A client asked:
“If there ever comes a day where I want to retire from trading individual stocks and just be exposed to the S&P 500, is there a way to ‘swap’ into that without triggering gains?”
Section 351 conversions can be a great solution for situations like this.
Conceptually, it’s somewhat similar to a 1031 exchange in real estate, allowing investors to defer capital gains taxes while transitioning into a different structure.
With a 351 conversion, appreciated stock and ETF holdings can potentially be contributed to seed a new ETF, which may allow for:
- broader diversification
- reduced single-stock risk
- lower maintenance
- and continued tax deferral
Another perk - a diversified portfolio is generally much better-behaved collateral for portfolio-based financing
351 conversion → box spread loan can be a very powerful combination for investors looking to maintain liquidity while continuing to defer taxes.
So if you’re:
- sitting on a large low-basis stock/ETF portfolio,
- wanting to simplify into something closer to S&P-style exposure,
- and trying to avoid writing a massive check to the IRS in the process,
a 351 structure may be worth exploring.
