Charitable giving creates tax deductions, but the details matter. Cash donations to public charities are deductible up to 60% of AGI. Appreciated stock donations avoid capital gains tax entirely and are deductible at fair market value (up to 30% of AGI). Donor-advised funds allow a large lump-sum deduction in a high-income year with grants distributed to charities over many years. For business owners with variable income, the timing and form of charitable contributions can produce significantly different tax outcomes.

✓Key takeaway

Charitable giving options and their tax treatment:

Cash donations:

Deductible as an itemized deduction (Schedule A)
Limit: 60% of AGI for public charities (30% for private foundations)
Only benefits taxpayers who itemize (total itemized must exceed $15,750 single / $31,500 MFJ)
Excess carries forward 5 years

Appreciated stock:

Deductible at fair market value (not cost basis)
NO capital gains tax on the appreciation
Limit: 30% of AGI
Must hold for more than 1 year
Most tax-efficient form of charitable giving

Donor-Advised Fund (DAF):

Contribute a lump sum to a DAF, take the full deduction in that year
Distribute grants from the DAF to charities over time
The DAF invests the balance (growth is tax-free)
Best for bunching donations into a high-income year

Bunching strategy: Instead of $10,000/year to charity (which falls below the standard deduction threshold), contribute $50,000 in one year to a DAF. The $50,000 pushes itemized deductions above the standard deduction, creating a tax benefit that wouldn’t exist with annual $10,000 donations.

How does the bunching strategy work?

Hypothetical example

Round numbers. A business owner (MFJ). Normal year AGI: $200,000. High year AGI: $400,000. Gives approximately $10,000/year to charity. Other itemized deductions: $18,000 (SALT $10,000 + mortgage interest $8,000).

Without bunching (donate $10,000/year): Total itemized: $18,000 + $10,000 = $28,000. Standard deduction: $31,500. Standard deduction wins. The $10,000 donation provides $0 additional tax benefit.

With bunching (contribute $50,000 to DAF in the high year): High year itemized: $18,000 + $50,000 = $68,000. Standard deduction: $31,500. Additional deduction over standard: $36,500. Tax savings at 32%: $36,500 x 32% = $11,680.

The owner distributes $10,000/year from the DAF over 5 years. Takes the standard deduction in the other 4 years.

5-year tax benefit comparison:

Without bunching: $0
With bunching: $11,680

Appreciated stock donation: Owner holds $50,000 of stock (basis $10,000, FMV $50,000). If sold and donated as cash:

Capital gains tax on $40,000 gain: $9,520
Net donated: $40,480

If donated directly to DAF:

No capital gains tax: $0
Full $50,000 deduction
Additional savings: $9,520 (avoided capital gains tax)
