Can You Retire with $20 Million?

What $20 million supports: the withdrawal rate math

At $20M, essentially every spending scenario is covered at very conservative withdrawal rates:

Add Social Security — a couple with maximum benefits both claiming at age 70 receives $124,344 per year combined ($5,181 × 2 × 12) in 2026¹ — and the effective portfolio draw drops well below 2%. At those draw rates, the portfolio compounds in retirement. The "can I retire?" question is settled. What $20 million demands is disciplined estate and tax architecture before portfolio growth compounds your exposure.

The four planning priorities at $20 million

1. Federal estate tax: singles are exposed today; couples need a timeline

The OBBBA (One Big Beautiful Bill Act, July 2025) made the federal estate tax exemption permanent at $15 million per person — $30 million for married couples using portability.⁴

• Single individuals at $20M are $5 million above the exemption: $5M × 40% = $2 million in federal estate tax right now, plus 16–40% in applicable state estate taxes on the full taxable amount. This is not a future problem — it is the current state. Every year of growth at 7% adds another $1.4M+ to the taxable estate. The window for GRATs, SLATs, and annual gifting to move appreciation out of the estate is now, not later.
• Married couples at $20M have $10M in unused exemption today (combined $30M - $20M). But at 7% returns, the portfolio reaches $30M in about 6 years, and $40M in 12 years. The surviving spouse, who inherits the entire estate, has only a single $15M exemption without active portability planning. A $40M estate in year 12 — entirely plausible — could face $10M+ in federal estate tax if nothing is structured ahead of time.

Core estate tools at $20M:

• Annual gifting: $19,000/donor/recipient in 2026 ($38,000 for married couples). A couple gifting to 3 children transfers $114,000/year tax-free — meaningful but not sufficient alone at $20M scale.⁴
• GRATs (Grantor Retained Annuity Trusts): Move appreciation above the §7520 hurdle rate (5.20% in August 2026) to heirs tax-free. A $5M GRAT in growth assets returning 10% transfers ~$920,000 to heirs after 2 years at zero gift tax cost. Rolling 2-year GRATs are the primary tool for moving appreciation efficiently at this scale.
• SLATs (Spousal Lifetime Access Trusts): One spouse funds a trust benefiting the other, removing assets from both estates while retaining indirect access. A $5M SLAT today removes $5M plus all future appreciation. Requires careful drafting to avoid the reciprocal trust doctrine.
• Dynasty trust: At $20M, funding a dynasty trust with $10–15M while the remaining estate is still below or near the exemption protects that capital from estate taxes for multiple generations. The GST (generation-skipping transfer) exemption of $15M per person in 2026 aligns with the estate exemption under OBBBA.
• 529 superfunding: $95,000 per donor ($190,000 for couples) using the 5-year election per IRC §529(c)(2)(B) removes funds from the estate and grows tax-free.⁴

See our full trust strategies guide (GRAT, SLAT, QPRT mechanics and calculator) and estate planning overview for $2M–$20M.

2. State estate taxes: $2.5M–$4M in additional exposure

State estate taxes are entirely independent of the federal OBBBA changes and have no portability between spouses. For residents of high-estate-tax states, a $20M estate faces substantial additional tax:

None of these states conformed to the OBBBA federal exemption increase. None allow portability between spouses. For an Oregon or Washington resident with a $20M estate, state estate taxes alone represent $2.8M–$3.8M in additional exposure on top of any federal liability. Domicile change, annual gifting, and trust structures are the primary tools. See our state tax relocation planning guide.

3. IRMAA: permanently maxed, unavoidable without deliberate Roth conversion

A $20M portfolio generating a 4% return produces $800,000 in annual investment income before Social Security or required minimum distributions. At this income level, MAGI almost certainly exceeds $750,000 for a married couple — the top IRMAA tier in 2026. The annual Medicare cost:²

• Part B top tier: $689.90/month × 2 persons × 12 months = $16,558/year
• Part D surcharge top tier: $91.00/month × 2 × 12 = $2,184/year
• Total: ~$18,742/year in Medicare premiums vs. ~$4,870/year at base

That's a $13,872 annual surcharge above base. Over two spouses' 20-year retirements, the cumulative cost is ~$280,000 above base — irreducible without meaningful reduction in MAGI. The only lever that moves IRMAA tiers substantially is aggressive Roth conversion before RMDs begin: converting $300,000–$500,000 per year in the window between retirement and age 73 or 75 reduces the traditional IRA balance that generates forced ordinary income, potentially dropping the couple from top-tier to Tier 2 or Tier 3 IRMAA. See our IRMAA planning guide and 2026 bracket table.

4. Required minimum distributions and the advisor cost problem

Under SECURE 2.0, RMDs begin at age 73 for those born 1951–1959 and age 75 for those born 1960 or later.³ At $20M with significant traditional IRA/401(k) exposure, mandatory distributions are substantial:

All of those distributions are ordinary income — taxed at 37% federally above $751,600 MFJ in 2026, plus state income tax. Roth conversions in the years between retirement and RMD age are the primary tool: converting $300,000–$500,000 per year at 32–35% marginal rates reduces the forced RMD at 37% and reduces IRMAA tier simultaneously. See our Roth conversion strategy guide and RMD planning guide.

Advisor cost at $20M: A 1% AUM fee on $20 million is $200,000 per year — every year, whether markets go up or down. Over 25 years at a 7% nominal return, the compounding cost of that fee exceeds $9 million in foregone portfolio value. A flat retainer of $50,000–$80,000 per year covers comprehensive planning for a $20M portfolio at a fraction of the AUM cost. At this wealth level, the fee structure conversation is one of the highest-leverage planning decisions you make.

Planning priorities at $20 million

Estate planning: the time-sensitive component

At $20M, estate planning is not a future item — it is the most pressing financial planning decision you have right now. For singles, $5M is already above the exemption. For couples, the combined $30M exemption buffer erodes at ~$1.4M/year at 7% portfolio growth, and the surviving spouse's single $15M exemption creates a long-term exposure that begins the day your spouse passes. The tools that work best are implemented early, because they transfer future appreciation — not current value:

• Rolling 2-year GRATs: Each GRAT "succeeds" if the assets return more than the §7520 hurdle rate (5.20% in August 2026). A 2-year GRAT funded with $5M in an equity portfolio returning 10% transfers ~$920,000 to heirs tax-free. Rolling the strategy annually across multiple trusts creates a systematic transfer machine.
• Dynasty trust: At $20M, funding a dynasty trust with $10–15M uses the GST exemption ($15M per person in 2026) to shelter that capital from estate tax across all future generations. The capital and all its future growth are permanently outside the taxable estate.
• SLAT strategy for couples: Each spouse funds a trust benefiting the other, using $10–15M of combined assets. Removes $10–15M plus all appreciation from both estates, while each spouse retains indirect access through the beneficiary relationship. Reciprocal trust doctrine risk requires non-identical trust terms.
• Annual and superfunding gifts: $38,000/year for married couples to each recipient (direct), plus $190,000 per recipient via 529 superfunding. With 3 children and 6 grandchildren, a couple can shift $760,000+/year from the estate systematically.

See our estate planning guide, GRAT, SLAT & QPRT guide with calculator, and Family Limited Partnership guide.

Investment structure at $20M

At $20M you have full Qualified Purchaser status ($5M in investments per §2(a)(51))⁵ and access to the full institutional alternatives universe:

• Direct indexing at scale: At $12M+ in taxable accounts, running 8–12 direct indexing sleeves generates $96,000–$192,000/year in systematic tax-loss harvesting. This is materially different from what a fund-based portfolio can produce — it's essentially a tax alpha engine running continuously on your largest asset.
• Institutional alternatives: $2M–$4M in private equity (vintage-diversified across 4–5 funds, with co-investment rights available at this scale), $1M–$2M in private credit, and $500K–$1M in real assets is a reasonable alternatives sleeve — meaningful diversification without J-curve overexposure.
• Advisor cost structure: At $200,000/year at 1% AUM, the advisor fee is itself a planning variable. A flat retainer of $50,000–$80,000 covers the same comprehensive planning work and saves $120,000–$150,000 per year in cash — $3–4M+ when invested over 25 years. At $20M, selecting an advisor based on fee structure alone recovers more value than most investment decisions.

Advisor landscape at $20M

At $20M you will receive attention from:

• Wirehouse private banking: Merrill Lynch Private Banking, Morgan Stanley Wealth Management, UBS — typically $5M–$10M minimums, 0.75–1.25% AUM (= $150,000–$250,000/year at $20M), operating under Reg BI (best interest, not strict fiduciary standard).
• Bank private wealth: JPMorgan Private Bank ($10M+), Goldman Sachs Private Wealth ($25M minimum) — high service levels, proprietary products, similar AUM fee model.
• Multi-family offices (MFOs): Accept clients at $15M–$25M+; fees range from 0.5–1.0% or flat; services include tax, estate, investment, and family governance. A good fit if your needs span multiple family members and complex entities.
• Single-family office (SFO): Typically requires $50M+ to justify the cost. At $20M, SFO economics don't work — but a strong MFO or fee-only RIA provides equivalent planning without the overhead.
• Fee-only RIAs: For $2M–$20M, independent fee-only advisors — fiduciaries charging flat retainers of $40,000–$80,000/year — consistently provide better alignment and dramatically lower cost. At $20M, the difference between 1% AUM ($200K/yr) and a $70K flat retainer is $130,000/year in savings, or $5–6M over a 25-year compounding horizon.
