Frequently Asked Questions About Section 351 Exchanges
Section 351 exchanges are becoming an increasingly relevant tool for investors, families, and advisors looking to diversify concentrated stock positions while managing tax impact.
Common questions include:
- Will a Section 351 exchange work for my situation or my client’s portfolio?
- What happens to taxes, now and over time?
- How does the Section 351 exchange ETF fit into the overall strategy?
Below are answers to the most common questions about Section 351 exchanges we hear, from high-level considerations to more technical details, to help you assess whether this approach may be a fit.
1. Eligibility & Suitability
A Section 351 exchange is typically a good fit for investors or clients who hold concentrated stock positions with significant unrealized gains and want to diversify without triggering immediate capital gains.
Whether a portfolio qualifies depends on how it is constructed and whether it meets diversification requirements.

The Section 351 exchange ETF is designed primarily for publicly traded equities. Mutual funds and certain private or non-traded assets are generally not eligible. Short-term gain positions may be contributed, but tax implications should be reviewed carefully.

In most cases, no, an investor in a single stock position cannot use a 351 exchange. To qualify for tax deferral, the portfolio must meet diversification thresholds, including:
- Limits on any single position
- Limits on concentration across top holdings

No, there is generally no lock-up period or loss of liquidity in a Section 351 exchange. Unlike exchange funds, ETF shares are typically liquid after launch and can be traded daily.

2. How It Works
At a high level, here is what actually happens in a Section 351 exchange:
- The investor contributes appreciated securities into a newly launched ETF
- The investor receives ETF shares in return
- Capital gains are deferred at the time of transfer, if requirements are met
In a Section 351 exchange, the investor receives shares of the ETF, representing ownership in a diversified portfolio rather than individual securities.
At launch, the Section 351 exchange ETF may initially reflect the contributed holdings. Over time, however, the portfolio is repositioned into a defined investment strategy, creating broader diversification.
In some cases, yes, a portfolio may be split across multiple strategies or ETFs in a Section 351 exchange. This typically requires separate exchanges and depends on structure and timing.
3. Tax Treatment
The Section 351 exchange strategy defers taxes. It does not eliminate taxes.
Capital gains are not recognized at the time of the exchange but are realized when ETF shares are eventually sold.
After a Section 351 exchange, the investor’s original cost basis and holding period carry over into the ETF shares.
In a Section 351 exchange, when ETF shares are sold, taxes are based on:
- The carried-over cost basis
- The portion of the position being sold
Generally, no, a Section 351 exchange will not create any ongoing tax inefficiencies such as “tax drag.” In many cases, it may improve tax efficiency over time.
Tax drag refers to the impact of ongoing taxable distributions reducing returns over time. When gains are taxed annually, less capital remains invested and compounding.
ETF structures are typically more tax-efficient. Through in-kind creation and redemption, ETFs can help reduce the frequency of taxable distributions and allow investors to control when gains are realized.
As a result, a Section 351 exchange not only defers taxes at the time of transition but may also support more tax-efficient compounding over the long term.
4. Risks & Considerations
The Section 351 exchange could become taxable if it does not meet IRS requirements at the time of contribution.
To qualify for tax deferral, the portfolio must meet specific rules, most importantly, diversification requirements.
The exchange may not be treated as taxable if:
- The portfolio is too concentrated
- The transaction is not properly structured or documented
- The contribution does not meet Section 351 requirements
Once completed correctly, normal market movements do not cause the exchange to become taxable.

If the contribution does not meet IRS requirements, the transaction may be treated as a taxable event.
Yes, future tax law changes could impact this strategy. Section 351 has long-standing precedent, but tax rules can evolve. Investors should consult their tax advisors.
5. Costs & Alternatives
Costs typically include:
- ETF expenses
- structuring and operational costs
Compared to alternatives:
- Exchange funds often involve lock-ups
- Hedging strategies reduce risk but generally do not diversify
- Direct indexing requires ongoing management
A Section 351 exchange has potential to provide:
- diversification
- tax deferral
- liquidity

6. Common Misconceptions
A Section 351 exchange does not eliminate taxes. It defers them until a future sale.
A Section 351 exchange only works for portfolios that meet specific diversification requirements.
A Section 351 exchange is not the same as an exchange fund. Exchange funds typically have lock-ups, while ETFs provide daily liquidity.
Through a Section 351 exchange, the portfolio is repositioned into a diversified strategy over time.
In a Section 351 exchange, tax deferral is the starting point. Long-term outcomes depend on how the capital is reinvested and compounded.
7. Advanced Considerations
Yes, short-term gain assets can be contributed to a Section 351 exchange, but tax treatment depends on the investor’s situation and should be reviewed carefully.
In many cases, yes, ADRs may be contributed to a Section 351 exchange, but it depends on how the ADR is treated relative to the underlying shares.
ADRs are U.S.-traded securities that represent shares in a foreign company. Whether they can be contributed in a Section 351 exchange depends on whether the ADR and the underlying ordinary shares are considered equivalent for tax and structural purposes.
Because this determination can vary based on the specific security and ETF structure, ADR eligibility is typically reviewed on a case-by-case basis as part of the portfolio assessment process.

In some cases, ETFs can be contributed into another Section 351 ETF, but this depends on structure and eligibility.
Proper structuring, documentation, and coordination with tax professionals are essential in a Section 351 exchange.
