TL;DR
You file Form 990-N (the e-Postcard) free through the IRS's e-file system at irs.gov, not through mailed paperwork. It's for tax-exempt organizations with gross receipts normally $50,000 or less. The filing takes about 8 questions and a few minutes. Miss it three years running and the IRS automatically revokes your tax-exempt status.[1]
How do I file Form 990-N online?
You go to the IRS's Form 990-N (e-Postcard) filing site, which as of 2016 runs through IRS.gov directly rather than the old third-party Urban Institute portal. You'll need your organization's EIN, legal name and any doing-business-as name, mailing address, the name and address of a principal officer, your tax year, confirmation your gross receipts are normally $50,000 or less, and a statement about whether the organization is still in business.[1] There's no login required in the traditional sense. The IRS system asks you to enter your EIN, and if it recognizes your organization, it pulls up basic identifying info you confirm or update. The whole thing genuinely takes most treasurers under 15 minutes once they have the EIN and financial summary in hand. You cannot file 990-N by mail. It exists only as an electronic form, which is part of why groups miss it: there's no paper reminder in a file folder, no physical form sitting on a desk. If your organization's gross receipts run above the $50,000 threshold, you don't qualify for the e-Postcard and need Form 990-EZ or Form 990 instead, filed on different schedules with actual financial detail.[1] If this is your first time touching the books, it helps to read up on form 990 and how the different versions (N, EZ, full 990) split by revenue size before you start guessing which one applies to you.
What is Form 990, and how is 990-N different from the full 990?
| 990-N (e-Postcard) | Smallest orgs | Normally $50,000 or less | |
|---|---|---|---|
| 990-EZ | Mid-size orgs | Less than $200,000 and total assets under $500,000 | |
| 990 (full) | Larger orgs | $200,000 or more, or assets $500,000 or more | |
| 990-PF | Private foundations | Any size, different form entirely | These thresholds come straight from the IRS's own filing thresholds page.[3] A booster club running mostly bake sales and concession stands almost always lands in the 990-N bucket. A PTO that just built a $60,000 playground fund might tip into 990-EZ territory for that year, then drop back down. You check the threshold every single year, not once. If you want the fuller comparison of what goes on each version and why the IRS designed it this way, 990 tax form and irs form 990 both break down the line-by-line differences. |
Form 990 is the annual information return that tax-exempt organizations file with the IRS to report income, expenses, activities, and governance. It's not a tax bill in most cases (exempt orgs generally don't owe income tax), it's a disclosure document the IRS and the public use to see what the organization did with its money.[2] The IRS actually has four versions depending on size, and this trips up a lot of new booster club treasurers: | Form | Who files it | Gross receipts threshold |
What is a 990 tax form, in plain language?
Think of it as a report card, not a tax return in the traditional sense. Most 501(c)(3) organizations don't pay federal income tax on the money they raise for their mission, but the IRS still wants an annual snapshot: how much came in, how much went out, who's in charge, and whether the org is still doing what it said it would do when it applied for exemption. The IRS states plainly that most organizations exempt from income tax under section 501(a) must file an annual return, and "most small tax-exempt organizations whose annual gross receipts are normally $50,000 or less" satisfy that requirement by filing the e-Postcard, Form 990-N.[1] So "what is the 990" and "what is a 990 tax form" are really the same question with different phrasing: it's the annual disclosure filing that keeps your tax-exempt status active. Skip it and nothing happens the first year. Skip it three years running and your exemption gets pulled automatically, no warning letter, no phone call.[4]
What counts as gross receipts for the $50,000 threshold?
Gross receipts means total revenue before you subtract any expenses. Concession stand sales, raffle ticket sales, membership dues, sponsorship checks, spirit wear sales, all of it counts on the revenue side, and you don't net out your costs first. The IRS defines an organization's gross receipts as "normally $50,000 or less" using a rolling average over three years, not a strict single-year cutoff. Specifically, for organizations in their first three years, it's the average of actual receipts for those years; for organizations that have been around 4-5 years, it's the average of the current year and the two prior years; and for organizations five years or older, it's the average of the current year and the immediately preceding two years.[5] This rolling test matters a lot for booster clubs that have one big fundraiser year (say, a $70,000 gala for a facility upgrade) followed by two quiet years. You might still qualify for 990-N in that big year if the three-year average stays at or under $50,000. Run the actual numbers or confirm with the IRS if you're close to the line; don't eyeball it.
When is Form 990-N due, and what happens if I file late?
Form 990-N is due by the 15th day of the 5th month after your organization's tax year ends. For a calendar-year organization (tax year ending December 31), that's May 15 of the following year.[1] For a fiscal year ending June 30, it's November 15. Here's the part that surprises new treasurers: there's technically no late-filing penalty dollar amount attached to a late 990-N the way there is for the 990 or 990-EZ. But there's a much bigger consequence. The IRS automatically revokes the tax-exempt status of any organization that fails to file its required 990-series return for three consecutive years.[4] The IRS itself describes this as automatic, meaning there's no extra warning notice before revocation kicks in on year three. There's no extension form for 990-N specifically, unlike the full 990 which can get a 6-month extension via Form 8868. If you're late, you just file as soon as you can. One late e-Postcard by itself usually isn't fatal. Three years of silence is.
What happens if my nonprofit's status gets automatically revoked?
Your organization loses federal tax-exempt status, meaning donations made to you are no longer tax-deductible for the donor going forward, and you may owe federal income tax on revenue as if you were a regular taxable entity. The IRS publishes a searchable Tax Exempt Organization Search / Auto-Revocation List so donors and grantmakers can check status before writing a check.[6] The fix is called reinstatement, and the IRS lays out the process in Revenue Procedure 2014-11, which created streamlined retroactive reinstatement options for smaller organizations.[7] If your organization was eligible to file 990-N or 990-EZ for the years it missed, and you apply within specific windows described in that revenue procedure, you can often get reinstated back to the original revocation date, meaning no gap in your tax-exempt status for donor purposes. Reinstatement generally means filing Form 1023 (or 1023-EZ if you qualify) again, along with the past-due 990-series returns for the missed years, plus a user fee. As of the IRS's current fee schedule, Form 1023-EZ costs $275 and the standard Form 1023 costs $600, though you should confirm current fees on the IRS's own Form 1023 instructions page before assuming these numbers, since the IRS updates fee schedules periodically. This is genuinely one of the most common fire drills a new volunteer treasurer walks into: you take over the books, look up your organization on the IRS's exempt org search, and discover the group has been revoked for two years because nobody realized 990-N existed. It's fixable. It's just paperwork and a fee, not a criminal problem.
What is a treasurer, and what does a treasurer do?
A treasurer is the officer responsible for an organization's money: tracking it, reporting on it, and making sure it's spent and recorded the way the bylaws and the law require. In a volunteer group like a booster club, PTO, or youth sports league, the treasurer is usually the only person who touches the bank account regularly and the person who has to answer "where did the money go" at every meeting. So what does a treasurer do, concretely? Day to day: deposits cash and checks, pays bills, reconciles the bank statement monthly, keeps receipts organized, and reports a running balance to the board. Annually: prepares or reviews the budget, files the 990-N (or hands it to whoever does), renews any state charitable registration, and helps prepare for a handoff to the next treasurer. What does a treasurer do in a club specifically, versus a corporate treasurer? The scale is smaller but the responsibility is identical in kind. A club treasurer of a 40-family booster group is doing the same basic job as a Fortune 500 treasurer: safeguard assets, report accurately, follow the rules. The dollar amounts are just three or four fewer zeros. What does a club treasurer do that a general board member doesn't? Signature authority on the bank account, usually. Access to online banking. The job of reconciling every transaction against a receipt or invoice. And, critically for this article's topic, the job of knowing that Form 990-N exists at all, because a lot of outgoing treasurers never mention it during handoff. If you just took over and you're not sure what's already been filed, what's overdue, or where the EIN and prior filings even live, that's normal. Most volunteer treasurer transitions happen with an email and a shoebox, not a briefing document.
Does a booster club or PTO have to file Form 990-N even with almost no money?
Yes, if you're a recognized 501(c)(3) or other tax-exempt organization with an EIN, you generally still file, even in a year with almost no activity. There's no minimum revenue floor below which filing becomes optional; "gross receipts normally $50,000 or less" tells you which form to file (990-N), not whether to file at all. The only real exceptions are organizations specifically excused by the IRS, like churches and certain church-affiliated organizations, and government instrumentalities.[1] A typical booster club, PTO, or youth sports league doesn't fall into those categories. Some small parent groups never formally applied for 501(c)(3) status and don't have their own EIN; they operate loosely under a school's tax ID or as an informal unincorporated association. Those groups don't file their own 990-N because they're not a separate tax-exempt entity in the IRS's eyes. But if your group has its own EIN and received a determination letter at some point, the filing requirement almost certainly applies to you regardless of how little cash moved through the account that year.
How do I know if my organization is even set up to file 990-N, or if it's already been revoked?
Search your organization's name or EIN on the IRS Tax Exempt Organization Search tool. This single search answers three things at once: whether you're currently listed as tax-exempt, whether you're on the auto-revocation list, and what forms you've filed in recent years, since the tool also links to filed 990-series returns where available.[6] If you can't find the organization at all, you may be dealing with a group that never applied for its own exemption, or one that applied under a slightly different legal name than the one everyone uses casually ("Lincoln Middle School Boosters" vs. the actual filed name "Lincoln Middle School Athletic Booster Club Inc"). Pull the EIN letter or a past bank statement to confirm the exact legal name and EIN if the search comes up empty. If you find the org and it says "Revoked," don't panic, but don't ignore it either. Read the reinstatement section above and start gathering the prior years' financial summaries you'll need for the past-due returns.
What records do I need before I sit down to file?
You need less than you'd think for 990-N specifically, since it's genuinely just eight data points, but you need more than that to be confident you're filing the right form and that your numbers are right. Minimum to file 990-N itself: your EIN, legal organization name, any DBA, mailing address, website if you have one, name and address of a principal officer, your tax year, and confirmation of the gross receipts threshold.[1] What you actually need to have done your homework: a full-year income and expense summary (even a simple spreadsheet works) so you can honestly confirm the gross receipts figure, last year's 990-N confirmation email or printout so you know your filing history, and your state's charitable registration renewal date, since that's a separate deadline running on its own clock through your state's charity regulator, not the IRS. This is where a lot of new treasurers realize the prior treasurer left them almost nothing. If that's you, start a simple ledger now, even retroactively for the current year, so next year's filing takes ten minutes instead of a weekend.
Where does the state fit in, and is 990-N enough on its own?
Form 990-N satisfies your federal IRS obligation. It does nothing for any state-level charitable solicitation registration your organization might separately owe. Many states require nonprofits that solicit donations from residents (which includes most booster club and PTO fundraising) to register and renew annually with the state attorney general's office or a dedicated charity regulator, entirely separate from the IRS. These state requirements, fees, and renewal schedules vary a lot and change periodically, so confirm the current rule with your state charity office or attorney general directly rather than assuming last year's requirement still applies. Some states also require a separate registration or bond before you can legally run a raffle, which is a different filing from either the 990-N or general charitable registration. A useful habit: keep a single-page calendar with three dates on it, your federal 990-N due date, your state charitable registration renewal date, and any state raffle license renewal date, so you're not relying on memory across three different agencies with three different clocks.
What should I do at handoff so the next treasurer doesn't inherit this mess?
Write down the EIN, the exact legal name on file with the IRS, the 990-N filing date and confirmation for the last three years, and the state registration renewal date, in one document, physical or digital, that lives with the organization rather than in one person's personal email. This sounds obvious. It almost never happens. Most volunteer treasurer transitions are a folder of receipts and a login password scribbled on a sticky note, and the incoming treasurer spends the first three months just figuring out what's already been filed. That's exactly the gap that leads to accidental three-year revocation streaks; nobody actively decided to skip the filing, it just fell through a leadership change. This is the whole reason a standardized handoff packet is worth building once and reusing every year. BoosterLedger's $99 Treasurer Kit is built around exactly this problem, a one-time, state-personalized packet that documents your EIN, filing history, state registration status, and a repeatable annual checklist so the next volunteer isn't starting from zero. It's not a substitute for actually filing anything, it's the paper trail that makes filing on time possible. For deeper background on the different 990 versions and how the IRS's own e-file system works, 990n and form 990-n cover the mechanics in more detail than fits here.
Frequently asked questions
What is Form 990?
Form 990 is the annual information return most tax-exempt organizations file with the IRS reporting income, expenses, activities, and governance. It's a disclosure document, not usually a tax bill. Which version you file (990-N, 990-EZ, or full 990) depends on your gross receipts and total assets for the year.[2][3]
What is a 990 tax form used for?
It tells the IRS and the public what a tax-exempt organization took in, spent, and did that year, so the government and donors can verify the org still operates within its exempt purpose. Filing it also keeps your tax-exempt status active; skipping it for three straight years triggers automatic revocation.[4]
What is the 990-N e-Postcard?
It's the shortest version of Form 990, an eight-question electronic-only filing for tax-exempt organizations whose gross receipts are normally $50,000 or less. You file it free directly on irs.gov; there's no paper option and no fee.[1]
What does a treasurer do?
A treasurer manages an organization's money: depositing funds, paying bills, reconciling bank statements, reporting balances to the board, preparing budgets, and handling annual filings like Form 990-N and state charitable registration renewals. In a small club, the treasurer is often the only person with regular access to the bank account.
What does a club treasurer do differently from a corporate one?
The core job is the same, safeguard funds and report accurately, just at a smaller scale. A booster club or PTO treasurer typically also files the 990-N personally rather than delegating to accounting staff, and often manages state charitable and raffle registrations without professional help.
How do I file Form 990-N online?
Go to the IRS's e-Postcard filing page on irs.gov, enter your EIN, confirm or update your organization's name and address, add the principal officer's name and address, confirm your tax year and gross receipts are $50,000 or less, and submit. It takes most filers under 15 minutes.[1]
Is there a fee to file Form 990-N?
No. Filing Form 990-N through the IRS's e-Postcard system is free. There's no filing fee, unlike the reinstatement process after revocation, which does involve a Form 1023 or 1023-EZ user fee.[1][8]
What happens if I forget to file 990-N one year?
One missed year alone doesn't trigger automatic revocation, but there's no formal extension for 990-N and no guarantee the IRS won't flag repeated lateness. The real risk is missing three consecutive years, which causes automatic revocation of tax-exempt status with no advance warning notice.[4]
How do I check if my nonprofit's tax-exempt status was revoked?
Use the IRS Tax Exempt Organization Search tool at irs.gov, searching by organization name or EIN. It shows current exempt status, whether you're on the auto-revocation list, and links to recently filed 990-series returns where available.[6]
Can a booster club with $10,000 in revenue skip filing entirely?
No. There's no minimum revenue floor that exempts an organization from filing; even groups with very little activity in a given year generally must file 990-N if they hold a separate EIN and tax-exempt status, unless they fall into a specifically excused category like a church.[1]
What's the difference between 990-N and 990-EZ?
990-N (the e-Postcard) is for organizations with gross receipts normally $50,000 or less; it's eight questions with no financial detail. Form 990-EZ is for organizations with gross receipts under $200,000 and total assets under $500,000, and it requires actual income and expense line items.[3]
Does filing federal Form 990-N cover my state charity registration too?
No. Form 990-N only satisfies the IRS federal filing requirement. Most states with charitable solicitation laws require a separate annual registration or renewal through the state attorney general's office or charity regulator; confirm your state's specific requirement directly with that office.
