IRS Form 990-N explained: who files, deadline, and how

Last updated 2026-07-24

What is the 990-N (e-Postcard) and who has to file it?

Form 990-N is the shortest, simplest version of the annual information return that most tax-exempt nonprofits owe the IRS every year. The IRS calls it the "e-Postcard" because that's basically what it is: a short online form, not a tax return with schedules and financial statements attached. You can file it if your organization's gross receipts are normally $50,000 or less. The IRS defines "normally" using a rolling average over one, two, or three years depending on how long you've been around, so a single unusually big fundraiser year doesn't automatically bump you up. Booster clubs, PTOs, small youth sports leagues, alumni groups, and similar volunteer-run groups are the classic 990-N filers. If your gross receipts run higher than that, you'll file Form 990-EZ or the full Form 990 instead, both of which ask for actual financial detail. The 990 tax form family scales with your organization's size, and 990-N is the version built for the smallest ones. One thing that trips up new treasurers: filing 990-N is mandatory, not optional, even though it's free and takes ten minutes. "Most small tax-exempt organizations whose annual gross receipts are normally $50,000 or less" are required to file it annually, per the IRS ^[1]. Skipping it because your group is small and volunteer-run is exactly how organizations end up on the auto-revocation list.

What is Form 990 (the bigger picture)?

Form 990 is the IRS's annual information return for tax-exempt organizations, the mechanism by which the IRS (and the public) can see what a nonprofit took in, spent, and paid its people. It's not a corporate tax return in the traditional sense, because most exempt organizations don't owe federal income tax on program-related income. Instead it's a disclosure document. There are four versions in practice: the full Form 990 for larger organizations, Form 990-EZ for mid-size ones, Form 990-PF for private foundations, and Form 990-N for the smallest. Which one you file depends entirely on gross receipts and total assets, not on how the organization is structured or what state it's in. The IRS publishes the exact thresholds, and they matter because filing the wrong version, or filing 990-N when you actually crossed the $50,000 threshold, can create problems down the line. Organizations with gross receipts under $200,000 and total assets under $500,000 can generally choose 990-EZ over the full 990, but 990-N is only available under the $50,000 gross receipts test.

What information does the 990-N actually ask for?

The e-Postcard is short by design. The IRS lists eight items you need to submit ^[1]: Employer Identification Number (EIN), tax year, legal name and mailing address, any other names the organization uses, name and address of a principal officer, website address if the organization has one, confirmation that annual gross receipts are normally $50,000 or less, and a statement if the organization has terminated or is terminating. That's it. There's no balance sheet, no program expense breakdown, no list of donors. This is intentional: the e-Postcard exists so tiny nonprofits don't need an accountant or a nonprofit tax specialist just to stay compliant. You file it electronically through the IRS's own e-Postcard system, and there's no paper alternative and no fee ^[1].

When is the 990-N deadline?

December 31	May 15
June 30	November 15
September 30	February 15

Form 990-N is due by the 15th day of the 5th month after the end of your organization's fiscal year ^[1]. For a nonprofit on a calendar fiscal year (ending December 31), that means the filing is due May 15 of the following year. If your booster club or PTO runs on a school-year fiscal calendar (say, July 1 to June 30), your 990-N would be due November 15. Check your organizing documents or ask whoever set up your EIN what fiscal year the IRS has on file, because plenty of groups assume calendar year when they're actually not. There's no extension form for 990-N specifically, unlike 990 and 990-EZ. If you miss the date, you just file it late; there's no penalty for a single late e-Postcard, but there's a serious consequence for missing it repeatedly (more on that below). | Fiscal year end | 990-N due date |

What happens if you miss the 990-N deadline, or miss it three years running?

One missed year, on its own, doesn't cost you anything. There's no monetary penalty for filing 990-N late. That's part of why so many volunteer treasurers let it slide, especially during a leadership handoff when nobody's sure who filed last. The real danger is the three-year rule. Section 6033(j) of the Internal Revenue Code requires automatic revocation of tax-exempt status for any organization that fails to file its required return (990, 990-EZ, or 990-N) for three consecutive years ^[2]. The IRS states plainly: "Organizations that do not file for three consecutive years automatically lose their tax-exempt status" ^[2]. This isn't a warning letter situation you can argue your way out of. It's automatic, and it happens on the filing deadline of the third missed year, not on some later notice date. Plenty of booster clubs and PTOs discover the loss only when a bank or grant funder asks for proof of exempt status and the group isn't on the IRS's list anymore. Once revoked, the organization is treated as a taxable entity going forward, and its name shows up on the IRS Tax Exempt Organization Search auto-revocation list ^[3]. Getting reinstated means filing Form 1023 (or 1023-EZ if eligible) again, along with the fee, even though you were exempt before. This is the scenario that causes the most panic for a new treasurer walking into an inherited mess, and it's exactly why checking your filing history should be step one on any handoff, something we cover in more detail on our handoff-and-audits pages.

How do you check whether your organization is up to date, or already revoked?

Start with the IRS Tax Exempt Organization Search tool, which lets you look up an organization by name or EIN and see its filing history and current exemption status ^[3]. This is free, public, and the fastest way to confirm where you actually stand instead of guessing based on what the last treasurer said. If your organization shows up on the Auto-Revocation List, don't panic, but don't ignore it either. You'll need to file Form 1023 or 1023-EZ to apply for reinstatement, and depending on how quickly you apply, the IRS may reinstate your exemption retroactively to the date of revocation ^[2]. There are specific procedures (Rev. Proc. 2014-11) for streamlined retroactive reinstatement if you apply within 15 months of revocation or of the notice, and different rules if you're outside that window ^[4]. If you're not sure which form applies to your organization's size and history, that's the point to confirm with the IRS and, if your state requires separate charity registration, with your state charity office or attorney general as well, since state-level nonprofit and charitable solicitation status is a separate track from federal tax exemption.

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

A treasurer is the person in a club, booster organization, or PTO responsible for tracking the money: what comes in, what goes out, and whether the numbers add up at the end of the year. It's a volunteer role in the vast majority of youth-sports and school-affiliated groups, not a paid position, and it usually rotates every one to three years. What does a treasurer do in practice? The job generally covers: keeping a checkbook or accounting software current, depositing and documenting cash from fundraisers and concessions, paying vendors and reimbursing volunteers, reporting a budget-to-actual summary at meetings, and making sure required filings (990-N being the big one for small groups) get done on time. What does a club treasurer do that's different from a corporate bookkeeper? Mostly scale and simplicity. A booster club treasurer isn't running payroll or managing investment accounts (usually), but they are the sole line of defense against sloppy cash handling, which is why financial-controls basics like two-signature requirements and dual counting of concession cash matter even for a group with a $15,000 annual budget. What does a treasurer of a club do when nobody trained them? Honestly, a lot of learning by digging through the last treasurer's shoebox of receipts and calling the bank to ask what's on the account. That's the reality for a huge share of new booster and PTO treasurers, and it's the reason organized handoff checklists and starter kits exist at all.

Does a small booster club or PTO really need to file anything with the IRS?

Yes, almost always, if the organization has its own EIN and is recognized (or operating) as tax-exempt. The $50,000 gross receipts threshold for 990-N is a filing simplicity threshold, not an exemption from filing entirely. Every organization recognized under section 501(c) is required to file something annually unless it falls into a narrow set of exceptions (certain church-related organizations, for instance) ^[1]. A lot of booster clubs get this wrong in a specific way: they're organized as a nonprofit corporation with their state, have an EIN, run a bank account under the club's name, but never actually applied for federal tax-exempt recognition (Form 1023 or 1023-EZ), and therefore aren't in the IRS system as an exempt organization at all. In that case, there's no 990-N obligation yet because there's no exempt status to maintain, but there may be state-level obligations, and any donations the group solicits as tax-deductible are legally questionable. If you're not sure whether your organization has a determination letter on file, the ^[990](/articles/treasurer-basics/990) overview page walks through how to check, and the IRS's own Tax Exempt Organization Search ^[3] is the definitive source.

990-N vs 990-EZ vs full 990: which one do you actually file?

Form	Gross receipts	Total assets	Complexity
990-N (e-Postcard)	Normally $50,000 or less	No asset test	8 data points, online only
990-EZ	Under $200,000	Under $500,000	Multi-page, financial summary
Full 990	$200,000 or more, or assets $500,000+	Any	Full financial statements, schedules
990-PF	Private foundations, any receipts	Any	Full financial detail, required regardless of size	These thresholds come directly from IRS guidance on annual exempt organization returns. Note that an organization under the 990-N threshold can still choose to file the 990-EZ instead if it wants to (some do, for grant applications that ask for a filed 990 rather than an e-Postcard), but it can't go the other direction: you can't file 990-N if your gross receipts genuinely exceed $50,000 for the relevant averaging period. If your booster club had one blowout fundraising year, say a $60,000 gala, don't assume you're automatically bumped to 990-EZ forever. The IRS's averaging rule looks at gross receipts across up to three years, so check the specific formula in the instructions for form-990-n before deciding which form applies.

Where do you actually file the 990-N?

You file Form 990-N through the IRS's online e-Postcard filing system, accessible from the IRS's Tax Exempt Organizations page ^[1]. There's no paper version. You'll need to create or use an IRS.gov account, have your organization's EIN handy, and confirm the eight data points listed above. The process itself takes most treasurers under fifteen minutes once they have the EIN and a principal officer's name and address ready. There's no login fee, no filing fee, and you get an immediate confirmation (accepted or rejected) rather than waiting weeks. If the system rejects your submission, it's almost always because the EIN doesn't match IRS records exactly, which is usually a sign the organization's registration details are outdated somewhere. A lot of new treasurers wonder if they need an accountant for this step. You don't, for the 990-N specifically, precisely because it's a checkbox-style disclosure, not a financial return. If your organization is required to file 990-EZ or the full 990 instead, that's a different conversation, and getting a CPA or an experienced nonprofit bookkeeper involved is reasonable at that point.

What should a new treasurer do in the first month on the job?

Pull the organization's filing history from the IRS Tax Exempt Organization Search tool first, before anything else ^[3]. This tells you immediately whether you're current, behind, or already revoked, and it's free. Second, find the EIN, the last filed 990-N confirmation (if any), and the organization's fiscal year end. If nobody can produce these, that's the first red flag in a handoff, and it's worth reading through general handoff-and-audits guidance on what a clean transition packet should include. Third, mark the actual due date on a calendar with a 60-day-ahead reminder, not the exact deadline, since volunteer treasurers get busy and miss same-day deadlines constantly. Fourth, check whether your state also requires a separate charitable registration or annual report; federal 990-N filing and state charity registration are two completely different systems, and being current on one says nothing about the other. Confirm the specific requirement with your state charity office or attorney general, since these vary widely and change periodically. We built a $99 one-time State-Personalized Treasurer Kit specifically for this first-month scramble: it maps out your state's specific raffle, registration, and filing requirements alongside the federal 990-N basics, so you're not piecing this together from a dozen government PDFs on your first weekend in the job.

Frequently asked questions

What is a treasurer?

A treasurer is the person responsible for an organization's money: tracking income and expenses, keeping bank records straight, paying bills, and handling required filings like the IRS Form 990-N. In booster clubs, PTOs, and youth sports leagues, it's almost always a volunteer role that rotates every one to three years.

What does a treasurer do day to day?

Day to day, a treasurer records deposits and expenses, reconciles the bank statement monthly, keeps receipts for reimbursements, and prepares a budget update for board meetings. Annually, they handle the required IRS filing (often Form 990-N) and any state charity registration renewal, and they hand off clean records to the next treasurer.

What is Form 990?

Form 990 is the IRS's annual information return for tax-exempt organizations, showing income, spending, and governance details to the IRS and the public. It comes in several versions (990-N, 990-EZ, full 990, 990-PF) depending on the organization's gross receipts and assets, with 990-N being the simplest version for organizations under $50,000 in gross receipts.

What is the 990-N e-Postcard exactly?

The 990-N, or e-Postcard, is a short online filing for tax-exempt organizations with gross receipts normally $50,000 or less. It asks for about eight basic facts (EIN, tax year, address, principal officer, website) and is filed for free through the IRS's website, with no financial detail required.

Who is required to file Form 990-N?

Tax-exempt organizations recognized under section 501(c) whose gross receipts are normally $50,000 or less are required to file 990-N annually, unless they choose to file 990-EZ instead. Most small booster clubs, PTOs, and volunteer youth sports groups fall into this category. Check with the IRS if you're unsure which threshold applies to your group.

What happens if a nonprofit doesn't file 990-N for three years?

The IRS automatically revokes tax-exempt status under Internal Revenue Code section 6033(j) if an organization fails to file its required return for three consecutive years. There's no warning notice required before revocation happens; it's automatic on the filing deadline of the third missed year.

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, which shows current status and whether the group appears on the Auto-Revocation List. This is free and public, and it's the fastest way to confirm your status instead of relying on secondhand information from a past treasurer.

Is there a penalty for filing 990-N late?

No monetary penalty applies to a single late 990-N filing. The real risk is cumulative: miss it three years in a row and the IRS automatically revokes tax-exempt status, which is a much bigger problem than any late fee would have been.

What's the difference between 990-N and 990-EZ?

990-N is for organizations with gross receipts normally $50,000 or less and asks for eight basic data points online. 990-EZ is for organizations with gross receipts under $200,000 and total assets under $500,000, and it requires an actual financial summary with multiple schedules, more than a checkbox form.

What does a club treasurer do that a regular bookkeeper doesn't?

A club treasurer usually handles cash-heavy fundraising events (concessions, raffles, car washes) directly, in addition to standard bookkeeping tasks. They're also typically the person responsible for the organization's tax-exempt compliance, including annual IRS filings and state charitable registration, which a corporate bookkeeper wouldn't normally touch.

Can a small booster club file 990-N if it had one unusually large fundraising year?

Possibly still yes. The IRS uses an averaging formula over one, two, or three years to determine if gross receipts are "normally" $50,000 or less, so a single big year doesn't automatically disqualify you from 990-N. Check the specific averaging rule in the IRS instructions to confirm your situation.

Do I need an accountant to file Form 990-N?

Most treasurers don't need one for 990-N specifically, since it only asks for basic identifying information and takes about fifteen minutes online. If your organization actually needs to file 990-EZ or the full Form 990 instead, involving a CPA or experienced nonprofit bookkeeper is a reasonable and often worthwhile expense.

How do I reinstate tax-exempt status after automatic revocation?

You file Form 1023 or Form 1023-EZ again, along with the applicable fee, to apply for reinstatement. If you apply within 15 months of revocation, streamlined procedures under Rev. Proc. 2014-11 may allow retroactive reinstatement back to the revocation date; outside that window, different rules apply. Confirm current procedures directly with the IRS.
