351 Exchanges: SMA-to-ETF Transitions
We help prospective clients convert existing portfolios into ETFs using a Section 351 exchange. This strategy preserves tax efficiency, simplifies operations, and scales your investment approach without triggering unnecessary capital gains. Our team provides the structuring guidance, regulatory coordination, and operational support required to execute 351 exchanges with precision and confidence.
What Is a 351 Conversion?
A 351 conversion is a tax-deferred transaction under the Internal Revenue Code that allows investors to contribute a diversified portfolio of securities to a newly formed corporation (in this case, an ETF) in exchange for shares without recognizing gain or loss.
This approach is typically used by RIAs, family offices, and asset managers who hold low-cost-basis securities and want to transition into an ETF structure. Instead of selling positions and triggering capital gains, a 351 tax free exchange allows the investor to contribute the portfolio to the ETF in-kind. The tax basis carries forward, and no realization event occurs at the time of the exchange.
The 351 tax-free exchange preserves portfolio continuity while enabling access to the operational and distribution benefits of the ETF structure. It’s particularly valuable for clients managing concentrated or highly appreciated portfolios who need scalability without tax acceleration.
Why Clients Convert SMAs Into ETFs
White label services offer expedited avenues guiding opportunities from concept to launch. Sourcing and establishing relationships with ETF service providers can take time, so engaging white-label platforms with operational infrastructure and existing systems streamlines the launch process.
Gain access to pre-existing relationships and processes supporting products without the burden of building these capabilities from scratch. White label providers maintain relationships with fund administrators, legal counsel, and market makers that would otherwise require pre-existing relationships or significant due diligence to establish.
By partnering with a white label provider, portfolio managers and investment professionals can concentrate on what they do best, such as developing investment strategies and managing portfolios, rather than dealing with the complexities of ETF operations, regulatory compliance, and service provider coordination.
Launching an ETF independently requires substantial capital investment in legal, compliance, technology, and staffing infrastructure. White label services provide access to these resources at a fraction of the cost, allowing issuers to allocate capital toward investment strategy and business development rather than back-office buildout.
351 Exchange
Requirements
Executing a valid 351 conversion requires careful attention to IRS regulations. The transaction must meet specific structural and ownership thresholds to qualify as tax-free.
80% Control Rule
Immediately after the exchange, the transferor must own at least 80% of the total combined voting power and 80% of each class of nonvoting stock. This ensures the transaction qualifies under Section 351 and avoids immediate tax recognition.
Diversification Standards
The IRS imposes diversification requirements on regulated investment companies (RICs), including ETFs. Portfolios must meet these standards at the time of conversion. Concentrated positions or single-issuer exposure above regulatory limits may require restructuring before the exchange.
Portfolio Eligibility Considerations
The portfolio being transferred must align with the investment mandate of the receiving ETF. Assets that fall outside the fund’s stated strategy or violate compliance restrictions cannot be included in the exchange.
Pre-Conversion Analysis
We conduct a detailed review of portfolio composition, cost basis data, and regulatory alignment before initiating the 351 exchange. This ensures the transaction is structured correctly and meets all 351 exchange requirements from the outset.
How Sound Capital Approaches 351 Conversions
Our methodology is consultative and portfolio-first. We don’t offer a standardized conversion product. Instead, we assess your specific holdings, tax profile, and strategic goals, then design a solution tailored to your needs.
Portfolio Review & Diversification Analysis
We analyze your existing SMA holdings to identify any diversification or regulatory issues that could affect eligibility. If restructuring is required, we provide guidance on how to address it without disrupting the core strategy.
Structuring Guidance
We help you determine the optimal ETF structure, whether that’s a new fund or an existing vehicle. Our open-architecture approach means we’re focused on the right solution for your situation, not a predetermined product.
Recordkeeping Considerations
Accurate cost basis tracking is critical to a successful 351 conversion. We work with your custodian and tax advisors to ensure all records are in order and the exchange is documented correctly for IRS compliance.
Regulatory and Operational Coordination
We coordinate with legal counsel, fund administrators, authorized participants, and market makers to manage the regulatory filings, operational setup, and launch execution required for the ETF.
Launch Execution Oversight
We oversee the initial exchange, monitor first creations, and ensure the transition from SMA to ETF is executed smoothly. Our team has extensive experience managing SMA-to-ETF conversions for institutional clients.
Who Should Consider a 351 Conversion?
A 351 conversion is best suited for:
- RIAs with large low-basis SMAs seeking tax-efficient portfolio transitions
- Family offices managing taxable portfolios looking to consolidate operations and reduce administrative complexity
- Asset managers seeking ETF structures who want to scale their strategy without liquidating existing positions
- Firms with scalable strategies that benefit from the liquidity, transparency, and distribution advantages of the ETF format
If you manage concentrated or appreciated portfolios and need operational flexibility without triggering capital gains, a Section 351 exchange may be worth exploring.
