TL;DR
Form 990 is the annual information return tax-exempt nonprofits file with the IRS. Which version you file (990-N, 990-EZ, or 990) depends on gross receipts and assets. Miss three years in a row and the IRS automatically revokes your tax-exempt status, no warning letter required.
What is Form 990?
Form 990 is the annual information return the IRS requires from most tax-exempt organizations, including 501(c)(3) charities, booster clubs, and PTOs. It's not a tax bill in the way your personal 1040 might generate one. It's a disclosure document. The IRS uses it to check that a tax-exempt group is still behaving like one, and the public can use it to see how a nonprofit spends its money. The IRS puts it plainly: tax-exempt organizations "generally must file an annual return" and the specific form depends on the organization's financial activity [1]. There isn't one single "990 form." There's a family of them, scaled to size. If your booster club or PTO has 501(c)(3) or other tax-exempt status, you're almost certainly required to file something every year, even if you took in zero dollars. That surprises a lot of new treasurers. "We're small, we probably don't have to file" is the single most expensive assumption in volunteer treasurer work, because the penalty for ignoring it isn't a fine. It's losing your tax-exempt status entirely. For background on the broader job this sits inside, see what a treasurer does day to day beyond just tax filings.
What is the 990 tax form actually used for?
The 990 tells the IRS and the public four things: how much money came in, how it was spent, who runs the organization, and whether the group is still operating within the rules of its tax-exempt category. Donors, grant committees, and watchdog sites like GuideStar/Candid pull data straight from these filings. Think of it as the nonprofit equivalent of a public company's annual report, except smaller nonprofits get a version that's genuinely simple to file. The IRS explicitly says the return is used "to provide the IRS with information required by the Internal Revenue Code" and to give the public information about the organization's finances and governance [1]. For a booster club, that mostly means reporting concession stand revenue, fundraiser proceeds, uniform or travel fees collected, and how much went to the team versus overhead. Nothing exotic. But it has to be accurate, and it has to be timely.
Which 990 does my booster club or PTO have to file?
| Gross receipts normally ≤ $50,000 | 990-N (e-Postcard) | |
|---|---|---|
| Gross receipts < $200,000 AND total assets < $500,000 | 990-EZ or full 990 | |
| Gross receipts ≥ $200,000 OR total assets ≥ $500,000 | Form 990 | |
| Private foundations (rare for booster/PTO groups) | 990-PF | Most booster clubs, PTOs, and youth sports associations land in the first row. If your annual concessions, spirit wear sales, and fundraiser income together stay under $50,000, you likely qualify for the 990-N, the shortest version there is. "Normally" is the IRS's word, and it matters. They average your receipts over the current year and the two prior years (or use a formula for orgs under three years old) rather than looking at just one bad or good year [3]. A single unusually strong car wash fundraiser year doesn't automatically knock you into 990-EZ territory. Confirm the exact averaging method with the IRS instructions or your state charity office, because the math has specific rules for organizations existing fewer than three tax years. |
The version you file depends on gross receipts and total assets, not on whether you "feel like" a small organization. Here's the breakdown from IRS guidance [2]: | Your group's situation | Form required |
What is Form 990-N and who can file it?
Form 990-N, nicknamed the e-Postcard, is the stripped-down filing for organizations with gross receipts normally $50,000 or less. It's filed entirely online through the IRS's own portal, takes about ten minutes, and asks for basic information: your EIN, legal name, address, and a confirmation that receipts are still under the threshold [3]. There's no financial detail required. No revenue breakdown, no expense categories. That's the whole appeal of it, and it's why most booster clubs and PTOs should be filing this one, not the longer forms. The catch: 990-N has no paper option and no extension. The IRS states the e-Postcard "is due every year by the 15th day of the 5th month after the close of your tax year" [3]. If your fiscal year ends June 30 (common for school-affiliated groups), that's a November 15 deadline. If you run on a calendar year, it's May 15. Read the full 990-N mechanics, including exactly what fields the portal asks for, before your first filing.
What happens if we miss a 990 filing?
One missed year usually isn't fatal. Three missed years in a row is. Section 6033(j) of the Internal Revenue Code requires the IRS to automatically revoke the tax-exempt status of any organization that fails to file its required return or notice for three consecutive years [4]. No hearing, no warning letter beforehand, no appeal process that reverses it retroactively. The revocation is automatic and effective as of the filing due date of the third year. This catches an enormous number of small nonprofits. Volunteer-run booster clubs and PTOs turn over treasurers every year or two, and if nobody hands off the filing responsibility cleanly, three years disappears fast. The IRS maintains a searchable Tax Exempt Organization Search tool where you can check your own group's status and see if a revocation already happened [5]. If you've been auto-revoked, you're not necessarily doomed, but you have real work ahead: reinstatement applications, possibly retroactive relief under Revenue Procedure 2014-11, and potentially back-filing returns. That's its own topic; see the specifics on [990](/articles/treasurer-basics/990) filing history and how reinstatement paths work depending on how long you've been off the rolls.
What is a treasurer?
A treasurer is the person responsible for an organization's money: tracking it, reporting on it, and making sure it's spent and recorded the way the bylaws and the law require. For a booster club, PTO, or youth sports group, that usually means one volunteer wearing a lot of hats at once. The treasurer isn't just a bookkeeper. They're often the only person in the organization who knows the group's tax-exempt filing deadline, whether the bank reconciliation matches, and whether a state raffle license needs renewing. Nobody else usually checks this work, which is exactly why financial controls matter so much in volunteer organizations. Two-signature check requirements, monthly board financial reports, and an annual outside review aren't bureaucratic overkill. They protect the treasurer as much as the organization, because an unreviewed set of books invites suspicion even when nothing went wrong.
What does a treasurer do day to day?
In a typical month, a booster club or PTO treasurer reconciles the bank statement, deposits cash from concessions or fundraisers, pays approved invoices, updates a simple ledger or spreadsheet, and reports a balance to the board. Around tax season, that expands to filing the 990-N (or whichever version applies) and, in many states, renewing a charitable solicitation registration or raffle license. A useful way to think about it: the treasurer is the connective tissue between fundraising activity and compliance obligations. Someone runs the concession stand or the wrapping paper sale; the treasurer has to turn that into a number the IRS and the board can trust. Concretely, the recurring job list looks like this: - Reconcile the bank account against receipts monthly
- Keep a running ledger of income and expenses by category
- File the annual 990-series return on time
- Track any state charitable registration or raffle license renewal dates
- Present a treasurer's report at board meetings
- Maintain records for at least the IRS's recommended retention period, generally three years for most tax records but longer for others [6]
- Hand off complete records to the next treasurer That last item gets skipped constantly, and it's the root cause of most auto-revocations. See 990 tax form basics for the filing side, and build a real handoff checklist before you rotate out.
What does a club treasurer do differently from a corporate one?
A club or booster treasurer works with volunteer labor, seasonal cash flow, and often no professional bookkeeping software, unlike a corporate treasurer who has staff and audited financials. The core duties (tracking money, reporting accurately, staying compliant) are the same. The resources to do it are not. Most booster club and PTO treasurers are parents doing this alongside a full-time job, with no accounting background and a shoebox or spreadsheet instead of QuickBooks. That's normal, and the IRS's 990-N system is deliberately built for exactly this reality: a ten-minute online form instead of a full tax return. Where club treasurers differ most is exposure to cash. A corporate treasurer rarely handles physical bills. A booster club treasurer counts a cash box after a Friday night football concession stand, which means cash-handling controls (two people counting together, deposit slips same night or next morning, no cash kept at someone's house) matter more here than almost anywhere else in nonprofit finance.
What does a treasurer do in a PTO or school-affiliated club?
PTO and school-affiliated club treasurers do everything a booster club treasurer does, plus they usually answer to both a parent board and, informally, school administration. That means an extra layer of reporting even though the legal filing obligations (990-series, state registration) are identical to any other 501(c)(3). Many PTOs are chartered under a state or national PTO/PTA umbrella organization, which sometimes changes the filing picture. Some national PTA affiliates file a group exemption return that covers local units; check with your state PTA office and confirm with the IRS whether your local unit is covered under a group ruling or must file independently. Don't assume you're covered just because a state or national PTA exists. Ask, and get it in writing.
When is the 990 due and can we get an extension?
The general due date for any 990-series return is the 15th day of the 5th month after your fiscal year ends [1][3]. Calendar-year organizations file by May 15. If your fiscal year runs July through June, common for school groups, the deadline is November 15. Extensions are available for the 990, 990-EZ, and 990-PF using Form 8868, which grants an automatic six-month extension . Form 990-N, the e-Postcard, has no extension option and accepts no paper substitute, because it's not really a "return" in the traditional sense, it's closer to a status confirmation. If you're going to miss the 990-N deadline, there's nothing to file for extension; just file it late as soon as you can, since a late 990-N doesn't itself trigger revocation, only three consecutive missed years does [4].
How do we know which 990 we filed last year, or if we filed at all?
Check the IRS Tax Exempt Organization Search tool, which lists an organization's determination letter, filed 990s, and revocation status if applicable [5]. This is the single fastest way for an incoming treasurer to figure out where the organization actually stands, rather than trusting whatever verbal history got passed down. Search by your organization's legal name or EIN. If your group shows up with a revocation date, you have work to do before anything else, including before applying for a state raffle license, because many state charity offices require current IRS tax-exempt status as a condition of registration.
What records do we need to keep to file the 990 accurately?
Keep bank statements, a reconciled ledger, receipts for major expenses, minutes of board meetings approving expenditures, and documentation of any grants or restricted donations. The IRS recommends keeping records supporting items on a return for at least three years from the filing date, though some records (like those related to real property or major equipment) should be kept longer [6]. For gross receipts calculations specifically, you'll need a running total of all revenue: membership dues, concessions, fundraiser proceeds, sponsorships, and any grants received, added together for the year, not netted against expenses. This is a common error. Gross receipts means gross, before you subtract what you spent on supplies or prizes.
Where do I actually go to file, and what does it cost?
Form 990-N files free through the IRS's own online system, accessible from the IRS's exempt organizations pages [3]. There's no third-party fee required to file it, though some commercial services charge for a guided version; you don't need to pay for that. Forms 990-EZ and 990 must be filed electronically as well, following the mandatory e-file requirements phased in under the Taxpayer First Act, and typically go through IRS-authorized e-file providers [1]. If your group is untangling a multi-year mess (a missed filing, a possible auto-revocation, a first-time raffle license application on top of it) a state-personalized reference built for your situation saves real hours versus piecing it together from twelve different IRS PDFs. That's the gap the BoosterLedger $99 State-Personalized Treasurer Kit is built to close: it maps your state's charity registration and raffle rules alongside the federal 990 requirements so a new treasurer isn't starting from a blank page. Check it out at boosterledger.com/treasurer-kit-builder if you want the shortcut. None of this is tax or legal advice, and no filing service can guarantee an outcome with the IRS; confirm specifics with the IRS and your state charity office before you rely on anything here.
Frequently asked questions
What is Form 990?
Form 990 is the annual information return most tax-exempt organizations, including 501(c)(3) booster clubs and PTOs, file with the IRS. It reports revenue, expenses, and governance information. It's public record, so donors and watchdog groups can see how a nonprofit spends its money. The version you file depends on gross receipts and total assets.
What is the 990 tax form used for?
It lets the IRS verify a tax-exempt organization is still operating within its exempt purpose, and it gives the public visibility into the group's finances. The IRS says it's used to meet Internal Revenue Code disclosure requirements and to inform donors and the public about the organization's activities and finances.
What does a treasurer do?
A treasurer tracks all incoming and outgoing money, reconciles bank accounts, reports finances to the board, and handles compliance filings like the annual 990-series return and any state raffle or charity registration renewal. In a volunteer nonprofit, one person usually does all of it with no professional staff support.
What does a club treasurer do differently from other treasurer roles?
A club or booster treasurer manages cash-heavy, seasonal income (concessions, fundraisers) with volunteer labor and limited tools, instead of the audited systems a corporate treasurer would have. The compliance duties are the same as any small nonprofit, but the day-to-day work involves a lot more physical cash handling and manual recordkeeping.
What happens if a booster club or PTO doesn't file its 990 for several years?
After three consecutive years of missing a required 990-series filing, the IRS automatically revokes the organization's tax-exempt status under Internal Revenue Code Section 6033(j). This happens without a warning letter or hearing. Reinstatement is possible but requires a formal application and often back-filing missed returns.
Do small booster clubs really have to file anything if they made almost no money?
Yes. If your organization has tax-exempt status, it must file some version of the 990 every year regardless of income, even if that's $0. Groups with gross receipts normally under $50,000 file the 990-N e-Postcard, which takes about ten minutes online and requires no financial detail.
How do I know if my nonprofit files a 990-N, 990-EZ, or full 990?
It depends on gross receipts and total assets. Under $50,000 in gross receipts normally qualifies for 990-N. Under $200,000 in receipts and under $500,000 in assets generally allows 990-EZ or full 990. At or above either threshold requires the full Form 990. Confirm your specific averaging calculation with IRS instructions.
When is the 990 due for a fiscal year that ends in June?
The due date is the 15th day of the 5th month after your fiscal year ends. For a June 30 fiscal year end, that's November 15. Calendar-year organizations (ending December 31) file by May 15 instead.
Can we get an extension on our 990 filing?
Forms 990, 990-EZ, and 990-PF can get an automatic six-month extension by filing Form 8868 before the original due date. Form 990-N, the e-Postcard, has no extension option since it isn't a traditional tax return; just file it as soon as possible if you're late.
How do we check if our nonprofit already lost its tax-exempt status?
Use the IRS Tax Exempt Organization Search tool, searchable by organization name or EIN. It shows determination letters, filed returns, and any automatic revocation date. This should be the first thing a new treasurer checks when taking over the books.
Is Form 990-N really free to file?
Yes. The IRS's own e-Postcard filing portal is free with no government fee. Some third-party services charge to file it for you or guide you through it, but that cost is optional, not required.
What does a treasurer of a club actually need to keep as records?
Bank statements, a reconciled ledger, receipts for expenses, board meeting minutes approving major spending, and documentation of grants or restricted funds. The IRS recommends keeping records supporting a filed return for at least three years, longer for property or equipment-related records.
Does a PTO chartered under a state or national PTA still have to file its own 990?
Not always independently; some national or state PTA affiliates file a group exemption return covering local units. Don't assume your unit is covered. Confirm directly with your state PTA office and the IRS whether your group is under a group ruling or needs to file on its own.
