Donating Appreciated Stock Is One of the Most Tax Efficient Charitable Gifts
Donating long‑term appreciated stock (publicly traded shares held more than one year) to a qualified charity is a high‑impact way for donors to support causes while obtaining favorable tax treatment. Compared with selling the stock and donating the cash, an in‑kind stock gift typically gives the donor a larger tax deduction and avoids capital gains tax on the built‑in appreciation.
The Core Tax Benefits:
Full fair‑market‑value (FMV) deduction: If the stock would have produced long‑term capital gain if sold, a donor who gives the shares to a qualified public charity generally can deduct the FMV of the donated shares on the date of the gift (subject to AGI limits and provided the donor itemizes deductions).
Avoidance of capital gains tax: Because the charity receives the stock tax‑free, it can sell the shares without the donor recognizing the built‑in gain—so the donor avoids the capital gains tax that would apply on a sale.
Greater effective gift to charity: Avoiding tax on the appreciation means a larger amount reaches the charity compared with donating net proceeds after selling the stock.
Potential state tax and AMT advantages: In many cases the state income tax and federal surtaxes that would apply to a sale are also avoided, improving after‑tax efficiency (check state rules).
AGI Limits and the “Basis vs. FMV” Election
FMV Deduction AGI limit: Deductions for long‑term appreciated property gifted to public charities are generally limited to a percentage of the donor’s AGI—so the FMV deduction is subject to a lower contribution limitation category (commonly 30% of AGI for the applicable charity type).
Electing Basis Instead of FMV: A donor may elect to take a deduction equal to the stock’s basis (generally cost) rather than FMV; doing so moves the contribution into a higher AGI limitation category (often 50% of AGI), but it sacrifices the larger FMV deduction. This election can make sense when the donor cannot use the 30% of AGI bucket and would rather deduct something now than carry unused amounts forward.
Carryforward Rules: Excess charitable deductions that cannot be used because of AGI limits may be carried forward for up to five years.
Determining Fair Market Value: For publicly traded stocks, the Fair Market Value (FMV) is determined by the average of the highest and lowest quoted selling prices on the date the donation is officially completed. This "valuation date" is generally the day the stock transfer reaches the charity's account or the postmark date if physical certificates are mailed. How the Calculation Works:
Active Markets: You add the day's high and low prices (not necessarily the opening and closing quotes) together and divide by two. For example, if a share's high was $11 and its low was $9, the FMV used for your deduction is $10.
No Sales on Donation Date: If the market was closed or the stock didn't trade that day, the FMV is a weighted average of the high and low prices from the nearest trading dates before and after your donation.
Multiple Exchanges: If the stock is listed on more than one exchange, you must use the prices from the exchange where it is primarily traded.
When FMV is Not Allowed: Not all property receives the FMV treatment. If the donated property would not produce long‑term capital gain if sold—for example, short‑term holdings or property that would generate ordinary income—the deductible amount is generally limited to the donor’s basis in the asset, not FMV. This rule applies broadly to property that would produce ordinary income on sale.
Practical Tax Planning Tips for Donors:
Give Long‑term, Publicly Traded Securities In‑kind: Donors should transfer the shares directly from their brokerage account to the charity’s broker to avoid a constructive sale and to preserve the FMV deduction. Document the transfer date and the number of shares.
Confirm Recipient Status: Verify the donee is a qualified 501(c)(3) public charity to secure the FMV deduction. This can be done via the IRS website to search for an organization's tax-exempt status.
Contemporaneous Written Acknowledgment (CWA): For any contribution of $250 or more get the CWA from the charity; for noncash gifts of significant size follow Form 8283 instructions and appraisal rules where required.
Consider Bunching Gifts or Donor‑Advised Funds (DAFs): A donor could use a DAF, which lets them take the deduction in the year of the gift while a payout to a qualified charity can occur later.
Run the Numbers: Compare the tax and cash outcomes of (A) giving the stock directly, (B) selling the stock and donating the after‑tax cash, and (C) electing basis instead of FMV when applicable. Factors to include: long‑term capital gains rate, donor’s marginal tax rate, state tax, AMT implications, and how much of the deduction the donor can use in the current year.
A Simple Numeric Illustration: Assume stock with FMV $100,000 and basis $10,000 (held over 1 year…long term).
Donate the Stock Directly: donor may deduct $100,000 (subject to AGI limits) and avoids tax on the $90,000 unrealized gain.
Sell Then Donate: selling triggers tax on the $90,000 gain; at a 15% LTCG tax rate the tax is $13,500, leaving $86,500 to donate—so the deductible gift is smaller and the donor has paid tax unnecessarily on the appreciation.
Alternatives and Related Strategies:
Gifting appreciated stock to a low‑income relative or parent who can use the zero‑rate capital gains bracket may be an effective way to pass value with minimal tax—this is an alternative to charitable giving in family support scenarios and requires careful planning to avoid adverse impacts on the recipient’s benefits. The donor who gifts stock to an individual is not entitled to a tax deduction for the gift.
Donor‑advised funds and private foundations follow the same general donation rules for appreciated securities, but different AGI limits and administrative considerations may influence the best vehicle.
Common Pitfalls to Watch For:
Donating short‑term or ordinary‑income property expecting an FMV deduction—donors instead get a deduction limited to basis.
Failing to verify the selected charity’s status or properly documenting the transfer, can jeopardize the deduction.
Overlooking the donor’s AGI limitations and the option to elect basis when that election better fits the donor’s tax situation.
Conclusion: For most donors holding long‑term appreciated publicly traded stock, an in‑kind donation to a qualified charity provides a twofold tax benefit: a charitable deduction based on FMV (subject to AGI limits) and elimination of capital gains tax on the appreciation—resulting in a larger, more tax‑efficient gift.
