IRS Form 990: what it is and which one your group files

Last updated 2026-07-24

What is Form 990?

Form 990 is the annual information return the IRS requires from most organizations that hold federal tax-exempt status under section 501(c). It is not an income tax return in the way an individual's Form 1040 is. Nonprofits generally don't owe income tax on money raised for their mission, so the 990 exists mostly to show the IRS (and the public) where the money came from and where it went ^[1]. The IRS description is blunt about the purpose: exempt organizations file it to report "revenue, expenses, and changes to net assets" among other things, and the return becomes a public record once filed ^[1]. Anyone can pull a nonprofit's 990 through IRS tools or sites like ProPublica's Nonprofit Explorer and see the treasurer's numbers. For a small booster club or PTO, this usually feels bigger than it is. You're not filling out corporate tax schedules. Most small groups qualify for the electronic postcard version, which takes maybe ten minutes once you know your numbers. Worth saying plainly: there isn't one "990 form." There's a family of them, sized to the organization's revenue. Picking the wrong one, or skipping it entirely because you think you're too small, is the single most common mistake new volunteer treasurers make.

What is the 990 tax form, exactly, and why does a small club need to file it?

Even a booster club that never touches six figures in a year is required to file something with the IRS annually, as long as it holds federal tax-exempt status (typically 501(c)(3) for parent groups and booster clubs, though some fall under 501(c)(4) or other categories). The filing requirement is separate from whether you owe any tax. The IRS states that "most tax-exempt organizations are required to file an annual return" and that failing to file for three consecutive years results in automatic revocation of exempt status ^[2]. That's the sentence every new treasurer needs tattooed on the inside of the filing cabinet. A lot of booster clubs don't even realize they have a standalone EIN and exempt status separate from the school district. If your group has its own EIN (not the school's), you almost certainly have a 990 filing obligation, even if you've never filed before. Skipping it because "we're small" or "we're basically part of the PTO down the hall" is exactly how groups end up on the IRS Form 990 auto-revocation list. The filing deadline is the 15th day of the 5th month after your fiscal year ends. For a calendar-year organization (fiscal year ending December 31), that's May 15 ^[1]. Groups running a school-year fiscal calendar (July to June) usually land on a November 15 deadline instead.

Which version of Form 990 does my booster club or PTO file?

Normally $50,000 or less	any	Form 990-N (e-Postcard)
Less than $200,000	Less than $500,000	Form 990-EZ (or full 990)
$200,000 or more	any	Form 990 (full)
any	$500,000 or more	Form 990 (full)	The IRS defines "normally" using a rolling average for newer or fluctuating organizations, not a strict single-year cutoff, which trips people up. An organization in its first tax year qualifies for the 990-N if it received or planned to receive $75,000 or less [3]. After that, the test looks at averages over one, two, or three years depending on how long the organization has existed [3]. Most booster clubs, small PTOs, and youth sports groups land in the 990-N bracket. A concession stand, a few fundraisers, some uniform sales: that rarely clears $50,000 in a year. But a group running a big annual gala, a large equipment drive, or holding significant reserves can cross into 990-EZ or full 990 territory fast, especially if you count gross revenue from fundraisers before subtracting costs (the IRS generally wants gross, not net, for this threshold test) [3]. If you're not sure which bracket you're in, run the math conservatively. It costs nothing to file the more detailed form if you're borderline, and it costs you your exempt status if you guess wrong on the low side and skip filing.

The version depends almost entirely on gross receipts and total assets, not on how much cash sits in the checking account at any one moment. Here's the breakdown the IRS uses ^[3][4]: | Gross receipts | Total assets | Form required |

What is the 990-N e-Postcard and who can use it?

The 990-N is the simplest version: an eight-item electronic form filed through the IRS website, built for small organizations with gross receipts normally $50,000 or less ^[3]. There's no paper option. You file it online through the IRS's e-Postcard system. The information required is minimal: your EIN, tax year, legal name and address, any other names the organization uses, the name and address of a principal officer, your website if you have one, and confirmation that annual gross receipts are normally $50,000 or less ^[3]. That's it. No financial statements, no program descriptions. The catch: there's no extension available for the 990-N and no late filing penalty for a single missed year, because it's an information notice rather than a full return ^[3]. But miss three years in a row and the automatic revocation rule still applies, penalty or not ^[2]. The lack of an immediate penalty lulls a lot of volunteer treasurers into treating it as optional. It isn't.

What is Form 990-EZ and when is it required instead of the full 990?

Form 990-EZ is the middle-tier option, meant for organizations with gross receipts under $200,000 and total assets under $500,000 ^[4]. It's a four-page form covering revenue, expenses, balance sheet basics, and some program service information, considerably more detail than the postcard but far less than the full return. Organizations in the 990-EZ eligible range can also choose to file the full Form 990 instead if they want, though almost nobody does voluntarily since it's more work for no benefit at that revenue size. Booster clubs running larger annual fundraisers, managing a scholarship fund, or holding a meaningful reserve balance often land here. If your gross receipts test comes out between $50,000 and $200,000, this is very likely your form, and it's worth getting comfortable with well before the deadline since it requires actual bookkeeping detail rather than eight quick fields.

What is the full Form 990 and does a booster club ever need it?

The full Form 990 is a long form, running into the double digits of pages once you add required schedules, and it's meant for organizations with gross receipts of $200,000 or more, or total assets of $500,000 or more ^[4]. It asks for detailed revenue and expense breakdowns, compensation disclosures for key people, governance policy questions, and various supplemental schedules depending on your activities. Most volunteer-run booster clubs and PTOs never touch this version. If yours does, because you're running a large multi-school program, holding substantial facility funds, or managing significant grant money, this is the point where paying an accountant familiar with nonprofit returns stops being optional. The full 990 has enough moving parts (functional expense allocation, related-party questions, public support tests) that a volunteer treasurer working from a spreadsheet on a Saturday afternoon is taking on real risk trying to do it alone. This is also usually the moment a booster club board should be asking whether an independent audit or a paid bookkeeper makes sense, a decision that belongs on the financial controls side of running the organization, more than the tax-filing side.

What happens if a booster club doesn't file Form 990 for a few years?

The IRS is specific here: an organization that fails to file the required return or notice for three consecutive years automatically loses its tax-exempt status on the filing due date of the third year, by operation of law, no warning letter required first ^[2]. Once that happens, the organization has to start paying federal income tax on its revenue (as a taxable entity) and, worse for fundraising, donors' contributions are no longer tax-deductible retroactive to the revocation date. The IRS publishes an Auto-Revocation List and you can search your organization's name or EIN to check status directly ^[5]. Getting reinstated isn't free or instant. Depending on how you qualify, the IRS charges a user fee for reinstatement: the standard Form 1023 application carries a $600 fee, while smaller organizations eligible for the streamlined Form 1023-EZ process pay $275 . Either way, you're also backfilling however many years of missed 990s, which for a volunteer treasurer who just inherited a shoebox of receipts is a genuinely miserable project. The honest move if you suspect your group has been quietly delinquent: check the IRS Tax Exempt Organization Search tool immediately, confirm status, and if you're revoked, start the reinstatement paperwork before doing anything else, including opening new bank accounts or applying for grants that require exempt status proof.

What does a treasurer do? (and why 990 filing sits on their desk)

A treasurer manages an organization's money: tracking income and expenses, keeping the bank account reconciled, reporting balances to the board, and making sure required filings, including the annual 990, get done on time. In a booster club or PTO, the treasurer is usually the only person who knows the organization's full financial picture at any given moment. What does a treasurer do in a club, day to day? Deposit fundraiser proceeds. Pay vendor invoices. Reimburse coaches or parent volunteers for approved purchases. Reconcile the bank statement every month. Present a income and expense summary at board meetings. Keep receipts organized enough that someone else could reconstruct the year if needed. What does a club treasurer do that's less obvious: they're often the one person watching the gross receipts number climb toward a threshold that changes which 990 form the group has to file. They're the one who notices the EIN letter from the IRS got shoved in a drawer two treasurers ago and never opened. Good treasurers build a simple annual calendar with the 990 deadline marked, because volunteer turnover means nobody else is going to remember it. What does a treasurer of a club do that a bookkeeper wouldn't: represent the organization's finances to the board and, often, to parents asking where the money went. That accountability piece, more than the arithmetic, is the actual job.

How do I find out which 990 my organization filed last year, or if it filed at all?

The fastest way is the IRS Tax Exempt Organization Search tool, which lets you look up an organization by name or EIN and see its filing history, exemption status, and whether it's on the automatic revocation list ^[5]. This is the first thing a new treasurer taking over the books should check, before anything else, because it tells you immediately whether you're starting clean or starting in a hole. ProPublica's Nonprofit Explorer also pulls IRS 990 data and often displays actual filed returns as PDFs, which is useful if you want to see exactly what a past treasurer reported, more than that a filing exists. If your organization has never filed and you're not sure it even has proper 501(c)(3) status versus just operating under a school district's umbrella, that's a separate and more foundational question than which 990 to file. It's worth confirming your organization's actual exempt status and EIN situation with the IRS directly before assuming any particular form applies.

Does a booster club or PTO need an accountant to file Form 990?

For the 990-N postcard, no. It's designed for a volunteer to complete without professional help; the IRS built it as an eight-field online form specifically so tiny organizations wouldn't need to hire anyone ^[3]. For 990-EZ, plenty of treasurers file it themselves using IRS instructions, especially if the group's finances are simple (one bank account, a handful of fundraisers, no investments or related organizations). It helps to have a set of books that were kept cleanly all year, which is really a financial controls problem more than a tax problem. For the full Form 990, most volunteer boards are better off paying a nonprofit-experienced preparer, at least for the first filing, so someone can set up the right categories and schedules correctly. Getting it wrong doesn't usually trigger an audit by itself, but it does create a public document with errors that donors, school administrators, or a state charity regulator might eventually read. None of this is tax or legal advice, and every organization's situation differs enough (state law, bylaws, funding sources) that confirming your specific requirements with the IRS and, where relevant, your state charity office is the responsible move before you file anything for the first time.

Does Form 990 replace state charity registration or state tax filings?

No. Form 990 is a federal filing with the IRS. Most states with charitable solicitation laws require a separate annual registration or renewal, often (but not always) accepting a copy of your 990 as part of that state filing. These are two different regulators with two different deadlines and two different sets of paperwork. If your booster club solicits donations or runs raffles, check with your state's charity registration office or attorney general's office directly, since requirements vary widely and change periodically. This falls more under raffles by state territory than federal tax filing, but the two obligations often land on a treasurer's desk in the same season, which is exactly when things get missed. Confirm both sets of requirements with the IRS and your state charity office rather than assuming a federal filing covers you at the state level, or vice versa.

A realistic first-year checklist for a new booster club or PTO treasurer

Taking over the books mid-year, or right after a treasurer transition with a thin handoff, is common and stressful. A short, honest checklist beats a long anxious one. First, find the EIN. It should be on old bank statements, old 990 filings, or the original IRS determination letter. Second, check the IRS Tax Exempt Organization Search tool for current status and the automatic revocation list ^[5]. Third, calculate last year's gross receipts to figure out which 990 version applies going forward. Fourth, mark the actual deadline on a real calendar (the 15th day of the 5th month after fiscal year end) ^[1], not a vague "sometime in spring" note. Fifth, if the group has been filing 990-N successfully, just keep doing that every year without drama; it's genuinely quick. Sixth, if you find gaps, missing years, unclear EIN status, or revoked exemption, deal with that before applying for any new grants or opening new accounts that require proof of exempt status. A lot of new treasurers try to build this system from scratch under deadline pressure, which is where a pre-built, state-specific reference genuinely saves a weekend. That's the whole idea behind BoosterLedger's $99 one-time State-Personalized Treasurer Kit: a starting structure for filings, deadlines, and recordkeeping so you're not reconstructing the wheel from a shoebox of receipts in April.

Frequently asked questions

What is Form 990?

Form 990 is the annual information return the IRS requires from most tax-exempt organizations, reporting revenue, expenses, and other activity. It's not an income tax bill; it's a public disclosure document. Which version applies (990-N, 990-EZ, or full 990) depends on the organization's gross receipts and total assets for the year ^[2][3].

What is the 990 tax form used for?

It's used by the IRS and the public to see how a tax-exempt organization raises and spends money, who runs it, and whether it's still operating consistent with its exempt purpose. Once filed, the 990 becomes a public record, viewable through IRS tools or sites like ProPublica's Nonprofit Explorer.

What does a treasurer do?

A treasurer tracks all incoming and outgoing money, reconciles bank accounts, reports finances to the board, and handles required tax filings like Form 990. In a booster club or PTO, they're usually the single point of financial accountability for the entire organization.

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

Not much differs structurally, but club treasurers (booster clubs, PTOs, youth sports groups) often handle smaller, more irregular income (concession stands, raffles, uniform sales) and face frequent volunteer turnover, which makes clean recordkeeping and clear handoff documents especially important.

What is the 990-N e-Postcard?

The 990-N is an eight-item electronic filing for tax-exempt organizations with gross receipts normally $50,000 or less. It's filed online only through the IRS website, asks for basic identifying information, and takes most treasurers under fifteen minutes once they have their EIN handy ^[3].

Does a small booster club really have to file anything with the IRS?

Yes, if it holds its own federal tax-exempt status with its own EIN. Even organizations with minimal income must file at least the 990-N annually. Skipping it isn't a gray area; the IRS automatically revokes exempt status after three consecutive missed years ^[1].

What happens if my organization missed three years of 990 filings?

Your tax-exempt status is automatically revoked as of the filing due date of the third missed year, with no separate notice required by law ^[1]. You'd need to apply for reinstatement, generally paying a $600 or $275 IRS user fee depending on which application form you qualify to use ^[7].

How do I know which 990 form applies to my organization?

Check your gross receipts and total assets for the year. Under $50,000 gross receipts normally means 990-N; under $200,000 gross receipts and under $500,000 total assets means 990-EZ (or full 990 if you choose); above either of those thresholds requires the full Form 990 ^[3][4].

Is Form 990 the same as a state charity registration?

No. Form 990 is filed with the IRS federally. Most states with charitable solicitation laws require a separate state registration or renewal, sometimes using your 990 as supporting documentation. Confirm your specific state's requirements with your state charity office or attorney general directly.

Can a volunteer treasurer file Form 990 without an accountant?

For 990-N, yes, it's built for exactly that. For 990-EZ, many volunteers manage it themselves with clean books and IRS instructions. For the full Form 990, most small nonprofits are better off hiring a preparer experienced with nonprofit filings, given the added schedules and disclosures involved.

What is a treasurer of a club responsible for besides taxes?

Beyond 990 filings, a club treasurer manages bank reconciliation, expense approvals and reimbursements, fundraiser income tracking, board financial reporting, and maintaining records clean enough for the next treasurer or an outside reviewer to follow without confusion.

Where can I check if my nonprofit's tax-exempt status was revoked?

Use the IRS Tax Exempt Organization Search tool, which lists exemption status, filing history, and includes the automatic revocation list searchable by organization name or EIN. This should be the first check for any new treasurer taking over an organization's books ^[6].

When is the Form 990 deadline?

The 15th day of the 5th month after your organization's fiscal year ends. For a calendar-year filer (year ending December 31), that's May 15. Groups on a school-year fiscal calendar (July to June) typically face a November 15 deadline instead ^[2].
