Gifting stock to charity works best when the shares have gone up in value and you’ve owned them more than a year: you transfer the shares directly to a qualified public charity, skip the capital gains tax you would owe on a sale, and, if you itemize, deduct the full fair market value of the shares against your income. Done correctly, one gift produces two separate tax benefits. Done carelessly, small mistakes at the brokerage or on the paperwork can wipe them both out.
The Two Tax Benefits, Side by Side
Selling appreciated stock triggers federal long-term capital gains tax at 0%, 15%, or 20% depending on income, and high earners owe an additional 3.8% net investment income tax on top of that, for a combined federal rate as high as 23.8%.1Internal Revenue Service. Topic No. 409 – Capital Gains and Losses Transferring the shares to a charity instead of selling them means you never realize the gain, so none of that tax applies.
You also claim a charitable deduction equal to the shares’ fair market value on the transfer date. That deduction offsets ordinary income taxed at rates up to 37%. So one gift reduces two different taxes.
The math is easier to see with numbers. Say you bought stock for $10,000 and it’s now worth $110,000. Sell first and donate cash: you owe up to $23,800 in federal tax on the $100,000 gain and hand the charity $86,200, which is also the size of your deduction. Transfer the shares directly: the charity receives the full $110,000, your deduction is $110,000, and your capital gains tax on the appreciation is zero. Both sides come out ahead, and the gap grows as the embedded gain grows.
What Qualifies for the Full Deduction
Three conditions have to line up for the full-fair-market-value treatment.
The first is the holding period. The shares must be long-term capital gain property, meaning you’ve held them more than one year on the date of the gift.1Internal Revenue Service. Topic No. 409 – Capital Gains and Losses Donate stock held one year or less and your deduction drops to your cost basis, which removes most of the advantage.2Office of the Law Revision Counsel. 26 USC 170 – Charitable, Etc., Contributions and Gifts – Section: (e)(1)(A)
The second is that the security has a readily determinable market value. Common stock, preferred stock, mutual funds, ETFs, and bonds traded on a recognized exchange all qualify. Closely held shares and restricted stock follow more complex rules and generally require a qualified appraisal.
The third is the recipient. The charity must be a public charity holding tax-exempt status under Section 501(c)(3) of the Internal Revenue Code.3Internal Revenue Service. Exemption Requirements – 501(c)(3) Organizations The IRS Tax Exempt Organization Search tool confirms status before you send anything. Gifts to individuals, political organizations, or groups without 501(c)(3) status generate no deduction.
Private foundations are a trap worth calling out. For most private non-operating foundations, the deduction for donated appreciated stock is cut back to your cost basis rather than fair market value.4Office of the Law Revision Counsel. 26 USC 170 – Charitable, Etc., Contributions and Gifts – Section: (e)(1)(B)(ii) A narrow exception exists for private operating foundations and certain pass-through foundations that distribute contributions quickly after year end, but most private foundations do not qualify.5Internal Revenue Service.

How the Shares Are Valued
For publicly traded stock, fair market value is the average of the highest and lowest quoted selling prices on the date the shares land in the charity’s account. If the day’s high is $52 and the low is $48, the deductible value is $50 per share.6Internal Revenue Service. Publication 561 – Determining the Value of Donated Property It isn’t the closing price, and it isn’t whatever the price happens to be when you sign the transfer instructions.
Mutual fund shares don’t trade intraday, so the valuation is the closing net asset value on the date the fund sponsor processes the transfer and you lose control of the shares.
Your cost basis has no role in the deduction calculation for long-term appreciated stock. It matters only as a measure of how much capital gains tax you sidestepped.
You Have to Itemize
The deduction only lowers your tax bill if you itemize on Schedule A. For 2026, the standard deduction is $16,100 for single filers and $32,200 for married couples filing jointly.7Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 If your itemized deductions don’t clear those figures, the stock gift’s deduction adds nothing to your income tax result. You’d still avoid the capital gains tax, but the deduction itself would go unused.
Starting in 2026, a new 0.5% AGI floor applies to charitable deductions for itemizers. Only the portion of your charitable giving that exceeds 0.5% of adjusted gross income counts toward the deduction. On $500,000 of AGI, the first $2,500 of giving is effectively nondeductible. A separate 2026 provision lets non-itemizers deduct up to $1,000 ($2,000 married filing jointly) for cash gifts to qualifying operating charities, but that write-off does not apply to stock donations or to contributions to donor-advised funds.
If you sit near the standard deduction threshold, bunching a large stock gift into a single year can push your itemized total well past it and make the strategy work decisively.
Annual Deduction Limits and Carryover
A large gift can outrun what you’re allowed to deduct in one year. Long-term appreciated capital gain property given to a public charity is capped at 30% of adjusted gross income. Anything above the cap isn’t lost. You carry the excess forward and deduct it over the next five tax years, subject to the same 30% ceiling each year.8Office of the Law Revision Counsel. 26 USC 170 – Charitable, Etc., Contributions and Gifts – Section: (b)(1)(C)(ii)
With $400,000 of AGI and a $200,000 stock gift, you deduct $120,000 in year one and carry $80,000 into later years, where it competes for room under the same 30% cap.
The Basis Election
You can elect to value your deduction at cost basis rather than fair market value, which raises your applicable AGI limit (generally to 50%).9Office of the Law Revision Counsel. 26 USC 170 – Charitable, Etc., Contributions and Gifts – Section: (b)(1)(C)(iii) For highly appreciated stock the trade is usually a bad one, because you give up more in deduction size than you gain in headroom. For lightly appreciated shares where a single-year deduction matters, the election is worth modeling with an advisor.
Don’t Donate Stock That Has Lost Value
The whole strategy assumes the shares are worth more than you paid. If they’re worth less, flip the order. Sell the shares first, claim the capital loss on your return, and donate the cash. The loss offsets other investment gains or up to $3,000 of ordinary income a year, with the remainder carrying forward indefinitely. Handing the depreciated shares directly to the charity limits your deduction to current market value and throws the loss away.
Making the Transfer
The mechanics require coordination between you, your brokerage, and the charity. Ask the charity for its brokerage details: firm name, account number, and DTC (Depository Trust Company) number, which routes electronic securities transfers.
Then tell your brokerage to make a transfer in kind of the specific shares to the charity’s account. Be explicit that you are transferring shares, not selling them. If the brokerage sells the stock first and wires cash, you’ve realized the gain, and there’s no way to undo the sale afterward. This is where most mistakes happen.
The date the shares arrive in the charity’s account is the gift date. That date sets the fair market value and the tax year for your deduction. Broker-to-broker transfers usually take three to five business days, so late-December instructions carry real risk. If the shares don’t hit the charity’s account by December 31, the deduction moves to the following tax year no matter when you initiated the transfer.
Documentation You Need
The paperwork rules are strict, and a missing piece can cost you the deduction.
For any single contribution of $250 or more, you need a contemporaneous written acknowledgment from the charity before you file your return. It must describe the property (though not assign it a value) and state whether the charity gave you anything in return. If nothing was provided, the letter has to say so.10Internal Revenue Service. Charitable Contributions – Written Acknowledgments
When your total non-cash charitable contributions for the year exceed $500, attach Form 8283 to your tax return.11Internal Revenue Service. About Form 8283, Noncash Charitable Contributions Publicly traded shares go in Section A, which asks for the stock name, transfer date, acquisition date, cost basis, and fair market value.
Publicly traded securities are exempt from the qualified appraisal requirement because market prices establish value objectively. Closely held stock and other non-publicly traded securities worth more than $5,000 do require a qualified appraisal and Section B of Form 8283.12Internal Revenue Service. Instructions for Form 8283 – Section: Section B
Keep the underlying records too: brokerage statements showing the original purchase date and price, the transfer confirmation, and the charity’s acknowledgment letter. The IRS can ask for substantiation years after you file, and reconstructing it later is much harder than saving it now.
When the Charity Can’t Take Stock Directly
Many smaller charities aren’t set up to receive securities. They may have no brokerage account or no one on staff to handle the transfer. A donor-advised fund solves that by sitting in the middle.
A DAF is a charitable account at a sponsoring public charity such as Fidelity Charitable, Schwab Charitable, or Vanguard Charitable. You contribute the appreciated stock to the DAF and claim the deduction in the contribution year, still subject to the 30% AGI limit. The DAF sells the shares tax-free inside its own account and lets you recommend grants to specific charities over time. The proceeds can be invested and grow tax-free while they sit in the account.
The DAF route is particularly useful when you want a large deduction in a high-income year but plan to distribute the money gradually. Two limits to keep in mind: contributions to a DAF are subject to the 30% cap that applies to all appreciated stock gifts to public charities, and the new 2026 non-itemizer cash deduction specifically excludes DAF contributions.
