TL;DR
Form 990 is the annual return most tax-exempt nonprofits file with the IRS. Which version you file (990-N, 990-EZ, or full 990) depends on gross receipts and assets. It's due the 15th day of the 5th month after your fiscal year ends. Miss three years in a row and the IRS automatically revokes your tax-exempt status, no warning letter required [1].
What is Form 990?
Form 990 is the annual information return the IRS requires from most tax-exempt organizations, including the 501(c)(3) booster club or PTO you just inherited the checkbook for. It is not a tax bill in the way a personal 1040 is. You are not sending money with it (mostly). You are telling the IRS and the public how much came in, how much went out, and who is running the place. 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, not optional, for almost every exempt org regardless of size. Here's the part new treasurers get wrong constantly: there is no dollar threshold under which you don't have to file anything. Even a booster club with $400 in the bank has to file something every year, usually the 990-N postcard. Skipping it because "we're too small to matter" is exactly how clubs end up on the IRS auto-revocation list three years later, scrambling to explain to parents why the group can no longer accept tax-deductible donations.
What does a treasurer do?
A treasurer is the person legally and practically responsible for tracking, reporting, and protecting an organization's money. In a booster club or PTO, that means keeping the checkbook (or online banking) reconciled, recording every deposit and expense, and making sure the group files whatever it owes the IRS and state every year. What do treasurers do day to day, in plain terms: they deposit fundraiser cash promptly, pay vendors and reimburse volunteers with a paper trail, keep a running ledger separate from anyone's personal Venmo, and report a budget-to-actual summary at meetings so the board isn't flying blind. What a treasurer does is less "accountant" and more "designated adult who can answer the question 'where did the money go' without guessing." What does a treasurer do in a club specifically, versus a corporate finance role? Scale and formality differ, but the job is the same shape: collect, record, safeguard, report. A $15,000-a-year cheer booster club and a $2 million PTA foundation both need someone tracking every dollar in and out; the booster club treasurer just does it with a spreadsheet and a shoebox of receipts instead of accounting software and a controller. Either way, filing Form 990 (in whichever version fits) sits squarely in the treasurer's job description, usually alongside 1099s, state charitable registration, and the annual budget presentation.
What does a club treasurer do that's different from a school PTO treasurer?
A club treasurer for a stand-alone booster club (say, a travel baseball team's parent group) usually has full financial control: their own EIN, their own bank account, their own 990 filing obligation. A PTO treasurer at a school often works inside a larger PTA/PTO structure that may have a state or national umbrella providing some bookkeeping templates, but the local unit still typically holds its own EIN and still files its own 990-series return separately from the school district's finances. What does a treasurer of a club do that a school business office doesn't already handle? Everything, basically. School districts do not file the booster club's taxes. The district's business office manages the school's own budget; your booster club or PTO, as a separate legal entity (usually a 501(c)(3)), is on its own for 990 filing, state raffle licenses, and sales tax questions. That separation surprises a lot of new treasurers who assumed "the school handles that." It doesn't.
Which version of Form 990 do I file: 990-N, 990-EZ, or full 990?
| $50,000 or less | any | Form 990-N (e-Postcard) | |
|---|---|---|---|
| Less than $200,000 | Less than $500,000 | Form 990-EZ (or full 990) | |
| $200,000 or more | $500,000 or more | Form 990 (full) | Source: IRS, "Annual exempt organization returns" filing thresholds [2]. Most booster clubs and PTOs live in the 990-N tier. The e-Postcard asks for basic identifying information (EIN, tax year, mailing address, confirmation you're still under $50,000) and takes maybe 10 minutes online through the IRS's e-Postcard filing system [3]. There is no paper version of the 990-N; it must be filed electronically. Once you cross $50,000 in average annual gross receipts, you graduate to Form 990-EZ or the full Form 990, depending on assets. Private foundations file a different form entirely (990-PF) regardless of size, though very few booster clubs are structured as private foundations. |
Which form you file depends on your organization's average annual gross receipts and total assets, not on how much cash is sitting in the account on filing day. The IRS sets three tiers, and picking the wrong one is one of the most common booster club mistakes. | Gross receipts (normally) | Total assets | Form required |
What is a 990 tax form actually asking for?
The full Form 990 runs 12 pages plus schedules and asks for a real accounting of the organization's year: total revenue by source (donations, program fundraisers, membership dues), total expenses by category, compensation of officers and highest-paid contractors, a balance sheet, and a governance section asking who's on the board and whether you have conflict-of-interest and whistleblower policies. Form 990-EZ is the same idea condensed to 4 pages: a summary income statement, a summary balance sheet, and shorter versions of the governance and compensation questions. Form 990-N (the e-Postcard) asks almost none of that; it just confirms you exist, you're still small, and you have a current address on file. All three versions, once filed, become public. The IRS makes 990s (and 990-EZs and 990-PFs) searchable through its Tax Exempt Organization Search tool [4], and third-party sites republish them. Anyone, including a skeptical parent or a rival booster club, can pull up your last three years of filings and see exactly what you reported. That transparency is by design, not a bug, and it's a good argument for keeping the numbers clean in the first place.
When is the 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 fiscal year ends. For a calendar-year filer (fiscal year ending December 31), that's May 15 [2]. For a fiscal year ending June 30, a common school-year cycle for booster clubs, the deadline is November 15. If you need more time, file Form 8868 to get an automatic 6-month extension. It's genuinely automatic; you don't need a reason, just the form filed by the original due date [5]. There is no extension available for Form 990-N; because it's just a confirmation postcard, the IRS doesn't offer (or need) an extension mechanism for it, though filing it a little late generally doesn't trigger penalties the way missing 990-EZ or full 990 deadlines can. Mark the date on whatever calendar your board actually looks at. "We meant to file it" is the single most common excuse the IRS hears right before a club discovers it's been auto-revoked.
What happens if we miss a 990 filing, or several?
One missed year usually isn't fatal by itself, though 990-EZ and full 990 filers can face late-filing penalties that accrue by the day. Miss three consecutive years, in any combination of 990-N, 990-EZ, or full 990, and the law is unforgiving: the IRS automatically revokes your tax-exempt status. No warning letter is required. The statute is explicit about this. Under Internal Revenue Code section 6033(j), "the exempt status of such organization... shall be revoked" if it fails to file for three consecutive years [6]. The IRS's own guidance repeats it plainly: organizations that don't file for three consecutive years "will automatically lose their tax-exempt status" [7]. Revocation means your donations are no longer tax-deductible to donors, you may owe corporate income tax going forward, and your organization's name shows up on the IRS's public Auto-Revocation List. Reinstatement is possible (there's a streamlined process for organizations that were eligible to file 990-N or 990-EZ, using Form 1023 or 1023-EZ and checking the retroactive reinstatement box, described in Revenue Procedure 2014-11) , but it costs a filing fee, takes real paperwork, and takes weeks to months depending on the backlog. Confirm current fees and processing times with the IRS before you budget for it.
How do I check if our organization has already been auto-revoked?
Search your organization's name or EIN on the IRS Tax Exempt Organization Search tool, which includes a specific Auto-Revocation List dataset [4]. If your booster club or PTO shows up there, your 501(c)(3) status is currently revoked, even if nobody told you and even if you're still collecting donations under the assumption you're tax-exempt. This is worth checking the day you take over as treasurer, before you do anything else. It's shockingly common for a club to lose status two treasurers ago, keep operating, keep collecting donations, and not find out until a parent asks for a donation receipt letter that the club legally can't provide anymore. Confirm your status directly with the IRS rather than trusting whatever the outgoing treasurer tells you; good intentions and accurate 990 history are not the same thing.
Do we need to file a state charity return too, or is the IRS 990 enough?
The federal 990 is separate from whatever your state requires. Many states require nonprofits, especially ones that fundraise from the public, to register with a state charity official (usually the attorney general's office or secretary of state) and file an annual report, sometimes with a copy of your federal 990 attached. Rules vary widely; some states exempt small organizations below a receipts threshold, others don't. Don't assume filing the 990-N with the IRS checks every box you need. Confirm with your state charity office or attorney general whether your booster club needs separate registration or renewal, especially if you run raffles, which often trigger a whole separate state raffle licensing requirement on top of everything else.
What records does a treasurer need to actually complete a 990?
You need a full year of bank statements, a reconciled ledger of income and expenses by category, a list of board members and officers with any compensation disclosed, and records of any grants or restricted donations received. If you paid any single contractor $600 or more, you also need to have issued a 1099-NEC, which ties into your 990's compensation reporting. If the outgoing treasurer handed you a shoebox instead of a clean ledger, rebuild the year from bank statements first; they're the one record nobody can lose or fudge after the fact. A properly reconciled checkbook (deposits matched to fundraiser totals, checks matched to invoices) makes filling out even the full Form 990 a few hours of work instead of a week of archaeology. This is exactly the gap a state-personalized treasurer kit is built to close: a one-time $99 setup that gives a new booster or PTO treasurer the state-specific filing checklist, ledger templates, and 990-tier decision guide instead of reinventing it from a stack of Google searches every August.
Can a volunteer treasurer really file the 990 themselves, or do we need an accountant?
For 990-N, absolutely, most volunteer treasurers file it themselves in under 15 minutes through the IRS's e-Postcard system, no accountant needed. For 990-EZ, a careful treasurer with clean books can often do it themselves too, though the governance and compensation questions trip people up. For the full Form 990 (once you're over $200,000 in receipts or $500,000 in assets), most booster clubs and PTOs bring in a CPA, at least for the first year or when the numbers get complicated with grants, restricted funds, or paid staff. That's a judgment call based on your organization's complexity and your board's comfort level, not a hard IRS requirement. This article and the tools referenced here are not tax or legal advice and don't guarantee any filing outcome or exempt status; when the numbers or the stakes get complicated, a real CPA or nonprofit attorney familiar with your state is worth the fee.
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 revenue, expenses, and governance details, and it's filed instead of a traditional income tax return since exempt organizations generally don't owe income tax. Which version (990-N, 990-EZ, or full 990) depends on your gross receipts and assets.
What does a treasurer do?
A treasurer tracks all money coming in and going out of an organization, keeps a reconciled ledger, deposits and safeguards cash, pays bills with a paper trail, and files required reports like Form 990 with the IRS. In a booster club or PTO, the treasurer is usually the one person who can answer exactly where every dollar went.
What is the 990 form used for?
It's used by the IRS to enforce accountability for tax-exempt organizations and by the public to see how a nonprofit spends its money. Filed 990s become public record, searchable through the IRS Tax Exempt Organization Search tool, so donors, parents, and watchdog groups can review an organization's finances and leadership.
What does a club treasurer do differently from a company treasurer?
The core job (record, safeguard, report) is the same, but a club treasurer is usually a volunteer managing a much smaller budget with fewer formal controls. They still need to file the correct 990-series form, track fundraiser cash carefully, and often handle state raffle licensing or charity registration on top of basic bookkeeping.
What is a 990 tax form, and is it really a tax form?
It's called a tax form but it's really an information return; most filers don't owe tax with it since they're tax-exempt. It reports income, expenses, and governance data to the IRS. The exception is unrelated business income, which can trigger actual tax owed on a separate form (990-T).
Which 990 form should our booster club file?
If average annual gross receipts are $50,000 or less, file Form 990-N (the e-Postcard). Between $50,000 and $200,000 in receipts (and under $500,000 in assets), file Form 990-EZ or the full 990. At $200,000+ in receipts or $500,000+ in assets, file the full Form 990. Confirm current thresholds directly with the IRS.
When is the 990 due each year?
The 15th day of the 5th month after your fiscal year ends. Calendar-year filers (year ending December 31) file by May 15. Fiscal-year filers ending June 30 file by November 15. An automatic 6-month extension is available for 990-EZ and full 990 using Form 8868; there's no extension mechanism for 990-N.
What happens if we miss three years of 990 filings?
The IRS automatically revokes your tax-exempt status under Internal Revenue Code section 6033(j), with no warning letter required. Your organization loses the ability to receive tax-deductible donations and appears on the IRS's public Auto-Revocation List. Reinstatement requires a new exemption application and, often, a filing fee.
How do I know if our organization already lost its tax-exempt status?
Search your organization's name or EIN in the IRS Tax Exempt Organization Search tool, which includes the Auto-Revocation List. Do this the day you take over as treasurer; clubs frequently keep operating and collecting donations for years after losing status without anyone realizing it.
Do we still need to file a 990 if we have no income this year?
Yes. There's no exception for a quiet year with zero activity. If you're recognized as tax-exempt, you file at least Form 990-N every year regardless of how much (or how little) money moved through the organization.
Is filing the IRS 990 the same as our state charity registration?
No, they're separate requirements. Many states require their own annual charity registration or report, sometimes with a copy of your federal 990 attached, through the attorney general's office or secretary of state. Confirm requirements with your specific state charity office since rules and thresholds vary widely.
Can a volunteer treasurer file Form 990 without hiring an accountant?
For 990-N, yes, it takes about 10 to 15 minutes through the IRS's online e-Postcard system. For 990-EZ, many organized treasurers manage it themselves with clean records. For the full Form 990, most clubs bring in a CPA at least for the first year, especially with grants or paid staff involved.
