For years a founder's wealth sits in one place, the company. After a sale it sits in cash, public securities, rollover equity or an earnout, and the planning that worked for an operating business no longer fits. Many founders are surprised by how quickly the questions change from valuation to ownership: who holds this money, under what documents, and what happens to it if something goes wrong.
Start before the closing
The most useful planning happens before the purchase agreement is signed. Gifts of company shares to family members or trusts are valued at the company's value on the date of the gift, so a gift made ahead of a sale can be treated very differently from a gift of the proceeds afterward. Whether that works depends on facts and timing, and it needs tax counsel working alongside the deal team.
Decide who owns what
Proceeds that land in one personal account are exposed to creditors, divorce and probate. Founders commonly move part of the proceeds into trusts for a spouse, children or a charitable purpose, and keep the rest for their own spending and further investment. New York imposes its own estate tax in addition to the federal one, and its threshold is lower than the federal exemption, so a New York resident can owe state tax at a level where federal tax is not yet a concern.
Plan for liquidity and for a different life
Life insurance owned by an irrevocable trust is one tool for providing liquidity to an estate without adding to its taxable value. It is not right for every family, and the policy has to be sized to a real need. Alongside the legal structure sits a personal question. A founder who has run a company for twenty years often has no plan for the next ten, and an earnout or a transition agreement can keep them tied to the buyer longer than expected.
A short list to work through
Name the people who will make decisions if you cannot. Put the proceeds under a written investment policy before making any large purchase. Review beneficiary designations on every account and policy. Decide how much you want your children to know, and when. Revisit all of it after the first year, once the earnout terms and your own spending are clear.
