Not Every Tax-Savings Scheme is Worth Chasing.

The Newest "Tax-Free" Scheme on Wall Street, and Why the IRS Just Called It Out

If you've built up big gains in stocks, crypto, or a business, you've probably heard someone pitch a clever way to "swap" those assets without paying capital gains tax. Every few years, a new version of this idea circulates, and every few years, the IRS shuts it down.

The latest chapter involves something called a "Section 351 conversion transaction," and the IRS just put the whole strategy on notice in Notice 2026-62, issued together with Revenue Ruling 2026-20. Here's what happened, what it means, and why it's a good reminder that boring, well-established planning usually beats clever schemes.

A Quick Refresher: What Section 351 Was Designed to Do

Section 351 of the Internal Revenue Code says that if you transfer property to a corporation and receive only stock in return, and you're in control of that corporation right after the exchange, you don't recognize gain on the transfer. In plain English: you can move appreciated assets into a corporation you own without triggering tax, because you haven't really "cashed out." You've just changed the form of ownership.

Congress wrote this rule in the 1920s to make it easy to incorporate an ongoing business. Courts have described it as covering situations where "there has been a mere change in the form of ownership" and the taxpayer "has not really 'cashed in'" on the gain. See Rev. Rul. 2003-51; Portland Oil Co. v. Commissioner.

There's even a sister rule for partnerships: under Section 721(a), contributing property to a partnership in exchange for a partnership interest is also tax-free. But Congress built guardrails. Section 351(e) says the tax-free rule does not apply to transfers to an "investment company," and Treas. Reg. § 1.351-1(c) spells out that this means transfers that diversify the investors' holdings of stocks and securities. Similarly, Section 721(b) blocks the same move through partnerships.

How People Were Gaming It

Here's the pitch as the IRS describes it in Notice 2026-62: an investor holding a portfolio of appreciated securities contributes it to a brand-new exchange-traded fund (ETF) in a transaction meant to qualify under Section 351. Then, as part of the same plan:

1. The ETF issues "creation units" to an authorized participant in exchange for different securities that fit the ETF's actual investment strategy (or cash to buy them), and

2. The ETF redeems those units under Section 852(b)(6), a provision that lets a regulated investment company distribute appreciated property on a shareholder redemption without recognizing gain, handing back the very securities the investor contributed, often "shortly after" the contribution.

The net effect? The investor walks away owning an ETF with a materially different portfolio than the securities they started with (which looks a lot like a taxable sale and reinvestment) but without paying tax on the gains. Notice 2026-62, § 2.02(2). The notice also flags a "partnership variation" where concentrated stockholders route the same play through a partnership holding at least 20% non-securities assets, trying to dodge the investment-company rule. Id. § 2.03.

The IRS's response: Revenue Ruling 2026-20, issued the same day, holds that when an investor contributes appreciated securities to an ETF as part of a plan that includes redeeming those securities out shortly thereafter, the whole thing is properly characterized as a taxable exchange under Section 1001 between the investor and the authorized participant, not a tax-free Section 351 contribution. The investor owes tax on the gain.

What Happens Next: Anti-Abuse Rules, Reporting, and Effective Dates

Notice 2026-62 isn't a final rule; it's a warning shot plus a request for comments. But the notice states plainly that Treasury and the IRS are "considering issuing additional guidance or taking other action," which could include regulations, notices, or revenue rulings, and even the potential identification of these transactions as "transactions of interest" or "listed transactions" (categories that carry mandatory disclosure obligations). Id. § 1.

A few things your advisor should have on the radar:

• Retroactivity is on the table. The notice cites Section 7805(b)(3), which allows regulations to apply retroactively "to prevent abuse," and says any guidance "could apply prospectively only or retroactively to transactions that already have taken place." Notice 2026-62, § 1. Anyone who did one of these deals in the past could get caught.

• The IRS can challenge on audit today. The notice says the IRS may challenge these strategies on examination "as inconsistent with existing law," including anti-abuse rules and judicial doctrines; it doesn't need to wait for new regulations. Id.

• Promoters face their own exposure. Promoting an abusive shelter can trigger penalties under Section 6700 for making false or fraudulent statements about tax benefits: up to 100% (or 50%, for false-statement cases) of the promoter's gross income from the activity.

• Existing guardrails already bite. Built-in-loss transfers into a Section 351 corporation are trimmed by Section 362(e)(2), and the rules require detailed statements on tax returns under Treas. Reg. § 1.351-3 for significant transferors and transferee corporations.

The Real Takeaway: Simple Beats Exotic

Here's the honest truth we tell our clients: every one of these strategies shares the same DNA, complexity stacked on complexity, each step individually defensible, the whole clearly at odds with what Congress intended. That's exactly how the IRS framed it: these transactions "are not the result of conventional, long-established tax planning that is consistent with the intent of Congress." Notice 2026-62, § 1.

And notice what the IRS explicitly did not attack: legitimately seeding a new ETF with assets that match its investment thesis and are "intended and expected to be retained," or ordinary incorporations and reorganizations under Section 351 and Section 368, which Rev. Rul. 2003-51 and Rev. Rul. 2015-10 continue to respect. The boring stuff still works. Tax-loss harvesting, retirement account funding, charitable giving of appreciated assets, installment sales, and straightforward entity planning are all well-established, low-risk, and won't blow up in an IRS notice.

Chasing the latest hair-brained scheme means paying steep fees to promoters, filing complicated returns, shouldering audit risk, and now possibly owing back taxes plus interest when the IRS recharacterizes the deal, years after you thought it was done. The exotic strategy that saves you 15% on paper and carries a 40% chance of being unwound is worse than the simple one that works every time.

Quick Answers (FAQ)

• What is Section 351, and why does it exist?

  It lets you move appreciated assets into a corporation you control without paying tax, because you have only changed the form of ownership, not cashed out. IRC § 351(a).

• What were people doing with it?

  Promoters pitched contributing appreciated securities to a new ETF tax-free, then swapping them right back out for a different portfolio, often using the redemption rule in IRC § 852(b)(6). Notice 2026-62, § 2.02(2).

• Why does the IRS object?

  The IRS says that is really just a taxable sale dressed up as a contribution, so tax is owed under IRC § 1001. Rev. Rul. 2026-20 calls the ETF a "mere conduit" and applies the classic substance-over-form cases.

• What is the partnership variation?

  Some promoters added a partnership step, claiming tax-free treatment under IRC § 721(a) and trying to sidestep the investment company rules. Notice 2026-62, § 2.03. The IRS views the whole combination as abusive.

• Is Notice 2026-62 a final rule?

  No, it is a warning shot and a request for comments, but future guidance could include new regulations or even mandatory disclosure as a listed transaction. Notice 2026-62, § 1.

• Could new rules apply to deals already done?

  Yes. The notice says future guidance could be retroactive, citing IRC § 7805(b)(3), and the IRS can already challenge these deals on audit under existing law. Notice 2026-62, § 1.

• What about the promoters?

  Promoters can face penalties up to 100% of their fees for promoting abusive shelters under IRC § 6700.

• What guardrails already apply?

  Transfers to an "investment company" are blocked by IRC § 351(e) and IRC § 721(b), built-in losses are trimmed by IRC § 362(e)(2), and significant transfers must be reported on the return under Treas. Reg. § 1.351-3.

• Is all Section 351 planning now suspect?

  No. Ordinary incorporations and reorganizations still work fine, as shown in Rev. Rul. 2003-51 and Rev. Rul. 2015-10. The IRS only objects to plans that pair a contribution with a quick redemption of the same assets.

• What if I already did one of these deals?

  Do not ignore it. Gather your documents, tell us what was pitched, and we can help you size up your exposure and whether amended returns or protective disclosure make sense.

• What simple alternatives still work?

  Tax-loss harvesting, retirement funding, charitable gifts of appreciated assets, installment sales, and plain-vanilla incorporation and reorganization planning under IRC §§ 351 and 368.
