TL;DR
Form 990-N (the e-Postcard) is the IRS's free, 8-question online filing for tax-exempt organizations with gross receipts normally $50,000 or less. It's due by the 15th day of the 5th month after your fiscal year ends. Miss three years in a row and the IRS automatically revokes your tax-exempt status.
What is Form 990 and how does 990-N fit in?
Form 990 is the annual information return the IRS requires from most tax-exempt organizations, the nonprofit version of a tax return even though most filers owe no tax. It tells the IRS (and the public, since these are open records) what money came in, what went out, and roughly how the organization is run [1]. There isn't just one 990. The IRS runs a tiered system based on gross receipts and assets, and your booster club or PTO almost certainly lands on the smallest tier. Form 990-N, nicknamed the "e-Postcard," is that smallest option: a short online form for organizations whose gross receipts are normally $50,000 or less [2]. Above that threshold, groups step up to Form 990-EZ (gross receipts under $200,000 and total assets under $500,000) or the full Form 990 for anything bigger [3]. If you're not sure which one applies to your group this year, check your last three years of gross receipts first; "normally" means the IRS looks at an average, more than the current year [2].
What is a 990 tax form, exactly, and why do booster clubs and PTOs have to file one?
A 990 tax form isn't an income tax return in the usual sense. Most booster clubs, PTOs, and youth sports groups hold 501(c)(3) status, which exempts them from federal income tax, but exempt from tax does not mean exempt from filing. Congress requires almost every tax-exempt organization to file some version of the 990 every year to keep that exemption alive [4]. The filing requirement exists because tax exemption is a public benefit, donations can be tax-deductible, the org pays no federal income tax, and in exchange the IRS (and anyone else, since 990s are public) gets to see the money trail. Skip it and the IRS treats your organization as if it stopped operating as an exempt entity, even if your teams are still practicing every Tuesday night. The practical trap for volunteer treasurers: this obligation transfers with the job, and it doesn't pause because nobody remembers the login. A group's exempt status can get auto-revoked over a filing nobody knew was due, sometimes years after the fact.
What does a treasurer do, and where does 990-N fit into the job?
A treasurer's core job is keeping the organization's money straight: tracking what comes in, what goes out, reconciling the bank account, and making sure the group's tax and state filings happen on time. Filing the 990-N (or 990-EZ, or full 990) is one of the treasurer's yearly, non-negotiable deadlines, not an optional extra. What does a club treasurer do day to day? Collect dues and fundraising cash, pay vendors and refs, keep receipts, hand off clean books to the next officer. What does a treasurer of a club do at the calendar-level? Track the fiscal year end, file the 990-series return within 5.5 months of that date, renew any state charitable registration, and keep the state raffle license current if the group runs raffles. What do treasurers do that nobody sees until it's missed? They're the one person tracking the EIN, the online 990-N login, and the exact date the fiscal year closes. If that person leaves without documenting any of it, the next treasurer often has no idea a filing is even due, which is exactly how three years slip by and revocation happens.
Who qualifies to file the 990-N e-Postcard instead of a longer 990?
You can file 990-N if your organization's gross receipts are normally $50,000 or less [2]. "Normally" is a rolling average: the IRS looks at the average over the current year plus the two prior years (for orgs in existence three years or more), or a scaled average for newer organizations [2]. Some organizations can't use 990-N even under that threshold. Private foundations must file Form 990-PF regardless of size, and section 509(a)(3) supporting organizations have their own rules [2]. For a typical booster club or PTO running concessions, spirit wear, and a few fundraisers, 990-N is usually the right box, but check your specific receipts history before assuming. If your group crossed $50,000 in gross receipts this year but has been under it historically, you likely still qualify based on the rolling average. If you're consistently over $50,000 but under $200,000 in receipts and under $500,000 in assets, you're in Form 990-EZ territory instead [3].
How do you actually file the 990-N e-Postcard?
Form 990-N is filed entirely online through the IRS website; there's no paper version [5]. As of the current IRS system, filers use the Form 990-N Electronic Filing System at IRS.gov, which requires an active login.gov or ID.me account to access [5]. You'll need eight pieces of information: your organization's EIN, tax year, legal name and mailing address, any other names the org uses, the name and address of a principal officer, your website (if you have one), confirmation that gross receipts are normally $50,000 or less, and a statement if the organization has terminated or is going out of business [5][6]. There's no fee to file 990-N [5]. Most treasurers can complete it in under 15 minutes once they have the EIN and prior year's info in hand. If you're the new treasurer and don't know the org's EIN, check old bank statements, the state charity registration, or prior board minutes; the IRS won't assign a new one just because leadership changed. If your group has never filed anything with the IRS since incorporating, or you genuinely can't find any 990 history for your organization, confirm with the IRS and your state charity office before assuming 990-N is even the right form; some brand-new groups need to establish exempt status first.
When is the 990-N due, and what if you miss the deadline?
The 990-N is due by the 15th day of the 5th month after the end of your organization's fiscal year [2]. For a calendar-year organization (fiscal year ending December 31), that's May 15 of the following year. Unlike some tax forms, there's no extension available for 990-N and, notably, no late penalty for filing it late in a given year [2]. That sounds forgiving, and for a single missed year it is. The real danger is cumulative: file late or not at all for three consecutive years, and the IRS automatically revokes your tax-exempt status on the filing due date of that third year, by law, with no warning letter required first . That automatic revocation rule comes straight from the Pension Protection Act of 2006, codified at Internal Revenue Code section 6033(j): "failure to file... for three consecutive years" results in revocation "as of the date set by the Secretary for the filing of the third annual return" . It's mechanical. The IRS doesn't evaluate intent or excuses; the computer flips the status.
What happens if your organization's tax-exempt status gets auto-revoked?
Once revoked, your organization loses its federal tax exemption, meaning it may owe income tax on revenue going forward, and donors can no longer treat gifts to it as tax-deductible . The IRS publishes revoked organizations on its Tax Exempt Organization Search / Auto-Revocation List, which is public and searchable . Many small groups don't find out until a bank asks for exempt-status documentation, a grant application gets rejected, or a parent asks for a donation receipt and the tax preparer flags it. By then it may have been revoked for a year or more. The fix is Form 1023 (or the streamlined Form 1023-EZ for eligible small organizations) to apply for reinstatement, plus filing any past-due 990s. The IRS offers streamlined retroactive reinstatement procedures for organizations that were eligible to file 990-N or 990-EZ and apply within 15 months of revocation; check current IRS guidance for exact eligibility and any user fee, since these details are updated periodically . This isn't a quick fix and it isn't free; budget real time and possibly professional help for it. Confirm current procedures and fees with the IRS before assuming any specific path applies to your organization.
What is the difference between 990-N, 990-EZ, and the full 990?
| Form | Who files it | Gross receipts threshold | Filing method | Cost to file | |
|---|---|---|---|---|---|
| 990-N | Smallest exempt orgs | Normally $50,000 or less [2] | Online only, 8 questions [5] | Free [5] | |
| 990-EZ | Mid-size exempt orgs | Under $200,000 receipts, under $500,000 assets [3] | Electronic filing required [3] | Free to file, may need paid preparer | |
| 990 (full) | Larger exempt orgs | $200,000+ receipts or $500,000+ assets [3] | Electronic filing required [3] | Free to file, usually needs a preparer | Most booster clubs and PTOs stay in 990-N or 990-EZ territory for years. If your group just had a breakout fundraising year (a big gala, a major capital campaign) check whether you crossed into 990-EZ range before defaulting to the e-Postcard out of habit. The 990 tax form system is graduated on purpose, and filing the wrong tier isn't just an inconvenience, since a full 990 requires far more disclosure than an e-Postcard. |
What does a PTO or booster club treasurer need to track for 990-N, beyond just filing?
Filing the form itself takes minutes. Staying ready to file, every year, without drama, is the actual job. A few things a treasurer should have on hand before the deadline: the organization's EIN, the exact fiscal year end date, a login.gov or ID.me account tied to the filer, and a rough gross receipts total from the bank records. Hand-off matters here more than almost anywhere else in the treasurer role. If the outgoing treasurer doesn't pass along the EIN, the fiscal year end, and confirmation of the last filed year, the incoming treasurer is starting blind, which is exactly the scenario that leads to three missed years and auto-revocation. This is also where a written transition checklist earns its keep: EIN, state charity registration number, raffle license status, bank signers, and the date and confirmation number of the last 990-N filed. A state-personalized treasurer kit ($99 one-time) builds that handoff packet for you so the next volunteer isn't reconstructing three years of history from a shoebox of receipts.
Does filing 990-N replace state charity registration or a raffle license?
No. Form 990-N only satisfies the federal IRS filing requirement. Most states run a separate charitable solicitation registration process, and if your group runs raffles, that typically needs its own state gaming or attorney general license on top of everything else. Some states also require a copy of your 990 or 990-N confirmation as part of their charity registration renewal, so filing federal first can actually be a prerequisite for staying compliant at the state level. Requirements vary by state and change over time, so confirm current rules with your state charity office or attorney general before assuming last year's process still applies. A treasurer juggling all three (IRS filing, state charity registration, state raffle license) is normal for active booster and PTO groups. Track each on its own line with its own deadline; they don't share a calendar even though they often get lumped together in people's heads as "the compliance stuff."
Frequently asked questions
What is Form 990?
Form 990 is the annual information return the IRS requires from most tax-exempt organizations, reporting income, expenses, and governance details. It comes in tiers based on size: the full Form 990, the shorter Form 990-EZ, and the free 8-question Form 990-N for organizations with gross receipts normally $50,000 or less.
What is the 990-N and who has to file it?
The 990-N, called the e-Postcard, is a free online IRS filing for tax-exempt organizations with gross receipts normally $50,000 or less. It requires eight basic pieces of information and no financial detail. Private foundations and certain supporting organizations can't use it even if small; check IRS guidance for exclusions.
What does a treasurer do for a booster club or PTO?
A treasurer tracks money in and out, reconciles the bank account, files required tax and state paperwork (like Form 990-N), keeps records for the next officer, and flags problems to the board early. The role blends bookkeeping with compliance calendar management, since deadlines like the IRS 990 filing don't move for volunteer turnover.
What happens if you miss the 990-N deadline one year?
Nothing immediate. There's no late fee for a single missed 990-N filing, per IRS guidance. The real risk is cumulative: three consecutive missed years triggers automatic revocation of tax-exempt status under Internal Revenue Code section 6033(j), with no advance warning from the IRS.
How do I know if my organization qualifies for the 990-N instead of 990-EZ?
You qualify for 990-N if your gross receipts are normally $50,000 or less, averaged over the current and prior two years. If receipts run higher but stay under $200,000 (and assets under $500,000), you'd file Form 990-EZ instead. Check your last three years of bank records to confirm which tier fits.
Is there a fee to file Form 990-N?
No. Filing Form 990-N through the IRS's online e-Postcard system is free. If your organization's status has already been auto-revoked and you need to apply for reinstatement using Form 1023 or 1023-EZ, that process does carry a user fee; confirm the current amount directly with the IRS.
What happens if our tax-exempt status gets auto-revoked?
The organization loses federal tax exemption, donations stop being tax-deductible, and the group appears on the IRS's public Auto-Revocation List. Reinstatement requires filing Form 1023 or 1023-EZ plus any past-due 990s. Streamlined retroactive reinstatement is available for some small organizations that apply within 15 months of revocation; confirm current eligibility with the IRS.
Can a new treasurer file 990-N without accountant help?
Usually yes. The form only asks for eight basic items (EIN, tax year, legal name, address, principal officer, website, receipts confirmation, and termination status) and files free online in minutes. Complications arise mainly when the EIN is unknown, prior years were missed, or the organization may have already been auto-revoked.
What is a 990 tax form used for if nonprofits don't pay income tax?
It's an information return, not a tax bill. The IRS and the public use it to see how a tax-exempt organization raises and spends money, who runs it, and whether it still meets the terms of its exemption. Filing it is the condition attached to keeping tax-exempt status, not a payment obligation.
Where do I find my organization's EIN if the outgoing treasurer didn't leave it?
Check old bank statements, prior state charity registration filings, past grant applications, or old 990 filings on the IRS Tax Exempt Organization Search tool. The IRS won't issue a new EIN just because officers changed; the number stays with the organization for its entire existence.
Does filing Form 990-N satisfy state charitable registration requirements too?
No, they're separate systems. Form 990-N only meets the federal IRS requirement. Most states run their own charitable solicitation registration, and some ask for a copy of your federal 990 filing as part of that state renewal. Confirm requirements with your state charity office or attorney general directly.
What does a club treasurer do besides taxes and filings?
Day to day, a club treasurer collects dues and fundraising money, pays vendors and officials, reconciles accounts, prepares budget updates for the board, and keeps receipts organized. Around deadlines, that same person handles the IRS 990 filing, any state charity renewal, and raffle license upkeep if the group runs raffles.
