990-N forms explained: who files it and how e-postcard works

Last updated 2026-07-24

What is Form 990-N?

Form 990-N, officially called the e-Postcard, is the simplest of the IRS's annual information returns for tax-exempt organizations. It's not a paper form at all. You file it entirely online through the IRS's filing system, and it asks eight basic questions: your organization's legal name, EIN, tax year, mailing address, website (if you have one), confirmation that gross receipts are normally $50,000 or less, and a statement that the organization hasn't terminated. ^[1] There's no financial detail required, no balance sheet, no list of officers' compensation. That's the whole point. Congress created this option in the Pension Protection Act of 2006 specifically so tiny nonprofits, the kind run by volunteers out of a kitchen drawer full of receipts, wouldn't have to produce a full accounting just to stay in good standing. ^[2] If your booster club, PTO, or youth sports league brings in more than $50,000 in a typical year, you don't qualify for the 990-N. You'd file Form 990-EZ or the full Form 990 instead, depending on your size. This article assumes you're in e-Postcard territory, which covers the overwhelming majority of small booster and parent groups.

What is Form 990 (the full version), and how is it different from the 990-N?

990-N (e-Postcard)	Gross receipts normally ≤ $50,000	8 basic questions, no financials
990-EZ	Gross receipts < $200,000, assets < $500,000	Financial summary, program info
Full 990	Gross receipts ≥ $200,000, or assets ≥ $500,000	Full financials, governance detail	See our companion pieces on the 990 tax form and IRS Form 990 for more on the bigger versions.

Form 990 is the umbrella name for the IRS's annual information return for tax-exempt organizations, and it comes in three tiers depending on how much money moves through your group. The full Form 990 is a multi-page return with financial statements, program descriptions, and governance questions, required for organizations with gross receipts of $200,000 or more, or total assets of $500,000 or more. ^[3] Form 990-EZ is the middle tier, for organizations with gross receipts under $200,000 and total assets under $500,000. It's still a real tax form with actual numbers on it, just shorter than the full 990. Form 990-N is the bottom tier: the e-Postcard, for organizations with gross receipts normally $50,000 or less. Some groups also choose to file the 990-EZ voluntarily even when they qualify for the N, because a bank or grant funder wants to see actual financial figures on record with the IRS. That's a legitimate reason to file up a tier, but it's optional. | Form | Who files it | What it requires |

Who has to file the 990-N?

Any organization recognized as tax-exempt under section 501(c) of the Internal Revenue Code, whose gross receipts are normally $50,000 or less, generally must file some version of the 990 series annually. If you're under that threshold and don't want to do the paperwork of the EZ or full form, the 990-N is the one built for you. ^[1] "Normally $50,000 or less" is an IRS term of art, not a literal single-year test. The agency actually looks at an average over the last three years (or fewer, if you're newer). A booster club that had a huge one-time car wash fundraiser bump to $58,000 one year can still qualify if the three-year average stays at or under $50,000. ^[4] If you're right at the edge, it's worth confirming with the IRS or a tax preparer familiar with small nonprofits before you assume which form applies. Churches and certain church-affiliated organizations are generally exempt from the annual filing requirement altogether, along with a short list of other statutorily excepted organizations. ^[1] Most booster clubs, PTOs, and youth sports leagues don't fall into that carve-out, so don't assume you're off the hook just because you're small and volunteer-run. One thing that trips people up: you have to already have your 501(c)(3) or other tax-exempt determination (or at least have applied and gotten an EIN as a nonprofit) before the 990-N filing requirement kicks in. A brand-new booster club that hasn't yet applied for exemption is in a different situation entirely, and should sort out its exemption status before worrying about annual filings.

How do you actually file the 990-N?

You file Form 990-N through the IRS's online e-Postcard filing system, not by mail and not on paper. You'll need your organization's EIN, the legal name and address on file with the IRS, your tax year end date, and confirmation of the gross receipts threshold. ^[1] The whole process takes most treasurers under ten minutes once they have the EIN and prior-year filing info in hand. There's no fee to file. If you've filed before, the system will often have your organization's basic info pre-loaded, which speeds things up. A few practical tips from treasurers who've done this more than once: keep a copy of your confirmation email or screenshot every year, because the IRS doesn't always make historical 990-N filings easy to pull up later, and a bank or new board member may ask you to prove you filed. Also double check that the mailing address and responsible party on file with the IRS match your current officers; boards turn over every year or two in most booster and PTO groups, and an outdated address means you might miss an IRS notice entirely. If your organization has never filed before or you're not sure whether a prior treasurer filed, the safest move is to search the IRS's Tax Exempt Organization Search tool, which lists 990-N filings going back several years. ^[5]

When is the 990-N due?

Form 990-N is due by the 15th day of the 5th month after the end of your organization's fiscal year. ^[1] For an organization on a calendar-year fiscal year (ending December 31), that means the filing is due May 15 of the following year. Many booster clubs and PTOs run on a school-year fiscal calendar instead, often July 1 to June 30, which pushes the due date to November 15. Check your own organization's bylaws or your IRS determination letter to confirm your actual fiscal year; it's not automatically the calendar year just because that's more common. Unlike income tax returns, there's no extension form for the 990-N specifically, and importantly, there's no monetary penalty for filing it late in a single year. ^[1] But don't let that make you casual about it. The real risk isn't a fine, it's what happens if you miss it for three years running, which we cover next.

What happens if you miss the 990-N deadline, or skip it for multiple years?

A single late 990-N doesn't trigger a monetary penalty the way a late tax return would for a regular business. But the IRS's rule is unforgiving on a longer timeline: if you fail to file any required return (990, 990-EZ, or 990-N) for three consecutive years, your organization's tax-exempt status is automatically revoked, by operation of law, on the filing due date of the third year. ^[6] This isn't a warning letter followed by a grace period. It's automatic. The Pension Protection Act of 2006 wrote this into the tax code directly. The IRS's own guidance states: "an organization's tax-exempt status is automatically revoked if it does not file required Form 990-series returns or notices for three consecutive years." ^[6] The IRS then publishes your organization's name on its Auto-Revocation List, and your donors lose the ability to deduct contributions to your group, retroactive to the revocation date. This catches an enormous number of small volunteer-run nonprofits, precisely because they're small, volunteer-run, and turn over leadership every year or two with no formal handoff process. A treasurer graduates their kid out of the program, the next parent doesn't know a filing was ever required, and three years later the group's exemption is gone without anyone realizing it. If this has already happened to your organization, don't panic, but do act. The IRS has a formal process (Revenue Procedure 2014-11) for streamlined reinstatement for small organizations that qualified for 990-N or 990-EZ in the years they missed, which is faster and cheaper than a full reapplication. We cover the reinstatement process in detail elsewhere; for now, know that it exists and that acting sooner rather than later matters, because state-level consequences (like losing sales tax exemption or charitable registration) can pile on top of the federal one.

What is a treasurer, and what does a treasurer do?

A treasurer is the officer of a club, PTO, or booster organization responsible for tracking money in and out, keeping the organization's financial records straight, and making sure required filings (like the 990-N) get done on time. In a volunteer nonprofit, the treasurer is usually the only person who touches the books regularly, which makes the role more important than the title might suggest. Day to day, what a treasurer does varies by organization size, but the core duties are pretty consistent across booster clubs, PTOs, and youth sports leagues: collecting and depositing cash from fundraisers and dues, paying vendors and reimbursing volunteers, reconciling the bank statement every month, keeping receipts and records organized enough that someone else could understand them, and filing the annual 990-N or other required return. In a smaller club, the treasurer often also handles things a larger nonprofit would split across a bookkeeper, a controller, and a compliance officer: raffle license applications, sales tax questions on concession stand sales, W-9 collection from paid coaches or referees, and reporting to the board at every meeting. It's a real job, even though almost nobody gets paid to do it.

What does a club treasurer do differently from a corporate treasurer?

A club treasurer (whether for a booster club, PTO, or youth sports league) does a version of the same job a corporate treasurer does, just at a much smaller scale and usually without any professional training. The fundamentals overlap: manage cash, track income and expenses, keep records, report to leadership, meet filing deadlines. What's different is context. A club treasurer is almost always a volunteer parent doing this on top of a full-time job, usually with no accounting background, often inheriting a shoebox or a half-finished spreadsheet from whoever did it last. There's rarely a finance department to lean on, and the amounts of money involved, often thousands rather than millions, don't make it less risky; cash-heavy fundraisers like concession stands and raffles are actually a common source of both honest errors and, occasionally, real fraud in these small organizations. The stakes are also different in kind. A corporate treasurer worries about interest rate risk and covenant compliance. A club treasurer worries about whether the 990-N got filed before the exemption lapses, whether the raffle license is current, and whether last year's cash box actually reconciles to what got deposited. It's a smaller job in dollar terms and a bigger job in relative responsibility, since one missed filing can cost the whole organization its tax-exempt status.

What does a treasurer of a club actually need to track for the 990-N specifically?

Even though the 990-N itself doesn't ask for financial detail, a club treasurer still needs internal records solid enough to know, with confidence, whether the organization's gross receipts are normally $50,000 or less. Gross receipts means total money received from all sources during the year before subtracting any costs or expenses, not net profit. ^[4] That means a booster club that brings in $60,000 in fundraiser revenue but only nets $15,000 after paying for supplies and venue costs is still over the $50,000 gross receipts line for 990-N purposes, at least for that year. A treasurer needs a running total, ideally updated monthly, of all deposits: dues, concession sales, raffle ticket sales, sponsorship checks, everything, before expenses come out. Practically, the records worth keeping year-round are: a bank reconciliation done monthly, a simple income and expense ledger (even a spreadsheet is fine at this scale), copies of the prior three years' 990-N confirmations, your EIN and IRS determination letter, and your organization's fiscal year end date written down somewhere a new treasurer will actually find it. That last part sounds trivial and causes more missed filings than anything else.

What if your organization doesn't have an EIN or has never filed anything?

If your booster club, PTO, or youth league has been operating on a member's personal bank account or has genuinely never filed with the IRS, you're in a different situation than a routine missed 990-N, and it's worth sorting out before you file anything. You'll need to get an EIN for the organization itself (free, directly from the IRS, not a paid third-party service), determine whether the organization has ever applied for or received tax-exempt recognition, and figure out your actual fiscal year. Some small local groups (particularly those under a national umbrella organization, like some PTAs) may already be covered under a group exemption held by the parent organization, meaning individual chapters don't need to file separately for exemption, though annual return requirements can still apply at the chapter level. Confirm with the IRS and your state charity office to be sure about your specific situation, since group exemption rules and state registration requirements vary and this isn't something worth guessing on. Starting from zero is more paperwork upfront than filing an annual e-Postcard, but it's far less painful than discovering years later that donations were never properly deductible or that state charitable registration was never filed either.

Do you still need a treasurer kit or outside help for something this simple?

For a lot of small booster clubs and PTOs, the 990-N itself really is a ten-minute task once you know your EIN, fiscal year, and gross receipts range. You don't need an accountant for the filing itself. Where volunteer treasurers usually get into trouble isn't the 990-N form; it's everything around it: not knowing the fiscal year end, not knowing whether the prior treasurer filed, not having the EIN written down anywhere, or not realizing the three-year revocation clock even exists until year four. That's less a tax problem and more a records-handoff problem, and it repeats every time leadership turns over. If your organization wants a state-specific reference that lays out your filing calendar, gross receipts test, and what to hand the next treasurer, BoosterLedger's $99 one-time State-Personalized Treasurer Kit builds that out for your specific state and organization type, so the answer to "did we file this year" doesn't depend on one volunteer's memory. It's a reference tool, not tax advice, and it doesn't replace confirming specifics with the IRS or your state charity office. Whether you use a kit or build your own binder, the goal is the same: make the filing requirement survive the person currently holding the job.

What's the difference between 990-N, 990-EZ, and the full 990 in plain terms?

Think of the three forms as a ladder based on money, not complexity of mission. A tiny booster club raising $12,000 a year for uniforms and a big regional youth sports association moving $400,000 a year are both tax-exempt and both file a version of Form 990, but they're on completely different rungs. 990-N is for the smallest groups, gross receipts normally $50,000 or less, and it's just eight questions online with no financial disclosure. ^[1] 990-EZ steps up to actual financial reporting, for groups under $200,000 in gross receipts and under $500,000 in assets. The full Form 990 is for anything bigger, gross receipts of $200,000 or more or total assets of $500,000 or more, and includes governance questions, compensation disclosure, and detailed program service reporting. ^[3] A quick gut check: if your organization's total money in for the year, before any expenses, honestly rounds to "tens of thousands," you're probably a 990-N filer. If it rounds to "low hundreds of thousands," you've likely crossed into 990-EZ territory and should recheck the thresholds directly on IRS.gov rather than guess.

Frequently asked questions

What is a 990 tax form?

A 990 tax form is the annual information return that tax-exempt organizations file with the IRS to report on their activities and, depending on size, their finances. It comes in three versions: the full Form 990, the shorter Form 990-EZ, and the 990-N e-Postcard for organizations with gross receipts normally $50,000 or less. It's not an income tax return; exempt organizations generally don't owe tax on qualifying income.

What is Form 990 used for?

Form 990 gives the IRS and the public a picture of a tax-exempt organization's mission, activities, and finances each year. It confirms the organization is still operating within its exempt purpose and hasn't exceeded income or asset thresholds that would require a more detailed version of the form. Most of this information also becomes publicly searchable through the IRS's Tax Exempt Organization Search tool.

What is the 990-N (e-Postcard)?

The 990-N is the simplest annual filing for small tax-exempt organizations, available to those with gross receipts normally $50,000 or less. It's filed entirely online, asks eight basic questions, requires no financial detail, and has no filing fee. It's due by the 15th day of the 5th month after the organization's fiscal year ends.

What does a treasurer do in a club?

A club treasurer tracks all money coming in and going out, reconciles the bank account regularly, keeps organized financial records, handles reimbursements and vendor payments, and makes sure required filings like the 990-N happen on time. In many booster clubs and PTOs, the treasurer is also the person who applies for raffle licenses and handles state charity registration.

What does a treasurer of a club do at meetings?

At board meetings, a club treasurer typically presents a current financial report: cash on hand, recent income and expenses, upcoming bills, and progress toward fundraising goals. They answer questions from other officers or members about spending, flag any budget concerns, and keep meeting minutes or reports on file to document the organization's financial decisions over time.

Who is required to file Form 990-N?

Most tax-exempt organizations under section 501(c) with gross receipts normally $50,000 or less must file Form 990-N annually, unless they're churches or a small list of other excepted organizations. If gross receipts exceed that threshold, the organization must file Form 990-EZ or the full Form 990 instead, depending on size.

What happens if a nonprofit doesn't file Form 990-N?

Missing a single year doesn't carry a monetary penalty, but missing three consecutive years triggers automatic revocation of tax-exempt status under federal law, effective as of the third year's filing deadline. The IRS lists revoked organizations publicly, and donors lose the ability to deduct contributions retroactive to the revocation date.

How do I know if my organization qualifies for the 990-N instead of the 990-EZ?

Check whether your gross receipts, averaged over the current year and the two prior years, are normally $50,000 or less. If yes, you can file the 990-N. If your gross receipts are higher but under $200,000 (with assets under $500,000), you'd file the 990-EZ instead. Confirm your specific numbers against current IRS thresholds if you're near the line.

Is there a fee to file Form 990-N?

No. Form 990-N is free to file through the IRS's online system. If a website or service charges you a fee to submit a basic 990-N on your behalf, understand you're paying for convenience or a bundled service, not something the IRS itself requires you to pay for.

When is the 990-N due each year?

The 990-N is due by the 15th day of the 5th month after your organization's fiscal year ends. For a calendar-year organization (year ending December 31), that's May 15. For a July-to-June fiscal year, common among school-affiliated groups, that's November 15.

Can a new treasurer file a late 990-N for prior years?

You cannot retroactively file separate 990-N e-Postcards for multiple prior missed years the way you might amend a tax return; the 990-N only reflects current status going forward. If your organization already lost its exemption from three consecutive missed years, you'd instead need to go through the IRS reinstatement process rather than backfiling the e-Postcard itself.

Does filing the 990-N replace state charity registration?

No. Form 990-N only satisfies a federal IRS requirement. Most states have a separate charitable solicitation registration requirement, often through the attorney general's office or secretary of state, with its own deadlines and thresholds. Confirm with your state charity office directly, since requirements and dollar thresholds vary significantly by state.
