A contribution letter is a written acknowledgment that documents the transfer of money or property from one party to another. Most people encounter one in two situations: a charity issues it to a donor so the donor can claim a tax deduction, or a financial sponsor prepares one to prove they can support someone applying for a visa or admission to a U.S. school. The charitable version is governed by federal tax law, and if you gave $250 or more to a qualified charity, you cannot deduct the gift without a letter that meets specific requirements.1Office of the Law Revision Counsel. 26 USC 170 – Charitable, Etc., Contributions and Gifts
What a Charitable Contribution Letter Must Contain
The letter has to come from the charity, not from you, and it has to be in writing. Under 26 U.S.C. ยง 170(f)(8), the acknowledgment must include:
- The full legal name of the charity that received the donation.
- The cash amount, or a description of donated property. For non-cash gifts, the charity describes what was given but does not have to assign a dollar value.
- A statement about whether the charity gave you anything in return. If it gave you nothing, the letter has to say so explicitly.
- If you did receive something back, a good-faith estimate of its fair market value.
The statute does not require your name, the exact date of the gift, or your Social Security number. Many charities include those anyway for their own recordkeeping, but the legal focus is the charity’s identity, the amount, and the quid pro quo disclosure.2Internal Revenue Service. Charitable Contributions – Written Acknowledgments
When you get the letter, read it the day it arrives. Confirm the charity’s name is correct, the amount matches your records, and the goods-or-services line is there. If anything is missing, ask for a corrected letter immediately. Fixing it before you file is easy. Fixing it after is not possible.
The Quid Pro Quo Rule Over $75
A separate rule applies when a charity receives more than $75 and provides you with something in return. The charity must give you a written statement telling you that your deductible amount is limited to what you paid minus the fair market value of what you got back, and it must include a good-faith estimate of that value.3Internal Revenue Service. Charitable Contributions – Quid Pro Quo Contributions
The classic example is a benefit dinner. Pay $500 for a ticket to a gala where the meal and entertainment are worth $150, and your deductible gift is $350. The charity is required to spell that out in writing. A charity that fails to make the disclosure faces a penalty of $10 per contribution, capped at $5,000 per fundraising event or mailing, unless it can show reasonable cause.4Office of the Law Revision Counsel. 26 USC 6714 – Failure to Meet Disclosure Requirements Applicable to Quid Pro Quo Contributions
When You Need the Letter By
Timing is where deductions quietly disappear. The acknowledgment must be “contemporaneous,” which the IRS defines as received on or before the earlier of two dates: the day you actually file your return for the donation year, or the due date of that return including extensions.1Office of the Law Revision Counsel. 26 USC 170 – Charitable, Etc., Contributions and Gifts
Most charities send letters by the end of January. If yours does not, and you file your return before the letter arrives, the deduction is gone. A supplemental letter fixing the omission after the fact does not rescue it. The IRS and the Tax Court have consistently held that a late letter is a worthless letter, even when nobody disputes the donation happened.5Internal Revenue Service. Publication 526 – Charitable Contributions If you made a large year-end gift, confirm the letter is in hand before filing.
Extra Paperwork for Property Donations
Donating property instead of cash triggers requirements beyond the acknowledgment letter, and they scale with the claimed value.
- Over $500: You file Form 8283 with your return, describing the property, how you acquired it, and its fair market value.6Internal Revenue Service. Instructions for Form 8283
- Over $5,000: You generally need a qualified appraisal by an appraiser who holds a recognized designation or has at least two years of relevant experience. The appraisal must be signed and dated no earlier than 60 days before the donation, and the appraiser’s fee cannot be a percentage of the appraised value.7Internal Revenue Service. Instructions for Form 8283
- Over $500,000, or over $20,000 for art: You attach the full qualified appraisal to your return.7Internal Revenue Service. Instructions for Form 8283
Clothing and household items have their own condition rule: each item has to be in good used condition or better to be deductible at all. To claim more than $500 for a single item that does not meet that standard, you need a qualified appraisal attached to your return. The charity’s acknowledgment alone will not carry a high-value non-cash gift.
What Happens If the Letter Is Missing or Wrong
The penalty is blunt. You lose the entire deduction. The IRS does not prorate it, reduce it, or open a window for correction after the filing deadline. This is one of the stricter rules in the code, and courts have enforced it even where the donation itself was not in dispute. A letter that lists the amount but omits the goods-or-services statement is defective, and a corrected letter that arrives after you file cannot cure the defect.1Office of the Law Revision Counsel. 26 USC 170 – Charitable, Etc., Contributions and Gifts
Contribution Letters Used for Immigration and School Sponsorship
A separate kind of contribution letter appears when someone sponsors a family member for a visa or a student for admission. The formal document in the family immigration context is the Affidavit of Support (Form I-864), a legally binding contract with the federal government. Sponsors often submit a financial contribution letter alongside it.
The sponsor has to show income at or above 125% of the federal poverty guidelines for the household size, and the commitment is not casual. If the sponsored immigrant later receives means-tested public benefits, the agency that paid those benefits can sue the sponsor to recover the cost plus legal fees.8U.S. Citizenship and Immigration Services. Affidavit of Support Under Section 213A of the INA
A sponsorship contribution letter typically includes the sponsor’s full legal name, address, phone number, and relationship to the person being sponsored; the specific dollar amount pledged annually or the total balance being made available; and supporting evidence such as recent bank statements, tax returns with W-2s or 1099s, and employment verification. For F-1 international students, the school’s international office generally wants the sponsor’s name, relationship to the student, total support in U.S. dollars, and duration of the commitment, with the letter issued within the past six months and in English or accompanied by a certified translation.
These letters do not substitute for the charitable acknowledgment rules, and a charity’s letter does not satisfy USCIS. The two use the same name and nothing else.
How Long to Keep the Letter
The general IRS rule is to keep records supporting a return for three years after filing. That extends to six years if you underreport income by more than 25%, and seven years for a deduction tied to worthless securities or bad debt.9Internal Revenue Service. How Long Should I Keep Records
Three years covers most donors, but because the cost of losing a single letter is the entire deduction, six years is a safer floor. Keep the original and a digital scan; the IRS accepts electronic records as long as they are legible and accessible.
Sponsorship letters are different. The financial commitment under an I-864 lasts until the sponsored immigrant becomes a U.S. citizen, can be credited with 40 qualifying quarters of work, dies, or permanently leaves the country. Keep those records for as long as the obligation runs, which can be well over a decade.
