Direct Indexing for High-Income Earners

Direct indexing's tax benefit scales with your capital gains tax rate. For investors in the top federal bracket, the 23.8% combined LTCG+NIIT rate means every harvested dollar saves nearly one-quarter in taxes — more if you're in California, New York, or another high-rate state. Here's how high-income investors use direct indexing differently from everyone else.

Why your tax rate is the single most important variable

The mechanics of tax-loss harvesting are the same regardless of your income: the platform harvests individual stock losses daily and uses them to offset capital gains. But the dollar value of each harvested loss is a direct function of your tax rate on capital gains.

For investors with taxable income above $545,500 (single) or $613,700 (MFJ) in 2026, long-term capital gains are taxed at 20%.¹ Add the 3.8% Net Investment Income Tax (NIIT), which applies above $200,000 single / $250,000 MFJ and is not adjusted for inflation,² and the combined federal rate on long-term gains is 23.8%.

At a $2M taxable account with a 1.5% annual harvest rate — consistent with actively managed harvesting in a moderately volatile market — direct indexing generates roughly $30,000 in harvested losses per year. Against a fee premium of ~$5,000/year (0.25% over a low-cost ETF), the net federal-only benefit at 23.8% is approximately $2,140 per year. At the 15% rate, it would be slightly negative. Tax bracket changes the sign of the result, not just the magnitude.

What direct indexing actually offsets — and what it doesn't

This is the most common misconception among high earners: capital losses from tax-loss harvesting offset capital gains, not ordinary income.

Under IRC § 1211(b), individuals can deduct up to $3,000/year of net capital losses against ordinary income; excess losses carry forward indefinitely.³ The $3,000 cap means a $60,000 loss bank has essentially no direct benefit against your W-2 salary, K-1 ordinary income, or RSU vesting income.

Where the loss bank pays off is against capital gain events:

• Selling appreciated ETFs or individual stocks
• Selling RSU or ESPP shares that have appreciated after the vesting date
• Real estate gain recognition (above primary-residence exclusion)
• Business or partnership interest sales that generate capital gains
• Mutual fund year-end capital gain distributions

If your high income comes entirely from W-2, 1099, or K-1 ordinary income — and you're not recognizing capital gains in the same year — a large loss bank is less immediately useful. The strategy still works, but it requires pairing the loss bank with planned capital gain events.

Income event coordination: the key to getting full value

High-income investors typically have predictable capital gain events on a multi-year horizon. A specialist uses this calendar to time when the loss bank is deployed for maximum impact.

RSU vesting and sales

RSUs vest as ordinary income at the share price on the vesting date — that portion is not offset by capital losses. But after vesting, shares held for more than one year generate long-term capital gains when sold. Executives who hold RSUs 12+ months before selling accumulate taxable gains at 23.8% (federal). A direct-indexed portfolio running parallel to the RSU position can accumulate losses that offset those gains at sale time.

The timing matters: establish the DI account one to two years before planned RSU sales, so the loss bank has time to build. Trying to harvest losses the same quarter you're selling shares is less effective than entering the event with an existing loss bank.

K-1 ordinary income and capital gain allocations

Partners in private equity funds, hedge funds, and real estate partnerships often receive K-1 allocations with a mix of ordinary income (management fees passed through, short-term gains) and long-term capital gains (carried interest, long-term gain pass-throughs). The long-term capital gain component — often substantial in fund exit years — is the part the DI loss bank directly offsets.

Fund exit years, when LPs receive back capital plus long-term gain allocations, are the highest-value times to hold a well-developed loss bank. A specialist who understands both the K-1 timing and the DI portfolio can coordinate the gain-realization year with peak harvest deployment.

Planned business or investment asset sales

If you're planning to sell appreciated real estate, a business with capital gain character, or a large stock position in the next few years, direct indexing provides the cleanest path to pre-positioning a loss bank. At $2M in a DI account, 1.5% annual harvest generates ~$30K/year in losses. Two years of accumulation = $60K loss bank before the sale.

The state tax multiplier

California, New York, New Jersey, and Oregon treat long-term capital gains as ordinary income — there is no preferential state rate on LTCG. That means the state rate stacks fully on top of the federal 23.8%:

A California resident in the top bracket paying $11,130 in tax savings against a $5,000 annual fee premium has a 2.2× net-benefit ratio. The same account in Texas produces 1.4×. Both are positive — but the California case is substantially more compelling. If you're in a high-tax state, a generic "is direct indexing worth it?" analysis understates your benefit by 50–60%.

Worked example: Executive in California

The scenario: Sarah is a technology executive in the Bay Area with $2.2M in taxable investments (mostly concentrated in tech ETFs from years of 401(k) maxing plus after-tax contributions). She has $800K in W-2 income plus an additional $300K in RSUs vesting annually. She's held some of those RSU shares for 15+ months and is planning to sell $250,000 worth over the next year.

Without direct indexing: $250,000 in LTCG × 37.1% combined federal+state rate = $92,750 in capital gains tax on those RSU sales.

With a DI account started 18 months earlier: $2.2M × 1.5% harvest/year × 1.5 years ≈ $49,500 in accumulated losses. Offsetting $49,500 of the $250,000 gain reduces taxable capital gains to $200,500. Capital gains tax: $200,500 × 37.1% = $74,386. Tax savings: $18,364.

DI fee cost over 18 months: $2.2M × 0.25% × 1.5 = $8,250.

Net after-fee benefit: $18,364 − $8,250 = $10,114 in year one — not counting ongoing annual harvesting benefit.

In year two, with the account at similar size, the $30,000+ annual harvest continues to run. Over a 10-year horizon, assuming declining harvest rates (markets trend up long-term), the cumulative tax alpha for a California investor at this account size is typically well into the six-figure range net of fees.

When high income isn't enough — the cases where DI still doesn't pay

High income is necessary but not sufficient for direct indexing to make sense. Two situations where it still doesn't work even at top tax rates:

You're a pure buy-and-hold investor with no planned sales

If you genuinely plan to hold your taxable portfolio for 30+ years and never sell — donating appreciated shares to charity or passing the portfolio with a stepped-up basis at death — you won't realize the capital gains that the loss bank would offset. In that case, the losses accumulate but never deploy, and the fee premium is a net cost. The DI account makes more sense for investors who plan to sell assets during their lifetime.

Your taxable account is small relative to your income

If your income is $800K/year but your taxable account is $150K, the annual harvest at 1.5% is only $2,250 — barely covering the minimum fee at most platforms. High income alone doesn't substitute for scale in the taxable account. The breakeven requires both: top tax rates and sufficient taxable assets to harvest meaningfully.

Starting before the gain event

The most common mistake high earners make with direct indexing is waiting until the year of a liquidity event (a business sale, RSU acceleration, planned real estate sale) to set it up. By that point, it's too late to build a meaningful loss bank. Harvesting takes time — a well-managed $2M account typically builds its most valuable losses in the first 18–24 months, when most positions are near their initial cost basis.

The right decision point is when you can see the gain event on the horizon but haven't yet reached it. Two to three years before a planned business sale, at the beginning of a multi-year RSU vesting schedule, when you first move to a high-tax state — those are the optimal moments to start.
