kind of tailwind that would land alongside an already-frothy market for long-duration risk assets, the same backdrop that has kept insiders like Palantir's CTO cashing out stock even as shares keep climbing.
