For professionals and investors sitting on highly appreciated assets, transferring or repositioning those assets can trigger one of the most substantial tax bills of their financial life. This is a challenge familiar to many Bay Area professionals who have accumulated significant wealth through restricted stock units (RSUs), employee stock purchase plans (ESPPs), or long-tenured equity awards, as well as business owners looking to restructure appreciated assets. Section 351 of the Internal Revenue Code (IRC) is a provision that may allow that repositioning to happen without recognizing a taxable gain at the time of contribution, and the strategy has gained meaningful new relevance with a growing application involving exchange-traded funds (ETFs).

How Does a Section 351 Exchange Work?

Section 351 allows individuals or entities to contribute property, including appreciated securities such as stocks, bonds, and ETFs, to a corporation in exchange for stock without triggering an immediate taxable gain. The contributing party carries over their original cost basis into the shares received rather than recognizing the embedded gain at transfer. That gain is deferred, not eliminated, and becomes taxable when the shares are eventually sold. For the exchange to qualify, the contributing party or group must generally meet specific IRS control requirements immediately after the transfer.

Can Section 351 Be Used to Contribute Appreciated Stock Into an ETF?

This is where the strategy may be particularly relevant for tech professionals and investors managing multiple appreciated equity positions. An ETF is a pooled investment vehicle that holds a basket of securities and trades on a stock exchange. Section 351 can be used to contribute a diversified basket of appreciated securities into a newly formed ETF in exchange for ETF shares, with the embedded capital gains generally deferred in the process, allowing the investor to transition into a more diversified structure without an immediate tax cost.

A key eligibility requirement is that the contributed portfolio must already be reasonably diversified under IRS guidelines, taking into account both individual position sizes and overall concentration. This makes the strategy more applicable to those who have built up multiple appreciated positions over time than to those holding a single concentrated stock. Not all asset types qualify, and meaningful minimum asset levels are generally required for the economics to make sense.

What Should California Residents Know about 351 Exchanges?

California generally conforms to the federal Section 351 nonrecognition rules, meaning the gain deferral may apply at the state level as well in most cases. Any future sale of the shares or ETF interests received will be subject to California’s capital gains rate, which taxes gains as ordinary income with no preferential long-term rate. For high earners, the combined federal and California tax burden can be substantial, making the structure and timing of any eventual disposition an important part of the planning conversation from the start.

Key Requirements and Risks to Understand

• The contributing party must meet IRS control requirements immediately after the transfer, which affects how the transaction is structured
• ETF exchanges must satisfy IRS diversification requirements, and not all asset types or portfolio structures qualify
• Shares received in exchange for services rendered do not qualify for nonrecognition treatment and are generally taxable as ordinary income
• Receiving anything other than stock in return, such as cash or debt relief, may trigger a taxable event at the time of the exchange
• Certain ETF exchange structures have drawn increased scrutiny from the IRS and Treasury, making legal and tax counsel essential before moving forward

Who Might Consider a Section 351 Exchange?
