TL;DR
Form 990 is the annual information return tax-exempt organizations file with the IRS instead of an income tax return. Small groups under $50,000 in gross receipts file the simple 990-N e-postcard; bigger groups file 990-EZ or full 990. Miss three years in a row and the IRS auto-revokes your exempt status [1].
What is Form 990?
Form 990 is the annual information return that tax-exempt organizations file with the IRS to report money in, money out, and basic governance facts. It is not a tax bill in the normal sense. Most booster clubs, PTOs, and small nonprofits owe nothing with it; the point is transparency, not payment. The IRS calls it a way for exempt organizations to satisfy "annual reporting obligations" so the public and the agency can see how tax-exempt money gets spent [1]. There are several versions depending on your size, and picking the right one is most of the battle for a new treasurer. If your group has 501(c)(3) or 501(c)(4) status (or any other 501(c) subsection), you almost certainly have to file something every year, even if you never applied for exemption formally and just assumed you were covered under a state nonprofit filing. Confirm your exact filing requirement with the IRS and your state charity office, because a few narrow categories (like churches) are excused from filing entirely [2].
What is the 990 tax form used for?
The 990 tax form tells the IRS (and anyone who looks it up on GuideStar or the IRS's own tools) how much your organization brought in, how it spent that money, who runs it, and whether it is still operating within its exempt purpose. Donors, grant makers, and school districts use it to vet a booster club before writing a check. It also functions as the trigger for auto-revocation. The IRS states plainly that organizations required to file an annual return or notice for three consecutive years will automatically lose their tax-exempt status [1]. That's the single scariest fact for volunteer treasurers who inherit a club with no filing history: three missed years and the exemption is gone, not suspended, gone, and you have to reapply from scratch. For background on the exemption itself and how it connects to filing, see form 990.
What is the 990-N e-postcard and who files it?
The 990-N, nicknamed the e-postcard, is the stripped-down version for the smallest organizations. If your booster club or PTO normally has gross receipts of $50,000 or less, you file the 990-N [3]. It takes maybe 10 minutes online, has no attachments, and asks for basics: your EIN, tax year, legal name, address, and a confirmation that gross receipts are still under the threshold. There's no paper option. You file it through the IRS's e-Postcard system, and you need the organization's EIN and login credentials (or you register fresh if this is your first filing) [3]. For a full walkthrough of that specific form, see 990-N and form 990-N.
990-EZ vs 990-N vs full 990: which one do I file?
| 990-N (e-Postcard) | Gross receipts normally $50,000 or less [3] | 10-15 minutes, online only | |
|---|---|---|---|
| 990-EZ | Gross receipts under $200,000 AND total assets under $500,000 [4] | A few hours, needs financial detail | |
| Form 990 (full) | Gross receipts $200,000 or more, or total assets $500,000 or more [4] | Multi-page, often needs a preparer | |
| Form 990-PF | Private foundations, regardless of size | Specialized, rare for booster clubs | Most school booster clubs and PTOs land in the 990-N or 990-EZ range. If you had one blowout fundraising year (a big raffle, a large donor gift) that pushed you over $50,000, you may need to bump up to the 990-EZ for that year, then drop back down. The IRS lets you use the 990-N even in a year you're eligible for a longer form, but not the reverse; if you're over the threshold, you have to file the fuller version [4]. General background lives at [990](/articles/treasurer-basics/990) and 990 tax form. |
Which version you file depends entirely on gross receipts and total assets, not on how your group is organized or what state you're in. Here's the breakdown from IRS instructions [4]: | Filing version | Who files it | Rough filing effort |
When is the 990 due, and what happens if I file late?
Form 990, in any version, is due on the 15th day of the 5th month after your fiscal year ends [5]. If your booster club runs on a calendar year (January to December), that's May 15. If you run on a school-year fiscal calendar (July to June), that's November 15. You can get an automatic 6-month extension by filing Form 8868 before the original deadline [6]. That buys you real breathing room if you're a new treasurer scrambling to reconstruct a checkbook you just inherited. The 990-N itself doesn't have a late penalty attached to a single missed year (there's no dollar penalty for a late e-Postcard specifically), but the 990-EZ and full 990 do carry late-filing penalties, generally running $20 a day up to the lesser of $12,000 or 5% of gross receipts for smaller organizations, with steeper daily penalties for larger ones [7]. The real danger with the 990-N isn't a fine, it's the three-strikes auto-revocation rule that applies across all versions [1].
What happens if my club's tax-exempt status gets auto-revoked?
The IRS publishes an Auto-Revocation List, and once you're on it, your organization is treated as a taxable entity going forward, donations to you are no longer automatically tax-deductible, and you have to reapply for exemption to get back on track [1]. There's no grace period notice before this happens; you find out by checking the list or getting a letter after the fact. The fix is a formal reinstatement filing with the IRS, usually Form 1023 (or 1023-EZ for small organizations) along with a reasonable-cause statement, and depending on how quickly you apply, you may be able to get retroactive reinstatement back to your revocation date . This is genuinely one of the more painful things a new volunteer treasurer walks into: a club that quietly stopped filing three, four, five years ago and nobody noticed because nobody was asking for a tax-deductible receipt. If you're staring at a revoked club right now, don't panic and don't guess. Confirm your status on the IRS Tax Exempt Organization Search tool and talk through your specific reinstatement path with the IRS directly or a qualified preparer; this article isn't a substitute for that.
What is a treasurer? What does a treasurer do?
A treasurer is the person in a club, booster organization, or PTO responsible for the group's money: tracking it, reporting on it, and making sure the organization stays compliant with the IRS and state rules. It's a volunteer role in nearly every booster club and PTO, which is exactly why so many of them run into filing trouble; the person doing the books usually isn't an accountant and often serves one or two years before handing it off. Day to day, what does a treasurer do? The job typically includes: - Keeping the checkbook and bank reconciliations current, monthly at minimum
- Tracking income by source (concessions, raffles, membership dues, sponsorships) and expenses by category
- Preparing a treasurer's report for board or general meetings
- Filing the annual 990 (in whatever version applies)
- Renewing any state charitable registration or raffle license
- Keeping receipts and records organized for the next treasurer or an audit That last point matters more than people expect. A huge share of the mess new treasurers inherit isn't fraud, it's just years of casual handoffs with no paper trail.
What does a treasurer do in a club specifically (vs a company)?
A club treasurer, unlike a corporate one, is usually a volunteer wearing every finance hat at once: bookkeeper, budget planner, tax filer, and internal auditor rolled into one person with no staff underneath them. What does a club treasurer do that a corporate treasurer doesn't? Mostly, everything, because there's no controller or accounting department to hand tasks off to. In a school booster club or PTO, the treasurer role commonly includes: - Managing concession stand or event cash, including deposit procedures
- Reconciling a fundraiser (a car wash, a raffle, a spirit-wear sale) against the deposit slip
- Keeping two sets of eyes on cash whenever possible (one person collects, a different person counts and deposits)
- Reporting to the board in plain language, not accounting jargon
- Making sure the group's EIN, bank account, and 990 filings all match up under the same legal name For the money-handling side specifically, see the financial controls hub for cash-handling and dual-signature guidance, since a good chunk of "treasurer work" is really about controls, not filing paperwork.
What records does a treasurer need before filing the 990?
Before you sit down to file any version of the 990, you need your EIN, your fiscal year dates, total income and expenses for the year broken into rough categories, and a list of major fundraising activities. For the 990-EZ or full 990, you'll also need a breakdown of program service accomplishments, officer names, and (for the full 990) governance policy answers. The IRS 990-N system specifically asks for eight data points: your organization's legal name, EIN, tax year, mailing address, website (if any), confirmation gross receipts are $50,000 or less, and a statement that the organization hasn't terminated [3]. It genuinely is that short. The hard part isn't the form, it's having accurate numbers, especially if the checkbook you inherited doesn't clearly separate fundraiser gross from fundraiser net. One honest tip: reconstruct your gross receipts figure from bank deposits, not from a vague memory of "how the year went." Gross receipts for 990-N purposes means total income before subtracting any costs or expenses, which trips people up constantly [4].
Does a booster club or PTO have to file a 990 even with no formal 501(c)(3) letter?
Generally yes, if your group is organized and operating as a tax-exempt entity (even informally, even without a determination letter), it typically still needs an EIN and typically still needs to file something with the IRS each year, unless it falls under a narrow statutory exception. This is one of the most common gaps for new treasurers: the group has operated for a decade "as a nonprofit" with a bank account and an EIN but never actually applied for or received IRS recognition of exemption, and nobody has filed a 990 the entire time. The safest move is to confirm your organization's exact status with the IRS Tax Exempt Organization Search tool and, if you can't find your group listed, treat that as a red flag requiring a real conversation with the IRS or a qualified nonprofit preparer, not a guess. State rules layer on top of this too; many states require separate charitable registration regardless of your federal status, so also confirm with your state charity office or attorney general's office.
How does the 990 relate to state charity registration and raffle licenses?
The federal 990 and your state's charitable solicitation registration are two separate systems that happen to ask for overlapping information. Filing your 990 doesn't satisfy your state registration requirement, and vice versa; most states with charitable solicitation laws want their own annual renewal, sometimes with a copy of your 990 attached as backup. If your club runs raffles, that's a third, entirely separate layer: state raffle or gaming licenses, usually issued by a state attorney general's charitable gaming division or a state gaming commission, with their own applications, fees, and reporting deadlines. None of this is federal. Confirm both your state charity registration status and any raffle licensing requirement directly with your state charity office or attorney general, since rules and thresholds vary widely and change without much notice.
Where a $99 kit fits into all this
None of the above is complicated once you've done it once. It's confusing the first time because nobody hands new treasurers a checklist when they take over, they just get a shoebox of receipts and a login nobody remembers the password to. BoosterLedger's $99 one-time State-Personalized Treasurer Kit walks through the exact filing version your group likely needs, a state-specific checklist for charity registration and raffle licensing, and a handoff template so the next treasurer isn't starting from zero. It isn't tax or legal advice and it can't guarantee any filing outcome or exemption status; think of it as the organized starting point instead of a blank spreadsheet.
Frequently asked questions
What is a treasurer?
A treasurer is the officer of a club, PTO, or booster organization responsible for tracking money in and out, preparing financial reports, filing required tax returns like the 990, and keeping records for audits or handoffs. In most volunteer groups it's an unpaid, elected position with a one- or two-year term.
What does a treasurer do?
A treasurer reconciles bank statements, tracks income and expenses by category, reports finances to the board, files the annual IRS return (990-N, 990-EZ, or full 990 depending on size), and renews any required state charity or raffle registrations. In small clubs, one person typically does all of this without staff support.
What is Form 990?
Form 990 is the annual information return the IRS requires from most tax-exempt organizations to report income, expenses, and governance details. It replaces a standard income tax return for exempt groups and comes in several versions (990-N, 990-EZ, full 990, 990-PF) depending on gross receipts and assets [1][4].
What is a 990 tax form?
A 990 tax form is the IRS's information return for tax-exempt organizations, not a bill for taxes owed. Most filers, especially small booster clubs and PTOs, report zero tax due; the form exists to disclose finances and confirm the organization is still operating within its exempt purpose.
What is the 990?
"The 990" usually refers to the whole family of IRS annual information returns for tax-exempt organizations: 990-N (under $50,000 gross receipts), 990-EZ (under $200,000 receipts and $500,000 assets), full Form 990 above those thresholds, and 990-PF for private foundations [3][4].
What does a treasurer do in a club?
In a club, the treasurer manages the bank account, tracks fundraiser income and expenses, prepares a treasurer's report for meetings, files the group's annual IRS return, and keeps documentation organized for the next treasurer or an audit. Cash-handling controls (two people counting deposits, for example) usually fall to the treasurer too.
What does a club treasurer do?
A club treasurer handles day-to-day bookkeeping, reconciles fundraiser proceeds against deposits, reports to the board in plain terms, and makes sure the club's 990 filing and any state charity or raffle registration stay current. Unlike a corporate treasurer, they usually do all of this alone as a volunteer.
What does a treasurer of a club do?
The treasurer of a club is responsible for the organization's financial recordkeeping, budget tracking, annual tax filing (Form 990 in whichever version fits the club's size), and handoff documentation for future officers. They're the person a board turns to for "how much money do we actually have."
Do all booster clubs and PTOs have to file a 990?
Most do, if they're organized as tax-exempt entities, even informally without a formal IRS determination letter. A few narrow categories, like certain church-affiliated groups, are excused. Confirm your exact requirement with the IRS and don't assume a lack of a determination letter means no filing is needed.
What is the deadline to file Form 990?
Form 990 (any version) is due the 15th day of the 5th month after your fiscal year ends: May 15 for calendar-year filers [5]. An automatic 6-month extension is available by filing Form 8868 before that deadline [6].
What happens if a booster club doesn't file a 990 for three years?
The IRS automatically revokes tax-exempt status after three consecutive years of failing to file the required annual return or notice [1]. Reinstatement requires a new exemption application (often Form 1023 or 1023-EZ) and, in some cases, a reasonable-cause statement to seek retroactive reinstatement [8].
Which 990 version should a small booster club file?
If gross receipts are normally $50,000 or less, file the 990-N e-Postcard [3]. If receipts are under $200,000 and assets under $500,000, file the 990-EZ. Above either threshold, file the full Form 990 [4]. Check the specific numbers each year since one big fundraiser can push you into a different version.
Does filing the 990 replace state charity registration?
No. The federal 990 and state charitable solicitation registration are separate systems, even though they ask for overlapping financial information. Most states with registration requirements want their own annual renewal, sometimes with a 990 copy attached. Confirm requirements with your state charity office or attorney general.
