How to write a donation acknowledgment letter

A donation acknowledgment letter is a nonprofit's written record of a gift. In the US, a donor can't deduct any single gift of $250 or more without one. It names your organization and states the amount of cash, or describes donated property without valuing it. It also says whether the donor got anything in return and, if so, describes it with a good faith estimate of its value.

One letter can't cover every gift. A $50 online gift, a gala ticket, a donated ultrasound machine and a donor-advised fund grant each need different sentences.

What a donation acknowledgment letter must say

IRS Publication 1771 lists what a written acknowledgment must contain1. Skipping one carries no IRS penalty, but it costs the donor the deduction. For any single gift of $250 or more, include:

  • Your organization's name
  • The amount of any cash gift
  • A description, but not the value, of any property
  • A statement that you gave nothing in return, if that's true
  • Otherwise, a description and good faith estimate of the value of what you gave
  • For a religious organization, a statement if all you gave was intangible religious benefits

Gifts under $250 don't need the formal letter, and separate gifts aren't added together. Send a dated receipt anyway. Without a bank or card record, a donor needs one showing your name, the date and the amount to deduct a cash gift. From 2026, people who don't itemize can deduct up to $1,000 of cash gifts, or $2,000 on a joint return2, so more donors may need one.

There's no IRS form. A letter, postcard, email or computer-generated receipt all count, and one annual summary can cover several gifts.

Match the wording to the gift

Before drafting, sort every gift on four facts: its form, what the donor got back, the size of that single gift and who legally gave it. Sort by amount alone and a $150 gala ticket gets the standard letter, which wrongly says the guest got nothing.

What each gift needs

GiftThe letter statesLeave out
Cash, nothing given backThe amount, the date and that no goods or services were providedThe donor's Social Security number
Ticket, auction win or thank-you giftThe payment, what the donor got, its estimated value and the differenceCalling the whole payment a gift
Donated goodsHow many, what they are and their conditionAny dollar value
Publicly traded stockNumber of shares, the company and the date receivedA dollar value
Volunteer's unreimbursed costsThe services given, and whether anything came backAny dollar amount
Donor-advised fund grantAddressed to the fund's sponsor, naming the advisorReceipt wording for the advisor

A donor-advised fund grant is the sponsor's gift, not the advisor's. The advisor's tax deduction, if any, came when they gave to the fund, backed by the sponsor's acknowledgment of its exclusive legal control3.

Work out what's deductible at events

When a donor pays more than $75 and gets something back, such as a dinner, an auction lot or a thank-you gift, you owe them a written disclosure. It must say that only the part of the payment above the benefit's value is deductible, and estimate that value in good faith4.

Put it in the request, such as the invitation, an annual appeal reply card or a sponsorship proposal offering a table, or in the acknowledgment. Publication 1771 warns that small print within a larger document might not count1. Unlike a missing acknowledgment, a missing disclosure carries a penalty of $10 per contribution, up to $5,000 per event or mailing.

Value the benefit at what it would cost to buy. In the IRS's own example, an hour with a tennis pro who charges $100 is worth $1004, even to a donor who paid $500. A museum tour that's normally free is worth $0, even when a well-known artist leads it.

Auctions work lot by lot. In Publication 5263, a bidder who pays $600 for a week at a beach house, no more than its fair rental value, hasn't made a deductible gift. When a lot sells at or below its value, say plainly that no part of the payment is deductible.

ExampleA gala ticket acknowledgmentAn illustrative example written for this guide. The charity and figures are made up.

Dear Marguerite,

Thank you for joining us at the Harvest Table dinner on November 8. Cedar Line Community Health received your payment of $150 for one ticket.

In return, you received dinner and drinks with an estimated fair market value of $58. The amount of your payment that is deductible for federal income tax purposes is limited to the $92 above that value.

  • Three numbers. What the guest paid, what they got and the difference, in that order.
  • IRS wording. The last sentence follows the IRS's disclosure wording.

Benefits you can leave out

Small tokens don't need disclosing. For 2026, a logo item such as a mug counts as one if it costs you $13.90 or less and the gift is at least $69.505. So do routine perks, like free admission, from a membership costing $75 a year or less.

Describe goods and services without valuing them

Describe property so someone could picture it two years from now: how many, what it is and its condition. The IRS's own sample letter thanks a donor for "a used oak baby crib and matching dresser"1, with no value. "Donated furniture" isn't a description; "40 folding tables and 160 stacking chairs, used" is.

Leave the dollar figure off, even if the donor asks. The value is theirs to claim, and your own estimate belongs in your books. A gift acceptance policy settles which goods you'll take before they arrive.

If a donor claims more than $5,000 for an item or a group of similar items, they'll ask you to sign Form 8283. The signer must be an official authorized to sign your tax returns, or someone specifically designated for that form6, so name that person now. Publicly traded stock needs no signature.

Signing confirms you received the property described, and the form says outright that it does not represent agreement with the claimed fair market value7. It also commits you to file Form 8282, copying the donor, if you sell or otherwise dispose of the property within three years.

Volunteers can't deduct the value of their time3, so no letter should price their hours. Unreimbursed costs of $250 or more are different. In an IRS example, a volunteer buys a $500 plane ticket to represent a charity at its convention1. They keep their own receipts, and your letter describes their services and whether they got anything back.

Send on time, then check the batch

A donor must have the letter by the day they file that year's return, or by its due date (including extensions) if that comes first. Charities typically send acknowledgments by the following January 311.

Date each gift by when the donor gave it. Publication 526 treats a mailed check as delivered on the day it was mailed3. A check postmarked December 31 counts for that year, even if you open it in January.

Before the batch goes out

  • Every gift was sorted by type before any letter was written
  • Cash letters for $250 or more say whether anything was given in return
  • Event letters show the payment, the value received and the difference
  • No letter for goods, stock or volunteer costs carries a dollar value
  • Every Form 8283 is with your authorized signer

When to bring in your accountant

This guide covers US federal rules and isn't tax advice. Ask your accountant or lawyer before you accept real estate, private company shares or a vehicle, which has its own IRS rules. Don't tell donors what they can deduct beyond the statements above.

For a personal note alongside the receipt, try the donor thank-you letter writer. For a whole batch, open this template with Edit with AI, and River sorts each gift to the letter it needs.

How to use this template

Use the files as they are, or open them in River. They come filled in with a made-up community health charity's quarter of 1,260 gifts, so you can see how a batch sorts before you add your own. Take each letter from Acknowledgment Letters and its exact sentences from Substantiation Language Note.

With Edit with AI, River asks for your gift export, details of any gala, auction or membership, and your current letter. It sorts every gift by the facts that change its wording and prices benefits only from an invoice, a quote or a comparable price. Then it tells you how much of the batch your standard letter fits. It won't value donated property or sign anything.

Exception Log

Illustrative, for a fictional community health nonprofit called Cedar Line Community Health. Fourth-quarter batch, 1,260 gift records, $493,582 recorded. 22 worked rows stand for the 448 gifts that routed away from the default letter. The last column is what makes this sheet persuasive to somebody who thinks the current process is fine.

Restricted grantReporting condition attached to the awardLetter 1Unrestricted gift of $25,000.00Record the restriction

Four of these are the shape of the whole problem. The physiotherapy lot sold below the value of what the winner received, so nothing is deductible and the letter has to say so; the sentence nobody wants to write is the one that makes the other 34 auction letters credible. The stock gift has three candidate dates and only the settlement date belongs on the letter. The 31 December check is in the donor's earlier year and the postmark is the evidence. And the recurring donor at $32 a month never has a single gift that reaches the threshold, so the annual summary everybody sends is a courtesy rather than the document the donor relies on.

Event total137$52,000$25,268$27,042

Two things fall out of pricing the benefit rather than asserting it. A letter set that states the amount paid tells 137 donors they may deduct $52,000, which overstates the deductible total by $24,958, and the disclosure that prevents it is worth $10 per contribution in penalty exposure, capped at $5,000 per event. The second is subtler: seven lots sold at or below the value of the item, and a negative deduction does not exist, so the deductible total across the auction is $18,210 rather than the $17,900 you get by subtracting one column total from the other. The per-lot floor is what makes those two figures differ, and the difference is exactly the lots somebody overbid on in the wrong direction.

Six letters cover 1,260 records, and the register is what makes the split visible: 812 records on the default letter, 276 on a template swap, and 172 the default letter states something untrue about. The three property gifts over $5,000 are the highest-value block in the batch at $41,800, and they are blocked on one signature from a named official rather than on any writing. The 137 gala letters that already went out are the reason the outstanding column reads 145 rather than 8: a letter that overstates a deductible amount is harder to withdraw than a letter that has not been sent, so re-issuing is slower than sending late would have been.

Common questions

What should a donation acknowledgment letter include?

Your organization's name, the amount of a cash gift or a description of donated property, and a statement that the donor received nothing in return. If they did receive something, describe it and give a good faith estimate of its value. Add the date of the gift. In the US, donors need this letter for any single gift of $250 or more.

Is a charity gala ticket tax-deductible?

Partly. Guests can deduct only what they paid above the value of what they received, so a $150 ticket to a dinner worth $58 leaves $92. When a ticket costs more than $75, the charity must say this in writing, with a good faith estimate of the dinner's value, on the invitation or acknowledgment.

Do monthly donors need an acknowledgment for each gift?

Not if each gift is under $250. Separate gifts aren't added together, so $50 a month never reaches the threshold. A dated year-end summary is still worth sending, because donors need a record of each cash gift they deduct. From 2026, people who don't itemize can deduct up to $1,000 of them, or $2,000 on a joint return.

When do acknowledgment letters have to be sent?

Early enough that the donor has it by the time they file that year's tax return, and no later than the return's due date, including extensions. Charities typically send them by January 31 of the following year. Sending each one within days of the gift spreads the work and doubles as a prompt thank-you.

Should an in-kind donation letter state the value?

No. Describe what you received, with quantities and condition, and leave the value to the donor, who claims it on their own return. If they claim more than $5,000, they'll ask you to sign Form 8283. That signature confirms you received the property, and the form says it isn't agreement with their value.

Is this donation acknowledgment letter template free?

Yes. Download the four Word documents and three CSV sheets with no signup. They come filled in with a made-up charity's quarter of 1,260 gifts, so you can see each letter and sheet at work before you clear them. Edit with AI opens the same template in River.

What does Edit with AI do?

It opens the template in a free River workspace. River asks for your gift export, any event details and your current letter, then sorts every gift by the facts that change its wording. It prices event benefits only from sources you give it and can draft the letters. It doesn't value donated property, sign forms or send anything for you.
