TL;DR
Form 990 is the annual information return most tax-exempt nonprofits file with the IRS. 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 that most tax-exempt organizations file with the IRS instead of a corporate income tax return. It's not a bill. Exempt organizations generally don't owe income tax on money raised for their mission, so the 990 exists to show the IRS (and the public) what the group took in, spent, and holds, so everyone can check that a tax-exempt organization is still behaving like one. The IRS puts it plainly: "Form 990 is used by tax-exempt organizations, nonexempt charitable trusts, and section 527 political organizations 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 requires most exempt organizations to file something every year, even if the group has almost no money. For a small booster club or PTO, the practical version of this question is simpler: is this a tax form where you calculate what you owe? No. Is it a form where you skip a year because things were slow? Also no, and that second answer is the one that gets small nonprofits in trouble. Every exempt organization recognized under section 501(c) has an annual filing requirement unless it's specifically excused (churches and a few other narrow categories), and gross receipts under a few thousand dollars still means you file something [1]. For background on where this fits into your yearly calendar, see form 990.
What is the 990 tax form used for?
The 990 tells the IRS and the public three things: how much money came in, how it was spent, and whether the organization is still operating within the rules of its tax exemption. It's a transparency document as much as a compliance one. Most full Form 990 and 990-EZ filings become public record. GuideStar (now part of Candid) and the IRS itself publish them, so a donor, a school district, or a rival booster club can look up your group's finances. That's by design. The tradeoff for tax-exempt status is public accountability for how contributions get used. The form also asks about governance: does the board review executive compensation, does the organization have a conflict-of-interest policy, did it engage in political activity it shouldn't have. None of that applies much to a volunteer-run booster club with a five-person board and a $40,000 budget, but the questions are still there because the same form covers everything from a PTO to a university hospital system. A quick, honest note: filing a 990 doesn't grant you tax-exempt status and it doesn't confirm you have it. That's a separate process (Form 1023 or 1023-EZ for 501(c)(3) recognition). The 990 is the annual report you file once that status exists, or once you've told the IRS you're operating as an exempt organization.
Which version of Form 990 do I 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 | |
| Private foundations (any size) | Form 990-PF | "Gross receipts normally $50,000 or less" is the IRS's own threshold for who can file the simplest version, the 990-N [2]. Most booster clubs, small PTOs, and youth sports leagues land here. "Normally" matters: the IRS averages your receipts over the current and two prior years for a new-ish organization, so one unusually good fundraising year doesn't automatically bump you up if your average stays under the line [3]. If you're right at a threshold, err toward the more detailed form. The 990-EZ takes more work than the 990-N but it's still far short of the full 990's schedules. Groups that guess wrong and file the e-Postcard when they should have filed a 990-EZ can end up amending later, which is more annoying than just filing the right one the first time. For the specifics of the postcard version, see 990-n and form 990-n. |
Which 990 you file depends on your organization's gross receipts and total assets for the year, not on how big or small your group feels. Here's the breakdown from IRS guidance [2]: | Your situation | Form to file |
What is Form 990-N and who has to file it?
Form 990-N, nicknamed the e-Postcard, is the stripped-down annual filing for tax-exempt organizations whose gross receipts are normally $50,000 or less [2]. It's free, it's online-only, and it takes maybe ten minutes once you have the right login. You'll need eight pieces of information: your organization's legal name and any doing-business-as name, your EIN, your tax year, your mailing address, your website if you have one, the name and address of a principal officer, and a confirmation that gross receipts are still $50,000 or under, plus a statement if the organization has terminated [4]. That's it. No revenue detail, no expense breakdown, no balance sheet. The filing happens through the IRS's own portal, accessed via Login.gov, at the IRS website [4]. There used to be a separate third-party portal (the Urban Institute ran it for years); that's gone, and everything routes through IRS.gov now. If your organization has never filed before, you may need to call the IRS Exempt Organizations customer account line to get set up in their system before you can file electronically. The catch with the 990-N: because it's so easy, it's also easy to forget entirely, especially when a treasurer role turns over every year or two, which is normal for volunteer boards. Put the due date in writing somewhere that survives the handoff, more than in one person's calendar.
What happens if a nonprofit doesn't file Form 990 for three years?
Automatic revocation. No warning letter, no phone call, no grace period beyond the three years itself. The IRS states it directly: organizations that fail to file for three consecutive years "automatically lose their tax-exempt status" as of the filing due date of the third year [5]. This is the single most common way small nonprofits lose exemption, and it happens quietly. A booster club skips a year because the treasurer graduated with their kid and nobody picked up the filing. Then it happens again. By year three, the organization is on the IRS Auto-Revocation List before anyone notices, because nothing about the process announces itself along the way. Once revoked, the organization owes corporate income tax going forward, loses the ability to tell donors their gifts are tax-deductible, and often loses eligibility for state sales tax exemptions and grant applications that require proof of 501(c)(3) status. Reinstatement is possible but it's a real project: it usually means filing Form 1023 or 1023-EZ again, paying the filing fee (currently $275 for the 1023-EZ or $600 for the full 1023, though the IRS publishes current fees and these numbers do change) [6], and in some cases filing the back 990s you missed. The IRS does offer a streamlined path for organizations eligible to file 990-N or 990-EZ that apply within 15 months of their revocation date, which is the path most small booster clubs and PTOs qualify for [7]. Past that window it gets more paperwork-heavy. Either way, confirm current fees, forms, and deadlines with the IRS before you start, because these numbers move.
How do I check if my nonprofit's tax-exempt status has already been revoked?
Search the IRS Tax Exempt Organization Search tool at IRS.gov, which lets you look up any organization by name or EIN and see its current exemption status, including whether it's on the Auto-Revocation List [8]. This is free, takes under a minute, and is worth doing the first week you take over as treasurer, before you assume the paperwork trail from your predecessor is clean. If your organization shows up as revoked, don't panic and don't assume the group has to dissolve. Plenty of active, functioning booster clubs sit on that list for years without realizing it, still collecting donations they can no longer legally promise are tax-deductible. The fix is a reinstatement filing, not a shutdown. If your group is not on the list, that's good news, but it doesn't mean you're current. Being off the revocation list just means you haven't hit three consecutive missed years yet. Check your last filed return's tax year against your organization's normal fiscal year to make sure you're not one skipped filing away from trouble.
When is Form 990 due, and can I get an extension?
Form 990, in any version, is due on the 15th day of the 5th month after your organization's accounting period ends . For a nonprofit on a calendar year, that's May 15. For a group running on a school-year fiscal calendar ending June 30, that's November 15. A single automatic 6-month extension is available by filing Form 8868 before the original due date . That moves a calendar-year filer's deadline from May 15 to November 15. Form 990-N doesn't have an extension option because there's technically no penalty for filing it late, but a late 990-N still counts as a missed year if you never file it at all, and it still counts toward the three-year revocation clock if you skip it entirely. Write the due date on the actual fiscal year, not the calendar year, and make sure whoever holds the treasurer role next year inherits that date. This is the single easiest compliance item to lose in a volunteer board handoff, and it's also the one with the harshest penalty (full loss of exemption) for repeated neglect.
What does a treasurer do? (and how does 990 filing fit into the job)
A treasurer is the person on a nonprofit or club board responsible for tracking money in, money out, and making sure the group's financial obligations, including tax filings, actually get done. It's part bookkeeper, part compliance officer, part institutional memory for an organization that often has no paid staff at all. Day to day, what a treasurer does usually includes: keeping the checkbook or bank account reconciled, tracking income from dues, concessions, raffles, or sponsorships, paying vendors and reimbursing volunteers, preparing a budget or financial report for board meetings, and handing off clean records to the next person in the role. Filing the 990 (in whichever version applies) is one line on that list, but it's the one with legal teeth: miss it three years running and the whole organization's tax status disappears, more than the treasurer's to-do list. What does a club treasurer do that's different from a corporate one? Mostly scale, not substance. A club treasurer or booster club treasurer is doing the same core job (track money, report on it, keep obligations current) for an organization that might run entirely on volunteer hours and a shared spreadsheet, without an accountant on retainer. That makes the annual 990 filing genuinely more likely to fall through the cracks than it would at a larger nonprofit with paid finance staff, because there's no one checking the treasurer's work. What does a treasurer of a club do when there's no accountant at all? Usually everything: bookkeeping, budgeting, bank reconciliation, tax filing, and often training their own replacement a year or two later. That's a lot to hold in one volunteer's head, which is exactly why clear written procedures (what's due when, where the EIN and login info live, who the last three treasurers were) matter more for a five-person board than for a large staffed nonprofit.
What's the difference between the 990-N, 990-EZ, and full 990?
| Filing method | Online only | Paper or e-file | Paper or e-file | |
|---|---|---|---|---|
| Revenue/expense detail | None | Summary line items | Full schedules | |
| Balance sheet required | No | Simplified | Full | |
| Compensation disclosure | No | Limited | Detailed | |
| Public document | Yes | Yes | Yes | |
| Typical filer | Gross receipts ≤ $50,000 | Receipts < $200,000, assets < $500,000 | Receipts ≥ $200,000 or assets ≥ $500,000 | Source for thresholds: IRS, "Annual Exempt Organization Return: Who Must File" [2]. A lot of booster clubs cross from 990-N to 990-EZ territory the year they run a big capital campaign, a major raffle, or a one-time equipment fundraiser that pushes receipts over $50,000. That's not a penalty, it's just the next tier of paperwork. If your group is trending that direction, it's worth getting a bookkeeper or a CPA familiar with nonprofits to look at the 990-EZ once, even if you handle everything else yourself. For a broader comparison across all versions, see 990 tax form and irs form 990. |
The three forms differ mainly in how much financial detail they require, and that detail scales with your organization's size. Here's a side-by-side: | Feature | 990-N | 990-EZ | Full 990 |
Do small booster clubs and PTOs really have to file anything with the IRS?
Yes, almost always, and this is the part new treasurers most often get wrong. There's a common myth that if a booster club or PTO is small, informal, or doesn't have official 501(c)(3) paperwork, it doesn't need to file anything. That's not how the IRS treats it. If your organization has an EIN and has ever applied for or received recognition as tax-exempt, section 6033 requires an annual filing regardless of size, down to organizations with a few hundred dollars in the bank [1][2]. Even a booster club that's never formally incorporated, if it's operating as a nonprofit under a fiscal sponsor or has its own EIN, generally has some filing obligation, and skipping it doesn't make the requirement go away. It just runs the revocation clock. The organizations genuinely excused from filing are narrow: churches and certain church-affiliated organizations, and a handful of other statutory exceptions the IRS lists in its instructions [1]. "We're just a small booster club" is not one of the exceptions. If you're not sure whether your group has ever formally applied for exemption, that's a fair thing to figure out early, because it changes whether you're filing a 990-N or dealing with a different problem entirely (operating without recognized exempt status).
What should a new treasurer do in the first month on the job?
Pull the last three years of filings before you do anything else. Search your organization's EIN on the IRS Tax Exempt Organization Search tool to confirm current status and see what's actually been filed [8]. If nothing shows up for the last filed year, or the group appears on the Auto-Revocation List, that's priority one, ahead of budgeting, ahead of fundraising planning. Next, find the EIN itself, plus login credentials for the IRS 990-N filing portal if your group uses one, plus your state's charity registration account if your state requires separate registration (many do, run through the state Attorney General or Secretary of State's charity division; confirm with your state's charity office since requirements and fees vary widely by state). Write all of it down somewhere that isn't one person's email inbox, because the next treasurer will need it too. Then build a one-page calendar: fiscal year end, 990 due date, extension deadline if you use one, state registration renewal date, and any raffle or gaming license renewal if your group does raffles. This is the exact gap a lot of volunteer boards fall into, not because anyone is careless, but because the person who knew the deadlines left and nobody wrote it down. This is the kind of setup work a State-Personalized Treasurer Kit is built around: a one-time $99 packet mapped to your specific state's filing and registration requirements, so a brand-new volunteer treasurer isn't reconstructing this from scratch. It doesn't replace an accountant and it isn't tax advice, but it gives you the checklist and the calendar in one place.
What if my club has never filed a 990 at all?
That's more common than most new treasurers expect, especially for booster clubs that started informally, as a handful of parents pooling money for uniforms, and only later got an EIN or applied for exemption. If your organization has an EIN but you can't find any filing history on the IRS search tool, don't assume that means you're in the clear. First, confirm whether the group ever actually received 501(c)(3) or other exempt recognition, versus just having an EIN. An EIN alone doesn't make you tax-exempt; it's just a federal ID number, the same kind a business gets. If your group never filed Form 1023 or 1023-EZ and never got an IRS determination letter, you may be operating as a taxable entity without knowing it, which is a different conversation than a missed 990. If you do have confirmed exempt status but a filing gap, the honest move is to get current going forward and, if you're inside that 15-month reinstatement window from a revocation date, use the streamlined process [7]. Past that window, or if you're unsure which situation you're in, this is a case where paying a nonprofit-experienced CPA or attorney for a couple hours of advice is money well spent. This article, and BoosterLedger generally, isn't a substitute for that; treat everything here as a map of the terrain, not a filed return.
Frequently asked questions
What is a treasurer?
A treasurer is the officer on a nonprofit, club, or booster organization's board responsible for managing money: tracking income and expenses, keeping bank accounts reconciled, reporting finances to the board, and handling tax and compliance filings like Form 990. Most booster club and PTO treasurers are unpaid volunteers serving one- or two-year terms.
What does a treasurer do day to day?
Day to day, a treasurer reconciles bank statements, records income from dues or fundraisers, pays bills and reimburses volunteers, prepares financial reports for board meetings, and tracks upcoming deadlines like the annual Form 990 filing or state charity registration renewal. In smaller groups, one person often does all of it without paid staff support.
What is Form 990?
Form 990 is the annual information return the IRS requires most tax-exempt organizations to file under Internal Revenue Code section 6033. It reports revenue, expenses, and governance details rather than calculating owed tax, and versions of it (990-N, 990-EZ, full 990, 990-PF) scale in detail based on the organization's gross receipts and assets [1][2].
What is the 990 tax form used for?
It's used by the IRS and the public to check that a tax-exempt organization's finances match what its exemption allows: no improper private benefit, reasonable use of donated funds, and continued eligibility. Most versions become public record through the IRS and databases like Candid/GuideStar, so donors can review them too.
What does a club treasurer do differently from other treasurers?
A club or booster treasurer does the same core job, tracking money and meeting filing deadlines, but usually without paid accounting support, often on a one-year term with a full handoff to a new volunteer. That makes clear written records and a documented filing calendar more important than in staffed organizations.
Does a small PTO or booster club really need to file a 990?
Yes, in almost all cases. Section 6033 requires an annual filing for tax-exempt organizations regardless of size, with only narrow exceptions like churches [1]. A group with under $50,000 in gross receipts still files the simple Form 990-N postcard; it just doesn't file a detailed return.
What happens if we miss the 990 deadline one year?
Nothing immediate; there's no per-year penalty for the 990-N specifically, and other 990 versions can request a 6-month extension via Form 8868 filed before the original due date [9]. The real danger is missing three consecutive years, which triggers automatic revocation of tax-exempt status with no advance warning [5].
How do I know which version of Form 990 to file?
Check your organization's gross receipts and total assets for the year. Under $50,000 in gross receipts normally means Form 990-N; under $200,000 receipts and $500,000 assets generally allows Form 990-EZ; above either threshold requires the full Form 990 [2]. Private foundations file Form 990-PF regardless of size.
How do I check if our nonprofit status was automatically revoked?
Use the IRS Tax Exempt Organization Search tool at irs.gov, searching by your organization's name or EIN [8]. It shows current exemption status and flags organizations on the Auto-Revocation List. Check this within your first month as treasurer, since revocation happens quietly with no notice letter along the way.
Can a revoked nonprofit get its tax-exempt status back?
Yes, through reinstatement, usually by refiling Form 1023 or 1023-EZ and paying the filing fee. Organizations eligible for Form 990-N or 990-EZ can often use a streamlined process if they apply within 15 months of their revocation date [7]; confirm current fees and steps with the IRS.
Is Form 990-N really free and only ten minutes?
For most small organizations, yes. It requires eight basic items (EIN, legal name, address, tax year, principal officer, confirmation of gross receipts under $50,000, and a couple of others) filed through the IRS's online portal at no cost [4]. The time cost is mainly in remembering to do it every year.
Does filing a 990 mean we're officially tax-exempt?
No. Tax-exempt recognition comes from a separate application (Form 1023 or 1023-EZ) and an IRS determination letter. Form 990 is the annual report filed after that recognition exists; filing it doesn't create exempt status and skipping it doesn't remove status by itself, except through the three-year automatic revocation rule.
Where can I find our organization's past 990 filings?
Search the IRS Tax Exempt Organization Search tool [8] or a public database like Candid/GuideStar, both of which host filed 990s and 990-EZs (990-N e-Postcards show filing confirmation but minimal detail). This is worth doing before you assume a predecessor treasurer's filing history is complete.
