How to Invest $8 Million

What's different at $8 million vs $7 million

The jump from $7M to $8M isn't just another $1M. Several structural realities become more pressing at this level — and the cost of ignoring them grows accordingly:

1. State estate taxes represent $500K–$850K+ in high-tax states. The federal estate and gift tax exemption is permanently $15 million per person under the OBBBA.¹ But twelve states and DC levy their own estate taxes with far lower exemptions. At $8M, residents of Oregon ($1M exemption), Massachusetts ($2M exemption with a cliff effect), Washington ($3M exemption), or Minnesota ($3M exemption) face state estate taxes of $490,000–$840,000+ on a single death — without planning. That's a problem that doesn't fix itself at federal law changes.

2. A 1% AUM fee costs $80,000 this year. On $8M, a 1% AUM fee is $80,000 annually. Over 25 years at 7% gross return, that fee drag reduces your ending portfolio by approximately $3.5 million compared to a flat-fee fiduciary advisor charging $12,000–$20,000/year. The break-even on switching is measured in months, not years.

3. A large traditional IRA forces IRMAA exposure unless converted now. A $4.5M traditional IRA today, growing at 5% annually, reaches approximately $8.1M at age 75. The first required minimum distribution (Uniform Lifetime Table divisor 27.4) is approximately $295,000.⁴ Combined with Social Security of $62,000/year ($5,181 × 12),⁵ total income reaches $357,000 — pushing a married couple into IRMAA Tier 3 ($12,000–$15,000/year in Medicare surcharges) without Roth conversion planning that starts now.

4. You're firmly in QP territory — focus shifts from access to deployment quality. The Qualified Purchaser threshold under Investment Company Act §2(a)(51)² is $5M in investments. At $8M total, virtually all households qualify. The planning question is no longer "can I get into this fund?" It's: which PE vintages are you already in, are you capturing co-investment opportunities, and how does illiquid exposure interact with the rest of the portfolio's liquidity structure?

5. Direct indexing harvesting alpha is $24,000–$48,000/year. With $3M–$4M in taxable accounts typical at $8M, you can run 4–5 independent direct-index sleeves simultaneously. Each sleeve harvests losses from a distinct set of individual securities. Net annual after-tax alpha over ETF alternatives runs 0.3%–0.6%/year — $24,000–$48,000 on an $8M portfolio, compounding for decades.

Asset allocation at $8 million

The meaningful shift from $7M: at $8M, your illiquid alternatives allocation is typically $1.6M–$2.4M across 3–4 PE vintages. Managing capital call timing, secondary-market liquidity on existing positions, and co-investment sizing alongside the liquid portfolio requires an advisor who actively works with GPs — not just one who places clients into fund vehicles.

State estate tax exposure at $8M

Federal estate planning is largely resolved at $8M — the permanent $15M OBBBA exemption covers a single person's estate with room to spare. State estate taxes are the real exposure for residents of these states:

Three planning moves significantly reduce or eliminate this exposure:

• Credit shelter (bypass) trust at the first death. For married couples in OR, MA, MN, or WA, leaving assets to a credit shelter trust at the first death preserves both spouses' state exemptions. Without this, everything passes to the surviving spouse, who then faces only one exemption on the full $8M. The difference: $500,000–$800,000 in avoidable state estate tax in the highest-tax states.
• Domicile change to a no-estate-tax state. Florida, Texas, Nevada, Washington state (now reduced to 20% max rate), and others have no state income tax. Oregon and Massachusetts residents with $8M portfolios regularly model the state estate tax cost vs. the disruption of a real domicile change. A well-documented FL or TX domicile eliminates $500,000–$840,000 in estate tax exposure permanently.
• Dynasty trust structures. A Nevada, South Dakota, or Delaware dynasty trust can hold assets across multiple generations, taking advantage of favorable trust laws — no state income tax on trust income, extended rule-against-perpetuities periods, strong asset protection statutes. At $8M, setup costs ($5,000–$15,000 in legal fees, plus ongoing trustee fees) represent less than 0.2% of the estate. See the trust strategies guide for GRAT mechanics that can shift appreciation above the §7520 rate to heirs entirely gift-tax-free.

The fee math at $8 million

A 1% AUM fee on $8M is $80,000 this year. That number grows with the portfolio. Over 25 years at a 7% gross return, here's what the fee structures look like:

The fee-only RIA model is the strongest fit for most $8M households. These advisors hold fiduciary duty under the Investment Advisers Act §206, charge a flat or hourly fee, and have no product commissions influencing their recommendations. See fee-only vs. 1% AUM: the math at $2M–$10M for a full breakdown including 20-year compounding charts.

Roth conversion planning at $8M

At $8M total wealth, a significant share is often in tax-deferred accounts. Without systematic conversion, the resulting RMD stream creates two compounding problems: avoidably high ordinary income in retirement and permanent IRMAA exposure in Medicare.

Consider a household with $4.5M in a traditional IRA today. At 5% annual growth over 12 years, the account reaches approximately $8.1M at age 75. The first required minimum distribution using the Uniform Lifetime Table divisor of 27.4 is approximately $295,000.⁴ Combined with Social Security income at the 2026 maximum of $62,000/year ($5,181 × 12),⁵ total ordinary income is $357,000. This places a married couple squarely in IRMAA Tier 3, adding $12,000–$15,000/year in Medicare surcharges on top of the ordinary income tax bill.

The Roth conversion window — typically ages 62–73 or 62–75, between full career income and RMD onset — is when conversions are cheapest. Converting $150,000–$250,000/year at 22–24% during this window is almost always better than the 32–37% rate that applies once RMDs begin. The IRMAA benefit compounds separately: every dollar of pre-tax balance eliminated now is one less dollar generating permanent Medicare surcharges in retirement. See the full Roth conversion strategy guide for the detailed mechanics and case studies at this wealth level.

Direct indexing at $8M

Direct indexing — owning the individual stocks that constitute an index rather than a fund — generates tax-loss harvesting opportunities at the individual security level throughout the year, not just during broad market declines. At $8M with $3M–$4M in taxable accounts, this is a core strategy that pays for itself many times over.

Key mechanics at this wealth level:

• 4–5 independent sleeves. Each sleeve (US large-cap, US small-cap, international developed, EM, and optionally a sector or factor tilt) harvests losses from a distinct set of 40–200 individual securities. Running sleeves independently means losses in one sleeve don't conflict with the wash-sale rules in another.
• $24,000–$48,000/year in annual after-tax alpha (0.3%–0.6% of an $8M portfolio) from incremental tax-loss harvesting, net of SMA management fees (typically 0.15%–0.35% of the direct-indexed portion). This alpha is highest in volatile, high-dispersion markets — when individual stocks fall while the index holds flat.
• Cross-account wash-sale planning. You can sell a stock in your taxable direct-index sleeve and immediately buy an ETF proxy in your IRA without triggering a wash sale — the rule doesn't apply across accounts unless you also own the same or substantially identical security in both. At $8M with multiple account types, this cross-account coordination adds incremental harvesting capacity.
• Embedded gain management at scale. After 3–5 years of direct indexing, your sleeve accumulates embedded gains in appreciated positions. At $8M, integrating a DAF for charitable giving and coordinating direct-index exits with estate planning (stepped-up basis at death) becomes part of the annual tax plan. See the tax-loss harvesting guide for the full integration with charitable and estate strategy.

Access options at $8M: Fidelity Separately Managed Accounts (SMA, $100K minimum per sleeve), Vanguard Personalized Indexing ($250K minimum), Parametric (available through many fee-only advisors), Aperio (now BlackRock). The advisor relationship matters here — some custodians offer direct indexing only through their proprietary SMA platform, which may not be the lowest-cost option.

Private equity and alternatives at $8M

At $8M, PE and private credit deployment is no longer about crossing thresholds — it's about running a mature alternatives portfolio with vintage diversification, disciplined sizing, and cost management. Three realities that apply specifically at this wealth level:

• Vintage diversification across 3–4 years is achievable. With $1.6M–$2.4M in alternatives (20–30% of a growth bucket), you can commit $400K–$600K per year across multiple GPs and vintage years. This smooths J-curve drag, reduces dependence on any single fund's outcome, and creates a rolling cash flow as older vintages begin returning capital while new commitments deploy.
• PE secondaries as a liquidity and vintage tool. Secondary-market buyers purchase existing LP interests from institutional sellers — often at discounts to NAV. At $8M, some secondaries funds have minimums of $500K–$1M. Buying into secondaries gives you exposure to mature (post-J-curve) PE vintages you missed and provides more immediate cash flow than a new primary commitment.
• Co-investment opportunities at established GP relationships. GPs often offer co-investment on specific portfolio company follow-on rounds to their most engaged LPs — at zero management fee and zero carry. At $8M with $1.5M–$2M already committed, you're in a position to capture co-investment flow on individual deals, which meaningfully improves net IRR across your PE allocation when selected carefully.

Common mistakes at $8 million

1. Staying with a 1% AUM advisor past the $5M mark. The AUM model made sense at lower asset levels when comprehensive planning wasn't available elsewhere. At $8M, the same or better planning is available from fee-only fiduciaries for $12,000–$20,000/year — 75–85% less in annual cost. Switching inertia is real; so is $80,000/year.
2. Assuming the OBBBA $15M exemption eliminates estate planning urgency. The federal exemption is $15M per person. But if you live in Oregon, Massachusetts, Washington, or Minnesota, your $8M estate has a six-figure state estate tax problem that requires action today — credit shelter trust drafting, domicile planning, or dynasty trust structures. None of these happen automatically.
3. Not starting Roth conversions in the window before RMDs. The window between career income and RMD onset is finite. With a large traditional IRA growing toward $8M+ by age 75, every year of inaction at 22–24% is a missed opportunity relative to the 32–37% rate that will apply once $295,000+ in annual distributions become mandatory.
4. Holding PE commitments without matching liquidity. PE capital calls are unpredictable in timing. At $8M with $1.6M–$2.4M in alternatives commitments, $150K–$300K is typically callable at any time. The 3–5% liquidity bucket isn't idle cash — it's the structure that prevents forced selling of appreciated positions at the wrong moment.
5. Running a single ETF in taxable instead of direct indexing. Many $8M households continue holding broad-market ETFs out of inertia. The after-tax opportunity cost is $24,000–$48,000/year in foregone systematic harvesting. The break-even on transitioning from an ETF to a direct-index sleeve is typically 3–5 years of harvesting alpha — after which the benefit compresses (as embedded gains build) but never disappears.
6. Missing the Massachusetts estate tax cliff. Unlike most states that tax only the amount above the exemption, Massachusetts taxes the entire estate from dollar one once the estate exceeds $2M. A $7.9M estate in MA incurs roughly the same tax as a $7.9M estate in Oregon. A $8.1M estate in MA incurs significantly more tax — the cliff creates a perverse incentive to plan precisely around the $2M threshold that most households aren't aware of.

Choosing an advisor for an $8M portfolio

The advisor model that works best for most $8M households:

• Fee-only fiduciary RIA charging a flat retainer or hourly rate. No commissions, no product sales, no AUM conflict. Fiduciary duty under the Investment Advisers Act §206 means they must act in your interest, not their own. At $8M, the fee savings alone ($60,000–$65,000/year vs. 1% AUM) pay for multiple years of flat-fee planning in the first year.
• CFP + CPA coordination. Tax planning at $8M requires year-round income coordination across brackets, IRMAA tiers, QCD limits, conversion windows, and state estate tax considerations. A CFP who partners with or employs a CPA eliminates the planning gaps that occur when tax and investment advice happen in separate silos.
• Active GP relationships for alternatives access. At $8M, co-investment opportunities matter. Not all fee-only RIAs have established GP relationships that generate co-investment flow. Ask specifically which PE funds they have relationships with, whether their clients receive co-investment access, and whether they actively monitor secondary-market pricing on existing fund positions.
• Estate and trust coordination. At $8M, credit shelter trust drafting, dynasty trust setup, and GRAT design require an estate attorney. The best advisors maintain referral networks of estate attorneys who understand the interaction between investment structure and estate planning.
