Tax form 990 explained: what booster treasurers must file

Last updated 2026-07-24

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 most people think of one, since exempt groups usually owe no federal income tax on money raised for their mission. Instead, it is a public accountability document: revenue, expenses, program activities, board members, and sometimes compensation, all laid out for anyone to see ^[1]. The IRS describes the 990 series as designed to give "the IRS and the public" a snapshot of the organization's finances and operations for the year ^[1]. That public part matters more than most new treasurers realize. Once filed, most 990s become searchable through the IRS Tax Exempt Organization Search tool and through sites like ProPublica's Nonprofit Explorer. Parents, school administrators, and league officials can and do look these up. For a booster club or PTO, the 990 is usually the only formal financial statement anyone outside the group ever sees. Treat it that way. If your numbers look sloppy or inconsistent from year to year, that's the first thing a skeptical parent or district administrator will notice. The 990 tax form family has three main versions for small nonprofits, covered in detail below.

What is the 990? (Which version do I actually file?)

Form 990-N (e-Postcard)	Organizations normally with gross receipts of $50,000 or less	Under $50,000 [2]
Form 990-EZ	Organizations with gross receipts under $200,000 and total assets under $500,000	Under $200,000 receipts / under $500,000 assets [3]
Form 990 (full)	Organizations with gross receipts of $200,000 or more, or total assets of $500,000 or more	$200,000+ or $500,000+ assets [3]	Most booster clubs and PTOs fall into the 990-N bucket. A concession stand, a few fundraisers, some uniform sales, and dues rarely push a small group past $50,000 in a year. But if your club runs a big annual gala, sells a lot of sponsorships, or holds a raffle with a large prize pool, check your total gross receipts (not net) against that $50,000 line every year. Gross means before expenses. A raffle that brought in $60,000 in ticket sales and paid out $20,000 in prizes still counts as $60,000 in gross receipts, not $40,000. The 990n is genuinely simple to file: it is done entirely online through the IRS's e-Postcard portal and asks for basic identifying information, confirmation you're still under the threshold, and a couple of yes/no questions [2]. It takes most treasurers under 15 minutes once they have the organization's EIN handy. The form 990-n has no paper option. If your predecessor treasurer tells you they mailed something in, be skeptical. That's not how this one works.

Which 990 you file depends almost entirely on your organization's gross receipts and total assets for the year, not on how big or small your mission is. The IRS sets three tiers for most small and mid-size exempt organizations. | Filing | Who files it | Gross receipts threshold |

What is a 990 tax form used for, exactly?

A 990 tax form does two jobs at once. First, it keeps your organization's tax-exempt status current with the IRS. Second, it creates a public record of how the group raised and spent money that year. For the full Form 990 and Form 990-EZ, the return asks for a statement of revenue and expenses, a balance sheet, a list of officers and directors, and a description of the organization's main program activities and accomplishments. Larger filers also answer governance questions: does the board review the 990 before it's filed, does the organization have a conflict-of-interest policy, that kind of thing. The 990-N e-Postcard is much thinner. It confirms your legal name, EIN, tax year, mailing address, website (if you have one), the name and address of a principal officer, and that your gross receipts are still $50,000 or less ^[2]. It does not report actual dollar figures at all, which is exactly why so many tiny organizations default to it without complaint. Even though the e-Postcard doesn't show your numbers to the public, your board and any parent group still deserves to see a real budget summary each year. The 990 filing is the compliance minimum, not a substitute for telling your own membership what happened with their kids' fundraising dollars.

What happens if a booster club or PTO doesn't file Form 990?

Miss three consecutive years of your required 990 filing and the IRS automatically revokes your organization's tax-exempt status. No warning letter with a countdown, no phone call. The statute is explicit: an organization that fails to file an annual return or notice for three consecutive years automatically loses its exempt status, effective the filing due date of the third year ^[4]. This is more common than most volunteer treasurers assume. IRS data has shown hundreds of thousands of small organizations losing exempt status this way since the rule took effect after the Pension Protection Act of 2006 ^[4]. Booster clubs and PTOs are especially vulnerable because they rotate volunteer treasurers every year or two, and the outgoing treasurer often doesn't hand off login credentials, filing history, or even a reminder that the group has a filing obligation at all. Once revoked, the organization is on the IRS's Auto-Revocation List, donations are no longer tax-deductible to donors, and depending on your state, your state charity registration or sales tax exemption can be affected too. Getting reinstated means filing Form 1023 or 1023-EZ again (with a fee) and, in many cases, filing the missed 990s retroactively ^[5]. It is fixable. It is also a real headache that eats weeks of volunteer time you'd rather spend on the actual booster program. If your group has already been auto-revoked, don't panic and don't guess at the fix yourself. Confirm the current reinstatement process and any streamlined procedures with the IRS directly, since the rules around retroactive reinstatement (including the Rev. Proc. 2014-11 procedures for small organizations) have specific eligibility windows ^[5].

When is Form 990 due?

Form 990, in any of its versions, is due on the 15th day of the 5th month after your organization's accounting period ends ^[3]. For a group running on a calendar year (January through December), that's May 15. For a group on a school-year fiscal calendar ending June 30, that's November 15. Extensions exist. Organizations can file Form 8868 to get an automatic 6-month extension ^[3]. That moves a May 15 deadline to November 15, for example. But an extension only pushes the filing due date. It doesn't change whether you needed to file in the first place, and it doesn't reset the three-year revocation clock. Mark this date on your board calendar the moment you take over as treasurer. New treasurers frequently discover the filing deadline only when a parent or the school's business office asks whether the club is "still a real nonprofit," which is usually a sign someone already got a letter or noticed the group on the revocation list.

What does a treasurer do? (The 990 is just one piece)

A treasurer's job covers a lot more ground than the annual tax filing, though the 990 is often the one deadline that actually has legal teeth. In practical terms, a treasurer keeps the books, tracks income and expenses across every fundraiser and program, reconciles the bank account monthly, prepares financial reports for board meetings, and makes sure the group's required government filings (IRS, state charity registration, and sometimes state sales tax) get done on time. At a booster club or PTO specifically, the treasurer usually also manages: cash handling from concession stands and gate admissions, deposit procedures so no single volunteer is alone with a cash box overnight, reimbursement requests from coaches or teachers, and the year-end handoff packet for whoever takes over next. Good treasurers write things down as they go. Great treasurers leave a paper trail so clean that the next volunteer doesn't have to guess where anything is. If you're asking "what does a treasurer do in a club" because you just got handed the job with zero notes from your predecessor, start with these four things: find the EIN, find last year's tax filing (or confirm none was ever filed), find the bank statements, and find out when the fiscal year ends. Everything else builds from those four facts.

What is a treasurer? What does a club treasurer do day to day?

A treasurer is the officer responsible for an organization's money: tracking it, reporting on it, and making sure the group stays financially honest and compliant with the law. In a volunteer booster club or PTO, the treasurer is usually an elected or appointed parent, not a professional accountant, doing the job on evenings and weekends between everything else in life. Day to day, a club treasurer's actual workload looks like this: - Recording every deposit and expense, ideally within a week of it happening, not months later from memory

• Reconciling the bank statement against the books every single month
• Preparing a simple income and expense report for board meetings
• Collecting receipts and W-9s from vendors or contractors paid over $600 (for potential 1099 filing)
• Filing the annual 990-series return by the deadline
• Renewing any state charitable solicitation registration or raffle license
• Keeping cash-handling controls in place: two people counting concession cash, deposits made promptly, no personal reimbursements paid from petty cash without receipts None of this requires an accounting degree. It requires consistency and a system you actually use. A shoebox of receipts from August doesn't help anyone in May when the 990 deadline hits.

What does a treasurer of a club do that a regular board member doesn't?

The difference between a treasurer and a general board member comes down to fiduciary responsibility for the money specifically. Every board member has a general duty of care to the organization, but the treasurer is the one who signs off on financial reports, catches discrepancies before they become a scandal, and is usually the person named as the organization's contact on IRS and state filings. That last point matters more than people expect. On a Form 990-EZ or full 990, the return asks for names of officers, and the principal officer or treasurer is frequently the point of contact for anything the IRS needs to follow up on ^[3]. If the IRS or your state charity office ever sends a letter, it often goes to whoever's name and address is on file, which might be a treasurer who left the role two years ago if nobody updated the records. This is exactly why handoffs matter so much for booster organizations, where the treasurer role turns over constantly. A clean handoff packet, a shared drive with filings and login credentials, and a written procedure for cash handling turns "what does a treasurer do" from a mystery into a checklist the next parent can actually follow.

Does a small booster club or PTO really need to file anything with the IRS?

Yes, almost certainly, if the organization is recognized as tax-exempt (or applied to be). Even the smallest booster club with a few thousand dollars a year in concession stand revenue is expected to file the 990-N e-Postcard annually if it has 501(c)(3) or other 501(c) status ^[1][2]. The one narrow exception: churches and certain church-affiliated organizations are not required to file an annual return, but a school booster club or general PTO does not qualify for that exception. If your group was never formally recognized as tax-exempt in the first place (no IRS determination letter, no EIN filed as an exempt org), the 990 filing requirement doesn't apply the same way, but that raises a different and arguably bigger problem: your group may be operating without the tax-exempt status parents assume it has, and donations to it aren't deductible. Confirm your organization's actual exempt status with the IRS's Tax Exempt Organization Search tool before assuming either way. If you're building or rebuilding a treasurer's record-keeping system from scratch, a state-personalized treasurer kit can save real time by pre-organizing the filing calendar, the cash-handling forms, and the state-specific charity registration steps you'd otherwise have to piece together yourself. It's a $99 one-time tool, not a substitute for actually reading your state's charity office guidance, but it beats starting from a blank spreadsheet.

What information does Form 990 (or 990-EZ) actually ask for?

The full 990 and the 990-EZ both ask for a mix of financial detail and governance detail, though the full 990 goes considerably deeper. Expect these categories on either version: total revenue broken down by source (contributions, program service revenue, fundraising events, gaming/raffles), total expenses by category (program, management, fundraising), a balance sheet showing assets and liabilities, a list of officers, directors, and key employees, and a section describing the organization's mission and program accomplishments for the year ^[3]. The full Form 990 adds more schedules depending on your activities. Schedule G, for instance, covers fundraising events and gaming, including raffles, which matters directly for booster clubs that run raffles as a major fundraiser ^[6]. If your gross receipts push you into full 990 territory because of a big raffle year, expect to itemize gross revenue, direct expenses, and net income from that raffle specifically. The 990-EZ is shorter but still requires an actual balance sheet and program service accomplishments section, unlike the 990-N which asks none of that. If your board has never seen an actual income statement or balance sheet, filing a 990-EZ for the first time is a good forcing function to build one, since you can't file it without one.

How does Form 990 relate to state raffle licensing and charity registration?

Form 990 is a federal filing with the IRS. It does not replace, and is not replaced by, any state-level requirement to register as a charitable organization or to hold a raffle license. These are separate systems that happen to ask for overlapping information. Most states require organizations that solicit charitable donations to register with a state charity official, often the attorney general's office or secretary of state, and many of these state registrations ask you to attach a copy of your most recent Form 990 as part of the annual renewal . If your group runs raffles, most states also require a separate raffle or gaming license, with its own application, its own fee, and its own reporting of proceeds, entirely apart from the IRS filing . Don't assume filing your 990-N with the IRS checks any state boxes. Confirm your specific state's charitable solicitation registration and raffle licensing requirements with your state's charity regulator or attorney general's office, since rules and thresholds vary widely and change over time.

Where can I check if my organization's 990 filings are current?

The IRS's Tax Exempt Organization Search tool lets anyone look up an organization's exempt status, see whether it's on the Auto-Revocation List, and pull copies of recently filed 990s ^[1]. This is the first place a new treasurer should check, before doing anything else. Search by name or EIN. If your organization shows up as "automatically revoked," that confirms the three-year lapse discussed above, and reinstatement is a real project involving Form 1023 or 1023-EZ and possibly the missed returns ^[5]. If it shows up as active and in good standing, pull the last filed 990 or 990-N confirmation and start your handoff binder from there. ProPublica's Nonprofit Explorer is a helpful public mirror of this same IRS data with a friendlier search interface, useful for a quick sanity check, though the official IRS search is the authoritative source for current status .

Frequently asked questions

What is Form 990 in simple terms?

Form 990 is the annual report a tax-exempt organization files with the IRS, showing revenue, expenses, and basic governance information. It replaces the income tax return that most for-profit businesses file, since exempt organizations usually don't owe federal income tax on mission-related revenue ^[1].

What is the 990-N and who has to file it?

Form 990-N, called the e-Postcard, is the simplest 990 filing, required for organizations whose gross receipts are normally $50,000 or less per year. It's filed entirely online, has no paper option, and asks only for basic identifying information, not financial detail ^[2].

What does a treasurer do?

A treasurer tracks an organization's income and expenses, reconciles bank accounts, prepares financial reports for the board, and handles required government filings like Form 990 and state charity registrations. In a booster club or PTO, this is usually a volunteer parent role, not a paid accountant.

What does a club treasurer do that's different from other board members?

The treasurer holds specific fiduciary responsibility for the organization's money: recording transactions, catching errors, signing financial reports, and often serving as the named contact on IRS and state filings. Other board members share general oversight duty but don't handle the books directly.

What happens if a booster club never files Form 990?

After three consecutive years of missing the required 990 filing, the IRS automatically revokes the organization's tax-exempt status, effective the third year's filing deadline, with no advance warning letter ^[4]. Reinstatement requires reapplying for exempt status and often filing the missed returns.

Does a small PTO with under $50,000 in revenue still need to file anything?

Yes. Organizations with gross receipts of $50,000 or less still must file the Form 990-N e-Postcard every year to keep their tax-exempt status active. There's no revenue floor below which the filing requirement disappears entirely ^[2].

What's the difference between Form 990-N, 990-EZ, and full Form 990?

The version depends on gross receipts and assets: 990-N for receipts under $50,000, 990-EZ for receipts under $200,000 and assets under $500,000, and the full Form 990 above those thresholds ^[2][3]. Higher tiers require more financial and governance detail.

When is Form 990 due each year?

Form 990, in any version, is due the 15th day of the 5th month after the organization's fiscal year ends. A calendar-year organization's deadline is May 15. An automatic 6-month extension is available by filing Form 8868 ^[3].

Can our raffle revenue push us into a higher 990 filing tier?

Yes. Raffle ticket sales count toward gross receipts at their full (gross) amount, not net of prizes paid out. A large annual raffle can push a small club from 990-N eligibility into 990-EZ or full 990 territory in that filing year.

Is Form 990 the same as a state charitable registration?

No. Form 990 is a federal IRS filing. Most states have a separate charitable solicitation registration, and many raffle-holding groups also need a separate state raffle license, both apart from the IRS filing. Confirm requirements with your state's charity office or attorney general ^[6].

What is a treasurer in a nonprofit club?

A treasurer is the officer responsible for managing an organization's finances: bookkeeping, reporting, banking, and compliance filings like the IRS Form 990. In volunteer organizations like booster clubs and PTOs, it's typically an elected parent volunteer, not a hired professional.

How do I check if my organization's tax-exempt status was revoked?

Search the IRS's Tax Exempt Organization Search tool by your organization's name or EIN. It shows current exempt status and flags organizations on the Auto-Revocation List, along with copies of recently filed 990s where available ^[1].

What does a treasurer do in a club with no accounting background?

You don't need an accounting degree, just consistency: record every transaction promptly, reconcile the bank account monthly, keep receipts organized, and know your filing deadlines. Many booster and PTO treasurers learn the role entirely on the job through handoff notes from the prior treasurer.
