A tax loophole embedded in the way exchange-traded funds are structured is bleeding the US Treasury of $48 billion every year. The gap, long known to financial insiders, lets ETF managers defer or avoid taxes that ordinary investors would owe on dividends and capital gains. Congress and the Treasury Department have discussed closing it, but so far no fix has made it into law.
How the loophole works
Unlike mutual funds, ETFs don't have to sell underlying securities when investors cash out. Instead, they use a creation-redemption mechanism that lets large institutional investors swap baskets of stocks directly with the fund. Those in-kind exchanges aren't taxable events, so the built-up gains inside the fund can roll over for years without triggering a tax bill. The result: investors can sidestep the annual tax bite that normally comes from dividend payouts and realized gains in a regular fund.
That structure was designed for efficiency, but the industry has pushed it to its limits. By using options, futures, and other derivatives within the tax-sheltered shell, ETF providers can wring out even more tax-free returns. The $48 billion figure comes from estimates by the Treasury and outside researchers looking at lost revenue from deferred taxes on ordinary income and capital gains.
Why $48 billion matters
To put that number in perspective: $48 billion is roughly what the US spends on the entire Environmental Protection Agency each year. It's also about a third of the annual budget for the Department of Housing and Urban Development. At a time when the federal deficit is running above $1 trillion, every billion matters. Lawmakers searching for revenue to fund infrastructure, child care, or clean energy have eyed this loophole as low-hanging fruit.
Yet attempts to close it have stalled. The ETF industry argues that the tax treatment is legal and baked into the rules. They say any change would hurt millions of ordinary investors who use ETFs for retirement savings. Critics counter that the loophole primarily benefits wealthy individuals and institutional players who can afford to stay invested for decades without realizing gains.
What's being done
The Treasury Department included a proposal to restrict the in-kind transfer tax break in its 2024 Greenbook, a wish list of tax changes. But the measure didn't make it into the Inflation Reduction Act or any subsequent tax package. Several members of Congress have introduced bills to eliminate the loophole, only to see them die in committee. The industry's lobbying muscle is strong: ETF assets under management have grown to more than $7 trillion, and the largest providers spend heavily on Capitol Hill.
What happens next
The next window for action could come in 2025, when parts of the 2017 Tax Cuts and Jobs Act expire. That debate will force lawmakers to revisit dozens of tax provisions, and the ETF loophole is expected to be part of the conversation. For now, the Treasury keeps losing $48 billion a year, and the industry keeps growing. Whether that loss eventually triggers a legislative fix or stays on the books remains an open question.
