What wording is required for tax deductions?

Include donor name, date of gift, amount or detailed noncash description, a statement about goods/services provided (if any), and the organization's EIN. This supports IRS substantiation for deductible gifts.

Do I need a signature on every letter?

A signature is not legally required for the IRS, but a signed letter increases donor confidence; signed or electronically authenticated acknowledgments are acceptable under ESIGN and UETA when retention and intent are documented.

Can I send acknowledgments electronically?

Yes. Electronic acknowledgments are legally valid under the ESIGN Act (15 U.S.C. ch. 96) and state UETA laws provided consent and retention requirements are met.

How soon should a donor receive a letter?

Issue acknowledgments promptly—best practice is within 48–72 hours for electronic gifts and within 7–14 days for mailed donations to support donor needs and tax recordkeeping.

What if the donor requests a corrected letter?

Prepare a corrected acknowledgment noting the amendment, date it, and record the change in your CRM and finance system to maintain an auditable trail.

Are noncash gifts treated differently?

Noncash gifts require a clear description of the property and condition; high-value property may require donor appraisal and additional disclosures per IRS rules; consult tax counsel for gifts over $5,000.

What a Letter of Thanks for Donations Is and When it’s Used

A Letter of Thanks for Donations is a written acknowledgment sent by a nonprofit, charity, or fundraiser to a donor confirming receipt of a gift and expressing appreciation. It documents the date, amount or description of noncash items, donor name, and any donor-restricted purpose. For U.S. tax purposes, letters often include whether goods or services were provided in return and a statement about deductible amounts.

Why Sending a Clear Thank-You Letter Matters

Acknowledgment letters support donor relations, meet IRS substantiation requirements for tax-deductible gifts, and create an auditable record of charitable contributions. Clear letters reduce donor inquiries and help the organization maintain consistent gift records.

Who Prepares and Who Receives These Letters

Use a standardized template for consistency, and personalize when appropriate to strengthen donor stewardship and legal compliance.

Development Director — Prepares standardized letters and ensures IRS substantiation language is included for deductible gifts.
Finance Manager — Verifies gift amount, date, and fund designation before the letter is issued.
Donor Relations Coordinator — Personalizes messages, records donor preferences, and routes letters to CRM.
