TL;DR
Form 990 is the annual information return that tax-exempt organizations file with the IRS to report income, spending, and activities. Most small booster clubs and PTOs with gross receipts under $50,000 file the simplest version, Form 990-N, an 8-question online form. Miss it three years running and the IRS automatically revokes your tax-exempt status.
What is Form 990?
Form 990 is the annual information return that most tax-exempt organizations have to file with the IRS. It is not an income tax return in the way a business files one, because tax-exempt groups generally don't owe income tax. Instead, it's a disclosure form. It tells the IRS, and anyone else who looks it up, how much money came in, where it went, who runs the group, and whether it's still operating the way it claimed when it applied for exemption. The IRS describes the return family this way on its own site: organizations use the Form 990-series returns to "report the information required by section 6033" of the Internal Revenue Code [1]. Section 6033 is the actual law that requires most exempt organizations to file annually. If you're a treasurer wondering why this thing even exists, that's the short answer: Congress requires it, and the IRS built the form to collect it. There isn't one single "990." There's a family of versions sized to the organization, and picking the wrong one (or filing none at all) is the single most common mistake new booster club and PTO treasurers make. We cover the version-by-version breakdown later in this piece, and you can also check the form 990 overview for a side-by-side comparison.
What does a treasurer do?
A treasurer is the person responsible for the money: tracking it, reporting it, and making sure the group's spending matches what the board or members approved. In a small nonprofit like a booster club, PTO, or youth sports league, the treasurer is usually the only person who touches the bank account regularly, which means the job carries more weight than the title suggests. Day to day, that means recording deposits and expenses, reconciling the bank statement every month, paying vendors, collecting dues or fundraising proceeds, and keeping receipts organized enough that someone else could reconstruct the year if you got hit by a bus. Annually, it means preparing (or arranging) the Form 990 filing, giving the board a financial report, and helping with any state charity registration renewal. Nobody hands new treasurers a manual for this. Most people learn it by inheriting a shoebox of receipts from the last treasurer and figuring it out as deadlines hit. That's exactly the gap a [990](https://boosterledger.com/articles/irs-and-990/990) filing checklist or a state-specific kit is meant to close, but even without one, the core job doesn't change: know what's in the account, know where it came from, and be able to show it.
What is a treasurer, exactly, and what do treasurers do in a club?
A club treasurer is the officer (elected or appointed) who has legal and practical responsibility for the organization's finances. "Treasurer of a club" isn't a ceremonial title. In most bylaws, the treasurer has actual signing authority on the bank account and actual liability if money goes missing on their watch. What does a treasurer do in a club, specifically? A few concrete things every month or season: - Deposit fundraising and dues income promptly, with a written count sheet signed by two people.
- Track every expense against a budget the board approved, more than against "what's in the account."
- Reconcile the bank statement against the check register or bookkeeping software.
- Report a simple income-and-expense summary at every board meeting.
- Keep receipts and bank statements for at least the IRS-recommended retention period (generally three years from filing, longer for employment tax records) [2]. What a treasurer does not do, at least not alone, is decide how to spend money. That's a board decision. The treasurer's job is to make sure the books reflect what the board decided, and that the group stays compliant with the IRS and state filing requirements tied to its tax-exempt status.
Who has to file Form 990?
Almost every organization recognized as tax-exempt under Internal Revenue Code section 501(c) has to file some version of the 990, every year, based on gross receipts and assets. The IRS states plainly: "Most tax-exempt organizations are required to file an annual return" [1]. There are a few carve-outs. Churches and certain church-affiliated organizations are generally exempt from the filing requirement [3]. State institutions and a few other narrow categories also get exceptions. But a typical booster club, parent-teacher organization, or youth sports league that has 501(c)(3) or 501(c)(4) status does not get a pass just because it's small or all-volunteer. Gross receipts of $500 for the year still trigger a filing obligation, just the easiest one (the 990-N). A lot of booster club boards assume that because they never applied for exemption, or because nobody remembers doing the paperwork, they don't have to file anything. That assumption is exactly how organizations end up on the IRS auto-revocation list. If your group has an EIN and has ever represented itself as tax-exempt, or its parent organization got it exemption years ago and nobody since has kept up the filings, check your status with the IRS Tax Exempt Organization Search before assuming you're in the clear [4].
Which version of Form 990 does my group need?
| Normally $50,000 or less | any | Form 990-N (e-Postcard) | |
|---|---|---|---|
| Less than $200,000 | Less than $500,000 | Form 990-EZ (or full 990) | |
| $200,000 or more | $500,000 or more | Form 990 (full) | |
| Private foundations | any | Form 990-PF | Most booster clubs, PTOs, and youth sports leagues with a single team or a modest annual fundraiser fall into the first row. If your group's average gross receipts over the last three years are $50,000 or under, you almost certainly qualify for the 990-N, also called the e-Postcard, which is an 8-question online form with no financial detail required beyond confirming you're under the threshold [6]. If a big fundraiser or a one-time grant pushes you over $50,000 in a given year, you may need to step up to the 990-EZ for that year, which does require a real income statement and balance sheet. Groups that size still rarely need the full 990, which is built for organizations with $200,000+ in receipts or $500,000+ in assets, but check your specific year's numbers with the IRS instructions rather than assuming last year's form still fits. |
The version depends almost entirely on gross receipts and total assets for the year. Here's the breakdown the IRS uses [5]: | Gross receipts | Total assets | Which form |
What is Form 990-N (the e-Postcard) and how is it different?
Form 990-N is the simplest version, built specifically for small tax-exempt organizations. The IRS describes it as an "annual electronic notice" for organizations whose gross receipts are normally $50,000 or less [6]. It has to be filed electronically, there is no paper option, and there's no fee to file it. The form asks for eight things: the organization's legal name and any doing-business-as name, EIN, mailing address, tax year, confirmation gross receipts are $50,000 or less, and confirmation the organization hasn't terminated. That's it. No income statement. No expense breakdown. It takes most treasurers under 15 minutes once they have the EIN and prior-year filing info in hand. The catch is that ease makes it easy to forget. Because there's no dollar amount involved and no financial reporting stress, treasurers assume it's optional or that "someone else" is filing it. It isn't optional, and if your organization's total gross receipts (more than what a specific committee handled, the whole legal entity) top the threshold in a given year, you need the 990-EZ or full 990 instead, not the e-Postcard.
What happens if a booster club or PTO doesn't file Form 990?
Miss the filing for three consecutive years and the organization automatically loses its tax-exempt status. This is not a warning-letter, second-chance situation. The IRS states it directly: "Organizations that fail to file for three consecutive years automatically lose their tax-exempt status" and this revocation is required by law, not IRS discretion . It applies even to organizations that were never required to file anything but the 990-N. Once revoked, the organization owes income tax on its revenue going forward as if it were a regular taxable entity, and donors can no longer deduct contributions to it. For a booster club running concession stands and car washes, that mostly means annoyance and paperwork. For a PTO holding grants or larger corporate sponsorships, it can mean real tax liability. The fix, if you're already revoked, is reinstatement through IRS Revenue Procedure 2014-11, which lays out streamlined retroactive reinstatement for small organizations that qualify . It generally requires filing the 990-N (or 990-EZ) forms for the years you missed, submitting a reinstatement application, and paying the applicable user fee. Confirm current fee amounts and forms with the IRS before you start, because these details get updated periodically.
When is Form 990 due?
Form 990 (any version) is due on the 15th day of the 5th month after your organization's accounting period ends. For a group on a calendar year (January to December), that's May 15 . For a group on a July-to-June fiscal year, which is common for school-affiliated boosters and PTOs, the deadline is November 15. You can request a single automatic extension of up to six months by filing Form 8868 before the original deadline . That moves a May 15 deadline to November 15. There's no extension available for the 990-N itself in the traditional sense (it's so simple the IRS doesn't require one), but late filing of the 990-N still counts against your three-year revocation clock. Don't treat it as low priority just because there's no financial penalty attached the way there is for 990-EZ and full 990 late fees.
Are there penalties for filing Form 990 late?
Yes, for the 990-EZ and full Form 990, though not for the 990-N directly (the risk there is revocation, covered above, not a dollar penalty). For 2024, the IRS penalty for a late Form 990 or 990-EZ is generally $25 per day the return is late, up to a maximum of the lesser of $12,500 or 5% of the organization's gross receipts for the year, for smaller organizations . Larger organizations face steeper daily penalties and caps. These numbers get adjusted, so confirm the current-year figures on the IRS penalty page before assuming an exact dollar amount applies to your filing. The practical takeaway for a volunteer treasurer: the penalty structure rewards filing something, even late, over filing nothing. A late 990-EZ costs money. Three years of silence costs your tax-exempt status entirely, which usually costs far more in accountant and reinstatement fees to fix than any late penalty would have.
Is Form 990 public? Can anyone see it?
Yes. Form 990 filings (other versions besides the 990-N) are public records, and the IRS and most nonprofit databases publish them. Donors, parents, board candidates, and reporters can and do look up a group's 990 to see salaries, program spending, and total assets. The IRS's own Tax Exempt Organization Search tool lets anyone pull filed 990s and check whether an organization's exempt status is current [4]. This matters for booster clubs and PTOs more than treasurers usually expect. A parent deciding whether to trust the group with a $200 fundraising check, or a school district reviewing an affiliated booster club's finances before a partnership renewal, can and sometimes does pull the 990. Sloppy or missing filings are visible to anyone who looks. That's a real (if underappreciated) reason to keep filings current beyond just avoiding IRS penalties.
How does Form 990 relate to state charity registration?
Filing Form 990 with the IRS is a federal requirement. It doesn't automatically satisfy your state's separate charitable solicitation registration, if your state has one. Many states require nonprofits that solicit donations, run raffles, or hold fundraisers to register with a state charity official (often the attorney general's office or secretary of state), and some states will actually ask for a copy of your 990 as part of that registration or its annual renewal. California's Registry of Charitable Trusts, for example, requires most charitable corporations to file Form RRF-1 annually alongside a copy of the IRS return . The rules vary a lot by state and change periodically, so confirm the current requirement with your state charity office or attorney general before assuming your IRS filing is the only paperwork you owe. A booster club running a raffle or a large fall fundraiser especially needs to check both boxes: federal 990 compliance and state charitable registration, since raffle licensing often depends on the group's registered nonprofit status being current.
Do all-volunteer PTOs and booster clubs really need to file?
Yes. If the organization has 501(c) tax-exempt status (or has ever applied for or claimed it), size and volunteer status don't exempt you from filing. The IRS threshold for the simplest form, the 990-N, kicks in at gross receipts normally $50,000 or less [6], which describes the overwhelming majority of single-team booster clubs and school PTOs. That means most of these groups file the easiest version, not that they skip filing. Where groups genuinely get confused is when a booster club was formed informally years ago, maybe with an EIN obtained for a bank account, but never actually filed a 501(c)(3) exemption application (Form 1023 or 1023-EZ). If that's your situation, you may not be a tax-exempt organization at all in the IRS's eyes, which changes the whole conversation, from "which 990 do I file" to "do we need to apply for exemption in the first place." Pull your organization's record on the IRS Tax Exempt Organization Search [4] to see if you're even listed before assuming a 990-N is the fix you need.
What should a new treasurer do first?
Start by finding out whether your organization currently has tax-exempt status and whether its filings are current. Search the group's name and EIN on the IRS Tax Exempt Organization Search [4]. If it shows up with active status and recent 990-N or 990-EZ filings, you're inheriting a clean situation, congratulations, and your job is just to keep filing on time going forward. If the search shows the organization on the auto-revocation list, or shows nothing at all, stop and figure out why before your next fundraiser. You may need retroactive reinstatement under Revenue Procedure 2014-11 , or you may need to start fresh with a new exemption application. Either path is more paperwork than a routine annual filing, and both are worth getting right rather than guessing. Once status is confirmed, build a simple annual calendar: bank reconciliation monthly, board financial report at every meeting, 990 filing by the 15th day of the 5th month after your fiscal year ends, and state charity registration renewal on whatever schedule your state requires. A 990 tax form checklist built around your specific fiscal year takes the guesswork out of remembering which deadline applies when. This is also where a state-specific, done-for-you setup like the $99 one-time State-Personalized Treasurer Kit earns its keep. It's built to walk a brand-new treasurer through exactly this sequence, EIN check, 990 version, state registration, without guessing which form applies to a group your size.
Frequently asked questions
What is Form 990 in simple terms?
Form 990 is the annual report tax-exempt nonprofits file with the IRS instead of a regular income tax return. It discloses income, spending, and leadership. It's required under Internal Revenue Code section 6033, and most versions of it are public record anyone can look up.
What is a 990 tax form used for?
It's used to satisfy the IRS's annual reporting requirement for tax-exempt organizations, and to give the public (donors, watchdog groups, state regulators) visibility into how a nonprofit spends its money. It is not used to calculate or pay income tax, since exempt organizations generally don't owe income tax on program revenue.
What does a treasurer do?
A treasurer tracks all incoming and outgoing money, reconciles the bank account, reports finances to the board, and handles annual compliance like the Form 990 filing and state charity registration renewal. In small nonprofits, the treasurer is usually the only person who touches the bank account directly.
What is a treasurer of a club?
A club treasurer is the officer with legal responsibility for the group's finances, usually named in the bylaws with bank signing authority. The role covers recordkeeping, budget tracking, financial reporting to the board, and making sure the club meets IRS and state filing obligations.
What does a club treasurer do differently from a regular member?
A club treasurer has fiduciary duty and often legal signing authority a regular member doesn't have. That means personal accountability for accurate records and honest reporting, more than participation in fundraisers or events. Some state nonprofit statutes hold treasurers to a specific standard of care for handling funds.
Which Form 990 version does a small booster club file?
Most single-team booster clubs and school PTOs qualify for Form 990-N, the e-Postcard, because their gross receipts are normally $50,000 or less. It's an 8-question online-only form with no financial statements required. Bigger receipts push a group up to Form 990-EZ or the full Form 990.
Does a PTO have to file Form 990 even with no paid staff?
Yes. Filing requirements are based on the organization's tax-exempt status and gross receipts, not on whether it has employees. An all-volunteer PTO with 501(c)(3) status and under $50,000 in gross receipts still files the 990-N annually.
What happens if my organization never filed a 990?
If three consecutive years pass without any filing, the IRS automatically revokes tax-exempt status by law. You can check current status on the IRS Tax Exempt Organization Search and, if revoked, pursue retroactive reinstatement under Revenue Procedure 2014-11, which generally requires filing back forms and an application.
Is there a fee to file Form 990-N?
No. The 990-N is free to file through the IRS's online e-filing system. There's no paper version and no filing fee. Reinstatement after auto-revocation does carry a separate user fee, which you should confirm directly with the IRS since amounts change.
When is Form 990 due each year?
The 15th day of the 5th month after the organization's fiscal year ends. Calendar-year organizations file by May 15. A single six-month extension is available using Form 8868, filed before the original deadline, moving that date to November 15.
Can the public see our organization's Form 990?
Yes, for the 990-EZ and full 990 versions, these are public documents available through the IRS Tax Exempt Organization Search and third-party nonprofit databases. The 990-N e-Postcard itself is also searchable, though it contains almost no financial detail beyond confirming the organization is under the size threshold.
Does filing Form 990 also cover state charity registration?
No, they're separate requirements. Many states have their own charitable solicitation registration, often through the attorney general's office, and some ask for a copy of your 990 as part of that filing. Confirm your specific state's requirement, since rules vary and change.
