990-N filing: the e-postcard treasurers actually need

Last updated 2026-07-24

What is Form 990-N?

Form 990-N, officially called the e-Postcard, is the shortest annual information return the IRS offers to tax-exempt organizations. It exists for small nonprofits, booster clubs, PTOs, and youth sports leagues that don't have the income or the staff to file a full Form 990 or the mid-size Form 990-EZ. The IRS created it after Congress passed the Pension Protection Act of 2006, which for the first time required even the smallest tax-exempt groups to file something every year. Before that law, tiny nonprofits under $25,000 in gross receipts didn't have to file anything at all, and a lot of them just fell off the map. The 990-N closed that gap. ^[1] It's not really a tax form in the sense of reporting income and calculating a bill. It just confirms the organization still exists, still qualifies as exempt, and still falls under the small-organization threshold. You answer eight basic questions online. Legal name, EIN, tax year, address, confirmation that gross receipts are $50,000 or less, and a couple of yes/no questions about liquidation or name changes. That's it. ^[2] If you're comparing it to the longer forms, see the overview at form 990 or the plain-English breakdown of the 990 tax form family.

Who has to file the 990-N (the e-Postcard)?

Any organization recognized by the IRS as tax-exempt under section 501(c) whose annual gross receipts are normally $50,000 or less generally must file Form 990-N, unless it chooses to file the longer Form 990 or 990-EZ instead. "Normally" is an IRS term of art, not a casual guess. The IRS defines "normally $50,000 or less" using an averaging test tied to how long the organization has existed:

• In its first tax year, gross receipts of $75,000 or less.
• In its first two years, average annual receipts of $60,000 or less.
• After three years or more, average gross receipts over the most recent three years of $50,000 or less. ^[2] So a booster club that had a huge $70,000 year because it hosted a one-time golf tournament fundraiser isn't automatically bumped out of 990-N eligibility. The IRS looks at the three-year average, not any single year. Most booster clubs, PTOs, and small youth sports organizations fall into this bucket. If your group brings in more than $50,000 on average, you're likely required to file Form 990-EZ or the full Form 990 instead, both of which ask for a lot more financial detail. Check the current thresholds directly, since Congress or the IRS can adjust them; confirm the exact figures with the IRS before you file. Organizations that are NOT eligible to file 990-N include private foundations (they always file Form 990-PF) and section 527 political organizations, which have separate rules. ^[2]

How do you actually file the 990-N online?

You file Form 990-N electronically through the IRS website. There's no paper version and no mail-in option. The IRS retired its old Urban Institute-hosted portal a few years back; filing now happens directly at IRS.gov through the Form 990-N Electronic Filing System (e-Postcard). ^[2] Here's what you need before you start: 1. Your organization's EIN (Employer Identification Number). Not a Social Security number, not a bank account number, the actual nine-digit EIN the IRS assigned when the group first registered. 2. Confirmation of your tax year (calendar year Jan-Dec, or a fiscal year if your bylaws set one). 3. Your legal organization name and mailing address exactly as the IRS has it on file. 4. A statement that gross receipts are normally $50,000 or less. 5. Confirmation the organization has not terminated or gone out of business, plus the name of a principal officer. The whole thing takes most treasurers under 15 minutes once the EIN is in hand. There's no fee. If you're the new treasurer and don't know the EIN offhand, check old bank statements, a prior year's tax filing, or the state charity registration file. Don't apply for a new EIN just because you can't find the old one. That creates a duplicate-entity mess with the IRS that takes far longer to untangle than a phone call to the prior treasurer would have. If your organization has never filed anything with the IRS and you're not sure it even has 501(c)(3) or 501(c)(4) status, start with the broader explainer at irs form 990 before attempting the e-Postcard.

When is the 990-N deadline?

December 31	May 15
June 30	November 15
August 31	January 15
September 30	February 15	Write the deadline on a calendar the day you take over as treasurer. This is the single easiest compliance task in nonprofit finance and also the one most commonly forgotten during a leadership handoff.

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] Unlike income tax filings, there's no extension form for 990-N. You can't file Form 8868 to push the deadline back the way you might for a full Form 990. If you miss May 15, just file late as soon as you catch it. There's no monetary penalty for a late 990-N, but there is a real consequence for missing it repeatedly (see the next section). A quick reference for fiscal-year organizations: | Tax year ends | 990-N due date |

What happens if you miss the 990-N deadline?

Nothing happens after missing it once. The real danger is missing it three years in a row. Under the Pension Protection Act, an organization that fails to file any required 990-series return (including the 990-N) for three consecutive years automatically loses its tax-exempt status, by operation of law, no warning letter required first. ^[1] The IRS states it plainly: "an organization that fails to file required Form 990-series returns for three consecutive years automatically loses its tax-exempt status. The revocation of the organization's tax-exempt status does not take place until the filing due date of the third year." ^[1] This is exactly how so many booster clubs and PTOs end up on the IRS Auto-Revocation List, usually because of leadership turnover. A treasurer graduates their kid out of the program, nobody trains the replacement, three years pass, and suddenly the club that thought it was a registered nonprofit discovers it's actually just an unincorporated group with taxable income and no exempt status. Reinstatement is possible but requires refiling for exemption (often Form 1023 or 1023-EZ again) and sometimes back-filing returns; the IRS has a streamlined retroactive reinstatement process for small organizations that file within 15 months of revocation, but it's not automatic and it's not free. ^[3]

How do you know if your organization is already auto-revoked?

Search the IRS Tax Exempt Organization Search tool directly. It's free, public, and searchable by name or EIN. ^[4] The tool shows current exempt status, the auto-revocation date if applicable, and links to the organization's filed 990-series returns going back several years. If your booster club shows up with a revocation date, don't panic, but don't ignore it either. Any donations made to a revoked organization technically aren't tax-deductible to the donor during the revoked period, which is a real problem if your school district or parents are writing checks assuming a deduction. The fix generally involves filing Form 1023 or 1023-EZ for reinstatement (yes, applying for exemption again, even though you had it before), paying the application fee (currently in the $275 to $600 range depending on form and current IRS fee schedule; confirm the exact current fee on IRS.gov since it has changed over time), and potentially filing the missed 990-N or 990-EZ returns for the lapsed years. ^[3] Groups that catch it within 15 months of the revocation posting date can often use the streamlined retroactive process and keep their original effective date of exemption. Miss that window and reinstatement is usually only effective going forward, which can create a gap year where the organization was, for tax purposes, not exempt at all.

What does a treasurer do (and why does 990-N filing fall on them)?

A treasurer is the volunteer or elected officer responsible for an organization's money: tracking income and expenses, reconciling bank accounts, preparing financial reports for the board or membership, and handling the group's tax and regulatory filings. In a booster club, PTO, or youth sports league, the treasurer is usually the only person who touches the bank account and the only one who knows the EIN exists. What does a club treasurer do day to day? In practice: deposits fundraiser proceeds, pays vendors and reimburses volunteers, keeps receipts organized for an annual review, reports a budget summary at meetings, and files whatever the IRS and state require to keep the group's nonprofit status intact. That last part, the 990-N, is small compared to the rest of the job, but it's the one with the harshest automatic penalty for neglect: three missed years and the exemption is just gone, no hearing, no notice required by statute. ^[1] What does a treasurer do in a club that has no paid staff? Everything a finance department would do in a larger organization, scaled down. Bookkeeping, budgeting, banking, filing, and usually training the next person who takes the job. That handoff step is where 990-N compliance most often breaks down, since the departing treasurer knows the deadline lives in their head and nobody wrote it down anywhere. If you want the fuller job description beyond tax filings (bank reconciliation, dual signers, audit prep), that belongs in a separate discussion of financial controls and handoff procedures, not this filing guide, but it's worth flagging here: the 990-N is one line item on a much longer checklist.

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

Form 990-N (e-Postcard)	Smallest exempt organizations	Normally $50,000 or less
Form 990-EZ	Small to mid-size exempt organizations	Under $200,000, assets under $500,000
Form 990 (full)	Larger exempt organizations	$200,000 or more, or assets $500,000+
Form 990-PF	Private foundations	Any size, mandatory regardless of receipts	A small booster club can generally choose to file the more detailed 990-EZ voluntarily even if it qualifies for the 990-N, sometimes useful if a grant application or bank wants to see actual financial detail. But there's no requirement to do the harder form if you legitimately fall under the $50,000 threshold. For the fuller breakdown of what's on the long forms, see [990](/articles/treasurer-basics/990) and 990n.

Form 990 is the IRS's full annual information return for tax-exempt organizations, the long version with detailed schedules covering revenue, expenses, executive compensation, governance policies, and program accomplishments. It's what larger nonprofits, hospitals, universities, and national charities file. Form 990-EZ is the mid-size version, generally for organizations with gross receipts under $200,000 and total assets under $500,000. Form 990-N (the e-Postcard) is the smallest version, for organizations normally under $50,000 in gross receipts. ^[2] Think of it as three tiers by size: | Form | Who files it | Gross receipts threshold |

What is a 990 tax form used for, exactly?

The 990-series forms exist so the IRS, state charity regulators, and the public can see how a tax-exempt organization raises and spends money, without that organization paying corporate income tax the way a for-profit business would. In exchange for the tax exemption, the organization agrees to public transparency: 990 forms (other than 990-N data, which is minimal) are public record, and sites like the IRS's own database and third-party services publish them for anyone to review. ^[4] For a booster club or PTO, this transparency piece matters more than most volunteers realize. Parents, school administrators, and donors can and sometimes do look up whether the group is actually exempt and whether it's filed on time. A gap in filing history, or a revocation notice, raises real questions at the next parent meeting, especially if someone's trying to decide whether their fundraiser donation is tax-deductible. The 990-N specifically doesn't disclose financial details publicly, since it doesn't ask for any. It's just a status confirmation. If your organization wants or needs to show real financial transparency (say, to a school district that requires proof of good standing to use school facilities), the 990-EZ or full 990 gives more to work with, and some districts specifically ask booster clubs for a copy of the most recent filing before approving fundraising activity on campus.

Common mistakes new treasurers make with 990-N filing

Filing under the wrong EIN. This happens constantly during a treasurer handoff. The prior treasurer used a personal EIN or a school's EIN instead of the club's own, or a new EIN got applied for because the old one was lost, creating two IRS records for what should be one organization. Always confirm the EIN matches IRS records via the Tax Exempt Organization Search before filing. ^[4] Assuming a $0-income year means no filing is needed. It doesn't. Even an organization with zero gross receipts in a given year must still file the 990-N if it wants to preserve its exempt status. "Gross receipts $50,000 or less" includes zero. Forgetting the group even has 501(c) status. Some booster clubs operate for years as an informal group under a school's tax ID or without ever confirming their own exempt status. If you're not sure your organization filed the original exemption application (Form 1023 or 1023-EZ), check the IRS Tax Exempt Organization Search before assuming a 990-N is even the right move. ^[4] Not writing the deadline down anywhere durable. May 15 (for calendar-year filers) needs to live somewhere besides the outgoing treasurer's memory: a shared calendar, a binder, a state filing checklist. Groups on our 990-n hub page and our form 990-n explainer cover the broader filing calendar alongside state-level renewal dates, which often get missed for the same reason. Ignoring the state side entirely. The IRS 990-N only satisfies the federal requirement. Most states with charitable solicitation laws require a separate annual registration or renewal, sometimes with its own financial report, sometimes tied to raffle or gaming licenses. Confirm the state requirement with your state's charity registration office or attorney general's office; this varies enormously by state and changes periodically.

Where does a $99 treasurer kit fit into all this?

None of the 990-N filing steps require paid software or a CPA. It's free, self-service, and designed for exactly the volunteer treasurer situation: no accounting background, limited time, one form. Where a lot of new treasurers actually get stuck isn't the form itself. It's finding the EIN, confirming the tax year, figuring out if the group is already on the auto-revocation list, and knowing what else (state registration, raffle license renewal, bank signer updates) is due around the same time. That's the gap the BoosterLedger State-Personalized Treasurer Kit ($99, one-time, at /treasurer-kit-builder) is built to close: a filing calendar personalized to your state and organization type, a checklist for the EIN and prior-filing lookup, and plain-language explainers for the handoff moment when nobody quite knows what the last treasurer filed. It doesn't file anything for you and it's not a substitute for confirming details directly with the IRS or your state charity office, but it saves the hour of googling that every new treasurer otherwise loses figuring out where to even start.

What should you do right now if you just became treasurer?

First, find the EIN. Check old bank statements, the prior year's 990-N confirmation email, or the state charity registration file. Don't apply for a new one. Second, look the organization up on the IRS Tax Exempt Organization Search to confirm current status and see the filing history. ^[4] This takes two minutes and tells you immediately whether you're dealing with routine annual filing or an auto-revocation recovery project. Third, if status is active and gross receipts are normally under $50,000, file the current year's 990-N through IRS.gov as soon as you have the EIN and tax year confirmed, even if the deadline isn't close yet. There's no reason to wait, and it takes the deadline off your worry list for the year. ^[2] Fourth, check your state's charity registration requirement separately. Federal exemption and state charitable registration are two different systems, and states enforce their own deadlines and forms independently of the IRS calendar. Confirm with your state's charity office or attorney general's office, since requirements and thresholds vary by state and change periodically. Fifth, write down what you found (EIN, tax year, exempt status, filing history, state requirements) somewhere that survives your own departure from the role. The single biggest cause of auto-revocation among small booster clubs isn't confusion about the form. It's institutional memory walking out the door with the last treasurer.

Frequently asked questions

What is Form 990-N?

Form 990-N, called the e-Postcard, is the annual IRS filing for tax-exempt organizations with gross receipts normally $50,000 or less. It's free, filed online at IRS.gov, and asks eight basic questions confirming the organization still exists and still qualifies as a small exempt organization. No financial detail is required.

What is Form 990?

Form 990 is the IRS's full annual information return for tax-exempt organizations, generally required from groups with gross receipts of $200,000 or more or total assets of $500,000 or more. It reports detailed revenue, expenses, and governance information and is publicly available, unlike the minimal data on a 990-N.

What is a 990 tax form used for?

The 990-series forms let the IRS and the public verify that a tax-exempt organization is operating within the rules of its exemption in exchange for not paying corporate income tax. They range from the simple 990-N for small groups up to the detailed full Form 990 for larger nonprofits.

What does a treasurer do?

A treasurer manages an organization's money: tracking deposits and expenses, reconciling bank accounts, reporting finances to the board, and handling required tax and state filings, including Form 990-N for small nonprofits. In a volunteer-run club, the treasurer is usually the only person with full visibility into the finances.

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

A club treasurer, in a booster club, PTO, or youth sports league, typically handles everything alone as a volunteer: banking, budgeting, receipts, and IRS filings like the 990-N, without paid accounting staff. A company treasurer usually has finance department support and different regulatory obligations entirely.

Who needs to file Form 990-N?

Tax-exempt organizations (other than private foundations and section 527 political organizations) with gross receipts normally $50,000 or less must file the 990-N annually unless they choose to file the more detailed Form 990-EZ or full Form 990 instead. "Normally" uses a three-year averaging test set by the IRS.

When is the 990-N due?

The 990-N is due the 15th day of the 5th month after your tax year ends. For calendar-year organizations (year ending December 31), that's May 15. There's no extension form available for 990-N, unlike full Form 990 filings.

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

One missed year has no direct penalty. But missing required 990-series filings for three consecutive years triggers automatic revocation of tax-exempt status under the Pension Protection Act, with no advance warning required by law. Reinstatement then requires reapplying for exemption and possibly back-filing returns.

How do I check if my nonprofit already lost its tax-exempt status?

Search your organization's name or EIN in the IRS Tax Exempt Organization Search tool at IRS.gov. It shows current exempt status, any auto-revocation date, and a history of filed 990-series returns, all free and public.

Does filing the 990-N cost anything?

No. Filing Form 990-N is free through the IRS website. If your organization has been auto-revoked and needs to reapply for exemption, that reinstatement application (Form 1023 or 1023-EZ) does carry an IRS user fee, currently in the low hundreds of dollars; confirm the exact current amount on IRS.gov.

Can a booster club or PTO file the 990-N instead of a full 990?

Yes, as long as gross receipts are normally $50,000 or less using the IRS's averaging test. Most booster clubs and PTOs qualify. If average receipts exceed that threshold, the organization must file Form 990-EZ or the full Form 990 instead.

Is Form 990-N the same as a tax return?

Not in the traditional sense. It doesn't report income for tax calculation purposes since the organization is tax-exempt. It's a status confirmation filing: name, EIN, tax year, address, and confirmation that receipts stay under the small-organization threshold.

Do I still need to file 990-N if my organization had zero income this year?

Yes. Zero gross receipts still counts as "normally $50,000 or less," and the filing requirement doesn't disappear in a slow or inactive year. Skipping it in a low-income year still counts toward the three-year auto-revocation clock.

Does 990-N filing replace state charity registration requirements?

No. The 990-N only satisfies the federal IRS requirement. Most states with charitable solicitation laws require separate annual registration or renewal, often with its own deadline and sometimes tied to raffle or gaming licenses. Confirm requirements directly with your state's charity registration office or attorney general.
