IRS Form 990: what it is and what treasurers actually file

Last updated 2026-07-24

What is Form 990?

Form 990 is the annual information return the IRS requires from most tax-exempt organizations, including 501(c)(3) charities and 501(c)(4) social welfare groups. It's not an income tax return in the way a business files one. Nonprofits generally don't owe income tax on money raised for their exempt purpose, but the IRS still wants an annual accounting of revenue, expenses, assets, and governance. Think of it as the price of admission for staying tax-exempt. The IRS puts it plainly: "Most tax-exempt organizations are required to file an annual return" and the specific form depends on the organization's gross receipts and total assets. There isn't one single 990 form. There's a family of them, sized to the organization. For a booster club or PTO, this matters because the version you file depends entirely on how much money passed through your accounts that year, not how much you have in the bank right now. A group that raised $48,000 selling wrapping paper and hosting a car wash files differently than one running a $600,000 athletic complex concession operation. See our form 990 overview for the full breakdown of every variant, or irs form 990 for the IRS's own framing of the requirement.

What is the 990 tax form (and why do nonprofits file it)?

The 990 tax form exists so the IRS, state charity regulators, and the public can see how a tax-exempt organization spends its money. Because 501(c)(3) and similar groups don't pay federal income tax, Congress built in a transparency requirement instead. Most 990s are public documents. Anyone can request or look up a copy through the IRS Tax Exempt Organization Search tool. For a volunteer treasurer, the practical reality is simpler than the policy reasoning: skip the filing and your organization's tax-exempt status gets pulled automatically. Internal Revenue Code section 6033(j) provides that an organization's tax-exempt status is revoked if it fails to file a required annual return or notice for three consecutive years ^[1]. There's no probation period, no phone call. The revocation happens by operation of law on the filing deadline of the third missed year. This is the single most common crisis new booster treasurers inherit: a predecessor stopped filing two or three years ago, nobody noticed, and now the group's EIN shows up on the IRS Auto-Revocation List. Fixing it means filing for reinstatement, sometimes retroactively, sometimes not, depending on which streamlined process applies under Revenue Procedure 2014-11 ^[2]. That's a topic worth its own read; start with 990-tax-form if you're staring down a revocation notice right now.

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

Form 990-N, nicknamed the "e-Postcard," is the shortest 990 variant and the one most small booster clubs and PTOs file. It's for organizations whose gross receipts are normally $50,000 or less, per Internal Revenue Code section 6033(i) ^[1]. "Normally" is an IRS term of art: it's based on a rolling average over the current and prior two years, not a hard cutoff on any single year. The 990-N asks for almost nothing: legal name, EIN, mailing address, website (if any), confirmation that gross receipts are under the threshold, and a statement that the organization hasn't dissolved. It's filed online through the IRS's e-Postcard filing system ^[1]. There's no paper option. There's also no extension available for it and no separate paper form to mail if the online system is down; you just file when you can before the deadline (though late filing itself isn't penalized the way missing 990-EZ or 990 filings can be, since there's no monetary penalty tied to a late e-Postcard). Here's the trap: gross receipts means everything that came in the door before expenses. Raise $60,000 in ticket and concession sales even if you netted $12,000 after paying for the venue and the DJ, and you're over the 990-N threshold. Most treasurers who think they qualify for the postcard actually need the 990-EZ once they add up total revenue honestly. Check 990n or form-990-n for the filing walkthrough and screenshots of the actual portal.

Which 990 form does a booster club or PTO actually file?

Normally $50,000 or less	990-N (e-Postcard)
Under $200,000 AND total assets under $500,000	990-EZ (or full 990 if preferred)
$200,000 or more OR total assets $500,000 or more	Form 990 (full)
Private foundations (rare for booster clubs)	Form 990-PF	Most school-affiliated booster clubs and PTOs land in the first two rows. A high school football booster club running a $30,000-a-year concession stand and car wash operation is a textbook 990-N filer. A district-wide PTO council managing $250,000 in fundraising and grants across several schools is very likely a full 990 filer, and probably needs a real bookkeeper or CPA, more than a volunteer with a spreadsheet. One wrinkle worth flagging: even 990-N-eligible organizations can choose to file the 990-EZ or full 990 instead if it's ever useful (say, a bank or grant funder wants to see more detail). You can always file up, just not down.

Match your gross receipts and total assets to the table below, using current IRS filing thresholds ^[1]. Always confirm current-year thresholds with the IRS since these numbers have shifted over time and can shift again. | Organization size (annual gross receipts) | Form to file |

What happens if a booster club never filed a 990 before?

If your organization has an EIN but has never filed anything, that's a real problem worth sorting out immediately, not eventually. An EIN by itself doesn't confirm tax-exempt status; plenty of booster clubs have an EIN from opening a bank account but never actually applied for or received 501(c)(3) recognition from the IRS. Start by checking the IRS Tax Exempt Organization Search tool and the Auto-Revocation List using your EIN. If your group shows up as revoked, you'll likely need to file for reinstatement using Form 1023 (or 1023-EZ if you qualify) along with the delinquent 990s, depending on which reinstatement process fits your situation under Revenue Procedure 2014-11 ^[2]. If your group never had recognized exempt status at all, you may be starting fresh with an exemption application, and any donations collected in the meantime were never actually tax-deductible to donors, which is its own conversation with your board and possibly a CPA. This is exactly the kind of mess a new treasurer walks into mid-season with zero handoff notes. If that's you, don't panic and don't guess. Confirm your status with the IRS directly before assuming anything, and loop in a local CPA who handles nonprofit reinstatements if the group's history is murky.

What does a treasurer do?

A treasurer manages an organization's money and makes sure it's tracked, reported, and legal. For a booster club or PTO, that means keeping the checkbook (or the shared spreadsheet), reconciling the bank statement every month, preparing a budget with the board, and making sure whatever tax filings are due actually get filed. Day to day, a treasurer does the boring stuff that keeps everything else running: deposits go in promptly, receipts get saved, two people count the cash box after a concession stand shift, and nobody's personal Venmo is doubling as the club's bank account. It's not glamorous work, and most of the job is invisible when it's done right and very visible when it's not. The treasurer is also usually the one who has to answer, "are we a nonprofit?" and "do we need to file something with the IRS?" Those two questions are connected. If your group has 501(c)(3) or similar status, the treasurer (or whoever the board designates) is responsible for the annual 990 filing, on top of any state charity registration or raffle license paperwork.

What is a treasurer, exactly?

A treasurer is the officer or volunteer legally and practically responsible for an organization's finances. In a small nonprofit like a booster club, that's usually one parent or community volunteer, elected or appointed by the board, serving a term that runs anywhere from one year to indefinitely (a lot of booster clubs just keep re-electing whoever's willing). Legally, the treasurer role is defined by your organization's own bylaws, not by the IRS or state law directly. Most bylaws say something like "the treasurer shall keep accurate financial records, prepare regular reports to the board, and ensure compliance with applicable tax and reporting requirements." That last clause is the one that matters here: it's usually the treasurer's bylaws-assigned job to make sure the 990 gets filed, even though the whole board is technically responsible for the organization's compliance. One important distinction: being "the treasurer" doesn't automatically make you personally liable for the club's taxes in most situations, but neglecting the job (ignoring IRS notices, commingling funds, failing to keep records) can create personal exposure in some circumstances, especially around payroll tax if the group has paid staff. If your group has any paid employees or contractors, that's a conversation for a real accountant, not a blog post.

What do treasurers do day to day, month to month, and year to year?

Daily and weekly, a treasurer deposits cash and checks promptly (don't let a shoebox of concession stand cash sit in someone's car for a week), logs every transaction, and keeps receipts organized by category. Monthly, the treasurer reconciles the bank statement against the books and gives the board a short financial report: money in, money out, current balance, anything unusual. Quarterly or seasonally (this is very booster-club-specific), the treasurer handles the big fundraiser accounting: settling up after the golf tournament, reconciling concession stand deposits against register tapes, tracking raffle ticket sales if your state requires a license for that (see our raffles-by-state coverage for your state's specific rules). Annually, the treasurer's job gets serious: prepare or review the 990 filing (or hand records to whoever prepares it), renew any state charitable solicitation registration, and help the board build next year's budget. Many state attorneys general or secretaries of state also require an annual charitable registration renewal separate from the IRS 990, so check your specific state charity office alongside the federal filing. A well-run treasurer's year ends with a clean handoff packet: bank statements, the filed 990, board minutes approving the budget, and a list of every recurring deadline. A badly-run treasurer's year ends with a shoebox and a shrug for whoever takes over next.

What does a club treasurer do differently from a corporate one?

A club treasurer, whether for a booster club, PTO, rec league, or hobby association, usually wears every finance hat a corporation splits across a controller, a bookkeeper, and a tax department. There's no payroll department to check with. There's no internal audit team. It's one volunteer (occasionally two, if you're lucky enough to have a co-treasurer) doing bookkeeping, budgeting, compliance, and reporting on nights and weekends between a day job and their kid's actual games. The stakes are also different in shape, if not always in size. A corporate treasurer worries about cash flow forecasting and debt covenants. A club treasurer worries about whether the concession stand cash box balanced, whether the raffle license got renewed before the spring carnival, and whether last year's 990-N actually got filed by whoever held the job before them. The compliance burden is real even at small scale. A $40,000-a-year booster club still has to file something with the IRS every single year, still risks auto-revocation after three missed years, and still generally needs to register with the state charity office if it solicits donations, depending on your state's rules. Size doesn't exempt you from the paperwork; it just changes which form you file.

What does a treasurer of a club actually need to keep organized?

At minimum: a dedicated bank account in the organization's name (never a personal account), a simple ledger or accounting software tracking every deposit and expense, all receipts for purchases over a reasonable threshold your board sets, prior years' filed 990s, your EIN confirmation letter, and your state charity registration paperwork if applicable. A good practice most auditors and CPAs recommend for small nonprofits is dual control on cash: two people count concession or event cash independently and both sign off before it's deposited. That single habit prevents the majority of the "we're pretty sure some cash went missing but can't prove it" situations that plague volunteer-run groups. See our financial-controls coverage for the fuller cash-handling checklist. Keep a running deadline calendar too: 990 due date (the 15th day of the 5th month after your fiscal year ends, per IRS instructions), state charity registration renewal date, raffle license renewal if applicable. Write these down somewhere that survives a treasurer transition, more than in your own head or inbox. This is exactly the gap a BoosterLedger State-Personalized Treasurer Kit is built to close: a one-time $99 packet with your state's specific forms, deadlines, and a handoff template, so the next treasurer isn't starting from a shoebox and a guess.

When is Form 990 due, and can you get an extension?

Form 990 (all versions) is due the 15th day of the 5th month after your organization's fiscal year ends. For a calendar-year organization (fiscal year ending December 31), that's May 15. For a fiscal year ending June 30, a common school-year cycle for booster clubs and PTOs, that's November 15. Organizations can request an automatic 6-month extension by filing Form 8868 before the original due date ^[3]. That extension applies to the 990, 990-EZ, and 990-PF. It does not apply to the 990-N, since there's no extension mechanism for the e-Postcard; you just file it whenever you can before your deadline, and there's no monetary penalty attached to a late 990-N specifically, though repeated non-filing still counts toward the three-year auto-revocation clock. Mark this date on every board calendar, every officer transition checklist, and honestly, on your own personal calendar with a reminder a month out. Missing one year isn't fatal. Missing three in a row triggers automatic revocation under Internal Revenue Code section 6033(j), with no appeal process for the revocation itself, only for reinstatement afterward ^[1].

What are the penalties for filing Form 990 late or not at all?

For 990 and 990-EZ filers, Internal Revenue Code section 6652(c) authorizes the IRS to assess penalties for late filing, generally calculated per day late, with amounts that scale based on the organization's gross receipts; smaller organizations face lower daily penalty caps than larger ones ^[4]. These penalties are separate from and smaller than the real risk, which is accumulating three consecutive years of non-filing. Three years of missed filings, in any combination of 990, 990-EZ, or 990-N, triggers automatic revocation of tax-exempt status under section 6033(j) ^[1], effective as of the filing due date of the third year. The statute states that an organization's exempt status is revoked if it fails to file an annual return or notice for three consecutive years, and the IRS is directed to publish and maintain a list of organizations whose status was revoked under this provision ^[1]. There's no notice-and-cure period built in; it just happens. After automatic revocation, the organization is no longer tax-exempt, donations made to it are no longer tax-deductible to donors, and in most states it also jeopardizes state-level tax exemptions and charitable registration standing. Reinstatement is possible but requires a formal application (Form 1023 or 1023-EZ in many cases) plus the delinquent returns, and the IRS's streamlined retroactive reinstatement procedures are set out in Revenue Procedure 2014-11 for organizations that apply within a certain window after revocation ^[2]. Confirm current reinstatement procedures directly with the IRS, since the specific streamlined options have changed over the years.

Frequently asked questions

What is Form 990?

Form 990 is the annual information return the IRS requires most tax-exempt organizations to file. It reports revenue, expenses, assets, and governance details. It's not an income tax bill; exempt organizations generally don't owe federal income tax on funds raised for their exempt purpose, but they still have to report annually or risk losing that exemption entirely.

What is the 990 tax form used for?

The 990 tax form gives the IRS and the public an annual look at a nonprofit's finances: how much it raised, how much it spent, and on what. Most 990s are public record. It's also the mechanism that keeps an organization's tax-exempt status active; skipping it for three straight years triggers automatic revocation under Internal Revenue Code section 6033(j).

What does a treasurer do?

A treasurer manages an organization's money: tracking deposits and expenses, reconciling bank statements, reporting to the board, building budgets, and making sure required filings like the 990 and any state charity registration get done on time. In a small booster club or PTO, one volunteer usually does all of this alone.

What is a treasurer, in plain terms?

A treasurer is the person a board designates to be responsible for an organization's finances, defined by that organization's bylaws. For a booster club or PTO, it's usually a parent volunteer who keeps the books, deposits money, and ensures tax and reporting obligations, including the 990, get met each year.

What do treasurers do differently in a small club versus a big nonprofit?

A small club treasurer handles bookkeeping, compliance, budgeting, and reporting alone, without a finance department. A large nonprofit splits those jobs across staff. The compliance requirements (990 filing, state registration) still apply at small scale, just with a simpler version of the form in most cases.

What does a club treasurer do specifically for fundraisers and events?

A club treasurer tracks all cash and check income from an event, ideally with two people counting and signing off on cash boxes, reconciles that against ticket or register totals, deposits funds promptly, and records the event's revenue and expenses for the annual budget and 990 filing.

Does a booster club or PTO have to file a 990 every year?

Yes, if it holds federal tax-exempt status, it must file some version of the 990 (990-N, 990-EZ, or full 990) every single year based on gross receipts and assets. Missing three consecutive years triggers automatic revocation of tax-exempt status under Internal Revenue Code section 6033(j).

What is the 990-N e-Postcard and who qualifies?

Form 990-N is the shortest 990 version, for organizations with gross receipts normally $50,000 or less under Internal Revenue Code section 6033(i). It's filed entirely online, asks for basic identifying information, and has no extension option. Many booster clubs and PTOs qualify, though total revenue before expenses (not net profit) determines eligibility.

What happens if a nonprofit's tax-exempt status gets auto-revoked?

The organization loses federal tax-exempt status immediately, donations to it stop being tax-deductible, and it appears on the IRS Auto-Revocation List. Reinstatement requires filing an exemption application (often Form 1023 or 1023-EZ) plus any delinquent 990s, following procedures in Revenue Procedure 2014-11. Confirm current reinstatement options directly with the IRS since procedures have changed over time.

How do you check if your booster club's tax-exempt status is still active?

Search your organization's name or EIN using the IRS Tax Exempt Organization Search tool and check the separate Auto-Revocation List. If your group appears on the revocation list, don't assume it's fine; start the reinstatement process and confirm next steps with the IRS.

Is Form 990 the same as a state charity registration?

No. Form 990 is a federal IRS filing. Most states also require separate charitable solicitation registration through the state attorney general or secretary of state's charity office, often renewed annually, with its own deadlines and forms. Confirm your specific state's requirements with your state charity office.

Can a small booster club file the full Form 990 instead of the 990-N?

Yes. Organizations eligible for the 990-N e-Postcard can choose to file the 990-EZ or full 990 instead if that's useful, for example if a bank, grant funder, or school district wants to see more financial detail. You can always file a more detailed version; you just can't file a shorter one than your size allows.
