TL;DR
Form 990-N is due every year by the 15th day of the 5th month after your organization's fiscal year ends. For a calendar-year booster club (year ending December 31), that's May 15. Miss the deadline and nothing happens immediately, but miss it three years in a row and the IRS automatically revokes your tax-exempt status. There's no extension form for the 990-N, though late filing has no direct penalty.
When is the 990-N deadline?
The 990-N (the "e-postcard") is due by the 15th day of the 5th month after the end of your organization's accounting period. Most booster clubs, PTOs, and youth sports groups run on a calendar year, so their deadline is May 15 for the prior year's filing. If your group's fiscal year ends June 30 instead (common for school-affiliated boosters), your 990-N is due November 15. The IRS states it plainly: organizations "whose annual gross receipts are normally $50,000 or less" must file the e-Postcard "unless they choose to file a complete Form 990 or Form 990-EZ instead" and the form is due "by the 15th day of the 5th month after the close of your tax year" [1]. There's no paper version and no fee to file. If May 15 lands on a weekend or federal holiday, the 990-N portal still generally holds to the actual calendar date rather than shifting to the next business day, so don't assume you get extra time. When in doubt, confirm your specific due date with the IRS Tax Exempt Organization Search tool or by calling the IRS Exempt Organizations customer account line at the number listed in the instructions for Form 990 [2].
What happens if you file the 990-N late?
Nothing happens the first time. There's no monetary penalty for filing Form 990-N late, unlike the 990 or 990-EZ which can carry daily penalties for large organizations. The IRS confirms there's no penalty assessed for a late 990-N [1]. That's the good news. The bad news: the IRS doesn't send reminder notices before the deadline, and it doesn't track "late" filings individually the way it does for full-form filers. What it does track is a streak. File nothing (990-N, 990-EZ, or 990) for three consecutive years and your exempt status is automatically revoked by law, no warning letter required beforehand under the statute itself, though the IRS does typically send reminder notices to the last address on file before that third year lapses. So the real deadline pressure isn't May 15 this year. It's whether your predecessor treasurer filed last year and the year before. If you're new to the books and don't know, that's the first thing to check before you worry about anything else.
What is the three-year auto-revocation rule?
Section 6033(j) of the Internal Revenue Code requires the IRS to revoke the tax-exempt status of any organization that fails to file a required annual return or notice for three consecutive years. The statute says exempt status "shall be revoked" as of the filing due date of the third year, automatically, with no separate proceeding [3]. This isn't discretionary on the IRS's part. It's the law. The IRS maintains a public Auto-Revocation List and an Exempt Organizations Business Master File you can search to check whether a specific EIN has been revoked [4]. If your organization shows up there, its 501(c)(3) or 501(c) status is gone, retroactive to the original filing deadline of that third missed year, not the date you discover the problem. This matters more for small booster clubs than people expect, because small organizations under the $50,000 gross receipts threshold are exactly the ones eligible to file the simple 990-N, and they're also the ones most likely to go a few years with an inattentive or rotating volunteer treasurer who never knew filing was required at all.
How do I know if my organization already got auto-revoked?
Search your organization's name or EIN on the IRS Tax Exempt Organization Search tool, which includes the Auto-Revocation List and shows the effective revocation date if applicable [4]. This takes about two minutes and should be step one for any new treasurer, before you even open the checkbook. If you're listed, your organization is currently NOT tax-exempt for federal income tax purposes, even if your bylaws still say 501(c)(3) and even if your bank account is still open under the old EIN. That gap matters for donors: contributions made while an organization is revoked generally aren't deductible to the donor, and the organization itself may owe corporate income tax on revenue earned during the revoked period. If revoked, you'll typically need to reapply using Form 1023 (or 1023-EZ if you qualify) and, for organizations that had gross receipts under $50,000, the IRS has a streamlined retroactive reinstatement process described in Revenue Procedure 2014-11, provided you apply within 15 months of the revocation date and haven't been revoked before [5]. Confirm current eligibility and forms with the IRS, since fee amounts and form editions change.
What is Form 990, and how is it different from the 990-N?
Form 990 is the IRS's annual information return for tax-exempt organizations. It's the full-length version: financial statements, program descriptions, board and officer compensation, governance policies. Larger nonprofits file the full Form 990; mid-size organizations (generally gross receipts under $200,000 and total assets under $500,000) can file the shorter Form 990-EZ instead [6]. Form 990-N is the stripped-down version for the smallest organizations, those with gross receipts normally $50,000 or less. It's eight data fields online: EIN, tax year, legal name, mailing address, website if you have one, confirmation your gross receipts are still under the threshold, and a statement that the organization hasn't terminated [1]. No financial statements, no attachments, nothing to mail. Every 501(c)(3) is required to file one of these three every year (990, 990-EZ, or 990-N) based on its revenue and asset size. There's no exemption from filing based on being small, only an exemption from filing the long form. If you're unsure which one your booster club should be using, our overview of Form 990 and the specific breakdown at 990-N walk through the thresholds in more detail.
What is the 990 tax form used for?
The 990 tax form exists so the IRS and the public can see how a tax-exempt organization raises and spends money, without the organization paying corporate income tax on that activity. It's an information return, not a tax bill. Most 501(c)(3) organizations file some version of it annually, and the IRS makes completed 990s (not 990-Ns, which have no financial data) publicly searchable [1]. For a small booster club, the practical purpose is narrower but still real: filing keeps your exempt status alive. Donors, school districts, and sometimes even your own bank may ask to see a copy of your most recent 990 or confirmation of your exempt status before writing a check or opening an account. Candid's GuideStar service and the IRS's own search tool pull data straight from these filings, so a lapsed or missing filing history is visible to anyone who looks. Our explainer on the 990 tax form covers what's actually reported on the full version if your group has grown past the 990-N threshold.
What does a treasurer do?
A treasurer keeps the organization's money organized, accounted for, and reported on time. For a booster club, PTO, or youth sports group, that means tracking income (concessions, membership dues, sponsorships, fundraisers), tracking expenses (uniforms, equipment, tournament fees, insurance), reconciling the bank account monthly, and making sure required filings, like the 990-N, actually get submitted every year. It's not a bookkeeping-only role in most small nonprofits. The treasurer usually reports financial status at every board meeting, flags cash-flow problems before they become crises, and is often the person who signs checks or approves reimbursements alongside another officer for basic internal control. Depending on your bylaws, the treasurer may also prepare or review the annual budget and help the board understand what it can and can't afford to spend on the next season.
What is a treasurer, exactly, and what do treasurers do day to day?
A treasurer is the officer (usually elected or appointed under the organization's bylaws) legally and practically responsible for its finances. In a volunteer-run booster club, that's rarely a full-time job description; it's a few hours a month most of the year, then a much heavier lift during fundraiser season and at fiscal year-end. Day to day, treasurers do things like: deposit checks and cash from concessions or events, categorize expenses in a spreadsheet or accounting tool, pay vendor invoices, collect receipts for reimbursement requests, and keep a simple ledger current enough that anyone could open it and understand the group's financial position in five minutes. Around fiscal year-end, the job shifts to filing the 990-N (or handing records to whoever prepares the 990-EZ), preparing for handoff to the next treasurer, and making sure state charitable registration, if your state requires it, is current too.
What does a club treasurer do differently from a corporate one?
A club treasurer, whether for a booster club, PTO, or rec league team, operates at a much smaller scale and with far less formal infrastructure than a corporate treasurer, but the core responsibilities rhyme: safeguard the money, report accurately, don't let one person control both the books and the bank account unchecked. What's different is the stakes are personal and community-facing rather than shareholder-facing. If a club treasurer loses track of a $3,000 fundraiser or misses the 990-N deadline three years running, there's no compliance department to catch it. It's on the volunteer, and often the consequences (lost tax-exempt status, an awkward parent-meeting conversation about missing raffle proceeds) land directly on the next person who takes the job. That's why the paper trail matters so much more, proportionally, in a small club than in a big organization: there's no backup system if the treasurer's laptop dies or the treasurer just quits mid-season.
What does a treasurer do in a club with no accounting background?
Most volunteer treasurers have no accounting training, and that's normal, not a red flag. The job doesn't require a CPA. It requires consistency: recording every transaction close to when it happens, keeping receipts, and reconciling the bank statement every month rather than trying to reconstruct a year of activity in April. A few habits go a long way. Use a dedicated bank account for the organization, never a personal one. Require two signatures or two-person approval for anything over a set dollar threshold your board picks. Keep a simple running ledger (even a spreadsheet is fine for an organization under the $50,000 990-N threshold) with date, description, amount, and category for every transaction. And calendar the 990-N deadline the day you take office, since that single missed date, repeated three times, is the failure mode that actually costs organizations their exempt status. Our guides on 990-N and Form 990-N walk through the actual filing screen field by field if you've never done it.
How do I actually file the 990-N before the deadline?
File Form 990-N through the IRS's Tax Exempt Organization Search system, which hosts the e-Postcard filing tool directly (the older Urban Institute-hosted portal was retired years ago; everything now runs through irs.gov) [1]. You'll need your organization's EIN, legal name and any "doing business as" name, mailing address, the name and address of a principal officer, your tax year, confirmation that gross receipts are $50,000 or less, and a yes/no on whether the organization has terminated or gone out of business. That's genuinely the whole form. Most treasurers can complete it in under 10 minutes once they have the EIN and officer information handy. There's no login or account creation required for a first-time 990-N filer beyond basic identity verification through the IRS system. If you don't know your organization's EIN or aren't sure who filed last year, check old bank statements, prior board meeting minutes, or the IRS Tax Exempt Organization Search [4], which lists filing history by EIN and will show you the last 990-N submitted, if any.
What if my organization has never filed a 990 at all?
If you're not sure your organization even has 501(c)(3) status, or you inherited a checkbook with no paperwork, start by searching the EIN (or the organization's name) on the IRS Tax Exempt Organization Search tool [4]. That tells you three things at once: whether the EIN is registered as exempt, what filing category it's in, and whether it's already been auto-revoked. Some booster clubs operate for years as informal groups under a school's umbrella, using the school's tax ID or no formal exempt status at all. That's a different problem than a lapsed 990-N and generally needs its own research into whether the group should incorporate and apply for exemption via Form 1023 or 1023-EZ. This is genuinely a place where a quick call to the IRS Exempt Organizations helpline or a local nonprofit legal clinic saves a lot of guesswork. This article and the BoosterLedger $99 Treasurer Kit can help you organize what you find and build a filing calendar going forward, but neither replaces an accountant or attorney's advice on your specific situation. We're not a law firm or a CPA firm, and nothing here guarantees any particular filing or exemption outcome.
What should a new treasurer check first, before worrying about this year's deadline?
Before you touch this year's 990-N, check three things. First, search the EIN on the IRS Tax Exempt Organization Search to confirm current exempt status and see the filing history [4]. Second, ask the outgoing treasurer (or the board) for the last three years of filed 990-Ns or 990-EZs; if nobody can produce them, that's your real emergency, not the upcoming deadline. Third, check your state's charity registration status with your state attorney general's charity office or secretary of state, since many states require separate annual charitable solicitation registration on top of the federal 990 filing, with its own deadline and its own lapse consequences. Once you've confirmed the organization is in good standing (or identified exactly how far behind it is), only then does May 15 (or your organization's specific 5th-month deadline) become the thing to calendar. A $99 one-time State-Personalized Treasurer Kit can give a new treasurer a pre-built calendar and checklist for their specific state, but the free first step, searching the IRS tool, costs nothing and takes five minutes.
Frequently asked questions
What is the exact deadline for filing Form 990-N?
The 15th day of the 5th month after your organization's accounting period ends. For a calendar-year filer (year ending December 31), that's May 15 of the following year. If your fiscal year ends June 30, your 990-N is due November 15. Confirm your organization's specific fiscal year end with your bylaws or prior filings, since it drives the actual due date [1].
Is there a penalty for filing the 990-N late?
No direct monetary penalty applies to a late 990-N, unlike the 990 or 990-EZ. The real risk is cumulative: fail to file for three consecutive years (990-N, 990-EZ, or 990, any combination) and the IRS automatically revokes your tax-exempt status under Internal Revenue Code Section 6033(j), with no separate warning required by statute [2].
Can I get an extension for Form 990-N?
No. There's no extension form for the 990-N because there's nothing to extend; it's an informational notice, not a return with tax due. If your organization instead needs to file the full Form 990 or 990-EZ, those can be extended using Form 8868, but the 990-N itself just needs to be filed whenever you get to it, ideally before the deadline [6].
What does a treasurer do?
A treasurer tracks all organizational income and expenses, reconciles the bank account, reports financial status to the board, and handles required filings like the 990-N. In a small booster club or PTO, this is usually a part-time volunteer role that gets heavier during fundraiser season and at fiscal year-end when annual filings come due.
What is Form 990?
Form 990 is the IRS's annual information return for tax-exempt organizations, disclosing revenue, expenses, program activities, and governance details. Larger nonprofits file the full version; smaller ones can file the shorter 990-EZ or, if gross receipts are normally $50,000 or less, the simplified 990-N e-Postcard instead [1] [5].
What is a 990 tax form used for, in plain terms?
It's how the IRS and the public track what a tax-exempt organization does with its money, without that organization owing corporate income tax on the activity. It's a disclosure document, not a tax bill. Filing it (in whichever version applies to your size) is what keeps your exempt status active.
What does a club treasurer do that's different from other officers?
The club treasurer specifically owns the money: deposits, expense tracking, bank reconciliation, budget reporting, and annual IRS/state filings. Other officers (president, secretary) handle governance and communication. In most small clubs, the treasurer is the only officer who needs to understand tax filing deadlines like the 990-N due date.
How do I check if my organization already lost its tax-exempt status?
Search your organization's name or EIN on the IRS Tax Exempt Organization Search tool at irs.gov. It shows current exempt status, filing history, and lists organizations on the Auto-Revocation List along with the effective revocation date, if applicable [3].
What happens if my booster club's exemption gets auto-revoked?
Your organization is no longer tax-exempt for federal purposes, donor contributions generally stop being tax-deductible, and you may owe corporate income tax on revenue earned while revoked. Small organizations can often apply for retroactive reinstatement under Revenue Procedure 2014-11 if they act within 15 months of the revocation date [4]. Confirm current process and forms with the IRS.
Does every small booster club have to file something with the IRS every year?
Yes. Nearly every 501(c)(3), regardless of size, must file one of three forms annually: Form 990, Form 990-EZ, or Form 990-N, based on gross receipts and total assets. There's no exemption from filing based on being small, only an exemption from filing the longer forms [1] [5].
What information do I need to file Form 990-N?
Your organization's EIN, legal name and any DBA, mailing address, the name of a principal officer, your tax year, confirmation gross receipts are $50,000 or less, and whether the organization has terminated. No financial statements or attachments are required [1].
Where do I actually file Form 990-N online?
Through the IRS's Tax Exempt Organization Search tool at irs.gov, which hosts the e-Postcard filing system directly. There's no fee and no paper option; the whole submission usually takes under 10 minutes once you have your EIN and officer details ready [1].
