TL;DR
Form 990 is the annual information return the IRS requires from most tax-exempt organizations, including booster clubs and PTOs. Which version you file (990-N, 990-EZ, 990, or 990-PF) depends on gross receipts and assets. Miss it three years running 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 uses to keep tabs on tax-exempt organizations. It's not a tax bill in the way a 1040 is. Most small nonprofits owe zero income tax. The 990 exists so the IRS, and the public, can see what money came in, what went out, and whether the organization is still doing what it said it would do when it applied for exempt status. 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 makes filing mandatory for almost every exempt group, not optional paperwork you can skip if you're small. Here's the part that trips up new booster club and PTO treasurers: there isn't one "990 form." There's a family of them, sized to your organization's money. A booster club raising $40,000 a year for uniforms and travel files something very different from a large national charity. Get the wrong version, or file nothing at all, and you're looking at automatic revocation of your tax-exempt status down the road. More on that below. If you just inherited the treasurer binder (or shoebox) and nobody told you a 990 was even a thing, you're not alone. This is one of the most common gaps we see in treasurer handoffs.
What does a treasurer do?
A treasurer tracks the money: what came in, what went out, what's left, and whether any of it needs to be reported to the IRS or the state. For a booster club or PTO, that means keeping a ledger, reconciling the bank statement every month, writing checks or approving reimbursements with backup receipts, and filing the group's annual 990 (or handing it to whoever does). It is more than "keeping the checkbook." A real treasurer job description usually covers four buckets: bookkeeping (recording transactions as they happen, not three months later), banking (reconciliation, signers, deposit procedures), compliance (990 filings, state charity registration renewals, sales tax exemption paperwork), and reporting (a monthly or quarterly summary to the board so nobody is surprised at the annual meeting). Many volunteer treasurers also handle cash from concessions stands, raffle ticket sales, or car washes, which brings its own set of controls (two people counting cash, deposit slips matching register tapes, that kind of thing). That's a separate topic from the 990, but it feeds the same numbers you'll eventually put on the form. If your group brought in over $50,000 last year, or has any paid staff, the treasurer job gets noticeably heavier. That's usually the point where groups start looking at a bookkeeper or at least a cleaner system, because doing it from memory in a notebook stops working.
What does a treasurer do in a club? (booster club and PTO specifics)
In a booster club or PTO, the treasurer does everything a general nonprofit treasurer does, plus some sport- or school-specific wrinkles. Concession stand cash needs a count sheet signed by two people before it hits the bank. Raffle ticket sales may need a state gaming or charity office license before you sell a single ticket (see state raffle licensing rules, which vary by state and change often, so confirm with your state's charity office). Spirit wear and fundraiser vendor payments need invoices on file, more than a Venmo screenshot. A lot of booster clubs and PTOs are set up as 501(c)(3) organizations, but some are 501(c)(4) or unincorporated associations that never formally applied for exemption. That status determines which 990 you file and whether donations to your group are even tax-deductible for donors. If nobody at your club can answer "are we a 501(c)(3)" with confidence, that's the first thing to nail down, not the 990 itself. A club treasurer also usually manages the transition when officers change each year or two. Bank signer updates, EIN documentation, prior years' 990s, and the state charity registration all need to move to the new treasurer cleanly. This handoff is where a shocking number of clubs lose track of filings entirely and end up auto-revoked without realizing it for two or three years.
Which version of Form 990 do you file?
| Gross receipts normally ≤ $50,000 | Form 990-N (e-Postcard) | |
|---|---|---|
| Gross receipts < $200,000 AND total assets < $500,000 | Form 990-EZ (or full 990) | |
| Gross receipts ≥ $200,000 OR total assets ≥ $500,000 | Form 990 (full) | |
| Private foundations (any size) | Form 990-PF | "Normally" matters in that first row. The IRS averages gross receipts over the current year and the two prior years for organizations under three years old, or uses a rolling average for established ones, to smooth out one unusually big fundraiser year. Confirm the exact averaging method on the IRS's site since the mechanics get technical. Most small booster clubs and PTOs land in the 990-N bucket. That's the good news: the 990-N is genuinely short, an online form with about eight data fields (EIN, tax year, legal name, mailing address, website if you have one, confirmation that receipts are under $50,000, and a statement the org hasn't terminated). It takes most treasurers under ten minutes once you have the EIN and basic info handy. Groups over $50,000 need the 990-EZ or full 990, which ask for actual financial statements, program descriptions, and sometimes a listing of officers' compensation. That's a real accounting task, not a form-fill, and it's where a lot of volunteer treasurers reasonably decide to hire a bookkeeper or CPA for that one filing. |
The version depends on your organization's gross receipts and total assets for the year. Here's the breakdown per current IRS guidance: | Organization's situation | Form to file |
What is the 990-N and who has to file it?
The 990-N (e-Postcard) is the electronic filing required from tax-exempt organizations whose gross receipts are normally $50,000 or less. It's filed entirely online through the IRS's Form 990-N Electronic Filing system, not mailed in, and there's no paper version [2]. The IRS states the 990-N requires organizations to provide: "Employer identification number (EIN)... Tax year; Legal name and mailing address; Any other names the organization uses; Name and address of a principal officer; Website address if the organization has one; Confirmation that the organization's annual gross receipts are normally $50,000 or less; If applicable, a statement that the organization has terminated or is terminating" [2]. There's no fee to file it, no attachments, and no financial statements required beyond the receipts confirmation. That's exactly why it exists: Congress and the IRS wanted small nonprofits to have some annual accountability without burying volunteer treasurers in bookkeeping requirements they can't realistically meet. One catch: filing the 990-N still requires an EIN. If your booster club has been operating for years on the school's tax ID or a coach's personal bank account (it happens more than you'd think), that's a separate problem to fix before you can file anything correctly.
What happens if you don't file a 990?
Miss three consecutive years and the IRS automatically revokes your tax-exempt status, no notice, no appeal period before it happens. This is not a slow bureaucratic process with warning letters. It's baked into the statute. The IRS explains: "Organizations that fail to file required Form 990-series returns or notices for three consecutive years will automatically lose their tax-exempt status. The revocation of the organization's tax-exempt status does not take place until the filing due date of the third year" [3]. That third missed year is the trigger point, and revocation is retroactive to that filing deadline. What that means in practice: if your club skipped filing for 2022, 2023, and 2024, your exemption is gone as of the 2024 filing deadline, whether or not anyone at the IRS or your club noticed. You'll find out (often the hard way) when a bank asks for a current determination letter, or when someone checks the IRS Tax Exempt Organization Search tool and sees "Auto-Revoked" next to your name [4]. Once revoked, any income the organization earns is potentially subject to federal income tax, and donors can no longer deduct their contributions. Getting reinstated means applying for exemption again (Form 1023 or 1023-EZ for many small groups), which costs a filing fee and takes real paperwork. For groups under $50,000 in gross receipts that self-certify eligibility, the IRS has a streamlined retroactive reinstatement process described in Revenue Procedure 2014-11, but it still requires filing the application and paying the user fee [5]. This is one of the more common disasters we hear about from incoming volunteer treasurers who inherited a club nobody had filed for in years.
When is Form 990 due?
Form 990, in any version, is due the 15th day of the 5th month after your organization's fiscal year ends. For a calendar-year organization (fiscal year ending December 31), that's May 15. If your booster club or PTO runs on a school-year fiscal calendar, say July 1 to June 30, your 990 is due November 15. Check your organization's bylaws or original IRS determination letter to confirm which fiscal year you actually use; a surprising number of clubs assume calendar year when their bylaws say otherwise. Extensions are available. Organizations can file Form 8868 to get an automatic six-month extension, per IRS instructions. That moves a May 15 deadline to November 15. It's a real form though, more than an email to the IRS, so don't assume you get extra time by doing nothing. Mark the deadline in whatever calendar your board actually uses, more than the treasurer's personal one. Deadlines missed because the only person who knew about them left the role is exactly how three-year auto-revocation streaks happen.
What does the public see on a 990?
Form 990 (the EZ and full versions especially) becomes public record once filed. Anyone can look up your organization's 990 filings through the IRS Tax Exempt Organization Search tool or third-party sites that republish them, like ProPublica's Nonprofit Explorer or GuideStar/Candid [4]. That means parents, donors, rival booster clubs, and local reporters can see your revenue, expenses, officer names, and (for the EZ/full versions) sometimes compensation figures. The 990-N doesn't disclose financial detail beyond the receipts threshold confirmation, which is one more reason small clubs generally don't mind filing it. This transparency cuts both ways. It's a legitimate accountability tool (a parent asking "can I see our 990" is asking a totally reasonable question), and it's also a reason to keep your bookkeeping clean before you file anything more detailed than the e-Postcard. Sloppy categorization on a public full 990 looks worse than sloppy categorization nobody ever sees.
990 vs 990-EZ vs 990-N vs 990-PF: how do they compare?
| Form | Who files it | Gross receipts / assets | Public financial detail | Filing method | |
|---|---|---|---|---|---|
| 990-N | Smallest exempt orgs | Receipts normally ≤ $50,000 | Minimal (name, EIN, receipts confirmation) | Online only, IRS e-Postcard system [2] | |
| 990-EZ | Small/mid exempt orgs | Receipts < $200,000 AND assets < $500,000 | Summary financials, program info | Electronic filing (paper phased out) | |
| 990 (full) | Larger exempt orgs | Receipts ≥ $200,000 OR assets ≥ $500,000 | Full financials, compensation, schedules | Electronic filing | |
| 990-PF | Private foundations | Any size | Full financials, required regardless of size | Electronic filing | Most booster clubs and PTOs start on the 990-N and stay there for years, sometimes their whole existence. If a big capital campaign or a large grant pushes you over $50,000 in a single year, check whether that pushes your "normal" average over the threshold too, since one big year doesn't automatically move you up a bracket. |
Does a small booster club or PTO really have to file anything?
Yes, almost always, if the group has 501(c) tax-exempt status. Section 6033 filing requirements apply regardless of size; the only variable is which version of the form applies [1]. There's no dollar threshold below which a recognized exempt organization is excused from filing entirely. The narrow exceptions are churches and certain church-affiliated organizations, which are not required to file 990s under IRC 6033(a)(3)(A). Booster clubs, PTOs, and youth sports organizations don't qualify for that exception; it's specific to religious organizations [1]. If your group has never applied for exempt status and is just operating informally under the school's umbrella or as an unincorporated association, the 990 requirement may not technically apply to you yet, but you also don't have the legal protections and donor deductibility that come with real 501(c)(3) status. That's a bigger structural question worth sorting out with your state's nonprofit filing office and, ideally, someone who actually does this for a living. This article and BoosterLedger's Treasurer Kit can point you toward the right forms and deadlines, but neither is a substitute for a CPA or attorney when your situation gets complicated.
How does a treasurer actually prepare to file the 990?
Start with the EIN. You cannot file any 990 without one, and it needs to match IRS records exactly, including the legal name on file. If you're not sure your club's EIN is correct or active, the IRS's own records (or a prior year's filed 990, if one exists) will confirm it. Next, pull together twelve months of bank statements and reconcile them against whatever ledger the club kept. For a 990-N, you mostly need the total gross receipts figure. For a 990-EZ or full 990, you'll need income broken out by source (membership dues, fundraiser revenue, concessions, donations) and expenses broken out by category (program costs, administrative, fundraising costs). Then confirm your fiscal year end and filing deadline, check whether the prior treasurer actually filed last year (don't assume; ask to see the confirmation email or accepted filing), and file through the appropriate IRS system before the deadline, or file Form 8868 for an extension if you need more time. If you're building this process from scratch because the last treasurer left no notes, that's common enough that we built a $99 State-Personalized Treasurer Kit specifically for this handoff moment: EIN lookup guidance, state-specific charity registration steps, and a 990 filing checklist matched to your state and organization type. It's not a substitute for a CPA once your finances get complicated, but it's built for exactly the "I just got handed a binder and a shoebox" situation.
What's the difference between the 990 and state-level filings?
Form 990 is a federal IRS filing. Most states also require separate registration and sometimes annual renewal with a state charity regulator, often housed in the Attorney General's office or Secretary of State, for organizations that solicit donations from the public. These are two entirely different filing systems, and doing one doesn't excuse you from the other. State charity registration requirements vary widely: some states exempt small organizations below a receipts threshold, some require audited financials above a certain size, and renewal cycles range from annual to every few years. There is no single federal standard here, so confirm the specifics with your state's charity office or Attorney General's nonprofit/charities division directly. Some states also link renewal to your federal 990 by requiring you to attach a copy of it to the state filing. That's one more reason to keep your federal 990 (even the simple 990-N confirmation) organized and accessible year over year, more than filed and forgotten.
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 income, expenses, and organizational activity so the IRS and public can confirm the group is still operating as a legitimate exempt organization. It's not an income tax bill; most filers owe nothing.
What is a 990 tax form?
It's the informational tax return exempt nonprofits file annually instead of a corporate income tax return. There are four versions (990-N, 990-EZ, 990, 990-PF), sized to the organization's gross receipts and assets. Booster clubs and PTOs usually file the simplest version, the 990-N, if receipts stay under $50,000.
What does a treasurer do?
A treasurer tracks all incoming and outgoing money for an organization: recording transactions, reconciling bank statements, managing reimbursements, and handling required IRS and state filings like the annual 990. In a volunteer nonprofit, the treasurer is usually the only officer who touches every financial detail across the year.
What is a treasurer?
A treasurer is the officer responsible for an organization's money: cash handling, bookkeeping, bank accounts, and compliance filings. In a booster club or PTO, it's typically an elected volunteer position, often held for one or two years before handing off to a successor.
What do treasurers do day to day?
Day to day, a treasurer records deposits and expenses, keeps receipts organized, reconciles the bank account monthly, and prepares a financial summary for board meetings. Around tax season, the job shifts to gathering annual totals for the 990 and confirming any state charity registration renewal is current.
What does a treasurer do in a club, specifically a booster club or PTO?
A club treasurer manages fundraiser cash (concessions, raffles, spirit wear), tracks dues and donations, pays vendors with documented invoices, and files the club's annual 990 and any required state charity registration. They also manage the officer handoff each year, transferring bank access, EIN records, and filing history to the next treasurer.
What does a club treasurer do differently from a corporate treasurer?
A club or PTO treasurer usually handles far more physical cash (concession stands, raffle tickets, bake sales) and works with much smaller budgets, often under $50,000 a year. That keeps most filing requirements simple (the 990-N), but cash-handling controls matter just as much, or more, because of how much money moves as physical cash.
Do small booster clubs really have to file a 990 every year?
Yes, if the club has recognized 501(c) tax-exempt status. Filing requirements under IRC section 6033 apply regardless of size; only the version of the form changes. Most small clubs file the free, online 990-N, which takes about ten minutes.
What happens if a nonprofit doesn't file Form 990 for three years?
The IRS automatically revokes the organization's tax-exempt status, effective as of the third year's filing deadline, with no advance warning notice required. Reinstatement requires reapplying for exempt status, which can take months and requires a new filing fee, even for small organizations using the streamlined process.
Which 990 form should a booster club file?
Most booster clubs with gross receipts normally at or below $50,000 file Form 990-N, the e-Postcard. If receipts exceed $50,000 but stay under $200,000 (and assets stay under $500,000), file Form 990-EZ. Larger organizations file the full Form 990.
When is the 990 due?
Form 990, in any version, is due the 15th day of the 5th month after the organization's fiscal year ends. For a calendar-year filer, that's May 15. A six-month extension is available by filing Form 8868 before the original deadline.
Is Form 990-N really free and online only?
Yes. The 990-N (e-Postcard) is filed entirely online through the IRS's electronic filing system, at no cost, with no paper option. It requires basic identifying information and confirmation that gross receipts are normally $50,000 or less; no financial statements are attached.
Can the public see a booster club's 990?
Yes, for the 990-EZ and full 990, financial details, program descriptions, and often officer information become public record, searchable through the IRS's Tax Exempt Organization Search tool or third-party sites. The 990-N discloses much less: mainly the organization's name, EIN, and confirmation of receipts under the threshold.
Is filing Form 990 the same as filing a state charity registration?
No, they're separate systems. Form 990 goes to the IRS. Many states also require charity registration or renewal through the Attorney General's office or Secretary of State for organizations soliciting public donations. Requirements and thresholds vary by state, so confirm specifics with your state's charity regulator.
