Here are five ways to elevate your donor acknowledgment

1. Know the IRS Thresholds

Any single contribution of $250 or more requires a written acknowledgment from your organization before the donor can claim a tax deduction. The letter must include:

  • Your organization’s name
  • The amount of cash contributed, or a description of non-cash items donated
  • A statement on whether goods or services were provided in exchange, and if so, a good-faith estimate of their value
  • For quid pro quo contributions over $75 (where the donor receives something of value, like a gala dinner), you’re required to provide a disclosure statement at the time of solicitation, not just at year-end.

2. Timing Matters

Donors need their acknowledgment letters in hand by the time they file taxes, but best practice is to send acknowledgments within 48–72 hours of receiving a gift. Prompt acknowledgment also significantly boosts donor retention and sets a professional tone heading into fall campaigns.

3. Don’t Wait Until December for Annual Summaries

Many organizations send a single annual giving summary in January. Consider sending a mid-year giving summary in July or August. This helps donors track their giving, catches any recording errors early (while they’re easy to fix), and re-engages supporters before your fall appeal lands in their inbox.

4. Audit Your Acknowledgement Templates Now

Before fall campaigns ramp up volume, review your letter templates for:

  • Accurate organizational information (legal name, EIN, address)
  • Correct language for non-cash and stock gifts
  • Proper handling of recurring/monthly donors (each payment technically needs acknowledgment, though an annual summary can satisfy this if structured correctly)
  • Sponsorship and event-related gifts with goods/services disclosures

5. Coordinate Acknowledgment with Your Books

Acknowledgment letters and your financial records should match — the amounts recorded as contribution revenue should tie directly to what’s reflected in donor letters. Discrepancies here are a common audit flag and a source of donor confusion if a donor’s letter doesn’t match their own giving records.
