TL;DR
Form 990-N, nicknamed the e-Postcard, is the free IRS filing for tax-exempt organizations with $50,000 or less in gross receipts. You file it online at irs.gov, it takes about 8 to 10 minutes, and there's no paper version and no cost. Miss it three years running and the IRS auto-revokes your exempt status.
What is Form 990-N (the e-Postcard)?
Form 990-N is the smallest, simplest version of the annual information return that tax-exempt organizations file with the IRS. The IRS calls it the "e-Postcard," and that name isn't marketing fluff, it really is that short. You're not reporting income statements or program expenses. You're confirming eight basic facts about your organization and hitting submit. Any organization normally required to file an annual return, but whose gross receipts are $50,000 or less, can file the e-Postcard instead of the longer Form 990 or 990-EZ [1]. That threshold matters a lot for booster clubs and PTOs, because most small ones fall well under $50,000 in a typical year. The form only exists in electronic form. There is no paper 990-N. You file it through the IRS's own site, not through commercial tax software, and it's free every single time [2]. If someone tries to charge you real money to file a 990-N, you're paying for convenience or hand-holding, not for something the IRS requires you to buy. If your organization has never filed anything with the IRS before, or you're not sure what you filed last year, start by reading up on form 990 generally so you understand where 990-N sits relative to the full 990 and the 990-EZ.
What is Form 990? (and how is the 990-N different)
| 990-N (e-Postcard) | Gross receipts normally $50,000 or less | 8 questions, online only | |
|---|---|---|---|
| 990-EZ | Gross receipts under $200,000 and total assets under $500,000 | Several pages, financial detail | |
| 990 (full) | Gross receipts $200,000 or more, or assets $500,000 or more | Full financial statements, extensive detail | These thresholds come straight from the IRS's own instructions and its annual return filing requirements page [4]. A booster club running concession stands and a couple fundraisers a year is very often a 990-N filer. A district-wide PTO council with a paid coordinator and a five-figure budget might have crossed into 990-EZ territory without anyone noticing, which is a conversation worth having with whoever kept the books before you. If you're trying to figure out which one applies to your group, our explainer on the 990 tax form walks through the thresholds in more detail, and the irs form 990 overview covers what's actually on the full form if you ever grow into it. |
Form 990 is the IRS's annual information return for tax-exempt organizations, the document that reports income, expenses, program activities, and governance details to the public and the IRS [3]. Think of it as the nonprofit world's version of an annual report crossed with a tax return, except most small exempt organizations don't owe any tax. There are really three tiers, based on gross receipts and total assets: | Form | Who files it | Complexity |
Who has to file the 990-N e-Postcard?
You have to file some version of the 990 series if your organization is recognized as tax-exempt (or operates as one) and its gross receipts are normally $50,000 or less, unless you fall into a specific exception [1]. "Normally" is an IRS term of art: it means averaged over the current year and the prior two years, more than this year's number in isolation. A few groups are exempt from filing at all: churches and their integrated auxiliaries, and organizations included in a group return, are among the exceptions the IRS lists [1]. Most independent booster clubs, parent-teacher organizations, and youth sports leagues don't qualify for those exceptions. If you have your own EIN and your own 501(c)(3) or 501(c)(4) recognition (or you're operating as an unincorporated association claiming exemption), you almost certainly owe an annual filing of some kind. Here's the trap: a lot of small booster treasurers assume that because they don't owe any tax, they don't have to file anything. That's wrong, and it's the single most common reason small nonprofits get auto-revoked. Filing requirement and tax liability are two different things. You can owe zero dollars in tax and still be required to file the e-Postcard every year. If you inherited a group and have no idea what's been filed historically, the IRS's Tax Exempt Organization Search tool lets you look up an organization's filing history by name or EIN, which is the fastest way to find out where things stand [5].
How do you file the 990-N e-Postcard, step by step?
You file directly on the IRS website, and the whole process is designed to take under 15 minutes if you have your basic organizational facts handy. The IRS's own FAQ page describes the filer as any "officer, director, trustee, or other individual who is authorized to file the notice on behalf of the organization" [1]. What you need before you start: Your organization's legal name and any "doing business as" name. Your Employer Identification Number (EIN), not a Social Security number. Your tax year (usually the calendar year for most small groups, but check your bylaws). The name and address of a principal officer. Your website address, if you have one. A statement confirming your gross receipts are normally $50,000 or less. Confirmation that the organization is not in bankruptcy or has not been liquidated, dissolved, or terminated. That's basically the whole form. Eight items, no financial statements, no schedules. You submit it electronically through the IRS's own online filing system, and you'll get an on-screen confirmation, though it can take a while for a filing to show as accepted in the IRS's public search tool [1]. One practical tip: file early in your filing window rather than waiting until the deadline. If something bounces (wrong EIN, name mismatch with IRS records), you want time to fix it before you're staring down a revocation clock.
When is Form 990-N due?
The e-Postcard is due by the 15th day of the 5th month after your organization's accounting period ends [1]. For a group on a calendar fiscal year (January 1 to December 31), that means the filing is due May 15 of the following year. There's no extension form for the 990-N specifically, and honestly, you don't usually need one. Because the form takes minutes to complete, most treasurers who miss the deadline missed it because they didn't know it existed, not because they ran out of time to gather data. The IRS's own FAQ confirms there's no penalty assessed for late-filing the e-Postcard itself [1], but lateness still counts toward the three-year revocation clock described below, so don't treat the lack of a penalty as license to ignore it. Mark the date on whatever calendar your board actually uses. Not a folder nobody opens. If your fiscal year isn't the calendar year, the due date shifts, so confirm your actual fiscal year end with your bylaws or your predecessor treasurer before you assume May 15 applies to you.
What happens if you don't file the 990-N?
The IRS's rule here is blunt and unforgiving: an organization that fails to file required 990-series returns (including the e-Postcard) for three consecutive years automatically loses its tax-exempt status, by operation of law, no notice required beyond what's already been published [6]. This isn't a warning system where the IRS calls you first. The revocation happens on the filing due date of the third missed year. The IRS states plainly that "organizations that fail to file required returns for three consecutive years will automatically lose their tax-exempt status" and that reinstatement requires re-applying [6]. Once revoked, your donations are no longer automatically tax-deductible to donors, and depending on your state, you may need to re-register with your state charity office or attorney general as well, since state exemption often piggybacks on federal status. The fix, if you've been auto-revoked, is filing for reinstatement, typically using Form 1023 or 1023-EZ again along with a reasonable cause statement, and in many cases you can request retroactive reinstatement back to the revocation date under Revenue Procedure 2014-11 if you file within the window it specifies. That's a real project, not a 10-minute form, and it usually benefits from getting your board together and being honest about what happened before you start. If you're not sure whether your organization has already been auto-revoked, check the IRS's Tax Exempt Organization Search tool [5], which lists organizations that have lost exemption this way. Confirm with the IRS and a qualified advisor before assuming reinstatement details apply exactly to your situation, since procedures do get updated.
What does a treasurer do (and how does the 990-N fit in)?
A treasurer's core job is keeping the organization's money honest and keeping its paperwork current, and filing the annual IRS return is one of maybe five or six recurring duties that make up the role. If you just took over a booster club or PTO's books, the 990-N is very likely one of your first concrete tasks, and it's a good one to knock out early because it's fast and it builds confidence. In practical terms, what does a treasurer do in a club? Usually: track income and expenses (concessions, dues, fundraiser proceeds), reconcile the bank account monthly, present a budget or financial report at meetings, manage check signing and approval controls, and handle the annual IRS filing, whichever version applies. Some treasurers also handle state charitable registration renewals and raffle licensing paperwork if the group runs raffles. What does a club treasurer do differently from, say, a corporate treasurer? Scale, mostly. A club treasurer of a $15,000-a-year booster program is doing the same fundamental job (accurate records, on-time filings, controls against theft or error) as a treasurer of a much bigger organization, just with fewer transactions and usually zero staff support. That's actually the tricky part: you're doing a real financial-oversight job with no bookkeeper and no compliance department behind you. What does a treasurer of a club do that a general board member doesn't? Signature authority on the bank account, custody of financial records, and personal familiarity with the organization's EIN, fiscal year, and filing history, since you're often the only person who knows those facts off the top of your head. That's exactly the information the e-Postcard asks for, which is why the treasurer is almost always the one who files it.
What is a treasurer, exactly, in a small nonprofit?
A treasurer is the officer legally and practically responsible for an organization's money: receiving it, recording it, safeguarding it, reporting on it, and making sure required filings happen on time. In most small booster clubs and PTOs, the treasurer is an elected volunteer position, not a paid staff role, and turnover happens every year or two as parents rotate off boards when their kids graduate or move up a level. That turnover is actually the biggest risk factor around 990-N filing. A club can go three years without anyone filing the e-Postcard simply because treasurer #1 filed it, treasurer #2 didn't know it existed, and treasurer #3 inherited a mess with no idea what happened before them. The IRS's three-strikes revocation rule doesn't care why nobody filed. It just runs the clock. If you're new to the role, the honest first move is a records audit: pull bank statements, find the EIN, check the IRS search tool for filing history, and confirm your fiscal year. Do that before you worry about budgets or fundraisers. Everything else in the treasurer job depends on knowing where the organization actually stands with the IRS and your state. We put together a state-personalized kit for exactly this situation ($99 one-time, at /treasurer-kit-builder), which walks new treasurers through the EIN lookup, the 990-N filing itself, and the state-specific charity registration and raffle licensing steps that often get missed because they're not on the IRS's radar at all.
What is a 990 tax form used for, beyond just staying compliant?
Beyond keeping your exemption alive, the 990-series filings are public documents. Anyone, including donors, grant funders, and journalists, can look up your organization's filings through the IRS's search tool or through nonprofit databases that mirror IRS data [5]. A clean, on-time filing history is a small but real credibility signal when you're asking a local business for a sponsorship or applying for a community grant. The form also forces a moment of institutional memory. Filling out even the short e-Postcard means confirming your EIN, your legal name, your principal officer, and your gross receipts once a year, which catches drift before it becomes a real problem, like a bank account still tied to a departed treasurer's login, or a legal name mismatch between what's on your IRS records and what's on your bank paperwork. For groups that eventually cross the $50,000 gross receipts threshold, whether from a one-time windfall fundraiser or steady growth, filing history also determines which form you should have been on. If you filed a 990-N last year but blew past $50,000 this year, you'll likely need to step up to a 990-EZ or full 990 for the current year, so it's worth checking your running three-year average gross receipts every filing season rather than just looking at last year's number [4].
990-N vs 990-EZ vs full 990: which one do you actually file?
| Gross receipts normally ≤ $50,000 | 990-N (e-Postcard) | 8-10 minutes | |
|---|---|---|---|
| Gross receipts < $200,000 AND total assets < $500,000 | 990-EZ | Several hours, often with help | |
| Gross receipts ≥ $200,000 OR total assets ≥ $500,000 | Full 990 | Days, usually with an accountant | "Normally" for the 990-N threshold is based on a rolling average, not a single year, so a single unusually large fundraiser doesn't necessarily bump you up if your typical years run well under $50,000 [1]. But if you've had two strong years in a row, run the average and see where you land before you default back to the e-Postcard out of habit. If you're unsure which form fits, our comparison of the [990](/articles/treasurer-basics/990), 990-EZ, and full [990](/articles/treasurer-basics/990) breaks the thresholds down further, and the 990n and form 990-n pages go deeper into the e-Postcard's specific eight data fields if you want to see exactly what you'll be typing before you sit down to file. |
Most booster clubs and PTOs live comfortably in 990-N territory, but it's worth double-checking rather than assuming, especially after a big fundraising year. Here's the practical breakdown, based on the IRS's own filing thresholds [4]: | Situation | Form | Roughly how long it takes |
What if you're not sure your organization is even tax-exempt?
This happens more often than you'd think, especially with booster clubs that formed informally years ago and never got a clean paper trail. If nobody can produce a determination letter or you can't find your organization in the IRS's search tool at all, you may not actually be a recognized 501(c)(3) or 501(c)(4), you might just be an informal group operating under a school's umbrella or an old EIN with no exemption attached. Start with the IRS Tax Exempt Organization Search [5]. Search by name and by EIN if you have one. If nothing comes up, or what comes up shows "Auto-Revoked," you're not in a position to just file a 990-N and call it fixed, you likely need to either apply fresh (Form 1023 or 1023-EZ) or go through reinstatement procedures [6]. This is one of those situations where paying for an hour of a local nonprofit-focused accountant's time is worth it before you guess. Confirm with the IRS and your state charity office directly rather than assuming your predecessor's paperwork was complete, since the cost of getting it wrong (losing exemption, or worse, discovering you never had it) is much higher than the cost of a short consult.
Frequently asked questions
What is Form 990-N (the e-Postcard)?
Form 990-N is the shortest IRS annual filing for tax-exempt organizations with gross receipts normally $50,000 or less. It's filed online only, has eight basic questions, costs nothing, and takes most treasurers under 15 minutes to complete once they have their EIN and basic organization details ready [1][2].
Is filing Form 990-N really free?
Yes. The IRS provides the e-Postcard filing system directly, with no fee to submit [1]. If a company charges you to file a 990-N on your behalf, you're paying for their convenience service, not an IRS-required fee. Many small booster treasurers file it themselves in one sitting without any paid help.
What is Form 990?
Form 990 is the IRS's general annual information return for tax-exempt organizations, covering income, expenses, and governance details [3]. It comes in three sizes based on gross receipts and assets: the 990-N e-Postcard for the smallest organizations, the 990-EZ for mid-size groups, and the full Form 990 for larger nonprofits [4].
What happens if I miss the 990-N deadline?
A single late e-Postcard doesn't carry a monetary penalty the way late 990-EZ or full 990 filings can [6], but it still counts against the IRS's three-consecutive-year rule. Miss three years in a row and your organization automatically loses its tax-exempt status, no advance warning required [7].
When is the 990-N due?
It's due the 15th day of the 5th month after your fiscal year ends [1]. For calendar-year organizations (most booster clubs and PTOs), that's May 15. Check your bylaws for your actual fiscal year end before assuming that date applies, since some groups run on a school-year fiscal cycle instead.
What does a treasurer do in a club or booster organization?
A treasurer tracks income and expenses, reconciles the bank account, reports finances to the board, manages check-signing controls, and handles required IRS and state filings, including the annual 990-series return. In small volunteer organizations, the treasurer is usually the only person who knows the EIN and filing history off the top of their head.
What does a treasurer of a club do differently from other board members?
The treasurer typically holds signature authority on the bank account, custody of financial records, and responsibility for annual filings like the 990-N. Other board members vote on budgets and programs, but the treasurer is the one who actually executes the money-handling and compliance tasks day to day.
How do I know if my organization qualifies for the e-Postcard instead of a longer form?
Check whether your gross receipts, averaged over the current year and prior two years, are normally $50,000 or less [1][4]. If yes, you likely qualify for the 990-N. If you've crossed $200,000 in receipts or $500,000 in assets in a given year, you need the 990-EZ or full 990 instead.
Can churches or small groups skip filing entirely?
Some organizations, including churches and their integrated auxiliaries, and groups included under another organization's group return, are excepted from the annual filing requirement [1]. Most independent booster clubs and PTOs with their own EIN don't fall into these exceptions and do need to file something every year.
What happens after three years of not filing?
The IRS automatically revokes tax-exempt status after three consecutive years of missed required filings, with no separate notice needed beyond the published rule itself [7]. Reinstatement means reapplying for exemption, often with Form 1023 or 1023-EZ, and possibly requesting retroactive reinstatement under IRS-specified procedures.
How do I check if my organization has already been auto-revoked?
Use the IRS Tax Exempt Organization Search tool at irs.gov, searching by your organization's legal name or EIN [5]. It lists current exempt status and shows organizations that have lost exemption through automatic revocation, along with links to filed 990-series returns where available.
Does filing the 990-N mean my organization owes taxes?
No. Filing an annual return and owing tax are separate questions. Most 990-N filers are exempt organizations with no tax liability at all; the filing simply confirms basic facts to keep your exempt status current. Confirm your specific tax situation with the IRS or a qualified advisor if you're unsure.
What information do I need before I sit down to file the e-Postcard?
Your legal organization name and any DBA, your EIN, your tax year, a principal officer's name and address, your website if you have one, and confirmation that gross receipts are normally $50,000 or less and the organization isn't dissolved or in bankruptcy [1][6]. That's the complete list.
