TL;DR
Almost every tax-exempt organization, including small booster clubs and PTOs, must file some version of Form 990 every year, even with $0 income. Groups under $50,000 in gross receipts file the free Form 990-N e-Postcard. Bigger groups file Form 990-EZ or the full Form 990. Miss three years running and the IRS automatically revokes your tax-exempt status.
What is Form 990?
| 990-N (e-Postcard) | Smallest orgs | Normally $50,000 or less [2] | |
|---|---|---|---|
| 990-EZ | Small/mid orgs | Gross receipts under $200,000 AND total assets under $500,000 [3] | |
| 990 (full) | Larger orgs | Gross receipts $200,000+ OR total assets $500,000+ [3] | |
| 990-PF | Private foundations | All private foundations, regardless of size [4] | Most volunteer-run booster clubs, PTOs, and small youth sports leagues land in the 990-N bucket. That's good news, because the 990-N takes about ten minutes and costs nothing. For the full background on how these forms relate to each other, see form 990 and irs form 990. |
Form 990 is the annual information return the IRS requires from most tax-exempt organizations. It is not an income tax return in the usual sense, because tax-exempt groups generally don't owe income tax, but the IRS still wants an annual accounting of what came in, what went out, who runs the place, and whether the organization is still doing what it said it would do when it applied for exemption. The IRS describes 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 actually creates the filing obligation, and Form 990 (in its various sizes) is how the IRS collects it. There isn't one single "990 tax form." There's a family of them, sized to the organization: | Form | Who files it | Gross receipts threshold |
What does a treasurer do (and why does 990 filing fall on them)?
A treasurer is the person responsible for an organization's money: tracking income and expenses, keeping bank accounts reconciled, presenting financial reports to the board, and making sure required filings actually get filed. In a small booster club or PTO, that last part, the filings, quietly becomes the treasurer's job by default, because nobody else on the board thinks to ask about it until a letter shows up from the IRS. What does a treasurer do in a club, concretely? Day to day: collect dues and fundraising cash, pay vendors and referees, keep receipts, maintain a checkbook or simple ledger, and report a balance at each meeting. Year to year: prepare or gather the numbers for the 990-N, 990-EZ, or 990, confirm the state charity registration is current if the group solicits donations, and hand over clean records at every officer transition. What do treasurers do that nobody else in the organization tends to do? They're usually the only person who knows the organization's EIN, its fiscal year end, and whether last year's 990 actually got filed. That knowledge gap is exactly how groups end up auto-revoked: the treasurer who knew the EIN graduated their kid out of the program, handed off a shoebox of receipts, and nobody told the new treasurer a filing was even required. What does a treasurer of a club do differently from a corporate bookkeeper? Scale and stakes are both smaller, but the compliance obligations are identical in kind. A $12,000-a-year booster club has the exact same 990-N requirement as a $12,000-a-year booster club three states over. The IRS doesn't grade on a curve for volunteer status.
Does a small booster club or PTO with almost no money still have to file?
Yes. If your organization is recognized as tax-exempt under section 501(c)(3) or most other 501(c) categories, you file something every year even if you took in $200 from a bake sale and spent $180 of it on supplies. The IRS is explicit that "most tax-exempt organizations that have annual gross receipts of $50,000 or less" must file the 990-N e-Postcard "unless they choose to file a complete Form 990 or Form 990-EZ instead" [2]. There is no filing-fee exception, no "too small to bother" exception, and no exception for being run entirely by volunteers. The only groups genuinely off the hook are certain church-related organizations and a few other narrow statutory exceptions the IRS lists on its exempt organization filing requirements page [5]. One wrinkle worth flagging: gross receipts, for this purpose, generally means total revenue before subtracting any expenses, not net profit. A raffle that brought in $60,000 in ticket sales but netted $15,000 after prizes probably pushes the club above the 990-N threshold and into 990-EZ territory, even though the group feels like it only "made" $15,000. Check the specific gross receipts test in the Form 990 instructions [3], and when in doubt, confirm with the IRS or a qualified preparer rather than guessing.
What is the 990-N e-Postcard and who qualifies?
The 990-N, often called the e-Postcard, is the stripped-down annual filing for organizations with $50,000 or less in gross receipts. It's filed entirely online through the IRS's Form 990-N electronic filing system, takes roughly eight required data points (EIN, tax year, legal name and address, other names the org uses, confirmation of gross receipts under $50,000, and a statement that the org hasn't terminated), and has no paper option [2]. There's no fee. There's also no dollar amount reported beyond the yes/no confirmation that receipts stayed under the threshold, which is part of why it's such a common source of missed filings: it feels too simple to be a real legal requirement, so treasurers assume someone else handles it, or that a group this small must be exempt from the exemption paperwork entirely. It isn't. See the dedicated pages on 990n and form 990-n for a walk-through of the actual submission screens.
What is Form 990-EZ and when do you need it instead of the e-Postcard?
Form 990-EZ is the mid-size return, for organizations with gross receipts under $200,000 and total assets under $500,000 at year end [3]. It's a real return, several pages, asking for a breakdown of revenue by source, program service accomplishments, officer and director listings, and compensation disclosures if applicable. A booster club that runs a big annual auction or a PTO that manages a $150,000 building fund campaign is a classic 990-EZ candidate. The form takes real bookkeeping to complete accurately, meaning a running ledger of income and expense categories through the year, not a shoebox reconstruction in March. Some states also use the federal 990-EZ (or full 990) as the base document for state charitable solicitation renewals, so getting this one right often saves a second round of work on the raffles-by-state side of compliance. Organizations can also choose to file the full Form 990 even if they qualify for the EZ or the e-Postcard. Some do this because a grantor or bank wants to see a fuller financial picture, or because their board wants more detailed record-keeping discipline. That's a legitimate choice, just not a required one below the thresholds.
What triggers the full Form 990, and what does it require?
The full Form 990 applies once gross receipts hit $200,000 or total assets hit $500,000, whichever comes first [3]. This is the long form: a governance section asking about board composition and conflict-of-interest policies, a detailed statement of functional expenses breaking spending into program, management, and fundraising categories, a list of the five highest-compensated employees or contractors over $100,000, and multiple supplemental schedules depending on the organization's activities. Most booster clubs and PTOs never get here, and if yours has, it's genuinely time to bring in a CPA who handles nonprofit returns regularly. The full 990 is public information once filed (more on that below), and a sloppy one is worse for the organization's credibility than no filing at all. This is not a form a volunteer treasurer should attempt solo for the first time without professional help; the goal here is understanding what applies to you, not preparing it yourself.
What is Form 990-PF and does it apply to a booster club?
Form 990-PF is for private foundations specifically, not public charities like most booster clubs, PTOs, and youth sports associations. Every organization classified as a private foundation must file the 990-PF regardless of size, with no small-org exception [4]. Private foundations are typically grant-making entities funded by a single family, company, or small group of donors, not membership organizations that run bake sales and car washes. If your booster club was set up as a standard 501(c)(3) public charity, which is the norm for these groups, 990-PF doesn't apply to you. If you're not sure how your organization was classified, check the IRS determination letter from when the group applied for exemption, or look up the organization in the IRS Tax Exempt Organization Search tool [6].
What happens if you miss a 990 filing, and what is auto-revocation?
Miss three consecutive years of required 990 filings (990-N, 990-EZ, 990, or 990-PF, in any combination) and the IRS automatically revokes the organization's tax-exempt status. This isn't a warning letter followed by a grace period; it's baked into the tax code. Section 6033(j) of the Internal Revenue Code provides that an organization "shall have its tax-exempt status revoked" if it fails to file the required return or notice for three consecutive years [7]. The IRS publishes the full list of auto-revoked organizations, and it's long. Booster clubs and PTOs show up on it constantly, almost always because of officer turnover: the treasurer who knew about the filing left, nobody told the replacement, and three years slipped by. You can search whether your organization has already been revoked using the IRS Tax Exempt Organization Search tool [6], which flags revocation status directly. Once revoked, the organization loses its exemption from federal income tax, donations to it are no longer tax-deductible to donors, and (depending on the state) it may also lose associated state tax exemptions or its standing to solicit charitable donations. Getting reinstated means filing Form 1023 or 1023-EZ again, sometimes with retroactive reinstatement available if you apply within 15 months of the revocation date and show reasonable cause [8]. It is a real headache, involves real paperwork, and can take several months. Prevention (just filing the e-Postcard every year, on time) is dramatically cheaper than the cure.
Is Form 990 public? Can anyone see our club's finances?
Yes, and this surprises a lot of first-time treasurers. Form 990, 990-EZ, and 990-PF filings are public documents. The IRS makes them available, and organizations like GuideStar/Candid republish them, meaning parents, donors, and honestly anyone with an internet connection can look up your booster club's reported revenue, expenses, and officer names. The 990-N e-Postcard is a narrower disclosure (mostly just confirming the org exists and stayed under the threshold) but it's also searchable through the IRS's exempt organization tools [6]. This is one more reason accurate, timely filing matters beyond just avoiding revocation: sloppy or wildly inconsistent numbers from year to year are visible to anyone who cares to look, including the next parent volunteer deciding whether to trust the books before taking over as treasurer. For a walk-through of how these public numbers get pulled together, see 990 tax form and [990](https://boosterledger.com/articles/treasurer-basics/990).
When is the 990 filing deadline for the 2022 and 2023 tax years?
Form 990, in any version, is due on the 15th day of the 5th month after the organization's accounting period ends. For a calendar-year organization (year ending December 31), that's May 15 of the following year [9]. So a calendar-year booster club's 2022 tax year return was due May 15, 2023, and its 2023 tax year return was due May 15, 2024. Many school-affiliated groups run a fiscal year that follows the school year instead, often July 1 to June 30. For those organizations, the deadline shifts to November 15. Check your organization's own IRS determination letter or prior filings to confirm which fiscal year it actually uses; this is a detail that gets lost fast during officer handoffs. A 6-month extension is available using Form 8868, which pushes a calendar-year filer's deadline to November 15 [10]. The extension is automatic (no explanation required) but it has to be filed by the original due date, not after. There's no extension available for the 990-N e-Postcard specifically, though the IRS Notice 2011-43 process (see reasonable cause reinstatement above) offers some relief if you've genuinely missed it.
Frequently asked questions
What does a treasurer do?
A treasurer manages an organization's money: tracking income and expenses, reconciling bank accounts, reporting balances to the board, and handling required government filings like Form 990. In small booster clubs and PTOs, the treasurer is usually the only officer who knows whether annual filings are current.
What is a treasurer?
A treasurer is the officer or volunteer responsible for an organization's finances: cash handling, bookkeeping, budgeting, and compliance filings. In nonprofit clubs, the role is usually unpaid and often held for just a year or two before handing off to the next parent volunteer.
What is Form 990?
Form 990 is the annual information return most tax-exempt organizations must file with the IRS under Internal Revenue Code section 6033. It reports revenue, expenses, governance, and program activities, and comes in several sizes (990-N, 990-EZ, 990, 990-PF) depending on the organization's finances.
What is a 990 tax form?
It's the IRS's annual disclosure form for tax-exempt organizations, not an income tax return in the traditional sense since exempt groups usually owe no income tax. It reports gross receipts, expenses, and leadership, and the smallest version (990-N) can be filed online in minutes with no fee.
What is the 990?
"The 990" usually refers to the whole family of IRS annual returns for tax-exempt organizations: 990-N for gross receipts under $50,000, 990-EZ for receipts under $200,000, the full 990 above that, and 990-PF for private foundations. Nearly every exempt group files one version every year.
Does our booster club have to file a 990 even if we made almost no money this year?
Yes. Nearly all 501(c)(3) organizations must file something annually regardless of income, even $0. Groups under $50,000 in gross receipts file the free 990-N e-Postcard. There's no minimum-income exemption from the filing requirement itself, only from which version you file.
What happens if our booster club missed three years of 990 filings?
The IRS automatically revokes tax-exempt status after three consecutive missed years, per Internal Revenue Code section 6033(j). You'd lose federal tax exemption and donors would lose the tax deduction for gifts. Reinstatement requires refiling Form 1023 or 1023-EZ, sometimes with retroactive relief if you act within 15 months and show reasonable cause.
How do I know which 990 form our organization should file?
Check gross receipts and total assets for the tax year. Under $50,000 gross receipts: file 990-N. Under $200,000 receipts and under $500,000 assets: file 990-EZ (or full 990 by choice). Above either threshold: file the full 990. Private foundations always file 990-PF regardless of size.
Is there a fee to file Form 990 or the 990-N?
No, there's no IRS filing fee for any version of Form 990, including the 990-N e-Postcard, 990-EZ, or full 990. Costs only arise if you hire a preparer or accountant to help complete the more detailed 990-EZ or full 990.
When is the 990 deadline for calendar-year organizations?
The 15th day of the 5th month after your fiscal year ends. For a calendar-year organization (year ending December 31), that's May 15 of the following year. A 6-month extension is available via Form 8868, filed by the original due date, moving the deadline to November 15.
Can anyone see our club's Form 990 once it's filed?
Yes. Form 990, 990-EZ, and 990-PF are public documents, viewable through the IRS's exempt organization search tools and sites like GuideStar/Candid. The 990-N e-Postcard discloses less detail but is also publicly searchable to confirm an organization's filing status.
What does a club treasurer do differently from a treasurer at a big nonprofit?
The core job is the same (track money, report to the board, keep filings current) but the scale and stakes differ. A club treasurer usually handles smaller sums with less formal bookkeeping software, and is far more often a short-term volunteer, which is exactly why filing knowledge tends to fall through the cracks at handoff.
How do I check if our organization has already been auto-revoked?
Search your organization's name or EIN in the IRS Tax Exempt Organization Search tool at irs.gov. It lists current exempt status and flags any organizations on the Auto-Revocation List. If you're listed, confirm next steps with the IRS before assuming your donors can still deduct gifts.
