DAF Bunching Strategy

Contribute 2 years of donations ($10,000) to a Donor-Advised Fund in year 1. Take standard deduction in year 2. Grant from the DAF whenever you choose.

Extra federal tax savings vs spreading annually: +$3,784

Qualified Charitable Distribution (QCD) — Age 70½+

If you’re 70½ or older, you can transfer up to $105,000 directly from your IRA to a charity. The QCD counts toward your Required Minimum Distribution and is excluded from taxable income entirely — worth more than a deduction for most retirees, even if you don’t itemize.

Cash Donation AGI Limit (IRC §170(b)(1)(G))

= $72,000

Cash donations to public charities are deductible up to 60% of AGI. Excess carries forward 5 years. Donations to private foundations: 30% limit.

Cash Deductible Amount

= $5,000

All cash donations fall within the AGI limit

Stock Donation — AGI Limit

= $36,000

Appreciated property (stocks, real estate) donated to public charities: 30% of AGI limit. You deduct the full FMV — not the cost basis.

Capital Gains Avoided

= $0

By donating appreciated stock instead of selling it, you avoid paying capital gains tax on the appreciation. This is often worth more than the deduction itself.

Total Charitable Deduction

= $5,000

Deductible: $5,000 cash + $0 non-cash + $0 stock

Total Itemized vs Standard Deduction

= $17,000 vs $14,600 standard

Itemizing saves $2,400 over the standard deduction

Federal Tax Savings

= $528

Tax savings from itemizing over the standard deduction, at your marginal rate. Only the amount ABOVE the standard deduction generates a benefit.

State Tax Savings

= $120

Many states allow itemized deductions that mirror federal. Combined federal + state savings reduces your effective cost of giving.

Effective Cost of Giving

= $4,352

You donate $5,000 but it only costs you $4,352 after tax savings — a 0.1% discount on your generosity.

DAF Bunching Strategy

= +$3,784 extra savings

By contributing $10,000 to a DAF in year 1 and $0 in year 2, you clear the standard deduction hurdle and save $3,784 more in federal tax than spreading evenly.

QCD Limit (2024)

= $105,000

A Qualified Charitable Distribution from your IRA counts toward your RMD, reduces taxable income (even without itemizing), and can be worth far more than a deduction for retirees in high brackets.
