Before You Sign the Letter of Intent: Planning for a Business Sale

By Terry L. (T. L.) Turnipseed, J.D., LL.M., CTFA · October 29, 2026

Most of the estate and income tax planning available to a business owner has to be done before the sale process creates a hard valuation. The sale is the deadline. Planning creates the options.

The most expensive sentence a business owner can say to an estate planner is "we signed the letter of intent last month." Most of the planning that reduces estate tax, defers or eliminates income tax and protects the proceeds depends on acting before a sale process creates a hard valuation point and before any binding agreement exists. The sale is the deadline. Planning creates the options.

Start with what kind of company it is

The entity type decides which tools are even on the table. C corporation stock raises the qualified small business stock question immediately. S corporation stock raises eligibility questions for any trust that will own it. Limited liability company and partnership interests raise valuation, allocation and operating agreement questions. Then confirm basis, expected sale timing, existing insurance, charitable intent, family succession goals, control needs and state tax exposure. No single trust answers all of those; the strongest cases use a coordinated stack of two or three.

Move equity before the value is fixed

For a founder who says the company may sell in three to five years, the first conversation is usually a gift or sale of minority, nonvoting or LLC equity to a South Dakota asset protection trust or dynasty trust before the sale process begins. Future appreciation and the eventual sale proceeds shift outside the taxable estate, the trust adds asset protection for the founder and for descendants, and the proceeds land in a professionally administered trust rather than a personal brokerage account. Pre-sale transfers need appraisal support, defensible discounts, consistent deal documents, and a solvency review before any binding agreement or creditor issue exists.

Freeze the estate with a sale to a grantor trust

Where the company has strong cash flow and the family wants succession, the classic structure is a recapitalization into voting and nonvoting shares followed by a sale of discounted nonvoting stock or LLC interests to an intentionally defective grantor trust for a promissory note. The founder's estate is frozen at the note value, growth above the note passes to the trust, and because the founder pays the trust's income tax, the estate shrinks further without any additional gift.¹ For an S corporation the trust must be an eligible shareholder, which means watching grantor trust, ESBT and QSST rules.²

GRATs for volatile equity

Where the equity may appreciate sharply before the exit, a grantor retained annuity trust shifts the upside above the IRS hurdle rate with little or no taxable gift, and rolling or cascading GRATs repeat the bet.³ GRATs need time and upside before the sale is locked in, and the mortality risk, annuity administration and asset volatility have to be modeled.

Charitable tools for the sale year

A charitable remainder unitrust funded with a carefully selected slice of low-basis equity before the sale is legally fixed lets the trust diversify without immediate capital gain recognition, pays the founder or the couple a lifetime or term income, and leaves a charitable remainder.⁴ A grantor charitable lead annuity trust front-loads a charitable deduction into a high-income sale year while the trust makes annual payments to charity and the remainder passes to family trusts.⁵ Both require real charitable intent and careful modeling of deduction limits and payout rates.

Insurance for liquidity and buy-sell funding

When closely held stock is valuable but illiquid, when the estate may owe tax within nine months of death, or when partners rely on a buy-sell agreement that is not actually funded, an irrevocable life insurance trust provides the cash without forcing a quick sale of the company, and keeps the proceeds protected for the beneficiaries.⁶

Qualified small business stock, carefully

If the company is a C corporation and counsel confirms the stock qualifies, separate nongrantor trusts created early enough can each claim their own exclusion.⁷ The qualification tests, holding period, original issuance, gross assets, active business and trust taxpayer rules all have to be met, and the structure should be conservative and fact-driven rather than a mechanical multiplication exercise.

Two basis and state tax tools

A married founder in a separate property state can use a South Dakota community property trust so that both halves of the appreciated business receive a basis adjustment at the first spouse's death, which matters if a death occurs before the sale or before the proceeds are rebalanced.⁸ A founder in a high tax state may use nongrantor trusts for post-sale investment assets, with the caveat that resident trust rules, source income and beneficiary residence can change the outcome and nothing should be promised before it is modeled.

The order of operations

Confirm the entity type and basis. Get the appraisal. Run the solvency review. Choose one to three strategies, not ten. Coordinate corporate counsel, tax counsel, the accountant, the valuation firm, the insurance professional and the trustee before documents are signed. And do all of it before the letter of intent, because afterward the price is known, the buyer's lawyers are reading everything, and most of the options are gone.
