Structure Your Estate Before You Sell Your Business

Selling your business is likely the largest financial event of your life, and for most founders it happens only once. You spent years, sometimes decades, building the value. You get one chance to decide where that value goes. The work that determines how much of it your family keeps, and how much goes to taxes, happens before the sale closes, not after.

Before you talk to a banker or entertain a buyer, it is worth sitting with a few questions. How much do you actually need to keep to live the life you want? What do you want to leave behind, and to whom? When do you truly want to step away? And how do you keep the tax bill from being larger than it needs to be? The answers shape everything that follows.

Start With What You Need, Not What You'll Get

It is tempting to begin with the headline number, the price a buyer might pay. Begin instead with your own needs. Estimate the capital required to fund your lifestyle for the rest of your life, honestly, and with a margin for the unexpected. Expenses often rise after a sale, not fall.

What remains after that need is met is your surplus, and surplus is the wealth you can plan to transfer. You cannot give away what you may need to live on, so this number comes first.

Move Value Before the Sale, Not After

Here is the part most owners miss. The best time to transfer ownership is while the business is still yours and its value is still, in the eyes of the tax code, an estimate rather than a signed price. Gifting shares to your children or into a trust before a sale, while a defensible valuation discount still applies, can move meaningful value out of your estate at a lower tax cost.

Structures such as a grantor retained annuity trust, or GRAT, and various irrevocable trusts let you pass future appreciation to the next generation while using little or none of your lifetime exemption. Once a letter of intent is signed and a price is on the table, that flexibility narrows quickly. The discount fades, and the value you could have moved cheaply is now fixed at the sale price.

There is a more advanced version of the same idea: selling shares to an intentionally defective grantor trust in exchange for a promissory note. You freeze the value at today's discounted price, the trust repays you over time at a low interest rate, and everything the business earns above that rate accrues to your heirs outside your estate. Because it is a grantor trust, the sale triggers no capital gain, and the income tax you pay on the trust's earnings is itself a further tax-free transfer to the next generation. The discounts for lack of marketability and control that apply to a minority interest in a private company make the entry price lower still.

Use the Exemption While It Is High

There is also a quieter risk most owners never weigh. The lifetime gift and estate tax exemption sits at a historic high, made permanent by the 2025 law at roughly fifteen million per person, which means the amount you can move out of your estate today, free of transfer tax, is unusually large. Permanent is not the same as fixed. An exemption is a creature of law, and a future Congress can lower it as easily as an earlier one raised it. The families who use a generous exemption while it is generous rarely regret it. The ones who treat it as guaranteed are making an assumption, not a plan.

Mind the Tax Before the Wire Hits

The sale itself will generate a capital gains bill, and for many founders it is the single largest check they will ever write. There are ways to soften it, and most of them must be in place before closing. If your company qualifies as qualified small business stock under Section 1202, a portion of your gain may be excluded entirely, though the holding-period and eligibility rules are strict and worth confirming early.

Charitable giving, through a donor-advised fund or a charitable remainder trust, can offset gain in the year of sale while funding the causes you care about. None of these are last-minute moves. They are decisions to make while you still have time to make them.

The Window Closes at Signing

The theme running through all of this is timing. Estate and tax planning around a sale is not a step you bolt on at the end. It is the foundation you build on before the process begins. The owners who keep the most, and worry the least, are the ones who did the work a year or two ahead, not the week the term sheet arrived.

A sale is a number. A legacy is a decision. The question is not only what your business is worth, but what you want that value to do: for your family, for the next generation, and for the causes that matter to you. Getting there takes a team that sees the whole picture, working the deal, the estate, the tax, and the family from the same plan. That is the work worth starting long before you are ready to sell.
