TL;DR
Form 990 is the annual information return the IRS requires from tax-exempt organizations. Most booster clubs and PTOs file the simplest version, the 990-N, if gross receipts are normally $50,000 or less. Miss it three years running and the IRS automatically revokes your tax-exempt status, no warning letter required.
What is Form 990?
Form 990 is the annual information return that tax-exempt organizations file with the IRS instead of a corporate income tax return. It's not a bill. Most booster clubs, PTOs, and youth sports leagues owe zero federal income tax, but the IRS still wants a yearly report on money in, money out, and who's running the show. The IRS describes it plainly: organizations exempt from income tax under section 501(a) "generally must file an annual information return" and the specific form depends on the organization's financial activity [1]. There are four versions in the family: the 990-N (postcard), 990-EZ, full 990, and 990-PF for private foundations. Almost no volunteer booster club needs the full 990 or the 990-PF. Think of it as the IRS's way of keeping a pulse on the 1.8 million or so tax-exempt organizations registered in the U.S. If you stop filing, the IRS assumes you've gone dark, and eventually it revokes your exemption automatically. More on that below, because it's the single most common crisis that lands on a new volunteer treasurer's desk.
What is a 990 tax form, in plain terms?
A 990 tax form is a disclosure document, not a tax payment form. It reports revenue, expenses, assets, board members, and (for the bigger versions) executive compensation and major activities. Anyone can look up a filed 990 on the IRS's Tax Exempt Organization Search tool [2], so treat it as a public document from the start; parents, school administrators, and even competing booster clubs can and do pull these. For a small booster club, the entries are simple: total cash received from concessions, car washes, spirit wear, and sponsor donations; total spent on uniforms, tournament fees, and equipment; and a yes/no attestation that gross receipts stayed under the threshold for the simplified 990-N. There's no line for "we're not sure, we lost the shoebox of receipts," so the quality of the filing depends entirely on what the treasurer tracked all year. If your group has never filed anything and you're not sure whether it even has its own EIN or 501(c)(3) status, that's a separate first step. Filing a 990 assumes the organization already has recognized tax-exempt status; if it doesn't, start with that question before worrying about which 990 variant applies.
What is the 990-N and who has to file it?
The 990-N, nicknamed the "e-Postcard," is the simplest option and the one most booster clubs and PTOs use. It applies to organizations whose gross receipts are normally $50,000 or less [3]. It's filed entirely online through the IRS's Form 990-N electronic filing system, takes about ten minutes once you have the organization's EIN, and asks for basics: legal name, address, EIN, tax year, confirmation that gross receipts are $50,000 or under, and the name of a principal officer. There's no financial detail beyond that yes/no threshold check. No income statement, no balance sheet. That's exactly why it's called a postcard. "Normally $50,000 or less" is a specific IRS test, not a strict single-year cutoff. The IRS calculates it as an average over the current year and the two prior years (or a prorated average for younger organizations) [3]. So one unusually good fundraising year, say a $60,000 gala, doesn't automatically bump you out of 990-N eligibility if your three-year average still lands under $50,000. Track your last three years of gross receipts before assuming you've outgrown the postcard. One trap: gross receipts means everything that comes in before subtracting expenses. A concession stand that brings in $40,000 and spends $35,000 on inventory has $40,000 in gross receipts, not $5,000 in "profit." A lot of volunteer treasurers get this wrong and file (or fail to file) based on net income instead.
What triggers the 990-EZ or full Form 990 instead?
| 990-N | Small booster club, PTO | Normally $50,000 or less [3] | EIN, name, address, tax year, receipts confirmation | |
|---|---|---|---|---|
| 990-EZ | Mid-size club with paid programs | Under $200,000 and assets under $500,000 [4] | Summary financials, officer list, program summary | |
| Form 990 | Larger nonprofit, regional league | Above 990-EZ thresholds [4] | Full financials, compensation, governance detail | Most single-team or single-school booster clubs never leave the 990-N tier. A district-wide athletic booster organization running multiple sports, hiring paid coaches, or holding a real endowment might cross into 990-EZ or full 990 territory. If you're not sure which bucket you're in, run the three-year average calculation first; guessing wrong wastes time on the wrong form. |
Once average gross receipts cross above $50,000, the postcard is no longer an option. The next tier is generally the 990-EZ, which the IRS allows for organizations with gross receipts under $200,000 and total assets under $500,000 at year end [4]. Above those numbers, you're into the full Form 990, which is a much longer document covering compensation, related-party transactions, and detailed program service accomplishments. Here's a quick comparison of the three most relevant versions for booster clubs: | Form | Typical filer | Gross receipts threshold | What it asks for |
What happens if a booster club doesn't file a 990 at all?
This is the scenario that brings most new treasurers to search for this topic in the first place. Federal law is unforgiving here: if a tax-exempt organization fails to file the required return or notice for three consecutive years, its tax-exempt status is automatically revoked as of the filing due date of the third year [5]. No warning letter is legally required before this happens, and the IRS does publish a running list of revoked organizations. The consequence isn't abstract: once revoked, the organization is treated as a taxable entity, donations to it are no longer tax-deductible for donors, and many states will also flag or suspend the group's state-level exemption or charitable registration. The fix is called reinstatement, and the IRS has a formal process for it, including a streamlined "retroactive reinstatement" for organizations that qualified for 990-N or 990-EZ in the year revocation occurred [6]. It usually means filing Form 1023 or 1023-EZ again along with any past-due 990s, and there is a filing fee ($275 for Form 1023-EZ as of the IRS's current fee schedule, confirm with the IRS for the current amount ). It's fixable. It's just a paperwork and patience problem, not a permanent death sentence, but plenty of booster clubs sit revoked for years because nobody realized it happened. If your club just took over a set of books and you're not 100% sure the group's exemption is current, check the IRS's Tax Exempt Organization Search tool [2] before you do anything else. It takes two minutes and tells you immediately whether you're dealing with a normal filing year or a revocation cleanup project.

What is a treasurer, and what does a treasurer do?
A treasurer is the volunteer (or occasionally paid staff member) responsible for an organization's money: tracking it, reporting it, and keeping it safe. In a booster club, PTO, or youth sports league, the treasurer is usually the only person who touches both the bank account and the books, which is exactly why the role carries outsized risk if the person before you left a mess. What does a treasurer do in a club, concretely? The job breaks into a few recurring buckets: recording income and expenses as they happen, reconciling the bank statement every month, preparing a budget or financial report for board meetings, making sure required filings (like the 990) go in on time, and handing off clean records to the next person. None of it is glamorous. Almost all of it is preventable-crisis-avoidance if done consistently. What does a club treasurer do that's different from a corporate bookkeeper? Scale and stakes, mostly. A booster club treasurer might manage $8,000 a year moving through a concession stand, a raffle, and a spirit-wear sale, all cash-heavy, all volunteer-run, with no professional oversight unless the board insists on one. That combination (real money, low oversight, high turnover) is exactly why the IRS's 990 filing requirement and basic cash-handling controls matter so much for small groups: there's rarely a second set of eyes.
What does a treasurer of a club actually do day to day and year to year?
Day to day, it's small: deposit the concession stand cash, log the Venmo payments from the spirit-wear order, pay the referee invoice, keep receipts. Month to month, it's reconciliation: does the bank statement match the ledger, and if not, why not. Year to year, it's the bigger-picture stuff: build next year's budget, file the 990 (or confirm someone else did), renew any state charitable registration, and prepare a handoff packet for whoever takes over next. A reasonable annual checklist looks like this: - Reconcile the bank account every month, more than at year end
- Track gross receipts running total so you know which 990 version applies
- File the 990-N, 990-EZ, or full 990 by the deadline (the 15th day of the 5th month after the organization's fiscal year ends) [1]
- Renew or confirm state charitable solicitation registration if your state requires it (confirm with your state charity office; requirements vary widely)
- Keep a paper or digital folder of bylaws, EIN letter, prior 990s, and bank statements that survives a change in treasurer That last point is where a lot of booster clubs quietly fail. The treasurer who filed the 990-N for the last four years graduates, moves, or just steps down, and the incoming treasurer has no idea an EIN even exists, let alone that a filing is due every year. That's the exact gap a 990n reference sheet or a written handoff packet is meant to close.
What is form 990 required for beyond just the IRS?
Filing the 990 (in whichever version fits) isn't only about staying on the IRS's good side. Many states use 990 data as part of their charitable solicitation registration requirements, meaning a lapsed federal filing can cascade into a state-level compliance problem too. If your booster club runs a raffle, sells raffle tickets across town, or solicits donations broadly, your state attorney general's charity office may ask for a copy of the most recent 990 or 990-N confirmation as part of registration or renewal (confirm with your state charity office; this varies by state and by how the club is structured). School districts and athletic departments increasingly ask booster clubs to show proof of active 501(c)(3) status and current 990 filings before allowing the group to fundraise under the school's name or use school facilities for events. That proof is exactly what the IRS's Tax Exempt Organization Search tool [2] provides for free, and it's worth printing a screenshot of your organization's listing once a year for your own files. Donors sometimes ask too, especially for larger gifts. A parent writing a $2,000 check for a scholarship fund may want to confirm the deduction is legitimate before handing over the money, and a current 990 filing (or at least active-status confirmation) is the easiest way to answer that without a long explanation.
How do you actually file the 990-N or 990-EZ?
For the 990-N, everything happens through the IRS's e-Postcard filing system online. You'll need the organization's EIN, legal name and mailing address, tax year, the name and address of a principal officer, and confirmation of the website (if any) and that gross receipts are $50,000 or less. There's no paper option and no fee. Most treasurers can finish it in one sitting if they have the EIN handy; the whole friction point is usually digging up login credentials or the EIN from a prior year's records. For the 990-EZ or full Form 990, the process is meaningfully bigger: it requires actual financial statements, a list of officers and directors, and (depending on size) additional schedules covering things like fundraising events, related organizations, or compensation over certain thresholds. Most volunteer treasurers at this size either bring in a CPA for an hour of review or use nonprofit-specific filing software; doing a 990-EZ cold, with no accounting background, is where errors creep in. Regardless of which version applies, the deadline is the same formula: the 15th day of the 5th month after the close of your organization's fiscal year [1]. A club running July 1 to June 30 files by November 15. A club on a calendar year files by May 15. Miss it, and you get one automatic 6-month extension available via Form 8868 for the 990-EZ and full 990 (the 990-N has no extension option, but also no penalty for a single late filing, though three years late triggers revocation regardless) .
What records does a treasurer need before filing?
Before you sit down to file anything, gather four things: the organization's EIN (not the school's, not a board member's Social Security number), a running total of gross receipts for the tax year, the name of whoever counts as principal officer, and last year's filed 990 or 990-N confirmation email as a template. If any of those are missing, that's the actual first task, not the filing itself. A missing EIN means calling the IRS Business & Specialty Tax Line or checking old bank paperwork, since the account was opened with that number. A missing prior filing means checking the 990 tax form history via the IRS's public search tool before assuming nothing was ever filed. This is also the moment to build (or rebuild) a simple year-round ledger: date, source, amount, category, for every dollar in and out. Waiting until the filing deadline to reconstruct a year of concession-stand cash and Venmo transfers from memory is how errors and omissions creep into an otherwise simple postcard filing.
Frequently asked questions
What is Form 990?
Form 990 is the annual information return tax-exempt organizations file with the IRS instead of a corporate income tax return. It reports revenue, expenses, and leadership information. The IRS requires some version of it from virtually every 501(c)(3), including small volunteer-run booster clubs, based on gross receipts [1].
What is a 990 tax form?
A 990 tax form is a public disclosure document, not a bill. It shows how much money an exempt organization took in and spent, who ran it, and whether it stayed within size limits for simplified filing. Anyone can view a filed 990 through the IRS's Tax Exempt Organization Search tool [2].
What is the 990-N and does my booster club need it?
The 990-N (e-Postcard) is the simplified filing for tax-exempt organizations with gross receipts normally $50,000 or less, averaged over three years [3]. Most single-school booster clubs and PTOs qualify. It's filed free online in about ten minutes with no financial detail beyond the receipts confirmation.
What does a treasurer do?
A treasurer tracks all money coming in and going out of an organization, reconciles the bank account monthly, prepares financial reports for the board, and handles required filings like the annual 990. In a small nonprofit, the treasurer is often the only person overseeing both the bank account and the books.
What is a treasurer, exactly, in a volunteer organization?
A treasurer is the officer legally and practically responsible for an organization's finances: cash handling, record keeping, budgeting, and compliance filings. In booster clubs and PTOs the role is almost always volunteer, unpaid, and rotates every one to three years, which makes clean handoff records especially important.
What do treasurers do that other board members don't?
Other board officers vote on decisions and oversee programs; the treasurer is the one who actually touches the money, reconciles it against bank statements, and signs off on the accuracy of financial reports. The treasurer is also usually the one named as principal officer on the 990 filing.
What does a club treasurer do differently from a corporate accountant?
A club treasurer manages far smaller sums, typically thousands rather than millions, but with less oversight: no finance department, no internal audit team, often just one volunteer and a shoebox of receipts. The stakes (IRS revocation, lost donor trust) can still be serious even at small dollar amounts.
What happens if a nonprofit doesn't file a 990 for three years?
The IRS automatically revokes tax-exempt status after three consecutive years of missed filings, with no separate warning letter required by law [5]. The organization then owes possible income tax and donors can no longer deduct contributions until status is reinstated through a formal IRS application process [6].
Can a revoked booster club get its tax-exempt status back?
Yes. The IRS offers reinstatement, including a streamlined retroactive option for organizations that qualified for 990-N or 990-EZ filing in the revocation year [6]. It generally requires refiling Form 1023 or 1023-EZ (fee $275 for the EZ version, confirm current fee with the IRS [7]) along with catching up on past-due 990s.
When is Form 990 due each year?
The 990, in any version, is due the 15th day of the 5th month after the organization's fiscal year ends. A calendar-year filer (January to December) files by May 15; a school-year filer (July to June) files by November 15 [1]. The 990-EZ and full 990 can get a six-month extension via Form 8868.
Does a $0-income booster club still have to file a 990?
Yes. Even organizations with no income and no activity in a given year still owe a 990-N filing if they hold active tax-exempt status, since the requirement is based on organization status, not on whether any money moved. Skipping it counts toward the three-year revocation clock the same as any other year.
How do I know which 990 version my booster club should file?
Calculate your average gross receipts over the current year plus the two prior years. Under $50,000 average, file the 990-N. Under $200,000 with assets under $500,000, the 990-EZ generally applies. Above that, the full Form 990 is required [3][4]. Gross receipts means total income before expenses, not net profit.
Where can I check if my organization's 990 filings are current?
Use the IRS's Tax Exempt Organization Search tool at irs.gov [2]. It shows filing status, whether the organization is currently listed as revoked, and links to prior filed 990s. It's free, takes about two minutes, and is the first thing a new treasurer should check when taking over the books.
