Donor Advised Funds (DAF): The Strategic “Bunching” Tool

By Team BMT Dec 31, 2025

💡 Executive Summary

  • Problem: Small annual donations often fall below the Standard Deduction threshold, resulting in $0 tax benefit.
  • Solution: “Bunch” 3-5 years of donations into a DAF in a single year to itemize heavily.
  • Result: You maximize the tax deduction today, but can distribute the funds to charities slowly over time.
⚠️ DON’T DONATE CASH
The golden rule of DAFs: Always donate appreciated stock/crypto. By donating the asset directly, you eliminate the Capital Gains Tax on the appreciation AND get a full fair-market-value income tax deduction.

Think of a DAF as a “Charitable Investment Account.” You get the tax receipt the moment the money hits the account. Inside, the funds grow tax-free, and you can grant them to your church, alma mater, or local non-profit whenever you wish.

🧐 Core Strategy: “Bunching”
Instead of giving $10k/year for 5 years (Standard Deduction applies each year, benefit lost), give $50k in Year 1 to a DAF. You itemize in Year 1 for a huge refund, then take the Standard Deduction in Years 2-5.

“A DAF separates the ‘tax event’ from the ‘charitable event.’ You secure the deduction when your income is high, and distribute the goodwill when the need is great.”
