Selling in the next few years? The planning window is open now.

For an owner planning to sell in the next few years, the single most valuable input to tax planning is not a clever structure. It is time. Nearly every meaningful strategy available to a seller either requires a holding period, works best before the company has a negotiated price, or takes months to implement well. The variable your outcome turns on is how early the planning starts relative to the closing date.

Does my stock qualify for the QSBS exclusion, and what changed?

If your company is a C corporation and meets the requirements of Section 1202, qualified small business stock can exclude an enormous amount of gain from federal tax. For stock acquired on or before July 4, 2025, the old rules apply: hold for more than five years and exclude up to the greater of $10 million or ten times basis. For stock acquired after that date, the 2025 tax law replaced the five-year cliff with tiers: 50 percent of gain excluded at a three-year hold, 75 percent at four years, and 100 percent at five, with the dollar cap raised to $15 million. Two practical consequences follow. First, your acquisition dates now matter enormously, and different lots of your own stock may live under different rules. Second, because the exclusion cap is per taxpayer, gifting shares to family members or trusts well before a sale can multiply the exclusion across your family. That word, before, is doing all the work.

What can trusts actually do for me here?

Two structures come up in nearly every exit we plan. A charitable remainder trust lets you contribute appreciated shares before the sale, diversify inside the trust without immediate capital gains, draw an income stream for years, and leave the remainder to charity. An installment sale to an intentionally defective grantor trust can move future appreciation of the business out of your taxable estate while you keep the income tax burden, which is itself a further transfer. Both share a defect and a feature: they must be in place, and genuinely so, before the transaction is a foregone conclusion. A trust funded the week after a signed letter of intent invites the IRS to look straight through it.

What about the deal itself?

Asset sale versus stock sale, earnout structure, rollover equity, the state you sell from: each of these moves your after-tax number, and each is negotiated at a table where your CPA, your attorney, and your banker all hold one piece. The most expensive version of an exit is the one where those three professionals meet each other for the first time during diligence. Someone has to hold the whole picture, and it should not have to be you in the most demanding year of your professional life.

When pre-sale planning works against you

Tax strategy should never drive the deal. Holding an extra eighteen months to reach a QSBS tier is only smart if the business and the market cooperate, and businesses have a way of not cooperating. Irrevocable structures are exactly that, and an owner who over-transfers before a sale that then falls through has given up flexibility for nothing. The honest rule: decide how much is enough for your family first, secure that, and let the strategies apply to what is above the line.

The principle to carry

Every strategy on this page gets weaker as the closing date gets closer, and most of them switch off entirely once a price is agreed. If a sale is plausible within five years, the planning conversation is not premature. It is on time.

Aspirean works with owners who are two to five years from a sale, which is when this coordination is worth the most. If a transaction is somewhere on your horizon, that is the moment to talk, not after the letter of intent arrives.

This piece is general education, not individual advice. Whether any of it applies to you depends on your specifics, which is exactly the conversation to have before acting.
