990-N filing requirements: who must file and how

Last updated 2026-07-25

What is Form 990-N?

Form 990-N, also called the e-Postcard, is the shortest annual report the IRS requires from small tax-exempt organizations. It is not a paper form. You file it online through the IRS website, and it takes maybe ten minutes if you have your information ready ^[1]. The form asks for eight things: your organization's legal name and any doing-business-as names, your Employer Identification Number (EIN), your mailing address, your website if you have one, the name and address of a principal officer, your tax year, confirmation that your annual gross receipts are normally $50,000 or less, and a statement if you've gone out of business ^[1]. That's it. No revenue detail, no expense breakdown, no program description. Compare that to the full Form 990 or the mid-size 990-EZ, which ask for financial statements, board lists, and program service accomplishments. The e-Postcard exists specifically so tiny nonprofits, the kind run by volunteer treasurers with a shoebox of receipts, don't need an accountant just to stay compliant. One quick vocabulary note: people sometimes call this "the 990 tax form," but Form 990-N isn't really a tax form in the sense of calculating tax owed. Exempt organizations generally don't owe income tax on program-related revenue. The ^[990](/articles/treasurer-basics/990) family of forms, including the 990-N, is an information return. It tells the IRS you still exist and roughly what size you are.

Who has to file 990-N?

Most tax-exempt organizations recognized under Internal Revenue Code Section 501(c) must file an annual return with the IRS, and which version depends on gross receipts and assets. Organizations use Form 990-N when their gross receipts are normally $50,000 or less ^[2]. The IRS defines "normally" using an averaging test tied to how long you've been around. A new organization in its first year qualifies if it received $75,000 or less. In years two and three, you average the first two or three years and the number needs to come in at $60,000 or less. From year four on, you average the current year plus the two immediately prior, and that three-year average needs to be $50,000 or less ^[3]. This matters for boosters and PTOs with a lumpy fundraising year, like the year you ran a big gala or got a one-time grant. One high year doesn't automatically bump you into 990-EZ territory if your rolling average still sits under the threshold. Organizations that are required to file the full Form 990 or 990-EZ (generally gross receipts above $50,000, or total assets above $250,000 regardless of receipts, per the 990-EZ instructions) cannot use the e-Postcard instead, even if they'd rather ^[2]. And a handful of organization types are exempt from the annual filing requirement altogether, including churches, their integrated auxiliaries, and conventions or associations of churches ^[4]. Private foundations, regardless of size, file Form 990-PF, not 990-N ^[2].

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

A treasurer keeps the financial books for a club, nonprofit, or association: tracking income and expenses, reconciling the bank account, preparing budgets, and making sure the organization meets its legal filing obligations. In a booster club, PTO, or youth sports league, the treasurer is usually the one volunteer who knows where the EIN letter is filed and whether last year's 990-N actually got submitted. What does a treasurer do in a club, concretely? Day to day, that means depositing checks and cash from fundraisers, paying vendors and reimbursing parents, keeping receipts organized, and giving the board a clear picture of the bank balance at every meeting. What does a club treasurer do that's specific to nonprofit status? File the annual IRS return (990-N, 990-EZ, or 990 depending on size), maintain the state charity registration if required, and keep records clean enough that a new treasurer can take over without a scavenger hunt. What is a treasurer, in the legal sense? Usually it's an officer position defined in the organization's bylaws, with fiduciary duty to the organization: the obligation to act in the group's financial interest, not your own. What do treasurers do wrong most often? They assume someone else is handling the IRS filing, especially after a board turnover, and three years later the group discovers its tax-exempt status is gone. This is exactly the gap a lot of booster clubs fall into. The previous treasurer moved, the new one inherited a bank account and a stack of folders, and nobody checked the IRS filing status. If that's you right now, confirm your organization's exempt status and filing history using the IRS Tax Exempt Organization Search tool before you do anything else ^[1].

When is the 990-N due?

Form 990-N is due by the 15th day of the 5th month after the end of your organization's tax year ^[2]. For an organization on a calendar-year tax year (ending December 31), that's May 15 of the following year. Many booster clubs and PTOs run on a school-year fiscal calendar instead, often July 1 to June 30. If that's your organization, your e-Postcard is due November 15. There's no extension available for Form 990-N specifically, and there's no paper backup option. If the e-Postcard system is down or you're not sure of your exact deadline, the safest move is to file early rather than push to the deadline. The filing system does not accept late returns for a prior period in the way a paper form might; once the window is closed, it's closed, though the IRS does let you file for a prior year's e-Postcard using the current online form if you're catching up ^[5].

How do I file Form 990-N?

You file Form 990-N through the IRS website, not through mail and not through the old Urban Institute portal (that system was retired years ago; the IRS took over e-Postcard filing directly) ^[1]. Before you start, gather: your EIN, your legal organization name exactly as the IRS has it on file, your mailing address, your tax year start and end dates, the name and address of a principal officer, and your website address if you have one. You'll need to register for an IRS online account (or use Login.gov credentials) to access the filing system. First-time filers sometimes get tripped up here, because the system requires you to verify your identity even though the form itself asks almost nothing. Once submitted, you'll get an on-screen confirmation, and you can check back later using the IRS's Tax Exempt Organization Search tool to confirm the filing shows as received ^[1]. Keep a screenshot or PDF of your confirmation for your own records. The IRS doesn't mail you anything back.

What happens if I miss the 990-N deadline?

For a single missed year, generally nothing happens immediately. There's no monetary penalty for filing Form 990-N late, unlike the 990 and 990-EZ, which do carry penalties for late filing ^[2]. The real danger is cumulative. If an organization fails to file the required annual return or notice for three consecutive years, it automatically loses its tax-exempt status, by operation of law, no notice or warning required beyond what the IRS already publishes ^[6]. This applies to 990-N filers exactly the same as it applies to larger organizations filing the full 990. The automatic revocation date is treated as the filing due date of the third missed year, and the IRS publishes revoked organizations on its Automatic Revocation of Exemption List ^[7]. If your booster club or PTO shows up there, donations made to your organization are no longer tax-deductible for the donor going forward, and the organization may owe corporate income tax on its revenue for the period it was not recognized as exempt. This is the scenario a lot of volunteer treasurers walk into cold: three treasurers over five years, nobody filed, and now the group is technically not a 501(c)(3) anymore even though everyone kept running the same bake sales and car washes the whole time.

How do I check if my organization already lost its exemption?

Search your organization's name or EIN on the IRS Tax Exempt Organization Search tool, which lets you check both current exempt status and whether the organization appears on the Automatic Revocation of Exemption List ^{[1] [7]}. If you find your group on the revocation list, don't panic and don't assume the group has to dissolve. Reinstatement is a known, well-worn process. Smaller organizations, generally those eligible to file 990-N or 990-EZ, can often use Streamlined Retroactive Reinstatement (Revenue Procedure 2014-11) if they apply within 15 months of the later of the revocation date or the date the IRS posted the organization to the revocation list, and they haven't previously had their exemption automatically revoked . Streamlined reinstatement means filing the correct application (Form 1023 or Form 1023-EZ for most 501(c)(3) booster clubs and PTOs) and paying the user fee, currently $275 for Form 1023-EZ or $600 for the full Form 1023, according to the IRS fee schedule for exemption applications . Confirm current fees on IRS.gov before you file, since these numbers do change. Organizations outside the 15-month streamlined window can still apply for reinstatement, but the process involves more documentation showing reasonable cause for the multi-year lapse, and reinstatement may only be effective from the postmark date rather than retroactively. That's a heavier lift and worth reading the IRS's own guidance on reinstatement carefully or getting an accountant involved for that specific step, since retroactive relief and its tax consequences vary by situation .

Does a PTO or booster club need to file 990-N even if it's small?

Yes, if the organization is recognized as tax-exempt under Section 501(c) and its gross receipts are normally $50,000 or less, it needs to file Form 990-N annually, regardless of how informal the group feels ^[2]. "We're just parent volunteers" doesn't exempt an organization from the annual filing requirement once it has (or is supposed to have) recognized tax-exempt status and an EIN. A separate, common confusion: having an EIN does not automatically mean an organization is tax-exempt. Plenty of booster clubs got an EIN to open a bank account and never actually applied for 501(c)(3) recognition with Form 1023 or 1023-EZ. If that's your situation, the annual filing requirement (and the automatic revocation risk) doesn't apply, because there's no exemption to revoke. Confirm your actual exempt status with the IRS search tool ^[1] before assuming which filing track you're on. If your group genuinely has never applied for exemption and has been operating as an unincorporated association or informal group, that's a separate project: deciding whether to incorporate, whether to apply for 501(c)(3) or another exempt category, and whether the benefits (tax-deductible donations, grant eligibility, liability protection if paired with incorporation) are worth the paperwork. That's worth a conversation with your state's nonprofit corporation office and, ideally, someone with actual accounting or legal training, since this piece is a reference, not tax or legal advice.

990-N vs 990-EZ vs full 990: what's the difference?

990-N (e-Postcard)	Small exempt orgs	Gross receipts normally $50,000 or less
990-EZ	Mid-size exempt orgs	Gross receipts under $200,000 AND total assets under $500,000
Form 990 (full)	Larger exempt orgs	Gross receipts of $200,000 or more, OR total assets of $500,000 or more
990-PF	Private foundations	All private foundations, regardless of size	A booster club that runs a single big fundraiser and clears $60,000 in gross receipts for the year has crossed out of e-Postcard territory and needs to look at the 990-EZ instead, at least for that year, then reassess against the three-year average going forward. Worth noting: organizations can always choose to file a more detailed form than required. Some treasurers file 990-EZ even when 990-N would technically work, because it creates a more useful paper trail for board handoffs and grant applications. That's a reasonable call if your board has the bandwidth, but it's not free extra effort for no reason: the 990-EZ takes real time to prepare and can carry a late-filing penalty if you commit to it and then miss the deadline, unlike the penalty-free 990-N [2].

The version of the 990 your organization files depends mostly on gross receipts and total assets, not on how the group feels about paperwork. Here's the breakdown the IRS uses ^{[2] [2]}: | Form | Who files it | Key threshold |

What records does a treasurer need to keep for 990-N filing?

Even though Form 990-N itself asks almost nothing about your finances, you still need to actually know your gross receipts to confirm you qualify for it, and you need records ready in case the IRS or a state charity regulator asks for backup. At minimum, keep a running ledger of all income and expenses, bank statements for every account, and a simple year-end summary showing total gross receipts. Gross receipts, for this purpose, generally means total revenue before subtracting any costs or expenses; that includes fundraiser proceeds, membership dues, sponsorships, and grants, per the IRS instructions for figuring gross receipts ^[3]. Don't net out expenses when deciding whether you're under the $50,000 threshold. This is also where a lot of booster clubs get burned during a treasurer handoff: the outgoing treasurer has the numbers in their head or in a personal spreadsheet, and the incoming treasurer has no idea what was filed, when, or whether the organization is even still recognized as exempt. A State-Personalized Treasurer Kit ($99, one-time) is built for exactly this handoff moment: it bundles your state's specific filing calendar, the IRS forms your organization size actually needs, and a simple records checklist so the next treasurer isn't starting from zero.

What if my organization also needs a state charity registration?

Filing Form 990-N satisfies the federal IRS requirement, but it's a separate question from whether your state requires charitable solicitation registration. Many states require nonprofits that solicit donations from residents (which includes most booster club and PTO fundraising) to register annually with the state attorney general's office or a dedicated charity regulator, and that filing has its own deadline, fee, and form, unrelated to the IRS calendar. Requirements vary widely by state: some exempt very small organizations, some tie the threshold to the same gross receipts test as the IRS, and some don't exempt anyone regardless of size. Confirm your specific state's charity registration requirement, threshold, and deadline with your state attorney general's charity office or secretary of state before assuming that filing your 990-N covers you at the state level too. It doesn't.

Frequently asked questions

What is Form 990?

Form 990 is the umbrella name for the annual information return tax-exempt organizations file with the IRS. It comes in several versions (990-N, 990-EZ, full 990, 990-PF) depending on the organization's size and type, per IRS guidance on annual exempt organization returns ^[1]. It reports finances and activities so the IRS and public can see how the organization operates.

What is the 990 tax form used for?

It's used to report an exempt organization's finances, governance, and activities to the IRS annually, confirming the organization still qualifies for tax-exempt status. Despite the name, it's an information return, not a form for calculating income tax owed. Nonprofits generally don't pay income tax on mission-related revenue, but they still must file this annual disclosure ^[1].

What does a treasurer do in a club?

A club treasurer tracks all income and expenses, reconciles the bank account, prepares budgets and financial reports for the board, and handles required filings like the annual IRS 990-N (or 990-EZ/990) and any state charity registration. In practice, they're also the person responsible for making sure the group's tax-exempt status stays active year over year.

What does a treasurer of a club do that a regular member doesn't?

The treasurer has fiduciary responsibility: legal and ethical duty to manage the organization's money in its best interest, not their own. That means signing checks, keeping receipts, filing the IRS annual return, maintaining records for audits or handoffs, and flagging financial problems to the board before they become emergencies.

Who is required to file Form 990-N?

Tax-exempt organizations under Section 501(c) whose gross receipts are normally $50,000 or less must file Form 990-N annually, unless they choose to file a more detailed 990-EZ or full 990 instead, per IRS filing thresholds ^[1][3]. Churches and certain church-affiliated organizations are generally excused from the annual filing requirement altogether ^[5].

When is Form 990-N due each year?

It's due by the 15th day of the 5th month after your organization's tax year ends ^[1]. Calendar-year organizations (year ending December 31) file by May 15. School-year organizations (July 1 to June 30) file by November 15. There's no extension option for this specific form.

What happens if a nonprofit doesn't file 990-N for one year?

Nothing immediate. There's no monetary penalty for one late or missed 990-N filing, unlike the 990-EZ or full 990 ^[1]. The real risk is cumulative: three consecutive missed years trigger automatic revocation of tax-exempt status under federal law, with no advance warning ^[8].

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

Search your organization's name or EIN using the IRS Tax Exempt Organization Search tool, which shows current exempt status and lists organizations on the Automatic Revocation of Exemption List ^[6][9]. If you find your group there, reinstatement (often streamlined for small orgs) is available; it doesn't mean you have to dissolve.

Can I file 990-N late for a prior year?

The IRS e-Postcard system generally lets you file for a prior open tax year using the current online form, but there's no formal 'late filing' extension mechanism the way there might be for the 990-EZ. If you've missed multiple years or aren't sure of your filing history, check your status with the IRS search tool first ^[6][7].

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 and asks only basic identifying information. 990-EZ is for organizations with gross receipts under $200,000 and total assets under $500,000, and requires actual financial statements and program details ^[1][4].

Does a PTO with no paid staff still need to file 990-N?

Yes, if it's recognized as tax-exempt and has gross receipts normally $50,000 or less. Having volunteers only, rather than paid staff, doesn't change the federal filing requirement. What matters is exempt status and gross receipts, not staffing structure ^[1].

How much does it cost to reinstate a revoked nonprofit's tax-exempt status?

As of recent IRS fee schedules, the user fee is $275 for Form 1023-EZ or $600 for the full Form 1023, the applications used for streamlined or standard reinstatement ^[11]. Confirm current fees on IRS.gov before filing, since fee schedules are updated periodically.

Is filing 990-N the same as registering as a charity with my state?

No. Form 990-N is a federal IRS filing only. Many states separately require charitable solicitation registration through the attorney general's office or a state charity regulator, with its own deadlines and fees. Confirm your specific state's requirement directly with that office, since rules vary widely and change over time.
