990-N filing requirements: what booster treasurers need to know

Last updated 2026-08-14

What is Form 990, and what is the 990-N e-Postcard?

Form 990 is the annual information return that tax-exempt organizations file with the IRS to report income, spending, and activities. It's not a tax bill in the usual sense, since exempt groups don't owe income tax on money raised for their exempt purpose, but the IRS still wants an annual look at the books. Think of it as the nonprofit world's version of a tax return: proof that the organization is still operating, still exempt, and still doing roughly what it said it would do when it applied for exemption. There are several versions scaled to size. The full Form 990 is for larger organizations, Form 990-EZ is a shorter version for mid-size groups, and Form 990-N, officially the "Electronic Notice (e-Postcard) for Tax-Exempt Organizations Not Required to File Form 990 or 990-EZ," is the bare-bones version for small ones ^[1]. Most booster clubs, PTOs, and youth sports leagues fall into the 990-N bucket because their gross receipts are small. The IRS describes the threshold plainly: organizations "whose gross receipts are normally $50,000 or less" are eligible to file the 990-N instead of the longer forms ^[1]. If your group brings in more than that in a typical year, you'll need Form 990-EZ or the full Form 990 instead. For background on how the three forms relate, see form 990 and 990 tax form.

Who has to file the 990-N (e-Postcard)?

Almost every organization the IRS recognizes as tax-exempt has to file something every year, even if it did nothing but sit in a bank account. There's no dollar threshold below which a small nonprofit is excused entirely; the only question is which version of the 990 it files. If your booster club, PTO, or league is recognized as tax-exempt (most commonly under section 501(c)(3) or 501(c)(4)) and your gross receipts are normally $50,000 or less, you're eligible to file the simplified 990-N ^[1]. "Normally" is an IRS term of art here. It means your average gross receipts over the current year and the two years before it, not a strict single-year cutoff, so one unusually big fundraiser year doesn't automatically bump you up (the exact averaging rule is in the IRS instructions for the form; confirm the current-year figures with the IRS before you assume you qualify). A narrow set of organizations are exempt from filing any 990 at all, mainly churches and certain church-affiliated organizations, and some government-related entities ^[2]. Booster clubs, PTOs, and sports leagues almost never fall into that carve-out, so assume you need to file something unless a tax professional tells you otherwise.

What information does the 990-N e-Postcard actually ask for?

The e-Postcard is short by design. The IRS lists eight items it collects: your organization's legal name and any "doing business as" name, mailing address, website (if you have one), your EIN, the name and address of a principal officer, your tax year, confirmation that gross receipts are normally $50,000 or less, and a statement if the organization has terminated ^[1]. That's it. There's no balance sheet, no expense breakdown, no listing of officer compensation. It's filed entirely online through the IRS's own portal (not through mail, and not through a third-party paper form), and the IRS says it "takes only a few minutes to complete" ^[1]. If your gross receipts crept over $50,000, or if you're not sure how to calculate the average, that's the point to file the 990-EZ or full 990 instead, or get a qualified preparer to check your math. See 990-n and form-990-n for more on the mechanics of the online filing.

When is the 990-N due?

The due date is the 15th day of the 5th month after your organization's fiscal year ends. That language sounds fussy but the math is easy once you know your fiscal year. Many booster clubs and PTOs run on a school-year fiscal calendar, July 1 to June 30, which makes the filing due November 15 ^[1]. If your group instead uses a calendar fiscal year, January 1 to December 31, the 990-N is due May 15 of the following year, the same date individual tax returns are due, though it's a completely separate filing. There's no extension form for the 990-N the way there is for the longer 990 versions. If you miss the date, the IRS doesn't charge a late fee for a single missed 990-N, but the miss still counts against you (more on that below). Mark the date on whatever calendar your treasurer transition binder uses, because this is the single most common thing that falls through the cracks when a volunteer treasurer hands off the books to the next volunteer.

What happens if you miss the 990-N deadline?

One missed year usually isn't a crisis. The real danger is stacking up three in a row. Federal law (the Pension Protection Act of 2006) requires the IRS to automatically revoke the tax-exempt status of any organization that fails to file its required 990 form for three consecutive years ^[3]. The IRS's own auto-revocation page confirms the effect: revocation is automatic by law, and it applies "if you fail to file for three consecutive years" ^[4]. There's no warning letter that says "this is your last chance," though the IRS often does send notices before that point, and there's no partial credit for filing two out of three years. Once revoked, your organization is treated as a taxable entity going forward, which means donations to it may no longer be tax-deductible for donors, and the group itself could owe income tax on revenue it previously treated as exempt. The IRS maintains a public list of revoked organizations, the Automatic Revocation of Exemption List, which is searchable and updated regularly ^[5]. If your booster club shows up on it, that's your confirmation the clock already ran out.

How do you check if your organization's status has already been revoked?

Search the IRS Tax Exempt Organization Search (TEOS) tool, which lets you look up an organization by name or EIN and see its current exemption status, including whether it's on the auto-revocation list ^[5]. This takes about two minutes and should be one of the first things a new or incoming treasurer does, right alongside finding the bank statements and the EIN letter. If your group is on the list, don't panic, but don't ignore it either. Reinstatement is a real, well-documented process, it's just paperwork-heavy and the smaller-organization pathway (Revenue Procedure 2014-11) is specifically designed for exactly this situation ^[6]. It's worth checking even if you're pretty sure the club has always filed on time. Volunteer turnover is the number one cause of missed 990-Ns; the treasurer who knew the deadline moves away, retires from the board, or just gets busy, and nobody tells the new treasurer the filing exists at all.

How do you get tax-exempt status back after auto-revocation?

The IRS created a streamlined path for small organizations under Revenue Procedure 2014-11, and it's the one most booster clubs and PTOs will use. Organizations that were eligible to file the 990-N (gross receipts normally $50,000 or less) for the year revocation took effect can apply for retroactive reinstatement using a simplified process, generally by filing Form 1023 (or Form 1023-EZ if eligible) with a reduced user fee and specific language citing the revenue procedure, within 15 months of the revocation date or the date the organization appeared on the revocation list, whichever is later ^[6]. Miss that 15-month window and reinstatement is still possible, just through a different, less generous path (retroactive reinstatement without the streamlined shortcut, or reinstatement effective only from the postmark date). The specifics of which form, which user fee, and which streamlined option you qualify for depend on your organization's size and history, so confirm the current requirements directly with the IRS before filing anything; the rules and fees in Rev. Proc. 2014-11 are the anchor document but the IRS updates user fee schedules periodically. This is also the point where it's worth paying a CPA or nonprofit attorney for an hour of their time rather than guessing. Reinstatement paperwork done wrong just adds delay.

What does a treasurer do (and why does the 990-N fall on them)?

A treasurer is the volunteer or officer responsible for an organization's money: tracking income and expenses, keeping the bank accounts reconciled, reporting the financial picture to the board or membership, and handling the government paperwork that keeps the organization legally in good standing. In a booster club, PTO, or youth sports league, that last part almost always includes the annual IRS filing, because the treasurer is usually the only officer who has the EIN, the login credentials, and the fiscal-year dates memorized. What does a club treasurer do day to day? Practically, it looks like: depositing fundraiser proceeds and concession stand cash, paying vendor invoices and reimbursing volunteers, maintaining a ledger or accounting software, presenting a budget or financial report at meetings, and filing the 990-N (or coordinating with an accountant on the 990-EZ or full 990 if the group has grown past the $50,000 threshold). Some treasurers also handle state-level filings like charitable solicitation registration or raffle licensing, depending on the state and the group's activities. What does a treasurer of a club do that a bigger nonprofit would split between a bookkeeper, a CFO, and a compliance officer? Everything, usually, because most booster clubs have exactly one person willing to do this job. That's precisely why missed deadlines are so common: there's no backup system, no second person checking the calendar, and often no formal handoff when the role changes hands. If you're new in the role, it's worth reading up on 990-n filing basics and on general treasurer duties before your first fiscal year-end arrives.

Does a 990-N filing cost anything?

No. Filing the 990-N itself is free; the IRS doesn't charge a fee to submit the e-Postcard ^[1]. If you ever hire a bookkeeper, CPA, or online filing service to do it for you, that's a service fee you're paying to a third party, not an IRS charge, and for an organization that genuinely qualifies for the 990-N (gross receipts under the $50,000 threshold), it's a form simple enough that most volunteer treasurers can do it themselves in one sitting. Where costs do show up is on the back end: if your status lapses into auto-revocation, reinstatement under the streamlined Rev. Proc. 2014-11 process carries a reduced IRS user fee compared to a full Form 1023 application, but it's not zero, and the exact current fee schedule should be confirmed directly on IRS.gov before you file, since user fees are adjusted periodically ^[6].

990-N vs 990-EZ vs full 990: how do you know which one to file?

990-N (e-Postcard)	Smallest tax-exempt orgs	Normally $50,000 or less [1]
990-EZ	Small to mid-size orgs	Generally less than $200,000, and total assets less than $500,000
Full Form 990	Larger orgs	Generally $200,000 or more in gross receipts, or $500,000 or more in total assets	These thresholds come from the IRS's own instructions and are the numbers that matter for a booster club evaluating a growth year; if a big capital campaign or an unusually large tournament pushes receipts past $50,000, don't just default to filing the 990-N again out of habit. Recheck the numbers every year. For a plain-language comparison of the three forms, see 990-tax-form and irs-form-990.

The dividing line is gross receipts and, for the largest organizations, total assets. Here's the general breakdown the IRS uses to sort organizations into the right form: | Form | Who generally files it | Gross receipts threshold |

What records should you keep to make the 990-N filing easy every year?

Keep a simple year-end snapshot: total gross receipts for the fiscal year, the organization's legal name exactly as it appears on IRS records, current mailing address, EIN, and the name of whoever is serving as principal officer. That's genuinely all the 990-N needs, and if you keep it updated in a shared document (more than in one departing treasurer's head), filing takes minutes instead of an afternoon of digging through old emails. This is the kind of thing a State-Personalized Treasurer Kit is built to solve: a one-time $99 setup that gives a new treasurer the fiscal-year calendar, the EIN and filing history in one place, and the state-specific raffle and registration rules layered on top of the federal ones, so the next volunteer isn't starting from a blank spreadsheet. Even without a formal kit, the minimum viable system is a single-page "compliance calendar" taped inside whatever binder or shared drive holds the club's financial records: fiscal year-end date, 990-N due date (15th day of the 5th month after), state registration renewal date if applicable, and a note of where the EIN letter and last three years of filings live.

What if the organization was never actually recognized as tax-exempt?

Some booster clubs and parent groups operate for years assuming they're tax-exempt because they've always acted like one, run fundraisers, never paid income tax, called themselves a nonprofit, but they never actually filed for and received IRS recognition under 501(c)(3) or another exempt category. If that's your situation, the 990-N conversation is moot until you fix the underlying problem, because you can't file an annual return for an exemption you don't legally have. Check the IRS Tax Exempt Organization Search tool first ^[5]. If your organization genuinely doesn't appear, the next step is applying for exemption (typically Form 1023 or the shorter Form 1023-EZ for smaller organizations), not filing a 990-N. This is a case where paying for an hour with a nonprofit-focused CPA or attorney is worth it, since getting the application wrong can cost real time. Some booster clubs solve this a different way entirely: operating under a school district's or a national umbrella organization's tax-exempt status instead of getting their own EIN and exemption. If that's your arrangement, your filing obligations may run through that umbrella group rather than falling on your own club, so confirm which structure actually applies before assuming you need to file anything at all.

Frequently asked questions

What is Form 990?

Form 990 is the annual information return tax-exempt organizations file with the IRS covering income, spending, and activities. It comes in three main sizes: the full Form 990, the shorter Form 990-EZ, and the 990-N e-Postcard for organizations with gross receipts normally $50,000 or less ^[1]. It's not an income tax bill; it's a compliance report proving the organization is still operating within its exempt purpose.

What is a 990 tax form used for?

It's used by the IRS and the public to see how a tax-exempt organization spends its money, who runs it, and whether it's still eligible for exemption. Most versions become public record, so donors and watchdog groups can review them too. For most booster clubs, PTOs, and small leagues, the relevant version is the simplified 990-N e-Postcard ^[1].

What is the 990-N e-Postcard?

It's the shortest version of the annual IRS filing, built for tax-exempt organizations with gross receipts normally $50,000 or less. It's filed online only, asks for eight basic items like your EIN and principal officer's name, and takes a few minutes to complete ^[1]. There's no fee to file it.

What does a treasurer do?

A treasurer manages an organization's money: tracking income and expenses, reconciling bank accounts, reporting finances to the board, and handling required government filings like the annual 990-N. In a small nonprofit, the treasurer is often the only officer responsible for both the day-to-day bookkeeping and the compliance calendar.

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

A club treasurer, in a booster club, PTO, or youth league, usually handles everything a small finance department would: cash handling from bake sales and concessions, vendor payments, budget reports, and IRS/state filings, all as an unpaid volunteer with no staff support. There's rarely a backup system, which is why deadlines like the 990-N get missed during officer turnover.

Do booster clubs and PTOs have to file a 990-N every year?

Yes, if they're recognized as tax-exempt and their gross receipts are normally $50,000 or less, filing some version of the 990 annually is required, and the 990-N is the simplified option for that size ^[1]. Skipping it isn't an option even in a year with almost no activity; a $0 year still needs to be reported.

What happens after three missed years of 990-N filings?

The IRS automatically revokes tax-exempt status by operation of law once an organization fails to file for three consecutive years ^[3][4]. There's no extra warning at year three; it's automatic. Reinstatement is possible afterward through a formal application process, but the organization is treated as taxable in the meantime.

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

Search the IRS Tax Exempt Organization Search (TEOS) tool by name or EIN. It shows current exemption status and flags organizations on the Automatic Revocation of Exemption List ^[5]. This check takes a couple of minutes and is a smart first step for any new treasurer.

How much does it cost to file the 990-N?

Nothing. The IRS doesn't charge a fee for the 990-N e-Postcard itself ^[1]. Costs only enter the picture if you hire someone to file it for you, or if your status has already lapsed and you need to pay a reinstatement user fee under the streamlined process ^[6].

When exactly is the 990-N due?

The 15th day of the 5th month after your organization's fiscal year ends ^[1]. For a July-to-June fiscal year, common for school-affiliated groups, that's November 15. For a calendar fiscal year, it's May 15 of the following year.

Can I file a late 990-N?

Yes, there's no fee or penalty attached to a single late 990-N filing, and you can file it after the deadline has passed. The real risk isn't one late year; it's three consecutive missed years, which triggers automatic revocation of tax-exempt status by law ^[3][4].

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

It comes down to gross receipts and assets. 990-N covers organizations with gross receipts normally $50,000 or less. 990-EZ generally covers gross receipts under $200,000 and total assets under $500,000. The full Form 990 covers everything above those thresholds ^[1][7].

Can a booster club that isn't its own tax-exempt entity skip the 990-N?

If the club operates under a school district's or a national organization's tax-exempt umbrella rather than its own separate 501(c)(3) status, filing obligations may run through that parent entity instead. Confirm the actual legal structure before assuming either way; this varies by school district and by sport.
