Charitable giving creates tax benefits, but the way the deduction works depends on the business entity type. C-Corps can deduct charitable contributions as a business expense (up to 10% of taxable income). Pass-through entities (S-Corps, partnerships, sole proprietorships) pass the contribution through to the owner’s personal return as an itemized deduction. This distinction matters because many small business owners take the standard deduction and wouldn’t benefit from additional itemized deductions without strategic planning.

✓Key takeaway

Charitable deduction rules by entity type:

C-Corp:

The C-Corp deducts charitable contributions on its corporate return
Limited to 10% of taxable income (before the charitable deduction and certain other items)
Excess contributions carry forward 5 years
Cash, property, and inventory donations qualify

S-Corp / Partnership / Sole Proprietorship:

Charitable contributions pass through to the owner’s personal return
Deductible only as an ITEMIZED deduction (Schedule A)
If the owner takes the standard deduction ($15,750 single, $31,500 MFJ in 2025), the charitable deduction provides NO benefit
Cash contributions: limited to 60% of AGI
Appreciated property: limited to 30% of AGI
Excess carries forward 5 years

Strategies for pass-through owners who take the standard deduction:

1. Bunching contributions (donor-advised fund). Instead of donating $5,000/year (which does not push total itemized deductions above the standard deduction), contribute $25,000 to a donor-advised fund (DAF) in one year. The $25,000 contribution is deductible in the year of the gift, potentially pushing total itemized deductions above the standard deduction threshold. The DAF distributes the money to charities over the next 5 years. Take the standard deduction in the other 4 years. For owners with variable income, time the lump-sum contribution to the highest-income year for the largest marginal tax benefit (a $50,000 contribution at a 32% marginal rate saves more than the same contribution at 24%).

2. Donating appreciated property. Donate stock, real estate, or other appreciated property instead of cash. The deduction is the fair market value of the property, and the donor avoids capital gains tax on the appreciation. Limit: 30% of AGI for appreciated property held over 1 year.

3. Qualified charitable distribution (QCD) for owners over 70.5. Owners over 70.5 can distribute up to $105,000 from an IRA directly to a charity. The distribution is excluded from income (not a deduction, but the effect is the same). This works even if the owner takes the standard deduction.

4. Conservation easement. Business owners who hold real property (farmland, undeveloped land) can donate a conservation easement. The deduction can be substantial (the difference between the property’s FMV and its restricted value). Syndicated conservation easements are under IRS scrutiny, but legitimate easements on property the owner actually uses remain valid.

How does bunching with a donor-advised fund work?

Hypothetical example

Round numbers. For current guidance, see IRS charitable contribution deductions. An S-Corp owner (MFJ). AGI: $200,000. Normally donates $5,000/year to charity. Mortgage interest: $8,000. State/local taxes: $10,000 (capped at SALT limit). Total itemized deductions without charitable: $18,000.

Without bunching (every year):

Itemized deductions: $18,000 + $5,000 charity = $23,000
Standard deduction: $31,500
The owner takes the standard deduction every year
Charitable deduction benefit: $0 (the standard deduction is higher)

With bunching (every 5 years): Year 1 (bunching year):

Contribute $25,000 to a donor-advised fund (5 years of $5,000 donations)
Itemized deductions: $18,000 + $25,000 = $43,000
Standard deduction: $31,500
Benefit of itemizing: $43,000 - $31,500 = $11,500 in additional deduction
Tax savings: $11,500 x 24% = $2,760

Years 2-5:

Direct the DAF to distribute $5,000/year to chosen charities
Take the standard deduction ($31,500) each year
No additional tax benefit from the distributions (the deduction was taken in Year 1)

5-year comparison:

Without bunching: $0 charitable tax benefit (standard deduction every year)
With bunching: $2,760 tax savings in the bunching year
Same total charitable giving: $25,000 over 5 years

Donating appreciated stock instead of cash: If the owner donates $25,000 of stock (purchased for $10,000, now worth $25,000):

Deduction: $25,000 (FMV of the stock)
Capital gains avoided: ($25,000 - $10,000) x 15% = $2,250
Tax savings: $2,760 (income tax) + $2,250 (avoided capital gains) = $5,010
The owner then uses $25,000 cash (that would have been donated) to repurchase similar stock, resetting the basis to $25,000

DAF logistics:

Open a donor-advised fund at Fidelity Charitable, Schwab Charitable, or Vanguard Charitable (minimum initial contribution: $5,000-$25,000)
Contribute cash or appreciated assets
Recommend grants to qualified charities over time
The DAF handles the documentation and 8283 forms
Annual DAF fees: typically 0.60% of the balance ($150/year on a $25,000 balance)

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.
