- Treasury and the IRS say prearranged ETF asset swaps can count as taxable exchanges under Section 1001.
- Ordinary seeding remains available when contributed assets fit the fund’s strategy and are expected to stay.
- The agencies invited comments on other fund strategies by October 28, 2026.
Treasury and the IRS issued new ETF tax guidance on September 28, 2026, treating a specified prearranged contribution-and-swap arrangement as a taxable exchange. Ordinary ETF seeding remains available when the contributed assets fit the fund’s investment strategy and are expected to stay there.
The agencies issued Revenue Ruling 2026-20 alongside Notice 2026-62. The ruling addresses a transaction in which an investor contributes appreciated securities to a newly formed ETF, then the fund redeems or exchanges those assets as part of a prearranged plan.

That sequence leaves the investor with a materially different portfolio without current gain recognition under the planned structure. Treasury and the IRS say the described transaction should instead be treated as a taxable exchange under Section 1001, based on its substance.
The notice covers a wider range of investment-fund strategies that may produce tax results inconsistent with federal tax rules. It also distinguishes those concerns from ordinary seeding that aligns with a fund’s investment thesis.
The ruling focuses on a prearranged change to the investor’s portfolio
The ruling’s example turns on the plan connecting the initial contribution to what happens next. An investor places appreciated securities in a newly created ETF, and the fund quickly redeems or exchanges assets under an arrangement already in place.
The subsequent portfolio is materially different from the one represented by the contributed securities. The described transaction therefore is not treated as a tax-free contribution followed by an unrelated change in holdings. The ruling characterizes the integrated arrangement as an exchange for tax purposes.
That treatment applies to the fact pattern the ruling addresses: a contribution followed by a planned asset shift that avoids current gain recognition while changing the investor’s portfolio. The guidance does not say that contributing appreciated securities to an ETF, by itself, produces the same result.
The distinction is between assets placed in a fund as part of its actual starting portfolio and assets used temporarily before a planned substitution. In the latter arrangement, the ETF functions as an intermediary in the move to another basket. The ruling treats that described sequence according to its economic substance.
The guidance gives no fixed holding period or percentage test
The notice leaves ordinary seeding in place when contributed assets match the ETF’s strategy and are intended and expected to remain in the fund. It allows for the possibility that circumstances may substantially change after the seeding.
The guidance is not framed around a stated number of days that assets must remain in the ETF, or a specified share of the portfolio that must be contributed. No mechanical holding-period test or fixed percentage threshold is identified for permissible seeding.
Instead, the relevant inquiry is based on the facts and circumstances. The purpose of the contribution, how the assets relate to the fund’s investment thesis, and whether a later portfolio change was prearranged help distinguish genuine seeding from a temporary placement.
A “seed then swap” plan aimed at deferring gain while replacing the contributed securities with a materially different portfolio falls within the ruling’s targeted fact pattern. By contrast, assets suited to the ETF’s stated strategy and expected to remain there are within the ordinary-seeding treatment described in the notice, unless circumstances substantially change.
The notice also seeks comments on other fund strategies
The notice raises concerns about multiple investment-fund strategies, not only the particular ETF transaction described in the ruling. It identifies the possibility that such strategies could generate tax outcomes inconsistent with federal rules, while expressly leaving ordinary, strategy-aligned ETF seeding outside its stated scope.
Treasury and the IRS requested public comments by October 28, 2026. The notice’s broader discussion and the ruling’s specific transaction are separate parts of the guidance: one flags a range of fund strategies for comment, while the other addresses the tax treatment of its described contribution-and-exchange arrangement.
Ordinary seeding can still be used when the assets belong in the fund and are expected to remain there. The public comment period closes October 28, 2026.
