Pledge letters for nonprofits: the confirmation, the payment acknowledgment and the reminder — and why only the payment is a tax document
A pledge is a promise to give, and the IRS lets a donor deduct it only in the year each installment is actually paid. That splits the paperwork in two: ordinary letters that confirm the pledge and remind the donor (never dressed up as receipts), and a proper acknowledgment, with the amount, the date and the no-goods-or-services statement, for every payment that arrives. All four templates are below, with the year-end timing rules for December checks, the donor-advised fund trap and what to do about fun-run pledges.

Which letter, when
| Moment | Letter | Tax document? | Must say | Must not say |
|---|---|---|---|---|
| Donor signs the pledge card | Pledge confirmation | No | Total, schedule, thanks, "this is not a tax receipt", acknowledgments will follow each payment | "Your contribution of $[total]"; the no-goods-or-services sentence |
| An installment arrives | Payment acknowledgment | Yes (required at $250+) | Amount received, date, no goods or services were provided (or the quid pro quo disclosure) | Unpaid balance folded into the "contribution" amount |
| An installment is late or due | Pledge reminder | No | Paid to date, amount due, how to pay, the December 31 mail rule | Anything that reads as a receipt |
| January | Year-end statement | Yes | Every payment received in the year, dates, amounts, goods-or-services statement | Pledged-but-unpaid amounts |
Four mistakes small nonprofits make with pledges
- Receipting the promise. A confirmation that says "thank you for your contribution of $25,000" with the IRS sentence under it is a $25,000 receipt in the donor's file, five years early. Confirm the pledge in plain words and leave the compliance language for the payments.
- Totalling paid and unpaid on the year-end statement. The statement is a list of what was received. Put the balance in a separate reminder.
- Letting a DAF pay a binding pledge. The donor's sponsor may refuse the grant, or the donor may face the §4967 excise tax. Word pledge forms for DAF donors as non-binding intentions and never describe a sponsor's grant as a pledge payment (see the DAF page).
- Losing the December postmark. A check mailed December 30 and deposited January 5 is a prior-year gift for the donor (Treas. Reg. §1.170A-1(b)). Keep late-December envelopes, or note postmarks in the Notes column, so the acknowledgment and the donor's return agree.
Pledge confirmation letter (not a tax receipt)
Send when the pledge card comes in. Warm, specific about the schedule, and explicit that acknowledgments follow each payment.
[Organization legal name] [Mailing address] EIN [00-0000000] [Date] [Donor name] [Donor address] Dear [Donor first name], Thank you for your pledge of $[total pledge] to [campaign or fund], payable [in [n] installments of $[amount] by [schedule], e.g. "in four annual installments of $2,500 each December" / "by December 31, 2027"]. Your commitment lets us plan [what the pledge makes possible] with confidence. This letter confirms your pledge; it is not a tax receipt. Pledges are deductible only when paid, so we will send you a written acknowledgment for each payment as we receive it, and your year-end statement will list the payments made during the year. You can pay by check payable to [Organization legal name], online at [URL], or by stock or IRA transfer — just let us know so we can match the payment to your pledge. [If you wish to recommend grants from a donor-advised fund toward this commitment, please contact us first; DAF grants cannot be used to pay a binding pledge.] With gratitude, [Signer name] [Title]
Pledge payment acknowledgment (IRS-compliant)
Every element of Publication 1771 for the payment, then the running balance in its own paragraph.
[Organization legal name] [Mailing address] EIN [00-0000000] [Date] [Donor name] [Donor address] Dear [Donor first name], Thank you for your contribution of $[payment amount], received on [date received], as a payment toward your pledge to [campaign or fund]. No goods or services were provided in exchange for this contribution. For your records: this payment brings the total paid toward your $[total pledge] pledge to $[paid to date]; $[balance] remains, with your next installment scheduled for [date]. Only the amounts you have actually paid are deductible, so please keep this letter with your tax records. [One or two sentences about what the gift makes possible.] With gratitude, [Signer name] [Title] [Organization legal name] is a tax-exempt public charity under Section 501(c)(3) of the Internal Revenue Code.
Pledge reminder letter
For a due or overdue installment. Includes the year-end mail rule and an easy way to adjust the schedule, so a reminder never reads as a dunning notice.
[Organization legal name] [Mailing address] [Date] [Donor name] [Donor address] Dear [Donor first name], A friendly reminder about your pledge of $[total pledge] to [campaign or fund]. According to our records you have paid $[paid to date], and an installment of $[amount] is due on [date]. If you have already sent it, thank you — and please disregard this note. To pay, send a check payable to [Organization legal name] to the address above, give online at [URL], or transfer stock or make an IRA qualified charitable distribution (ask us for instructions). A check mailed by December 31 counts as a [year] gift even if we deposit it in January; online gifts count on the date charged. If your circumstances have changed and you would like to adjust the schedule, just reply to this letter or call [phone]. We are grateful for your partnership and happy to work with you. Warm regards, [Signer name] [Title] This reminder is not a tax receipt. You receive a written acknowledgment for each payment when it arrives.
Pledge card
A one-page card for appeals and campaign events: total, schedule, how the name should appear, matching gifts, stock and IRA options, and the DAF caution.
[Organization name] — [Campaign] pledge card Yes, I/we pledge a total of $________ to [campaign or fund], to be paid: [ ] in full by ____/____/______ [ ] in ____ installments of $________ each, [ ] monthly [ ] quarterly [ ] annually, beginning ____/____/______ Name(s) exactly as they should appear: ______________________________ Address: ______________________________ Email / phone: ______________________________ [ ] Please list my/our gift as Anonymous. [ ] My employer ______________________ matches gifts; I will submit the match request after each payment. [ ] I may pay part of this pledge by stock or IRA distribution — please send transfer instructions. Signature: ______________________________ Date: ____/____/______ Pledges are deductible only when paid. [Organization name] will send a written acknowledgment for each payment. Please do not use a donor-advised fund to pay this pledge without speaking with us first.
Installment letters and year-end statements from the payments spreadsheet
One row per payment (date paid, amount paid) with the campaign or Pledge payment 2 of 4in a Notes or Fund column. Per-gift mode writes an acknowledgment for each installment; year-end mode combines a donor's payments into one statement with every date and amount. Unpaid pledges have no row, so they never leak into a receipt — and in free-text mode a line that says someone pledged an amount is skipped with a warning until it says they paid it.
Pledge questions
Is a pledge tax-deductible when the donor makes it?
No. A pledge is a promise, and the deduction belongs to the year each payment is actually delivered (IRS Publication 526, "Time of making contribution"; Treas. Reg. §1.170A-1(b)). A donor who pledges $5,000 in November and pays $1,000 in December deducts $1,000 that year. The same is true of a promissory note given to a charity: it becomes a contribution only as the payments are made. So the charity acknowledges payments, never the pledge itself.
Does a pledge confirmation letter have to follow the IRS wording?
It must not look like a receipt. A confirmation can repeat the total, the schedule and your thanks, but should say plainly that it is not a tax receipt and that acknowledgments will follow each payment. Reserve the §170(f)(8) elements (amount received, date, no-goods-or-services statement) for the payment letters, so a donor's preparer never mistakes a $25,000 pledge confirmation for a $25,000 gift.
Does every pledge payment need its own letter?
Only payments of $250 or more need a contemporaneous written acknowledgment, and one year-end statement listing every payment with its date and the goods-or-services statement satisfies that for all of them. Most small organizations send a short acknowledgment after each installment anyway, because it doubles as a receipt and a thank-you and keeps the pledge visible to the donor. The year-end mode of the generator produces the statement; per-gift mode produces the installment letters.
Can the payment acknowledgment mention the remaining balance?
Yes, and donors appreciate it. Keep the two ideas in separate sentences: first the acknowledgment ("your contribution of $1,000 received on March 1; no goods or services were provided"), then the bookkeeping ("this brings the total paid toward your $5,000 pledge to $3,000; $2,000 remains"). Never phrase the pledge total as the contribution, and do not add unpaid installments to a year-end giving total.
A donor mailed the December installment on December 31 and it arrived January 4. Which year?
The year it was mailed. Under Treas. Reg. §1.170A-1(b) a check that is unconditionally delivered or mailed, and clears in due course, is a contribution on the date of delivery or mailing, so a December 31 postmark is a gift in that year. Credit-card payments count on the date charged (Rev. Rul. 78-38), pay-by-phone bank payments on the date the bank pays (Rev. Rul. 80-335), text-to-give gifts on the date the text is sent, and electronic stock transfers when the shares reach your account. Your acknowledgment states the date you received the payment; the donor's return reflects the delivery date, so it helps to keep the envelope or note the postmark for late-December mail.
Can a donor pay a pledge from a donor-advised fund?
Not safely if the pledge is legally binding. A DAF grant that satisfies the advisor's personal obligation is a more-than-incidental benefit taxed under IRC §4967. IRS Notice 2017-73 proposed relief where the sponsor makes no reference to a pledge, the advisor receives no other benefit and claims no deduction, and many sponsors now follow it, but the safest practice is to word pledge forms as non-binding statements of intent for donors who plan to give through a DAF, and never to send a DAF sponsor a letter describing the grant as a pledge payment. See the donor-advised fund page for the grant letters.
Can a private foundation or a company pay a board member's personal pledge?
A private foundation cannot: paying a disqualified person's legally binding pledge is self-dealing under Treas. Reg. §53.4941(d)-2(f)(1), even though the charity benefits. A company may pay, but then the company is the donor and gets the acknowledgment; the individual whose name was on the pledge card has not made a gift. In both cases acknowledge the entity whose money arrived, and note the pledge relationship separately in your records.
Is a pledge legally enforceable, and do we have to record it as revenue?
Whether a signed pledge is a binding contract is a question of state law; courts in many states enforce written pledges the charity relied on, though almost no small nonprofit sues a donor. Accounting is a separate question: organizations keeping accrual (GAAP) books record an unconditional promise to give as revenue and a pledge receivable when the promise is made (ASC 958-605), and report the receivable on Form 990 Part X. Cash-basis organizations record pledges only when paid. None of this changes the donor's tax year or your acknowledgment letters.
What about fun-run, walk-a-thon and read-a-thon pledges?
The people who pay are the donors. A grandparent who pledged $1 per lap and pays $26 has made a $26 gift and gets an acknowledgment if they want one (required only at $250 or more); the child who ran is not a donor. Keep the pledge sheet so each sponsor's name, amount and payment date are recorded; if a participant hands in a lump of cash with no names, you can only acknowledge the person who handed it in for what they personally gave. The PTA page covers the rest of school fundraising.
Should unpaid pledges appear on the year-end giving statement?
No. The statement lists contributions received during the year, with dates and amounts and the goods-or-services statement. An unpaid balance belongs in a separate reminder letter, which can go in the same envelope as long as it is a different document and clearly labelled as not a tax receipt. A statement that totals paid and unpaid amounts together invites an over-claimed deduction.
How do employer matching gifts work with pledges?
Employers match payments, not promises, and most require the employee to submit the match request after each installment with proof of payment, which is your acknowledgment letter. The match, when it arrives, is the company's own contribution: acknowledge it to the company and soft-credit the employee. Do not count a pending match toward the donor's pledge balance until the funds arrive.
How does the generator handle pledges and pledge payments?
Pledge payments are ordinary gifts: one row per payment with the date paid and the amount paid, and the campaign or "Pledge payment 2 of 4" in a Notes or Fund column. Unpaid pledges have no row. A pledge-tracking sheet can be pasted as it is: columns such as 'Pledge 2026' / 'Pledged' are read as the promise, 'Paid to Date' / 'Received YTD' / 'Amount Paid' as the money that actually arrived, and 'Balance' is ignored. Each letter acknowledges only the amount received, a notice shows how much of each pledge has been paid, and a household that has paid nothing yet gets no letter (with a plain-English reason instead). In free-text mode a line such as "Jane Doe pledged $500" is skipped with a warning, while "Jane Doe paid $500 toward her pledge on 3/1/2026" produces a letter.
