Donation Letter for Tax Purposes: Contents, Deadline, and Records

A donation letter for tax purposes is the written acknowledgment a charity gives you to substantiate a contribution, and the IRS requires one for every single gift of $250 or more before you can claim it as a charitable deduction. Without that letter in hand by the time you file, the deduction is disallowed, no matter how clearly the payment shows up on your bank statement.¹

When You Need a Written Acknowledgment

The formal letter requirement starts at $250 per contribution. The IRS looks at each payment on its own, so five separate $200 gifts to the same charity in the same year do not trigger the rule, even though they total $1,000. A single $300 check does.¹

For gifts under $250 you still need proof, just not the formal letter. A bank statement, canceled check, or credit card record showing the organization’s name, the date, and the amount will satisfy the IRS for smaller monetary contributions.² Many charities send acknowledgments for every gift as a courtesy, but below the $250 line it is a nicety rather than a legal requirement.

What the Letter Must Contain

Section 170(f)(8) of the Internal Revenue Code sets out what a valid acknowledgment has to say. The letter must include:¹

The amount of any cash contributed. For property, a description of what was donated, without stating a dollar value.
A statement of whether the charity provided any goods or services in return for the contribution.
If goods or services were provided, a good-faith estimate of their value. If the only benefit was an intangible religious benefit, such as admission to a religious ceremony, the letter must say so in place of a dollar estimate.

The IRS also expects the organization’s name to appear on the letter.³ Any useful acknowledgment will also carry the donor’s name and the date of the gift, though those details support your records rather than satisfy a specific statutory checkbox.

When you received something back, only the amount above the value of what you got is deductible. Pay $500 for a charity gala dinner valued at $150 and the deductible portion is $350.⁴ A well-drafted letter spells that math out so you are not left to work it out yourself.

Email is fine. The IRS lets charities deliver acknowledgments electronically, so a message sent to the donor’s email address meets the requirement without any paper or wet signature.²

The Deadline to Have the Letter in Hand

The statute uses the word “contemporaneous,” which has a hard meaning: you must have the acknowledgment by the earlier of the date you actually file your return for the year of the gift, or the due date of that return including extensions.¹ A December donor who files in February without the letter has already missed the window. Courts have enforced this strictly, disallowing deductions where the donor got the letter after filing.

The safer move is to ask for the letter soon after the gift rather than waiting until tax season. Established charities usually send acknowledgments automatically by late January, but smaller organizations sometimes need a reminder.⁵

Quid Pro Quo Contributions

When a payment is partly a gift and partly a purchase, tax law calls it a quid pro quo contribution. Charity auctions, benefit dinners, and memberships that include tickets or events all fall into this category. For any quid pro quo payment over $75, the charity has its own duty to send a written disclosure telling you how much of your payment is deductible and giving a good-faith estimate of the value of what you received.²

A charity that skips this disclosure faces a penalty of $10 per contribution, up to $5,000 per fundraising event or mailing. That penalty falls on the organization, but if the letter you receive from a gala or auction does not break out the value of what you got back, you are the one left guessing on your return. Ask the charity for a corrected version before you file.

A few benefits do not count against your deduction at all. Token items carrying the organization’s name or logo that cost the charity $14.10 or less, and annual membership benefits worth no more than $118 (such as free parking or a newsletter), sit inside safe-harbor exceptions the IRS updates periodically.

Extra Paperwork for Non-Cash Gifts

Donating clothing, furniture, art, or other property piles documentation on top of the standard acknowledgment. The rules step up with value:

Over $500: file Form 8283, Section A, with your return. Section A covers items or groups of similar items valued between $500 and $5,000.⁶
Over $5,000: complete Section B of Form 8283 and obtain a qualified appraisal from an independent appraiser. Both the appraiser and the charity must sign the form.⁷

Publicly traded securities are the main exception. Even if your stock gift is worth more than $5,000, you complete only Section A and no appraisal is needed, because the market sets the value.⁶

The charity’s signature on Section B does not mean the organization is agreeing with your appraised value. It only confirms the charity received the described property on the date shown, which surprises some donors during audits.⁸ Donated clothing and household items must also be in good used condition or better; if you claim more than $500 for a single item that does not meet that standard, you need the full Section B treatment with an appraisal.

Vehicles, Boats, and Airplanes

Donating a car, boat, or airplane worth more than $500 has its own paperwork. The charity must send you Form 1098-C, or an equivalent written acknowledgment, within 30 days, and the form itself controls your deduction amount.⁹ In most cases the deduction is limited to the gross proceeds the charity gets when it sells the vehicle, not the Kelley Blue Book value. Three exceptions let you claim full fair market value instead: the charity uses the vehicle significantly in its operations, makes material improvements to it, or gives or sells it at a steep discount to a person in need.¹⁰

Confirm the Charity Qualifies

A letter only produces a deduction if it comes from an organization the IRS recognizes for that purpose. The group must qualify under Section 501(c)(3), covering entities organized exclusively for charitable, religious, educational, scientific, or similar purposes.¹¹ Federal, state, and local government entities also qualify for gifts made for exclusively public purposes.

Churches, synagogues, mosques, and other houses of worship are automatically treated as tax-exempt under 501(c)(3) and do not need a formal IRS determination letter.¹² A donation to your local church is deductible even if the church does not appear in the IRS database.

For everything else, verify status through the IRS Tax Exempt Organization Search before relying on a letter.¹³ Organizations can lose exempt status by failing to file required returns, and a gift to a revoked organization does not produce a valid deduction no matter how polished the acknowledgment looks. Political groups, individuals, and most foreign organizations fall outside the deduction rules entirely, so a receipt from them is not a donation letter for tax purposes at all.

Recordkeeping After You File

Once the return is filed, keep the donation letters, bank records, appraisals, and any Forms 1098-C for at least three years from the filing date. That matches the general statute of limitations for IRS audits.¹⁴ If you carried excess contributions forward, hold the original documentation until three years after you file the return that uses up the last piece of the carryforward, which can stretch several years past the original gift.

Charitable deductions themselves go on Schedule A, with cash and non-cash gifts on separate lines and any Form 8283 attached where required.¹⁵ Losing a $250-or-greater acknowledgment after filing leaves no defense in an audit: the IRS will not accept a bank statement as a substitute for the formal letter, and the deduction goes away.
