501(c)(3) booster club donation letter: what to include

Last updated 2026-08-14

What does a 501(c)(3) donation letter need to say?

A donation acknowledgment letter needs four things to hold up for a donor's tax return: the booster club's legal name, the date of the contribution, the amount (for cash gifts) or a description (for non-cash gifts), and a statement about whether the donor got anything back for it. That last part matters more than people think. The IRS puts it plainly in Publication 1771: a donor can't claim a deduction of $250 or more "unless the donor obtains a written acknowledgment from the charitable organization." ^[1] The acknowledgment has to include "a statement that no goods or services were provided by the organization in return for the contribution, if that is the case." ^[1] If the donor did get something, a banquet ticket, a spirit-wear item, a round of golf, the letter has to say what it was and give a good-faith estimate of its value. Here's the plain-English version: if a booster parent writes a check for $500 and gets nothing back, your letter says so. If they pay $500 for a golf tournament that includes a $60 dinner, your letter says the payment was $500 and the deductible portion is $440, because $60 of fair market value came back to them. You don't need special software or a fancy template. A one-page letter on club letterhead, signed by the treasurer or president, does the job. What you can't skip is the EIN. Donors and their accountants use it to verify your exempt status against the IRS Tax Exempt Organization Search, and without it the letter looks homemade even when it's accurate.

When is a booster club legally required to send one?

The $250 threshold is the trigger, and it applies per contribution, not per donor per year. IRS guidance says organizations "must provide a written disclosure statement to donors" for quid pro quo contributions over $75, and a separate written acknowledgment is needed for any single donation of $250 or more to be deductible. ^[1][2] A few practical notes booster treasurers get wrong constantly: First, it's the donor's responsibility to get the acknowledgment before filing their return, but it's your club's responsibility to provide one on request, and providing it proactively (right after the gift, or in a year-end batch) saves you a hundred follow-up emails in March. Most well-run booster clubs send letters within a few weeks of the gift and again as a summary at year-end for recurring donors. Second, the $250 rule is about individual gifts, so if a parent gives $100 four separate times, none of those single gifts trigger the requirement, even though the annual total is $400. Some clubs send letters for every gift regardless of amount anyway, just for goodwill and recordkeeping. That's a fine practice, not a legal requirement. Third, membership dues, raffle ticket purchases, and auction item purchases are usually NOT fully deductible gifts, because the donor received something (raffle chance, dinner, merchandise) in return. Treat these differently from a straight cash donation. If you're not sure how to split a hybrid payment, that's exactly the kind of question to ask your tax advisor, not guess at.

What if the donor gets something back (quid pro quo gifts)?

Quid pro quo means the donor paid you and received something of value in return, even partially. The IRS defines a quid pro quo contribution as "a payment a donor makes to a charity partly as a contribution and partly for goods or services." ^[2] Booster clubs run into this constantly: golf tournaments, gala dinners, raffle tickets, car magnets given for a minimum donation. The rule from IRS Publication 1771: for any quid pro quo contribution over $75, the organization must give the donor a written statement that (1) informs them only the amount exceeding the fair market value of the goods or services is deductible, and (2) provides a good-faith estimate of that fair market value. ^[1] A simple example: a booster club sells $100 tickets to a dinner dance where the meal and entertainment are worth $35 per person. The acknowledgment letter should state the payment was $100, the fair market value received was $35, and $65 is the deductible portion. Get the valuation wrong (too low or unstated) and you've put the donor at risk in an audit, not yourself directly, but it damages trust and could bring complaints back to your board. Small token exceptions exist. Insubstantial items like a mug or pin under a certain low-cost threshold don't have to be subtracted out, but the thresholds are IRS-published dollar figures that change periodically. Confirm the current insubstantial-value threshold with the IRS before treating any "free gift" as exempt from this calculation.

Does the letter need our EIN, and where do we get one?

Yes. Include your EIN on every donation letter. It's the single fact a donor's accountant checks first, and it's also what lets anyone verify your organization on the IRS's public exempt organization database. If your booster club doesn't have an EIN yet, you apply for free directly through the IRS, using Form SS-4 or the online EIN assistant. There is no legitimate paid "EIN service" you need; the IRS issues EINs at no cost. ^[3] If your club has an EIN but isn't sure it's still recognized as tax-exempt (a common problem after officer turnover), search the organization by name or EIN in the IRS Tax Exempt Organization Search tool before you promise donors a deduction in writing. Auto-revoked organizations show up there too, and that status affects whether your donation letters carry any tax weight at all. For background on what auto-revocation means and how to recover from it, see our form 990 explainer.

What is Form 990, and how does it connect to donation letters?

Form 990 is the annual information return that most tax-exempt organizations, including many booster clubs, file with the IRS to report income, expenses, and activities. It's a separate document from a donor acknowledgment letter, but the two are connected: your 990 (or 990-N) filing history is part of what keeps your exempt status active, and an active exempt status is what makes your donation letters meaningful to donors. Small organizations with gross receipts normally $50,000 or less can file the e-Postcard version, Form 990-N, instead of the full form. ^[4] Organizations above that threshold file Form 990-EZ or the full Form 990 depending on revenue and assets. Confirm your club's current filing tier with the IRS, since thresholds and forms have shifted over the years. Here's the failure mode booster treasurers run into: a club skips its 990/990-N filing for three consecutive years, then the IRS automatically revokes its tax-exempt status. ^[5] Once revoked, any donation letter you send claiming deductibility is, strictly speaking, inaccurate, because the organization is no longer a recognized 501(c)(3) until it's reinstated. If your club has missed filings, read our guides on ^[990](/articles/treasurer-basics/990), 990-N, and Form 990-N before you send another acknowledgment letter promising a deduction.

What is the 990 tax form, exactly, and who has to file it?

The 990 tax form is the IRS's annual reporting form for tax-exempt organizations, used to disclose revenue, expenses, program activities, and, for larger organizations, officer compensation and governance policies. It exists so the IRS and the public (990s are public record) can see how a tax-exempt organization is spending its money. "Tax-exempt organizations, nonexempt charitable trusts, and section 527 political organizations file Form 990 to provide the IRS with the information required by section 6033," per the IRS instructions for the form. ^[6] Most small booster clubs with under $50,000 in gross receipts file the simplest version, Form 990-N (the e-Postcard), which just confirms basic identifying information online. ^[4] Clubs with more revenue file Form 990-EZ or the full Form 990, both of which ask for financial detail, more than a checkbox confirmation. See our irs form 990 and 990 tax form pages for a full breakdown of which version applies to your club's revenue tier and what happens if you file late.

What does a booster club treasurer actually do (and why does it connect to donation letters)?

A club treasurer keeps the books, tracks income and expenses, reconciles the bank account, and makes sure required IRS and state filings happen on time. That's the short answer to "what does a treasurer do": bookkeeping, filing compliance, and reporting to the board. Writing donor acknowledgment letters usually falls to the treasurer specifically, because it requires knowing exactly how much came in, whether anything was given in return, and what the club's current EIN and exempt status look like. A treasurer who doesn't track this accurately is the person who accidentally sends fifty letters overstating deductible amounts for a golf tournament. A useful mental model for what a club treasurer does: they are the one person who has to know, at any moment, (1) how much cash is in the account, (2) whether the 990/990-N was filed this year, (3) which donations crossed the $250 threshold and need letters, and (4) whether any fundraiser (raffle, auction, quid pro quo dinner) needs special disclosure language. Nobody else on a volunteer board typically tracks all four of those at once. If you're new to the role and inheriting someone else's mess of a spreadsheet, that's normal. Most volunteer treasurer handoffs happen with incomplete records. Start by pulling the last three years of 990/990-N confirmations and the last bank statement, then work forward from there.

Sample donation letter language (structure, not legal advice)

EIN and legal name	Required	Required
"No goods or services" statement	Required	Not used, replaced with value statement
Fair market value disclosure	Not needed	Required if payment exceeds fair market value received
Threshold that triggers requirement	$250 or more, per IRS Pub. 1771 [1]	Over $75, per IRS Pub. 1771 [1]
Common booster examples	Direct cash donation, matching gift check	Gala ticket, golf tournament entry, raffle ticket purchase	Don't laminate a single template and reuse it blindly for every fundraiser. A silent auction letter, a golf tournament letter, and a straight cash-gift letter all need slightly different language because the underlying transaction is different.

Below is a structural outline, not a template to copy verbatim without adapting it to your club's facts. Every bracketed section should reflect your actual situation, confirmed against current IRS guidance. A basic cash-gift letter (no goods or services given) should include: - Organization's legal name and EIN

• Statement: "[Organization Name] is a tax-exempt organization under Section 501(c)(3) of the Internal Revenue Code"
• Date of the contribution
• Amount of cash received
• The required statement: "No goods or services were provided in exchange for this contribution"
• Signature of an authorized officer (treasurer or president) A quid pro quo letter (something was given back) needs everything above, plus: - A description of what the donor received (dinner, golf round, merchandise)
• A good-faith estimate of the fair market value of that item
• The deductible amount (total payment minus fair market value) Here is a comparison of what changes between the two letter types: | Element | Straight cash gift | Quid pro quo gift |

What records should we keep alongside the letters?

Keep a donation log that lists donor name, date, amount, whether anything was given in return, the estimated fair market value of anything given, and the date the acknowledgment letter was sent. This is separate from your general ledger, though the totals should tie back to it. Why bother with a separate log? Because if the IRS or a donor's accountant ever asks for proof a letter was sent, "we think we emailed something in October" isn't good enough. A dated log entry is. Also keep a copy of every letter sent, ideally as a PDF, for at least as long as the IRS statute of limitations on the donor's return could reasonably reach back, generally three years from filing, longer in some fraud or substantial-understatement situations. This isn't a hard legal requirement for the charity itself, but it's the practical standard that keeps you covered if questions come up later. A related but separate issue: your club's own recordkeeping for the 990/990-N filing needs the same underlying donation data, just aggregated differently. If your log is clean, filing season goes from a nightmare to an afternoon.

What mistakes do new booster treasurers make with donation letters?

The most common mistake is sending a blanket "thank you for your tax-deductible donation" letter for a raffle ticket purchase or gala ticket, when in fact most or all of that payment isn't deductible because the donor received a chance to win or a meal in return. This creates real tax exposure for the donor, not you, but it's your name on the letter. The second most common mistake: letting the club's exempt status lapse (via 990/990-N non-filing for three straight years) and continuing to send letters claiming 501(c)(3) deductibility anyway. Once auto-revoked, the organization is off the deductible-donee list until reinstated, and letters sent during that gap are inaccurate on their face. Third: forgetting the EIN, or using an old EIN from a defunct predecessor organization. Booster clubs reorganize under new names surprisingly often (school district merges two programs, a club dissolves and reforms), and the new entity needs its own EIN and its own exemption determination, not a hand-me-down. Fourth: no fair market value estimate on quid pro quo letters, just a flat "thank you for your $150 donation" for a dinner that clearly included food and entertainment. That's the exact gap IRS Publication 1771 requires you to close. ^[1] If your club is untangling a messy handoff, a state-personalized Treasurer Kit can save real time by giving you letter templates and filing checklists built around your specific state's rules, for a one-time $99 rather than hourly accountant rates. It's not a substitute for professional advice on anything unusual, but for the routine 90% of booster club paperwork it covers the ground fast.

Do state charity registration rules affect our donation letters?

Yes, separately from the federal IRS rules above. Many states require charitable organizations, including booster clubs that solicit donations from the public, to register with a state charity official (often the Attorney General's office or Secretary of State) before soliciting, and some require specific disclosure language on solicitation materials. This is a state-by-state patchwork, and the requirements (registration thresholds, exemptions for small or volunteer-run groups, required disclosure text) genuinely differ. Confirm your specific state's charitable solicitation registration requirement and any required donor-disclosure language with your state's charity regulator or Attorney General's office before you finalize a donation letter template, especially if your club solicits donations online or across state lines. This is also the office to check before running a raffle, since raffle licensing and charitable solicitation registration frequently sit under the same state authority.

Frequently asked questions

What does a treasurer do in a booster club?

A booster club treasurer tracks all income and expenses, reconciles the bank account monthly, prepares financial reports for the board, and handles required IRS filings like Form 990-N or 990-EZ. They also typically write donor acknowledgment letters, since they're the one who knows exact amounts and whether anything was given in return for a gift.

What is Form 990?

Form 990 is the annual information return the IRS requires from most tax-exempt organizations, reporting revenue, expenses, and activities. Small organizations with gross receipts normally under $50,000 file the simplified Form 990-N e-Postcard instead. Filing keeps your organization's tax-exempt status active and its information available to the public.

What is the 990 tax form used for?

It's used by the IRS to verify that a tax-exempt organization is operating consistent with its exempt purpose, and it makes financial details public so donors and watchdogs can review them. Booster clubs, PTOs, and similar nonprofits file some version of it annually, based on their revenue tier.

Do we need a donation letter for every gift, no matter how small?

Legally, the IRS acknowledgment requirement only kicks in at $250 or more per single contribution, per IRS Publication 1771. Many clubs choose to send thank-you letters for smaller gifts too, for goodwill and recordkeeping, but it isn't a federal requirement below that threshold.

What must be in a 501(c)(3) donation acknowledgment letter?

It needs the organization's legal name and EIN, the date and amount of the gift, and a statement about whether goods or services were provided in return. If something was given, the letter must estimate its fair market value so the donor can calculate the deductible portion, per IRS guidance in Publication 1771.

What happens if our booster club lost its tax-exempt status?

If your club failed to file Form 990 or 990-N for three consecutive years, the IRS automatically revoked its exempt status. You can apply for reinstatement, but until that's approved, donations made during the gap generally aren't deductible, and your acknowledgment letters shouldn't claim 501(c)(3) status without confirming current standing with the IRS.

Can we deduct raffle ticket purchases the same way as cash donations?

No. A raffle ticket purchase is a quid pro quo transaction, since the buyer received a chance to win something. Generally none of the ticket price is deductible as a charitable gift, unlike a straight cash donation. Confirm treatment specifics with a tax advisor, since this trips up booster clubs constantly.

Where do we find our booster club's EIN if we've lost it?

Check old bank statements, past tax filings, or your original IRS determination letter. You can also call the IRS Business & Specialty Tax Line to request it, or search the organization by name in the IRS Tax Exempt Organization Search tool if you're registered as exempt.

Is a thank-you email enough, or does it need to be a formal letter?

The IRS doesn't require a specific format, a written acknowledgment can be a letter, email, or even a postcard, as long as it contains the required content: name, date, amount, and the goods-or-services statement. What matters is substance, not stationery.

What's the difference between a donation and a quid pro quo contribution?

A donation is a gift where the donor gets nothing tangible back. A quid pro quo contribution is partly a gift and partly a payment for something of value, like a gala dinner or golf round. Only the portion exceeding the fair market value received is deductible, per IRS Publication 1771.

Does our state require a separate charitable solicitation disclosure on donation letters?

Possibly. Many states require registration before soliciting donations and some mandate specific disclosure language on solicitation materials or receipts. This varies by state, so confirm current requirements with your state's Attorney General's office or charity regulator before finalizing your letter template.

Who should sign the donation acknowledgment letter?

Typically the treasurer or club president, as the authorized officer confirming the gift was received and describing the club's exempt status. There's no IRS requirement on title, just that someone authorized to speak for the organization signs it.
