IRS Form 990 explained: what booster treasurers must file

Last updated 2026-07-24

What is Form 990?

Form 990 is the annual information return that tax-exempt organizations file with the IRS to report income, spending, and basic governance details. It is not an income tax return in the way most people think about that phrase, since exempt organizations generally don't owe federal income tax on money raised for their mission. Think of it as the public accountability document. It tells the IRS, and anyone else who looks it up, how much money came in, how much went out, and whether the group is still doing what it said it would do when it applied for exemption. There isn't one single "990." There's a family of forms scaled to organization size: Form 990-N, Form 990-EZ, and the full Form 990. Which one you file depends almost entirely on your gross receipts and total assets for the year.^[1] The IRS states plainly that "most tax-exempt organizations are required to file an annual return" and that the specific form depends on the organization's financial activity.^[1] For a volunteer-run booster club or PTO, that usually means one of two outcomes: either you file the free, 8-question 990-N online, or your treasurer needs to actually assemble a small set of financial statements for the 990-EZ.

What does a treasurer do?

A treasurer is the person responsible for tracking, reporting, and safeguarding an organization's money. In a booster club, PTO, or youth sports league, that means keeping the checkbook or bank account reconciled, recording every deposit and expense, and producing financial reports the board can actually understand. So what does a treasurer do in a club, day to day? The job usually breaks into four buckets: bookkeeping (recording transactions as they happen, not months later), cash handling (concession stand deposits, raffle proceeds, membership dues), reporting (a monthly or quarterly report to the board, plus the annual 990 filing), and compliance (state charity registration, raffle permits, sales tax questions, and making sure two people, not one, ever touch cash alone). What do treasurers do that a bookkeeper doesn't? A treasurer usually has signing authority, sits on the board or reports directly to it, and is accountable for the organization's tax-exempt status. That last part is the piece new treasurers most often don't know about until they inherit a group that's already three years behind on filings. What does a club treasurer do that's specific to boosters and PTOs? Mostly it's volume of small transactions: concession cash, spirit wear sales, car wash proceeds, raffle tickets, sponsorship checks. None of it is complicated accounting, but all of it needs a paper trail, because that trail is exactly what feeds into the 990 at year end.

What is a 990 tax form, in plain terms?

A 990 tax form is the IRS's standardized report card for a nonprofit's finances and operations for one fiscal year. It asks for revenue by source (dues, donations, fundraising events, program fees), expenses by category, and a snapshot of assets and liabilities at year end. Bigger versions of the form add questions about governance, conflicts of interest, and compensation. For a small booster club, the 990-N asks for eight basic items: legal name, any other names used, mailing address, website (if any), employer identification number (EIN), the name and address of a principal officer, the tax year, and confirmation that annual gross receipts are normally $50,000 or less.^[2] That's it. No financial statements attached, no schedules, no signatures beyond the online submission itself. The 990-EZ, by contrast, asks for a full statement of revenue and expenses, a balance sheet, and several pages of questions depending on activities (fundraising events, lobbying, grants made to others). It's still shorter than the full 990, but it takes real bookkeeping to complete accurately.

Which version of the 990 does my booster club or PTO file?

Normally $50,000 or less	Any	990-N (e-Postcard)
Less than $200,000	Less than $500,000	990-EZ (or full 990)
$200,000 or more	Any	Form 990
Any amount	$500,000 or more	Form 990	This table reflects the IRS's own filing thresholds for the 990 series.[3] A private foundation of any size files Form 990-PF instead, but that's rare for a booster club or PTO structure. Here's the part treasurers miss most often: "gross receipts" means the total money coming in before you subtract expenses. If your concession stand brought in $30,000 but you spent $18,000 on inventory, your gross receipts for this test are still $30,000, not the $12,000 net. Most small booster clubs land comfortably in 990-N territory, but a big fundraising year, a large sponsorship, or a capital campaign can push a group over $50,000 without anyone noticing until filing season. See our [990](/articles/treasurer-basics/990) overview and the form 990 breakdown for more on how the family of forms fits together.

The filing threshold is based on your organization's average annual gross receipts over the current year and the two years before it, more than one snapshot year. | Gross receipts (3-year average) | Total assets | Form required |

What is Form 990-N and how do I file it?

Form 990-N, nicknamed the e-Postcard, is the simplified electronic filing for small tax-exempt organizations with gross receipts normally $50,000 or less.^[2] It's free, it's filed entirely online through the IRS's Tax Exempt Organization Search system, and it takes most treasurers under 15 minutes once they have the EIN and prior year's info handy. The IRS explicitly notes organizations "eligible to file the e-Postcard may choose to file a full return" instead, but very few small booster clubs do that voluntarily since it means more work for no real benefit.^[2] A few things that trip people up: you need an EIN before you can file, the filing must be submitted by the 15th day of the 5th month after your fiscal year ends (so for a calendar-year organization, that's May 15), and there is no paper option. If your organization has never filed before, or the person who used to file left the board without passing along login credentials, start by confirming your EIN and prior filing history in the IRS's Tax Exempt Organization Search tool before your deadline. Our 990-n guide and form 990-n walkthrough cover the actual click-by-click process.

When is the 990 due, and what if my fiscal year isn't the calendar year?

The 990 (in any version) is due on the 15th day of the 5th month after the close of your organization's fiscal year.^[4] Most school-affiliated booster clubs and PTOs run on a July 1 to June 30 fiscal year to match the school year, which makes their 990 due November 15. If your organization runs on the calendar year (January to December), the deadline is May 15 of the following year. A single extension is available: Form 8868 grants an automatic 6-month extension, moving a November 15 deadline to May 15, or a May 15 deadline to November 15.^[5] The extension has to be filed by the original due date, and it only extends the filing deadline, it doesn't extend anything related to tax payment because most of these organizations don't owe income tax in the first place. One genuinely underrated tip for new treasurers: write your organization's specific fiscal year end and 990 deadline on a physical calendar and in whatever shared document the board uses, the first week you take over. Boards rotate treasurers every year or two, and deadlines get lost in the handoff more often than any other single thing.

What happens if a booster club or PTO misses the 990 deadline?

Nothing catastrophic happens after missing one year. The real danger is missing three years in a row. Under Internal Revenue Code section 6033(j), an organization that fails to file the required annual return or notice for three consecutive years automatically loses its tax-exempt status, and that revocation happens by operation of law, with no separate IRS notice required before it takes effect.^[6] The IRS confirms this is exactly what's driven thousands of small nonprofits, especially volunteer-run booster clubs and PTOs, onto its Auto-Revocation List without anyone at the organization realizing what was happening. Once revoked, the organization is treated as a taxable entity going forward, donations made to it are no longer tax-deductible for donors, and the group typically has to reapply for exemption from scratch, which for many small groups means filing Form 1023-EZ or Form 1023 and paying the associated user fee (currently $275 for the 1023-EZ as of the IRS's published fee schedule; confirm the current fee with the IRS before filing, since these numbers do change).^[7] There is a streamlined path back for organizations that qualify: Revenue Procedure 2014-11 lays out retroactive reinstatement procedures, including a simplified option for organizations that were eligible to file 990-N or 990-EZ and are applying for reinstatement within a specific window of their revocation date.^[8] It's not automatic and it's not free, but it's a real, documented process, and plenty of booster clubs have used it. If your organization shows up on the IRS Auto-Revocation List, don't panic and don't ignore it either; the fix gets more expensive the longer it sits.

How do I check if my organization is already on the IRS revocation list?

The IRS publishes a searchable Automatic Revocation of Exemption List as part of its Tax Exempt Organization Search tool. You can search by organization name, EIN, or state, and it will show you the revocation date and prior exempt status if your group has been auto-revoked. This is worth checking the first week you take over as treasurer for any organization, even one you think is in good standing. It's not uncommon for a booster club to be running fundraisers, taking donations, and operating normally for a year or two after revocation before anyone on the board notices, simply because nobody was checking the mail or the IRS's online records during a leadership gap. If you find your organization on the list, the next move is gathering every prior year's financial summary you can find (bank statements work if formal books don't exist) and either filing the delinquent returns plus a reinstatement application, or starting fresh with a new exemption application, depending on which path costs less time and money for your specific situation. This is genuinely one of the few places where paying an accountant a few hundred dollars for an hour of guidance is worth it, since the paperwork branches depending on how many years were missed and what your gross receipts looked like in each of them.

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

Yes, almost certainly. The exemption from filing an income tax return that most people associate with small nonprofits doesn't extend to the 990 series. The IRS is direct about this: "Most tax-exempt organizations are required to file an annual return... Some organizations, however, are not required to file annual returns" and the exceptions are narrow, covering things like certain church-affiliated organizations, not small booster clubs.^[1] Even a booster club with $3,000 in the bank account and no paid staff still owes a 990-N if it has 501(c)(3) or other recognized tax-exempt status. The filing is free and takes minutes, so there's really no good reason to skip it once you know it exists. The more common problem isn't willful skipping, it's that nobody told the incoming treasurer the organization even has an EIN or exempt status, so the filing habit just quietly lapses during a leadership transition. Building the deadline into whatever handoff document your organization uses when treasurers rotate is the single cheapest fix available. If your group doesn't have a handoff document, that's worth building before your next board turnover, alongside a note of your EIN, fiscal year end, and 990 filing history.

What information do I need before I file?

Gather these before sitting down to file, whether it's a 990-N or 990-EZ: Your EIN (not your state tax ID, and not a board member's Social Security number). Your organization's legal name exactly as registered with the IRS. Your fiscal year start and end dates. A current mailing address and, if you have one, a website. The name and address of your principal officer (usually the board president or chair, not necessarily the treasurer). And for anything beyond 990-N, a full year of revenue and expenses broken out by category, plus a balance sheet showing assets and liabilities at year end. If your bookkeeping has been informal, a spreadsheet with every deposit and withdrawal for the fiscal year, categorized even loosely, is usually enough to reconstruct what the 990-EZ needs. This is exactly the kind of setup work a State-Personalized Treasurer Kit is built for: a one-time $99 packet that maps out your state's specific charity registration and raffle rules alongside a 990 filing calendar and simple categorized ledger template, so you're not rebuilding this from scratch every time a treasurer rotates off the board. It's not a substitute for an accountant or the IRS's own instructions, just a starting structure.

How does the 990 connect to state charity registration and raffle licenses?

Filing the 990 with the IRS is a federal requirement, but most states run a separate charitable solicitation registration system, and many require a copy of your most recent 990 as part of that state filing. If your booster club raises money through raffles, most states also require a separate raffle or gaming license, often through the state attorney general's office or a state gaming commission, and some of those applications also ask about your 990 filing status or exempt status letter. Because these systems don't talk to each other automatically, it's on the treasurer to keep both federal and state paperwork current. Confirm the specific registration and raffle licensing requirements with your state's charity office or attorney general, since these rules vary a lot state to state and change periodically. See our 990 tax form and irs form 990 pages for more on how the federal filing interacts with what states ask for.

Frequently asked questions

What is a treasurer?

A treasurer is the person responsible for an organization's money: recording transactions, reconciling accounts, producing financial reports, and making sure required filings like the annual 990 get done on time. In a booster club or PTO, the treasurer is usually a board member with bank signing authority, not a paid staff position.

What does a treasurer of a club do differently from a regular board member?

A club treasurer handles the actual money movement (deposits, checks, reimbursements) and the reporting that comes from it, while other board members set policy and direction. The treasurer is also usually the one accountable for keeping the organization's tax-exempt status current through timely 990 filings.

What is Form 990-N and who has to file it?

Form 990-N is the IRS's free, online 8-question annual filing for tax-exempt organizations with gross receipts normally $50,000 or less. It requires basic info like your EIN, legal name, and principal officer, and is due by the 15th day of the 5th month after your fiscal year ends.^[3]

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

All three are annual information returns for tax-exempt organizations, scaled by size. 990-N is for gross receipts normally $50,000 or less. 990-EZ generally fits organizations under $200,000 in receipts and under $500,000 in assets. The full Form 990 is required above those thresholds.^[4]

What happens if my booster club never files a 990?

Missing one year usually triggers a late notice at most. Missing three consecutive years causes automatic revocation of tax-exempt status under IRC section 6033(j), with no advance warning notice required.^[1] Reinstatement is possible but requires new applications, fees, and sometimes back-filing.

How do I know if my organization has already lost its tax-exempt status?

Search the IRS's Tax Exempt Organization Search tool, which includes the Automatic Revocation of Exemption List.^[9] Search by your organization's name or EIN. If it shows up with a revocation date, your organization needs to either reapply for exemption or pursue reinstatement under the applicable IRS revenue procedure.

Do PTOs have to file a 990 even without paid staff?

Yes, if the PTO holds federal tax-exempt status. Having no paid staff or a small bank balance doesn't exempt an organization from the annual filing requirement. Most PTOs with modest budgets simply file the free 990-N e-Postcard each year.^[2]

What is a 990 tax form used for?

It's an annual public information return that reports a tax-exempt organization's revenue, expenses, and basic governance information to the IRS. It's not a tax bill in most cases; it's an accountability document that keeps the organization's exempt status current and, for larger nonprofits, is publicly viewable.

Is there a fee to file Form 990-N?

No. Form 990-N is free to file directly through the IRS's e-filing system. There's no paper option and no processing fee. The only cost comes later if the filing is missed for three years and the organization has to reapply for exemption, which does carry a fee.^[7]

When exactly is the 990 due for a school-year booster club?

If your fiscal year runs July 1 to June 30 (common for school-affiliated groups), your 990 is due November 15. If your fiscal year matches the calendar year, it's due May 15. The rule is the 15th day of the 5th month after your fiscal year closes.^[5]

Can I get an extension on filing the 990?

Yes. Form 8868 gives an automatic 6-month extension when filed by the original due date.^[6] It only extends the filing deadline for the information return itself; it doesn't extend anything related to tax payment, which most exempt organizations don't owe anyway.

What does a treasurer do in a small club with almost no money?

Even a low-budget club treasurer still needs to track deposits and expenses, reconcile the bank account, and file the 990-N annually if the group holds tax-exempt status. Small size doesn't remove the filing requirement, it just makes the paperwork lighter.
