Above $75 with anything given in return, a written disclosure is required of your organization, not the donor. Most sample letters online mention neither. We read the two highest ranking collections of donor thank you letter samples. Between them they run to over nine thousand words. Neither mentions the IRS once. That is the gap. The letters are warm, the structure is fine, and they leave out the part that has legal consequences. This page covers both: what makes a thank you letter work, and what the IRS requires it to say. Everything below was read on the IRS website and in its own publications on 14 October 2026, and every source is listed at the end.

## What the IRS requires a thank you letter to say For a single contribution of $250 or more, the donor cannot claim a charitable deduction without a contemporaneous written acknowledgment from you. The IRS sets out exactly what it must contain:
What it has to include
1The name of your organization
2The amount of any cash contribution
3A description, but not the value, of any non cash contribution
4A statement that no goods or services were provided, if that is the case
5A description and good faith estimate of the value of any goods or services you did provide
6A statement if the only thing provided in return was intangible religious benefits
Three things worth knowing that often surprise people: You do not need the donor's Social Security or tax identification number. Do not ask for it. There is no IRS form for this. A letter or an email is fine. One annual summary can cover several gifts, or you can send one acknowledgment per gift. Both are acceptable. Author note. We build software that calculates donor numbers rather than estimating them, so a page about getting a letter legally right is squarely our territory. It is also the reason the figures further down are dated and sourced rather than repeated from another blog. ## The $250 rule The threshold applies to a single contribution, not to the total a donor gives you in a year. Twelve monthly gifts of $30 never trigger it. One gift of $250 does. Below $250 the full acknowledgment is not required, but you still matter. The donor needs either a bank record or a timely written communication from the organization, and the IRS says a receipt, a letter or an email all count. So the thank you letter for a $40 gift is not only good manners. It is the document that lets the donor claim it. "Contemporaneous" has a specific meaning: the donor must have it by the earlier of the date they file their return, or the due date including extensions. In practice the IRS notes that charities typically send written acknowledgments no later than 31 January of the year following the donation. ## The $75 rule almost nobody mentions This is the one missing from every sample letter collection we read, and it is the only part of this that is an obligation on your organization rather than on the donor. If a donor pays more than $75 and receives goods or services in return, you are required to provide a written disclosure statement. A gala ticket. A dinner. A round of golf. An auction item. The statement has to tell the donor that only the amount above the value of what they received is deductible, and it has to give a good faith estimate of that value. Two practical points the IRS makes that are worth repeating: It can go on the ticket page. The disclosure must be furnished in connection with either the solicitation or the receipt, so you can handle it at the point of sale rather than waiting for a letter. Small print may not be enough. The IRS says the statement must be made in a manner likely to come to the donor's attention, and that a disclosure in small print within a larger document might not meet the requirement. And there is a penalty. It is $10 per contribution, capped at $5,000 per fundraising event or mailing. An organization can avoid it by showing the failure was due to reasonable cause. For a gala with three hundred guests where nobody wrote the disclosure, that is the cap, reached easily. No disclosure is required where what the donor got meets the token exception, the membership exception or the intangible religious benefits exception, or where there was no donative element at all, such as an ordinary purchase in a museum gift shop. ## The token exception, and the figures most articles get wrong Small items given in return do not have to be described at all. A mug with your logo does not turn a gift into a quid pro quo contribution. Here is where almost every article on this subject goes wrong. IRS Publication 1771 gives the limits as $125, $62.50 and $12.50. It is the document everybody cites. Its own footnote says: "The dollar amounts are for 2023. Guideline amounts are adjusted for inflation." Publication 1771 has not been revised since November 2023. So an article quoting those figures today is quoting numbers that are three years old. The current figures, from Revenue Procedure 2025-32, for tax years beginning in 2026:
GuidelinePublication 1771 still printsCurrent for 2026
Low cost article$12.50$13.90
Insubstantial benefit, lower$12.50$13.90
Insubstantial benefit, middle$62.50$69.50
Insubstantial benefit, upper$125$139
So in 2026, a logo mug costing you $13.90 or less, given to somebody who gives $69.50 or more, can be treated as though nothing was provided. The $250 and $75 thresholds are statutory and do not move. Only these guideline amounts adjust each year, which means they need checking against the current Revenue Procedure annually. Including ours. And there is an intangible religious benefits exception. If a religious organization provides only intangible religious benefits, the acknowledgment does not have to describe or value them. The IRS gives admission to a religious ceremony as an example, along with a de minimis item such as wine used in a ceremony. It does not cover education leading to a recognized degree, so a faith school cannot use that wording for tuition. There is also a membership exception. An annual membership benefit counts as insubstantial if it is given for an annual payment of $75 or less and consists of recurring rights such as free or discounted admission, gift shop discounts, free parking, or member only events. For a museum, a zoo or an arts organization this is the rule that matters most, and we have never seen it in a thank you letter guide. ## The fourteen situations, and which letter each one needs Thank you letters fail when one template gets used for everything. These are the situations that genuinely need different wording, and what changes in each.
SituationWhat changes
First gift, under $250No full acknowledgment required, but the letter is the donor's written communication. Focus on the second gift
First gift, $250 or moreThe compliance line becomes mandatory
Repeat donorName the giving history. It is what makes the letter different from the first one
Major giftSpecific to the conversation you had. Call before you write
Monthly donorAn annual summary in January, listing each gift
In memory or in honourNotify the family separately and never disclose the amount
Event ticket or dinnerThe $75 disclosure, with a good faith estimate
Year end summaryOne acknowledgment substantiating several gifts
In kind or non cashDescribe what you received. Never state a value
MembershipDepends entirely on whether the annual payment is above or below $75
Volunteer expensesDescribe the services. Do not value their time, which is not deductible
Faith organizationThe intangible religious benefits wording, which does not cover tuition
School, college or alumniWatch for benefits attached to giving levels, which can make it quid pro quo
Corporate sponsorshipValue every benefit, including advertising and hospitality, not just the tickets
Two of these catch people out regularly. Non cash gifts. Describe the item, never put a number on it. Valuing a donated item is the donor's responsibility, and writing "valued at $4,000" into your letter can cause them a problem you did not intend. Vehicles, boats and aircraft claimed above $500 have separate rules in IRS Publication 4302. Volunteer time. Donors cannot deduct the value of their time, however much it is worth. They may be able to deduct unreimbursed expenses, and at $250 or more that needs an acknowledgment describing the services they provided. Publication 526 sets out when those expenses qualify. ## What makes a thank you letter work, beyond compliance Compliance keeps you out of trouble. It does not make anybody give again. These are the things that do, and none of them take longer. Be specific about one thing. Not the mission. One concrete sentence about what this size of gift actually pays for. A person can picture a number of meals or an hour of somebody's time. Nobody can picture "advancing our mission". Promise to report back, then do it. The promise costs nothing and the follow up is what separates organizations donors stay with from organizations they drift away from. Name the history. "This is your fourth gift" is a different letter from "thank you for your gift", and it requires nothing but a system that can tell you. That is the job our [donor thanking page](/thank-your-donors) describes. Do not ask for money in the thank you. It is the one piece of advice everybody agrees on and the one most often ignored. Why any of this matters more than it sounds. A donor who gave once renews at around 7 percent. A donor who gave twice renews at around 19 percent. Getting a second gift out of a first time donor is the single highest leverage thing in fundraising, and the acknowledgment is the first move in it. Our [guide to fundraising metrics and benchmarks](/blog/fundraising-metrics-benchmarks) shows the full retention picture, and the [fundraising plan guide](/blog/fundraising-plan-template) shows what it does to next year's goal. ## When to send
Gift typeSend by
Any giftWithin 48 hours if you can. The speed is noticed
Any gift of $250 or moreBefore the donor files their return, at the latest
Annual or year end summaries31 January of the following year, which is the convention the IRS itself names
Quid pro quo disclosureAt solicitation or at receipt. Earlier is better
## The mistakes that cost you Putting a value on a non cash gift. You describe, the donor values. Every time. Using the no goods or services line when goods or services were provided. The sentence is doing legal work. It has to be true. Disclosing the amount of a memorial gift to the family. Tell them a gift was made. Never tell them what it was. Forgetting the event disclosure. It is a requirement with a penalty attached, and it is the most commonly missed item on this page. Quoting the 2023 token figures. Including, until today, almost everybody writing about this. Sending the same letter to a first time donor and a fifteen year donor. Legal, and a waste of the only moment in the year when they are definitely paying attention. ## Where Gratefully fits Disclosure. Gratefully makes donor intelligence software, so read this with that in mind. We are also not a law firm, and nothing here is tax or legal advice. Every claim links to the IRS page or publication it came from, the rules change, and anything that matters should go past your own adviser. Everything on this page works with a word processor and an hour. If that is all you needed, take it. What the letters above ask you to do by hand is the part our product does automatically: knowing that this is somebody's fourth gift, that the last one was in memory of their mother, that they have given every March for six years, and drafting the letter with those facts already in it. Gratefully reads the CRM you already use, including Salesforce Nonprofit Cloud and NPSP, Bloomerang, Little Green Light, HubSpot and Blackbaud Raiser's Edge NXT, and every number it puts in front of you is calculated from your own records and cited back to them. Nothing reaches a donor without a person approving it. What it does not do. It is not a CRM and does not replace one. It does not do wealth screening or assign capacity ratings. It does not research individual donors. And it does not give tax advice, which is why this page sends you to the IRS rather than to us. If writing these by hand is the problem rather than the letters themselves, our [pricing is published](/pricing) and the free plan takes your whole donor file. ## Sources - [IRS, Charitable contributions: Written acknowledgments](https://www.irs.gov/charities-non-profits/charitable-organizations/charitable-contributions-written-acknowledgments).

The donor cannot claim a charitable deduction without a contemporaneous written acknowledgment from the organization. Below $250 the donor needs either a bank record or a written communication from the charity, and a letter or an email satisfies that. ### What are the IRS requirements for a donation receipt? The acknowledgment must contain the organization's name, the amount of any cash contribution, a description but not the value of any non cash contribution, a statement that no goods or services were provided if that is the case, a description and good faith estimate of any goods or services that were provided, and a statement if the only benefit was intangible religious benefits. ### Do you need a donor's Social Security number on a donation receipt? No, and you should not ask for it. The IRS does not require the donor's Social Security or tax identification number on a written acknowledgment. There is also no IRS form to use: a letter or an email is acceptable. One annual summary may substantiate several gifts, so you can choose between a statement per gift and a single year end letter. ### How much can someone donate before a receipt is required? There is no floor on keeping a record. What changes at $250 is who carries the burden: at or above that figure, for a single contribution, the organization has to issue a contemporaneous written acknowledgment containing six specific elements. Below it the donor may rely on a bank record instead, so a missing letter is recoverable. Above it, it is not. ### What is a quid pro quo contribution? A payment where the donor receives goods or services in return, such as a gala ticket or a dinner. Where the payment is more than $75, the charity is required to give the donor a written statement with a good faith estimate of what they received, making clear that only the amount above that value is deductible. ### Is there a penalty for not sending a donation disclosure? Yes. The penalty for failing the written disclosure requirement on quid pro quo contributions is $10 per contribution, capped at $5,000 per fundraising event or mailing. It can be avoided by showing the failure was due to reasonable cause. ### When should a nonprofit send donor thank you letters? As quickly as possible, and within 48 hours where you can manage it. For tax purposes the donor needs the acknowledgment before they file their return. The IRS notes that charities typically send written acknowledgments no later than 31 January of the year following the donation. --- Canonical HTML version: https://gratefully.io/blog/donor-thank-you-letter-templates More about Gratefully: https://gratefully.io/ai-instructions
