Form 990-n requirements: who must file and how

Last updated 2026-07-24

What is Form 990-N?

Form 990-N, officially called the e-Postcard, is the shortest of the IRS's annual information returns for tax-exempt organizations. It's not really a form in the traditional sense. There's no PDF to fill out and mail in. You log into an IRS-linked system and enter eight pieces of information: your EIN, tax year, legal name and mailing address, any other names the group uses, the name and address of a principal officer, your website if you have one, confirmation that gross receipts are $50,000 or less, and a statement that the organization hasn't terminated ^[1]. The IRS created 990-N in 2007 because Congress, through the Pension Protection Act of 2006, required small tax-exempt organizations to file something annually for the first time. Before that, groups under $25,000 in gross receipts had no federal filing requirement at all. That silence is exactly why so many small booster clubs and PTOs lost their exempt status a few years later: they'd never had to file anything, so nobody thought to start ^[2]. If you're new to booster club or PTO finances and keep seeing "990," "990-EZ," and "990-N" thrown around interchangeably, they're related but not the same. The 990 tax form family has three main tiers based on money in and assets, and 990-N is the bottom tier for the smallest organizations.

Who has to file Form 990-N?

Most small tax-exempt organizations recognized under Internal Revenue Code Section 501(a), including 501(c)(3) groups, must file 990-N if their gross receipts are normally $50,000 or less. The IRS states it plainly: "Most small tax-exempt organizations whose annual gross receipts are normally $50,000 or less" file the e-Postcard unless they choose to file a complete Form 990 or 990-EZ instead ^[1]. "Normally" is the tricky word here, and it matters for treasurers doing the math after a big fundraiser year. The IRS doesn't look at just your most recent year. It uses averages: for organizations in their first year, gross receipts of $75,000 or less qualify; for organizations that have existed one to three years, the average of the first two or three years must be $60,000 or less; for organizations three years old or more, the average of the immediately preceding three tax years must be $50,000 or less ^[1]. That averaging rule saves a lot of booster clubs that have one unusually good year, maybe a big raffle or a capital campaign for new uniforms. If your three-year average still lands at $50,000 or under, you're fine to file 990-N even if last year alone hit $70,000. Organizations that aren't required to have an EIN yet, or that are included in a group return, don't file 990-N separately. Private foundations never file 990-N regardless of size; they file Form 990-PF. Section 527 political organizations have their own filing rules too ^[1].

What is Form 990, and how is it different from 990-N?

990-N (e-Postcard)	Smallest exempt orgs	Normally $50,000 or less [1]	Free
990-EZ	Small-to-mid exempt orgs	Under $200,000, assets under $500,000 [1]	Free to file, may need paid preparer help
990 (full)	Larger exempt orgs	$200,000+ or assets $500,000+ [1]	Free to file, usually needs a preparer
990-PF	Private foundations	Any size	Free to file, usually needs a preparer	For a side-by-side breakdown of what's actually on each version, see irs form 990 and [990](/articles/treasurer-basics/990).

Form 990 is the umbrella name for the IRS's annual information return for tax-exempt organizations. There are three main versions, chosen by size, not by choice alone. The full Form 990 is required once gross receipts hit $200,000 or total assets hit $500,000. Form 990-EZ sits in the middle, for organizations with gross receipts under $200,000 and total assets under $500,000. Form 990-N is the bottom tier, for gross receipts normally $50,000 or less ^[1]. Here's the part that trips people up: you can always choose to file a longer form even if you qualify for 990-N. Some treasurers do this on purpose, because a full 990 or 990-EZ shows more financial detail to a bank, a school district, or a state charity regulator asking for proof of good standing. But you cannot go the other direction. If your gross receipts exceed the 990-N threshold, filing the e-Postcard instead of the required 990 or 990-EZ doesn't satisfy your obligation and can itself trigger problems. | Form | Who files it | Gross receipts threshold | Cost to file |

How do you actually file Form 990-N?

You file 990-N electronically through the IRS's own online system. As of the current IRS guidance, e-Postcard filing happens through IRS.gov, where the agency migrated the filing system from the older Urban Institute-hosted site in 2016 ^[1]. There's no cost. There's no software to buy. You need your organization's EIN, tax year end date, legal name, and the contact information listed above. Most treasurers who've done this once say it takes under 15 minutes, assuming they have the EIN and basic org details on hand. If you've just taken over the books and don't know the organization's EIN, check old bank statements, a prior year's IRS determination letter, or call the IRS Exempt Organizations customer account line. One practical note for volunteer treasurers rotating in and out every year or two: whoever filed last year's 990-N may have used a personal email address that's no longer active. That's fine. The filing itself doesn't depend on a login history; you can file fresh each year as the current "principal officer" without needing access to a prior account. Just make sure the mailing address and officer name reflect who's actually running things now.

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 tax year. For a calendar-year organization (tax year ending December 31), that's May 15 of the following year ^[1]. If your fiscal year ends June 30, like many school-affiliated booster clubs and PTOs, your 990-N is due November 15. There's no paper extension form for 990-N specifically, and importantly, there's no late penalty from the IRS for filing 990-N late in a given year ^[1]. That surprises people. Unlike a 990 or 990-EZ, where the IRS can assess dollar penalties per day for late filing, the e-Postcard has no such monetary penalty structure. But don't read "no penalty" as "doesn't matter." The consequence for 990-N isn't a fine, it's revocation, and that's a much bigger problem than a late fee.

What happens if you miss the Form 990-N deadline?

Miss it once, and generally nothing happens immediately, since there's no per-year penalty. Miss it three consecutive years, and the law is unforgiving: the IRS states that an organization that fails to file required Form 990-series returns for three consecutive years automatically loses its tax-exempt status, a result required by federal law (the Pension Protection Act of 2006, IRC Section 6033(j)) ^[3]. This is automatic. There's no warning notice sent before it happens, no hearing, no appeal process that stops it retroactively. The revocation date is the filing due date of the third consecutively missed year. Since 2007, over 760,000 organizations have had their exempt status automatically revoked under this rule, based on IRS revocation list data compiled over the years the rule has been in effect ^[4]. A large share of those are exactly the kind of small, all-volunteer booster clubs and PTOs that never had to file anything before 2007 and simply didn't know the rule changed. Once revoked, the organization is treated as a taxable entity going forward, loses eligibility for tax-deductible donations, and its name appears on the IRS's public Tax Exempt Organization Search revocation list. Getting reinstated means filing Form 1023 (or 1023-EZ for smaller orgs) again, often with reduced user fees available for organizations that qualify for streamlined retroactive reinstatement within 15 months of revocation ^[5]. It's fixable. It's just a real project, not a quick form.

What does a treasurer do?

A treasurer is the officer responsible for an organization's money: tracking it, protecting it, reporting on it, and making sure the group meets its legal filing obligations. In a volunteer booster club, PTO, or youth sports league, that usually means one person wearing several hats that a larger nonprofit would split among a bookkeeper, a controller, and a compliance officer. Day to day, what does a treasurer do? Concretely: deposit cash and checks from fundraisers promptly, keep a running ledger of income and expenses, reconcile the bank statement every month, pay approved bills, keep receipts organized for every purchase, and report account balances at board or membership meetings. Annually, the treasurer's job expands to include the tax side: confirming the group's EIN is active, determining whether 990-N, 990-EZ, or full 990 applies based on that year's gross receipts, and filing (or handing off to a paid preparer) by the deadline. What does a treasurer do in a club more specifically, versus a full nonprofit? The core job is the same, but a club treasurer often also handles member dues tracking, fundraiser cash counts with a second counter present, and coordinating with a board on spending approval limits. What does a club treasurer do that's different from a corporate finance role: there's rarely a paid staff, so the treasurer is also the one physically depositing the cash box from Friday's concession stand and reconciling it against the tally sheet. See treasurer-basics for the fuller job description and handoff checklists.

What is a treasurer, exactly, and what does a treasurer of a club do?

A treasurer is an elected or appointed officer, usually named in the organization's bylaws, who holds legal and practical responsibility for the group's funds. It's a fiduciary role: the treasurer isn't just doing bookkeeping as a favor, they're accountable to the board and, in a tax-exempt organization, indirectly accountable to the IRS and to the state charity regulator for accurate financial reporting. What does a treasurer of a club do when there's no professional accountant involved? In practice, it means the treasurer is the single point of contact for anyone asking "how much money do we have" or "can we afford this." It means keeping bank statements, deposit slips, and receipts in a way that a new treasurer could pick up and understand a year later. It means never being the only person who touches both the cash and the books; even in a two-person volunteer board, someone else should review the bank statement or count fundraiser cash alongside the treasurer. The treasurer is also usually the person who has to explain a filing gap to a new board when auto-revocation shows up. That's an uncomfortable conversation to have without documentation showing what happened and when, which is one more reason to keep clean year-over-year records from day one.

What is a 990 tax form, and why does a small club need to bother?

A 990 tax form is the IRS's mechanism for making tax-exempt organizations publicly accountable even though they don't pay income tax. Because these groups get the benefit of exemption and, for 501(c)(3)s, the ability to accept tax-deductible donations, the IRS (and the public) gets visibility into how the money moves. The IRS itself frames it this way: exempt organizations generally must file annual returns, a requirement in place even if the organization has not yet received a determination letter recognizing exemption in some cases ^[6]. For a small booster club running concession stands and a spring raffle, the honest answer to "why bother" is: because the alternative is losing exempt status, and getting it back costs real time and sometimes real money in reinstatement fees. It also matters to your bank, your school district, and any grant funder who asks for proof of good standing; a lapsed or revoked status shows up immediately on IRS.gov's Tax Exempt Organization Search. Check the IRS's 990n explainer for the plain-language walk-through of the e-Postcard itself, and 990-tax-form for how the three tiers compare on required detail.

What is the 990, and does every nonprofit really have to file one?

"The 990" is shorthand people use for whichever version of the annual return applies to their organization. Nearly every tax-exempt organization recognized under Section 501(a) has to file some version every year, whether that's the e-Postcard, the EZ, the full form, or the 990-PF for private foundations. There are narrow exceptions: churches and certain church-affiliated organizations are generally not required to file an annual return at all, though they can file voluntarily ^[7]. For everyone else, including booster clubs, PTOs, and youth sports associations organized as 501(c)(3) public charities, the filing requirement is not optional and not tied to whether the group made any real money that year. A booster club that took in $8,000 from a car wash and a bake sale still has to file 990-N if it's recognized as tax-exempt, even though $8,000 sounds too small to bother the IRS about. The gross receipts threshold determines which version you file, not whether you file at all.

How do you check whether your organization is already revoked?

Use the IRS Tax Exempt Organization Search tool at IRS.gov and search by your organization's name or EIN. The tool includes a specific "Auto-Revocation" list that shows organizations that lost exempt status for failing to file for three consecutive years, along with the revocation date ^[5]. This is the first thing a new treasurer should check, before doing anything else with the books. If your group shows up on that list, the practical next step is reinstatement, generally by filing Form 1023 or Form 1023-EZ with the IRS. Organizations that apply within 15 months of the revocation posting date and meet other conditions may qualify for the streamlined "retroactive reinstatement" process the IRS describes in its guidance, which can restore exempt status back to the original revocation date without a filing gap for donors ^[5]. Miss that 15-month window and the process gets more involved, generally requiring a written statement of reasonable cause for the missed filings. This is genuinely one area where getting outside help pays for itself. A CPA or attorney familiar with exempt organization reinstatement can often move faster and more accurately than a volunteer doing it for the first time, and mistakes on the reinstatement application can cost more time than they save.

What records should a treasurer keep to make 990-N filing easy every year?

The e-Postcard itself asks for very little, but you can't answer "are gross receipts normally $50,000 or less" honestly without decent books. At minimum, keep a running income and expense ledger updated monthly, bank statements and reconciliations for every month, and a simple year-end summary showing total gross receipts for the year. Build a one-page handoff sheet each year with the EIN, the tax year end date, the current principal officer's name and address, and the date the 990-N was filed and confirmed accepted. Confirmation matters: the IRS system gives you an acceptance notice when the e-Postcard goes through, and that confirmation is worth saving as a PDF or screenshot, filed alongside the year's bank statements. Many volunteer treasurers rotate out after one or two years, and the single biggest cause of missed filings isn't laziness, it's simply nobody telling the incoming treasurer that this obligation exists. A written procedures binder, even a simple one, solves most of this. Some groups put together a full state-personalized kit covering the EIN, filing history, deadline calendar, and reinstatement steps specific to their state's charity registration rules; if you want a starting structure rather than building one from scratch, a $99 one-time State-Personalized Treasurer Kit exists for exactly that handoff gap.

Does the state care about your 990-N too, or is this purely federal?

Form 990-N itself is a federal IRS filing, but most states with charitable solicitation registration requirements ask for a copy of your most recent IRS annual return, whatever tier applies, as part of annual state charity registration renewal. Some states also independently revoke state charitable status if federal exempt status lapses. Requirements vary a lot by state, and thresholds, forms, and fees change, so confirm current rules with your state's charity registration office or attorney general's charities bureau before assuming your 990-N filing alone covers you. A booster club that only files 990-N federally but skips a required state charitable solicitation registration can still end up out of compliance at the state level even with a clean IRS record. When in doubt, call your state attorney general's charities division or check their nonprofit registration page directly rather than guessing based on what a neighboring booster club does. State rules genuinely differ enough that copying another group's process isn't a safe shortcut.

Frequently asked questions

What is Form 990-N used for?

Form 990-N, the e-Postcard, is the annual IRS information return for tax-exempt organizations with gross receipts normally $50,000 or less. It confirms basic identifying information (EIN, name, address, principal officer) and that the organization is still operating, satisfying the annual filing requirement created by the Pension Protection Act of 2006 ^[2][3].

Is Form 990-N free to file?

Yes. Form 990-N is filed electronically through IRS.gov at no cost. There's no filing fee, no paid software required, and no paper version to mail. It generally takes under 15 minutes if you have your EIN and officer information ready ^[1][4].

What happens if you never file Form 990-N?

Nothing happens after one missed year since there's no monetary penalty for late 990-N filing. But if you fail to file for three consecutive years, the IRS automatically revokes your tax-exempt status by law, no notice required ^[5][6].

Who is required to file Form 990-N?

Tax-exempt organizations under Section 501(a) with gross receipts normally $50,000 or less, unless they choose to file a full 990 or 990-EZ instead. Private foundations and Section 527 political organizations don't use 990-N; churches are generally exempt from the annual filing requirement altogether ^[1][10].

What is the deadline for Form 990-N?

The 15th day of the 5th month after your organization's tax year ends. Calendar-year organizations file by May 15; groups on a July 1 to June 30 fiscal year (common for school-affiliated PTOs) file by November 15 ^[1].

What is a treasurer?

A treasurer is the officer responsible for an organization's finances: tracking income and expenses, reconciling bank accounts, paying bills, reporting balances to the board, and handling annual tax filings like Form 990-N. It's usually a bylaws-defined, elected position with fiduciary duty to the group.

What does a treasurer do in a club or booster organization?

Day to day: deposits fundraiser cash, keeps a ledger, reconciles the bank statement monthly, pays approved bills, and keeps receipts organized. Annually: determines which IRS form applies based on gross receipts and files it, and checks that state charity registration, if required, stays current.

What is Form 990?

Form 990 is the IRS's family of annual information returns for tax-exempt organizations, with three main tiers based on gross receipts and assets: the full Form 990, Form 990-EZ, and Form 990-N (e-Postcard) for the smallest groups ^[3].

What is the difference between Form 990 and Form 990-N?

Form 990 is the full-length annual return required once gross receipts hit $200,000 or assets hit $500,000; it asks for detailed program, revenue, and compensation information. Form 990-N is an 8-item electronic confirmation for organizations with gross receipts normally $50,000 or less, with no financial detail required ^[3][1].

Can a small nonprofit choose to file the full Form 990 instead of 990-N?

Yes. Any organization eligible for 990-N can voluntarily file the longer 990-EZ or full 990 instead, often to show more detail to a bank, funder, or school district. You cannot go the other way; if gross receipts exceed the 990-N threshold, filing the e-Postcard doesn't satisfy the requirement.

How do I know if my organization already lost its tax-exempt status?

Search your organization's name or EIN in the IRS Tax Exempt Organization Search tool at IRS.gov, which includes a specific Auto-Revocation list showing organizations that lost status for missing three consecutive annual filings, along with the revocation date ^[8].

How do you get tax-exempt status back after automatic revocation?

Generally by filing Form 1023 or 1023-EZ with the IRS. Organizations that apply within 15 months of the revocation date and meet eligibility conditions may qualify for streamlined retroactive reinstatement, restoring exempt status back to the original date without a gap ^[8]. Confirm current procedure and fees with the IRS before filing.

Does filing Form 990-N with the IRS also satisfy state requirements?

Not automatically. Form 990-N is a federal filing only. Many states with charitable solicitation registration require a copy of your IRS annual return as part of state renewal, and rules vary widely. Confirm current requirements with your state charity registration office or attorney general's charities bureau.
