990-N: what it is and how booster treasurers file it

Last updated 2026-07-24

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

Form 990-N, nicknamed the "e-Postcard," is the smallest version of the annual information return that tax-exempt organizations file with the IRS. It's for organizations whose annual gross receipts are normally $50,000 or less. The IRS says flatly: "Most tax-exempt organizations, other than churches, are required to file an annual return with the IRS. Organizations with gross receipts of $50,000 or less can use Form 990-N." ^[1] That covers a lot of booster clubs, PTOs, small youth sports leagues, and volunteer-run nonprofits. If your treadmill fund raised $18,000 last year selling concessions and running a car wash, you're almost certainly a 990-N filer. If you cleared $60,000 because of a big raffle year, you've likely bumped up to a 990-EZ or full 990 instead. Gross receipts means everything coming in before expenses, not net profit, so a $40,000 gala that cost $15,000 to throw still counts as $40,000 in gross receipts, not $25,000. There's no paper version. You file 990-N entirely online through the IRS's electronic system. There's no fee to file it either. It takes most treasurers under ten minutes once they have their EIN and login handy.

What is Form 990, exactly?

990-N (e-Postcard)	Smallest orgs	Gross receipts normally $50,000 or less [1]
990-EZ	Mid-size orgs	Gross receipts under $200,000 and total assets under $500,000 [2]
990 (full)	Larger orgs	Gross receipts $200,000 or more, or assets $500,000 or more [2]
990-PF	Private foundations	All private foundations, regardless of size	So when someone asks "what is a 990 tax form," the honest answer is that it isn't one form. It's a tiered reporting system, and the 990-N is the version built for volunteer-run groups that don't have a bookkeeper on staff. For more on the full-size version, see form 990 and irs form 990.

Form 990 is the umbrella name for the whole family of annual information returns that tax-exempt organizations file to report income, expenses, and activities to the IRS. It's not a tax bill. Most 501(c)(3) and 501(c)(4) organizations owe no income tax on mission-related revenue, so the 990 exists to keep the organization accountable and public, not to calculate a tax due. There are four flavors, and which one you file depends on your gross receipts and total assets: | Form | Who files it | Rough threshold |

What is the 990 used for, and why does the IRS care?

The 990 series exists because tax-exempt status is a privilege, not a right, and the public (including donors, watchdog groups, and state charity regulators) is entitled to see basic financials. Sites like GuideStar/Candid and ProPublica's Nonprofit Explorer pull directly from 990 filings, which is why a stranger can look up your booster club's revenue history from a browser. For 990-N filers specifically, there isn't much to see because the form itself is only eight data points: your EIN, tax year, legal name and address, other names the organization uses, the name and address of a principal officer, your website (if you have one), confirmation your gross receipts are $50,000 or less, and confirmation you haven't dissolved ^[1]. There's no revenue-and-expense schedule, no board list, none of the financial detail a 990-EZ or full 990 requires. It's genuinely a postcard, not a return in the traditional sense. That simplicity is the whole point. Congress created the e-Postcard option in the Pension Protection Act of 2006 (Pub. L. 109-280, section 1223), largely because small volunteer groups were failing to file anything at all and getting caught in mass revocations. The text of that law is codified in the U.S. Code at 26 U.S.C. 6033(i), which sets the annual electronic notice requirement for organizations not otherwise required to file ^[3]. The 990-N was designed to be so easy that a parent with no accounting background can knock it out during a lunch break.

What does a treasurer do? The core job in plain terms

A treasurer is the person legally and practically responsible for an organization's money: tracking it, reporting on it, and keeping it separate from anyone's personal funds. For a booster club, PTO, or youth sports league, that usually means a handful of concrete duties repeating on a monthly or seasonal cycle. What treasurers do, in practice: keep a checkbook or accounting software current, reconcile the bank statement every month, collect and organize receipts, write checks with a second signer when the bylaws require it, prepare a treasurer's report for board meetings, file the annual 990-N (or hand it to whoever does), track any state charitable registration or raffle license renewal, and hand off a clean set of books to the next treasurer when their term ends. The honest version most articles skip: a lot of the job is just showing up consistently. Reconciling a bank statement takes 20 minutes if you do it monthly and three stressful hours if you let it pile up for a year. Treasurers who fail aren't usually dishonest, they're just overwhelmed and behind, which is exactly how 990-N deadlines get missed and how organizations end up auto-revoked.

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

A club treasurer (booster club, PTO, rec league, alumni association) does the same core job as any nonprofit treasurer, just at a much smaller scale and usually as an unpaid volunteer serving a one- or two-year term. What does a treasurer of a club do that a corporate CFO doesn't? Mostly this: they're the entire finance department. There's no controller, no AP clerk, no outside auditor unless the bylaws or a state law requires one. That means a club treasurer wears every hat. They deposit the concession stand cash, categorize the Venmo payments from team parents, write the check to the uniform vendor, and then turn around and file the government paperwork too. Because the job rotates every year or two, continuity is the biggest risk. A club treasurer who inherits a shoebox of unlabeled receipts and no login to the IRS system is starting from a real deficit, and that's usually where auto-revocation happens: nobody remembered the EIN or the filing deadline because the prior treasurer just vanished after graduation season. A decent handoff packet (EIN, bank info, prior 990-N confirmations, state registration numbers) solves 80% of this problem. If your organization doesn't have one, building it is the single best hour you'll spend this year.

When is the 990-N deadline, and what happens if I miss it?

Form 990-N is due by the 15th day of the 5th month after the close of your organization's fiscal year ^[1]. If your fiscal year matches the calendar year (ends December 31), that's May 15. If your booster club runs on a school-year fiscal calendar ending June 30, your 990-N is due November 15. Miss one deadline and nothing dramatic happens immediately; there's no late fee for 990-N specifically. But the IRS's rule is unforgiving over time: "Organizations that fail to file required Form 990 series returns for three consecutive years automatically lose their tax-exempt status" ^[4]. That's the auto-revocation cliff, and it doesn't require any human at the IRS to review anything. It's automatic, computer-triggered, and it hits volunteer groups constantly because leadership turns over and nobody notices three straight years slipping by. Once revoked, you're off the IRS's list of tax-exempt organizations, donations to you are no longer automatically tax-deductible, and depending on your state, you may owe income tax and lose state tax exemptions too. Recovery is possible through retroactive reinstatement (Rev. Proc. 2014-11 lays out streamlined options for small orgs), but it means refiling, sometimes paying a reduced application fee, and living with a gap in your public status in the meantime. Check current instructions at irs.gov/charities before assuming which streamlined path applies to you.

How do I actually file the 990-N e-Postcard?

You file through the IRS's electronic filing system for the e-Postcard, accessible from the IRS charities and nonprofits page ^[5]. You'll need an IRS-issued Employee Identification Number (EIN), which is different from a Social Security number and different from any state tax ID. Step by step, roughly: create or log into your IRS.gov filing account, select 990-N, enter your EIN, confirm your tax year, enter the organization's legal name and mailing address, list any other names the organization does business under, name a principal officer, note your website if you have one, and confirm your gross receipts are $50,000 or less and that you haven't terminated. Submit. You'll get a confirmation the IRS accepted it (or a rejection notice telling you what to fix, usually a name or EIN mismatch). Save that confirmation. It's your proof of filing, and the next treasurer will want it in the handoff file. There's no extension request process for 990-N the way there is for larger returns, so if you're going to be late, be late and file as soon as you can rather than waiting for a form that doesn't exist. For background on the larger forms your group might eventually graduate into, see 990 tax form and n 990 form.

What counts toward the $50,000 gross receipts limit?

Gross receipts means total revenue before subtracting any expenses: ticket sales, concession sales, raffle ticket sales, sponsorship payments, membership dues, fundraiser proceeds, grants, and donations all count. The IRS defines an organization's gross receipts as "normally $50,000 or less" using a formula based on averaging the current year and prior two years for organizations that have been around three years or more, or a prorated test for newer organizations ^[1]. That averaging detail trips people up. If your booster club made $35,000, $40,000, and $70,000 over three years because of one huge alumni gala, the three-year average could push you over the $50,000 line even though two of those three years were well under it. In that case you'd need to check the IRS's specific gross receipts test (in the Instructions for Form 990-EZ, which spells out the exact three-year averaging formula ^[6]) rather than just looking at last year's bank statement, and possibly file the 990-EZ instead. When in doubt, treasurers should run the actual three-year average rather than eyeballing it, and confirm the current threshold with the IRS since these numbers are set in the Internal Revenue Code and instructions rather than fixed forever.

What does a PTO treasurer do that's different from a booster club treasurer?

Functionally, almost nothing differs. A PTO (parent-teacher organization) treasurer and a booster club treasurer both file the same 990-N if they're under the gross receipts threshold, both need an EIN, both need to track fundraiser income and vendor payments, and both face the same three-year auto-revocation clock. The one real difference is often the money mix. PTOs frequently handle teacher grant reimbursements, school supply fund drives, and Box Tops/Amazon-style rebate programs, which means more small, frequent transactions to reconcile. Booster clubs tend to have bigger, lumpier fundraisers (a golf tournament, a raffle, a car wash weekend) that need tighter cash-handling controls at the point of collection since more cash changes hands in a shorter window. Both organization types run into the same paperwork gaps: no one knows the EIN, the state charitable registration lapsed, or last year's treasurer left with the QuickBooks password. That's a governance problem, not a 990-N problem, and it's worth fixing separately from tax filing.

Do I need an accountant to file the 990-N?

No. The 990-N is deliberately simple enough that most volunteer treasurers file it themselves without paying anyone. It's eight data fields, no financial statements, no schedules. If your organization is genuinely under the $50,000 threshold, hiring a CPA for this specific form is usually a waste of money. Where professional help earns its cost: if you're not sure which form you owe (990-N vs 990-EZ vs full 990), if you're recovering from auto-revocation and need to figure out the retroactive reinstatement process, if you have unrelated business income that might trigger a separate 990-T filing, or if your state's charity registration paperwork is genuinely confusing. Those situations involve judgment calls a simple e-Postcard doesn't require. This article, like the rest of BoosterLedger, isn't tax or legal advice and we're not accountants or a law firm. For anything beyond a straightforward 990-N filing, or for state-specific charity registration and raffle licensing questions, confirm the details with the IRS and your state charity office directly, since rules vary by state and change over time.

What if my organization is new and doesn't have 501(c)(3) status yet?

Filing a 990-N doesn't grant tax-exempt status; it's an annual filing requirement that assumes you already have recognized exempt status (or are treated as tax-exempt without having formally applied, which is possible for very small organizations under IRC 508(c)). If you haven't filed for exemption yet, the process starts with getting an EIN from the IRS, then, in most cases, filing Form 1023 or the streamlined Form 1023-EZ to apply for 501(c)(3) recognition. Many small booster clubs and PTOs operate for years as unincorporated associations without ever formally applying, assuming they're automatically exempt because they're small and volunteer-run. That assumption is risky. Without formal 501(c)(3) recognition, donors can't reliably claim their donations as tax-deductible, and the organization may not qualify for grants or the state sales-tax exemptions many nonprofits rely on for fundraiser purchases. If you're not sure whether your organization has ever been formally recognized, look it up on the IRS Tax Exempt Organization Search tool . It's free and takes thirty seconds.

How do I check if my organization already lost its status?

Use the IRS Tax Exempt Organization Search tool at irs.gov, which lets you search by name or EIN and shows current exempt status, plus a separate list of organizations that have had their exemption automatically revoked . This is the fastest way for an incoming treasurer to find out, in under a minute, whether the prior treasurer kept up with filings. If you find your organization on the auto-revocation list, don't panic, but don't ignore it either. You'll need to look into reinstatement, which for small organizations often uses a streamlined retroactive process under Rev. Proc. 2014-11, though the exact path and any user fee depend on your organization's size and how long it's been revoked. Confirm current procedures directly with the IRS before filing anything, since fees and processes get updated. This is also the first thing a new treasurer should check during handoff, before touching the checkbook. It takes less time than opening a new bank account and it tells you immediately whether you're inheriting a clean filing history or a multi-year mess.

Building a repeatable system so this never becomes a crisis

The 990-N itself is easy. The failure mode is almost always institutional memory, not the form. Treasurers rotate out, nobody documents the EIN or login, and three years disappear before anyone notices the org is gone from the IRS's exempt list. The fix is boring and effective: keep a single folder (physical or digital) with the EIN, the state charity registration number, login credentials for the IRS e-Postcard system, the last three years of 990-N confirmations, and a one-page calendar noting your fiscal year-end and 990-N due date. Hand that folder, more than the checkbook, to the next treasurer. If your organization also runs raffles, keep the state raffle license and renewal date in the same folder, since those deadlines are just as easy to lose track of. We built a State-Personalized Treasurer Kit at BoosterLedger for exactly this handoff gap: a one-time $99 packet that includes your state's specific filing and registration checklists so a new treasurer isn't starting from a blank page. It's not a substitute for talking to the IRS or your state charity office about your specific situation, but it's a decent starting checklist so nothing falls through the cracks during a leadership change.

Frequently asked questions

What is a 990-N used for?

The 990-N (e-Postcard) is the annual IRS filing that keeps a small tax-exempt organization's status active. It's for organizations with gross receipts normally $50,000 or less. It reports basic identifying information, not financial detail, and filing it prevents the automatic loss of tax-exempt status that hits after three consecutive missed years ^[1][3].

What does a treasurer do in a booster club or PTO?

A treasurer tracks all money coming in and going out, reconciles the bank account monthly, prepares reports for the board, files the annual 990-N or larger 990 form, and keeps records organized enough to hand off cleanly to the next treasurer. In small clubs, they're often the entire finance function.

Is Form 990 the same thing as Form 990-N?

No. Form 990 is the general name for the family of annual tax-exempt filings, which splits into 990-N (under $50,000 gross receipts), 990-EZ (under $200,000 and under $500,000 in assets), the full Form 990, and Form 990-PF for private foundations ^[1][2].

What happens if my club forgets to file 990-N for three years?

The IRS automatically revokes tax-exempt status after three consecutive years of missed 990-series filings, with no manual review required ^[3]. Revocation means donations stop being automatically tax-deductible and the organization may owe income tax. Reinstatement is possible but requires a new filing process.

Does filing 990-N cost anything?

No. Filing the 990-N e-Postcard itself is free through the IRS's online system. There's no filing fee, unlike applying for 501(c)(3) status (Form 1023 or 1023-EZ) or reinstating after revocation, both of which can carry an IRS user fee that changes periodically.

How do I know if my organization should file 990-N or 990-EZ?

Compare your organization's average gross receipts over the current year and prior two years to $50,000. Under that threshold, generally file 990-N. Between $50,000 and $200,000 in gross receipts (and under $500,000 in total assets), file 990-EZ instead ^[1][2]. Confirm the exact test in the current Form 990 instructions.

What is a treasurer, in one sentence?

A treasurer is the person responsible for tracking, safeguarding, and reporting an organization's money, including bank reconciliation, board reporting, and required government filings like the annual 990-N or 990.

Can I file 990-N late?

There's no penalty fee for a late 990-N filing and no extension request process, so if you're behind, just file it as soon as possible. The real risk isn't lateness on one year, it's three consecutive missed years, which triggers automatic revocation of tax-exempt status ^[3].

What information do I need to file the 990-N e-Postcard?

You need your organization's EIN, the tax year you're filing for, legal name and mailing address, any other names used, the name and address of a principal officer, your website if applicable, and confirmation that gross receipts are $50,000 or less and the organization hasn't terminated ^[1].

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

A club treasurer usually does every finance job alone, unpaid, on a rotating one- or two-year term: deposits, bookkeeping, reports, and IRS filings, with no staff support. That makes recordkeeping continuity across leadership changes the biggest practical risk for clubs, compared to corporate treasurers who have finance teams and permanent tenure.

How can I check if my nonprofit already lost its tax-exempt status?

Use the IRS Tax Exempt Organization Search tool at irs.gov, which shows current exempt status and includes a searchable list of organizations that lost status through automatic revocation ^[5]. Search by name or EIN; results appear immediately and the tool is free.

Do youth sports leagues and PTOs file the same 990-N as booster clubs?

Yes, if they're recognized tax-exempt organizations under the $50,000 gross receipts threshold, the filing requirement and process are identical regardless of whether the group is a booster club, PTO, or youth sports league. The form doesn't distinguish by activity type, only by size.
