Structure Your Estate Before You Sell Your Business

Selling your business is probably the biggest financial event of your life, and for most founders it lands exactly once. You spent years, sometimes decades, building the value up. You get a single shot at deciding where it goes. And how much of it your family keeps, versus how much the tax authorities take, gets settled in the run-up to closing, well before the wire ever hits.

Before you call a banker or take a meeting with a buyer, sit 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 genuinely want to step away from the thing? And how do you keep the tax bill from running bigger than it has to? Your answers shape most of what comes next.

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

The temptation is to start with the headline, the price some buyer might pay. Start with your own needs instead. Work out, honestly, the capital it takes to fund your lifestyle for the rest of your life, and build in a cushion for whatever you didn't see coming. Plenty of owners are surprised how much their spending climbs once they've sold and suddenly have time on their hands and a boat they didn't used to own.

Whatever's left after that need is covered is your surplus, and the surplus is the wealth you can actually plan to give away. You can't gift what you might have to live on, so this is the number that comes first.

Move Value Before The Sale, Not After

Here's the part most owners miss. The best moment to transfer ownership is while the business is still yours and its value is still, as far as the tax code is concerned, an estimate instead of a signed price. Gift shares to your children or into a trust before a sale, while a defensible valuation discount still holds, and you can move real value out of your estate at a lower tax cost.

A grantor retained annuity trust, or GRAT, along with various irrevocable trusts, lets you hand future appreciation to the next generation on little or none of your lifetime exemption. The moment a letter of intent gets signed and a real price is sitting on the table, that room to maneuver shrinks fast. The discount fades. The value you could have moved on the cheap is now locked at the sale price.

There's a more advanced version of the same idea. You sell shares to an intentionally defective grantor trust and take back a promissory note. You freeze the value at today's discounted price, the trust pays you back over time at a low interest rate, and everything the business earns above that rate builds up for your heirs outside your estate. Because it's a grantor trust, the sale throws off no capital gain, and the income tax you keep paying on the trust's earnings works as one more tax-free transfer to the next generation. And the discounts for lack of marketability and control on a minority interest in a private company push the entry price lower still.

Use The Exemption While It Is High

There's a quieter risk most owners never bother to weigh. The lifetime gift and estate tax exemption is sitting at a historic high, made permanent by the 2025 law at roughly fifteen million per person, so the amount you can move out of your estate today, free of transfer tax, is unusually large right now. Permanent, though, is a softer word than it sounds. An exemption lives and dies by statute, and a future Congress can cut it back down just as easily as an earlier one pushed it up. The families who put a generous exemption to work while it's still generous rarely look back and wish they hadn't. The ones who treat that number as a sure thing are really just guessing, and hoping the guess holds until they need it.

Mind The Tax Before The Wire Hits

The sale itself kicks off a capital gains bill, and for a lot of founders it's the single biggest check they'll ever write. You can soften it, but most of the tools have to be set up before closing. If your company clears the bar for qualified small business stock under Section 1202, part of your gain may come out entirely tax-free, though the holding-period and eligibility rules are strict, and you'll want to confirm you qualify early rather than late.

Charitable giving, whether through a donor-advised fund or a charitable remainder trust, can offset gain in the year you sell while funding whatever causes you care about. None of this works as a last-minute scramble. These are calls you make while there's still time on the clock to make them.

The Window Closes At Signing

The thread running through all of this is timing. Estate and tax planning around a sale isn't a step you bolt on at the finish. It's the foundation you pour before the process even starts. The owners who keep the most, and lose the least sleep, tend to be the ones who did the work a year or two out, back when the term sheet was still a rumor.

A sale produces a number. What that number goes on to do for a family is a long chain of decisions, and nearly all of them are easier to make before the money lands than after. The real question goes past what your business is worth. It's what you want that value to actually do, for your family, for the next generation, for the causes you care about. Getting there takes a team that can see the whole board and work the deal, the estate, the tax, and the family off one shared plan. That's the work worth starting well before you feel ready to sell.
