TL;DR
The form 990 tax return is the annual information return tax-exempt nonprofits file with the IRS. Most booster clubs and PTOs file the 990-N postcard (gross receipts under $50,000), the 990-EZ, or the full 990, depending on size. Miss it three years running and the IRS auto-revokes your tax-exempt status.
what is form 990?
Form 990 is the annual information return the IRS requires from most tax-exempt organizations, including 501(c)(3) booster clubs, PTOs, and PTAs. It's not a tax bill in the way a personal 1040 is. It's a disclosure document: revenue, expenses, board members, and program activities, all reported to the IRS and, in most cases, made public. Anyone can look up a group's past 990s on the IRS's Tax Exempt Organization Search tool [1]. The IRS actually has a family of forms under this name, and which one you file depends entirely on how much money moved through your organization that year. Get the wrong one and you've either wasted hours on paperwork you didn't need, or worse, filed something too thin and left the IRS wondering where the rest of your finances went. If your group doesn't have its own IRS determination letter yet, this whole conversation is moot until that's fixed. Confirm your exempt status and EIN with the IRS before worrying about which 990 variant applies.
what is the 990, exactly, and why does a small club need to file one?
The 990 exists because tax-exempt groups don't pay income tax, but they still owe the public (and the IRS) transparency about where donations and fundraising dollars go. Filing isn't optional just because your booster club is small or run entirely by volunteers. Every organization recognized as tax-exempt under Internal Revenue Code Section 501(c) has to file some version of the 990 every year, with very few exceptions (churches and certain church-affiliated groups are the main ones) [2]. A booster club that raised $8,000 selling concessions and a PTO that moved $400,000 through a school foundation both have a filing obligation. The version differs; the obligation doesn't. This catches a lot of new treasurers off guard. The prior treasurer quietly stopped filing three years ago, nobody noticed, and now the group's exempt status has been automatically revoked. That's a real IRS mechanism, not a scare tactic: 26 U.S.C. § 6033(j) requires automatic revocation after three consecutive years of not filing [3].
which version of form 990 does my booster club or PTO file?
| Gross receipts normally ≤ $50,000 | Form 990-N (e-Postcard) | |
|---|---|---|
| Gross receipts < $200,000 AND total assets < $500,000 | Form 990-EZ (or full 990) | |
| Gross receipts ≥ $200,000 OR total assets ≥ $500,000 | Form 990 (full) | |
| Private foundation (rare for booster clubs) | Form 990-PF | "Gross receipts" means everything that came in before you subtract expenses: ticket sales, concession revenue, raffle proceeds, membership dues, sponsorships, the works. A booster club that grossed $60,000 in concessions but only netted $12,000 after costs still has to look at the $60,000 figure, not the net. Most small booster clubs and PTOs land in the 990-N bucket. If your group is right around that $50,000 line, or if it had one unusually big fundraising year (a raffle jackpot, a big capital campaign), check the actual threshold with the IRS before assuming the postcard still applies [5]. For a plain-language walkthrough of the postcard version specifically, see 990-N. |
The version you file is set by gross receipts and total assets, not by how the group organized itself or how many kids it serves. Here's the breakdown for the tax year, based on IRS instructions [4]: | Your situation | Form you file |
what is form 990-n and how is it different from the full 990?
Form 990-N, nicknamed the e-Postcard, is the stripped-down version for organizations with gross receipts normally $50,000 or less [5]. It's filed entirely online through the IRS's Tax Exempt Organization search system, takes maybe 10 minutes, and asks for basics: legal name, EIN, mailing address, a principal officer's name, and confirmation that receipts stayed under the threshold. There's no financial detail on a 990-N. No revenue and expense breakdown, no balance sheet, no list of major donors. That's the tradeoff for being small: less disclosure, but also almost no room for error, which is exactly why treasurers of tiny booster clubs should default to it rather than over-filing a longer form. The full Form 990 and the mid-size 990-EZ ask for a lot more: a statement of revenue and expenses, a balance sheet, compensation for officers and key employees, and a section on program service accomplishments describing what the money actually paid for. If your booster club funds uniforms, travel, and equipment for 200 kids, that program description is where you actually tell that story to the IRS and the public. Read form 990-n for the mechanics of who can sign it and what info you need before you sit down to file.
when is form 990 due, and what happens if I file late?
The 990, in any version, is due on the 15th day of the 5th month after your organization's accounting period ends [4]. For a booster club running on a calendar year (January through December), that's May 15. For a school-year fiscal calendar (July through June), it's November 15. A single 6-month extension is available using Form 8868, which pushes that May 15 deadline to November 15 [6]. That's an automatic extension; you don't need a reason, just file the form before the original due date. Miss one year and nothing dramatic happens immediately. The real danger is stacking up three consecutive missed years. Under 26 U.S.C. § 6033(j), that triggers automatic revocation of tax-exempt status, no warning letter required beyond what the IRS already publishes about the rule [3]. The IRS maintains a public Auto-Revocation List, and once you're on it, your donors' contributions are no longer tax-deductible until you're reinstated [7]. Late fees for the 990-EZ and full 990 also apply per day past the deadline, though the e-Postcard itself carries no monetary penalty for lateness, just the revocation risk if it stacks up over three years [8].
what happens after auto-revocation, and how do I fix it?
If your booster club shows up on the IRS Auto-Revocation List, it means the organization lost its tax-exempt status automatically, by law, because three consecutive annual returns went unfiled. This is more common than people think; a lot of volunteer-run groups get hit because leadership turned over and nobody grabbed the filing calendar. Reinstatement isn't automatic. You have to reapply for exempt status, generally using Form 1023 (or 1023-EZ if you qualify) or Form 1024, and in many cases you can request retroactive reinstatement back to the revocation date if you file within 15 months and show reasonable cause for the lapse [9]. The IRS lays out the specific retroactive relief procedures in Revenue Procedure 2014-11 [9]. While you're in limbo, donations to your group technically aren't tax-deductible, which matters a lot if your booster club solicits parent donations or corporate sponsorships. It's a real headache, and it happens quietly during a treasurer handoff when nobody hands over the login for the IRS's e-filing portal or even mentions the filing deadline exists. For general filing mechanics beyond the postcard version, see 990 tax form and irs form 990.
what does a treasurer do?
A treasurer is the person responsible for tracking, safeguarding, and reporting an organization's money. In a booster club, PTO, or youth sports group, that's rarely a full accounting job; it's closer to careful bookkeeping plus a few compliance deadlines layered on top. Day to day, what does a treasurer do? Collect and deposit cash from concessions, dues, and fundraisers. Pay approved bills and reimburse volunteers. Keep a running ledger so the board can see the actual bank balance versus what's budgeted. Reconcile the bank statement every month, more than at year end, because errors compound fast when nobody's watching. Once a year, the treasurer (or whoever the board designates) makes sure the group's 990, in whichever version applies, actually gets filed. That single task trips up more volunteer treasurers than anything else, because it's the one deadline that doesn't repeat monthly and is easy to forget between school years.
what is a treasurer, and what does a club treasurer do specifically?
What is a treasurer, formally? It's an elected or appointed officer, usually named in the group's bylaws, who holds legal responsibility for the organization's funds. In most booster clubs and PTOs, the treasurer is one of three or four officers (often alongside a president, vice president, and secretary), and the bylaws should spell out exactly what the treasurer of a club is expected to do. What does a club treasurer do that's specific to youth sports and school groups? A few things come up constantly: handling concession stand cash (a genuine control risk, since it's often small bills changing hands fast with no receipts), managing a fundraiser's proceeds separately from operating funds, and reporting to the board at every meeting with a simple income-and-expense summary. What do treasurers do that a lot of people don't expect? They're often the one person who knows the group's EIN, bank login, and IRS filing history. If that person moves away or steps down without a handoff packet, the next treasurer starts from zero, sometimes not even realizing a 990 is overdue. That's the exact gap a written handoff process is meant to close.
what does a treasurer do in a club with a fiscal sponsor or parent PTA?
Some booster clubs aren't independently tax-exempt at all; they operate under a school's PTA, a district foundation, or another fiscal sponsor's EIN. If that's your setup, what does a treasurer do in a club differs quite a bit: you're not filing your own 990, but you still owe accurate records to whoever holds the umbrella EIN, and you should confirm in writing whose 990 covers your activity. Don't assume. Ask the sponsoring organization directly whether your booster club's income and expenses are included on their 990, and get that answer in writing, not a verbal assurance from a departing officer. If your group actually has its own EIN and its own IRS determination letter, you almost certainly have an independent filing obligation regardless of any informal relationship with the school. Mixing this up is one of the most common ways small clubs end up auto-revoked without knowing it. Everyone assumed the school's PTA was filing on their behalf, nobody confirmed it, and three years later the club is on the IRS revocation list under its own EIN.
what records do I need before I sit down to file the 990?
Before filing any version of the 990, gather your organization's EIN, the prior year's filed return (if one exists, so you can match formatting and prior-year figures), a full income and expense summary for the fiscal year, a current list of board members and officers, and your bank statements reconciled through year end. For the 990-EZ or full 990, you'll also need a breakdown of program service accomplishments (what the money funded: uniforms, travel, equipment, scholarships), any compensation paid to officers or contractors over IRS thresholds, and details on any unrelated business income if your group sells anything unrelated to its exempt purpose in volume. A lot of this becomes far easier if your bylaws and financial policies already require monthly bank reconciliations and a simple chart of accounts. If your club is starting that structure from scratch, a [990](/articles/treasurer-basics/990) checklist built for booster-club-scale finances (as opposed to a full corporate accounting system) saves real hours. This is also where a $99 State-Personalized Treasurer Kit earns its keep: it bundles the bylaws language, reconciliation templates, and filing calendar so a new treasurer isn't rebuilding these systems from a blank page. Find it at /treasurer-kit-builder.
does my state require anything besides the federal form 990?
Filing the federal 990 doesn't automatically satisfy your state. Most states run a separate charitable solicitation registration system, and many require an annual renewal, sometimes with a copy of your 990 attached, sometimes with a separate state-specific financial form. Requirements genuinely differ by state, and they change, so confirm the specifics with your state's charity registration office or attorney general's office rather than relying on last year's assumption. Some states exempt very small organizations below a certain revenue threshold; others don't distinguish by size at all. If your booster club runs a raffle, that's usually an entirely separate license from a different state agency, on its own renewal cycle. Treat the federal 990 and your state charity registration as two separate checklist items with two separate deadlines, even if they land in the same season. Missing one doesn't excuse missing the other, and state charity offices do send follow-up notices, sometimes with their own late fees.
Frequently asked questions
What is form 990 in simple terms?
Form 990 is the annual information return the IRS requires from most tax-exempt nonprofits, including booster clubs and PTOs. It reports income, expenses, and board information to the IRS and, in most cases, to the public. It's not a tax bill; it's a disclosure document proving the organization is still operating within its exempt purpose.
What is the 990 threshold for gross receipts?
Organizations with gross receipts normally $50,000 or less file the short 990-N e-Postcard. Between $50,000 and $200,000 in receipts (with assets under $500,000), the 990-EZ or full 990 applies. At $200,000 or more in receipts, or $500,000 or more in assets, the full Form 990 is required, per IRS instructions [4].
What is a 990 tax form used for by a school booster club?
A booster club uses its 990 to report the year's fundraising income, expenses (uniforms, travel, equipment), and officer information to the IRS. It keeps the club's 501(c)(3) status active and lets donors verify their contributions were tax-deductible. Skipping it for three straight years triggers automatic revocation under 26 U.S.C. § 6033(j) [3].
What does a treasurer do in a PTO or booster club day to day?
A treasurer deposits cash from fundraisers and dues, pays approved bills, reimburses volunteers, keeps a running ledger, and reconciles the bank account monthly. Once a year, the treasurer makes sure the correct version of Form 990 gets filed on time, which is the single deadline most volunteer treasurers forget.
What is a treasurer's legal responsibility versus a bookkeeper's?
A treasurer is usually a named officer under the bylaws with fiduciary responsibility for the organization's funds and reporting duties, including signing off on filings. A bookkeeper, paid or volunteer, may handle data entry and reconciliations, but the treasurer typically remains accountable to the board and to the IRS for accuracy.
What do treasurers do if the club has been auto-revoked?
The treasurer typically leads reinstatement: filing the appropriate exemption application (Form 1023 or 1023-EZ, or 1024), requesting retroactive reinstatement if within 15 months of revocation under Revenue Procedure 2014-11, and notifying the board and donors about the interim loss of deductibility [9].
What does a club treasurer do differently from a corporate treasurer?
A club treasurer manages much smaller sums, often cash-heavy (concessions, raffle tickets, dues), with volunteer turnover every year or two. The core duties (recordkeeping, reconciliation, reporting) are similar to any treasurer role, but the compliance stakes are lower per dollar and the recordkeeping systems need to survive a full leadership handoff every single year.
Is form 990-N really free to file?
Yes. Form 990-N is filed directly through the IRS's online system with no filing fee. You'll need the organization's EIN, tax year end date, legal name and mailing address, any other names the group uses, a principal officer's name and address, and confirmation that gross receipts are normally $50,000 or less [5].
When is the form 990 tax return due each year?
The 990, in any version, is due the 15th day of the 5th month after the organization's fiscal year ends: May 15 for calendar-year filers, November 15 for July-to-June fiscal years. A single automatic 6-month extension is available via Form 8868 [6].
Does a small PTO under $5,000 in revenue still have to file?
Almost always, yes. The 990-N postcard applies down to essentially any tax-exempt organization with receipts under $50,000, with very few exceptions like churches. There's no general small-dollar exemption from filing entirely; confirm your group's specific status with the IRS.
Can the treasurer file the 990 alone, or does the board need to approve it?
The IRS only requires a principal officer's signature or authorization to file, but most bylaws and good practice call for board review before submission, especially for the full 990 or 990-EZ where financial detail and officer compensation get disclosed publicly.
What happens to donor tax deductions if our 990 filing lapses?
If your organization gets auto-revoked for missing three consecutive years, donations made after the revocation date generally aren't tax-deductible until reinstatement is granted, though retroactive reinstatement under Revenue Procedure 2014-11 can restore deductibility back to the revocation date in qualifying cases [9].
