TL;DR
Form 990-N (the e-Postcard) is the IRS's free, 8-question online filing for small nonprofits with gross receipts normally $50,000 or less. It's due every year by the 15th day of the 5th month after your fiscal year ends. Miss it three years running and the IRS automatically revokes your tax-exempt status. Filing takes about 10 minutes through the IRS's e-Postcard system.
What is Form 990 and how does 990-N fit in?
Form 990 is the annual information return that tax-exempt organizations file with the IRS to report money in, money out, and basic governance facts. It's not a tax bill in the way a personal 1040 is. Most booster clubs, PTOs, and youth sports groups don't owe income tax on donations and dues, but the IRS still wants an annual look at the books to confirm the organization is behaving like the exempt group it claims to be. There are four versions, sized to the organization's money. Form 990-N (the "e-Postcard") is for organizations with gross receipts normally $50,000 or less. Form 990-EZ is for organizations with gross receipts under $200,000 and total assets under $500,000. Full Form 990 is for anything bigger. Form 990-PF is for private foundations regardless of size. Here's the number that matters most to a small booster club: if your gross receipts are normally $50,000 or less, you're eligible to file the 990-N, and most volunteer-run booster and PTO groups land in exactly this bucket [1]. "Normally" is an IRS term of art, not casual language, covered a few sections down. If you're searching "what is a 990 tax form" or "what is the 990" because you just inherited a shoebox of receipts, the short version is this: it's the annual report that keeps your group's tax-exempt status alive. Skip it three years straight and the IRS turns the status off automatically, no warning letter required beyond what they've already sent.
What exactly is Form 990-N (the e-Postcard)?
| 990-N | Gross receipts normally ≤ $50,000 | 8 basic facts | Online only, IRS system | |
|---|---|---|---|---|
| 990-EZ | Gross receipts < $200,000, assets < $500,000 | Summarized financials, program details | Electronic filing required for most orgs | |
| Form 990 | Gross receipts ≥ $200,000 or assets ≥ $500,000 | Full financials, compensation, governance | Electronic filing required | |
| 990-PF | Private foundations | Full financials, grant activity | Electronic filing required | Source for thresholds: IRS, "Annual Exempt Organization Return: Who Must File" [3]. A lot of small booster clubs qualify for 990-N but choose to file 990-EZ instead anyway, because a grant funder or school district asked for a financial summary. That's a legitimate reason to file the bigger form voluntarily. Nothing stops you from filing 990-EZ even if you'd qualify for the e-Postcard. |
Form 990-N is an 8-question online form. No paper option exists. You file it through the IRS's electronic system, and there's no fee to file it [2]. The eight data points the IRS wants are: your organization's legal name and any doing-business-as name, EIN, mailing address, website (if you have one), confirmation that gross receipts are $50,000 or less, confirmation the organization is still in business, the name and address of a principal officer, and your tax year [2]. That's it. No revenue detail, no expense breakdown, no balance sheet. If your board hasn't nailed down a bookkeeping system yet, 990-N is forgiving in a way that full Form 990 is not. Compare that to the workload on the bigger forms: | Form | Who files it | What it asks for | Filing method |
Who has to file 990-N, and what does "gross receipts normally $50,000 or less" mean?
You can file 990-N if your organization's gross receipts are "normally $50,000 or less." The IRS defines "normally" using a rolling average, not a single year's number, which trips people up constantly. For an organization in its first tax year, it qualifies if it received $75,000 or less. In its first two years, it qualifies if the total for both years is $150,000 or less. After three or more years in existence, the average of the current year plus the prior two years has to be $50,000 or less [4]. So a booster club that had a huge one-time fundraiser (a $60,000 stadium renovation drive, say) doesn't automatically get bumped out of e-Postcard eligibility. The IRS looks at the three-year average, not the peak year. A few groups are carved out entirely and can't use 990-N even if small: organizations included in a group return, private foundations (they file 990-PF regardless of size), and section 509(a)(3) supporting organizations [1]. If your booster club is a PTA unit under a state PTA's group exemption, check with your state PTA office before filing anything on your own, since a group return may already cover you. One more wrinkle worth flagging: churches, their integrated auxiliaries, and conventions of churches are generally exempt from filing any 990 series form at all, small or large [5]. That doesn't usually apply to a school booster club, but if your group is affiliated with a religious organization, it's worth confirming with the IRS which category you actually fall into.
When is the 990-N deadline?
Form 990-N is due every year by the 15th day of the 5th month after the end of your organization's fiscal year [6]. For a group running on a calendar year (January 1 to December 31), that's May 15. For a group on a school-year fiscal calendar (July 1 to June 30), that's November 15. Unlike a lot of IRS deadlines, there's no extension form for 990-N. You can't file Form 8868 to push the date back for the e-Postcard the way you can for the larger 990 series returns. If you miss the date, you just file late, and the IRS's own guidance says there's no penalty for a late 990-N as long as you eventually file it [7]. The real danger isn't a late fee. It's what happens after three consecutive misses, covered next. Mark your fiscal year-end on the calendar the day you take over as treasurer, then count forward. New treasurers inherit half-finished books and no idea what the prior treasurer filed or when. Figuring out your fiscal year and counting five months forward is the single most useful ten minutes you'll spend in your first week on the job.
What happens if you miss the 990-N deadline?
Nothing happens after one missed year, and nothing happens after two. The IRS doesn't fine small organizations for a late e-Postcard [7]. But miss three years in a row and the law is automatic: the organization's tax-exempt status is revoked by operation of law, effective on the filing due date of the third year. This rule comes straight from the Pension Protection Act of 2006, codified at Internal Revenue Code section 6033(j). The statute states that an organization that fails to file required annual returns or notices for three consecutive years "shall have its status as an organization exempt from tax... revoked" as of the filing due date for the third year . There's no discretion in it. The IRS doesn't send a warning that says "this is your final notice." It's a mechanical trigger written into the tax code, and it has caught a huge number of volunteer-run groups off guard since it took effect for tax years beginning in 2007. Over 760,000 organizations lost their exempt status this way in the first big revocation wave in 2011, and the IRS still auto-revokes tens of thousands of small organizations every year, mostly for exactly this reason: a treasurer left, nobody knew the group had to file anything, and three years slipped by silently . If your booster club has changed treasurers two or three times without a clean handoff, assume you might be on that list until you've checked.
How do you check if your organization has already been auto-revoked?
Use the IRS Tax Exempt Organization Search tool at irs.gov and look up your organization by name or EIN . The tool shows current exempt status, and it also has a specific "Auto-Revocation List" you can search separately to see if and when a revocation happened. If you find your group on that list, don't panic, but don't ignore it either. Losing exempt status means the organization is treated as a taxable entity going forward, donations made after the revocation date generally aren't tax-deductible to donors, and depending on your state, your charity registration or raffle license may hinge on active federal exempt status. Reinstatement is possible but it takes real paperwork: filing Form 1023 (or 1023-EZ if you qualify) with a reinstatement request, and in many cases paying the standard user fee again . Retroactive reinstatement to the original revocation date is available for organizations that show reasonable cause for the filing failures, but the IRS decides that on a case-by-case basis, so confirm your specific situation and any current fee amounts directly with the IRS. This is exactly why a clean [990](/articles/treasurer-basics/990) filing habit, year after year, matters more than almost anything else on a volunteer treasurer's checklist. It's boring paperwork until the year it isn't.
How do you actually file Form 990-N, step by step?
File Form 990-N through the IRS's online e-Postcard system. As of the current system, you access it through an IRS.gov-linked portal and sign in with an IRS-approved login (the IRS moved e-Postcard filing to its Login.gov/ID.me-based system in recent years, so check the current sign-in method on the IRS's Form 990-N filing page) [2]. Before you sit down to file, gather these five things: your organization's EIN, your legal name and any DBA name exactly as registered, your mailing address, your tax year dates, and the name and address of one principal officer (this is often the treasurer or board president, whoever the organization has designated). You'll also confirm your gross receipts are $50,000 or less and that the organization is still operating. The whole process usually takes under 15 minutes if you have those five things ready. There's no login fee, no filing fee, and you get an immediate confirmation once it's accepted. Keep a screenshot or saved PDF of that confirmation in your treasurer binder or shared drive. It's the single easiest piece of evidence to lose track of during a treasurer handoff, and the first thing an incoming treasurer should ask to see.
What if you can't remember your organization's EIN or exempt status?
This happens constantly with volunteer-run booster clubs and PTOs, especially after two or three officer transitions with no formal handoff. Start with the IRS Tax Exempt Organization Search tool, searching by organization name and state . If that doesn't turn it up, check old bank statements or grant applications, since the EIN usually appears on both. If you genuinely can't find any record that the organization ever applied for tax-exempt status, that's a different and bigger problem than a missed 990-N, and it usually means starting the exemption application process from scratch with Form 1023 or 1023-EZ. Don't assume that because your group has always "acted like" a nonprofit, it's actually recognized as one by the IRS. Plenty of small booster clubs operate for years collecting donations under an old parent organization's EIN, or under no formal exemption at all, without anyone realizing it until an audit or a school district finance office asks for documentation. A well-organized 990-N filing history, EIN letter, and exemption determination letter, kept together in one place, is worth more to your successor than a fancy accounting system. This is the exact gap a $99 one-time State-Personalized Treasurer Kit is built to close: it bundles the EIN lookup steps, filing deadline tracker, and document checklist a first-time treasurer needs, personalized to your state's specific rules. Check it out at /treasurer-kit-builder if you're starting from a blank folder.
What does a treasurer actually do, and where does 990-N fit into the job?
A treasurer's core job is keeping the organization's money honest and its paperwork current. That breaks into a few concrete buckets: tracking income and expenses, reconciling the bank account monthly, presenting financial reports to the board, safeguarding cash from fundraisers and events, and filing whatever the IRS and the state require to keep the organization's legal status intact. What does a treasurer do in a club, specifically? In a booster club, PTO, or youth sports organization, that usually means: recording every deposit and expense (concession stand cash, spirit-wear sales, sponsorship checks), keeping receipts and invoices, preparing a monthly or quarterly report for the board, managing the checking account and any debit cards, and handling the annual federal filing, whether that's 990-N, 990-EZ, or full Form 990. Many treasurers also handle state-level charity registration renewals and raffle license paperwork, since those often run on a similar annual clock. What does a club treasurer do that a regular member doesn't? The legal and financial exposure is different. A treasurer who signs a 990-N is attesting the organization's numbers and status are accurate. A treasurer who lets three years of filings lapse is the reason the whole board loses tax-exempt status, sometimes without knowing it happened. That's not a scare tactic, it's just how IRC 6033(j) works . The job is mostly quiet, routine bookkeeping, but the two or three deadlines a year (990-N, state charity renewal, raffle license renewal) are the parts that actually carry legal weight.
990-N vs 990-EZ vs full Form 990: which one does your group file?
| Gross receipts normally $50,000 or less | 990-N (or 990-EZ/990 voluntarily) | |
|---|---|---|
| Gross receipts less than $200,000 and total assets less than $500,000 | 990-EZ or full 990 | |
| Gross receipts $200,000 or more, or total assets $500,000 or more | Form 990 | |
| Private foundation, any size | Form 990-PF | Source: IRS, "Annual Exempt Organization Return: Who Must File" [3]. A note on strategy, more than eligibility: if your booster club is close to that $50,000 line, or if you had one unusually large fundraising year, it's often worth filing 990-EZ anyway rather than trying to prove you still qualify for 990-N under the three-year averaging rule. The EZ form takes longer to prepare but it gives you a clean financial record that's genuinely useful when a new treasurer takes over, or when a school district or bank asks for documentation of your finances. The 990-N gives the IRS almost nothing to look at later, which is convenient in the moment and unhelpful during a handoff five years later. |
The form you file depends on gross receipts and total assets, measured the way the IRS specifies, more than your gut sense of "we're a small group." | Situation | Form to file |
Does your state require anything besides the federal 990-N?
Yes, in most states, and this is the part treasurers most often miss. Federal tax-exempt status and state charity registration are two separate systems that don't automatically talk to each other. Many states require nonprofits that solicit donations to register annually with the state attorney general's office or a state charities bureau, sometimes with their own financial reporting requirements layered on top of, or independent from, the federal 990 series. The rules vary enough state to state that there's no single number to quote here. Some states tie their reporting thresholds to your federal 990 form type, some have flat annual registration fees regardless of size, and some exempt small all-volunteer groups from registration entirely. Confirm the current rule with your state's charity registration office or attorney general's charities division before assuming your federal 990-N filing is the whole job. If your group also runs raffles, most states layer a separate raffle or gaming license on top of general charity registration, often with its own annual renewal and reporting. Don't assume one filing covers the other. Confirm both requirements directly with your state's charity office and gaming/raffle licensing authority.
Frequently asked questions
What is Form 990?
Form 990 is the annual information return tax-exempt organizations file with the IRS reporting income, expenses, and governance details. It comes in four sizes based on gross receipts and assets: 990-N for the smallest organizations, 990-EZ and full Form 990 for mid-size and larger ones, and 990-PF for private foundations, per IRS guidance on who must file [3].
What is a 990 tax form and who has to file it?
It's the yearly report the IRS requires from most tax-exempt organizations to keep their exempt status active. Nearly every 501(c)(3) or 501(c)(4) group has to file some version, even if gross receipts are zero, unless it falls under a specific exception like churches or is covered by a group return [1][5].
What is Form 990-N and who can use it?
Form 990-N, the e-Postcard, is an 8-question online-only filing for organizations with gross receipts normally $50,000 or less. It's free to file, asks for basic identifying facts (EIN, address, principal officer, tax year), and takes about 10 minutes through the IRS's online system [2][4].
What does a treasurer do?
A treasurer tracks all money in and out, reconciles bank accounts, reports finances to the board, safeguards cash from fundraisers, and files required federal and state paperwork, including the annual 990-N or 990-EZ and any state charity or raffle license renewals.
What does a club treasurer do differently from other officers?
The treasurer carries legal responsibility for the organization's financial records and required filings. Missing three straight years of 990-N filings triggers automatic IRS revocation of tax-exempt status under IRC 6033(j), a risk that specifically sits on the treasurer's desk more than any other board role [8].
When is Form 990-N due?
990-N is due every year by the 15th day of the 5th month after your organization's fiscal year ends. Calendar-year organizations (Jan 1 to Dec 31) file by May 15. There's no extension form available for 990-N specifically [6].
What happens if I file 990-N late?
There's no monetary penalty for filing 990-N late, according to IRS guidance. The real risk is cumulative: three consecutive missed years triggers automatic revocation of tax-exempt status by law, with no additional warning required beyond what the IRS already sends [7][8].
How do I know if my organization's tax-exempt status was already revoked?
Search the IRS Tax Exempt Organization Search tool at irs.gov by your organization's name or EIN. It shows current status and includes a searchable auto-revocation list showing the date status was revoked, if applicable [10].
Can a booster club file 990-N if it had one unusually big fundraising year?
Possibly yes. Eligibility is based on a rolling average, not one year's total: after three-plus years of existence, the average of the current year plus the prior two years has to be $50,000 or less. One big year doesn't automatically disqualify you [4].
What information do I need to file Form 990-N?
You need the organization's legal name and any DBA name, EIN, mailing address, website if applicable, confirmation gross receipts are $50,000 or less, confirmation the organization is still operating, the name and address of a principal officer, and your tax year dates [2].
Does filing 990-N cost anything?
No. Form 990-N has no filing fee and requires no paid preparer, since it's just eight questions submitted through the IRS's free online e-Postcard system. Any group that pays a third party a large fee just to submit 990-N is likely overpaying for a task that takes about 10 minutes.
Do state charity registration rules replace the need to file 990-N?
No, they're separate systems. Federal 990-N filing with the IRS does not satisfy state charity registration or raffle licensing requirements, and vice versa. Confirm your state's specific rules directly with your state attorney general's charities office or state charity registration office.
What is a treasurer of a club responsible for besides taxes?
Beyond IRS and state filings, a club treasurer manages the checking account, reconciles it monthly, tracks cash from events like concession stands or raffles, prepares financial reports for board meetings, and keeps records organized enough to hand off cleanly to the next treasurer.
