Tax form 990-n: the annual e-postcard explained for treasurers

Last updated 2026-07-24

what is a 990 tax form?

The Form 990 series is the annual information return that tax-exempt organizations file with the IRS instead of a corporate income tax return. It's not optional paperwork for big charities only. Nearly every organization recognized as tax-exempt under Section 501(c) has to file some version of it every year, even if the group brought in zero dollars. Think of the 990 series as a sliding scale keyed to money. The bigger your organization's gross receipts and assets, the longer and more detailed the form. A booster club running bake sales and a spaghetti dinner files something very different from a regional hospital system, but both are technically filing "a 990." The IRS explains it plainly: "Tax-exempt organizations, nonexempt charitable trusts, and section 527 political organizations file this form to provide the IRS with the information required by section 6033." ^[1] That's the legal hook. Section 6033 of the Internal Revenue Code is what makes annual reporting mandatory, not a suggestion. For context on the other forms in the family, see the full breakdown of form 990 and how the 990 tax form versions differ.

what is form 990-n (the e-postcard)?

Form 990-N is the smallest version in the 990 family, built for organizations with normally $50,000 or less in gross receipts. The IRS calls it the "e-Postcard" because that's really all it is: eight short questions, filed entirely online, with no financial statements attached. According to the IRS, most small tax-exempt organizations whose gross receipts are normally $50,000 or less "may be required to electronically submit Form 990-N... if they choose not to file Form 990 or Form 990-EZ." ^[2] Note the phrasing: if your receipts are under the threshold, you get to choose the e-Postcard OR file a longer form voluntarily. Nobody chooses the longer form for fun, but it's technically allowed. The eight data points required are basically: your organization's legal name, any other names it uses, mailing address, EIN, tax year, confirmation that gross receipts are $50,000 or less, and a statement that the organization hasn't terminated. That's it. No income statement, no balance sheet, no list of officers' salaries. Compare that to the next size up, Form 990-EZ, which requires a real (if short) income and expense statement. See 990-n and form-990-n for the filing walkthrough itself.

who has to file form 990-n?

You have to file 990-N if your organization is tax-exempt, has gross receipts normally $50,000 or less, and doesn't file the longer 990 or 990-EZ instead. "Normally" is doing some work in that sentence, so it's worth unpacking. The IRS uses a three-year averaging test to figure out if you're "normally" under $50,000. If you're in your first year, you qualify if you expect to receive $75,000 or less. In years two and three, the IRS averages your receipts across the years you've existed. From year four on, it's the average of the current year plus the prior two years. ^[3] A booster club that had one unusually good fundraising year (a big raffle, a large donor gift) doesn't automatically get bumped to the 990-EZ; the averaging smooths that out. A few organizations are excused entirely. Churches, their integrated auxiliaries, and conventions or associations of churches don't have to file any 990 series form at all. ^[3] Most PTOs, boosters, and youth sports leagues don't qualify for that church exception, so this doesn't apply to a typical volunteer treasurer, but it's worth knowing it exists so you don't confuse it with your own group's situation. Organizations included in a group return (some PTAs affiliated with a state or national PTA fall here) may also be covered differently. Confirm with the IRS and, if relevant, your national or state parent organization whether your group is covered by a group filing.

when is the 990-n deadline?

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. ^[2] There's no extension form for 990-N specifically, and there's no late fee assessed the way there is for 990 or 990-EZ. That sounds like good news, and it kind of is, but it hides the real risk: the IRS doesn't track individual late 990-N filings for penalty purposes because the real penalty is structural, not financial. It shows up after three years, not after one late filing. Many volunteer treasurers inherit a group with no clear paper trail on when the fiscal year actually ends. If you're not sure, check the organization's bylaws or its original IRS determination letter, both of which should state the fiscal year. If you genuinely can't find it, confirm with the IRS by calling the Tax Exempt/Government Entities customer account services line.

what happens if you miss the 990-n deadline?

Missing one year's 990-N deadline doesn't trigger a penalty by itself; there's no dollar fine for a late e-Postcard the way there is for the longer forms. The real consequence is cumulative: fail to file for three consecutive years, in any combination of 990, 990-EZ, or 990-N, and the IRS automatically revokes your tax-exempt status. No warning letter is legally required first. The statute behind this is Internal Revenue Code Section 6033(j), added by the Pension Protection Act of 2006. The IRS states it directly: "the law requires automatic revocation of the tax-exempt status of any organization that does not file required Form 990-series returns or notices for three consecutive years." ^[4] The revocation date is retroactive to the filing deadline of the third missed year, not the date the IRS gets around to processing it. Once revoked, your organization has to pay income tax on its revenues (yes, even a booster club's concession stand profits could technically become taxable), loses eligibility for many grants and matching gift programs, and donors lose their charitable deduction for gifts made after the effective revocation date. Reinstatement isn't automatic. It requires filing Form 1023 (or 1023-EZ if eligible) again, along with the delinquent 990-series returns, and, depending on the reinstatement method chosen, possibly a reasonable-cause statement. See irs form 990 for how the reinstatement paperwork stacks with regular annual filing going forward.

how do you file form 990-n?

You file Form 990-N electronically through the IRS website; there is no paper option. As of the current IRS system, filers submit through the IRS's e-Postcard filing portal linked from the Form 990-N landing page on IRS.gov. ^[2] Before you start, gather: your organization's legal name exactly as the IRS has it on file, your EIN, the tax year you're filing for, your mailing address, the name and address of a principal officer, and your organization's website if it has one. You'll also need to confirm the organization's annual gross receipts are $50,000 or less (using the averaging rule above) and that it has not terminated or gone out of business. The process usually takes under 15 minutes once you have the information in hand. There's no fee. You'll get an on-screen confirmation, and the filing typically shows up in the IRS's Tax Exempt Organization Search tool within a few weeks, which is the easiest way to verify a past filing actually went through. If you're taking over as treasurer mid-year and you're not sure whether the prior treasurer filed on time (or at all), search the organization's EIN on the IRS Tax Exempt Organization Search tool before you assume anything. Missing filings hiding in a shoebox of old paperwork is one of the most common surprises a new booster or PTO treasurer finds.

what is form 990 (the longer version)?

Form 990 is the full-length annual information return, required once an organization's gross receipts and assets cross certain thresholds. Generally, you're required to file the full Form 990 (not the EZ or the e-Postcard) if gross receipts are $200,000 or more, or total assets are $500,000 or more. ^[3] The full 990 asks for a real income statement, a balance sheet, compensation for officers and key employees, details on governance policies (conflict of interest policy, whistleblower policy, document retention policy), and a public-facing narrative of your mission and accomplishments. It's a genuinely substantial document; large nonprofits often need a CPA or a dedicated finance staffer to prepare it. Most booster clubs, PTOs, and youth sports leagues never get anywhere near these thresholds. A group running under $50,000 in typical gross receipts stays firmly in 990-N territory unless it has an outlier year that pushes the three-year average up. If you're not sure which bucket your organization falls into this year, the IRS's own "Which Forms Do Exempt Organizations File" page walks through the thresholds in one table. ^[3]

what is form 990-ez and how is it different?

Form 990-EZ sits in the middle: for organizations with gross receipts under $200,000 and total assets under $500,000, but over the $50,000 990-N threshold. It's a four-page form asking for a simplified income statement, balance sheet, and program service descriptions. A lot of mid-sized booster clubs and PTO federations, especially ones with a big annual fundraiser (a gala, a large raffle, a magazine sale drive with real revenue), land here even though they think of themselves as "small." If your organization had a $60,000 year because of one big event, don't assume you're still filing the e-Postcard; check the three-year averaging rule described above. The 990-EZ is genuinely more work than the e-Postcard, but it's still far short of the full 990. Most treasurers can prepare it themselves with a basic spreadsheet of the year's income and expenses, though a lot of groups bring in a bookkeeper or CPA once they cross into this territory just for a second set of eyes.

what does a treasurer do? (the role behind the filing)

A treasurer is the person legally and practically responsible for an organization's money: tracking income and expenses, keeping bank accounts reconciled, and making sure required tax and state filings actually get done on time. In a volunteer group like a booster club, PTO, or youth sports league, the treasurer is usually also the only person who really understands the organization's full financial picture, which is both the point of the role and its biggest risk. Day to day, what does a treasurer do? Concretely: deposits and records income (concession sales, membership dues, sponsorship checks, raffle proceeds), pays approved bills, reconciles the bank statement every month against the books, prepares a financial report for board meetings, and keeps receipts and records organized enough that next year's treasurer (or an auditor) can follow the trail. Annually, the treasurer's job includes making sure the 990-N (or 990-EZ, or full 990, depending on size) gets filed, that any required state charitable solicitation registration is current, and that a raffle license renewal, if the group runs raffles, gets submitted before the event, not after. What does a club treasurer do that's different from a corporate one? Mostly, scale and stakes. A club treasurer of a 40-person youth soccer league is handling the same core responsibilities (deposits, disbursements, reconciliation, filings) as a treasurer of a much bigger organization, just with smaller dollar amounts and, usually, a lot less institutional support. There's rarely a bookkeeper on staff. It's one volunteer with a shoebox or a spreadsheet, which is exactly why missed 990-N filings and lapsed raffle licenses are so common in this world.

what does a treasurer of a club or booster group do, specifically, with the 990-n?

For the specific question of what a club treasurer does with tax filing: the treasurer is usually the person who confirms the organization's EIN, checks the IRS Tax Exempt Organization Search tool to see the filing history, determines which 990 variant applies based on gross receipts, and either files the 990-N directly or hands the numbers to whoever prepares the longer forms. This is one of the areas where a new treasurer taking over mid-year gets burned the most. You inherit the books, you don't know if last year's e-Postcard got filed, and the prior treasurer has moved out of state or stopped answering emails. The fix is boring but effective: pull up the IRS Tax Exempt Organization Search, search your EIN, and look at the filing history before you do anything else. If there's a gap, you want to know now, not after the second missed year. A lot of newer treasurers also don't realize the 990-N filer needs the organization's EIN on file correctly with the IRS; if a prior treasurer used their personal information or an old address, the confirmation and any IRS correspondence might be going to the wrong person entirely. Confirm with the IRS directly if your organization's contact information looks outdated in their system. A $99 one-time State-Personalized Treasurer Kit exists specifically for this handoff moment: it maps your state's specific charity registration and raffle license requirements alongside the federal 990-N rules, so a brand-new volunteer treasurer isn't reconstructing all of this from scratch during their first stressful month on the job.

how does 990-n filing connect to state charity registration and raffle licenses?

Federal 990-N filing and state-level requirements are two separate systems that trip people up because they sound related and often aren't handled by the same office. Filing your 990-N with the IRS does nothing to satisfy a state's charitable solicitation registration requirement, and vice versa. Most states require organizations that solicit donations from the public (which includes most booster clubs selling raffle tickets or soliciting sponsorships) to register with a state charity regulator, usually housed in the Attorney General's office or Secretary of State. Requirements, fees, and exemption thresholds vary significantly by state, so confirm with your state charity office (usually reachable through your state Attorney General's website) whether your organization needs to register and what the renewal cycle looks like. Raffle licensing is its own separate track again, usually administered by a state gaming commission, the Secretary of State, or, in some states, local municipal or county clerks. A lapsed IRS status can sometimes complicate a raffle license application (some states ask for proof of current tax-exempt status), which is one more reason letting the 990-N lapse into automatic revocation causes ripple effects well beyond the IRS relationship itself.

how do you check your organization's 990-n filing history or exempt status?

The fastest way to check is the IRS Tax Exempt Organization Search (TEOS) tool at IRS.gov, which lets you look up an organization by name or EIN and see its determination letter status, its Form 990-series filings, and whether it's listed on the Auto-Revocation List. ^[5] If your organization's name doesn't come up, or comes up with a revocation date, don't panic, but don't ignore it either. Pull the organization's EIN from an old bank statement, a prior tax filing, or the original IRS determination letter, and search directly by EIN rather than name, since name searches can miss variations ("Lincoln High Booster Club" vs. "Lincoln HS Boosters Inc."). If the search shows the organization on the Auto-Revocation List, that's an official confirmation, not a false alarm. The next step is exploring reinstatement options with the IRS. Rev. Proc. 2014-11 lays out the streamlined retroactive reinstatement process for organizations eligible to file Form 990-N or 990-EZ that apply within 15 months of the revocation posting date; other paths exist for organizations that apply later. ^[6] Confirm current requirements and deadlines directly with the IRS since these procedures have been updated over time.

Frequently asked questions

What is a 990 tax form?

Form 990 is the annual information return the IRS requires most tax-exempt organizations to file instead of a corporate income tax return. It comes in several sizes: the full Form 990, the shorter 990-EZ, and the smallest version, Form 990-N (the e-Postcard), based on the organization's gross receipts and assets.

What is the 990-N e-Postcard?

Form 990-N is the shortest IRS annual filing, for tax-exempt organizations with gross receipts normally $50,000 or less. It's free, filed entirely online, and asks eight basic questions like your EIN, legal name, and confirmation the organization hasn't shut down. There's no financial statement attached.

What does a treasurer do?

A treasurer tracks an organization's income and expenses, reconciles bank accounts, pays approved bills, reports financial status to the board, and makes sure required IRS and state filings, like Form 990-N and any state charity registration, get filed on time. In small volunteer groups, the treasurer is often the only person with the full financial picture.

What is a treasurer, exactly, in a booster club or PTO?

In a volunteer organization, the treasurer is the elected or appointed officer legally responsible for the group's money. That includes bookkeeping, bank reconciliation, budget reporting to the board or membership, and making sure annual filings like the 990-N or state raffle license renewals happen on schedule.

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

The core job is the same (track money, reconcile accounts, file required paperwork), but a club treasurer usually works alone, with a much smaller budget, and rarely has a bookkeeper or CPA on staff. That makes small clubs more likely to miss filings like the 990-N simply from lack of institutional memory during officer turnover.

Who is required to file Form 990-N?

Tax-exempt organizations with gross receipts normally $50,000 or less must file some 990-series return, and can choose the 990-N unless they voluntarily file the longer 990 or 990-EZ instead. Churches and certain church-affiliated organizations are generally excused from filing any 990-series return at all.

What happens if you miss the 990-N deadline one year?

Nothing immediate; there's no dollar penalty for one late e-Postcard. The real risk builds over time: three consecutive years of missed 990-series filings triggers automatic revocation of tax-exempt status under IRC Section 6033(j), with no separate warning notice legally required first.

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

Search your organization's EIN or name on the IRS Tax Exempt Organization Search (TEOS) tool at IRS.gov. It shows current exempt status, filing history, and whether the organization appears on the IRS Auto-Revocation List.

What's the difference between Form 990-N, 990-EZ, and the full Form 990?

990-N is for gross receipts normally $50,000 or less (eight questions, no financials). 990-EZ generally applies when receipts are under $200,000 and assets under $500,000 (a simplified income statement and balance sheet). The full Form 990 applies above those thresholds and requires detailed financial and governance disclosures.

Is there a fee to file Form 990-N?

No. Form 990-N is free to file and is submitted directly through the IRS's online e-Postcard system. There is no paper filing option and no processing fee, unlike some paid third-party filing services that charge for help completing it.

Can a small booster club or PTO lose its tax-exempt status?

Yes. Any organization, regardless of size, that fails to file a required Form 990-series return (including the 990-N) for three consecutive years faces automatic revocation under federal law. Small volunteer-run groups are actually at higher risk because of frequent treasurer turnover and thin recordkeeping.

How do you reinstate tax-exempt status after automatic revocation?

Reinstatement generally requires filing Form 1023 or 1023-EZ again with the IRS, along with any delinquent 990-series returns. A streamlined retroactive reinstatement process under Rev. Proc. 2014-11 exists for smaller organizations that apply within 15 months of the revocation posting date; confirm current procedures and deadlines with the IRS directly since rules have changed over time.

Does filing the 990-N satisfy state charity registration or raffle license requirements too?

No. The 990-N is a federal IRS filing only. Most states have a separate charitable solicitation registration, usually through the Attorney General's office, and a separate raffle or gaming license process. Confirm both requirements with your specific state charity office since thresholds and renewal cycles vary widely.
