TL;DR
The 990-N (e-Postcard) is a free, 8-question online form for tax-exempt organizations with gross receipts normally $50,000 or less. It's due by the 15th day of the 5th month after your fiscal year ends. You file it through the IRS's e-Postcard system at irs.gov, not by mail. Miss it three years running and the IRS automatically revokes your exempt status.
What is the 990-N and who has to file it?
The 990-N, also called the e-Postcard, is the shortest version of the annual information return that tax-exempt organizations file with the IRS. It exists for small nonprofits, the kind of group most booster clubs and PTOs actually are, so they don't have to fill out a full financial statement every year. The IRS says you can file the 990-N if your organization's "annual gross receipts are normally $50,000 or less" [1]. "Normally" matters here. The IRS uses averaging rules for organizations in their first, second, or third year, and a 3-year average for everyone else, so one unusually good fundraising year doesn't automatically bump you up to a longer form. If your receipts run consistently above $50,000, you need Form 990-EZ or Form 990 instead, not the e-Postcard. Form 990 and 990 tax form cover those longer versions. Private foundations can't use the 990-N regardless of size, and some organizations are exempt from filing any 990 series return at all (churches, for instance). If you're not sure which bucket your booster club or PTO falls into, the IRS's own comparison chart for the 990-N and its bigger siblings is the fastest way to check.
What is Form 990, and how is the 990-N different?
| 990-N (e-Postcard) | Gross receipts normally ≤ $50,000 | 8 basic questions online, no financials | |
|---|---|---|---|
| 990-EZ | Gross receipts < $200,000 and total assets < $500,000 | Multi-page return with income/expense detail | |
| Form 990 | Gross receipts ≥ $200,000 or assets ≥ $500,000 | Full return with schedules | If your booster club sits right at the edge, run the 3-year average before you assume you qualify for the e-Postcard. Filing the wrong form isn't the end of the world, but it can mean redoing paperwork later, and if you're already dealing with irs form 990 confusion from a prior treasurer's records, that's the last thing you need. |
Form 990 is the umbrella name for the family of annual information returns tax-exempt organizations file: the full Form 990, the shorter Form 990-EZ, and the 990-N e-Postcard. All three exist to report the same basic thing to the IRS and the public: what money came in, what went out, and whether the organization is still operating within its exempt purpose. The 990-N is the smallest version by far. It's 8 items, all filed online, with no financial detail beyond confirming you're under the $50,000 threshold. Form 990-EZ, by contrast, runs several pages and does require actual income and expense figures. The full Form 990 is longer still and applies to organizations with gross receipts of $200,000 or more or total assets of $500,000 or more [2]. Here's the quick comparison most treasurers actually need: | Form | Who files it | What it requires |
What is the 990 tax form actually used for?
The 990 series exists so the IRS (and the public) can confirm a tax-exempt organization is still doing what it said it would do when it applied for exemption, and that it isn't quietly running like a for-profit business. It's an information return, not a tax bill. Most booster clubs and PTOs owe zero tax with it. That said, filing it isn't optional busywork. The IRS states plainly that "most tax-exempt organizations are required to file an annual return" and that failing to file for three consecutive years results in automatic revocation of exempt status [3]. Once that happens, donations to your group are no longer tax-deductible to the donor, and your organization has to reapply for exemption from scratch, usually with Form 1023 or 1023-EZ and another user fee. So the practical answer to "what is the 990" for a volunteer treasurer is this: it's the annual proof-of-life filing that keeps your tax-exempt status intact. Skip it three years running and you lose the status, more than get a late notice.
How do you file the 990-N (e-Postcard)?
You file the 990-N entirely online through the IRS's e-Postcard system, not by mail and not through the general Form 990 e-file providers used for the longer returns. Go to irs.gov and search "Form 990-N (e-Postcard)" to reach the current filing portal; the process runs through the IRS's e-filing system, and you'll need an active login.gov or ID.me account to access it [1]. You'll need eight things ready before you start: 1. Your organization's EIN (Employer Identification Number) 2. The tax year you're filing for 3. Legal name and mailing address 4. Any other names the organization uses 5. Name and address of a principal officer 6. Your organization's website, if it has one 7. Confirmation that gross receipts are normally $50,000 or less 8. A statement if the organization has terminated or gone out of business That's it. There's no fee. There's no upload of financial statements. Most treasurers can finish it in under 15 minutes once they have the EIN and officer info in hand. One wrinkle worth flagging for a first-time filer: if this is genuinely your organization's first-ever 990-series filing (more than your first time as treasurer), confirm with the IRS that your exemption is actually recognized and active before you file. A booster club that never formally applied for 501(c)(3) or 501(c)(4) status isn't the same as one that has status and just needs its annual e-Postcard.
When is the 990-N due, and what if my fiscal year isn't the calendar year?
The 990-N is due by the 15th day of the 5th month after your organization's accounting period ends [1]. For a booster club running on a calendar year (January through December), that means the filing is due May 15 of the following year. For groups on a school-year fiscal calendar, say July 1 to June 30, the deadline lands November 15. There's no extension available for the 990-N specifically, though the IRS notes you can still file late; there's no late-filing penalty on the e-Postcard itself the way there is for the longer 990 and 990-EZ. The real risk isn't a fine, it's the three-strikes revocation rule described above. File a year late, no problem, no penalty. Miss three years straight, and status is gone automatically, no warning letter required. If you don't know your organization's exact fiscal year end, check your original exemption application or a prior year's filing. It's easy to assume calendar year when the group has actually always operated on a school-year cycle, and that mismatch alone causes a lot of "why did we get flagged" confusion.
What does a treasurer do, exactly?
A treasurer's core job is keeping the organization's money honest and legal: tracking what comes in, what goes out, and making sure the paperwork that keeps the group's nonprofit status intact actually gets filed. For a booster club or PTO, that usually breaks down into four buckets: bookkeeping, banking, filings, and reporting to the board or membership. Day to day, that means reconciling the bank account, depositing fundraiser cash promptly instead of letting it sit in someone's car, tracking which checks have cleared, and keeping receipts organized so next year's treasurer (or an auditor, or the IRS) can follow the trail. Annually, it means the 990-N or whichever 990 variant applies, plus any state charity registration renewal your state requires. Financial controls around cash handling matter here as much as the filing itself; a clean 990-N doesn't help if the underlying books are a mess. What a treasurer does NOT do, at least not alone, is make spending decisions unilaterally. Good practice, and often the bylaws, require two signers on checks above a threshold and board approval for anything beyond routine expenses.
What does a club treasurer do differently from a corporate one?
A club or booster treasurer handles the same core functions as any treasurer, tracking money, filing what's required, reporting to the group, but usually with far less infrastructure. No paid bookkeeper, no accounting software subscription, often no accountant on call. It's one volunteer, a shared spreadsheet or a $12/month accounting app, and a shoebox of receipts from the last concession stand shift. That changes what "what does a treasurer do in a club" looks like in practice. A corporate treasurer worries about cash flow forecasting and debt covenants. A booster club treasurer worries about whether the uniform fundraiser deposit matches the tally sheet, whether the raffle license got renewed, and whether last year's treasurer left behind login credentials for the bank account. The stakes are still real, just smaller in scale and higher in personal exposure. A corporate treasurer has a legal and compliance department behind them. A volunteer treasurer often has nobody, which is exactly why keeping the 990-N filing on a calendar (with a reminder set for 60 days before the deadline, not the deadline itself) matters so much. Treasurer basics is the place to start if you're building that structure from zero.
What happens if a booster club or PTO misses the 990-N deadline?
Missing one year's 990-N deadline causes no direct penalty. The IRS doesn't fine small organizations for a single late e-Postcard the way it does for a late Form 990 or 990-EZ. But the clock doesn't reset either, and the IRS's rule is unambiguous: organizations that fail to file for three consecutive years automatically lose their tax-exempt status under the law governing automatic revocation [3]. That three-year window applies per organization, tracked by EIN, regardless of how many treasurers cycled through in that time. This is the single biggest reason booster clubs lose exempt status: not fraud, not mismanagement, just three consecutive years of nobody filing because the person who knew how to do it quit and nobody handed off the login. You can check whether your organization's status is currently at risk or already revoked using the IRS Tax Exempt Organization Search tool [4]. If revocation already happened, reinstatement isn't automatic. You typically need to reapply using Form 1023 or Form 1023-EZ and pay the associated user fee again, and depending on timing you may be able to request retroactive reinstatement under the procedures in Revenue Procedure 2014-11 [5]. Confirm the exact reinstatement path with the IRS, since the rules around retroactivity have specific timing windows.
How do you check if your organization's exempt status was already revoked?
Use the IRS Tax Exempt Organization Search (TEOS) tool at irs.gov. It lets you search by organization name or EIN and shows current exempt status, along with a separate list of organizations that have had their status automatically revoked for failing to file [4]. Run this search the moment you take over as treasurer, before you assume the prior person kept everything current. It costs nothing and takes two minutes, and it's the single fastest way to find out whether you're inheriting a clean filing history or a revocation problem that predates you. If the search shows revocation, don't panic, but don't ignore it either. Note the revocation date, gather whatever old 990-N confirmations or filing records exist, and plan for a reinstatement application rather than assuming next year's e-Postcard will fix things retroactively. It won't. Once status is revoked, you're back to applying for exemption, more than filing an annual return.
Does filing the 990-N also cover state requirements?
No. The 990-N is a federal filing with the IRS only. Most states have entirely separate requirements for charitable organizations, commonly a charity registration or renewal filed with the state Attorney General's office or a Secretary of State charities division, and these run on their own schedule with their own thresholds. Some states also require a copy of your federal 990 (whichever version you filed) as part of that state registration. Others don't. This varies enough by state that there's no single correct answer here: confirm with your state charity office or attorney general what your specific state requires, since a booster club in one state might have zero state-level filing obligation while a nearly identical group one state over owes an annual charitable solicitation registration with its own fee and deadline. Don't assume the IRS e-Postcard is a one-stop filing. Treat it as one piece of a two-part (sometimes three-part, if your state also requires a raffle license renewal) annual compliance checklist.
What records should you keep after filing the 990-N?
Keep a copy of the confirmation the IRS system generates once your 990-N submits successfully. The e-Postcard system doesn't mail you anything, so that confirmation screen or emailed receipt is your only proof of filing; screenshot it or save the PDF the same day you file. Beyond the filing confirmation itself, keep the underlying numbers you used to confirm you qualified for the 990-N in the first place: your gross receipts for the year and the prior two years, since that's what the $50,000 average threshold is based on. If your organization ever gets close to that line, this record is what lets next year's treasurer (or you, a year from now) confirm which form applies without redoing the math from scratch. A simple year-by-year folder works fine: one file per fiscal year with the EIN, the filing confirmation, the gross receipts figure, and the officer info used at the time. That folder is also exactly what a new treasurer needs during handoff, so it's worth building even if you never expect to hand the job off soon. This is the kind of setup a State-Personalized Treasurer Kit is built for: a $99 one-time packet with your state's specific filing calendar and a template for exactly this kind of year-over-year record, so you're not reconstructing it from memory during a rushed handoff.
What is a treasurer, in plain terms, before you even get to the IRS?
Strip away the filings and forms, and a treasurer is the person accountable for an organization's money: what it has, where it came from, where it went, and whether that's documented well enough that someone else could verify it. Everything else, the 990-N, the bank reconciliations, the raffle license, the cash-count sheets, flows from that one core job. For a booster club or PTO specifically, that accountability usually sits with one volunteer and a bank account, sometimes with a co-signer, sometimes with none. The role carries real legal weight even at that small scale. Officers and directors of a nonprofit, including the treasurer, generally owe the organization a duty of care, meaning reasonable diligence in handling its affairs, which is a big part of why sloppy books or missed filings aren't just annoying, they're a real compliance and, in rare cases, personal liability exposure. The good news: the actual mechanics for a small booster club or PTO are genuinely manageable. A clean checking account, a simple ledger, an annual 990-N filing on a calendar reminder, and a state registration check once a year cover most of what the role requires. It's not glamorous work, but it's learnable in an afternoon, not a semester.
Frequently asked questions
What is a 990-N and do I have to file one?
The 990-N (e-Postcard) is a short, free, online filing for tax-exempt organizations with gross receipts normally $50,000 or less. If your booster club or PTO fits that threshold and isn't a private foundation, you likely file it. Check IRS.gov's 990-N page to confirm your organization qualifies before assuming.
What is Form 990 and how does it relate to the 990-N?
Form 990 is the umbrella name for the annual information return family: the full Form 990, Form 990-EZ, and the 990-N e-Postcard. Which version you file depends on gross receipts and assets. Under $50,000 in gross receipts, the 990-N usually applies; above that, 990-EZ or full 990 kicks in.
What does a treasurer do for a booster club or PTO?
A treasurer tracks incoming and outgoing money, reconciles the bank account, keeps receipts and records organized, and handles annual filings like the 990-N and any state charity registration. The role also usually includes reporting a financial summary to the board or membership at meetings.
What is a 990 tax form used for?
It's an annual information return, not a tax bill for most small nonprofits. The IRS uses it to confirm a tax-exempt organization is still operating within its exempt purpose. Filing it, in whatever version applies, is also what keeps your tax-exempt status from being automatically revoked.
How much does it cost to file the 990-N?
Nothing. The 990-N e-Postcard has no filing fee. It's an 8-question online form through the IRS's e-filing system, no financial statements or attachments required. The only real cost is your time, usually under 15 minutes once you have your EIN and officer info ready.
When is the 990-N due each year?
By the 15th day of the 5th month after your organization's fiscal year ends. Calendar-year organizations (January to December) file by May 15. School-year organizations (July to June) file by November 15. There's no extension option specific to the 990-N.
What happens if my booster club never filed a 990-N before?
First confirm the organization actually has recognized tax-exempt status with the IRS; the 990-N assumes exemption already exists. If status is confirmed and active, just file the current year's 990-N going forward and don't worry about back-filing years that predate your knowledge, unless the IRS specifically flags a gap.
Can I switch from 990-EZ to 990-N if my receipts drop?
Yes, if your gross receipts genuinely fall to $50,000 or less on the IRS's averaging basis (current year plus prior two years), you can file the 990-N instead of the 990-EZ that year. Confirm the average calculation carefully rather than judging off one good or bad year alone.
What is the penalty for filing the 990-N late?
There's no direct monetary penalty for a single late 990-N. The real risk is cumulative: fail to file for three consecutive years and the IRS automatically revokes tax-exempt status, no warning letter required. One late year, by itself, causes no formal penalty.
How do I know if my organization's tax-exempt status was already revoked?
Search the IRS Tax Exempt Organization Search (TEOS) tool at irs.gov by your organization's name or EIN. It shows current status and includes a separate published list of organizations automatically revoked for failing to file three years running.
Does the 990-N replace state charity registration requirements?
No. The 990-N is a federal IRS filing only. Most states have separate charity registration or renewal requirements handled by the state Attorney General or Secretary of State charities office, on a different schedule with different thresholds. Confirm your specific state's requirement separately.
What does a club treasurer do differently from a company treasurer?
The core job is similar, tracking money and filing required paperwork, but a club treasurer usually works alone, without paid staff or dedicated software, handling everything from concession-stand cash counts to the annual IRS filing personally, often on a volunteer basis with no formal accounting background required.
What records do I need before I can file the 990-N?
You need your organization's EIN, the tax year, legal name and mailing address, any alternate names used, a principal officer's name and address, the website if one exists, and confirmation gross receipts are normally $50,000 or less. That's the full list; no financial statements required.
