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

Last updated 2026-07-24

What is Form 990?

Form 990 is the annual information return the IRS requires from most tax-exempt organizations, including 501(c)(3) charities, booster clubs, and PTOs with recognized exemption. It is not an income tax return in the way a business files one. Exempt organizations generally do not owe federal income tax, so the 990 exists mainly to report finances, activities, and governance to the IRS and the public ^[1]. The IRS says the form's purpose is to "provide the public with financial information about a nonprofit organization" and to help the agency confirm the group is still operating consistent with its exempt purpose ^[1]. Think of it as a mix of a financial statement and an activity report, filed once a year, forever, for as long as your exemption exists. There are four versions, and which one you file depends almost entirely on how much money moved through your group that year. Get the wrong one and you either waste hours on paperwork you didn't need, or worse, you file nothing because you assumed a tiny group like yours doesn't have to. Every exempt org has to file something. ^[990](/articles/treasurer-basics/990) is the general shorthand people use for the whole family of forms.

What is a 990 tax form, exactly, and why does a small club need one?

A 990 tax form is the annual paperwork your booster club, PTO, or youth sports nonprofit files to stay in the IRS's good graces. It's the price of exemption. You don't pay federal tax on dues and fundraiser proceeds, but you do owe the IRS a look at your books every year. Small groups often think that because they never made a dime of taxable profit, they're off the hook. Not true. Filing obligation is based on being a recognized exempt organization (or acting like one under a group exemption), not on whether you owed tax. Even a group with $8,000 in bake sale revenue and a checking account files something, typically the 990-N. The stakes are real. Skip filing for three consecutive years and your exemption is automatically revoked by law, no warning letter required beyond what the IRS already sends. Section 6033(j) of the tax code lays out this three-year rule directly ^[2]. Once revoked, donations to your group are no longer tax-deductible to the giver, and you may owe state-level consequences too, depending on where you're chartered.

Which version of Form 990 does my group file (990-N, EZ, or full 990)?

Gross receipts normally $50,000 or less	Form 990-N (e-postcard)	Filed online only, 8 basic questions
Gross receipts under $200,000 AND total assets under $500,000	Form 990-EZ (or full 990)	Short version optional
Gross receipts $200,000+ OR total assets $500,000+	Form 990 (full)	Required, no shortcut
Private foundations (any size)	Form 990-PF	Always required, regardless of size	"Normally $50,000 or less" is a specific IRS averaging test, not a hard annual cap. The IRS instructions define it using a 1-year, 3-year average, or 4-year average depending on how long the org has existed [3]. A booster club that ran a $70,000 one-time fundraiser but averages $40,000 a year over three years can still file the 990-N. Confirm your specific averaging calculation with the IRS instructions or a qualified preparer before you assume you qualify. Most PTOs and youth sports boosters with a normal annual budget under $50,000 file the 990-n, also called the form-990-n e-postcard. It takes maybe 10 minutes once you have your EIN and a couple of basic figures. Groups that grow, run a big capital campaign, or hold a facility with real assets eventually graduate to the EZ or full 990.

This is a gross receipts and asset size question, not a subjective judgment call. The IRS uses three tiers for organizations other than private foundations ^[3]: | Your situation | Which form | Key threshold |

What does a treasurer do?

A treasurer is the person responsible for a nonprofit's or club's money: tracking it, protecting it, reporting on it, and making sure the group's bank activity matches what the board and members are told. In a booster club or PTO, that usually means one volunteer wearing a lot of hats at once. Day to day, a treasurer does bookkeeping (recording deposits and expenses), reconciles the bank statement monthly, prepares a budget-to-actual report for meetings, and safeguards cash from fundraisers like concessions stands and car washes. Annually, the treasurer handles or hands off the 990 filing, tracks the fiscal year, and keeps records for the next person who takes the job. Good treasurers also build in basic controls: two people counting cash together, a second signer on checks above some threshold, receipts for every reimbursement. None of this is exotic. It's the same discipline a small business bookkeeper uses, scaled down for volunteer hours and a shoebox of receipts instead of accounting software (though decent software helps a lot).

What is a treasurer, and what do treasurers do in a club specifically?

In a club setting, a treasurer is the elected or appointed volunteer who owns the money side of the organization while other officers handle programs, membership, or events. What a treasurer does in a club boils down to five recurring jobs, whether it's a soccer booster club, a PTO, or a hobby association. First, record keeping: every dollar in and out gets logged, ideally in a simple ledger or spreadsheet, tied to receipts or bank statements. Second, reporting: most clubs expect a treasurer's report at every board meeting, showing current balance, recent transactions, and how actual spending compares to the budget the group approved. Third, compliance: this is where the 990 lives, along with any state charitable registration, sales tax exemption renewals, or raffle license paperwork. Fourth, cash handling: concession stands, gate admissions, and raffle ticket sales generate real cash, and a club treasurer sets up (or should set up) a count-and-verify process with two unrelated people present. Fifth, continuity: a treasurer keeps records organized enough that if they get hit by a bus (or, more realistically, just age out when their kid graduates), the next person isn't starting from zero. What does a club treasurer do that's different from a corporate bookkeeper? Mostly scale and volunteer turnover; the skills are the same, the time available is much smaller.

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

A regular club member pays dues, shows up to events, and maybe votes on decisions. A treasurer has fiduciary duties: legal and practical obligations to handle the group's money honestly, transparently, and in the group's interest, not their own. That distinction matters because a treasurer typically has access others don't: bank login credentials, signing authority on checks, sometimes a debit card. With access comes responsibility. Many state nonprofit statutes and a club's own bylaws spell out that officers, including treasurers, owe a duty of care and loyalty to the organization. If your bylaws don't say this explicitly, assume it applies anyway; it's the baseline expectation for anyone controlling shared money. Practically, what does a treasurer of a club do that sets them apart: they're usually the one signature the bank actually recognizes, the person a fundraiser vendor calls for a W-9, and the name on file with the IRS as the organization's contact. That last part matters more than people realize, because IRS notices about a missed 990 filing go to whatever address and contact are on file, which is often an outdated one from three treasurers ago.

What happens if my group misses the Form 990 deadline?

Nothing catastrophic happens after missing one year, but the clock starts. Form 990 series returns are due on the 15th day of the 5th month after your organization's fiscal year ends. For a calendar-year org (fiscal year ending December 31), that's May 15 ^[4]. Miss that date and you can request an automatic extension using Form 8868, but the return still has to get filed eventually. The real danger is the three-year rule. Under Internal Revenue Code Section 6033(j)(1), an organization that fails to file the required 990-series return for three consecutive years automatically loses its tax-exempt status, effective as of the filing due date for the third year ^[2]. The IRS states plainly: "an organization that fails to file for three consecutive years will automatically lose its tax-exempt status" ^[5]. There's no separate revocation notice you get to appeal beforehand; it's automatic by statute. Once revoked, your group shows up on the IRS Auto-Revocation List, donors can no longer deduct gifts to you, and you may need to file Form 1023 or 1023-EZ again to get reinstated, sometimes with retroactive reasonable cause relief if you can show the failure wasn't willful ^[6]. This is a real headache for volunteer-run groups: a PTO that had three treasurers cycle through in three years, each one assuming the last person filed, is a textbook auto-revocation story. If this happens to you, the irs-form-990 instructions and Rev. Proc. 2014-11 procedures cover streamlined reinstatement for small orgs, but confirm current procedures with the IRS before assuming you qualify.

How do I know if my group already lost its exemption?

Check the IRS Tax Exempt Organization Search tool directly. It's free, public, and lets you search by name or EIN to see current exempt status, filed 990s, and whether an organization appears on the Auto-Revocation List ^[7]. This is worth doing even if you're confident the last treasurer handled everything. Volunteer handoffs are messy. Records get lost. A club that hasn't filed anything in three or four years and has no idea if its exemption is intact should check this tool before doing anything else, including opening a new bank account or applying for a grant, both of which typically require proof of active exempt status. If you find your group on the revocation list, don't panic, but don't ignore it either. Reinstatement is a known process, and for small organizations the IRS offers a streamlined retroactive procedure if you apply within 15 months of the revocation date, per Rev. Proc. 2014-11 ^[8]. Past that window, retroactive reinstatement gets harder and you may end up with a gap where the group was technically taxable.

What information actually goes on Form 990 or the 990-N?

The depth of information required scales with which version you file. The 990-N e-postcard asks for eight basic items: your EIN, tax year, legal name and address, any other names the org uses, the name and address of a principal officer, your website if you have one, confirmation that gross receipts are normally $50,000 or less, and a statement if the org has terminated ^[3]. The 990-EZ and full 990 ask for considerably more: a full statement of revenue and expenses by category, a balance sheet, compensation for officers and highest-paid employees, program service accomplishments, and various compliance questions about governance, conflicts of interest, and related-party transactions. The full 990 also has supplemental schedules (Schedule A for public charity status, Schedule B for large donors, and others) depending on your activities. The 990-tax-form family is public record once filed. Anyone can look up a filed 990 or 990-EZ through the IRS's search tool or through sites that republish nonprofit filings, so what you report is genuinely visible to donors, grant makers, and reporters. That's a feature, not a bug, of the transparency the form is designed for.

Do PTOs and youth sports booster clubs actually need to file if they have no paid staff?

Yes. Having no paid staff, no office, and an all-volunteer board doesn't exempt you from filing. The filing requirement is tied to your tax-exempt status and gross receipts, not to whether you employ anyone. A PTO that raises $30,000 a year through a fall carnival and spring book fair, staffed entirely by parent volunteers, still files the 990-N annually if it holds 501(c)(3) status (or operates under a state or national PTO's group exemption, which is common and worth checking). The same goes for a youth soccer booster club that only exists to buy uniforms and pay tournament fees. Where groups actually get this wrong is assuming that because they never applied for exemption in the first place, none of this applies. If your group has never filed Form 1023 or 1023-EZ and has no IRS determination letter, you're not a recognized 501(c)(3) at all, and the 990 filing question is moot until you fix that first step. Many small boosters operate for years assuming exempt status that was never actually granted; check your group's IRS determination letter or exempt status before assuming any of this applies to you.

How do state charity registration and Form 990 interact?

Federal 990 filing and state charitable solicitation registration are two separate systems that often overlap in paperwork but never in authority. Filing your 990 with the IRS does not satisfy state requirements, and registering with your state attorney general's charity office does not satisfy the IRS. Most states with charitable solicitation laws require organizations that solicit donations from the public, including PTOs running a fall fundraiser or booster clubs selling raffle tickets, to register annually with the state attorney general or secretary of state's charity division. Many of these states also require you to attach a copy of your most recently filed 990 or 990-EZ to the state registration renewal. This is one of the more common places small groups slip up: they file the federal 990-N correctly every year but never realized the state also wanted a separate registration. Requirements vary enormously by state, both in whether registration is required at all and in what dollar threshold triggers it. Confirm the current rule with your state's attorney general's charity registration office or equivalent state charity regulator before assuming either exemption or requirement.

What's the difference between a 990 and a regular income tax return?

A regular income tax return (like Form 1120 for a corporation) reports taxable income and calculates tax owed. Form 990 does something different: it's an information return, meaning its primary job is disclosure, not tax calculation. Most 501(c)(3) organizations owe zero federal income tax on program revenue and donations, so there's no tax liability to compute on the main 990 itself. That said, a 990 isn't purely informational if your group has unrelated business income (income from activities not substantially related to your exempt purpose, like renting out a mailing list or running an unrelated retail operation). In that case you may also need Form 990-T to report and pay tax on that specific unrelated income, even though your core activities remain exempt . For most booster clubs and PTOs, this distinction rarely comes up. Concession sales at your own team's games, dues, and typical fundraisers are considered related to your exempt purpose. But if your group starts running something that looks more like a side business (renting your building to unrelated groups for profit, for instance), it's worth a conversation with a tax professional about whether Form 990-T applies.

Building a Form 990 checklist for a new treasurer

If you just inherited the treasurer role and nobody handed you a folder of instructions, here's the minimum checklist worth working through in your first month. First, find the EIN. Every filing traces back to it, and if the old treasurer can't find it, the IRS Tax Exempt Organization Search tool can often locate it by organization name ^[7]. Second, check current exempt status using that same tool, confirming you're not already on the auto-revocation list. Third, figure out your fiscal year end (calendar year is common but not universal for school-affiliated groups) and calculate your filing due date, the 15th day of the 5th month after fiscal year end ^[4]. Fourth, calculate average gross receipts over the relevant period to confirm which 990 version applies. Fifth, if you're filing 990-N, do it directly through the IRS's e-postcard system; there's no cost to file. A state-specific version of this checklist, tailored to your state's charity registration deadlines and forms alongside the federal 990 calendar, is exactly what the $99 one-time State-Personalized Treasurer Kit is built for; it walks a new volunteer treasurer through both federal and state obligations side by side instead of hunting through two separate government websites. Whether you use that or build your own binder, the point is the same: get this written down somewhere durable, because the next treasurer will thank you.

Frequently asked questions

What is Form 990?

Form 990 is the annual information return the IRS requires from most tax-exempt organizations, reporting finances, activities, and governance rather than calculating tax owed. It comes in four versions (990-N, 990-EZ, 990, and 990-PF) depending on an organization's gross receipts and total assets, per IRS filing thresholds ^[3].

What is a 990 tax form used for?

It's used by the IRS and the public to review a nonprofit's finances and confirm it's still operating consistent with its tax-exempt purpose. It also creates a public record; donors and grant makers can look up an organization's filed 990s through the IRS's search tool ^[7].

What is the 990-N and who has to file it?

The 990-N, or e-postcard, is the simplest version, for organizations with gross receipts normally $50,000 or less. It asks eight basic questions and is filed online only, with no paper option and no cost ^[3].

What does a treasurer do in a PTO or booster club?

A treasurer tracks all money in and out, reconciles bank statements, prepares budget reports for meetings, safeguards cash from fundraisers, and handles annual compliance like the 990 filing and any required state charity registration. It's a recurring, year-round role, not a once-a-year tax task.

What happens if a club treasurer never files Form 990?

After three consecutive years of missed filings, the IRS automatically revokes the organization's tax-exempt status under Internal Revenue Code Section 6033(j) ^[2]. Donations stop being tax-deductible, and the group may need to reapply for exemption, sometimes with a streamlined reinstatement process for small organizations ^[8].

How do I know which 990 version my club should file?

Compare your organization's average gross receipts and total assets to IRS thresholds: $50,000 or less for the 990-N, under $200,000 receipts and under $500,000 assets for the 990-EZ option, and above either threshold requires the full Form 990 ^[3]. Private foundations always file Form 990-PF regardless of size.

When is Form 990 due?

The 15th day of the 5th month after your organization's fiscal year ends. For a calendar-year organization, that's May 15 ^[4]. An automatic 6-month extension is available by filing Form 8868 before the original deadline.

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

Yes, if it holds recognized 501(c)(3) status or operates under a group exemption. The filing requirement is based on tax-exempt status and gross receipts, not on whether the organization has employees or paid staff.

Can I check if my organization already lost its tax-exempt status?

Yes, use the IRS Tax Exempt Organization Search tool, which is free and public. Search by name or EIN to see current exempt status, filed returns, and whether the organization appears on the IRS Auto-Revocation List ^[7].

Is Form 990 the same as a state charity registration?

No. Form 990 is a federal filing with the IRS. Most states with charitable solicitation laws separately require annual registration with the state attorney general's charity office, often requiring a copy of the most recent 990 as an attachment. Confirm your state's specific requirement with your state charity regulator.

What is a treasurer, in simple terms?

A treasurer is the officer or volunteer responsible for an organization's money: recording transactions, reporting on the budget, safeguarding cash, and handling annual compliance filings like Form 990. In small clubs, it's usually one volunteer handling all of these duties alone.

What's the difference between Form 990 and Form 990-T?

Form 990 is the standard annual information return most exempt organizations file. Form 990-T is filed separately, and only if the organization has unrelated business income, meaning revenue from activities not substantially related to its exempt purpose ^[9]. Most small booster clubs never need to file it.
