Warren Buffett famously observed that his secretary pays a higher effective tax rate than he does. The asymmetry is not really about wealth — it is about the form of compensation. Wages are taxed reliably. Stock appreciation, dividends, deferred compensation, partnership allocations, and unrealized growth often are not.
Per ProPublica's 2021 analysis of leaked IRS records, the 25 wealthiest Americans paid an aggregate effective federal income tax rate of approximately 3.4% on their wealth growth from 2014 to 2018. Buffett individually was at 0.10%; Bezos at ~1%; Bloomberg at ~1.3%. Bill Gates, who sold significant Microsoft over the period, was at ~18% — higher because he realized gains. The pattern is consistent: those who can choose when (and whether) to realize, do.
Thirteen mechanisms
Each route the current code permits — and the Accord instrument that closes it. Cross-links go to the dedicated subpage for the mechanism's detail rules.
- Buy-borrow-die
- How it works: Hold appreciated stock; borrow against it for liquidity; basis steps up at death erasing decades of unrealized gain.Accord closure: Basis step-up eliminated; death is a realization event. Mechanism →
- Carried interest
- How it works: PE/hedge-fund principals' compensation taxed as long-term capital gain (23.8%) instead of ordinary income.Accord closure: Taxed as ordinary income; flows into the rate ladder. Mechanism →
- Founder-equity hold
- How it works: Founders accumulate stock that appreciates while drawing nominal salary; only realize at chosen times.Accord closure: Capital-gains convergence above the $10M lifetime cap brings the rate to ordinary marginal. Mechanism →
- Charitable deduction stacking
- How it works: Donate appreciated stock — deduct full fair market value without realizing the gain.Accord closure: Charitable deduction cap reduced to $10K/year per individual.
- Foundation / DAF routing
- How it works: Move wealth to controlled tax-exempt entity; investment returns compound tax-free; donor retains influence.Accord closure: Institutional Investment Excise on tax-exempt portfolios + foundation-transfer parity. Mechanism →
- Family-controlled trusts
- How it works: Multi-generational wealth in dynasty trusts that compound outside ordinary tax for decades.Accord closure: Institutional Investment Excise (replaces the unenforceable 50-yr deemed-realization rule earlier proposed). Mechanism →
- Lifetime gifts and GRATs
- How it works: Move wealth before death using lifetime exemption + grantor-retained annuity trusts to avoid estate tax.Accord closure: Lifetime gift parity; cumulative tracking; gift-tax brackets converge with estate-tax brackets. Mechanism →
- Like-kind exchanges (1031)
- How it works: Real-estate gains defer indefinitely through serial exchanges; basis steps up at death.Accord closure: Cumulative deferral cap; large rolling exchanges realize the gain. Mechanism →
- Pass-through games (S-corp, LLC)
- How it works: S-corp shareholder-employee takes low salary and high distribution to suppress payroll tax; partnership special allocations rearrange book income.Accord closure: The new payroll tax follows the substance of the work; comprehensive base captures the active-participation share regardless of entity labels. Mechanism →
- Real-estate depreciation losses
- How it works: Paper losses from accelerated depreciation offset other income; NOLs carry forward indefinitely.Accord closure: Corporate book minimum addresses entity side. The Accord taxes at every point of capture; cumulative-deferral and entity-routing rules limit individual real-estate-professional shelters.
- Opportunity Zones
- How it works: Capital-gain deferral plus step-up for OZ-fund investors; designation criteria political rather than need-based.Accord closure: OZ investor-side preferences eliminated; place-based investment redirected through COMPASS-triggered measurable-outcome funding. Mechanism →
- Private Placement Life Insurance (PPLI) and similar investment-wrapped insurance
- How it works: Wrap an investment portfolio in a §7702 life-insurance shell so gains compound tax-free indefinitely; popular among UHNW filers via Bermuda and Cayman insurers. The 'insurance' component is a vestigial term-life wrapper; the substance is investment.Accord closure: Recharacterized to substance under the insurance-substance test. An insurance product is taxed as insurance only when (a) the covered event is genuinely uncertain, (b) the insured loss would be catastrophic, (c) premium structure is actuarial rather than investment-driven, and (d) death-benefit-to-cash-value ratio is meaningful (≥4×). PPLI fails (c) and (d); the underlying investment activity pays the estate tax prepayment, capital-gains convergence, and basis-step-up rules that apply to any investment.
- State residency arbitrage
- How it works: Move legal residence to FL/TX/NV/WY for state-tax purposes; federal obligations continue but state burden drops.Accord closure: Federal architecture is uniform; this is a state-level concern, not an Engine 1 closure.
Named cases
From public reporting — primarily ProPublica's 2021 IRS-records investigation, NYT's Trump tax investigation (2020), Forbes wealth tracking, and direct public statements. Effective rates are computed against wealth growth, not against accounting income (the latter is what makes these rates so low).
How the architecture closes PPLI and other investment-wrapped insurance
Insurance is a mechanism to broaden the risk pool for a low-probability catastrophic occurrence. Any "insurance" mechanism that fails this premise is a tax shift, not insurance. Private Placement Life Insurance is the canonical example: a UHNW filer wraps an investment portfolio in a §7702 life-insurance shell (typically through Bermuda or Cayman insurers) so the gains compound tax-free indefinitely and pass to heirs free of income tax. The "insurance" is a vestigial term-life wrapper; the substance is investment.
The architecture applies the substance-over-form principle that governs the rest of Engine 1. An insurance product is taxed as insurance only when it passes a four-part test:
- Genuine uncertainty. The covered event is genuinely uncertain in occurrence, OR is timing-uncertain catastrophic (life insurance death is the canonical timing-uncertain case).
- Catastrophic loss. The insured loss would be catastrophic to the insured's standard of living.
- Actuarial pricing. The premium structure reflects actuarial pricing of the risk pool, not the cash-value buildup.
- Substantive death benefit. The death-benefit-to-cash-value ratio is at or above a meaningful floor (proposed: ≥ 4×).
When the test fails, the structure is recharacterized as investment for tax purposes. The underlying portfolio pays the estate tax prepayment, capital-gains convergence, basis-step-up elimination, and every other rule that applies to ordinary investment activity.
What this protects. Term life with substantial death benefit (passes all four tests). Whole life with death benefit ≥ 4× cash value (passes). Single-premium immediate annuities used for genuine longevity-risk insurance (passes). The architecture preserves legitimate insurance — defined as risk-pool-broadening for low-probability catastrophic events.
What this closes. PPLI. Variable universal life with low death-benefit-to-cash-value ratio. Insurance-wrapped portfolios where the insurance component is vestigial. Any "insurance" product whose marginal sale-pitch is tax compounding rather than risk transfer.
