TL;DR
Form 990 is the annual information return the IRS requires from tax-exempt organizations. Most small booster clubs and PTOs file the simplest version, the 990-N postcard, if gross receipts are normally $50,000 or less. Bigger groups file Form 990-EZ or the full Form 990. Miss three years in a row and the IRS automatically revokes your tax-exempt status [1].
What is Form 990?
Form 990 is the annual information return that most tax-exempt organizations file with the IRS. It is not a bill. Your booster club or PTO almost certainly owes no income tax, but the IRS still wants an annual report showing what money came in, what went out, and who is running the place. The IRS describes it plainly: tax-exempt organizations, nonexempt charitable trusts, and section 527 political organizations file Form 990 "to provide the IRS with the information required by section 6033" [1]. Section 6033 of the Internal Revenue Code is the actual law that creates this filing duty. There isn't one single "990." There's a family of them, sized to the organization. A five-parent snack-bar fund and a multi-million-dollar regional charity both file "a 990," but they're filing very different forms. Which one you file depends almost entirely on your gross receipts and total assets for the year. If your group has a formal 501(c)(3) or 501(c)(4) exemption letter from the IRS, this filing requirement follows you every year going forward, even in a year with almost no activity. A year with zero fundraising still gets a 990-N. That surprises a lot of new treasurers.
What is the 990-N, and does my group qualify?
The 990-N, sometimes called the "e-Postcard," is the simplest version of the form. It's for small tax-exempt organizations whose annual gross receipts are normally $50,000 or less [2]. Most volunteer-run booster clubs, PTOs, and small youth sports leagues fall into this bucket. The IRS explains the eligibility rule this way: organizations may file the e-Postcard if their "annual gross receipts are normally $50,000 or less" [2]. "Normally" matters here, it's based on an average over your current year and the two years before it, not a hard cutoff on any single year. So one unusually good fundraiser year (a big raffle, a car wash boom) doesn't automatically bump you up if your three-year average is still under the threshold. The 990-N asks for almost nothing: your EIN, tax year, legal name and address, any other names you use, the name and address of a principal officer, your website if you have one, and a confirmation that gross receipts are still $50,000 or under [2]. There's no financial statement to attach. It's filed entirely online through the IRS's own portal, and it is genuinely a fifteen-minute job once you have your EIN and a login. The catch: there's no paper version and no extension for the 990-N. It's due the 15th day of the 5th month after your fiscal year ends [2], and if you miss it, you just miss it. You can still file it late (there's no dollar penalty for a late 990-N specifically), but three missed years in a row triggers automatic revocation, which we cover below. For the step-by-step filing walkthrough, see our 990-N guide and the shorter Form 990-N explainer.
What is Form 990-EZ, and who has to use it?
Form 990-EZ is the mid-size version, a genuine paper-and-numbers return, for organizations that outgrow the postcard but aren't big enough for the full form. Generally, you can use the 990-EZ if your gross receipts are less than $200,000 and your total assets are less than $500,000 at the end of the tax year [3]. Unlike the 990-N, the EZ actually asks for financial detail: a statement of revenue and expenses, a balance sheet, program service accomplishments, and information about compensation for officers and key employees. It runs about four pages plus schedules. A booster club that runs a concession stand, sells spirit wear, and hosts a golf tournament can cross the $50,000 threshold fast, especially once you count gross receipts (not net profit) from fundraisers. Gross receipts means the full amount taken in before subtracting expenses, so a raffle that grosses $60,000 and nets $20,000 in profit still counts as $60,000 for this test. Many treasurers get surprised by this distinction the first year they run a big raffle or tournament. If your board isn't sure whether you're still under the 990-N line, run the actual three-year average before assuming you're fine.
What is the full Form 990, and does a small booster club ever need it?
| 990-N (e-Postcard) | Normally $50,000 or less [2] | No asset test | 8 basic facts, filed online only | |
|---|---|---|---|---|
| 990-EZ | Under $200,000 | Under $500,000 [3] | Revenue/expense statement, balance sheet, schedules | |
| Full 990 | $200,000 or more, or | $500,000 or more [3] | Full financial detail, governance, compensation | Groups under the 990-N threshold can also voluntarily file the EZ or full 990 if they want more detailed public financials on record, but almost nobody does this by choice. It's more work for no real benefit at that size. |
The full Form 990 is a long, detailed return required once gross receipts hit $200,000 or more, or total assets hit $500,000 or more [3]. It runs eleven core pages plus a list of schedules covering everything from compensation to related organizations to lobbying activity. Most booster clubs, PTOs, and small youth sports groups never touch this version. It exists for larger nonprofits with paid staff, significant endowments, or multi-program operations. If your group somehow crosses into full-990 territory, a booster club that built a large capital reserve for a stadium project, for example, this is genuinely the point where you want a CPA who files nonprofit returns regularly. This isn't a DIY form. For comparison, here's how the three sizes stack up: | Form | Gross receipts threshold | Total assets threshold | What it requires |
What is a treasurer, and what does a treasurer do?
A treasurer is the officer responsible for an organization's money: tracking it, reporting it, and making sure it's handled honestly and legally. In a volunteer group like a booster club or PTO, the treasurer is usually the only person who fully understands the organization's finances at any given moment, which is exactly why the role matters so much. Day to day, what a treasurer does includes: keeping a checkbook or accounting software current, reconciling the bank statement every month, tracking income by fundraiser or program, paying approved bills, and reporting a clear financial summary at every board meeting. Nobody should be surprised by the bank balance at a meeting; if they are, the books have fallen behind. Annually, what a club treasurer does includes closing out the fiscal year, preparing a year-end financial report for the membership, handing off clean records to the next treasurer or to an audit committee, and filing the correct version of Form 990 by the deadline. That last item is the one new treasurers most often don't know about until it's almost too late, because nobody explicitly told them the exemption comes with an annual paperwork obligation attached. A treasurer of a club also usually manages internal controls: two signers on the bank account, receipts for cash handled at events, a second person counting money before it's deposited. None of this is about distrust. It's about protecting whoever holds the treasurer job next year from getting blamed for a shortfall they didn't cause. If you're brand new to the role, our what does a treasurer do overview and general treasurer duties breakdown are good starting points before you touch the 990 itself.
When is Form 990 due, and can I get an extension?
Form 990, in any of its versions, is due the 15th day of the 5th month after the end of your organization's accounting period [4]. For a group on a calendar fiscal year (ending December 31), that's May 15. For a group on a school-year fiscal year (ending June 30, which is common for PTOs and booster clubs), that's November 15. An automatic six-month extension is available for the 990-EZ and full 990 by filing Form 8868 before the original due date [4]. The 990-N has no extension option, because there's technically nothing to extend, it's an online confirmation, not a financial filing. Mark this date on a shared calendar the board can all see, more than in the treasurer's personal planner. Treasurer turnover is common in volunteer groups, and a filing deadline that lived only in one person's head is a filing deadline that gets missed the year they roll off the board.
What happens if we miss a 990 filing, or miss several years in a row?
One missed year usually isn't fatal. File late as soon as you catch it. But the IRS has a hard rule for repeated misses: an organization that fails to file a required 990, 990-EZ, or 990-N for three consecutive years automatically loses its tax-exempt status, by operation of law, with no separate notice or appeal process required before it happens [5]. The IRS states this directly: "Organizations that fail to file required Form 990-series returns for three consecutive years automatically lose their tax-exempt status" [5]. It's not a warning system where the IRS calls you before it happens. The revocation is automatic and retroactive to the filing due date of the third missed year. Once revoked, your organization is treated as a taxable entity going forward: donations are no longer tax-deductible to donors, and the group may owe income tax on revenue going forward until exemption is reinstated. For a group that relies on tax-deductible donations from parents and local businesses, this is a real, practical problem, more than a paperwork inconvenience. The good news: reinstatement is possible, and the IRS has a streamlined process for small organizations. See our full breakdown on irs form 990 for how that recovery process works, since it depends on how long you've been revoked and which form you'd normally file.
How do I know which Form 990 my group should file this year?
Start with your gross receipts for the current year, and average them against the prior two years. If that three-year average is $50,000 or less, you're almost certainly a 990-N filer [2]. If it's between $50,000 and $200,000 (and total assets stay under $500,000), you're in 990-EZ territory [3]. Above both those lines, you're looking at the full form and probably need paid help. A quick gut check: pull your last three years of bank deposits, add every fundraiser's gross intake (before expenses), add any grants or sponsorship income, and divide by three. That number tells you almost everything you need to know about which form applies. If your group is genuinely borderline, confirm with the IRS directly or with a CPA who works with nonprofits, rather than guessing. Filing the wrong form isn't usually penalized on its own, but filing an incomplete EZ or 990 when required, or skipping a required filing entirely, is what creates real risk.
Does every booster club or PTO actually need to file a 990?
If your organization has its own EIN and has received a 501(c)(3), 501(c)(4), or other IRS tax-exempt determination, yes, you almost certainly need to file some version of the 990 every year, even in a slow year with no fundraisers. The filing requirement is tied to your exempt status, not to how much money moved that particular year. A narrow exception exists for organizations that are formally part of a larger group exemption or that operate as an unincorporated arm of a school district without their own separate exemption. Some school-affiliated PTOs never got their own EIN and exemption at all; they just use the school's, and in that setup the school's own tax reporting may cover things differently. Churches and certain very small government-affiliated units have separate exceptions under the tax code, but a typical booster club, sports league, or parent-teacher group doesn't fall into those categories. Assume you have to file unless you can point to the specific reason you don't.
Does the 990 replace state charity registration or state tax filings?
No. The 990 is a federal IRS filing. Most states run a completely separate charitable solicitation registration system, often through the state Attorney General's office or Secretary of State, and many require their own annual report on top of whatever you send the IRS. Some states will accept a copy of your federal 990 as part of the state filing, but that's not universal, and the deadlines rarely line up with the IRS's May 15 / November 15 schedule. If your group solicits donations, sells raffle tickets, or runs a charity auction, confirm with your state's charity registration office or Attorney General's office what their specific annual filing requires, separate from anything you send the IRS. Don't assume filing your 990 checks every box. Plenty of well-meaning treasurers file a clean 990-N every year and still get a letter from their state because nobody registered the charity with the state in the first place.
What records does a treasurer need to actually complete a 990?
For a 990-N, you need almost nothing beyond your EIN, tax year dates, legal name and mailing address, any "doing business as" names, and the name of a principal officer [2]. It's fast because it asks for facts, not numbers. For a 990-EZ or full 990, you need real bookkeeping behind you: a complete income and expense ledger for the year, a balance sheet showing cash, any reserves, and any liabilities, and a list of board officers with their approximate time commitment. This is where a treasurer's month-to-month diligence pays off. If you've been reconciling the bank account monthly and tracking income by category all year, pulling together a 990-EZ is a few hours of work. If the books have been a shoebox of receipts, it's a multi-week scramble, and that's usually when boards start calling a CPA. This is also exactly the gap a State-Personalized Treasurer Kit is built to close: a one-time $99 setup that gives a new treasurer state-specific forms, a ledger template, and a filing calendar built around their actual fiscal year, so the 990 isn't a mystery assembled from memory in April.
What's the honest bottom line for a first-time treasurer?
Figure out your organization's exempt status and EIN first, then figure out your fiscal year end, then figure out your three-year average gross receipts. Those three facts tell you which 990 you file and when it's due. Put the due date on a shared calendar the whole board can see, more than your own phone. If you're taking over from a previous treasurer, ask directly whether the last three years of 990s were actually filed, don't assume. The IRS's own exempt organization search tool lets you look up an organization's filing history and current status for free [6], and it's worth five minutes to confirm your group isn't already sitting on a lapsed exemption from before you took the job. We're not a law firm or an accounting firm, and nothing here is tax or legal advice specific to your organization. When your situation is genuinely unclear, especially around revocation, reinstatement, or state registration, confirm with the IRS and your state charity office directly, or bring in a CPA who works with nonprofits regularly.
Frequently asked questions
What is a 990 tax form?
It's the annual information return the IRS requires from tax-exempt organizations, reporting income, expenses, and leadership information. It's not an income tax bill; most filers owe nothing. There are three main versions, 990-N, 990-EZ, and full 990, sized by gross receipts and total assets [1][2][3].
What is Form 990-N?
The 990-N, or e-Postcard, is the simplest 990 version, for organizations with gross receipts normally $50,000 or less. It's filed entirely online, asks for about eight basic facts, and has no dollar attachments required [2].
What does a treasurer do?
A treasurer tracks and reports an organization's money: keeping the ledger current, reconciling bank statements monthly, paying approved bills, reporting to the board, and filing required tax paperwork like the correct Form 990 each year. In a volunteer group, the treasurer is usually the sole person who fully understands the finances.
What is a treasurer of a club?
The treasurer is the elected or appointed officer legally and practically responsible for a club's finances: cash handling, bank reconciliation, budgeting, financial reporting to the board and membership, and annual tax filings. In small clubs it's often a volunteer parent or member, not a paid accountant.
What does a club treasurer do that's different from a regular member?
Unlike other members, the treasurer has signing authority on the bank account, keeps the official financial records, and is the person accountable if the IRS or state charity office has questions. Other officers may see summary reports, but the treasurer maintains the underlying detail.
What is the difference between Form 990, 990-EZ, and 990-N?
990-N is for organizations with gross receipts normally $50,000 or less. 990-EZ is for gross receipts under $200,000 and assets under $500,000. The full Form 990 is required once either gross receipts hit $200,000 or assets hit $500,000 [2][3].
When is the 990 due for a booster club or PTO?
The 15th day of the 5th month after your fiscal year ends. A calendar-year group's 990 is due May 15; a group on a July-June school-year cycle has a November 15 deadline [4]. The 990-N has no extension option; the EZ and full 990 can get a six-month extension via Form 8868.
What happens if we don't file a 990 for three years?
The IRS automatically revokes your tax-exempt status if you fail to file for three consecutive years, with no separate warning notice required [5]. Donations stop being tax-deductible and the group may owe income tax going forward until exemption is reinstated through the IRS's reinstatement process.
Does a small booster club really have to file anything with the IRS?
Yes, if your group has its own EIN and IRS tax-exempt determination, you must file some version of Form 990 every year, even in a year with almost no fundraising activity. The requirement is tied to your exempt status, not your activity level for that specific year.
How do I find out if our organization already lost its exempt status?
Use the IRS Tax Exempt Organization Search tool, which is free and shows filing history and current exemption status [6]. This is worth checking immediately when you take over as treasurer, since a lapsed status from before your term isn't automatically visible without looking it up.
Does filing a 990 replace state charity registration?
No. The 990 is a federal filing only. Most states have a separate charitable solicitation registration process through the Attorney General's office or Secretary of State, often with its own annual report and deadline. Confirm requirements with your specific state charity office.
Can a volunteer treasurer file Form 990 without a CPA?
For the 990-N, yes, it's designed for volunteers and takes about fifteen minutes online. The 990-EZ is doable for a treasurer comfortable with basic bookkeeping. The full Form 990 usually calls for professional help given its length and complexity.
