Donor-Advised Funds and Charitable Bunching
A donor-advised fund (DAF) is a charitable giving vehicle administered by a sponsoring organization (typically a financial institution or community foundation) into which a donor makes an irrevocable contribution, receives an immediate tax deduction, and then recommends grants to qualified charities over time. The DAF allows two powerful planning strategies: bunching and appreciated asset gifting.
Bunching concentrates multiple years' worth of charitable contributions into a single year to exceed the standard deduction threshold, enabling itemized deduction in that year. A taxpayer who gives $10,000 per year to charity and has $25,000 in other deductions might take the $27,700 standard deduction (2023 MFJ) every year, receiving no tax benefit for their charitable giving. Instead, they could contribute $50,000 to a DAF in year one (claiming a $75,700 itemized deduction and a $48,000 tax benefit over the standard deduction), then distribute $10,000 from the DAF to their usual charities for five years — maintaining their giving pattern while maximizing the tax benefit.
Appreciated stock gifting to a DAF is often more tax-efficient than cash giving for donors holding appreciated securities. Contributing appreciated stock directly to a DAF avoids the capital gains tax that would apply on a sale, and the full fair market value is deductible (up to 30% of AGI for capital gain property). The math: a donor with $100,000 in stock with a $20,000 basis faces a $12,000 capital gains tax on a sale ($80,000 gain × 15%), netting only $88,000 to give. Contributing the stock directly to a DAF provides a $100,000 deduction with no capital gains tax — $12,000 better. The DAF then sells the stock internally (tax-free as a charity) and invests the proceeds for future grantmaking.
