Updated October 22, 2026: The accompanying video describes Treasury’s July warning about specialized ETF tax strategies. Its statement that no formal guidance had yet been issued is now historical. Treasury and the IRS released Revenue Ruling 2026-20 and Notice 2026-62 in September, subsequently published in the Internal Revenue Bulletin.
The article therefore separates three things: the video’s July context, the transaction covered by the ruling and other strategies the notice says are under examination.
The transaction the ruling addresses
The IRS ruling and notice describe a planned sequence: appreciated securities enter a newly formed ETF, and some or all of those securities then leave through an authorized participant’s redemption as part of the same plan. The ruling analyzes that sequence as a taxable exchange involving the contributing investor and the participant, rather than simply accepting its separate formal steps as a tax-deferred Section 351 contribution.
The notice also identifies other strategies for examination, including certain uses of box spreads. It does not declare every box spread or every ETF redemption improper. Its express limits and request for information are part of the document, not details to omit from a dramatic headline.
Why the sequence matters more than the label
Imagine a fictional investor contributing an appreciated portfolio to a new fund. If the fund is intended to retain assets consistent with its investment approach, that is a different factual picture from a prearranged process designed to move the contributed securities to another party and replace them.
Calling both arrangements a “351 conversion” does not establish that they have the same tax result. Timing, agreements, the assets retained, and the relationship among steps can matter. A reader cannot resolve those facts by recognizing the name of a tax-code section.
Morgan Lewis’s legal analysis explains the ruling’s use of substance-over-form and step-transaction principles. It also notes questions about application and the potential significance for earlier transactions. That is a law firm’s analysis of the guidance, not an individualized opinion approving a particular investor’s arrangement.
Ordinary fund plumbing is a separate issue
An in-kind redemption delivers assets instead of requiring the fund to sell everything for cash. That mechanism helps explain why ETFs can be tax-efficient at the fund level. It does not mean that every shareholder’s dividends, distributions, or eventual sale proceeds are free of tax.
Consider an illustrative fund holding securities with embedded gains. Avoiding a sale inside the fund can affect whether a gain is recognized there. A person who later sells their own ETF shares still has a separate transaction to analyze. Confusing the two levels turns a narrower structural feature into an unrealistic promise.
Trace a tax claim to a person and a transaction: the fund’s recognition of a gain is distinct from the shareholder’s sale of ETF shares. The broader guide to tax wrappers and account choice helps keep the account, investment and tax event separate.
A ruling and a notice do different work
Revenue Ruling 2026-20 states the IRS’s interpretation for its specified facts. Notice 2026-62 describes additional concerns and asks for comments and information. Treating the notice as a final prohibition on every described activity overstates it. Treating the ruling as merely an unofficial speech understates it.
Sullivan & Cromwell’s memorandum places the new guidance after the July discussion and emphasizes the described conversion structure. The distinction between the particular transaction and wider potential action is central to reading the update accurately.
For someone assessing a previous transaction, an interpretation of existing law can raise questions that differ from a new rule expressly limited to future dates. The appropriate response depends on the actual facts and professional advice. This companion cannot determine a filing position, penalty exposure, or the outcome of an examination.
Stress-test the investment without the advertised tax result
A fictional investor comparing two specialized funds could ask what each holds, what risks it takes, how much it costs, and whether it remains attractive if the expected tax treatment is challenged. That exercise separates the economic exposure from the benefit used to sell it.
The same investor should distinguish an ordinary broad-market holding from a complex planned conversion involving substantial appreciated assets. An update about the latter is not a reason to assume every conventional ETF has lost its normal mechanics.
Read the prospectus’s tax-risk discussion alongside the actual guidance. Keep “tax deferred,” “not recognized at the fund level,” and “not taxable to me” as separate claims requiring separate support. The change since July is real, but its significance comes from the precise transaction and documents, rather than a blanket claim that ETF tax efficiency has ended.
