TL;DR
A 501c3 booster club donation letter needs the organization's legal name, its tax-exempt status statement, the donation amount or item description, the date received, and a line confirming whether the donor got anything of value back. IRS guidance (Publication 1771) sets the substantiation rules donors need for gifts of $250 or more.
What does a 501c3 booster club donation letter need to say?
A donation acknowledgment letter from a booster club with 501(c)(3) status needs five things to actually be useful to the donor: your organization's legal name and address, a statement that you're recognized as tax-exempt under section 501(c)(3), the amount of cash received (or a description, not a value, of any donated property), the date of the contribution, and a statement about whether the donor received goods or services in exchange. That last part trips up more booster clubs than anything else. If a parent gives $500 and gets a team spirit pack worth $40, your letter has to say so and note the deductible amount is only $460. IRS Publication 1771 spells this out directly: "A donee organization must provide a written disclosure statement to donors" when a payment is more than $75 and is partly a contribution and partly for goods or services [1]. For gifts under $250, technically the IRS doesn't require the charity to send anything. The donor's own bank record or receipt is enough for their own tax filing. But smart booster clubs send a letter anyway, because it builds trust and because donors ask for one when tax season hits and they can't find their canceled check. Here's the one line that changes everything, straight from IRS guidance: for any single contribution of $250 or more, "the donor cannot claim a tax deduction... unless the donor obtains a written acknowledgment from the qualified organization" [1]. That's not the club's obligation to file anything with the IRS. It's the donor's obligation to have the letter in hand before they file their own return.
Example of a 501c3 booster club donation letter
Below is a working template you can adapt. Swap in your real club name, EIN, and board contact. Do not send this without confirming your own 501(c)(3) status is current, since a lapsed or auto-revoked exemption changes what you can honestly claim in writing. --- [Booster Club Legal Name] [Street Address, City, State, ZIP] [EIN: XX-XXXXXXX] [Date] Dear [Donor Name], Thank you for your generous contribution of $[amount] received on [date]. [Booster Club Name] is recognized by the IRS as a tax-exempt organization under Internal Revenue Code Section 501(c)(3). Our EIN is XX-XXXXXXX. No goods or services were provided in exchange for this contribution. [OR: In exchange for this contribution, you received [description of item/benefit], valued at approximately $[value]. The deductible portion of your gift is $[amount minus value].] Please retain this letter as your official record for tax purposes. Consult your tax advisor regarding the deductibility of this gift. Sincerely, [Name, Title] [Booster Club Name] --- That's the whole thing. It doesn't need to be long. It needs to be accurate and it needs the magic words 'no goods or services were provided' or an honest accounting of what was. One detail people skip: put your EIN on the letter. Donors' tax preparers ask for it, and it's a quiet signal that your organization actually exists as a registered entity, more than a parent group with a bank account.
Does a booster club need 501(c)(3) status to send donation letters?
Yes, in the sense that a letter claiming tax-deductibility only means something if the organization actually holds current 501(c)(3) status. A booster club that hasn't applied for exemption, or one that got auto-revoked for not filing Form 990 for three straight years, cannot honestly tell a donor their gift is tax-deductible. Auto-revocation is more common than people think. The IRS publishes an Auto-Revocation List, and thousands of small nonprofits land on it every year for missing three consecutive annual filings [2]. If your booster club hasn't filed anything since it was formed, or you're not sure the prior treasurer ever filed, check the IRS Tax Exempt Organization Search tool before you send another donation letter promising deductibility [3]. If your club is on that list, donations made during the revoked period are not automatically deductible to the donor, even if you send a letter saying so. You'd need to apply for reinstatement, sometimes retroactively, which involves refiling Form 1023 or 1023-EZ and, in many cases, back-filing the missed 990s. That process is worth reading up on separately; it's not something to guess your way through in a donor letter.
What is a treasurer, and what does a treasurer do in a booster club?
A treasurer is the club officer responsible for the money: tracking income and expenses, keeping bank accounts reconciled, filing the club's annual IRS return, and giving the board accurate financial reports. In a booster club or PTO, the treasurer is usually the only person who touches the actual books day to day, which makes the role higher-stakes than the title suggests. What does a treasurer do in practice? A typical month includes depositing concession stand cash, paying vendor invoices, updating a simple ledger or spreadsheet, and reconciling the bank statement against club records. At year-end, the treasurer (or whoever inherits the job) has to figure out which IRS form applies and file it on time. What does a club treasurer do differently from a corporate bookkeeper? Mostly, they do it with fewer resources and less oversight. Most booster club treasurers are volunteers, often serving one or two years before handing the job to the next parent. That turnover is exactly why documentation matters: donation letters, receipts, and the prior year's 990 filing need to be handed off cleanly, not reconstructed from memory.
What is Form 990, and does every booster club have to file it?
Form 990 is the annual information return the IRS requires most tax-exempt organizations to file, reporting revenue, expenses, and activities for the year. What is the 990 tax form used for? It's how the IRS (and the public) can see that a nonprofit is still operating and still eligible for its exempt status. Most small booster clubs don't file the full Form 990. If your gross receipts are normally $50,000 or less, you file Form 990-N (the e-Postcard) instead, which is a short online form, not a paper return [4]. Larger organizations file Form 990-EZ (gross receipts under $200,000 and total assets under $500,000) or the full Form 990 above those thresholds [5]. Here's the one number every booster treasurer should tattoo on their brain: miss three consecutive years of required 990 filings, and the IRS automatically revokes your tax-exempt status. No warning letter with teeth, no appeal before it happens. As the IRS puts it, organizations that don't file "for three consecutive years" have their exempt status "automatically revoked" [2]. That's the single most common way small booster clubs lose their exemption, not through any wrongdoing, just silence. For more on picking the right version and filing it correctly, see form 990 and 990-N.
What goods-or-services language actually belongs in the letter?
This is the part booster clubs get wrong most often, mostly because concessions, raffle tickets, spirit wear, and sponsorship banners all complicate a straightforward cash gift. If a donor gives money and gets literally nothing back (a straight check to the general fund, for example), the letter should say plainly: 'No goods or services were provided in exchange for this contribution.' That single sentence is what makes the full amount deductible. If the donor gets something, even something small, you have to value it and subtract it. Say a sponsor gives $1,000 and gets a banner at the football field valued at $150 (printing and installation cost, roughly). The deductible amount is $850, and your letter needs to spell out both numbers. IRS Publication 1771 requires this disclosure whenever a 'quid pro quo contribution' exceeds $75 [1]. There's a carve-out for token items. If the benefit is genuinely trivial (a bumper sticker, a pencil, low-cost items under IRS token exception thresholds), you generally don't have to net it out. IRS Publication 1771 describes this exception for items like "key chains, calendars, mugs, or posters" of low cost bearing the organization's name or logo, and for token benefits under a set low-dollar limit tied to the size of the gift [1]. But the dollar thresholds adjust for inflation most years, so don't guess; confirm the current figures in the latest Publication 1771 or with your own tax advisor before assuming an item qualifies.
When is the $250 threshold, and why does it matter for donation letters?
The $250 threshold is the line where a donor legally needs written acknowledgment from your organization before they can claim the deduction on their tax return. Below $250, a bank record technically suffices for the donor's own records; above it, no letter means no deduction, no matter how generous the gift. This is worth restating because parents ask about it constantly. IRS guidance is direct on this: for contributions of $250 or more, 'the donor cannot claim a tax deduction... unless the donor obtains a written acknowledgment from the qualified organization' [1]. It's the donor's responsibility to ask for the letter, but a well-run booster club sends one automatically for anything near or above that line, since waiting for a donor to ask in March creates a scramble nobody enjoys. Practical tip that isn't official IRS guidance but is just good practice: batch your acknowledgment letters. Send them within a few weeks of the gift, not at year-end in one exhausted push. Donors lose receipts; a prompt letter is often the only proof they'll ever have.
What records should the treasurer keep alongside the donation letters?
Every donation letter you send should have a matching internal record: the donor's name, amount, date, method of payment, and a copy of the letter itself, ideally in a shared drive the next treasurer can access without you. This matters for two reasons. First, if the IRS or a state charity regulator ever asks questions during an audit or a routine review, you want a clean paper trail, not a shoebox. Second, and more common in real booster club life, treasurers turn over every year or two. The single biggest failure point for small nonprofits isn't fraud, it's just lost institutional knowledge when one volunteer hands off to the next with a half-finished spreadsheet and no explanation. Keep a running donor log (spreadsheet is fine) noting every acknowledgment letter sent, and file copies by year. When your board treasurer changes, that log should transfer with the bank statements and the prior year's [990](/articles/treasurer-basics/990) or 990-N filing confirmation, not get left behind in someone's personal email.
What if the booster club isn't actually a registered 501(c)(3) yet?
If your booster club hasn't filed Form 1023 or 1023-EZ and received an IRS determination letter, you cannot legally tell donors their gifts are tax-deductible, even if you call yourselves a nonprofit or a 'booster club.' Being organized as a nonprofit under state law (incorporating as a nonprofit corporation) is a separate step from federal tax exemption, and donors need the federal piece for a deduction. Check your status using the IRS Tax Exempt Organization Search, which lists organizations eligible to receive tax-deductible contributions and flags those that have been auto-revoked [3]. If your club isn't listed, or shows a revocation date, don't send letters claiming deductibility until that's resolved. You can still send a 'thank you for your gift' letter, just skip the 501(c)(3) language and the deduction claim. This is genuinely not a DIY legal judgment call in gray areas (fiscal sponsorship arrangements, umbrella exemptions under a parent PTA/PTO, group exemption numbers). If your club operates under a school district's umbrella exemption or a national booster organization's group exemption, confirm the exact language your donation letters should use with that parent organization and, where anything is unclear, with the IRS directly.
How does this connect to the rest of the treasurer's job?
Donation letters are one small piece of a bigger job. What does a treasurer do overall? Depositing funds, reconciling accounts, tracking restricted gifts (like a donation earmarked for uniforms only), preparing a board report, and filing the annual IRS return are all part of the same year-round cycle. Donation acknowledgment letters are really just the paperwork half of fundraising; the other half is making sure that money is tracked honestly once it lands in the account. A lot of new treasurers ask, 'what is a treasurer' really supposed to own versus what the board or the fundraising chair owns. The honest answer: the treasurer owns the money's accuracy and the filings, not necessarily every fundraising decision. But if a fundraising chair collects checks at a car wash and hands the treasurer a pile of donor names with no amounts recorded, the treasurer is the one who has to reconstruct it later for letters and for the 990. If you're setting this up from scratch (a brand-new booster club, or you inherited a mess from last year's outgoing treasurer with no templates at all), a state-specific starter kit can save real hours versus building every form and letter template from blank documents. BoosterLedger's $99 Treasurer Kit Builder puts together state-personalized versions of these letters and filing checklists in one pass, which is the kind of thing that's genuinely useful in month one and mostly irrelevant once you've built your own system.
What is Form 990 vs 990-N vs 990-EZ: which one does a booster club file?
| Filing | Who files it | Gross receipts threshold | Filing method | |
|---|---|---|---|---|
| Form 990-N (e-Postcard) | Smallest nonprofits | Normally $50,000 or less | Online only, via IRS e-Postcard system [4] | |
| Form 990-EZ | Mid-size nonprofits | Gross receipts under $200,000 AND total assets under $500,000 | Paper or e-file | |
| Form 990 (full) | Larger nonprofits | Gross receipts $200,000+ or assets $500,000+ | E-file required for most filers | Most booster clubs, PTOs, and youth sports groups fall into the 990-N category. It's a short online form, roughly eight pieces of information (EIN, tax year, legal name, address, confirmation of gross receipts under the threshold, and a statement the organization hasn't terminated) [4]. There's no financial detail to report on the 990-N itself, which is exactly why it's easy to forget: there's no dollar figure prompting anyone to sit down and do it.

Frequently asked questions
What does a treasurer do in a booster club?
A booster club treasurer tracks all incoming and outgoing money, reconciles the bank account, sends donor acknowledgment letters, prepares financial reports for the board, and files the club's annual IRS return (usually Form 990-N for small clubs). The role is about accuracy and recordkeeping more than fundraising strategy itself.
What is a treasurer responsible for besides writing donation letters?
Beyond donation letters, a treasurer handles deposits, expense payments, bank reconciliation, budget tracking, and the annual IRS filing. Many also manage cash-handling controls for events like concession stands and raffles, and hand off clean records to the next treasurer at year's end.
What is Form 990 and does a small booster club need to file it?
Form 990 is the IRS's annual information return for tax-exempt organizations. Small booster clubs with gross receipts normally $50,000 or less generally file the simplified Form 990-N e-Postcard instead of the full Form 990, per IRS guidance on annual exempt organization returns [4].
What is the 990 tax form used for?
It reports a nonprofit's revenue, expenses, and activities to the IRS each year, and it's publicly viewable. It lets the IRS and donors confirm the organization is still active and complying with exempt-status requirements. Missing it for three straight years triggers automatic revocation of tax-exempt status [2].
Do we need a donation letter for gifts under $250?
Not legally required by the IRS for the donor's deduction, but sending one anyway is good practice. IRS Publication 1771 requires written acknowledgment specifically for gifts of $250 or more; smaller gifts can rely on the donor's own bank record [1].
What has to be in a 501c3 donation acknowledgment letter?
The organization's legal name, a statement of 501(c)(3) status, the contribution amount or item description, the date received, and a disclosure of whether the donor received any goods or services in return (and their value, if so), per IRS Publication 1771 [1].
Can our booster club send donation letters if we're not sure our 501(c)(3) status is current?
Check the IRS Tax Exempt Organization Search first [3]. If your club has been auto-revoked for missing three years of 990 filings, you cannot honestly promise donors a tax deduction until status is reinstated. Don't guess; verify before sending any letter that claims deductibility.
What is the difference between Form 990-N and Form 990-EZ?
Form 990-N is a short online e-Postcard for organizations with gross receipts normally $50,000 or less. Form 990-EZ is a longer return for organizations with gross receipts under $200,000 and total assets under $500,000. Above those figures, the full Form 990 applies [4][5].
What happens if a donor received something in exchange for their gift?
You have to disclose the value of what they received and subtract it from the deductible amount, if the payment exceeds $75 and is partly a contribution. This is called a quid pro quo contribution disclosure requirement under IRS Publication 1771 [1].
What does a club treasurer do differently from a company bookkeeper?
A club treasurer typically works alone, unpaid, with less oversight and more turnover than a corporate finance team. That makes clear documentation, like donation letter logs and filing records, more important since the next volunteer treasurer has to pick up the system with little handoff time.
Is there a specific EIN requirement for donation letters?
The IRS doesn't require the EIN to appear on the letter for it to be a valid acknowledgment, but including it is standard practice. It helps donors' tax preparers verify the organization and signals the club is a properly registered entity, more than an informal parent group.
What is a treasurer of a club supposed to know about state charity registration?
Many states require nonprofits soliciting donations to register with a state charity office or attorney general before fundraising, separate from federal 501(c)(3) status. Requirements vary by state, so confirm registration rules with your state charity regulator directly before large fundraising campaigns or raffles.
