Wall Road discovered an ETF tax loophole price $8.7 billion

Image this: you’ve held a inventory for 20 years, and now it is price hundreds of thousands. But your price foundation is sort of nothing, however promoting triggers an enormous tax invoice, so that you maintain.

That’s the lure hundreds of thousands of long-term buyers face. The extra profitable the funding, the extra painful the exit.

However a rising variety of rich Individuals have discovered a approach out. They’re not promoting, they’re not donating, however they’re seeding brand-new ETFs with their appreciated inventory and strolling away with diversified fund shares.

Right here’s what you should know earlier than this door doubtlessly closes

Morningstar identifies 39 ETFs seeded with $8.7 billion in appreciated belongings.

The technique known as a Part 351 alternate. A brand new Morningstar evaluation based mostly on analysis by Brent Sullivan and Elliot Rozner reveals how briskly it’s rising. Between 2021 and 2025, 39 U.S. ETFs launched with roughly $8.7 billion in seed belongings from particular person buyers.

That is not a distinct segment approach. Wealth managers are transferring shoppers’ concentrated, low-basis shares into newly shaped ETFs. The investor receives ETF shares in return. No achieve is acknowledged on the time of switch if the alternate satisfies Part 351 necessities.

The attraction is simple: you reposition appreciated holdings right into a diversified technique. You keep away from an instantaneous capital positive aspects occasion. You entry the structural tax advantages of the ETF wrapper, together with in-kind redemptions that reduce future fund-level realizations.

How Part 351 lets buyers swap inventory for ETF shares tax-free

Part 351 of the Inner Income Code dates again to 1921. Congress created it to assist small enterprise house owners incorporate with out triggering a taxable occasion. The rule says you possibly can switch property to an organization in alternate for inventory, tax-free, if the transferors collectively personal no less than 80% of the brand new entity.

Wealth managers realized this outdated rule applies to ETFs. A shopper contributes a portfolio of appreciated securities to a newly created ETF earlier than launch. The shopper receives ETF shares, and the associated fee foundation carries over.

The fundamental mechanics:

• The investor transfers shares from a taxable account right into a brand-new ETF.
• The investor receives ETF shares with their authentic price foundation.
• The ETF supervisor later rebalances right into a goal portfolio utilizing in-kind transactions.
• Capital positive aspects are deferred till the investor ultimately sells the ETF shares.

As soon as contained in the ETF wrapper, the supervisor can rebalance with out triggering positive aspects for shareholders. The ETF’s in-kind creation and redemption mechanism handles that. It’s a double layer of tax effectivity stacked on a single transaction.

The strict diversification take a look at you could cross to qualify

Part 351(e) features a vital guardrail. The tax-free therapy is denied if the switch ends in “diversification” of the investor’s pursuits. Treasury rules implement this by way of what’s often known as the 25/50 take a look at.

The 25/50 diversification guidelines:

• No single inventory can characterize greater than 25% of the belongings you contribute.
• Your prime 5 holdings can’t exceed 50% of complete contributed belongings.
• Money is excluded from the calculation.
• ETF holdings are evaluated on a look-through foundation

In case your portfolio is already diversified, the alternate qualifies. If it’s concentrated in a single or two shares, it doesn’t. You’ll be able to’t dump $10 million of Nvidia into an ETF and name it a 351 alternate, as CNBC reported; the portfolio should meet the take a look at on the time of contribution.

The buyers and companies driving the $8.7 billion wave

This technique shouldn’t be for on a regular basis retail buyers, as minimal contributions sometimes begin at $1 million. Alpha Architect, one of many early movers, recommends a minimal portfolio of that dimension. Cambria Funds’ first 351-seeded ETF, launched in December 2024, carried the identical ground.

Giant wealth administration companies create personal ETFs through 351 conversions for his or her shoppers. Smaller companies now take part by way of publicly traded ETFs. Current launches embody Stance’s Sustainable Beta ETF (November 2024), Cambria’s Tax Conscious ETF (December 2024), and Longview’s Benefit ETF (February 2025).

• Nancy Pelosi sells $1M of struggling dividend inventory
• Verizon’s $20 billion acquisition resets dividend outlook

Morningstar senior analyst Daniel Sotiroff informed CNBC he expects the development to speed up. For buyers with taxable accounts stuffed with embedded positive aspects, 351 exchanges resolve an issue that conventional tax-loss harvesting can’t repair.

The IRS is paying consideration, and so is Congress

The tax-free therapy shouldn’t be assured. Morningstar’s evaluation flags two aggressive patterns that might invite IRS scrutiny.

Purple flags the IRS is watching:

• “Stuffing”: Packing a brand new ETF with extremely appreciated belongings that don’t match the fund’s said technique.
• “Sequential seeding”: Repeatedly creating new ETFs solely to cycle appreciated inventory into tax-deferred wrappers.

Each patterns could lead on the IRS to re-characterize the transaction and impose fast capital positive aspects tax. The company has broad authority beneath the financial substance doctrine to problem transactions that lack enterprise function past tax avoidance.

Congress has observed too. Senator Ron Wyden launched laws geared toward limiting 351 exchanges’ entry to ETFs, Bloomberg reported. The U.S. Treasury Division held early discussions with the Funding Firm Institute about potential steerage. Wyden referred to as the technique a loophole that Congress has tried to shut no less than 3 times earlier than.

How the loophole turns into everlasting by way of the step-up in foundation

Right here’s the half that makes tax specialists uneasy. Should you defer positive aspects by way of a 351 alternate and maintain these ETF shares till demise, your heirs obtain a stepped-up price foundation beneath present regulation. The embedded achieve disappears totally. Nobody ever pays the tax.

Underneath Part 1014 of the Inner Income Code, inherited belongings reset to honest market worth on the date of demise. Mixed with the 351 alternate, this creates a pathway from concentrated inventory to diversified ETF to tax-free inheritance.

Morningstar’s evaluation quotes a 1999 congressional press launch evaluating these methods to “a phoenix rising from the ashes.” Every time Congress closes one path, the trade finds one other. The ETF seed is the most recent model.

What this implies for those who’re sitting on massive unrealized positive aspects

You in all probability don’t have $1 million in a single taxable account. Most readers don’t. However the mechanics of this technique nonetheless matter to you, for 2 causes.

Why on a regular basis buyers ought to concentrate:

• If Congress restricts 351 exchanges, the broader ETF tax benefit (in-kind redemptions) might additionally come beneath scrutiny. That impacts each ETF you personal.
• Should you maintain concentrated positions from inventory compensation, startup fairness, or long-term holdings, smaller-scale variations of this idea might ultimately attain decrease minimums.
• Understanding how the rich defer taxes helps you pressure-test your personal tax technique. Should you’re paying greater than crucial, a dialog with a tax advisor is definitely worth the charge.

The usual ETF tax benefit already works in your favor. U.S. inventory ETFs prevented tax on greater than $211 billion in positive aspects in a latest yr, Bloomberg discovered. That’s not only for the ultra-rich. Each time you maintain an S&P 500 ETF that distributes zero capital positive aspects, you profit from the identical structural characteristic.

The dangers it is best to weigh earlier than assuming this technique is protected

The 351 alternate is authorized right now. Whether or not it stays totally intact will depend on regulatory and legislative motion that’s already underway. Listed here are the sensible dangers, whether or not you’re contemplating the technique straight or evaluating ETFs that had been seeded this manner.

Key dangers to contemplate:

• IRS recharacterization: If the company determines a 351 alternate lacks financial substance, the investor owes capital positive aspects tax retroactively
• Legislative threat: Pending proposals from Senator Wyden and Treasury discussions might slender or remove the technique
• Liquidity lock: As soon as your belongings are within the ETF, you possibly can’t simply pull them out. Promoting ETF shares triggers the deferred achieve.
• Rebalancing lag: Newly seeded ETFs can take as much as 12 months to totally align with their goal allocation, per Kitces.com analysis
• Excessive minimums: Most publicly traded ETFs require $1 million or extra to take part

CFP Charles Sachs of Imperio Wealth Advisors informed CNBC he avoids the technique as a result of it limits shopper flexibility. When you’re inside, switching methods is tough with out triggering the very positive aspects you deferred.
