Mega Business Sale Over $50 Million: Estate Planning and Philanthropy

Over $50M, coordinate with a multi-disciplinary team to implement philanthropic vehicles, dynasty trusts, and defensible tax strategies. IRS scrutiny is likely.

IRS scrutiny is near certain. The IRS Large Business and International division and its high-wealth compliance campaigns flag transactions of this size. Every position taken must be defensible, well-documented, and consistent across all related filings.

Philanthropic vehicles at scale. Private foundations, donor-advised funds, and charitable lead trusts can redirect a meaningful portion of the tax bill toward causes you choose. A pre-sale contribution of appreciated business interests to a private foundation generates a deduction at fair market value (subject to AGI limits under Section 170) and eliminates capital gains on the contributed portion.

Dynasty trusts and wealth transfer. Irrevocable trusts funded before the sale can lock in the current estate tax exemption and move future appreciation outside your taxable estate. Generation-skipping transfer tax planning under Section 2601 becomes essential at this asset level.

The pitfall: Advisors at this level sometimes over-engineer structures that create ongoing compliance burdens or trigger anti-abuse provisions. The CPA's role is partly to keep the strategy defensible and operationally manageable for decades, not just to minimize the year-one tax bill.
