A capital donation tax deduction lets you give appreciated property to a qualified charity, deduct its full fair market value, and avoid the capital gains tax you would have paid on a sale. For long-term appreciated property given to a public charity, the deduction is capped at 30% of your adjusted gross income each year, and anything above that carries forward for up to five more years. You have to itemize on Schedule A to claim it, so the strategy pays off when your total itemized deductions clear the standard deduction.
What Counts as Appreciated Property
The deduction hinges on one word: long-term. You must have owned the asset for more than a year before donating it. Give away something you’ve held for a year or less and the tax code treats it as ordinary income property, with a much smaller deduction.
The assets that fit the rule most cleanly are publicly traded stock and mutual fund shares, real estate, artwork and collectibles, and interests in closely held businesses. Appreciated stock is the workhorse. The price is objective, no appraisal is required, and the donor avoids capital gains tax on years of growth in a single move.
The recipient has to be an organization qualified under Section 170 of the Internal Revenue Code.1Office of the Law Revision Counsel. 26 USC 170 – Charitable, Etc., Contributions and Gifts The most generous limits apply to public charities: churches, hospitals, universities, and groups that draw substantial support from the general public or government. Donor-advised funds held by public charities qualify at the public charity level. Private non-operating foundations qualify too, but with tighter caps and, for appreciated property, a reduced deduction amount.
AGI Limits by Gift and Recipient
Your deduction is capped as a percentage of AGI, and the percentage depends on both what you give and who receives it. The limits stack separately, so if you donate cash and appreciated stock in the same year, each category has its own ceiling.
- Cash to a public charity: up to 60% of AGI.
- Appreciated long-term capital gain property to a public charity: up to 30% of AGI, deducted at full fair market value.
- Cash to a private non-operating foundation: up to 30% of AGI.
- Appreciated capital gain property to a private non-operating foundation: up to 20% of AGI, with the deduction generally reduced to cost basis rather than fair market value.
These caps come from Section 170(b)(1).1Office of the Law Revision Counsel. 26 USC 170 – Charitable, Etc., Contributions and Gifts
The 50% Election
You can choose to reduce your deduction on appreciated capital gain property to its cost basis instead of its fair market value. Doing so raises the AGI ceiling from 30% to 50%. You lose the deduction for the appreciation, but you can absorb more of your income in the current year. The election is all-or-nothing for the year: it applies to every piece of capital gain property you donate during that tax year, not just one gift.2eCFR. 26 CFR 1.170A-8 – Limitations on Charitable Deductions by Individuals
For most donors sitting on a large unrealized gain, keeping the 30% ceiling at full fair market value produces a better outcome. The election tends to help when the appreciation is small or when other planning reasons make a bigger current-year write-off more valuable.
Five-Year Carryforward
When your donation exceeds the applicable AGI limit, the excess doesn’t disappear. It carries forward for up to five additional tax years and stays subject to the same percentage limit that applied originally. Anything still unused after that five-year window expires.1Office of the Law Revision Counsel. 26 USC 170 – Charitable, Etc., Contributions and Gifts
When the Deduction Drops to Basis
Not every donation earns a full fair-market-value deduction. Section 170(e)(1)(A) requires you to subtract the portion of gain that would not have been long-term capital gain if you’d sold the asset.1Office of the Law Revision Counsel. 26 USC 170 – Charitable, Etc., Contributions and Gifts The practical result is a deduction capped at your cost basis for a few categories.
Ordinary income property is the clearest case. Anything you’ve held a year or less, inventory, or property whose sale would produce ordinary income all fall here. Short-term capital gain property does too.
Depreciable business property is trickier. Gain attributable to Section 1245 depreciation recapture is treated as ordinary income, which pushes the deduction for most depreciable personal property down to basis. Real estate under Section 1250 generally doesn’t face the same reduction, so an appreciated commercial building can still produce a full fair-market-value deduction for the capital gain portion.
Appreciated property given to a private non-operating foundation is the third case. The deduction is generally reduced to cost basis. One notable exception: publicly traded stock donated to a private non-operating foundation is still deductible at full fair market value, though the 20% AGI limit still applies.
How Fair Market Value Is Set
Fair market value is the price a willing buyer would pay a willing seller when neither is under pressure and both know the relevant facts.3Internal Revenue Service. Publication 561 – Determining the Value of Donated Property For publicly traded stock, FMV is the average of the highest and lowest quoted selling prices on the date you make the gift. For real estate, art, closely held business interests, and other non-publicly-traded assets, the valuation is softer and usually requires a qualified appraisal.
The IRS looks at original cost, sales of comparable property, replacement cost adjusted for depreciation and obsolescence, and expert opinions. Values that look inflated against those benchmarks draw attention, and the penalties are steep.
When You Need a Qualified Appraisal
If your claimed deduction for a single item, or a group of similar items, tops $5,000, you need a qualified appraisal and must complete Section B of Form 8283.4Internal Revenue Service. Form 8283 – Noncash Charitable Contributions Publicly traded securities over $5,000 are the main exception. Vehicles, intellectual property, and certain inventory report on Section A under separate rules regardless of value.
A qualified appraisal must come from an independent appraiser with credentials to value that specific type of property. Not the donor, not the charity, not a relative of either. The report has to be signed and dated no earlier than 60 days before the contribution and no later than the due date, including extensions, of the return where you first claim the deduction.5eCFR. 26 CFR 1.170A-17 – Qualified Appraisal and Qualified Appraiser
Both the appraiser and the charity have to sign Section B of Form 8283. The appraiser acknowledges the penalties for overstating value; the charity acknowledges receipt. Missing signatures or a late appraisal can wipe out the deduction entirely, and the IRS does not treat those as technical formalities.
Paperwork You Need to Keep the Deduction
Documentation is layered. Miss a step and the deduction can vanish even if the underlying gift was legitimate.
Written Acknowledgment at $250
Any single contribution of $250 or more requires a contemporaneous written acknowledgment from the charity. It has to describe the property (not value it), state whether you got anything in return, and estimate the value of any such benefit. Anything you received in exchange reduces your deduction. You need the acknowledgment in hand by the earlier of the date you file or the return’s due date including extensions.6Internal Revenue Service. Charitable Contributions – Written Acknowledgments
Form 8283 Above $500
Any non-cash donation with a total deduction above $500 requires Form 8283 attached to your return. Section A covers gifts between $500 and $5,000, plus publicly traded securities, vehicles, and certain inventory at any value. Section B covers everything else above $5,000 and requires the qualified appraisal and signatures.7Internal Revenue Service. Instructions for Form 8283 – Noncash Charitable Contributions
Form 8282 If the Charity Sells
If the charity sells, exchanges, or otherwise disposes of your donated property within three years, it must file Form 8282 and send you a copy. The requirement doesn’t apply if the property was valued at $500 or less or if the charity distributed it for charitable purposes.8Internal Revenue Service. Charitable Organizations – Substantiating Noncash Contributions The form reports the gross sale proceeds, which the IRS compares to your claimed deduction. A wide gap is one of the more common audit triggers on non-cash gifts.
Special Rules for Vehicles, Art, and Fractional Interests
A few categories have rules that override the general framework, and each can catch donors off guard.
Vehicles worth more than $500 are the biggest gotcha. If the charity sells the car, boat, or airplane without significant intervening use or material improvement, your deduction is limited to the gross sale proceeds, not blue-book value. The charity must send you a Form 1098-C within 30 days of the sale or disposition.9Internal Revenue Service. About Form 1098-C, Contributions of Motor Vehicles, Boats, and Airplanes Full FMV is available only when the charity actually uses the vehicle in its programs or makes material improvements before selling.
Art donations follow the general appraisal rules, but the IRS applies extra scrutiny. The Commissioner’s Art Advisory Panel reviews artwork appraisals generally valued above $150,000, and the IRS has discretion to review below that too.10Internal Revenue Service. Art Appraisal Services For high-value pieces, a credible appraisal from a recognized specialist in that type of art matters a great deal.
Fractional interests in tangible personal property (a share of a painting or sculpture, for instance) can be donated, and you deduct the value of the fraction. The trap is on the back end. You must donate all remaining interests to the same charity by the earlier of 10 years from the initial gift or your death, and the charity must take substantial physical possession and use the property for its exempt purpose during that period. Miss the deadline and the IRS recaptures every previously claimed deduction, adds interest, and tacks on an additional tax of 10% of the recaptured amount.1Office of the Law Revision Counsel. 26 USC 170 – Charitable, Etc., Contributions and Gifts
Donor-advised funds sit inside the ordinary rules but deserve a mention because they’re the simplest planned giving tool. A DAF is held by a sponsoring public charity, so an appreciated-security gift qualifies for the 30% AGI limit at full fair market value. You get the deduction in the year of the contribution and recommend grants to operating charities over time. Charitable remainder trusts and charitable lead trusts offer more elaborate structures for donors who want income streams or estate tax planning alongside the charitable deduction, and each has its own filing and drafting requirements.
Penalties for Overstated Values
Inflated appraisals carry real cost. A substantial valuation misstatement triggers a 20% accuracy-related penalty on the underpaid tax; a gross misstatement doubles the penalty to 40%.11Internal Revenue Service. The Section 6662(e) Substantial and Gross Valuation Misstatement Penalty A separate penalty under Section 6662(l) can reach 50% of the underpayment attributable to an overstated charitable deduction.12Office of the Law Revision Counsel. 26 USC 6662 – Imposition of Accuracy-Related Penalty on Underpayments
Appraisers face their own exposure under Section 6695A. An appraiser who knew or should have known the appraisal would be used on a return, and whose valuation causes a substantial or gross misstatement, can be penalized directly.13Internal Revenue Service. Penalties Applicable to Incorrect Appraisals Reputable appraisers respond by staying conservative, and any appraiser promising an unusually high number is a warning sign.
For individuals, penalties apply once the underpayment attributable to valuation misstatements exceeds $5,000. For corporations, the floor is $10,000. Those thresholds sound comfortable until you remember that one overstated real estate parcel or piece of art can clear them without much trouble.
