A successful sale moves a meaningful chunk of net worth in one transaction. Without estate planning, you can solve a business problem and create a tax-and-family problem.
Step-up in basis at death. Heirs receive assets at the fair-market value at date of death, eliminating built-up capital gains. For older sellers, holding the business until death (with strong succession in place) can wipe out the entire embedded gain. Trade-off: holding requires staying engaged or building real management, and IRS rules around "step-up" continue to evolve.
Trusts before sale. Transferring some equity to an irrevocable trust *before* signing an LOI can shift future appreciation outside your taxable estate. Done after the LOI, the IRS may unwind it. This is months-of-planning territory, not days.
Charitable strategies. Donating appreciated equity to a Donor-Advised Fund (DAF) or Charitable Remainder Trust (CRT) before a sale can both reduce capital gains and create deductions. Most useful for sellers who were planning charitable giving anyway and have strong gain (>30% of sale price).
Family involvement. If a family member (spouse, child) will inherit or co-own going forward, get them named on documents now, not at the funeral. Misalignment between the operating spouse and the non-operating spouse is the most common source of estate disputes in small businesses.
Beneficiaries on accounts. Update bank, brokerage, retirement, and insurance beneficiaries to reflect post-sale wealth distribution intent. Most sellers forget this for a year and create unnecessary risk.
