How to file form 990-n (e-postcard): the treasurer's guide

Last updated 2026-07-24

what is form 990-n, and who has to file it

Form 990-N, nicknamed the e-postcard, is the shortest annual report the IRS accepts from tax-exempt organizations. It exists for one reason: small nonprofits, the kind run by volunteers with a shoebox of receipts, still owe the IRS something every year, but a full financial statement would be overkill. You qualify to file the 990-N instead of a longer 990 or 990-EZ if your organization's gross receipts are normally $50,000 or less. The IRS defines "normally" using a rolling average over your most recent three tax years, more than the current one, so a single big fundraiser year doesn't automatically bump you up ^[1]. Most booster clubs, small PTOs, youth sports leagues, and similar all-volunteer groups fall into this bucket. If your group brings in more, you'll file Form 990-EZ or the full Form 990 instead, both of which ask for a lot more detail. One thing that trips people up: churches and certain church-affiliated organizations are not required to file annual returns at all, 990-N included ^[2]. If that's not you, and you're a 501(c)(3) or other tax-exempt group under the gross receipts threshold, the e-postcard is almost certainly your filing.

what does a treasurer do (and why does 990-n land on their desk)

A treasurer keeps the organization's money honest and its paperwork current. That's the one-sentence version. In practice, what a treasurer does includes tracking every dollar in and out, reconciling the bank account, preparing budget updates for the board, and making sure state and federal filings happen on time, 990-N being one of the smallest but most consequence-heavy of those. What does a treasurer do in a club, specifically? Usually: collect dues and fundraiser proceeds, pay vendors and refs and venue fees, keep receipts organized enough that someone else could audit them, and report finances at meetings. A club treasurer also tends to be the person who knows the EIN off the top of their head, because they're the one typing it into the IRS e-postcard system every year. What does a treasurer of a club do that a regular board member doesn't? Signature authority on the bank account, usually. Access to the accounting software or ledger. And often, sole responsibility for tax filings, which is exactly the kind of single-point-of-failure setup that gets small nonprofits auto-revoked. If the treasurer changes jobs, gets busy, or just forgets, and nobody else has visibility into the org's IRS filing status, three years can slip by fast. This is the actual reason 990-N matters more than its 10-minute filing time suggests: it's usually one person's job, and that person is a volunteer with a life outside the booster club.

what information do you need before you file

Gather these before you sit down at the computer, because the e-postcard portal times out and re-starting because you had to go dig up your EIN is annoying. You'll need: your organization's legal name and any "doing business as" name, your mailing address, your Employer Identification Number (EIN), the name and address of a principal officer, your tax year (calendar or fiscal), and a written statement confirming gross receipts are still $50,000 or less ^[1]. You'll also confirm whether the organization has terminated or gone out of business. That's it. Eight data points, no financial statements, no attachments. If you don't know your EIN, don't apply for a new one. Check old bank statements, prior tax filings, or call the IRS Business and Specialty Tax Line. A duplicate EIN creates a mess that outlasts any convenience of skipping a phone call.

how do you actually file the 990-n e-postcard

File Form 990-N through the IRS's own online system. As of the 2021 filing changes, the IRS moved e-postcard filing from the old Urban Institute-hosted site to IRS.gov directly, so make sure you're on an actual irs.gov page, not a third-party site charging a "processing fee" for something that's free ^[1]. The steps: go to the IRS Form 990-N landing page, register or log in with an IRS username (via Login.gov or ID.me credentials), enter your EIN, verify your organization is in the system, fill in the eight data points above, and submit. The IRS states most filers can complete it "in a matter of minutes" ^[1]. You'll get an on-screen confirmation, and the filing status shows up (with some lag) in the IRS's Tax Exempt Organization Search tool. Print or screenshot that confirmation. It's the only proof you filed, and "the website said I did it" isn't going to help you three years later if there's a dispute.

when is form 990-n due

Form 990-N is due by the 15th day of the 5th month after your organization's tax year ends ^[3]. For a calendar-year organization (tax year ending December 31), that's May 15 of the following year. If your fiscal year ends June 30, your 990-N is due November 15. There's no extension form for the 990-N itself the way there is for the longer 990 forms; if you file late, there's technically no monetary penalty for a late e-postcard, but repeated non-filing is what triggers automatic revocation, which is a much bigger problem than a late fee ^[4]. Mark the due date on a real calendar, more than in your head. Better yet, put it on the organization's shared calendar, more than the treasurer's personal one, so the filing doesn't disappear when the treasurer role changes hands.

what happens if you miss the deadline, or miss it three years running

Missing one year isn't a crisis by itself. There's no late fee attached to a missed 990-N the way there is for the longer forms ^[4]. But the IRS tracks filings by year, and federal law is specific about what happens next: "failure to file required Form 990 series returns or notices for three consecutive years will result in automatic revocation of tax-exempt status" . That's the sentence every treasurer should tattoo somewhere visible. Three consecutive years, automatic, no warning letter, no phone call. The revocation takes effect on the filing due date of the third missed year, and the IRS then publishes the organization's name on its Auto-Revocation List . Donors checking IRS Form 990 status or doing due diligence before a grant will find it there. Once revoked, your organization owes federal income tax on its revenue going forward until reinstated, loses eligibility for tax-deductible donations, and often loses state-level tax exemptions and grant eligibility that were tied to federal status. Getting reinstated means filing Form 1023 or 1023-EZ again (yes, the original exemption application) plus a reasonable cause statement, and paying the applicable user fee . It's not impossible, but it's hours of work and real cost for something that would have taken 10 minutes a year to avoid.

how do you check if your organization already lost its status

Search your organization's name or EIN in the IRS Tax Exempt Organization Search (TEOS) tool. It shows current exempt status, whether the organization is on the Auto-Revocation List, and (going back a few years) which forms were filed and when . Do this the day you take over as treasurer, before you do anything else. It's the single fastest way to find out if you've inherited a clean filing history or a three-year gap that's about to blow up. If your organization shows up on the Auto-Revocation List, don't panic, but don't wait either; the reinstatement process has its own deadlines and options depending on how long it's been revoked, and those details are genuinely worth confirming with the IRS directly, since procedures shift and this isn't the place for guesswork.

990-n vs 990-ez vs full 990: which one is yours

Form	Gross receipts threshold	What it asks for	Typical time to prepare
990-N (e-postcard)	$50,000 or less (normally, 3-year average)	8 basic data points	About 10 minutes
990-EZ	Less than $200,000 gross receipts AND less than $500,000 total assets	Summary financial statement, program service info	Several hours to a day
990 (full)	$200,000+ gross receipts OR $500,000+ total assets	Full financial statements, governance, compensation	Days, often needs a preparer	These thresholds come directly from the IRS's own instructions for which return to file . If you're not sure which bucket you're in because your fundraiser income swings year to year, use the three-year average of gross receipts, more than this year's number; that's the actual test the IRS applies [1]. A lot of booster clubs assume they're automatically 990-N eligible because they're small and volunteer-run. Check the math. A single unusually good fundraising year, or one year with a big raffle payout counted as gross receipts, can push the three-year average over $50,000 and require an 990-EZ instead. Compare 990-N to 990-EZ more closely if your numbers are anywhere near that line.

what if your gross receipts go over $50,000 mid-year

You don't switch forms mid-year. You file based on your organization's gross receipts for the tax year that just ended, averaged with the two years before it. If this year pushed you over, but the three-year average is still at or under $50,000, you can likely still file the 990-N for this year and reassess next year ^[1]. If the three-year average is now over $50,000, you'll need to step up to Form 990-EZ (or the full 990, depending on assets) for that tax year. That means gathering actual financial statements, program expense breakdowns, and possibly getting help from someone with nonprofit accounting experience, since the EZ and full 990 ask questions a shoebox ledger won't answer cleanly. This is a good moment to build a real bookkeeping system if you haven't already, because "we grew out of the e-postcard" is a good problem, but only if your records grew with it.

does form 990-n replace state filings too

No. Form 990-N is a federal filing only, submitted to the IRS. Most states have their own separate charity registration and annual reporting requirements, often through the Attorney General's office or a Secretary of State charities division, and those are entirely separate paperwork with their own deadlines and fees. Don't assume filing the e-postcard checks every box. Confirm with your state charity office (search "[your state] charitable organization registration" or check your Attorney General's website) what annual filing, if any, your booster club or PTO owes at the state level. Some states exempt small all-volunteer organizations from registration; others don't. This varies enough by state that guessing wrong is common, and it's worth a five-minute phone call to your state office rather than assuming.

a quick word on why this matters more than it looks like it should

Ten minutes a year, free, eight questions. It's easy to see why treasurers let 990-N slip when there's a bake sale to run and uniforms to order. But the automatic revocation rule doesn't care how busy your season was. It's mechanical: three years, gone, published publicly . We built the State-Personalized Treasurer Kit partly because of this exact failure mode: a treasurer hands off the books, the new person doesn't know the EIN exists, and two filing years pass before anyone checks. It's a one-time $99 kit with your state's specific forms, deadlines, and a filing calendar built in, so the 990-N due date isn't just floating in one volunteer's memory. It's not legal or tax advice, and it doesn't file anything for you or guarantee any outcome; it's a reference built so the next treasurer isn't starting from zero. Whatever system you use, the fix is the same: write the due date somewhere that survives a change in treasurer, and check TEOS once a year to confirm the filing actually went through.

Frequently asked questions

what does a treasurer do?

A treasurer tracks all money in and out for an organization: dues, fundraiser proceeds, vendor payments, and bank reconciliations. They report finances to the board, keep receipts organized, and handle required filings like Form 990-N. In a small nonprofit, the treasurer is often the only person who knows the EIN and login credentials for IRS filings.

what is a treasurer?

A treasurer is the officer responsible for an organization's money: collecting it, paying it out, recording it, and reporting on it. In booster clubs and PTOs, it's usually an elected or appointed volunteer role with bank signature authority and responsibility for annual IRS and state filings.

what do treasurers do day to day?

Day to day, a treasurer deposits checks, pays invoices, tracks fundraiser income and expenses, reconciles the bank statement monthly, and keeps a simple ledger or spreadsheet current. Around tax season, they also handle the 990-N or 990-EZ filing and any state charity report that's due.

what is form 990?

Form 990 is the IRS's annual information return for tax-exempt organizations. It has three versions based on size: the full Form 990 for larger organizations, Form 990-EZ for mid-size ones, and Form 990-N (the e-postcard) for organizations with $50,000 or less in gross receipts.

what does a treasurer do in a club?

In a club setting, the treasurer manages dues collection, event fundraising proceeds, vendor and facility payments, and the club's bank account. They also typically own the club's tax-exempt paperwork, including filing Form 990-N each year and keeping records ready in case a board member or auditor asks to see them.

what does a club treasurer do that other officers don't?

Unlike other officers, the treasurer usually has sole or shared signature authority on the bank account and is the point person for financial and tax filings. They're the one who can answer, at any given moment, how much money the club has and where it went, and they're accountable for the IRS 990-N deadline.

what is a 990 tax form?

A 990 tax form is the informational return tax-exempt organizations file annually with the IRS instead of a traditional income tax return, since they generally don't owe income tax. It reports gross receipts, activities, and (for larger orgs) governance and compensation details, so the IRS and public can see how the organization operates.

what is the 990?

"The 990" usually refers to the IRS's annual return for tax-exempt organizations, filed in one of three versions (990, 990-EZ, or 990-N) depending on gross receipts and total assets. It's how nonprofits maintain their tax-exempt status and stay off the IRS's automatic revocation list.

what does a treasurer of a club do if the club has no paid staff?

If there's no paid staff, the treasurer often does everything financial themselves: bookkeeping, deposits, bill pay, budget reports, and the annual 990-N filing. This concentration of duties is exactly why many small clubs build in a second signer on the bank account and a backup person who knows the EIN and filing login.

how much does it cost to file form 990-n?

Filing Form 990-N costs nothing. It's a free filing directly through the IRS website. Be wary of any third-party site charging a fee to "process" your e-postcard filing; the IRS system itself has no charge for eligible organizations.

how long does it take to file the 990-n e-postcard?

The IRS describes the 990-N as something "most filers can complete in a matter of minutes," since it only asks for eight basic pieces of information: legal name, EIN, tax year, address, principal officer, and a gross receipts confirmation. Having your EIN and prior filing info ready in advance speeds it up further.

what happens if a nonprofit doesn't file form 990 for three years?

Federal law automatically revokes tax-exempt status if an organization fails to file any required 990-series form (including the 990-N) for three consecutive years, with no warning letter required. The organization then owes income tax going forward and appears on the IRS's public Auto-Revocation List until reinstated.

can you file form 990-n late?

Yes, there's no monetary penalty attached to filing a single 990-N late, and the IRS allows filing for a prior missed year through the same online system. The real risk isn't lateness itself, it's letting three consecutive years lapse without filing, which triggers automatic revocation regardless of intent.

how do you know if your organization qualifies for the 990-n instead of 990-ez?

Check your gross receipts averaged over the most recent three tax years. If that average is $50,000 or less, you qualify for the 990-N. If it's higher but under $200,000 (with total assets under $500,000), you'll need the 990-EZ instead.
