Goldman Sachs Direct Indexing: TACS Platform Review (2026)

Goldman Sachs Asset Management has been running direct indexing for over 25 years. Its Tax-Advantaged Core Strategies (TACS) platform now manages approximately $191 billion in direct indexing assets — one of the largest pools of direct indexing capital in the industry, rivaled only by Parametric. The platform requires a $250,000 minimum, charges approximately 0.20% as a platform/style-manager fee, and is available through RIA advisers and major wirehouse UMA programs including Merrill Lynch and Morgan Stanley. A new ETF Look-Through capability launched in May 2025 is now available to the RIA channel — a meaningful differentiator that lets GSAM manage a client's existing ETF positions alongside the direct indexing account as a single unified portfolio. Here's what the platform delivers, where it stands out, and when it is the right choice.

How Goldman Sachs TACS works

Tax-Advantaged Core Strategies (TACS) is Goldman Sachs Asset Management's flagship direct indexing platform. The structure is an individually managed separately managed account (SMA): rather than buying an ETF or mutual fund, the client directly owns the 200–500 individual stocks that replicate the chosen benchmark. Direct ownership is what enables single-stock tax-loss harvesting — selling a position that has declined to realize a capital loss while reinvesting in a comparable security to maintain index exposure during the IRC §1091 30-day wash-sale window.¹

GSAM runs a quantitative optimization algorithm across the portfolio daily. The algorithm seeks to maximize tax-loss harvesting opportunities while keeping the portfolio sector-neutral, industry-neutral, and style-factor-neutral relative to the benchmark. This means the direct indexing account tracks index risk and return — not perfectly, because individual stocks introduce idiosyncratic noise — but within defined tracking error constraints. Each harvested loss is a realized capital loss that the investor can use to offset gains from RSU sales, K-1 partnership distributions, property sales, or Roth conversion income (within the §1211(b) $3,000/year limit for ordinary income).

Minimum, fee structure, and total cost

The meaningful cost comparison is the incremental fee over a low-cost ETF. Using a broad-market ETF at ~0.03% as baseline, the incremental GSAM TACS fee is approximately 0.17%/year. At a 1.0% annual harvest rate and the 2026 combined federal LTCG+NIIT rate of 23.8%, the gross annual tax alpha is roughly $2,380 per $1M invested — well above the $1,700 incremental fee premium. In high-tax states the margin widens substantially:

Uses 2026 combined LTCG+NIIT rate of 23.8% (federal only; 20% LTCG + 3.8% NIIT) per IRS Rev. Proc. 2025-32. 20% LTCG applies above $613,700 MFJ / $545,500 single; NIIT applies above $250,000 MFJ / $200,000 single — not inflation adjusted. Assumes 1.0%/year harvest rate. Fee premium uses 0.20% GSAM − 0.03% comparable ETF = 0.17%. State taxes significantly increase the benefit in CA (37.1%), NY/NYC (37.3%+), NJ (34.55%), OR (~33.7%), CT (30.79%), MA (28.8%). Estimates only — actual harvest rates vary with market conditions and may be higher in volatile markets.²

Available strategies

GSAM offers a range of predefined benchmark strategies rather than a single-benchmark approach. Available strategies include S&P 500, Russell 3000 (broad US market), US All Cap, and an ESG Diversified US Large Cap option for clients with responsible investing requirements. Internationally, TACS offers an MSCI EAFE ADR strategy — one of the few advisor-tier direct indexing platforms with a dedicated developed-market international option.³

• TACS S&P 500 — tracks the S&P 500 with direct stock ownership and daily TLH optimization
• TACS Russell 3000 — broad US market exposure across large, mid, and small cap; wider stock universe enables more TLH opportunities
• TACS US All Cap — full US market spectrum; available on Morgan Stanley UMA programs
• TACS ESG Diversified US Large Cap — incorporates ESG screens and factor tilts while maintaining TLH harvesting
• TACS MSCI EAFE ADR — developed-market international direct indexing; useful for investors who want TLH capability on their international equity allocation, not just domestic

The strategy menu is an intermediate tier of flexibility — broader than single-benchmark platforms like Vanguard VPI but not as flexible as Parametric or Aperio's fully custom benchmark construction. For most investors, the predefined strategies cover the common use cases without requiring a bespoke mandate.

The ETF Look-Through feature

The most differentiated feature Goldman Sachs TACS offers as of 2026 is ETF Look-Through, launched in May 2025 for the RIA channel. Most direct indexing platforms manage the direct indexing account in isolation — they see only the individual stocks inside the SMA, not what the client holds in ETFs at other custodians or in a brokerage account. This creates wash-sale blind spots: if a client owns SPY in their brokerage account and the TACS algorithm sells an S&P 500 stock, a subsequent rebalancing purchase in SPY can inadvertently trigger a wash-sale violation.⁴

ETF Look-Through addresses this by allowing GSAM to combine eligible ETF positions the client holds and incorporate their underlying constituents into a single unified advisory account. GSAM manages the ETF alongside the direct indexing stocks — trimming or selling ETF exposure based on risk and tax consequences, rebalancing the portfolio to reduce concentration from ETF positions, and monitoring wash-sale overlap across the combined holding. This serves two distinct use cases:

• ETF-to-DI transition: A client holding $1M in VOO (Vanguard S&P 500 ETF) with large embedded gains cannot easily sell the ETF without a substantial tax bill. With ETF Look-Through, GSAM can hold the VOO position, manage it as part of the unified account, build a loss bank through the individual stock positions, and systematically reduce ETF exposure over time as losses accumulate — without forcing a taxable liquidation event at the outset. For the ETF transition problem this site covers in the transition guide, this is a meaningful practical advance.
• Ongoing combined management: Investors who want some ETF exposure alongside a DI account (for example, international ETFs outside the EAFE ADR strategy) can have GSAM monitor the full picture for wash-sale compliance, rather than the adviser manually tracking cross-position conflicts.

Wirehouse availability: Merrill Lynch and Morgan Stanley

Goldman Sachs TACS is available within unified managed account (UMA) programs at major wirehouses, including Merrill Lynch and Morgan Stanley. This matters for two reasons.³

First, many Merrill Lynch and Morgan Stanley clients hold TACS accounts through their wirehouse adviser without working with an independent RIA. If you are already a Merrill Lynch or Morgan Stanley client and your adviser proposes TACS, this is the same Goldman Sachs institutional direct indexing platform, not a retail product — the same quantitative infrastructure, the same benchmark strategies, the same daily harvesting. What varies is the adviser's fee structure and how well they coordinate the DI account with your broader tax plan.

Second, the wirehouse availability creates an important cost comparison. Wirehouse all-in fees for a $1M TACS account typically run 1.00–1.35% (0.20% GSAM platform fee + wirehouse advisory fee). Fee-only RIAs typically charge 0.50–0.85% advisory fees, producing an all-in cost of 0.70–1.05% at the same account size — a gap of roughly 0.30%/year at $1M that compounds significantly over time. Accessing TACS through a fee-only RIA rather than a wirehouse adviser is not always possible (depends on your adviser's custodial setup), but when it is, the cost differential is worth examining.

Goldman Sachs TACS vs. leading advisor-tier platforms

ESG and customization

Goldman Sachs TACS supports customization at several levels: predefined ESG strategies (the ESG Diversified US Large Cap strategy incorporates ESG screens into the benchmark construction), security exclusions (specific companies or industries), and concentrated-position screens that exclude the employer's stock from the portfolio to prevent adding to an already-large position.

TACS's ESG depth sits at an intermediate tier — more capable than retail self-serve platforms (Schwab SPI, Wealthfront) but not at the revenue-exposure and controversy-level granularity that Aperio/BlackRock provides for UHNW mandates. For most investors whose ESG requirements are "exclude tobacco and firearms" or "tilt toward low-carbon," the GSAM ESG Diversified strategy covers the need. For institutional ESG mandates — board-level carbon footprint reporting, engagement-grade exclusions, or long/short 130/30 ESG strategies — Aperio is the more appropriate platform.

Wash-sale compliance and cross-account coordination

Within the TACS account itself, GSAM's quantitative algorithm handles wash-sale compliance automatically: it harvests losses by selling declining positions and reinvesting in comparable-but-not-substantially-identical securities to maintain index exposure during the 30-day IRC §1091 window. The ETF Look-Through feature extends this compliance to eligible ETF positions held in the same advisory account.¹

Cross-account wash-sale management — preventing disallowed losses when the same security is purchased in an IRA, 401(k), or non-enrolled brokerage account within the wash-sale window — remains the adviser's responsibility, as it does on all direct indexing platforms. The practical difference: GSAM's ETF Look-Through reduces one common cross-account conflict (ETF holdings and DI stocks in the same platform) that advisers currently track manually. For investors with RSU vesting, payroll-deducted 401(k) contributions, or IRA holdings in the same securities as the TACS portfolio, careful adviser coordination of harvest timing is still required. See the wash-sale guide for the full mechanics.

State tax rate impact by state

Goldman Sachs TACS delivers the most value in high combined LTCG rate states. The following estimates annual net benefit at $1M in taxable assets (1.0% harvest rate, 0.17% incremental fee premium over ETF):

1.0%/year harvest rate; 0.17% fee premium (0.20% GSAM − 0.03% comparable ETF). State rates from respective state guides verified against current tax law. 2026 federal LTCG thresholds per IRS Rev. Proc. 2025-32. Harvest rates vary with market conditions — volatile years can generate 2–3× the steady-state harvest rate, amplifying the benefit significantly. These estimates are incremental benefit from the DI platform fee only; the adviser's separate fee is additional.²

Who Goldman Sachs TACS is best suited for

Best fit:

• Investors with $500K+ in taxable accounts already working with an adviser who has GSAM TACS integration — particularly RIAs using GSAM strategies or Merrill Lynch / Morgan Stanley clients whose adviser proposes TACS through the UMA program
• Investors with existing ETF portfolios and large embedded gains who need an ETF-to-DI transition solution — ETF Look-Through is the most advanced available mechanism for this problem at any advisor-tier platform as of 2026
• High-income earners in the top federal bracket ($613,700+ MFJ) facing the 23.8% combined federal LTCG+NIIT rate, amplified in California (37.1%), New York/NYC (37.3%+), New Jersey (34.55%), Connecticut (30.79%), or Maryland (35.5%)²
• Investors who want international direct indexing as well as domestic — the MSCI EAFE ADR strategy gives TACS clients a developed-market TLH account, not just a US equity DI sleeve
• Executives with RSUs or NQSOs who need an employer-stock exclusion screen alongside systematic TLH — a combined employer-stock exclusion and daily harvest algorithm manages the wash-sale and concentration risks in one account

Consider alternatives when:

• You need a fully custom benchmark (any index, any factor combination) — Parametric or Aperio offers deeper custom construction than TACS's predefined strategy menu
• You want self-directed access without an adviser — no advisor-tier platform has a retail version; use Schwab Personalized Indexing ($100K, 0.40%) or Wealthfront ($100K, 0.25%) for self-serve
• You have $1M+ and institutional-grade ESG requirements — Aperio/BlackRock offers deeper revenue-based and controversy-level ESG screening than GSAM
• Your account is below $250K — Frec ($20K, 0.09%) or Fidelity FidFolios ($5K, 0.40%) are accessible entry points; Schwab SPI and Wealthfront are the $100K tier
• Your adviser uses a different SMA platform exclusively — switching platforms creates friction and potential transition costs; check whether GSAM TACS integration is available through your current adviser's custodian before assuming access

Frequently asked questions

What is Goldman Sachs direct indexing?

Goldman Sachs direct indexing is the Tax-Advantaged Core Strategies (TACS) platform managed by Goldman Sachs Asset Management. Available through registered investment advisers and wirehouse UMA programs (Merrill Lynch, Morgan Stanley), TACS creates a separately managed account of individual stocks replicating a chosen index — S&P 500, Russell 3000, US All Cap, ESG Diversified US Large Cap, or MSCI EAFE ADR — while running daily automated tax-loss harvesting. Minimum is $250,000; platform fee is approximately 0.20%. The platform manages approximately $191 billion in direct indexing assets, built over a 25+ year operating history. Adviser-only — no retail self-service version.

What is Goldman Sachs TACS?

TACS stands for Tax-Advantaged Core Strategies — Goldman Sachs Asset Management's direct indexing separately managed account product. The platform uses a quantitative optimization algorithm that harvests tax losses daily while keeping the portfolio sector-neutral, industry-neutral, and factor-neutral relative to the chosen benchmark. Strategies include S&P 500, Russell 3000, US All Cap, ESG Diversified US Large Cap, and MSCI EAFE ADR (international). Available through RIA advisers and wirehouse UMA programs; $250,000 minimum; ~0.20% platform fee. Source: Goldman Sachs Asset Management, am.gs.com/en-us/advisors/products/direct-indexing.

What is the Goldman Sachs ETF Look-Through feature?

ETF Look-Through is a GSAM TACS feature launched in May 2025, initially for the RIA channel. It allows Goldman Sachs to "look through" to the individual holdings underlying an eligible ETF the client holds in the same advisory account, managing the ETF and direct indexing stocks as a unified portfolio. GSAM monitors wash-sale overlap between the ETF and individual stock positions, and can rebalance the account to reduce concentration from ETF underlying holdings. This makes TACS particularly powerful for ETF-to-DI transitions: rather than forcing a large taxable gain by selling the ETF first, GSAM can build a DI loss bank while holding the ETF and systematically reduce the ETF position over time in a tax-efficient way.

Is Goldman Sachs direct indexing adviser-only?

Yes. Goldman Sachs TACS is available only through registered investment advisers with access to the GSAM direct indexing platform, or through wirehouse clients at Merrill Lynch or Morgan Stanley whose adviser uses TACS strategies within the UMA program. There is no retail self-service version of TACS. Investors who want self-directed direct indexing without an adviser should consider Schwab Personalized Indexing ($100K minimum, 0.40%) or Wealthfront Direct Indexing ($100K, 0.25%).

How does Goldman Sachs TACS compare to Parametric?

Both are advisor-only platforms with approximately $250,000 minimums and 0.20% platform fees. Parametric (Morgan Stanley subsidiary, founded 1992, ~$420B+ DI AUM) is the largest direct indexer by AUM and offers the deepest custom benchmark construction. Goldman Sachs TACS (~$191B DI AUM, 25+ year history) differentiates via its ETF Look-Through feature (unique as of 2026), international DI strategy (MSCI EAFE ADR), and broad wirehouse UMA availability at Merrill Lynch and Morgan Stanley. TACS uses predefined strategy options rather than fully custom benchmarks — for investors who need a custom benchmark, Parametric is the better fit; for investors needing ETF Look-Through or with access through a Merrill Lynch or Morgan Stanley adviser, TACS is a strong alternative.
