Direct Indexing for Trust Accounts

Non-grantor irrevocable trusts are taxed at dramatically compressed brackets — the 37% ordinary income rate and 23.8% combined LTCG+NIIT rate both apply at roughly $16,000 of income in 2026. That makes every dollar of tax-loss harvesting worth 59% more than in a typical individual account. This guide explains the mechanics, the 2026 trust tax numbers, the grantor/non-grantor distinction that determines whether the strategy applies, and three ways trustees can deploy direct indexing to reduce trust-level taxes.

2026 tax brackets for trusts and estates

Non-grantor trusts that file Form 1041 are taxed as separate entities with their own — dramatically compressed — bracket schedule. Here are the 2026 brackets alongside individual rates for comparison.¹

Sources: IRS Rev. Proc. 2025-32 (trust ordinary income brackets); IRS Publication 550 (trust LTCG rates); IRC § 1411 (NIIT).

Grantor trust vs. non-grantor trust: does the strategy apply?

This is the threshold question. Only non-grantor trusts face the compressed bracket — grantor trusts are entirely irrelevant to this analysis.

Bottom line: The compressed-bracket advantage applies to non-grantor irrevocable trusts that retain capital gains rather than distributing them to beneficiaries. Complex accumulation trusts, dynasty trusts, and multi-generational wealth trusts designed to accumulate inside the trust are the primary candidates.

Why TLH alpha is worth more in a trust

Direct indexing generates tax-loss harvesting alpha by realizing losses on individual stock positions (not the overall portfolio) to offset capital gains. The value of each dollar of realized loss equals the marginal tax rate at which it offsets gains.

The key insight: a non-grantor trust at $1M in equity reaches the 23.8% rate immediately, on the first dollar of long-term capital gain above $16,250. An individual with the same $1M portfolio might be in the 15% LTCG bracket. That gap — 23.8% vs. 15% — means every dollar of DI loss inside the trust is worth $0.238 vs. $0.150, or 59% more tax alpha per dollar of loss.

Add state taxes for trusts in California (13.3%), New York (10.9%), or New Jersey (10.75%) and the combined marginal rate on trust capital gains exceeds 37%. At 37.1% combined (CA), a $10,000 DI loss is worth $3,710.

Three strategies for trustees

Worked example: complex accumulation trust, Massachusetts family

Profile: A Massachusetts family's irrevocable complex trust, established for estate planning. Trustee is an independent corporate trustee. Trust holds $1.5M in equity (currently in Vanguard Total Market ETF, VTI). Trust retains all income (no income beneficiaries). Trust document does not include capital gains in DNI.

The tax problem: The trust's $1.5M equity is appreciating. If the trustee decides to reallocate — sell VTI to fund a different allocation — or if the trust receives any capital gain distributions, every dollar above $16,250 is taxed at 23.8% federal (plus 5% Massachusetts state tax = 28.8% combined).

Option A: Keep VTI — no action

ETF holds appreciated positions. Capital gain distributions from VTI in 2026: approximately $7,500 (0.5% distribution rate × $1.5M). Federal + MA tax: $7,500 × 28.8% = $2,160.

Option B: Convert to direct indexing — 3-year horizon

Transition the $1.5M from VTI to a Parametric direct indexing SMA. Initial cost: VTI has embedded gains of ~$200,000 from appreciation since purchase. Trustee chooses in-kind transfer to minimize initial tax event. Over 3 years:

Year 3 capital event: The trust sells a piece of commercial real estate. Net §1231 long-term gain attributed to the trust: $150,000.

The $19,440 tax saving in year 3 alone exceeds the typical DI platform fee of $3,000–$5,000/year for a $1.5M account. In addition, TLH alpha continues generating annually — the loss bank replenishes and is available for future gain events.

Distribution planning: can you distribute gains to beneficiaries?

Trustee's first question: can the trust distribute capital gains to beneficiaries at lower individual rates, rather than accumulating at trust rates?

The statutory default: Capital gains are allocated to principal (corpus) under the Uniform Principal and Income Act (UPIA) and most state law. Under IRC § 643(a), gains allocated to principal are excluded from distributable net income (DNI) unless an exception applies. Without DNI inclusion, the trust cannot deduct a distribution of those gains, and beneficiaries do not include them in income — the trust pays the tax at trust rates.

When gains can be included in DNI:

• The trust document explicitly includes capital gains in the definition of income available for distribution
• The trustee exercises a discretionary power under local law to allocate gains to income
• The trustee actually distributes capital gains to beneficiaries (not just maintains the ability to)

If your trust document allows this and your beneficiaries are in the 15% LTCG bracket, distributing $150,000 of capital gains to beneficiaries saves: ($150,000 × 23.8%) − ($150,000 × 18.8%) = $7,500 in federal tax alone compared to the trust paying. This is separate from DI — it's a document review question for the trust attorney before any DI strategy is deployed.

The interaction: If gains can be distributed (reducing the trust's tax exposure), DI is still valuable for the losses it generates — but the marginal value of each loss is lower if the effective trust rate on gains falls from 23.8% to 18.8% (if gains flow to beneficiaries in the top 15% bracket). Best practice: review distribution flexibility first, then model DI on the gains the trust will retain.

Platform considerations for trust accounts

Critical trust-specific issue — wash-sale contamination: If the grantor or a beneficiary holds substantially identical positions in their personal brokerage or IRA account, the DI trust account's harvested losses can be disallowed under IRC § 1091. The IRS wash-sale rule applies across all accounts owned by the same taxpayer — and depending on the trust structure and grantor attribution rules, the trust's holdings may be attributed to the grantor. An advisor-managed platform that monitors all related accounts is essential for non-grantor trust DI to actually deliver the harvested losses.

Questions to ask before implementing DI in a trust

1. Is this a grantor trust or a non-grantor trust? The compressed-bracket advantage only applies to non-grantor trusts. Have the trustee or trust attorney confirm the tax classification before modeling any DI benefit.
2. Does the trust document permit capital gains to be included in DNI? Distributing gains to beneficiaries at lower individual rates may be more valuable than DI — or they may be complementary. The document review comes first.
3. What are the related accounts for wash-sale purposes? Identify every account the grantor, trustee, or beneficiary controls that holds similar equity positions. The DI platform's wash-sale monitoring must cover all of them.
4. What is the trust's investment policy statement (IPS)? Many institutional trusts have mandatory diversification requirements, prohibited asset lists, and asset allocation constraints. The DI platform must be able to operate within those constraints.
5. What is the expected timing of large gain events? The pre-event loss bank strategy requires 12–36 months of accumulation ahead of a known realization. If a gain event is imminent, the DI account may not have time to build enough losses to matter.

Does direct indexing work inside a trust account?

Yes. Advisor-managed platforms — Parametric, Aperio, Vanguard Personalized Indexing — routinely manage direct indexing accounts held in trust. The trust provides its EIN, trust agreement, and trustee documentation. Once funded, the DI account operates identically to an individual account, harvesting losses that reduce the trust's taxable capital gains at the compressed trust bracket rates.

Why is TLH more valuable in a trust than in an individual account?

Because non-grantor trusts face the 20% LTCG rate plus 3.8% NIIT — a combined 23.8% — beginning at just $16,250 of income (2026). Most individual investors in a similar wealth range are in the 15% LTCG bracket. Every $10,000 of harvested losses saves $2,380 in trust vs. $1,500 at the individual 15% rate. That's 59% more tax alpha per dollar of loss.

What is the difference between a grantor trust and a non-grantor trust?

Grantor trusts (revocable living trusts, many IDGTs, some SLATs) are disregarded for income tax purposes — all income is taxed at the grantor's individual rates. The compressed trust bracket never applies. Non-grantor irrevocable trusts (complex accumulation trusts, dynasty trusts, certain irrevocable trusts) are separate taxpayers that file Form 1041. Only non-grantor trusts benefit from the DI compressed-bracket strategy.

Can a trust distribute capital gains to beneficiaries at lower rates?

Rarely under the default rules. Under IRC § 643(a) and UPIA, capital gains are typically allocated to principal and excluded from DNI — meaning the trust can't deduct a distribution of those gains, and beneficiaries don't include them in income. Some modern trust documents give trustees discretionary power to include gains in DNI, enabling distribution to beneficiaries at their individual rates. This is a trust-document-and-state-law question for the trust attorney — it's worth resolving before deploying DI, because distribution flexibility and DI are complementary, not competing, strategies.

Which platforms are best for trust accounts?

Parametric and Aperio are the gold standard for complex trusts with related family accounts — they offer true cross-account wash-sale monitoring across the grantor's personal, IRA, and trust accounts. Vanguard Personalized Indexing is a cost-effective advisor option for trusts with simpler structures. Schwab Personalized Indexing works for smaller trusts without complex family account relationships. Self-directed platforms like Wealthfront and Frec have limited trust account support and no cross-account wash-sale visibility — use advisor-managed platforms for any non-trivial trust DI deployment.
