Direct Indexing: Tax-Loss Harvesting Beyond Index Funds

Direct indexing means owning the individual stocks of an index directly in a separately managed account, rather than buying a pooled index fund or ETF that tracks the same index. The investor holds hundreds of individual positions, each with its own cost basis and its own price movement, rather than one pooled security representing the whole index.

Because each stock is owned separately, the account can sell specific stocks that are trading below their cost basis, realize the loss for tax purposes, and immediately replace them with a similar stock to maintain overall market exposure. This is the core distinction from an index fund: an index fund is a single security that either gains or loses as a whole, while direct indexing provides hundreds of independent tax events over the course of a year (see the Atlatl Advisers overview of direct indexing and tax-loss harvesting and Focus Planning Group's comparison of tax-loss harvesting in direct indexing versus a fund).

Under IRS Section 1091, a realized loss is disallowed if the investor buys the same security, or one that is "substantially identical," within 30 days before or after the sale, a 61-day window in total. Direct indexing managers generally work around this rule by replacing a sold stock with a different company that plays a similar role in the portfolio, for example swapping one large regional bank for another, so that market exposure is maintained without triggering a wash sale on the original position.

The replacement stock is typically held for at least 31 days, after which the manager may rotate back to the original stock if that still fits the portfolio's construction. The wash-sale rule also applies across all accounts owned by the investor and their spouse, including IRA accounts, so harvesting a loss in a taxable direct indexing account while simultaneously buying the same stock inside an IRA would trigger a wash sale and disallow the loss (see the Atlatl Advisers overview of direct indexing and tax-loss harvesting and CashCache's overview of direct indexing tax benefits for high-net-worth investors).

Direct indexing is typically offered through separately managed accounts with minimum investment thresholds. Common minimums run from $250,000 to $500,000 for basic direct indexing, and from $1 million to $5 million for more sophisticated versions that include long or short tax-aware extensions. Management fees for direct indexing typically range from 0.25% to 0.50% annually, on top of any underlying trading costs.

For the strategy to be worthwhile, the after-tax benefit it generates, sometimes described as tax alpha from harvested losses, needs to exceed the management fee charged for it. In smaller taxable accounts, that fee may exceed the tax benefit generated, which can make a plain index fund or ETF more cost-effective instead. The strategy generally becomes more attractive as account size increases, since the dollar value of harvested losses scales with assets while the fee percentage itself stays constant (see Keen Investors' overview of when direct indexing works for high-net-worth investors and Beancount's 2026 guide to direct indexing, tax-loss harvesting, and tracking error).

An index fund or ETF is a single security that tracks an index, generally at low cost, with expense ratios commonly in the 0.03% to 0.20% range, and it is simple to own. Its limitation for tax purposes is that losses can only be harvested when the fund itself declines as a whole, since there is no way to isolate and sell individual underlying stocks separately.

Direct indexing instead owns the individual stocks directly, at a higher cost, generally a 0.25% to 0.50% management fee, and with more complexity to manage. In exchange, it can harvest losses at the individual stock level even when the index overall is up, and it allows customization such as excluding specific stocks, applying ESG screens, or tilting toward particular factors, along with the ability to gradually diversify a concentrated stock position over time by using harvested losses to offset the gains realized along the way.

The primary advantage of direct indexing is tax efficiency: the after-tax return may be higher than an equivalent index fund even when the pre-tax return is identical, because harvested losses reduce the investor's tax bill along the way. The primary disadvantage is cost and complexity: the management fee needs to be justified by the tax benefit it produces, and the strategy generally requires a larger minimum investment than an index fund does. Our guide to tax-loss harvesting for high-income earners and our guide to RSU tax planning for medtech executives look at how these tax-loss harvesting concepts extend beyond direct indexing into broader portfolio and equity compensation planning.
