A family office client walked into our offices last September with a problem that perfectly captures the state of institutional crypto in 2026. They’d accumulated a digital asset portfolio worth roughly $40 million across Bitcoin, Ethereum, and several DeFi positions. Their traditional advisory team had structured everything under a single-member LLC in Delaware. The client’s estate plan hadn’t been updated since 2021. Nobody had considered the tax treatment of staking rewards. And the private keys sat in a hardware wallet in the CFO’s home safe.
This is not an unusual situation. It is, in fact, closer to the norm than most wealth managers want to admit.
The Rush to Allocate Without the Structure to Support It
Family offices have moved from skepticism to conviction on digital assets with remarkable speed. The regulatory frameworks in the EU (MiCA) and the evolving US posture under the current administration have removed the biggest objection most fiduciaries had. Institutional custody solutions from the likes of Coinbase Prime, BitGo, and Fidelity Digital Assets have eliminated the operational excuses. And the macroeconomic argument (that a portfolio of traditional 60/40 stocks and bonds faces structural headwinds from sovereign debt levels and currency debasement) has pushed allocations from “experimental” to “strategic.”
The problem is that the structuring hasn’t kept pace with the allocation. Families are buying crypto with the enthusiasm of retail investors and the governance of a checking account. The advisory industry bears significant blame here. Most traditional wealth advisors lack the technical knowledge to structure digital asset holdings properly, and most crypto-native advisors lack the tax and estate planning depth to build durable frameworks.
The result is a growing population of wealthy families sitting on substantial digital asset positions inside structures that will cost them enormously when tested by a tax audit, a divorce, a death, or a lawsuit.
Personal Ownership: The Worst Structure for the Biggest Position
We still encounter family office principals who hold crypto in personal wallets or on exchange accounts under their own name. The reasoning usually amounts to some combination of “I like the control” and “my advisor said it was fine for now.” It is not fine. Personal ownership of digital assets creates maximum liability exposure, maximum tax complexity, and minimum estate planning flexibility.
Every asset tied to an individual becomes discoverable in litigation. High-net-worth individuals face statistically elevated litigation rates, roughly seven times higher than the general population according to data from the American Bar Association. Crypto held personally is attached to the individual’s estate with no separation, no governance layer, and no transfer mechanism beyond the probate process that your heirs may or may not be able to navigate.
Then there’s the tax dimension. Personal ownership means every transaction (every swap, every staking reward, every DeFi yield farming event) generates a taxable event attributed directly to the individual. In the US, the IRS has gotten materially better at tracking on-chain transactions since the infrastructure provisions of the 2021 Infrastructure Investment and Jobs Act took effect. The 1099-DA reporting requirements that became mandatory for exchanges in 2025 have closed most of the information gaps. Personal ownership offers no tax planning flexibility: no ability to time gains across entities, no ability to use entity-level elections, no ability to separate trading activity from long-term holdings.
The LLC Trap: Delaware Isn’t Always the Answer
Delaware LLCs have become the default vehicle for crypto holdings, and for most family offices, that default is wrong. We say this as practitioners who routinely use Delaware entities in other contexts. The problem is specific to how digital assets behave.
A single-member Delaware LLC provides liability protection and a modicum of privacy (though less than most people think since the Corporate Transparency Act’s beneficial ownership reporting requirements). What it doesn’t provide is meaningful tax flexibility. A single-member LLC is a disregarded entity for federal tax purposes, so all income flows through to the individual owner. You’ve added a layer of complexity without gaining any structural advantage.
The more sophisticated approach, which we’ve implemented for several clients, involves a multi-entity framework tailored to the investment strategy. Long-term hold positions (Bitcoin, primarily) sit in one entity. Active trading and DeFi activity sit in another. Staking operations, which generate ordinary income, sit in a third. Each entity can make different tax elections. Each has its own risk profile. A catastrophic smart contract failure in DeFi doesn’t contaminate the long-term Bitcoin holdings. A lawsuit arising from trading activity doesn’t reach the staking income.
Wyoming has become genuinely relevant here, and not just for the crypto-friendly reputation. The Wyoming DAO LLC statute, amended in 2024, provides a legal framework for entities that interact with decentralized protocols. The state’s lack of income tax simplifies the state-level analysis. And the LLC asset protection provisions are among the strongest in the US. For families that want domestic structuring, Wyoming deserves serious consideration as the domicile for the active entities, with Delaware or Nevada for the holding company layer above.
Custody Architecture Is a Governance Problem, Not a Technology Problem
The custody question has evolved beyond “where do we store the keys?” The technology is mature. Multi-party computation (MPC) wallets from institutional providers offer security that’s genuinely comparable to traditional custodians. The question that most family offices get wrong is who controls the keys and under what governance framework.
We’ve reviewed custody arrangements where the CIO has unilateral access to move nine-figure positions. We’ve seen setups where the passphrase recovery documents sit in the same physical location as the primary hardware wallets. We’ve encountered family offices where the only person who understands the DeFi positions is a 28-year-old analyst who could leave next month.
The governance framework needs to match what you’d apply to any concentrated, illiquid position of comparable size. That means multi-signature requirements calibrated to the transaction size. It means documented succession procedures for key holders. It means regular attestation reviews where the governance committee verifies that the custody controls match the policy. And it means segregation between the team that manages the portfolio (investment decisions) and the team that controls custody (operational security). When the same person decides what to buy and has the ability to move the assets without oversight, you have an embezzlement risk that no amount of blockchain transparency eliminates.
Estate Planning: The Problem That Gets Worse Every Year You Ignore It
Digital assets break traditional estate planning in ways that most estate attorneys still don’t fully appreciate. The core issue is that crypto doesn’t behave like other assets at death.
When someone dies holding publicly traded securities, the executor contacts the brokerage, provides a death certificate, and the assets transfer to the estate. The process is bureaucratic and slow, but it works. When someone dies holding the private keys to a crypto wallet, the executor needs to find the keys, understand how to use them, and successfully transfer the assets. If they can’t, the assets are gone permanently. “Permanently” is not an exaggeration. Chainalysis estimates that approximately 20% of all Bitcoin is irretrievably lost, much of it due to deceased holders whose heirs lacked access.
The estate planning framework needs three components that most families haven’t implemented. First, a digital asset inventory that’s maintained separately from the estate plan but referenced within it. Think of it as a living document that lists every wallet, exchange account, DeFi position, and staking arrangement, updated quarterly. Second, a succession protocol that specifies how key access transfers at incapacity or death, including the technical steps required and the identity of the person or people authorized to execute them. Third, an entity structure that allows the digital assets to pass outside of probate entirely. Probate is public, slow, and creates a window where assets sitting in hot wallets are vulnerable.
The tax dimension of estate planning for digital assets adds another layer. The step-up in basis at death under current US tax law (Section 1014) applies to digital assets, which means unrealized gains disappear if the assets are held until death. For families with large unrealized gains in Bitcoin or Ethereum, this creates a legitimate planning consideration: the tax benefit of holding until death versus the concentration risk of maintaining an oversized position. The answer depends on the family’s overall estate size, the proportion of digital assets to total wealth, and the state of the stepped-up basis provision (which has been politically contested for years and could change).
The MiCA Factor: European Families Face Different Rules Now
For European family offices, the Markets in Crypto-Assets Regulation (MiCA) that went into full effect in late 2024 has fundamentally changed the compliance burden. MiCA imposes licensing requirements on crypto-asset service providers, including some activities that family offices previously treated as exempt.
The question that keeps coming up in our European client conversations is whether the family office’s DeFi activity constitutes a “crypto-asset service” that triggers MiCA registration. The answer depends on the specifics: whether the family office is acting purely for its own account, whether it’s pooling capital from multiple family members, and whether any of its activities could be characterized as providing services to third parties. The safe harbor for purely proprietary activity exists but is narrower than many families assumed.
We’ve also seen European families blindsided by the interaction between MiCA and existing national tax frameworks. Germany’s treatment of crypto held for more than a year (tax-free capital gains) remains attractive but comes with increasingly strict documentation requirements. France’s flat tax on crypto gains is straightforward in principle but complicated by DeFi activity that French tax authorities are still developing guidance on. The Netherlands’ wealth tax regime (Box 3) applies to the total value of crypto holdings regardless of whether gains are realized, which creates a liquidity problem for families with large positions relative to their cash flow.
Staking Income: The Tax Classification Nobody Has Figured Out
Staking rewards represent an unresolved tax classification problem that affects every family office with proof-of-stake positions. The fundamental question is whether staking rewards are income when received (like interest or dividends), or whether they’re newly created property (like a baker pulling a loaf out of the oven) that isn’t income until sold.
The Jarrett case in the US (2024) suggested the “creation of new property” theory had merit, but the IRS didn’t concede the point broadly, and Revenue Ruling 2023-14 maintained that staking rewards are ordinary income when received. This creates a practical problem: families owe tax on staking rewards at the fair market value when received, even if the value subsequently drops. We’ve seen clients owe significant tax on staking rewards received during a market peak that were worth a fraction of that amount by filing time.
Our approach has been to segregate staking activity into a separate entity that makes the appropriate tax elections and to maintain contemporaneous valuation records that can support a reasonable position on timing and value. The entity-level separation also insulates the staking income from the capital gains treatment of the long-term holdings.
What a Proper Framework Looks Like
For families with digital asset portfolios above $5 million, we recommend a framework that addresses four layers: entity structure, custody governance, tax management, and estate integration.
The entity structure separates holdings by investment strategy and tax character. The custody governance maps every wallet and account to a policy that specifies authorized signers, transaction limits, and succession procedures. The tax management system tracks cost basis across every entity and every asset, updated in real-time rather than reconstructed at year-end. And the estate integration embeds the digital asset plan into the broader family governance structure, including the family constitution or governance charter if one exists.
None of this is technically difficult. The challenge is that it requires coordination across three or four different professional disciplines (tax, legal, technology, and investment management) that rarely talk to each other and have no shared framework for digital assets. The tax advisor doesn’t understand multi-sig custody. The technologist doesn’t understand estate tax. The estate attorney doesn’t understand DeFi. And the investment manager is focused on returns, not structure.
That coordination gap is where the real risk lives. Not in the volatility of the assets themselves; families who’ve allocated to crypto have generally accepted that risk. The structural risk is what keeps us busy. The possibility that a perfectly good investment generates a terrible outcome because the plumbing around it was built wrong. And it’s what should keep family offices awake until they’ve addressed it properly.
