Schwab tightens tax-aware SMA minimums to $10 million

Charles Schwab is tightening access to tax-aware long-short separately managed accounts for at least the third time, raising the asset minimum to $10 million from $1 million for some of the products and closing portfolio margin accounts to new clients and new money, changes spelled out in a client note obtained by Bloomberg that take effect on Sept. 16.

The strategy’s pitch is simple on paper: the account bets both for and against companies, and losses from the trades that go wrong are used to offset capital-gains taxes a client owes elsewhere. Over the past three years that pitch drew in affluent investors in volume, until Schwab and Fidelity, the two major firms that were facilitating the trade, both pulled back — Schwab in stages, Fidelity more abruptly.

Schwab’s letter frames the move as a capacity decision rather than a rejection of tax-loss harvesting, telling clients that “the current pace of growth of these strategies could limit our ability to support the full range of capabilities you and your clients rely upon from us.” A Schwab spokesperson said the firm regularly reviews its platform requirements and that the changes apply only to new accounts, leaving existing clients with no impact to their existing terms.

The tenfold minimum is the number RIAs should read twice, because at $1 million some of these long-short sleeves were available to clients with serious but not extraordinary wealth, while at $10 million the same sleeves sit in a different tier. Existing clients are grandfathered, but a new client with $2 million or $4 million will not clear the bar after Sept. 16.

Fidelity has gone further, indefinitely pausing new-client onboarding into the strategy while it evaluates what is driving growth, and Bloomberg has reported that some at Schwab worried the promise of tax elimination was pulling investors in before they fully understood the trade. Schwab had already twice restricted who could open new accounts and imposed borrowing and other limits, making this round an escalation of an existing pattern.

The portfolio margin piece is easy to treat as a footnote, but it deserves a closer look. Portfolio margin accounts use greater leverage and are not, by themselves, a tax product; banning new clients and new money in both areas at the same time suggests Schwab is reviewing a category of high-intensity accounts, beyond just one strategy. For RIAs, that widens the list of platform risks they have to monitor.

For an adviser, this is where the risk actually sits: the suitability work can be perfect and the client ideal, and a custodian can still reorganize the shelf with a client note. Tax-aware long-short SMAs are being moved upmarket by a tenfold minimum, so any RIA whose new-business pitch leans on that sleeve now has to carry the thresholds, the grandfathering rules, and the margin restrictions into the conversation.

Demand has not vanished with the restrictions: other money managers remain active in the space, and interest in tax-aware strategies is not going away. But the tax layer is becoming the product, as this publication noted when Orion wrapped BlackRock, Fidelity and Vanguard models in its tax engine. Schwab’s memo is the counterweight: a tax product only runs on custody rails, and rails have capacity limits.

Schwab’s call is rational: a platform that cannot support everything it has promised has to choose what to support first, and the note states the terms plainly. The cost, though, lands on advisors, because September 16 is a fixed date and the clients who need a new $1 million solution after it will be looking for an answer before it. The advisors with the most durable practices will treat the memo not as a product change but as a reminder that in custody, access is always a policy decision.
