CASE STUDY: Estate of Matthew T. Mellon II v. IRS
By: Sid Peddinti, Esq.

How the IRS Is Using Estate-Tax Valuation Rules to Challenge Cryptocurrency Discounts
By Sid Peddinti, Esq.
1. BACKGROUND
Matthew Taylor Mellon II, heir to the Mellon banking fortune, died unexpectedly in April 2018.
At death, he held a massive position in the cryptocurrency XRP, with partial restrictions related to agreements with Ripple.
Key estate facts (per cited sources):
- Reported value (Form 706): approx. $151 million after applying valuation discounts.
- IRS adjustment: IRS claims FMV closer to $242 million (disallowing most discounts).
- Proposed deficiency: Estimated additional estate tax in the tens of millions.
(Source: TI-Trust briefing)
The dispute centers on whether the estate may apply marketability, volatility, and contractual restriction discounts to the cryptocurrency holdings.
2. LEGAL AND TAX ISSUES
- Whether XRP tokens held by the decedent qualify for valuation discounts under IRC §2031 and its regulations.
- Whether contractual sale restrictions, liquidity limitations, and crypto-market volatility justify a lower FMV than quoted exchange prices.
- Whether the IRS may disregard discounts because crypto is treated as a readily tradable asset for tax purposes.
3. APPLICABLE LAW AND CODES
A. IRC § 2031 — Definition of Gross Estate; Fair Market Value
“The value of the gross estate shall be determined by including the value at the time of death of all property…”
FMV defined under Treas. Reg. §20.2031-1(b):
– Price between a willing buyer and willing seller,
– Neither under compulsion,
– Both having reasonable knowledge of relevant facts.
B. Valuation Doctrines
1. Lack of Marketability (LOM) Discount
Permitted where the asset cannot be readily sold in the market.
2. Lack of Control (LOC) Discount
Permitted for minority business interests.
3. Blockage Discount
Treas. Reg. §20.2031-2(e) allows discounts when selling a large block would depress market price.
4. Contractual Restrictions
Case law allows valuation adjustments if legal or contractual limits prevent immediate sale.
C. IRS Position on Cryptocurrency
IRS Notice 2014-21:
- Crypto is treated as property, not currency.
- FMV is typically determined by market-quoted price.
This creates tension:
Crypto is “property,” but its market does not behave like traditional securities, especially when restricted.
4. ANALYSIS – IRAC [Legal] FRAMEWORK
Legal Issue
Did the estate correctly discount the value of XRP based on:
– Extreme volatility,
– Illiquidity due to contractual restrictions,
– Large position size (blockage),
– Difficulty of immediate access and transfer?
Applicable Rule
IRC §2031 requires FMV at death.
Regulations and cases permit discounts where appropriate.
Crypto raises unique questions about “marketability.”
Legal Analysis
A. Volatility
XRP demonstrated extreme price swings. High volatility normally supports a marketability discount.
B. Contractual Restrictions
According to trust analysis and reporting, Mellon’s holdings were subject to sale/transfer restrictions, including limitations on volume and rate of liquidation.
These restrictions reduce true FMV because the asset cannot be sold at quoted price.
C. Blockage Effect
Mellon held a massive position.
Selling it would signal to the market and depress price — classic blockage discount circumstances.
D. Digital Asset Access Issues
Reports indicate Mellon used multiple phone-based wallets and private decision-making, making access complex.
Difficulty of accessing or controlling crypto wallets is itself a marketability risk.
E. IRS Counter-Position
IRS argues that regardless of restrictions:
– XRP had a public exchange price,
– Crypto is readily tradable property,
– Restrictions were “personal to Mellon” and shouldn’t reduce FMV.
Conclusion
The case will establish whether crypto-based valuation discounts are legitimate and how §2031 applies to:
– Token volatility,
– Restricted tokens,
– Liquidity constraints,
– Blockage discounts.
A ruling will affect every wealthy crypto holder.
5. BENT LAW™ [Business, Estate, Nonprofit, and Tax™] ANALYSIS
B — Business
XRP’s value tied to Ripple’s ecosystem.
Large, restricted holdings function more like a business asset than a retail crypto purchase.
E — Estate
Estate liquidity crisis: high tax bill + illiquid crypto.
Lack of structured estate planning for digital assets is a central failure.
N — Nonprofit
Had Mellon pre-positioned crypto into:
– A private foundation,
– CRT,
– NIMCRUT,
– DAF,
large appreciation could have bypassed estate tax entirely.
T — Tax
IRS disallowed a ~$90 million discount.
Demonstrates IRS readiness to apply aggressive valuation standards to crypto.
6. SECONDARY BENT (Behavior, Entity, Numbers, Timing)
Behavior
Mellon self-managed large crypto positions without institutional safeguards.
Entity
Held personally – not via:
– LLC,
– Trust,
– Foundation,
– FLP.
This exposed value to full estate tax.
Numbers
$151M reported vs. $242M IRS.
Difference = ~$90M valuation gap.
Estate tax ≈ 40%.
Potential deficiency ≈ $30–40 million.
Timing
Death in April 2018 – a volatile XRP period.
FMV swings near death date heightened complexity.
7. WHY THIS CASE IS CRITICAL
This is the first high-profile estate tax battle over cryptocurrency valuation.
It will likely influence:
- Digital asset appraisal standards
- IRS audit approach
- Estate planning for crypto millionaires/billionaires
- Entity structuring practices
- Blockage discount applications to digital assets
- Treatment of restricted tokens
- Executor duties for digital keys
8. MAJOR TAX LESSONS
(1) IRC §2031
FMV of all property included in gross estate.
(2) Treasury Regulation §20.2031-1(b)
Defines FMV and governs appraisal standards.
(3) IRC §2001
Imposes estate tax on the taxable estate.
(4) Treas. Reg. §20.2031-2(e)
Allows blockage discounts.
(5) IRS Notice 2014-21
Clarifies taxation of cryptocurrency as “property.”
(6) Case Law Supporting Discounts
Even though this case is ongoing, courts historically allow discounts when:
– Asset is restricted
– Large block depresses price
– Marketability limited
– Hypothetical buyer cannot instantly liquidate
These doctrines will be tested against digital assets for the first time.
9. PRACTICAL PLANNING IMPLICATIONS
Crypto requires:
– Entity ownership (LLC, FLP)
– Trust planning (IDGT, dynasty trust)
– Charitable planning (private foundation/DAF to avoid estate tax)
– Key-management protocols
– Digital asset instructions for executors
– Professional valuation before death
– Liquidity planning to pay taxes
Most crypto millionaires have none of these.
10. THE MINI FAMILY OFFICE™ SOLUTION SUITE
How High-Net-Worth Families Prevent a “Mellon Catastrophe” Using Entities, Planning, and AI Coordination

A preview of our proprietary Estate & Tax Planning and Visualization Portfolio Tool – to help you gain clarity and avoid mistakes.
The solution to this problem comes down to one word: ALIGNMENT.
The Mellon case demonstrates a core truth you teach inside the Mini Family Office™: Wealth is rarely lost because of market collapse; it is lost because of structural failure.
Crypto, real estate, business equity, private investments, intellectual property, and digital assets all collapse at the intersection of:
– Estate law
– Tax law
– Business entity law
– Risk management
– Timing
– Liquidity
– Market volatility
The Mini Family Office™ solves that collapse by creating a unified architecture, not a siloed “piecemeal” plan.
Below, I will present an alternative pathway to “generating, protecting, and preserving” wealth across all fronts. We’ll tackle all the issues in Mellon v. IRS case – as every single one of those “rules and regulations” ALSO apply to you.
The law is not “separate” for millionaires and billionaires – don’t fall for that marketing hype – your estate can face the same “legal process” that we explored above.
Below, I’ll present an operating model that I call “Flow Like Water” – taking in the philosophies of Bruce Lee – Water flows downstream and takes the path of least resistance. It does not try to breakdown the obstacles in the way, but it flows around it.
This is a mindset shift – one that allows you to lower friction, resistance, and also help you avoid scams, fraudsters, and Ponzi schemers that you’ll face along the way.
A. ENTITY STACK STRUCTURING
A deliberate legal entity stack lowers and prevents IRS valuation attacks, liquidity crises, probate disasters, and executor chaos.
1. Operating LLC (Digital Asset LLC)
Holds:
– crypto wallets
– cold storage
– digital contracts
– nodes/validators
– exchange accounts
– licensing rights
Benefits:
– separates digital assets from personal estate
– allows interest gifting
– enables valuation discounts legitimately
– creates clean FMV boundaries
– permits professional management
– reduces IRS visibility into personal holding patterns
2. IDGT (Intentionally Defective Grantor Trust)
Best structure for large crypto.
Employees:
– freezes value for estate tax purposes
– future appreciation stays outside the estate
– units/interests giftable at discounted valuation
– trustee control without triggering §2036 or §2038 inclusion issues
3. Dynasty Trust / Multi-Generational Trust
Crypto is extremely high-growth.
Legacy trusts prevent 40% estate tax every generation.
Mellon’s estate would have preserved over $40M–$80M per generational transfer.
4. FLP (Family Limited Partnership)
Excellent for crypto positions.
Used for:
– valuation discounts
– centralized investment management
– passing minority interests to children
– audit defensibility
5. Private Foundation Layer (The Philanthropy Lever)
In my Humble Opinion – This is the single largest tax arbitrage tool Mellon did not use.
A foundation solves the exact IRS valuation nightmare by:
– transferring appreciated crypto into a tax-exempt entity
– avoiding all capital gains on liquidation
– bypassing estate tax
– providing ongoing control (completely legal under §4940-§4945 rules)
– instantly solving liquidity constraints
– bypassing the probate process and court interference
B. TAX BLUEPRINT AND LIQUIDITY SUITE
Preventing Mellon’s Post-Death Liquidity Crisis
The Mini Family Office™ requires a pre-engineered Tax Liquidity Blueprint, which includes:
1. Pre-death valuation protocols
Crypto requires:
– quarterly valuations
– forensic access documentation
– discount analysis
– “restriction memoranda”
This makes estate tax FMV defensible.
2. Pre-arranged liquidity facilities
– structured life insurance
– pre-approved credit lines
– liquidity tranches linked to entity value
– foundation liquidation strategy
– multi-exchange liquidation rules
– protective hedging
This prevents forced sales under duress.
3. Integrated tax simulations
Every large asset class is pre-modeled under:
– market spikes
– market crashes
– regulatory freezes
– wallet-loss scenarios
– IRS audit triggers
We’ve already built the tax-death simulations with a range of Tax Iceberg™ tools. These strategies and tools would have saved the Mellon estate tens of millions.
C. DIGITAL ASSET GOVERNANCE
Mellon’s estate collapsed because of access issues — not because of XRP.
The Mini Family Office™ standardizes:
1. Key-Management Protocols
– assignments and transfers
– threshold signatures
– institutional custody
– executor passphrases
– encrypted backups
– timed key-release structures
2. Wallet Governance Charter
Document defining:
– who can transact
– who can liquidate
– who can audit
– disaster recovery process
– compliance logging
3. Digital Asset Will + Executor Instruction Set
This single document would have prevented 80% of the Mellon issues.
D. RISK MANAGEMENT + MULTI-ASSET COORDINATION
Crypto interacts with all other categories:
– real estate
– business equity
– trusts
– insurance
– litigation/subpoena risk
– bankruptcy risk
– tax enforcement risk
The Mini Family Office™ pulls these into one coordinated system, allowing:
– unified reporting
– gap detection
– advanced tax reduction
– multi-jurisdiction protection
– liquidity sequencing
TIP: To beat probate and the various layers of taxes that are imposed on your estate, you must treat each asset independently AND also as a part of your entire estate.
That’s how the law treats it, anyway.

13. THE CLOSING ARGUMENT: WHY MELLON’S CASE IS THE WARNING SHOT OF THE NEXT DECADE
The Matthew Mellon estate case is not about crypto.
It is about the collapse of fragmented professional advice.
He had:
– no estate liquidity plan
– no entity structuring
– no trust freeze
– no discount-protected ownership
– no philanthropic tax shield
– no digital governance
– no executor key-access plan
– no AI-driven valuation
– no Mini Family Office™ model
The result:
– tens of millions in additional estate tax exposure
– valuation litigation
– delayed administration
– asset loss
– public drama
– legacy erosion
This is what we are on a mission to solve.
Well – that’s it for me.
I hope you’ve found this case and this comprehensive guide informative, educational, and worthy of bookmarking and sharing with your community as well – because we’re all in the same boat.
