Wealth and tax planning around a sale is about what you keep and when, not only what a buyer pays. The bridge from sale price to net proceeds runs through fees, debt payoff, working capital, escrow, deferred consideration and tax, so two offers with the same headline price can leave very different amounts in hand. Much of the tax result is set years before a buyer appears: pre-sale tax planning is mostly a calendar problem, because the levers with waiting periods tend to close once a letter of intent is signed.
The levers run on different clocks. Qualified small business stock can exclude some or all of the federal gain, but S corporation and LLC equity does not qualify as it stands, so capturing the benefit usually takes a restructuring and years of holding. Installment sales spread gain across the years payments arrive, and state residency and sourcing rules can change the tax on the gain. Estate planning and charitable giving both lose options once a deal is effectively certain.
Other topics come up before a buyer arrives: tax cleanup such as unfiled returns and sales-tax exposure, what happens to your retirement plan, and the fact patterns that call for a tax specialist. After closing, rollover equity and seller notes keep part of the price tied to one company, and the first year has its own mistakes that repeat. None of this is tax or legal advice; the articles explain how the rules work so the conversation with your own CPA and attorney starts further along.

Frequently asked questions
- How much of the sale price do owners actually keep?
- It depends on the deal. The headline price is usually enterprise value, and fees, debt payoff, the working capital adjustment, escrow, deferred or contingent consideration and tax all sit between it and the cash in hand. That is why two offers with the same headline price can leave very different amounts.
- How early does tax planning for a sale need to start?
- A common rule of thumb is to begin one to five years before a likely sale. The longest-lead items are entity structure and qualified small business stock holding periods, which can take three to five years or more, and once a letter of intent is signed, installment structuring and purchase price allocation are among the few levers left. None of it is do-it-yourself work, so the details belong with your own CPA and tax attorney.
- Why does timing matter for gifts and charitable donations around a sale?
- Under the assignment-of-income doctrine, once a sale is effectively certain, moving the gain to a family member, a trust or a charity generally stops working, and the owner can still be taxed on it. Estate transfers are valued by appraisal before a buyer prices the company, often at discounts, and afterward they are measured against the deal price. These are fact-specific questions for qualified counsel and a CPA.
