The Business Exit Window for Charitable Gifts: The Deal Closes It, Not the Calendar

Your client is three weeks from a signed purchase agreement and the deal looks good. You suggested a charitable gift of company stock, he likes the idea, and he told you he wants to wait until he is sure the sale is going to happen.

That instinct is reasonable, but it also narrows his options.

December 31 and the signature page are both real deadlines, but neither is the first to arrive. And the most important deadline is often overlooked: the exit window for charitable gifts closes at the point where the client stops carrying real risk that the transaction will fail. A client waiting for certainty is waiting for the exact condition that disqualifies the treatment he is trying to capture.

There are two separate constraints on a pre-liquidity gift. One is operational: a complex-asset gift needs roughly 90 to 120 days of runway to be completed by year-end, which is why the practical starting line is early September. The other constraint is the one below, and it can close months before the calendar does.

What actually closes the business exit window?

The loss of donor risk. A charitable gift of business interests must be made while the sale could still fail, and that point can arrive well before any date on the calendar.

For a gift of business interests to be recognized as a gift of property rather than recharacterized as a gift of sale proceeds, the client must still bear a meaningful chance at the time of transfer that the sale will not close. Once the client’s right to the proceeds has effectively hardened, the anticipatory assignment of income doctrine allows the gain to be taxed to the client even though the asset itself moved to charity first.

This is not a calendar test. It moves with the transaction, and it is invisible unless someone is watching for it.

Does completing the gift before the purchase agreement protect it?

No, not on its own. The belief that it does is the most common misunderstanding in exit planning.

That misunderstanding traces back to Revenue Ruling 78-197, a 1978 IRS ruling under which sale proceeds are taxed to the donor only where the charity was legally obligated to sell the contributed property. The Tax Court has never adopted that standard as its test for assignment of income. In Estate of Hoensheid v. Commissioner (T.C. Memo. 2023-34), the charity had no legal obligation to sell at the date of the gift, and the donor was taxed on the gain anyway.

The court held that a donor’s right to the income is fixed once the sale has become practically certain to occur, and that the charity’s legal obligation is only one factor in that analysis. It also weighed what the parties had already done to effect the transaction, which contingencies remained unresolved, and whether the required corporate formalities were still genuinely open. On these facts, large dividends and bonuses paid out before the gift showed the parties expected a close, the contingencies left in the draft documents were minor, and shareholder approval was a foregone conclusion.

Timing compounded the problem. The court found the gift was completed a full month later than the donor claimed because he waited until the sale was nearly final to decide how many shares to move and when to deliver them. His own communications supplied the evidence.

The same one-month gap also cost the deduction. The appraisal used the donor’s claimed contribution date rather than the date the court found, and in the interval the company had made those same large payouts, which changed what the shares were worth. The court found the appraiser was not a qualified appraiser and denied the deduction outright. The donor ended up taxed on the gain the gift was meant to avoid with nothing to show for making it.

The practical read for advisors: the date on the purchase agreement is not the line that matters. The question is whether the deal could still have died on the day the gift was made, and that determination belongs with the client’s tax counsel on the specific facts.

What if the sale lands in a different tax year than the gift?

The deduction is credited to the year the contribution is complete. The income is recognized in the year the sale closes. Those do not have to be the same year, and when they are not, the math changes considerably.

A gift completed in December 2026 against a February 2027 closing produces a 2026 deduction with no 2026 liquidity event to absorb it. Contributions of long-term appreciated property to a public charity are deductible at fair market value up to 30% of AGI, with excess carried forward up to five years under the carryover rules in IRS Publication 526. In a normal-income year, a large gift can spend years working through that carryforward instead of offsetting the gain it was meant to offset.

Sometimes the right answer is to complete the gift early and accept the carryforward because the deal-side window is closing. Sometimes it is to wait for the January transaction year. Run both years with the client’s tax advisor before choosing a transfer date.

What changed for a 2026 exit?

Two provisions of the OBBBA took effect January 1, 2026, and apply to any gift made this year:

• A 0.5% AGI floor on charitable deductions for itemizers. Contributions are deductible only above that threshold. The floor scales with AGI, so a large liquidity year produces a correspondingly large nondeductible slice.
• A 35% cap on the value of itemized deductions for top-bracket taxpayers. A deduction dollar previously worth 37 cents to these clients is now worth 35.

Neither changes the core mechanics. Both raise the value of landing the deduction in the year that actually carries the income.

What should you ask before the deal timeline hardens?

Four questions, and none of them are about philanthropy:

• Where is the process right now, and is the client under exclusivity with a buyer?
• Do the entity documents permit a transfer of this interest, and to a charitable holder specifically?
• Has anyone told the buyer, and will a charitable name on the cap table draw an objection during diligence?
• Who is being lined up to prepare the valuation, and is that person independent of the deal?

The answers determine whether a window exists. They take one conversation to gather and are harder to get after an agreement is signed.

Questions advisors ask most about exit timing

These questions come up in nearly every exit conversation, and they tend to surface later in the process than anyone would like. The short answers below offer some direction, but specific transaction questions will differ by client.

Is a signed letter of intent the point of no return?

Not automatically, and an unsigned one does not mean the window is still open. The analysis turns on whether the client still bears real risk that the sale will fail. That risk can disappear before a letter of intent is ever signed in a competitive process or survive well past signing in a fragile deal.

Can the gain be taxed to the client even though the charity received the asset?

Yes. That is the outcome in the Hoensheid case. The transfer was valid as a gift and the gain was still attributed to the client.

Does the strategy require selling the whole company?

No. Partial interests, minority positions, and recapitalizations can all support a pre-liquidity gift. Valuation and transfer mechanics differ, but the timing analysis is the same.

The client’s deal is already under a signed agreement. Is there anything left?

Possibly, depending on the facts and what is being sold. The worst outcome is a client who assumes the answer is “no” and closes without asking.

Ask while the answer can still change

If you have a business owner client with charitable intent and a transaction anywhere on the horizon, get a read on where the deal actually stands and whether the business exit window is still open. That read is quick, and the earlier it happens, the more options stay open.
