990-N explained: what booster treasurers must file

Last updated 2026-07-24

What is Form 990?

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 most cases (exempt orgs generally don't owe income tax on mission-related revenue), it's a disclosure document. The IRS uses it to confirm you're still operating within your exempt purpose, and the public (donors, watchdog sites, journalists) can pull it to see how a nonprofit spends money. There isn't just one "990." There's a family of forms sized to the organization: the full Form 990, the shorter Form 990-EZ, and the Form 990-N for the smallest groups. Which one you file depends entirely on your gross receipts and total assets, not on how much paperwork you feel like doing. Booster clubs, PTOs, and youth sports leagues almost always fall into the smallest tier. ^[1] If you're building out a full understanding of the filing family, the general form 990 overview and the 990 tax form basics page cover the EZ and full versions in more depth.

What is a 990-N (the e-Postcard)?

Form 990-N, officially the "Electronic Notice (e-Postcard) for Tax-Exempt Organizations Not Required to File Form 990 or 990-EZ," is the smallest version of the annual filing. The IRS built it for small nonprofits so they wouldn't need an accountant just to check a box saying "we're still here." It asks for about eight items: your organization's legal name and any doing-business-as name, mailing address, website (if you have one), Employer Identification Number (EIN), the name and address of a principal officer, your tax year, confirmation that annual gross receipts are normally $50,000 or less, and a statement if you've terminated or gone out of business. ^[2] There's no financial detail beyond that gross receipts confirmation. No balance sheet, no program expense breakdown, no line items. That's the whole point: it's a postcard, not an audit.

Who has to file Form 990-N?

Most tax-exempt organizations with gross receipts normally $50,000 or less must file the 990-N annually, unless they choose to file the full 990 or 990-EZ voluntarily. "Normally" is an IRS term of art: it means the average of your gross receipts over the current year and the two prior years (or a shorter formula for organizations under three years old). ^[2] A few groups are exempt from the annual filing requirement altogether, including churches and their integrated auxiliaries, and organizations included in a group return. Private foundations file a different form (990-PF) regardless of size. ^[1] For a typical PTO, booster club, or youth sports league running bake sales, concession stands, and small fundraisers, the $50,000 gross receipts threshold covers almost everyone in year one or two. Once you cross that average, you move up to the 990-EZ or full 990 and the filing gets a lot more involved.

How do you file the 990-N e-Postcard?

You file Form 990-N entirely online at the IRS website, there's no paper option and no mailing address to send it to. The filing system runs through IRS.gov under the same page that covers annual electronic filing requirements for small exempt organizations. ^[2] Before you start, you need your organization's EIN, tax year end date, legal name and address exactly as registered with the IRS, and the name and address of a principal officer. First-time filers sometimes get tripped up because the system requires your organization's name to match IRS records precisely, so pull up your CP575 EIN confirmation letter if you have it. The filing itself takes most treasurers under ten minutes once you have the EIN and officer info in hand. There's no fee. If your organization changed its accounting period, or if you're filing for a short year because of a fiscal year change, note that on the form; the system walks you through it.

When is the 990-N due?

Form 990-N is due by the 15th day of the 5th month after the end of your organization's fiscal year. A booster club running on a calendar year (January to December) has a May 15 deadline. A school-year based booster club or PTO (July to June) has a November 15 deadline. ^[2] Unlike income tax returns, there's no extension available for the 990-N and technically no penalty for filing late, since it's an information notice rather than a return with a dollar figure attached. But don't read that as "it doesn't matter." The real consequence isn't a late fee, it's accumulation: miss it enough years in a row and you lose your exempt status entirely, which is a much bigger problem than any penalty would have been.

What happens if you don't file the 990-N (auto-revocation)?

This is the part that catches new treasurers off guard. Federal law (added by the Pension Protection Act of 2006, codified at 26 U.S.C. § 6033(j)) requires the IRS to automatically revoke the tax-exempt status of any organization that fails to file its required 990-series return (including the 990-N) for three consecutive years. ^[3] The IRS states it plainly: "Organizations that do not file for three consecutive years automatically lose their tax-exempt status. The revocation of an organization's tax-exempt status does not take place until the filing due date of the third year." ^[4] There's no warning letter that says "final notice," and by the time you notice, it's often already happened. The IRS publishes a searchable Auto-Revocation List so you can check your own organization's status directly. ^[5] Once revoked, your organization owes income tax on revenue going forward, donors' contributions are no longer tax-deductible, and depending on your state, you may also lose state tax exemptions or charitable registration standing tied to federal status. For a booster club running concession stands and gate fundraisers, that can mean an unexpected tax bill on money you thought was exempt. Recovering from auto-revocation means filing Form 1023 or 1023-EZ for reinstatement, and depending on how long you've been revoked, possibly filing back 990s too. It's a real project, not a quick fix, and it usually needs someone who's done it before. If your booster club shows up on that IRS revocation list, treat it as priority one, not a someday task. ^[6]

990-N vs 990-EZ vs full 990: what's the difference?

990-N (e-Postcard)	Smallest orgs	Normally $50,000 or less	No limit specified	~8 basic items, no financials
990-EZ	Mid-size orgs	Less than $200,000	Less than $500,000	Summary financials, program info
Form 990 (full)	Larger orgs	$200,000 or more	$500,000 or more	Full financial statements, governance detail	An organization under the 990-N threshold can always choose to file the 990-EZ or full 990 voluntarily instead. Some treasurers do this because a lender, grant funder, or school district wants to see actual financial detail, more than a postcard confirming existence. That's a legitimate reason to file up a level even when you don't have to. For comparisons across all three, the 990n and irs form 990 reference pages break down the EZ schedules and full-form sections in detail.

The three forms scale with your organization's size, measured by gross receipts and total assets. Here's the breakdown that determines which one applies to you: ^[1] | Form | Who files it | Gross receipts | Total assets | Detail required |

What is a treasurer? What does a treasurer do?

A treasurer is the person responsible for an organization's money: tracking what comes in, what goes out, and making sure both are documented well enough that someone else could pick up the books and understand them. In a booster club, PTO, or youth sports league, the treasurer is usually a volunteer parent, not a trained accountant, and that's fine. The job is about consistency and paper trails, not expertise. Core treasurer duties typically include: keeping a running ledger of income and expenses, reconciling the bank statement monthly, collecting and organizing receipts, preparing a budget or financial report for board meetings, managing deposits from fundraisers and concessions, and filing the organization's annual IRS return (usually the 990-N for small groups). Many treasurers also handle reimbursement requests, signing authority on the bank account, and coordinating with whoever prepares tax filings if the group is large enough to need help. The treasurer isn't usually the person who decides how money gets spent, that's the board's job, but the treasurer is the one who makes sure spending decisions actually get recorded correctly and match what was approved.

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

A club or booster treasurer operates at a much smaller scale than a corporate treasurer, but the fundamentals are the same: track money, report it honestly, keep records. Where it differs is in structure. Corporate treasurers work with finance teams, professional auditors, and dedicated accounting software. A club treasurer for a youth sports league or PTO is often one volunteer with a shoebox of receipts and a shared spreadsheet, working an hour or two a week between a day job and their kid's practice schedule. That means club treasurer duties lean heavily on simplicity and handoff-readiness. You want records simple enough that next year's volunteer (who may have zero financial background) can take over without a training course. Practical tasks for a club treasurer include: - Opening and maintaining the bank account (and knowing who has signing authority)

• Depositing fundraiser and concession cash promptly, with a count sheet signed by two people
• Tracking every expense with a receipt, even small reimbursements
• Filing the annual 990-N (or higher form, if the club has grown past the threshold)
• Handling any state charitable raffle registration paperwork if the club runs raffles
• Producing a simple year-end report for the outgoing/incoming board The stakes are real even at small scale. A booster club that skips the 990-N for three straight years faces the same auto-revocation consequence as a much larger nonprofit. Size doesn't earn you a pass from the IRS filing requirement.

Do PTOs and booster clubs need to be tax-exempt to file a 990-N?

Yes, only organizations recognized as tax-exempt by the IRS (or that have applied for and are operating under exempt status) file the 990-series returns, including the 990-N. If your booster club or PTO has never applied for tax-exempt status and doesn't have a determination letter, you likely need to sort that out first, typically through Form 1023-EZ for smaller organizations, before the annual 990-N filing requirement even applies to you. ^[7] Some booster clubs operate for years as unofficial extensions of a school without ever incorporating or applying for exempt status. That's a common setup, but it comes with real limits: no separate legal liability protection, no ability to accept tax-deductible donations directly, and no 990-N to file because there's no exempt status to maintain in the first place. If your group is collecting significant money (concessions, sponsorships, raffle proceeds) it's worth confirming with the IRS and a knowledgeable local resource whether formal incorporation and exemption make sense.

How do you check if your organization already lost its exempt status?

The IRS maintains a public, searchable Tax Exempt Organization Search tool, which includes the Auto-Revocation List showing organizations that lost exempt status for failing to file for three consecutive years. ^[5] Search your organization's name or EIN directly; if you're on the list, the search result will show the revocation date. This is worth checking the moment you take over as a new treasurer, before you do anything else. It's a five-minute search that can save you from months of confusion later. If you inherit a checkbook, a shoebox of receipts, and zero paper trail from the last treasurer, checking the revocation list should be step one, right alongside confirming who has signing authority on the bank account. This is exactly the kind of gap a State-Personalized Treasurer Kit is built to catch early: a $99 one-time kit that walks a new volunteer treasurer through the filings and deadlines specific to their state, so a missed 990-N doesn't sit unnoticed for three years running.

What records do you need before filing a 990-N?

Because the 990-N doesn't require financial detail, you technically don't need a full set of books just to submit it. But you do need to know your gross receipts are actually under the $50,000 average threshold, and that requires basic recordkeeping regardless. Before filing, confirm you have: your EIN (find it on the original IRS determination letter or a past filing, don't guess), your fiscal year dates, the current principal officer's name and mailing address, and a rough gross receipts total for the current and prior two years to confirm you're under threshold. If you're not certain your gross receipts qualify you for the 990-N versus the 990-EZ, run the actual numbers rather than assuming, because filing the wrong form (or filing 990-N when you should've filed 990-EZ) can create its own compliance headache down the line. Keep a copy of every year's filing confirmation. The IRS system generates a confirmation once you submit; save it in whatever handoff binder or shared drive your organization keeps for the next treasurer.

Frequently asked questions

What is Form 990-N used for?

Form 990-N (the e-Postcard) lets small tax-exempt organizations, those with gross receipts normally $50,000 or less, satisfy their annual IRS filing requirement with a short online submission instead of a full financial return. It confirms the organization still exists and operates within its exempt purpose. There's no fee and no financial detail required beyond the gross receipts confirmation itself.

What is a 990 tax form?

A 990 tax form is the annual information return tax-exempt organizations file with the IRS to report income, spending, and activities to maintain public accountability. It comes in three sizes based on gross receipts and assets: the full Form 990, the mid-size Form 990-EZ, and the smallest Form 990-N. It's a disclosure document, not typically a tax bill.

Who is required to file Form 990-N?

Tax-exempt organizations with gross receipts normally $50,000 or less must file the 990-N annually unless they're a church, an integrated auxiliary of a church, included in a group return, or choose to file the fuller 990-EZ or 990 voluntarily. Private foundations file Form 990-PF instead, regardless of size. Confirm your specific status with the IRS if you're unsure which category applies.

When is the 990-N due each year?

Form 990-N is due by the 15th day of the 5th month after your organization's fiscal year ends. Calendar-year organizations (January to December) file by May 15. School-year organizations (July to June) file by November 15. There's no extension option, so mark the date on the same calendar as your other annual filings.

What happens if a booster club doesn't file the 990-N for three years?

The IRS automatically revokes tax-exempt status when a required 990-series return, including the 990-N, goes unfiled for three consecutive years, per federal law from the Pension Protection Act of 2006. There's no separate warning letter. Once revoked, the organization owes income tax on revenue and donations stop being tax-deductible until reinstatement is filed and approved.

How do I know if my organization lost its tax-exempt status?

Search the IRS Tax Exempt Organization Search tool, which includes a public Auto-Revocation List, by your organization's name or EIN. If your group appears on that list, the tool will show the revocation date. Check this the moment you take over as a new treasurer, since gaps in filing history are common when records get handed off informally.

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

A club treasurer tracks income and expenses, reconciles the bank account monthly, keeps receipts organized, prepares financial reports for board meetings, manages fundraiser deposits, and files the organization's annual IRS return, usually Form 990-N for small groups. The role is about consistent recordkeeping and transparency, not financial expertise or spending authority.

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

The three forms scale with organization size. Form 990-N applies when gross receipts are normally $50,000 or less and requires only about eight basic items, no financial detail. Form 990-EZ applies under $200,000 in gross receipts and under $500,000 in assets, requiring summary financials. The full Form 990 applies above those thresholds and requires complete financial statements.

Can a small nonprofit choose to file a full 990 instead of the 990-N?

Yes. Any organization eligible for the 990-N can voluntarily file the 990-EZ or full Form 990 instead. Some treasurers do this when a bank, grant funder, or school district wants to see actual financial statements rather than a bare confirmation of existence. There's no penalty for filing a more detailed form than required.

Does filing the 990-N cost anything?

No. Form 990-N is free to file through the IRS's online e-Postcard system. There is no paper filing option and no processing fee. Be cautious of third-party websites that charge a fee to "help" file the 990-N since the official IRS system requires no payment at all.

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

You need your organization's legal name and any doing-business-as name, current mailing address, website if applicable, EIN, the name and address of a principal officer, your tax year, and confirmation that gross receipts normally run $50,000 or less. Pull the EIN from your original IRS determination letter if you're unsure of it.

What does a treasurer of a club do if there's no exempt status yet?

If a club or PTO has never applied for tax-exempt status, the 990-N filing requirement doesn't apply because there's no exempt status to maintain. The treasurer's first task in that situation is confirming with the IRS whether the group should formally incorporate and apply for exemption, often through Form 1023-EZ for smaller organizations, before taking on annual filing duties.
