Charitable Giving Before a Share Sale: Review the Gift Before the Deal Is Finished

The short version

Donating appreciated shares can support a charity and change the tax result of a planned sale. The analysis has two separate questions: whether the donor remains taxable on the sale gain, and whether the gift produces an allowable charitable deduction. Completing one part does not establish the other.

Sheepdog Tax can review the proposed transfer, sale timeline, deduction limits, and required records before a donor relies on estimated tax savings. For individual donors in 2026, the new charitable deduction floor and the limitation affecting top-bracket itemized deductions belong in that projection.

Establish the deduction and the recipient

Internal Revenue Code section 170 governs the deduction. This article focuses on an individual’s outright gift of appreciated investment shares to a qualifying public charity, including a qualifying sponsoring organization for a donor-advised fund. Under section 4966(d)(2), a donor-advised fund is an account maintained by a charitable sponsor in which the donor may retain advisory privileges; the sponsor must have legal control of contributed assets. Private foundations, split-interest trusts, and gifts of partnership or S corporation interests need separate analysis.

For eligible long-term capital-gain property given to an organization described in section 170(b)(1)(A), fair market value can be the deduction starting point, subject to the applicable limits. The usual percentage ceiling for that category is 30 percent of the donor’s contribution base. Contribution base generally means adjusted gross income, or AGI, computed without a net operating loss carryback. The statute provides a different election that can trade a reduced property deduction for different percentage-limit treatment; it should be modeled rather than assumed advantageous.

Holding the shares for one year or less can change the result. Section 170(e)(1)(A) reduces the deduction by gain that would not be long-term capital gain if the property were sold at fair market value. Appreciated short-term investment shares therefore generally produce a basis-level deduction rather than a deduction for their full value. Employee awards require an additional review of compensation, vesting, basis, and transfer restrictions before applying the investment-stock model.

A gift just before closing is not automatically early enough

The anticipatory-assignment-of-income doctrine can leave the donor taxable when the right to sale proceeds has become fixed before the gift. In Estate of Hoensheid v. Commissioner, T.C. Memo. 2023-34, pages 27 through 34, the Tax Court examined whether the sale was virtually certain when the shares were donated. It considered legal obligations, steps already taken, unresolved contingencies, and corporate formalities. The donor was taxable on the gain even though the court did not find that the charity was legally obligated to sell.

That holding does not create a universal number of safe days before closing. Nor does it establish that any unsigned purchase agreement leaves the planning window open. Counsel and the tax adviser need the actual chronology: negotiations, approvals, tender or sale commitments, transfer documents, charity acceptance, and remaining conditions. The date the donor first discussed a gift is not necessarily the date a completed transfer occurred.

Hoensheid also illustrates the separate substantiation risk. The court found a valid gift but denied the claimed charitable deduction because the appraisal requirements were not satisfied. A donation can therefore leave the donor with both taxable gain and a denied deduction. The opinion’s historical facts are a caution about documentation and timing, not a statement that every pre-sale gift fails.

Apply the 2026 floor and deduction limitation

For taxable years beginning after December 31, 2025, section 170(b)(1)(I) allows otherwise deductible individual charitable contributions only to the extent their aggregate exceeds 0.5 percent of contribution base. This is an annual aggregate floor, not a new floor for each gift. The statute specifies ordering among contribution categories.

The floor also has a carryforward restriction. Section 170(d)(1)(C) generally adds the floor-disallowed amount to a carryforward only in a year in which an excess is already carried forward under an applicable charitable percentage-limit rule. Do not assume that every amount lost to the floor will become deductible later.

Section 68, also effective for taxable years beginning after December 31, 2025, then reduces otherwise allowable itemized deductions by 2/37 of the lesser of those deductions or the specified income excess above the start of the 37 percent bracket. It operates after other deduction limits. Where that reduction applies in full to deductions that otherwise offset income taxed at 37 percent, their federal income-tax benefit is effectively 35 percent. That is not a flat benefit rate for every donor or every dollar donated.

A hypothetical 2026 stock gift

Assume an individual has a $1 million contribution base and gives long-term investment stock worth $100,000, with $20,000 basis, to a qualifying public charity in 2026. These are invented teaching figures. Assume the outright gift is completed before any fixed right to sale proceeds, fair market value is supported, all substantiation is satisfied, there are no other charitable gifts or carryovers, and the gift qualifies for the ordinary 30 percent capital-gain-property limit.

The percentage ceiling is $300,000, so it does not limit this $100,000 gift. The 0.5 percent floor is $5,000. The charitable deduction remaining after that floor is $95,000, before section 68. Because no applicable percentage-limit excess is carried forward in this example, the $5,000 lost to the floor does not create a carryforward under section 170(d)(1)(C).

If the donor’s complete return also places all $95,000 within the full section 68 reduction and it otherwise offsets income taxed at 37 percent, the deduction’s federal regular income-tax benefit is $33,250: $95,000 multiplied by 35 percent. The same calculation is $95,000 multiplied by 35/37 to determine the deduction remaining after section 68, then multiplied by 37 percent. It is not $100,000 multiplied by the donor’s highest tax rate.

The shares contain $80,000 of appreciation. This example does not assign a tax-saving rate to that appreciation or add a second estimated benefit. The sale-gain analysis, any stock-specific exclusion, other taxes, state treatment, and the donor’s full return must be reviewed separately. The gift also transfers the shares away; a tax benefit does not reimburse the gift’s entire economic cost.

The paperwork thresholds are separate from the tax projection

The following figures come from section 170(f)(8) and (11), the Form 8283 instructions, and Publication 561. They concern an individual donor; exceptions and aggregation of similar items must be checked.

Publicly traded securities with readily available market quotations generally qualify for the appraisal exception, but that does not eliminate acknowledgment, value support, or applicable Form 8283 reporting. The current instructions generally use Section A for publicly traded securities and Section B for property subject to the qualified-appraisal requirement.

Publication 561 explains the appraisal timing rules, including the 60-day pre-contribution boundary and receipt of the appraisal by the relevant return deadline. The acknowledgment must be obtained by the earlier of filing the return or its due date, including extensions. For a donor-advised fund, section 170(f)(18) also requires acknowledgment that the sponsor has exclusive legal control over the contributed assets. A charity’s signature does not substitute for a qualified appraisal or establish the donor’s claimed value.

What to prepare before transferring shares

Sheepdog Tax’s review can bring together the proposed gift documents, issuer restrictions, stock-lot basis and holding periods, charity status and acceptance requirements, valuation support, sale chronology, and full-year income estimate. Counsel handles legal transfer requirements and evaluates the transaction commitments. A qualified appraiser, when required, must receive the facts needed to value the donated interest.

Passing On a Collection illustrates why a charitable transfer needs both a substantive tax analysis and a documentation file. Its related-use rules concern tangible personal property; they are not the stock rules applied here. This article’s current 2026 deduction discussion should govern the floor and section 68 questions addressed above.

The item-file approach in Recordkeeping for Collectors and Flippers can also help organize acquisition and basis evidence. For a share donation, add the actual transfer and acceptance records, required acknowledgment, appraisal, Form 8283 information, and sale-timeline evidence.

How Sheepdog Tax can help

Sheepdog Tax offers a scoped review of a proposed share donation’s tax timing, deduction limits, substantiation, and effect on the broader sale-year projection. Email noah@sheepdogtax.com with the expected transaction date and whether the gift has already occurred to discuss a secure records review.

Sheepdog Tax is a veteran-owned practice led by Noah Green, a certified public accountant (CPA) and Certified Fraud Examiner (CFE). A review does not guarantee a deduction or avoidance of sale gain. The Firm can identify the tax questions that need to be resolved with counsel, the charity, and any required appraiser before the transfer is completed.
