IRC §170
Charitable Deduction Optimization
Strategic charitable giving can include donating appreciated assets (avoiding capital gains), bunching donations in alternating years, using Donor Advised Funds for flexibility, or Charitable Remainder Trusts for larger amounts.
One important gate: charitable deductions only reduce your taxes if your total itemized deductions exceed the standard deduction ($32,200 MFJ / $16,100 single in 2026). If you give $8,000/year to charity but your other itemized deductions are low, you may be taking the standard deduction anyway and getting zero additional tax benefit.
Bunching solves this by concentrating two or more years of giving into one calendar year so you clear the itemization threshold in Year 1, then take the standard deduction in Year 2 — same total dollars given, but only one year of real tax savings instead of zero.
Who this may apply to
- Make regular charitable contributions
- Have appreciated assets (stocks, real estate)
- Want tax deductions while supporting causes you care about
- Itemize deductions (or want to consider bunching)
Strategy connections
Works well with
- Donor Advised Fund (DAF): A donor-advised fund can support bunching and delayed grant recommendations.
- Tax-Loss Harvesting: Donating appreciated assets and realizing losses can be coordinated across a portfolio.
What could block this
- No qualifying charitable contribution
- Itemized deductions do not exceed the applicable standard deduction
- Contribution substantiation or appraisal requirements are not met
Important considerations
- You need a written acknowledgment letter from every charity for any donation of $250 or more — get this before you file
- Donating clothing or household items: must be in ‘good used condition or better.’ Value must be documented (photos and a reasonable estimate)
- Cash donations to non-501(c)(3) organizations (GoFundMe campaigns for individuals, political donations) are NOT deductible
