UHNW Portfolio Allocation: Building a $30M–$150M Portfolio

A framework for structuring a $30M–$150M portfolio across public equity, fixed income, alternatives, and real assets — covering liquidity tiers, tax-aware sleeve design, and the Investment Policy Statement. Not investment advice — your liquidity needs, tax situation, and time horizon determine the right allocation.

Why portfolio construction changes at $30M+

Three things shift meaningfully once net worth reaches UHNW scale:

1. Access to private markets widens. Minimum LP commitments to institutional-quality private equity and hedge funds ($1–5M per fund) become feasible. The illiquidity premium that has historically added 3–5% annually over public market equivalents is now available to you — but only if you can sustain the lockup without liquidity stress.
2. Tax drag on the portfolio becomes the dominant variable. At the 37% ordinary income rate and 23.8% combined LTCG+NIIT rate (2026), the difference between tax-aware and tax-oblivious portfolio construction can exceed 1% per year in after-tax return — more than many advisor fees. Asset location, tax-loss harvesting, and security selection all matter.
3. Complexity requires coordination, not just optimization. A $50M portfolio spanning direct-indexed equities, PE fund commitments, private real estate, a concentrated employer stock position, and multiple trust structures cannot be managed as independent accounts. Integration across sleeves is what UHNW specialists provide that generalists don't.

The liquidity tiering framework

Before building any allocation, map your capital into three tiers based on when you might actually need it. Deploying illiquid capital you need in three years creates forced-liquidation risk:

Sleeve 1: Public equity — direct indexing vs. ETFs

At $30M+, the question in public equity is almost never "ETFs vs. active mutual funds" — it's "direct indexing vs. ETFs." The answer turns on tax situation and portfolio complexity:

• ETFs work well for short-duration tax-exempt accounts (Roth IRA, HSA) and for asset classes where individual security selection adds little (small-cap international, emerging markets, real estate). Low cost and low maintenance.
• Direct indexing (separately managed accounts holding individual securities tracking an index) generates ongoing tax-loss harvesting that can add 0.5–1.5% in after-tax return annually at UHNW scale, with greater benefit in higher-volatility years. Minimums start at $250K–$500K per account (Parametric, Aperio/BlackRock) — practical at UHNW scale but not below $500K of taxable equity.¹

At the 23.8% combined LTCG+NIIT rate (2026), harvested losses in a direct-indexed account are worth roughly 24 cents per dollar if used to offset capital gains — or carried forward indefinitely if not. The harvesting benefit compounds over time and integrates naturally with estate planning (§1014 step-up eliminates embedded losses at death, so harvested losses used during lifetime are "free" from an estate perspective).

For concentrated employer stock, direct indexing also allows gradual diversification — adding offsetting short positions in correlated names, donating high-basis lots to a DAF, or systematic sale during low-income years.

Sleeve 2: Fixed income — munis at the 37% bracket

UHNW investors in the top federal bracket and in high-tax states often find that tax-exempt municipal bonds offer better after-tax yield than taxable alternatives of equivalent credit risk. The comparison is straightforward:

Tax-equivalent yield (TEY) formula:
TEY = muni yield ÷ (1 − combined marginal rate)

Example: If you're a California resident in the 37% federal bracket (+ 13.3% CA state rate), an in-state California muni yielding 3.8% has a federal+state TEY of approximately 3.8% ÷ (1 − 0.37 − 0.133) = 8.1% TEY.² A taxable bond would need to yield 8.1% with equivalent credit quality to match the after-tax return — a high bar in most rate environments.

Key muni mechanics at UHNW scale:

• AMT preference items: Private activity bonds (PABs) can trigger AMT preference income. Post-OBBBA (2025), the AMT exemption phaseout begins at $1M MFJ at a 50% rate — meaning high-earning UHNW taxpayers may still face AMT exposure. Avoid PABs if AMT is a risk; stick to general obligation or essential-service revenue bonds.
• NIIT exemption: Muni interest is excluded from the 3.8% NIIT base, which further improves the after-tax comparison against taxable bonds for UHNW investors above the $250K MFJ threshold.
• Estate tax note: Munis held at death receive a §1014 stepped-up basis (for income tax purposes the step-up is moot since munis are already tax-exempt), but they are included in the gross estate. For estate-tax planning purposes, this favors PPLI or irrevocable trust structures over munis for the longest-duration portion of the portfolio.

Sleeve 3: Alternatives — sizing the illiquidity premium

According to the UBS Global Family Office Report 2025, U.S. family offices allocate 54% of their portfolios to alternatives on average — 27% private equity, 18% real estate, and 3% private debt.³ That allocation reflects offices with dedicated investment staff and $100M+ in assets; for $30–100M portfolios working with a fee-only advisor, a 20–35% alternative allocation is more commonly appropriate.

The key constraints on alternatives sizing are:

• Unfunded commitments: PE and VC funds issue capital calls over 3–5 years; you must maintain 1.5× total uncalled commitments in liquid assets within 30 days. Overcommitting to alternatives creates capital-call pressure that can force selling public positions at inopportune times.
• Vintage-year diversification: Committing $10M to one PE fund in a single vintage concentrates market-entry risk. Spreading $10M across 2–3 funds per year over 3–4 years is standard practice for building a private markets portfolio with managed J-curve exposure.
• GP access: The median-vs.-top-quartile spread in PE net IRR consistently runs 5–10 percentage points. Getting into the wrong fund at the right allocation underperforms a public-market strategy. A UHNW specialist with existing GP relationships is often the only practical access point for allocation-sized commitments to established managers.

Sleeve 4: Real assets and inflation hedging

Real assets — private real estate, infrastructure, farmland, timber, and commodities — serve as inflation hedges and portfolio diversifiers with low correlation to public equity. At UHNW scale, the access options expand beyond REITs:

• Private real estate: Direct ownership, private equity real estate funds (PERE), or DST (Delaware Statutory Trust) structures that qualify for 1031 exchange treatment. Direct ownership provides depreciation deductions; PERE funds provide diversification with less management burden. See the 1031 Exchange guide for tax deferral mechanics.
• Infrastructure: Toll roads, pipelines, utilities, data centers. Long-duration cash flows, often inflation-indexed. Accessed through PE-style infrastructure funds with 10–15 year lockups. Historically strong performance in high-inflation regimes.
• Farmland and timber: Low-volatility real assets with biological growth components. Noncorrelated to equity markets. Available through direct ownership or REITs — direct ownership provides more tax-planning flexibility (depletion deductions on timber, depreciation on structures).

The Investment Policy Statement (IPS)

An IPS is the governing document that formalizes your portfolio objectives, constraints, and asset allocation targets. At UHNW scale, it's essential because it:

• Documents the rationale for each sleeve allocation — so decisions made in a calm market aren't second-guessed in a volatile one
• Defines rebalancing triggers (e.g., "rebalance when any sleeve deviates more than 5% from target") so portfolio drift is managed systematically, not reactively
• Specifies liquidity requirements and the capital call reserve policy
• Coordinates with trust documents — directed trustee structures often require an IPS as an exhibit to define the investment standard
• Sets tax-management priorities: which accounts to use for income-generating assets vs. growth assets (asset location), whether to harvest losses annually or opportunistically, and the stance on tax-lot management

A well-drafted IPS for a $50M UHNW family is typically 10–20 pages and is updated annually or after a material life event (new business exit, large inheritance, divorce, birth of grandchildren). Your fee-only advisor drafts it; the family and relevant trustees approve it.

How a fee-only UHNW specialist builds and manages this

The coordinator role is where UHNW advisors earn their fee. Specific functions that require cross-account visibility:

• Balance-sheet mapping: Inventorying all assets — in trusts, in the business, in family members' accounts, in partnership interests — before sizing any sleeve
• Tax-lot management: Coordinating lots across direct-indexed accounts, trusts, and brokerage accounts so TLH doesn't create wash-sale violations through related accounts
• Capital call liquidity management: Monitoring unfunded PE commitments and maintaining the required T2 buffer; signaling when it's safe to commit new capital
• IPS drafting and annual review: Writing and updating the governing document; coordinating with estate attorneys when trust or family governance changes require IPS revision
• GP sourcing: Providing access to established private equity GPs who are not taking cold outreach from new LPs
• Tax filing coordination: Briefing your CPA on K-1 timing, loss harvesting realized in the year, charitable transfers, and PPLI adjustments so the tax return reflects the portfolio strategy
