Direct Indexing in 2026: Costs, Tax-Loss Harvesting Math, and Who Should Skip It

Direct indexing means owning the stocks in an index yourself instead of owning a fund that holds them. Software buys a few hundred stocks in roughly index weights, then sells individual positions when they fall to harvest tax losses, replacing them with similar stocks so the portfolio still tracks the index. It used to require a private bank and a seven-figure account. In 2026 several brokers offer it from $5,000.

The appeal is real, but so are the limits. Much of the tax benefit is a deferral, the fee is several times that of an index ETF, and the harvesting opportunities shrink as the portfolio ages. This guide covers the current costs, the tax math, the traps, and who is better off with a plain ETF. For the wider set of tax strategies, see our tax-efficient investing guide.

How it works

In a fund, losses on individual stocks stay inside the fund and cannot reach your tax return. Owning the stocks directly changes that. Even in a year when the S&P 500 rises, dozens of its members fall, and each of those losses can be realized and used.

A direct indexing account typically does three things:

1. Harvests losses. When a stock falls below its purchase price by a set threshold, the software sells it and buys a similar stock, often from the same industry, to keep the portfolio's exposure. See our tax-loss harvesting guide for the rules in detail.
2. Applies exclusions. You can leave out your employer's stock, a sector, or companies that conflict with your values. Our ESG investing guide covers values-based screens.
3. Tilts, if you ask. Some platforms let you overweight factors such as value or quality; see our factor investing guide.

What it costs in 2026

Fees and minimums as of September 2026; they have been falling, so check current pages. Advisors can also offer direct indexing through firms such as Parametric and Aperio, usually with their own advisory fee on top.

An illustration: the fee hurdle

On a $500,000 account, a 0.40% fee costs $2,000 a year against $150 for a 0.03% ETF. The $1,850 difference means the strategy has to add about 0.37% a year after tax just to break even. At 0.09%, the extra cost is $300 a year, a hurdle of about 0.06%. The lower-cost platforms have changed the arithmetic more than any tax rule has.

How much tax does it save?

A study by Chaudhuri, Burnham, and Lo in the Financial Analysts Journal (2020) simulated loss harvesting on the 500 largest US stocks from 1926 to 2018. With long-term and short-term tax rates of 15% and 35%, it estimated tax alpha of 1.08% a year before transaction costs, and 0.82% a year once the wash sale rule was applied. Results vary with market conditions: volatile years produce more losses to harvest.

Two things shrink that number in practice.

Deferral is not elimination. Each harvested loss lowers your cost basis by the same amount, so the tax comes back when you sell. The saving becomes permanent only if you hold until death, when heirs receive a stepped-up basis, or donate the appreciated shares to charity.

Lock-in. In the first year or two, many positions trade below cost and harvesting is frequent. As the market rises, most positions carry gains and there is little left to harvest. The account also becomes costly to leave, because selling it or moving to another manager that wants to rebuild the portfolio would realize those gains. Transfer in kind if you switch.

An illustration: one year of harvesting

A single filer in the top bracket (2026 long-term capital gains rate of 20% plus the 3.8% net investment income tax) sells a rental property with a $37,000 long-term gain. The direct indexing account harvests $40,000 of losses the same year.

• $37,000 of losses offset the property gain: $37,000 × 23.8% = $8,806 saved.
• The remaining $3,000 offsets ordinary income at 37%: $1,110 saved. Losses beyond that carry forward indefinitely.
• Total tax saved this year: $9,916.

The account's basis is now $40,000 lower. If the investor later sells at the same 23.8% rate, $9,520 comes due, so the true gain is the use of the money in the meantime plus about $396 of rate difference on the $3,000 deducted against ordinary income. If the shares are held until death or given to charity, the deferred tax is never paid. Rates and brackets come from IRS Revenue Procedure 2025-32; our capital gains tax guide covers them in full.

Wash sales across your other accounts

A loss is disallowed if you buy the same or a substantially identical security within 30 days before or after the sale, and that window covers every account you control, including a spouse's. The platform can only see its own account. Common ways to trip it:

• Dividend reinvestment in another brokerage account that buys a stock the direct index just sold
• Individual stocks held elsewhere, or bought through an employee stock purchase plan
• Buying the stock in an IRA or Roth IRA, which under Revenue Ruling 2008-5 disallows the loss permanently and gives no basis increase in the IRA
• Two direct indexing accounts at different firms harvesting against each other

A disallowed loss in a taxable account is added to the basis of the replacement shares, so it is deferred; the IRA case is the one where it disappears. IRS Publication 550 has the full rules. Turn off dividend reinvestment elsewhere, and give the platform your restricted list.

Replacement trades also create tracking error. While a harvested stock is out of the portfolio, the substitute may perform differently, and if the substitute is later sold at a gain within a year, that gain is short-term.

Who it suits and who should skip it

It suits investors who:

• Pay high marginal rates and expect regular capital gains from real estate, a business sale, private funds, or concentrated stock
• Have a large taxable account they expect to hold for many years, or to leave to heirs
• Give to charity, since the most appreciated lots can be donated instead of cash
• Need to exclude an employer's stock or a sector

It is a poor fit for investors who:

• Fall in the 0% long-term capital gains bracket (in 2026, taxable income up to $49,450 single or $98,900 married filing jointly)
• Invest mainly through IRAs and 401(k)s
• Expect to spend the money within a few years, which would realize the deferred gains
• Do not want a tax return with hundreds of lines on Form 8949

Concentrated stock: related options

Direct indexing can diversify a concentrated position slowly, using harvested losses to offset gains from selling a bit of the stock each year. Two other routes are worth knowing:

• Long-short (tax-aware) strategies add borrowed short positions to generate more losses. Frec, for example, offers one from $100,000 at 0.50%. They carry more risk and complexity.
• Section 351 exchange ETFs let investors contribute appreciated securities to a newly launched ETF without immediate tax, with basis and holding period carried over. The contribution must pass a diversification test: no single issuer over 25% of what you contribute, and the top five no more than 50%. A single large stock usually fails unless combined with other holdings. Kitces explains the mechanics, and Morningstar has covered the IRS risk of aggressive structures.

Getting started

1. Estimate the capital gains and ordinary income you expect over the next few years, and your marginal rates.
2. Choose the index: S&P 500 for most people, a total market index for broader exposure.
3. List exclusions, including your employer's stock and any stock held in other accounts.
4. Compare fees and minimums; for a plain index with harvesting, the lowest-cost platforms are hard to beat.
5. Transfer existing shares in kind where possible, so setting up does not trigger gains.
6. Turn off dividend reinvestment in other accounts and keep your restricted list current.
7. Each year, compare the tax saved with the extra fee, and remember the deferred tax built into the lower basis.
