TL;DR
Form 990-N, also called the e-Postcard, is the annual IRS filing for tax-exempt organizations with gross receipts of $50,000 or less. It's free, filed online at irs.gov, and takes about ten minutes once you have your EIN. Miss three years in a row and the IRS automatically revokes your tax-exempt status, no warning letter required.
What is Form 990 and how does the 990-N fit in?
Form 990 is the umbrella name for the IRS's annual information return for tax-exempt organizations. It's not a tax bill. Your booster club or PTO almost certainly doesn't owe income tax if it's recognized as exempt, but the IRS still wants an annual report showing the group is alive, active, and behaving like the nonprofit it claims to be. There are several versions depending on size. Form 990-N (the e-Postcard) is for the smallest organizations, those with gross receipts normally $50,000 or less [1]. Form 990-EZ is for organizations with gross receipts under $200,000 and total assets under $500,000. The full Form 990 is for anything bigger. Nearly every volunteer-run booster club, PTO, or youth sports league that's actually recognized as tax-exempt qualifies for the 990-N, which is the easy one. If you're trying to figure out which version applies to your group, see our breakdown on form 990 and the general [990](/articles/treasurer-basics/990) overview page.
What is a 990 tax form, exactly?
Despite the name, a 990 isn't really a "tax form" in the sense of calculating what you owe. It's an information return. The IRS created it so tax-exempt organizations, which don't pay federal income tax on program income, still have some public accountability. Donors, state charity regulators, and the IRS itself use these filings to check that an organization matches what it claimed when it applied for exemption. The 990-N specifically asks for almost nothing: your organization's legal name, EIN, tax year, address, name of a principal officer, and a confirmation that gross receipts are still $50,000 or under [1]. No financial statements, no program descriptions. That's the whole point of it, it exists so tiny all-volunteer groups don't need an accountant to stay compliant. Compare that to the 990-EZ or full 990, which do ask for a real balance sheet and income statement. If your booster club's revenue creeps past $50,000 (a big raffle year, a strong concession stand season, a one-time capital campaign), you'll need to step up to the 990-EZ instead. Our 990 tax form page walks through that threshold in more detail.
Who has to file the 990-N, and what counts as "gross receipts"?
Any organization recognized as tax-exempt under section 501(c) with gross receipts normally $50,000 or less must file the 990-N annually unless it chooses to file the 990-EZ or full 990 instead [1]. "Normally" matters here. The IRS looks at a rolling average, more than one year. For an organization in its first three years, it's the average of actual receipts over however many years it's existed. For an organization that's been around 3+ years, it's the average of the current year plus the prior two. Gross receipts means everything that came in the door before subtracting expenses: ticket sales, concession revenue, raffle ticket sales, membership dues, sponsorship checks, silent auction proceeds. It is not net profit. A booster club that grosses $60,000 from a big auction but only nets $15,000 after covering costs still counts the $60,000, and that pushes it over the $50,000 line, meaning 990-EZ territory, not 990-N. One wrinkle new treasurers trip on: this filing requirement is separate from being formally recognized as tax-exempt. Plenty of small booster clubs never filed Form 1023 or 1023-EZ to get IRS-recognized exemption in the first place, they just operate as an informal nonprofit or under a parent PTA/PTO umbrella. If your group was never granted 501(c)(3) or 501(c)(4) status, the 990-N filing requirement may not apply to you the same way, or you may be covered under a group exemption. Confirm your group's exemption status with the IRS before assuming you're on the hook (or off it).
How do I actually file the 990-N?
You file it online, directly through the IRS's e-Postcard filing system, linked from the IRS's page on annual electronic filing for small exempt organizations [2]. There's no paper option. You'll need an active IRS.gov account (the IRS moved 990-N filers to its Login.gov-based sign-in system in recent years), your organization's EIN, tax year end, legal name and address, and the name and address of one principal officer. The whole thing takes about ten minutes if you have that information handy. There's no fee. Compare that to the 990-EZ, which realistically needs a couple hours minimum and often outside help if your books aren't clean. A practical tip for incoming treasurers: before you touch the form, confirm your EIN and legal organization name exactly match IRS records. A surprising number of booster club filing headaches start because someone registered the group years ago under a slightly different name ("Lincoln HS Boosters" vs "Lincoln High School Athletic Booster Club Inc") and nobody since has matched that exactly. If the 990-N portal can't find your organization, that mismatch, or a lapsed/never-registered EIN, is usually why. Our irs form 990 page has a short checklist for verifying your org's IRS record before you file anything.
When is the 990-N due each year?
| December 31 | May 15 | |
|---|---|---|
| June 30 | November 15 | |
| August 31 | January 15 | |
| September 30 | February 15 | Mark the date on whatever calendar your board actually looks at, more than a mental note. Treasurer turnover is the number one reason small nonprofits miss this filing, the outgoing treasurer assumes the incoming one knows, and nobody files that year. |
The deadline is the 15th day of the 5th month after your organization's accounting period ends [1]. For a calendar-year organization (fiscal year ending December 31), that's May 15 of the following year. For a school-year-based booster club with a fiscal year ending June 30, the deadline is November 15. There's no extension form for the 990-N itself since there's nothing complex to prepare, but there's also effectively no penalty for filing it a few weeks late as a one-off. The real danger isn't lateness, it's total silence for three straight years, which triggers automatic revocation (more on that below). | Fiscal year end | 990-N due date |
What happens if I miss the 990-N filing deadline?
Missing one year isn't a crisis. Missing three years in a row is. 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-series return for three consecutive years [3]. There's no warning letter before this happens and no appeal process for the automatic revocation itself, it's a statutory trigger. The IRS publishes a searchable list of organizations that have lost exemption this way, called the Tax Exempt Organization Search or Auto-Revocation List [4]. If your booster club's name shows up there, your organization is no longer tax-exempt for federal purposes as of the revocation date, meaning donations made to it are no longer automatically tax-deductible for donors, and (depending on structure and state law) the organization may owe corporate income tax. Getting reinstated means filing Form 1023 or 1023-EZ again, sometimes with a reduced fee if you qualify for streamlined retroactive reinstatement within 15 months of revocation, per Revenue Procedure 2014-11 [5]. It is fixable. It is also a real hassle involving IRS user fees (currently $275 for the 1023-EZ or $600 for the full 1023, confirm current amounts on irs.gov since the IRS periodically adjusts these), back-filing catch-up returns, and weeks of waiting. Our 990n and form 990-n pages both cover the reinstatement process step by step if you're already in that spot.
What does a treasurer do, generally?
A treasurer manages an organization's money and makes sure required paperwork gets filed on time. For a booster club, PTO, or youth sports league, that means tracking every dollar in and out, reconciling the bank account monthly, presenting a clear financial picture to the board, and handling the annual IRS filing (usually the 990-N for small groups). Concretely, what does a treasurer do day to day? Deposit checks and cash promptly, ideally with a second person present for cash counts. Keep a simple ledger or use accounting software to categorize income (concessions, membership dues, sponsorships, raffle sales) and expenses (uniforms, equipment, tournament fees, insurance). Reconcile the bank statement every month against that ledger. Prepare a budget-to-actual report for board meetings. File the annual 990-N (or 990-EZ) by deadline. Keep receipts and documentation organized for at least three years, ideally seven, in case of an audit. What does a treasurer of a club do that's different from a corporate finance role? Mostly, it's simpler math but higher stakes for trust. Volunteer treasurers handle cash from bake sales and gate admissions, which is exactly the kind of loosely-controlled money that invites both honest mistakes and, occasionally, theft. A good treasurer builds simple controls: two signers on the bank account, a second person counting cash before deposit, receipts for reimbursements, and a habit of showing the numbers to the board regularly rather than once a year.
What is a treasurer, and what does a treasurer do in a club specifically?
A treasurer is the officer responsible for an organization's money and financial recordkeeping. In a school booster club, PTO, or league, the treasurer is usually an elected or appointed volunteer position, often serving a one- or two-year term, and typically works alongside a president, secretary, and sometimes a separate bookkeeper. What does a treasurer do in a club setting, task by task? Collect and deposit dues, ticket sales, and fundraiser proceeds. Pay approved bills and reimbursements, usually requiring receipts and often a second signature above some dollar threshold set by the bylaws. Maintain the checkbook or accounting software. Report income and expenses at every board meeting, more than annually. Prepare or oversee the annual budget. File the 990-N (or appropriate 990 variant) each year. Keep tax-exempt determination letters, EIN documentation, bylaws, and insurance policies organized and handed off cleanly to the next treasurer. What do treasurers do that a president or secretary doesn't? The line is usually clean: the secretary handles meeting minutes and correspondence, the president handles overall direction and represents the group publicly, and the treasurer is the only one who should be able to say, with a straight face and current numbers, exactly how much money the organization has and where it went. If your club's bylaws don't spell out signature limits, reimbursement rules, or who reconciles the bank statement, that's a gap worth fixing before, not after, a new treasurer takes over. That's part of why we built the $99 one-time State-Personalized Treasurer Kit, which bundles state-specific filing checklists, handoff templates, and a starter chart of accounts so a new volunteer treasurer isn't reconstructing all of this from scratch.
What's the difference between 990-N, 990-EZ, and the full Form 990?
| 990-N (e-Postcard) | Gross receipts normally ≤ $50,000 [1] | Name, EIN, address, principal officer, tax year, confirmation of receipts threshold | |
|---|---|---|---|
| 990-EZ | Gross receipts < $200,000 AND total assets < $500,000 [1] | Summary income statement, balance sheet, program descriptions, some compensation disclosure | |
| Form 990 (full) | Gross receipts ≥ $200,000 OR total assets ≥ $500,000 [1] | Full financial statements, governance questions, detailed program service accomplishments, compensation, schedules | A booster club can technically choose to file the 990-EZ or full 990 even if it qualifies for the 990-N, some do this voluntarily because a grantor or school district wants to see actual financial statements. But there's no requirement to do that, and for most all-volunteer groups it's extra work without extra benefit. Stick with the 990-N if you legitimately qualify. For side-by-side detail on moving between these thresholds as your organization grows, see our 990 tax form breakdown. |
The three main versions scale with organization size, and picking the wrong one either wastes your time or gets you flagged for filing incorrectly. | Form | Who files it | What it requires |
Does the 990-N apply to PTOs, booster clubs, and youth sports leagues the same way?
Mostly yes, with one important caveat about group exemptions. If your PTO, booster club, or league applied for and received its own separate 501(c)(3) or 501(c)(4) determination letter from the IRS, it files its own 990-N (assuming it's under the $50,000 gross receipts threshold) using its own EIN. But some PTOs operate under a state or national PTA's group exemption, meaning the parent organization's determination letter covers the local unit, and filing may be handled differently, sometimes centrally by the state PTA, sometimes still required individually. Some youth sports leagues are chartered under a national umbrella (certain leagues under national governing bodies) with similar group exemption arrangements. If you're not sure whether your organization has its own EIN and files independently, or is covered under a parent group's umbrella, check your organization's own paperwork first (look for a determination letter with your specific organization's name on it) and confirm with the IRS Tax Exempt Organization Search tool [4] or by calling the IRS Exempt Organizations customer account services line. This is one of the most common points of confusion for incoming treasurers, and getting it wrong in either direction, filing separately when you shouldn't need to, or assuming you're covered when you're not, both cause problems down the line.
What records do I need before I sit down to file?
Gather these before you start, it'll take the ten-minute filing down to five: your organization's legal name exactly as the IRS has it on file, your EIN, your fiscal year start and end dates, the mailing address, and the name and address of one current principal officer (usually the president or treasurer). You don't need financial statements to file the 990-N itself, since the form doesn't ask for numbers beyond confirming you're under $50,000. But you should still know your actual gross receipts figure, because if it turns out you crossed $50,000 this year, you need to file the 990-EZ instead, not the 990-N, and finding that out after you've already submitted the wrong form creates cleanup work. Keep a simple annual habit: as soon as your fiscal year closes, total up gross receipts before you do anything else. That one number tells you which form applies. Write it down in your handoff binder for whoever takes over the treasurer role next.
Frequently asked questions
What is Form 990-N?
Form 990-N, nicknamed the e-Postcard, is the simplest annual IRS filing for tax-exempt organizations with gross receipts normally $50,000 or less. It's filed online for free at irs.gov and asks only for basic identifying information, no financial statements required.
What is a 990 tax form used for?
A 990-series form is an annual information return, not a tax bill. It lets the IRS and the public confirm a tax-exempt organization is still operating within the terms of its exemption. Which version you file (990-N, 990-EZ, or full 990) depends on gross receipts and total assets.
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, reports finances to the board, and files the annual IRS return (usually the 990-N). Good treasurers also set basic controls like two signers on the account and receipts for every reimbursement.
How much does it cost to file Form 990-N?
Nothing. The 990-N is free to file through the IRS's online e-Postcard system. There's no user fee, unlike Form 1023 applications for exemption, which currently run $275 (1023-EZ) or $600 (full 1023); confirm current fees on irs.gov since they change periodically.
What happens if my booster club never filed a 990-N?
One missed year usually isn't fatal. But federal law requires automatic revocation of tax-exempt status after three consecutive years of not filing any required 990-series return. Check the IRS Tax Exempt Organization Search tool to see if your organization already appears on the auto-revocation list.
Can I file the 990-N late?
Yes, there's no penalty fee for filing the 990-N late as a single occurrence, and no extension request is needed since the form is so minimal. The real risk is cumulative: three consecutive years of non-filing triggers automatic loss of tax-exempt status under federal law.
What's the difference between 990-N and 990-EZ?
The 990-N is for organizations with gross receipts normally $50,000 or less and requires only basic contact information. The 990-EZ is for organizations under $200,000 in gross receipts and under $500,000 in total assets, and requires actual financial statements and program details.
Does a small PTO or booster club need to file taxes?
If your PTO or booster club has its own IRS tax-exempt determination, it doesn't owe federal income tax on typical program revenue, but it still must file an annual information return, usually the 990-N if gross receipts stay at or under $50,000. Confirm your specific exemption status with the IRS.
What is a treasurer, exactly, in a nonprofit or club context?
A treasurer is the elected or appointed officer responsible for an organization's finances: collecting and depositing money, paying bills, keeping records, reporting to the board, and handling required tax filings like the 990-N. It's usually a volunteer role in booster clubs, PTOs, and youth sports leagues.
How do I know if my organization qualifies for the 990-N instead of 990-EZ?
Add up your organization's total gross receipts (all money in, before expenses) for the current year averaged with the prior two years. If that average is $50,000 or less, you qualify for the 990-N. If it's higher, you need the 990-EZ or full Form 990 instead.
What is the IRS auto-revocation list?
It's a public, searchable IRS database (part of Tax Exempt Organization Search) listing every organization that automatically lost tax-exempt status for failing to file required 990-series returns for three consecutive years. Anyone can check it by organization name or EIN at irs.gov.
Can I get my nonprofit's tax-exempt status back after auto-revocation?
Usually yes, through reinstatement by filing Form 1023 or 1023-EZ again. Organizations that apply within 15 months of revocation may qualify for streamlined retroactive reinstatement under Revenue Procedure 2014-11. It takes real paperwork and IRS processing time, but it's a well-worn path, not a dead end.
