President Donald Trump is weighing a set of tax proposals ahead of November’s midterm elections, and one of them could reshape how crypto profits are taxed. National Economic Council Director Kevin Hassett said on August 11, in an interview with Fox Business host Larry Kudlow, that Trump wants to offer voters new incentives, among them, indexing capital gains to inflation, meaning taxes would apply only to gains adjusted for the rising cost of living rather than to the full nominal gain. Kudlow, a former Trump economic adviser, said he had recently discussed the idea with the president, who “liked the idea of the indexing” and a larger exemption for home sales.
For crypto investors, the proposal is more relevant than it might first appear. Because the U.S. Internal Revenue Service (IRS) treats digital assets as property for federal tax purposes, gains from selling or otherwise disposing of crypto are generally subject to the federal capital-gains framework. A change to that framework could therefore affect Bitcoin, Ethereum, and other digital assets, depending on the final rules. Crucially, though, this remains a discussion point, not law.
What Trump Is Considering
The proposals were floated as campaign material rather than imminent policy. Hassett framed them as promises of what Republicans would deliver “if the Republicans have power in the future,” signaling more announcements before the midterms. Kudlow said Trump was “very interested” in both indexing capital gains and raising the exemption on home sales, reportedly exempting sales of homes worth $2 million or less from capital gains taxes, well above the current exclusion of $250,000 for single filers and $500,000 for married couples.
Indexing capital gains is a long-standing conservative tax idea. Earlier in 2026, Republican Senators Ted Cruz and Tim Scott pushed for it, and in March a group of lawmakers urged Treasury Secretary Scott Bessent to enact it through executive action. It has never become law.
How Indexing Works
Under the current system, a capital gain is simply the sale price minus the cost basis, what you originally paid, plus fees, and inflation is ignored. That means part of what gets taxed is not a real increase in wealth but “phantom” gain caused purely by the dollar losing value over time.
Indexing would change that by raising the cost basis to account for cumulative inflation during the holding period, so tax applies only to the real economic gain. A simplified crypto illustration shows the effect: suppose an investor bought 1 BTC for $30,000 in 2021 and sold it in 2026 for $90,000, a nominal gain of $60,000, taxed at long-term capital gains rates of 0%, 15%, or 20% depending on income bracket. If cumulative inflation over those years was roughly 25%, indexing would lift the cost basis to about $37,500, leaving a taxable “real” gain of $52,500 rather than the $60,000 nominal figure. (Actual rules would define the exact index and method; real-world indexing compounds inflation year by year.)
Why It Matters for Crypto
The reason that illustration matters is the IRS’s property classification: the same logic applies to every digital asset, automatically. As the example shows, the investor would still owe tax, just on the real gain, not the inflation-driven portion.
The investors who would benefit most are long-term holders, a profile that fits many Bitcoin and Ethereum owners who treat crypto as a multi-year or multi-cycle store of value. Indexing could also ease what economists call the “lock-in effect” — the tendency for investors to hold assets longer than they otherwise would simply to defer a large tax bill. In an analysis of the indexing proposal, the nonpartisan Bipartisan Policy Center noted the change would reduce that effect, and the Congressional Research Service has similarly found that lower effective rates can prompt more asset sales, though it cautions the size of the response is uncertain, with studies estimating a wide range. For crypto specifically, a lower effective tax could, in theory, encourage some long-term holders to sell sooner, adding liquidity and on-chain activity. Because the benefit derives entirely from crypto’s property classification, no dedicated crypto legislation would be needed for it to take effect.
The Limits and the Fine Print
The benefit, while real, is easy to overstate, and several caveats deserve equal weight. First, for assets that have appreciated sharply, as much of large-cap crypto has, the inflation adjustment is a relatively small slice of the total gain. In the example above, the taxable gain falls only about 12.5%, from $60,000 to $52,500; indexing matters far more for lower-appreciation assets held over long periods than for outsized winners.
Second, crypto’s high transaction frequency, multiple purchase lots, and use in DeFi and staking would make calculating an inflation-adjusted basis for each disposal considerably more complex than for a single stock or home.
Third, indexing helps only those realizing gains, it does nothing for the many holders sitting on losses or choosing not to sell, and short-term traders (holding under a year) would see little benefit. It reduces the taxable amount, not the tax rate.
Most importantly, none of this is in effect. As tax specialists note, until any rule is finalized, current capital gains treatment continues to apply.
The Criticism and the Path to Law
The proposal faces real obstacles beyond crypto’s specifics. As per U.S. processes, most tax changes require congressional legislation, making it unlikely any of these ideas become law before the November midterms. Prior administrations, including Trump’s first term, explored indexing capital gains unilaterally through the Treasury Department without Congress, but legal experts cited in Bloomberg’s reporting on the same matter say such a move would likely face court challenges, a question that has been contested for decades. The idea also lacks universal support within the Republican Party, per the same report.
The fiscal critique comes from budget analysts. The version of indexing pushed earlier this year by Republican Senators Ted Cruz and Tim Scott was estimated to reduce federal revenue by about $200 billion. More starkly, the Committee for a Responsible Federal Budget, citing Yale Budget Lab data, warned in March that enacting indexing by executive action could add between $170 billion and $950 billion to the national debt by 2035. That comes as the Congressional Budget Office estimated the federal deficit at about $1.8 trillion for the first 10 months of 2026.
Critics also argue the benefits would skew sharply toward the wealthy. A Congressional Research Service analysis of capital gains indexing found that roughly 90% of the benefit would flow to the top 1% of earners, and about 60% to the top 0.1%.
A Separate Track From Crypto-Specific Tax Ideas
It is worth distinguishing this from the narrower crypto tax proposals circulating in Washington, such as a “de minimis” exemption that would spare small crypto transactions from capital gains reporting. Those are targeted at crypto specifically. The indexing proposal is a broad, economy-wide reform that happens to reach crypto through the property classification, arguably one of the more crypto-favorable tax changes possible without creating a dedicated crypto regime, precisely because it requires no special treatment.
If indexing ever became law, it would be a genuine, if bounded, positive for crypto holders: it would tax only real gains rather than inflation-inflated ones, automatically and without a crypto carve-out. But the emphasis belongs on “if.”
As of now, this is an early campaign-season idea, not a bill or an executive order, and it faces legal, fiscal, and political hurdles, while its practical benefit is proportionally modest for the high-appreciation assets that dominate crypto portfolios. Investors will want to watch whether it hardens into a formal proposal in the months ahead.
