TL;DR
Almost every tax-exempt nonprofit, including small booster clubs and PTOs, must file some version of Form 990 every year, even with zero income. Groups under $50,000 in gross receipts file the free 990-N e-Postcard. Miss three years in a row and the IRS automatically revokes your tax-exempt status.
What is Form 990?
Form 990 is the annual information return that most tax-exempt organizations file with the IRS. It is not an income tax return in the way a Form 1040 is. Nonprofits generally don't owe federal income tax on money raised for their mission, but the IRS still wants an annual accounting of revenue, expenses, assets, and governance so it can confirm the organization still qualifies for exemption. The IRS puts it plainly: "Tax-exempt organizations, nonexempt charitable trusts, and section 527 political organizations file this form to provide the IRS with the information required by section 6033" [1]. That's the legal hook. Section 6033 of the Internal Revenue Code is what actually requires the filing, and Form 990 is how the IRS collects it. There are four versions, scaled to organization size: the 990-N (postcard), 990-EZ, full 990, and 990-PF for private foundations. A booster club or PTO with a $20,000 budget files a completely different form than a foundation with a $20 million endowment, but they're all under the same section 6033 rule. For a plain-language rundown of the form family, see our form 990 overview.
What is the 990 tax form, exactly, in booster club terms?
For a booster club, PTO, or youth sports league, think of the 990 as your organization's yearly report card to the IRS: here's what we raised, here's what we spent it on, here's who's in charge, and here's proof we're still operating as a nonprofit and not somebody's personal slush fund. You file it even if you had a rough year. You file it even if your bank balance barely moved. You file it even if all you did was run one concession stand and a car wash. The obligation is tied to your tax-exempt status, not to how much money crossed your hands. The one exception worth knowing: churches and certain church-affiliated organizations are not required to file, per IRS guidance on organizations not required to file [2]. Booster clubs, PTOs, and sports leagues don't get that exception. If you have a 501(c)(3) or you're an unincorporated association that's supposed to have one, you're on the hook.
Which 990 does my club actually file?
| Normally ≤ $50,000 | any | 990-N (e-Postcard) | |
|---|---|---|---|
| < $200,000 | < $500,000 | 990-EZ (or full 990) | |
| ≥ $200,000 | ≥ $500,000 | Form 990 | |
| Private foundations | any | 990-PF | These thresholds come straight from the IRS's own who-must-file guidance [3]. Most volunteer-run booster clubs and small PTOs land in the 990-N bucket. A concession stand, a few car washes, and a spring auction rarely add up to $50,000 in a given year, but plenty of bigger athletic boosters and district-wide PTOs cross into 990-EZ or full 990 territory, especially if they're holding a reserve fund or run a large raffle. One quirk: even if you qualify for the 990-N, you can voluntarily file a 990-EZ or full 990 instead. Some treasurers do this because a grant funder or bank wants to see a more detailed public filing. It's optional, not required. We cover the small-org version in detail in our 990-N and form 990-N guides, and the mid-size version in our 990 tax form explainer. |
The version you file depends on gross receipts and total assets, and the thresholds matter because filing the wrong form (or none) causes real headaches later. | Gross receipts | Total assets | Form required |
When is the 990 due?
Form 990, in any version, is due on the 15th day of the 5th month after your organization's accounting period ends. For a club running on a calendar year (January through December), that's May 15 of the following year [4]. If your fiscal year runs July through June, a common setup for school-affiliated groups, your deadline is November 15. You can get an automatic 6-month extension by filing Form 8868 before the original due date, per IRS instructions for that form [5]. That pushes a May 15 deadline to November 15. It's a simple form, no explanation required, and it costs nothing to file. If your treasurer handoff happened mid-year and nobody's sure what was filed last year, filing Form 8868 while you sort out the backlog is cheap insurance.
What happens if a booster club misses the deadline?
One missed 990-N carries no monetary penalty by itself; the e-Postcard doesn't have a late fee structure the way the EZ and full 990 do. But miss three years running, and the consequence is severe and automatic. Under Internal Revenue Code section 6033(j), an organization that fails to file its required return for three consecutive years automatically loses its tax-exempt status, no hearing, no warning letter required by statute. The IRS explains it directly: organizations that don't file for three consecutive years will have their exempt status revoked, and "the revocation is effective on the filing due date of the third annual return" [3]. This is exactly how so many small booster clubs and PTOs end up on the IRS's Auto-Revocation List without ever getting a notice that felt like a final warning. Treasurer turns over every year or two, records get lost in a shed or a spreadsheet nobody can find, and three 990-N postcards quietly go unfiled. For 990-EZ and full 990 filers, there are also daily late-filing penalties, generally $20 a day up to the lesser of $10,000 or 5% of gross receipts for smaller organizations, and higher for larger ones, under the penalty rules described in the Form 990 instructions [6]. In practice, the IRS often abates first-time penalties if you have reasonable cause and a clean compliance history, but you have to ask; it's not automatic.
How do I know if my club already lost its exempt status?
Check the IRS Tax Exempt Organization Search tool and look specifically at the Auto-Revocation List, which the IRS updates and makes searchable by name and EIN [7]. If your organization shows up there, your 501(c)(3) status was revoked as of the filing deadline for the third missed year, even if nobody at the club noticed at the time. This is a shockingly common discovery for new volunteer treasurers. You take over the books, go looking for last year's 990, and find nothing. Sometimes going back three or four treasurers, nothing. If that's you, don't panic and don't file the wrong form to fix it: the correction path is a formal Streamlined retroactive reinstatement (or standard reinstatement, depending on the size and gap) under Rev. Proc. 2014-11, more than filing a late 990-N. Reinstatement generally means filing Form 1023 or 1023-EZ again, checking the correct reinstatement box, and paying the user fee, currently $275 for Form 1023-EZ or $600 for the full Form 1023, per the IRS fee schedule . It is a real project, usually a few hours of paperwork if your records are decent, longer if they're not.
What does a treasurer do, generally?
A treasurer is the person responsible for a nonprofit's money and its paper trail: tracking income and expenses, keeping the bank reconciliations current, presenting financial reports to the board or membership, and making sure required filings (the 990 among them) actually get done on time. In a small booster club or PTO, the treasurer role often collapses into whoever's willing to do it, frequently a parent with no accounting background who inherited a shoebox of receipts and a login nobody wrote down. That's normal. It's also exactly why 990 deadlines get missed: the job passes hand to hand with no formal handoff process. At minimum, a treasurer should know the organization's EIN, its fiscal year end, whether it's currently in good standing with the IRS, and where last year's 990 (or 990-N confirmation) lives. If you can't answer those four things on day one of taking the job, that's your first task, not your fundraiser calendar.
What does a club treasurer do day to day, beyond the 990?
Day to day, a club treasurer of a booster club, PTO, or youth sports league handles a mix of routine bookkeeping and periodic compliance work. The 990 is one item on a longer list, not the whole job. Routine tasks: recording deposits and expenses, reconciling the bank statement monthly, collecting receipts for reimbursements, and keeping a simple ledger (spreadsheet is fine) that any board member could read without translation. Periodic tasks: preparing a treasurer's report for board meetings, helping plan the fundraiser calendar with realistic cash-handling controls (two people counting concession stand cash, sequentially numbered raffle tickets, that kind of thing), applying for or renewing a state charitable solicitation registration if required, and filing the annual 990 by the deadline. Handoff tasks: at year end or when a new treasurer takes over, documenting account logins, the EIN, the fiscal year, and the filing history so the next person doesn't start from zero. This is the single most-skipped step in volunteer treasurer roles, and it's the direct cause of most auto-revocations we see referenced in IRS guidance.
What is a treasurer, in one sentence, for a parent taking the job for the first time?
A treasurer is the volunteer (or occasionally paid) officer legally and practically responsible for tracking an organization's money, reporting on it honestly, and keeping the group compliant with tax filings like the 990 and any state charity registration. That's it. You don't need a finance degree. You need a system, a calendar with real deadlines on it, and the discipline to reconcile the bank account every month instead of once a year in a panic before the 990 is due. If you're building that system from scratch, our [990](/articles/treasurer-basics/990) hub walks through the whole filing landscape, and our irs form 990 page breaks down the line-by-line basics for first-timers.
Does a small booster club with almost no income still have to file?
Yes. This is the single most missed rule in the entire booster/PTO world. There's no minimum income exemption from filing; the $50,000 gross receipts figure sets which form you file (990-N versus 990-EZ), not whether you file at all. The IRS is explicit that "most tax-exempt organizations" have an annual filing requirement, and the small-organization threshold determines the version, not the obligation itself [3]. A booster club that raised $600 selling concessions still owes a 990-N. It takes about 10 minutes online through the IRS's e-Postcard filing system and it's free. The only broad exceptions are churches and certain church-integrated auxiliaries, per the IRS's list of organizations not required to file [2]. If your booster club isn't literally a church, assume you're required to file something.
What information does the 990-N actually require?
The 990-N is deliberately minimal. Per the IRS's own description, filers need: the organization's legal name and any doing-business-as name, mailing address, website (if any), EIN, name and address of a principal officer, tax year, confirmation that annual gross receipts are normally $50,000 or less, and a statement that the organization hasn't terminated . There's no financial detail required, no line-by-line revenue and expense breakdown. That's the tradeoff for staying under the $50,000 threshold. It's filed electronically through the IRS's e-Postcard system; there's no paper version. Compare that to the 990-EZ, which runs several pages and requires actual financial statements, a listing of officers and compensation, and program service accomplishments. If your club is bouncing between just-under and just-over $50,000 year to year, it's worth deciding in advance which form you're filing so you're not scrambling in April.
How does state charity registration interact with the 990?
Filing your federal 990 doesn't automatically satisfy state requirements. Many states require nonprofits, including booster clubs and PTOs that fundraise from the public, to register with a state charity official (often the Attorney General's office or Secretary of State) and file annual renewals, sometimes attaching a copy of the 990 itself. Requirements vary widely by state; some exempt small organizations below a revenue threshold, some don't exempt anyone. Confirm the specific registration and renewal rules with your state charity office or Attorney General's office directly, since thresholds and forms differ state to state and change periodically. If your club also runs raffles, most states layer a separate raffle or gaming license on top of general charity registration, with its own application and reporting cycle. Don't assume one filing covers the other; check both with the relevant state office before your event.
Frequently asked questions
What is Form 990?
Form 990 is the annual information return the IRS requires from most tax-exempt organizations under Internal Revenue Code section 6033. It reports revenue, expenses, assets, and governance details so the IRS can confirm the organization still qualifies for tax-exempt status. It is not an income tax return; most exempt nonprofits owe no federal income tax.
What is the 990 tax form used for?
It's used by the IRS to track whether a tax-exempt organization is still operating consistently with its exempt purpose and to give the public visibility into a nonprofit's finances. Four versions exist (990-N, 990-EZ, 990, 990-PF), scaled by organization size, so a small booster club and a large foundation file very different levels of detail.
What does a treasurer do?
A treasurer tracks an organization's money: recording income and expenses, reconciling bank accounts, reporting to the board, and handling required filings like the annual 990 and any state charity registration. In small volunteer groups, the treasurer is often the only person who touches the books, which makes documentation and handoff notes especially important.
What does a club treasurer do specifically for a booster club or PTO?
A booster club or PTO treasurer manages fundraiser cash handling, reconciles the bank account monthly, prepares treasurer's reports for meetings, files the annual 990 (usually the 990-N for smaller clubs), and maintains records of the EIN, fiscal year, and past filings so the club doesn't lose tax-exempt status through missed deadlines.
Does a small booster club with under $50,000 in income have to file anything?
Yes. Organizations with gross receipts normally at or below $50,000 file the 990-N e-Postcard, a free, roughly 10-minute online form through the IRS. There is no income minimum that eliminates the filing requirement entirely; the threshold only determines which version of the 990 applies.
What happens if my club misses three years of 990 filings?
Under Internal Revenue Code section 6033(j), missing three consecutive years automatically revokes tax-exempt status, effective on the filing due date of the third missed return, per IRS guidance. There's no warning notice required by law. Check the IRS Tax Exempt Organization Search auto-revocation list to see if this already happened to your organization.
How do I get my club's tax-exempt status back after auto-revocation?
You generally need to reapply for exemption using Form 1023 or Form 1023-EZ, checking the reinstatement box, and pay the applicable user fee (currently $275 for the EZ version or $600 for the full form, per IRS fee schedules). Depending on your situation, Rev. Proc. 2014-11 may allow retroactive reinstatement back to the revocation date.
When is Form 990 due?
The 15th day of the 5th month after your organization's fiscal year ends. Calendar-year filers (year ending December 31) are due May 15. You can get an automatic 6-month extension by filing Form 8868 before the original deadline, with no explanation required.
Is there a penalty for filing the 990 late?
The 990-N has no direct dollar penalty, but three consecutive missed years triggers automatic revocation. The 990-EZ and full 990 carry daily penalties, generally $20 per day up to the lesser of $10,000 or 5% of gross receipts for smaller organizations, per the Form 990 instructions, with higher caps for larger filers.
What is a treasurer of a club, in plain terms?
The treasurer is the officer responsible for the organization's money and financial recordkeeping: tracking cash in and out, reporting balances honestly to the group, and making sure required tax filings and registrations happen on schedule. It's a compliance role as much as a bookkeeping one.
Do churches have to file a 990?
No. Churches and certain church-affiliated organizations are on the IRS's list of organizations not required to file an annual return, even though most other tax-exempt groups, including booster clubs and PTOs, are required to file.
Can a booster club file a 990-EZ voluntarily even if it qualifies for the 990-N?
Yes. Filing a more detailed form than required is allowed. Some clubs do this because a bank, grant funder, or district office wants to see a fuller public financial picture than the minimal 990-N provides. It's optional, not a substitute obligation.
Does filing the federal 990 also cover state charity registration?
No. State charity registration, often through the Attorney General's office, is a separate requirement in most states and sometimes asks for a copy of the 990 as an attachment. Confirm registration and renewal rules with your specific state charity office, since requirements and thresholds vary by state.
