Donating appreciated long-term capital gain property to a qualified charity is one of the most tax-efficient strategies available to business owners. Under IRC 170, the donor deducts the full fair market value of the donated property (not the cost basis) and pays zero capital gains tax on the appreciation. This creates a double benefit that donating cash cannot match. The strategy works with publicly traded stock, closely held business interests (with a qualified appraisal), real estate, and other capital gain property held for more than one year. The deduction for appreciated capital gain property is limited to 30% of adjusted gross income (vs. 60% for cash donations), but unused amounts carry forward for up to 5 years. For business owners with large unrealized gains who are also charitably inclined, this strategy can save tens of thousands of dollars compared to selling the asset, paying the capital gains tax, and donating the after-tax proceeds.

✓Key takeaway

Charitable contribution deduction limits (2025):

Donation Type	AGI Limit	Carryforward
Cash to public charity (50% limit org)	60% of AGI	5 years
Appreciated LTCG property to public charity	30% of AGI	5 years
Cash to private foundation	30% of AGI	5 years
Appreciated LTCG property to private foundation	20% of AGI (and deduction limited to cost basis for most property)	5 years
Cash or property to donor-advised fund (DAF)	Same as public charity (60% cash / 30% appreciated)	5 years

Donating appreciated stock vs. cash vs. selling first:

Strategy	Deduction	Capital Gains Tax Paid	Net Tax Benefit
Donate $100,000 of appreciated stock (basis $20,000)	$100,000	$0	Deduction + CG avoidance
Donate $100,000 cash	$100,000	N/A	Deduction only
Sell stock ($80,000 gain), donate $100,000 cash	$100,000	$12,000-$18,800 (15-23.8% on $80K)	Deduction minus CG tax paid

Requirements for the full FMV deduction:

Requirement	Details
Holding period	Must hold the property more than 1 year (long-term)
Type of charity	Public charity or DAF (30% AGI limit)
Appraisal	Required for non-publicly-traded property over $5,000
Form 8283	Required for non-cash contributions over $500
Short-term property	Deduction limited to cost basis (no benefit from appreciation)

How does donating stock beat donating cash?

Hypothetical example

Round numbers. A business owner. MFJ. AGI: $500,000. Wants to donate $50,000 to charity. Owns stock purchased 5 years ago for $10,000, now worth $50,000 ($40,000 unrealized long-term capital gain).

Option A: Sell the stock, donate the cash

Step	Amount
Sell stock for $50,000
Long-term capital gain	$40,000
Federal LTCG tax (20%)	$8,000
NIIT (3.8%)	$1,520
State tax (~5%)	$2,000
Total tax on sale	$11,520
Cash available to donate	$50,000 (donate the full amount, pay tax from other funds)
Charitable deduction	$50,000
Tax savings from deduction (35% bracket)	$17,500
Net tax benefit	$17,500 - $11,520 = $5,980

Option B: Donate the stock directly

Step	Amount
Donate stock to charity (FMV $50,000)
Capital gains tax	$0 (no sale, no gain recognized)
Charitable deduction	$50,000 (full FMV)
Tax savings from deduction (35% bracket)	$17,500
Net tax benefit	$17,500

Comparison:

Metric	Sell & Donate Cash	Donate Stock Directly
Charity receives	$50,000	$50,000
Capital gains tax paid	$11,520	$0
Deduction amount	$50,000	$50,000
Tax savings from deduction	$17,500	$17,500
Net tax benefit to donor	$5,980	$17,500
Additional savings from donating stock		$11,520

Donating the stock directly saves $11,520 in capital gains taxes that would have been owed on the sale, while providing the identical $50,000 charitable deduction.

The basis reset strategy: After donating the $50,000 of appreciated stock, the business owner uses $50,000 of cash to buy replacement stock in the same company (or a similar investment).

Before	After
Stock: $50,000 FMV, $10,000 basis	Stock: $50,000 FMV, $50,000 basis (reset)
Cash: $50,000	Cash: $0
Unrealized gain: $40,000	Unrealized gain: $0

The wash sale rules (IRC 1091) don’t apply to charitable donations (they only apply to sales at a loss). The donor can buy replacement stock immediately after donating.

Donor-advised fund (DAF) strategy: Instead of donating directly to a single charity, the business owner donates the $50,000 of stock to a donor-advised fund (Fidelity Charitable, Schwab Charitable, Vanguard Charitable).

Advantage	Details
Immediate deduction	Full $50,000 deduction in the year of contribution
Grant over time	Recommend grants to charities over multiple years
No capital gains	Stock is sold inside the DAF (tax-exempt entity)
Bunching strategy	Donate 2+ years of giving in one year, take standard deduction in off years
Investment growth	Funds grow tax-free inside the DAF

Bunching example:

Year	Without Bunching	With DAF Bunching
2025	$20,000 donation, itemize ($20,000 > $31,500 SD? No, take SD)	$100,000 stock donation to DAF, itemize ($100,000)
2026	$20,000 donation, take SD ($31,500)	DAF grants $20,000, take SD ($31,500)
2027	$20,000 donation, take SD ($31,500)	DAF grants $20,000, take SD ($31,500)
2028	$20,000 donation, take SD ($31,500)	DAF grants $20,000, take SD ($31,500)
2029	$20,000 donation, take SD ($31,500)	DAF grants $20,000, take SD ($31,500)
5-year deductions	$157,500 (SD each year)	$100,000 + $126,000 (4 years SD) = $226,000

Bunching creates $68,500 more in total deductions over 5 years, plus the capital gains avoidance on the appreciated stock.

AGI limitation planning:

AGI	30% Limit (Appreciated Property)	Max Deduction This Year	Carryforward
$200,000	$60,000	$50,000 (full amount)	$0
$500,000	$150,000	$50,000 (full amount)	$0
$100,000	$30,000	$30,000	$20,000 (carried forward up to 5 years)

For owners with AGI high enough to absorb the 30% limit, the full deduction is taken in one year. For those with lower AGI relative to the donation, the carryforward ensures the full deduction is eventually claimed.

What are the deduction limits for charitable contributions by businesses?

C-Corporations can deduct charitable contributions up to 10% of taxable income (computed before the deduction, NOL carrybacks, and certain other items), with excess contributions carried forward for 5 years. Sole proprietors, partners, and S-Corp shareholders deduct charitable contributions on their personal returns, subject to limits based on the type of property donated and the type of recipient: cash to public charities is limited to 60% of AGI, appreciated capital gain property to public charities is limited to 30% of AGI, and contributions to private foundations face lower limits. Donating appreciated property held more than one year (such as stock) lets you deduct the full fair market value while avoiding the capital gains tax you would owe if you sold it first. A donor-advised fund lets you bunch multiple years of charitable giving into a single tax year to exceed the standard deduction threshold, then recommend grants from the fund over time.
