TL;DR
Form 990-N (the e-Postcard) is the free annual IRS filing for tax-exempt organizations whose gross receipts normally run $50,000 or less. It's due by the 15th day of the 5th month after your fiscal year ends, takes about 10 minutes online through the IRS's filing system, and skipping it three years running gets your booster club's or PTO's exemption automatically revoked.
What is Form 990-N?
Form 990-N is the shortest tax filing the IRS offers, and it's the one most small booster clubs, PTOs, and youth sports groups actually need. The IRS calls it the "e-Postcard" because that's basically what it is: eight data fields, filed online, no financial statements attached. According to the IRS, "Most small tax-exempt organizations whose gross receipts are normally $50,000 or less" can file the 990-N instead of the longer Form 990 or 990-EZ [1]. You're not reporting income and expense line items here. You're confirming your organization still exists, still has the same mission, and is still under the gross receipts threshold. It costs nothing to file. There's no paper version. You do it through the IRS's electronic filing system at IRS.gov, and once it goes through you get an on-screen confirmation, which you should screenshot or save as a PDF immediately, because the IRS doesn't mail you anything afterward. If your organization is new and hasn't figured out which tax form applies yet, start with the general overview of Form 990 and the plain breakdown of the 990 tax form family before assuming 990-N is right for you.
Who has to file Form 990-N?
You file the 990-N if your organization is tax-exempt (or claims exemption without ever having applied) and your gross receipts are normally $50,000 or less per year. "Normally" matters here: the IRS looks at averages over a rolling period, more than the most recent year. For an organization in its first year, gross receipts of $75,000 or less count as normal. For an organization that's been around two years, the average of the current and prior year has to be $60,000 or less. For anyone three years or older, the IRS averages the current year plus the two immediately preceding it, and that average has to be $50,000 or less [1]. This tripping point catches a lot of booster clubs that have one big fundraising year (a car wash blowout, a huge raffle, a big banquet) and then assume they're stuck filing the full 990 or 990-EZ forever. Not necessarily. Check the three-year average. Most PTOs, youth sports boosters, small robotics clubs, and similar all-volunteer groups land comfortably under $50,000 in gross receipts. If yours does not, you'll file Form 990-EZ or the full Form 990 instead, both of which require actual financial statements, more than a postcard. Churches and certain church-affiliated organizations don't have to file at all, and some governmental units are also exempt from the filing requirement, but ordinary booster clubs and parent groups don't get that exception [2].
When is Form 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. If your fiscal year runs on the calendar year (January through December), that puts your deadline at May 15 of the following year [3]. If your booster club or PTO runs on a school-year fiscal calendar, say July 1 through June 30, your 990-N is due by November 15. Get your actual fiscal year end from your bylaws or your original IRS determination letter, not from habit, because a lot of newly-formed groups default to a calendar year without meaning to. There is no extension form for the 990-N. Unlike the full Form 990, where an organization can file Form 8868 for an automatic six-month extension, the e-Postcard doesn't have an extension mechanism because there's nothing complicated to extend [4]. If you miss the deadline, you just file it late as soon as you can. The IRS doesn't charge a late-filing penalty for the 990-N itself, but missing it repeatedly has a much bigger consequence, which is the next section.
What happens if you miss the deadline or don't file at all?
Miss one year, nothing happens immediately. Miss three years in a row and your organization's tax-exempt status is automatically revoked by law, no warning letter required first. This comes straight from the Pension Protection Act of 2006, which added the requirement that small organizations file some version of the 990 annually, and specified that failure to file for three consecutive years results in automatic revocation of exemption. As the IRS puts it, "Organizations that fail to file required Form 990-series returns for three consecutive years automatically lose their tax-exempt status" [5]. The IRS publishes the list of auto-revoked organizations and updates it monthly. If your group's exemption gets revoked, you'll typically find out not from a letter, but when a bank, a school district, a raffle license office, or a grantor asks for proof of exemption and you can't produce a current one. The practical damage: your organization loses its federal income tax exemption, any donations made to it stop being tax-deductible to the donor, and you may owe corporate income tax on money you took in. Getting reinstated means filing Form 1024 (or 1024-A) for exemption again, sometimes paying a new user fee, and in some cases filing back-year 990s you skipped. It's a real headache, and it's completely avoidable with a five-minute filing once a year. If you're already staring down a revocation notice or you found your group on the auto-revocation list, the process to fix it is a separate topic worth reading in full: see [990](/articles/treasurer-basics/990) and irs form 990 for the reinstatement paths, including streamlined retroactive reinstatement for organizations that file within 15 months of the revocation date [6].
How do you actually file Form 990-N?
You file entirely online through the IRS's Form 990-N Electronic Filing System, and the whole process asks for eight things: the organization's legal name and any "doing business as" name, its mailing address, its Employer Identification Number (EIN), the name and address of a principal officer, the tax year, confirmation the organization's gross receipts are normally $50,000 or less, and a statement if the organization has terminated [1]. A few practical notes that trip people up. You need an EIN before you can file, not a Social Security number, so if your booster club has been running on someone's personal SSN for years, fix that first (you apply for an EIN free directly from the IRS) [7]. You also need to know your organization's exact legal name as the IRS has it on file, which is sometimes different from the name on your bank account or your Facebook page, especially after a rename or a merger with another booster group. Once submitted, the system tells you immediately whether it was accepted or rejected. Save that confirmation. There is no separate mailed confirmation, and if you ever need to prove you filed, that screenshot or downloaded confirmation is your only record.
What is Form 990 (the longer version), and how is it different from 990-N?
| 990-N (e-Postcard) | Gross receipts normally ≤ $50,000 | 8 basic data fields, no financials | Free | |
|---|---|---|---|---|
| 990-EZ | Gross receipts < $200,000 and assets < $500,000 | Summary financial statements, program info | Free to file, may need paid prep help | |
| 990 (full) | Gross receipts ≥ $200,000 or assets ≥ $500,000 | Full financials, schedules, compensation disclosures | Free to file, usually needs paid prep help | A lot of small booster clubs assume they need the full form because it's called "the 990" colloquially, when they actually just need the N. If your treasurer's binder from the last handoff says "Form 990" without specifying which version, check your actual gross receipts average before assuming you're stuck with the long form. |
Form 990 is the IRS's annual information return for larger tax-exempt organizations, a real financial disclosure document with a balance sheet, revenue and expense statement, and program descriptions, not a postcard. Organizations with gross receipts under $200,000 and total assets under $500,000 can usually file the shorter Form 990-EZ instead of the full 990. Organizations above those thresholds file the full Form 990, which runs many pages and often needs an accountant or experienced treasurer to prepare correctly [4]. Here's the quick comparison: | Form | Who files it | What it requires | Cost to file |
What is a 990 tax form, in plain English?
A 990 tax form is the annual report tax-exempt organizations file with the IRS instead of a regular income tax return. It's public information, not a private tax filing, which surprises a lot of first-time treasurers. Unlike an individual or corporate tax return, which the IRS keeps confidential, Form 990 series filings are public records. Anyone can look up your organization's 990 or 990-EZ on sites like the IRS Tax Exempt Organization Search or on nonprofit databases, and see your revenue, major expenses, and officer names [8]. The 990-N is the exception: because it's just eight fields with no financial detail, there's very little to see, but the IRS still lists whether and when you filed it. The purpose of the whole 990 series is accountability. Tax-exempt status is a benefit granted because the organization serves a public or charitable purpose, and the 990 forms are how the IRS (and the public) checks that the organization is still doing what it said it would do, still under whatever size threshold applies, and still operating.
What is a treasurer, and what does a treasurer do?
A treasurer is the officer responsible for an organization's money: tracking what comes in, what goes out, keeping records straight, and making sure required filings like Form 990-N get done on time. In a booster club or PTO, the treasurer is usually the only person who touches the bank account regularly, which is exactly why the role carries so much responsibility for so little institutional support. What does a treasurer do day to day? Deposits checks and cash from fundraisers, pays vendors and reimburses volunteers, reconciles the bank statement every month, keeps receipts and records organized for the next treasurer, and files the group's annual tax paperwork, which for most small groups is exactly the Form 990-N covered above. What does a club treasurer do that's different from a corporate treasurer? Not much, actually, just at a much smaller scale and usually with zero paid staff support. A club treasurer of a youth sports booster group or school PTO handles the same core jobs: cash controls, bank reconciliation, budget tracking, and compliance filings, but does it as a volunteer, often with no accounting background, often inheriting a shoebox of records from whoever held the job last year. What does a treasurer of a club do that a president or secretary doesn't? The treasurer is specifically accountable for financial accuracy and legal filings. The president runs meetings and represents the group. The secretary keeps minutes. The treasurer is the one who signs off, literally or practically, on whether the organization's money is where it should be and whether the group is still in good standing with the IRS and the state.
How does 990-N filing fit into a treasurer's yearly calendar?
For most booster clubs and PTOs, the 990-N should be one of maybe four fixed dates a treasurer tracks all year, alongside your state's annual corporate/nonprofit report (if your state requires one), your state charity registration renewal (if fundraising publicly requires one, confirm with your state charity office), and your fiscal year-end financial reconciliation. Build a simple recurring reminder, ideally two: one 60 days before your 990-N deadline, one the week of. A missed 990-N in year one is a minor annoyance. A missed 990-N in years one, two, and three is an automatic revocation with real consequences, so the second reminder matters more than it sounds like it should. A lot of the pain here isn't the filing itself, it's not knowing your fiscal year end, not knowing your EIN, or not knowing which officer is supposed to be the one filing, because the treasurer changed twice since the last filing and nobody wrote anything down. That's a handoff problem more than a tax problem, and it's worth building a simple binder or folder that travels with the role every time a new volunteer takes over: EIN, fiscal year end, last filing confirmation, bank account details, and the state charity registration status all in one place.
Does filing Form 990-N cost anything, and do you need an accountant?
Form 990-N is free to file and most treasurers can do it themselves in under 15 minutes without hiring anyone. There's no tax owed, no schedules to prepare, no signature required from a CPA. Where it gets more complicated: if your organization's gross receipts have grown past $50,000 and you now need the 990-EZ or full 990, that's a genuinely different job, and a lot of volunteer treasurers do reach for a bookkeeper or accountant at that point, which is a reasonable call given the stakes of getting a public financial filing wrong. If you inherited a booster club or PTO's books mid-year and you're not sure whether the group's exemption is even current, that's worth checking before you file anything. The IRS Tax Exempt Organization Search tool lets you look up your organization's filing history and current exempt status for free, and it's the fastest way to find out if a prior treasurer already let the exemption lapse [8].
What should a new treasurer do first if they've never filed a 990-N?
Find your EIN, confirm your fiscal year end, and check the IRS Tax Exempt Organization Search to see your organization's last filed year before you do anything else. If the last filing was more than a year ago, that's your first priority, not next month's fundraiser. If you can't find an EIN or exempt status at all, your organization may have never applied for exemption in the first place, or it may already be auto-revoked, both of which are common in booster clubs that formed informally years ago and never formalized paperwork. That's a bigger project than filing a 990-N, and it's worth confirming your organization's actual status with the IRS and, if you plan to raise money publicly through raffles or similar activities, with your state charity office, before assuming a quick e-Postcard fixes everything. This is genuinely one of the areas where a small, organized starting kit saves a new volunteer treasurer real hours of guesswork. BoosterLedger's $99 one-time State-Personalized Treasurer Kit walks a new treasurer through exactly this sequence, EIN, exempt status check, fiscal year, filing deadline, state-specific requirements, built for the state you're actually operating in, not a generic national template.
Where do you go for help or to double-check your filing status?
The IRS's own e-Postcard page is the authoritative source for filing mechanics and thresholds, and it's kept current with the actual gross receipts figures [1]. The IRS Exempt Organizations customer account services line can also answer status questions if you're stuck, though wait times during peak filing season can be long. For anything involving state-level requirements, like whether your booster club also needs to register with a state charity regulator before running a raffle or public fundraiser, that's a separate check with your specific state's attorney general or secretary of state charity division, since those rules vary widely and change periodically. Nothing in this article is tax or legal advice, and BoosterLedger isn't an accounting or law firm; when your situation gets complicated (large gross receipts, a lapsed exemption, multi-state fundraising) it's worth a real conversation with a CPA or attorney who works with nonprofits.
Frequently asked questions
What is Form 990-N used for?
Form 990-N, the IRS e-Postcard, confirms a small tax-exempt organization still exists and still qualifies as tax-exempt. It reports basic identifying information (EIN, address, officer name, tax year) rather than financial detail, and it's required annually of most organizations with gross receipts normally $50,000 or less [1].
What is Form 990?
Form 990 is the IRS's annual information return for tax-exempt organizations. Depending on size, an organization files the full Form 990, the shorter Form 990-EZ, or the e-Postcard Form 990-N. All three are public filings; the full 990 includes detailed financial statements, while the 990-N is just eight basic data fields.
What is the 990 tax form, exactly?
It's not really a "tax" form in the traditional sense since most filers owe no tax with it; it's an annual information return the IRS requires from tax-exempt organizations to confirm they still qualify for exemption and to disclose (at larger sizes) financial activity to the public.
Who is required to file Form 990-N?
Tax-exempt organizations whose gross receipts are normally $50,000 or less per year must file the 990-N unless they file the 990-EZ or full 990 voluntarily, or fall under a specific exception like churches [1][2]. Most small booster clubs, PTOs, and youth sports groups fall into the 990-N category.
When is Form 990-N due each year?
It's due by the 15th day of the 5th month after your organization's fiscal year ends. For a calendar-year organization (Jan-Dec), that's May 15. For a July-June fiscal year, common among school-affiliated groups, that's November 15 [3].
What happens if a nonprofit doesn't file Form 990-N for three years?
The organization's tax-exempt status is automatically revoked by operation of law, per the Pension Protection Act of 2006 [4]. No warning letter is required before revocation. Reinstatement requires filing Form 1024 or 1024-A and possibly back 990s, and can take months.
Can you file Form 990-N late?
Yes, and there's no late-filing penalty attached to the 990-N itself, unlike the full 990. But it still counts toward the three-consecutive-year rule; filing late for years one and two, then catching up, resets that clock and avoids automatic revocation.
Is there an extension for Form 990-N?
No. Unlike the full Form 990, which can get a six-month extension via Form 8868, the 990-N has no extension mechanism [5]. If you're late, just file it as soon as possible; there's nothing to formally extend.
What does a treasurer do in a club or PTO?
A treasurer manages the organization's money: deposits and disbursements, bank reconciliation, budget tracking, recordkeeping, and required filings like the annual 990-N. In volunteer-run clubs, the treasurer is often the sole person with regular access to the bank account and the sole one responsible for IRS compliance.
How much does it cost to file Form 990-N?
Nothing. Filing Form 990-N through the IRS's online system is free, takes about 10 to 15 minutes, and requires no professional preparer for most small organizations, since there are no financial statements to prepare.
How do I know if my organization's gross receipts qualify for 990-N?
The IRS uses a rolling average: new organizations (year one) qualify at $75,000 or less; two-year-old organizations average current plus prior year at $60,000 or less; organizations three years or older average the current year plus the two before it at $50,000 or less [1].
Where do I check if my nonprofit's exemption has already been revoked?
Use the IRS Tax Exempt Organization Search tool, free on IRS.gov, which shows current exempt status, filing history, and whether an organization appears on the automatic revocation list [8]. It's the fastest way for a new treasurer to check inherited books before filing anything.
Does Form 990-N filing information become public?
Yes, all Form 990 series filings, including 990-N, are public. Anyone can search the IRS Tax Exempt Organization Search or nonprofit data sites to see whether and when an organization filed, though the 990-N itself contains very little detail beyond confirming the filing happened.
