Print bio

Dan focuses on family office services, advanced trust design, and tax-efficient planning for modern portfolios including cryptocurrencies and other digital assets.

Dan Lewis advises multi-generational families on the formation and administration of family offices, such as entity selection and structuring, governance frameworks, investment and operating policies, information-rights protocols and risks, privacy, and cybersecurity considerations. He creates lasting frameworks that align decision-making and oversight with family values, helping ensure confidentiality and effective reporting.

A significant portion of Dan’s practice involves sophisticated trust and transfer tax planning, with depth in non-grantor trust strategies designed to optimize income-tax efficiency, asset protection, and control across jurisdictions. He structures and implements a wide range of vehicles—including intentionally defective grantor trusts, dynasty trusts, spousal lifetime access trusts, beneficiary defective/deemed owner trusts, grantor-retained annuity/unitrusts, qualified personal residence trusts, incomplete gift trusts, domestic asset protection trusts, directed trusts, silent/quiet trusts, and purpose trusts—to address tax minimization, succession, basis management, privacy, asset protection, and complex family governance needs. Dan frequently integrates trusts with closely held business interests, private funds, and alternative assets, tailoring fiduciary provisions, distribution standards, and administrative mechanics to the family’s objectives and risk profile.

Dan counsels clients on the full lifecycle of cryptocurrency and digital asset planning. His experience includes entity and trust design for on-chain and off-chain assets, custody and key management solutions, valuation and basis tracking considerations, cross-border and state tax implications, charitable and philanthropic structures, and tax reporting and compliance. He develops frameworks to facilitate secure transfers, liquidity events, and succession planning for wallets, exchange accounts, and tokenized interests.

Dan also leads privacy planning for families and individuals, designing structures to minimize public footprint and control information flows. His work involves entity layering, jurisdiction selection, trust situs strategies, registered agent and address hygiene, confidentiality and information-rights policies for family offices, secure communication and data governance, and cybersecurity coordination with advisers. He also addresses privacy issues in real estate acquisitions, philanthropic initiatives, and succession events, helping clients manage regulatory disclosures, media exposure, and digital data risks while preserving discretion.

In addition, Dan represents fiduciaries and beneficiaries in complex trust and estate administration, including probate and pre- and post-mortem planning, and advises on tax compliance and disputes with the IRS, Illinois Department of Revenue, and other taxing authorities. He is known for translating technical rules into practical, discreet solutions that protect family privacy and advance long-term generational goals.
