A specified plan that moves appreciated securities into a new exchange-traded fund and then out to another participant can be treated as a taxable exchange, according to IRS Revenue Ruling 2026-20. The practical warning is about the transaction’s combined economic substance—not a blanket tax on owning ETFs.
This is an explainer of guidance reproduced in Internal Revenue Bulletin 2026-43, dated October 19, 2026. It is not a claim that a new tax was enacted today. The bulletin’s ruling and its separate request for comments do different things.
Which transaction does the ruling address?
In the stated facts, an investor contributes a portfolio with unrealized gains to a newly formed ETF. Under the same plan, an authorized participant exchanges securities or cash for ETF shares and shortly afterward redeems those shares for securities the investor contributed. The ETF ends up holding a materially different portfolio aligned with its investment thesis.
The IRS treats the fund as an intermediary in that planned exchange. For tax purposes, the investor is treated as exchanging those contributed securities with the authorized participant, rather than making a qualifying Section 351 contribution to the ETF. The ruling says the result is the same with multiple contributing investors.

Why “tax-free conversion” needs careful qualification
Section 351 can provide nonrecognition treatment when its requirements are met. The ruling applies substance-over-form and step-transaction principles to its particular facts. Combining formally separate steps does not automatically preserve the tax treatment asserted for each step in isolation.
It would therefore be inaccurate to turn this ruling into “all ETF contributions are taxable,” or to imply that a request for comments has already finalized every possible rule discussed in the notice. The bulletin itself cautions against applying ruling conclusions to materially different circumstances.
