990-N tax filing: who must file and how it works

Last updated 2026-07-25

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

Form 990-N, nicknamed the e-Postcard, is the shortest annual information return the IRS offers to tax-exempt organizations. It exists for one reason: small nonprofits still have to report to the IRS every year, but Congress didn't want to bury a $12,000-a-year youth soccer league in paperwork built for hospitals and universities. The IRS describes it plainly: "Most small tax-exempt organizations whose annual gross receipts are normally $50,000 or less are required to electronically submit Form 990-N... unless they choose to file a complete Form 990 or Form 990-EZ instead" ^[1]. That's the whole eligibility test in one sentence. If your booster club, PTO, or youth sports league brings in $50,000 or less on average, this is almost certainly your form. It is filed entirely online, it's free, and it asks eight questions. No balance sheet, no schedules, no signatures on paper. You'll want to read our overview of Form 990 if you're not sure which version of the 990 family applies to your group, since the $50,000 line is what separates 990-N filers from everyone else.

Who has to file Form 990-N?

Any organization recognized as tax-exempt under section 501(c) that normally has $50,000 or less in annual gross receipts must file the 990-N, unless it chooses to file the longer 990-EZ or full 990 instead ^[1]. "Normally" matters here: the IRS uses an averaging test over three years, not a single bad (or great) year, to decide if you qualify. The IRS's own gross receipts test for 990-N eligibility works like this: an organization is treated as having gross receipts of $50,000 or less if (1) it's been in existence one year or less and received $75,000 or less during its first tax year, (2) it's been in existence between one and three years and averaged $60,000 or less in its first two years, or (3) it's been around three years or more and averaged $50,000 or less over the immediately preceding three tax years ^[1]. A few groups are carved out entirely. Private foundations always file Form 990-PF regardless of size, and section 527 political organizations have their own rules ^[1]. Churches and certain church-affiliated organizations are generally exempt from filing any 990 at all. Everyone else in the small-nonprofit lane, PTOs, booster clubs, rec leagues, alumni groups, tends to land in 990-N territory unless a big fundraiser or grant year pushes them over.

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

You file at IRS.gov, not through mail and not through a third-party accountant unless you want to pay one. The IRS runs the e-Postcard through its own portal, and as of the 2023 filing season, filers use an IRS.gov account (the same login system used for other IRS online services) rather than the older third-party Urban Institute site ^[2]. You'll need: your EIN, your legal name and any "doing business as" name, your mailing address, your tax year, confirmation that gross receipts are $50,000 or less, and a yes/no answer on whether the organization is going out of business ^[2]. That's it. Most treasurers finish in under 15 minutes once they have the EIN and address in front of them. There's no login fee and no filing fee. If you've inherited a shoebox of paperwork and don't know your organization's EIN or its 990-N filing history, the IRS Tax Exempt Organization Search tool lets you look up past e-Postcard submissions and current exempt status by name or EIN ^[3]. That search is often the fastest way for a new treasurer to figure out whether the last person actually filed anything.

When is the 990-N due?

The 990-N is due on the 15th day of the 5th month after your organization's accounting period ends ^[1]. For a calendar-year organization (tax year ending December 31), that means the filing is due May 15 of the following year. There's no extension available for Form 990-N. The IRS states directly: "There is no penalty assessment for a late-filed Form 990-N. However, an organization that fails to file required Form 990s (either Form 990, 990-EZ or 990-N) for three consecutive years will lose its tax-exempt status" ^[1]. So skipping one year quietly costs nothing in dollars, but it starts a clock. If your fiscal year runs July 1 to June 30, like many school-affiliated booster clubs, your 990-N deadline is November 15. Get your fiscal year end wrong and you'll file late without realizing it, so check the date on your original IRS determination letter or your EIN confirmation notice (Form CP 575) before assuming a May 15 deadline applies.

What happens if you don't file the 990-N?

Nothing happens after one missed year. Nothing happens after two. The trouble starts on year three: miss three consecutive annual filings (990, 990-EZ, or 990-N in any combination) and the IRS automatically revokes your tax-exempt status by operation of law under Internal Revenue Code section 6033(j) ^[4]. This catches a lot of volunteer-run groups off guard specifically because there's no late fee or warning letter along the way for 990-N filers. A booster club can go three treasurer handoffs in a row, each one assuming the prior person filed, and wake up to discover the IRS revoked their exemption two years ago without anyone getting a notice that felt urgent. Once revoked, the organization's name shows up on the IRS Auto-Revocation List, donations are no longer tax-deductible to donors, and (depending on your state) you may lose state sales tax exemption or charitable registration standing too. Reinstatement isn't automatic; you generally have to reapply for exempt status using Form 1023 or 1023-EZ and, in many cases, pay the filing fee again. The IRS does offer streamlined retroactive reinstatement for organizations that missed the deadline and qualify for 990-N or 990-EZ, if you apply within 15 months of the revocation date or the date on the revocation letter ^[5]. Miss that window and reinstatement gets more expensive and more paperwork-heavy. If you're staring at a revocation notice right now, our guide to Form 990 walks through what full reinstatement involves versus streamlined.

What is Form 990, and how is it different from the 990-N?

990-N	Booster clubs, PTOs, small leagues	Normally ≤ $50,000 [1]	Online only, IRS.gov	Free
990-EZ	Mid-size nonprofits	< $200,000 and assets < $500,000	Paper or e-file	Free to file; may need paid prep
Form 990	Larger nonprofits	$200,000+ or assets $500,000+	E-file required for most	Free to file; often needs a preparer
990-PF	Private foundations	Any size	E-file required	Free to file; typically needs a preparer	See our full breakdown at 990 tax form if you're trying to figure out which of the four your group actually needs this year, especially if a single big fundraiser pushed you over $50,000.

Form 990 is the IRS's annual information return for tax-exempt organizations, the umbrella term that covers four versions scaled to size: the full Form 990, the mid-size Form 990-EZ, the small-org Form 990-N, and the private foundation Form 990-PF ^[1]. The difference between them is almost entirely about gross receipts and total assets. Organizations with gross receipts under $200,000 and total assets under $500,000 generally qualify for Form 990-EZ instead of the full Form 990 . Anything above that, or organizations that simply choose to file more detail, file the full Form 990, which includes financial statements, compensation disclosures, and multiple schedules. | Form | Typical filer | Gross receipts | Filing method | Cost |

What does a treasurer do?

A treasurer is the person in a club, booster organization, or PTO responsible for tracking money in, money out, and making sure the organization's financial obligations, including tax filings, actually get done on time. It's a volunteer role in most youth-sports and school-affiliated groups, but the responsibilities are the same ones a paid bookkeeper would carry in a small business. Day to day, what a treasurer does usually breaks into four buckets: recordkeeping (deposits, receipts, a running ledger), reporting (monthly updates to the board, an annual budget summary), compliance (filing the 990-N or 990-EZ, renewing any state charitable registration, tracking sales tax exemption paperwork), and controls (making sure no single person handles cash alone, reconciling the bank statement against the books every month). What does a treasurer do in a club specifically, versus a company? Mostly the same core job, scaled down. A club treasurer signs checks or approves electronic payments, keeps the checkbook or accounting software current, prepares a year-end financial summary for members, and is usually the one who has to explain to the board why the IRS sent a letter. The stakes are lower in dollar terms but the exposure is personal: a treasurer who misses three years of 990-N filings is the one fielding calls from confused board members when the exemption disappears.

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

What does a treasurer of a club do that a corporate treasurer doesn't? Mostly, a club treasurer works with far less infrastructure. There's usually no accounting department, no CFO to check the numbers, and no dedicated compliance staff. One volunteer often does the bookkeeping, the filing, the bank reconciliation, and the budget presentation, sometimes all in a single evening before a board meeting. That concentration of duties is exactly why cash handling controls matter more, not less, in a small club. A single person controlling deposits, disbursements, and the books with no second set of eyes is a textbook setup for both honest mistakes and, occasionally, theft that goes undetected for years. Groups that split duties, one person collects and deposits, another reconciles and reports, catch errors faster and protect the volunteer treasurer from unfounded suspicion later. A club treasurer also tends to inherit history nobody documented. Bank logins nobody wrote down. A 990-N filing streak nobody tracked. An EIN nobody can find. Part of the job, especially in year one, is just reconstructing what already happened before you can plan what happens next.

What is a 990 tax form, in plain terms?

A 990 tax form is the IRS's way of making tax-exempt organizations show their work publicly. Because these organizations don't pay income tax, the IRS (and the public) rely on the 990 series to see where the money came from and where it went, instead of relying on a corporate income tax return. Unlike most tax filings, 990s are public documents. Anyone can look up a nonprofit's Form 990 or 990-EZ through the IRS Tax Exempt Organization Search or through nonprofit databases that republish them ^[3]. Donors, grantmakers, and journalists use this routinely to check how a nonprofit spends money before writing a check or a story. The 990-N is the exception to the transparency-through-detail idea: because it's just eight data points, there's very little financial detail to see. That's the tradeoff for small orgs. You get a free 10-minute filing, but you also don't get to show donors the fuller financial picture a 990-EZ or full 990 would provide. Some small nonprofits choose to file the 990-EZ voluntarily, even though they qualify for the N, specifically because grant applications and some state charity regulators want to see more than an e-Postcard on file. For a side-by-side on what the full form asks for, see IRS Form 990.

What if your gross receipts go over $50,000 partway through the year?

You file the 990-EZ or full Form 990 for that year instead of the 990-N, based on the three-year averaging test described above, not a strict single-year cutoff ^[1]. A single unusually good fundraising year, a big raffle, a capital campaign for new uniforms, doesn't automatically bump you out of 990-N eligibility if your trailing three-year average still lands at $50,000 or less. In practice, this trips up booster clubs after a banner year: a car wash and concessions program that normally nets $30,000 suddenly clears $70,000 because of a one-time equipment fundraiser. Run the three-year average before assuming you need the bigger form. If the average is still under $50,000, the 990-N remains correct. If you're consistently running above $50,000, plan on filing the 990-EZ going forward and budget time (or a modest fee for a preparer) accordingly. The 990-EZ isn't free in the time-cost sense the 990-N is; it requires an actual balance sheet and revenue statement, which means your bookkeeping needs to be clean enough to produce one.

How do you catch up if you missed a 990-N filing?

First, check your actual status before assuming the worst. Use the IRS Tax Exempt Organization Search to see whether your organization appears on the Auto-Revocation List and to check your last filed 990-N ^[3]. A missed year doesn't mean revocation; it takes three consecutive misses. If you're not revoked, just late, file the current year's 990-N as soon as you can. There's no late penalty specifically for the e-Postcard ^[1], so there's no financial reason to delay once you realize you're behind, only reputational and compliance risk if it slides another year. If you are on the Auto-Revocation List, check whether you qualify for streamlined retroactive reinstatement, generally available to organizations eligible to file 990-N or 990-EZ that apply within 15 months of the revocation date, using Form 1023 or 1023-EZ with the appropriate IRS notation ^[5]. Past the 15-month window, reinstatement typically requires a full Form 1023 application and, often, an explanation of reasonable cause for the delinquency, which is a heavier lift. Confirm your state's rules too. State charity registration offices and attorneys general track exempt status independently, and a federal revocation can trigger state-level compliance letters even after you fix the IRS side. This is exactly the kind of multi-agency mess a 990-N filing habit, done every single year on a calendar reminder, prevents in the first place.

Practical checklist for a new treasurer handling the 990-N

If you just took over the books and don't know where things stand, here's the order that actually works. Start with identity: find the EIN (check old bank statements, the original IRS determination letter, or Form CP 575). Then check status: run the EIN through the IRS Tax Exempt Organization Search to see current exempt status and 990-N filing history ^[3]. Next, confirm the fiscal year end, since that sets your actual due date (15th day of the 5th month after year-end, not automatically May 15) ^[1]. Then gather the eight data points the 990-N asks for: legal name, any DBA, mailing address, website (if any), confirmation of gross receipts at or under the threshold, and the going-concern question. Finally, file it, screenshot the confirmation, and put next year's date on a calendar with a 60-day-early reminder, not a due-date reminder. A booster club that builds this into a fixed annual habit, rather than a scramble each spring, essentially eliminates its own auto-revocation risk. Our $99 State-Personalized Treasurer Kit builds this exact filing calendar and document checklist around your specific state and fiscal year, which is genuinely the fastest way to stop guessing whether last year's filing actually happened.

Frequently asked questions

What does a treasurer do?

A treasurer tracks all money moving through an organization, deposits, expenses, reimbursements, and makes sure required filings like the 990-N happen on time. In a booster club or PTO, this usually means keeping the checkbook current, reconciling bank statements monthly, reporting to the board, and handling IRS and state compliance paperwork.

What is a treasurer?

A treasurer is the officer responsible for an organization's finances: recordkeeping, reporting, and compliance. In volunteer groups like booster clubs, PTOs, and youth sports leagues, it's typically an elected or appointed unpaid position, but the legal and financial responsibilities mirror what a paid bookkeeper does for a business.

What is Form 990?

Form 990 is the IRS's annual information return for tax-exempt organizations, covering the full Form 990, the mid-size 990-EZ, the small-org 990-N (e-Postcard), and the private foundation 990-PF. Which version you file depends mainly on gross receipts and total assets, with $50,000 in gross receipts being the key line for 990-N eligibility ^[1].

What is a 990-N and who needs to file it?

Form 990-N (the e-Postcard) is a free, eight-question online filing for tax-exempt organizations with gross receipts normally $50,000 or less over a trailing three-year average ^[1][2]. Most booster clubs, PTOs, and small youth sports leagues fall into this category. It's due the 15th day of the 5th month after your fiscal year ends.

What is the 990 tax form used for?

The 990 series lets the IRS and the public see how tax-exempt organizations raise and spend money, since these organizations don't file income tax returns. Nonprofits report revenue, expenses, and (for the larger forms) compensation and program details. The 990-N version reports almost none of that detail, just identity and a receipts confirmation.

What happens if a nonprofit doesn't file its 990 for three years?

The IRS automatically revokes tax-exempt status after three consecutive years of missed 990, 990-EZ, or 990-N filings, under Internal Revenue Code section 6033(j) ^[5]. There's no warning letter specific to this trigger for 990-N filers, so many small organizations don't realize they're revoked until a donor or bank asks about exempt status.

Is there a penalty for filing the 990-N late?

No. The IRS states there is no penalty assessment for a late-filed Form 990-N ^[1]. The real risk isn't a fee, it's the three-consecutive-year rule: miss three years running and your tax-exempt status is automatically revoked, which is far more costly to fix than any late fee would have been.

How do you know if your organization qualifies for the 990-N instead of the 990-EZ?

You generally qualify for 990-N if gross receipts are normally $50,000 or less, using the IRS's three-year averaging test for established organizations (or modified tests for organizations less than three years old) ^[2]. If your trailing average is over $50,000, you likely need the 990-EZ or full Form 990 instead.

Can you file Form 990-N by mail?

No. Form 990-N must be filed electronically through the IRS's online system; there's no paper version ^[1][3]. Filers now use an IRS.gov account to submit it, following a 2023 change away from the older third-party filing portal.

How do you check if your nonprofit is on the IRS Auto-Revocation List?

Use the IRS Tax Exempt Organization Search tool at irs.gov, searching by organization name or EIN, which shows current exempt status, revocation history, and past 990-N filings ^[4]. This is the fastest way for a new treasurer to confirm whether prior filings actually happened.

How does an organization get reinstated after IRS auto-revocation?

Most small organizations apply for streamlined retroactive reinstatement using Form 1023 or 1023-EZ, available to groups eligible to file 990-N or 990-EZ that apply within 15 months of the revocation date ^[6]. Past that window, reinstatement generally requires a full application and an explanation of reasonable cause, which takes longer and often costs more.

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

A club treasurer usually handles every financial task alone, bookkeeping, deposits, filings, and board reporting, without the accounting staff or internal controls a company would have. That concentration makes clear cash-handling controls and duty separation more important, not less, since one volunteer often has unchecked access to the books.

Do booster clubs and PTOs actually have to file anything with the IRS every year?

Yes, if they hold 501(c) tax-exempt status. Nearly all exempt organizations must file some version of the 990 annually, and most small booster clubs and PTOs qualify for the free, eight-question 990-N ^[1]. Skipping this for three straight years triggers automatic revocation of exempt status under IRC 6033(j) ^[5].
