TL;DR
Form 990 is the annual information return most tax-exempt nonprofits file with the IRS. It reports income, spending, salaries, and governance so the IRS and the public can see how a nonprofit uses its money. Skip it three years running and the IRS automatically revokes your tax-exempt status, per Internal Revenue Code section 6033(j) [1].
What is Form 990 used for?
Form 990 is the annual information return that most tax-exempt organizations file with the IRS. It is not a tax bill. Nonprofits generally don't owe income tax on money raised for their exempt purpose, so the 990 isn't calculating what you owe. It's a disclosure document. The IRS uses it to confirm your organization is still doing what it said it would do when it applied for exempt status, and the public (including watchdog sites like GuideStar/Candid and ProPublica's Nonprofit Explorer) uses it to see how you spend donor money. The IRS's own description is direct: "Tax-exempt organizations, nonexempt charitable trusts, and section 527 political organizations file Form 990 to provide the IRS with the information required by section 6033" [1]. That's the legal hook. Section 6033 of the Internal Revenue Code requires most exempt organizations to file an annual return, and Form 990 (or one of its shorter cousins) is how they do it. For a volunteer treasurer, think of it this way: your bank statements tell you what happened in your checking account. Form 990 tells the IRS and the world what happened to the whole organization, program spending, fundraising costs, board members, largest vendors, and whether anyone got paid unusually well. It's the nonprofit equivalent of a small company's annual report, except it's public and free to view.
What is a 990 tax form, exactly?
| 990-N (e-Postcard) | Small orgs | Gross receipts normally $50,000 or less [2] | |
|---|---|---|---|
| 990-EZ | Mid-size orgs | Gross receipts under $200,000 and total assets under $500,000 [3] | |
| 990 (full form) | Larger orgs | Gross receipts $200,000+ or assets $500,000+ [3] | |
| 990-PF | Private foundations | All private foundations, regardless of size [3] | Most booster clubs, PTOs, and small youth sports leagues land in the 990-n bucket. If your group's gross receipts crept over $50,000 this year because of a big fundraiser or a car wash gone extremely well, check the 990-tax-form EZ threshold before you file, because you may have graduated up a form. |
A 990 tax form is an information return, not an income tax return, filed by tax-exempt organizations recognized under Internal Revenue Code section 501(c), most commonly 501(c)(3) charities and 501(c)(4) social welfare groups. It reports revenue, expenses, assets, program accomplishments, and governance practices for the organization's fiscal year. There isn't just one version. The form 990 family has several sizes depending on how much money your group moves: | Form | Who files it | Rough threshold |
What is the 990 used for by the IRS and the public?
The IRS uses Form 990 to monitor whether an organization is still operating consistent with its exempt purpose, whether insiders are getting paid excessively, and whether the group is filing at all. Chronic non-filers get flagged for automatic revocation. But the IRS isn't the only reader. Form 990 is a public document. Under section 6104(d), most exempt organizations must make their three most recent 990s available to anyone who asks, and the IRS itself publishes filed returns [4]. Donors, grant-makers, journalists, and competing nonprofits pull 990s to check overhead ratios, executive pay, and program spending before they write a check or a story. That public visibility matters more than most new treasurers expect. A booster club with sloppy 990 numbers, missing schedules, or wildly inconsistent year-over-year revenue looks bad to a school district vetting whether to keep working with you, or to a parent deciding whether to trust the group with next year's dues. The [990](/articles/treasurer-basics/990) isn't just IRS paperwork; it's your organization's most visible financial record.
What does a treasurer do?
A treasurer is the person responsible for a nonprofit's money: tracking income and expenses, reconciling the bank account, preparing financial reports for the board, and making sure required filings (like Form 990) get done on time. In a volunteer organization, the treasurer is usually the only person who really understands the books, which is both the job and the risk. Core treasurer duties, in roughly the order a new treasurer encounters them: - Open and control the bank account (and make sure it's not still tied to a departed member's personal login)
- Track every deposit and expense, ideally in a simple ledger or basic accounting software
- Reconcile the bank statement against your ledger monthly
- Prepare a budget vs. actual report for board meetings
- File the annual 990-series return, or confirm someone else is
- Keep receipts and records organized for the next treasurer, more than yourself
- Flag anything that smells like a raffle, silent auction, or cash-heavy event to make sure state rules are followed None of that requires an accounting degree. It requires consistency and a habit of writing things down the day they happen, not the week before the annual meeting.
What is a treasurer? What do treasurers do day to day?
A treasurer is an elected or appointed officer, usually unpaid, who acts as the financial custodian of a club, PTO, or booster organization. Day to day, that means less spreadsheet wizardry than people fear and more small, boring habits repeated on schedule. A realistic weekly and monthly rhythm looks like this: log every deposit and payment as it happens (weekly, minimum), reconcile against the bank statement (monthly), report a one-page summary to the board (monthly or per meeting), and file or confirm the annual 990 (yearly, usually within 4.5 months of the fiscal year end for full 990/990-EZ filers, since Form 990 is due the 15th day of the 5th month after the organization's accounting period ends [5]). What trips up new treasurers isn't the math. It's the handoff gaps: the outgoing treasurer who quietly stopped filing two years ago, the PayPal account nobody remembers the password to, the raffle nobody registered with the state. The 990 filing habit and basic cash controls fix most of that if you do them on a calendar instead of by memory.
What does a club treasurer do differently from a corporate treasurer?
A club treasurer (PTO, booster club, youth sports league) has a much smaller, simpler job than a corporate treasurer, but the stakes for getting the basics wrong are arguably higher because there's usually no accounting staff behind you. A corporate treasurer manages cash flow forecasting, debt, investment portfolios, and banking relationships across a large organization, often with a finance team. A club treasurer manages a checking account, maybe a small savings account, a spreadsheet or simple software ledger, and one annual IRS filing. There's no CFO to catch mistakes. That's the whole job and also the whole risk: one person, usually a volunteer, holding the entire financial picture in their head or their laptop. What does a treasurer of a club do that a corporate treasurer never worries about? Cash-handling at bake sales. Concession stand deposits that don't match the register tape. Raffle tickets sold in a school parking lot. Small nonprofits deal in cash far more than large ones, and cash is exactly where controls break down (two people counting together, deposit slips signed by both counters, no single person handling money alone start to finish).
What does a treasurer do in a club that's just starting out, or taking over mid-year?
If you're inheriting the treasurer role mid-year, your first job isn't bookkeeping, it's forensics: find out what actually exists. Get the EIN, get bank statements for the last 12 to 24 months, and check the organization's exempt status directly on the IRS's Tax Exempt Organization Search tool [6]. That single search tells you whether the group is in good standing or already on the auto-revocation list. Next, figure out what's been filed. If the group has gross receipts normally $50,000 or less and has never filed a 990-N, or hasn't filed in a couple of years, that's priority one, because 990-n filings are due every year and the penalty for skipping three straight years isn't a fine, it's losing exempt status automatically [7]. A brand-new club has an easier path but a longer one: apply for an EIN, decide whether to seek formal 501(c)(3) recognition (Form 1023 or the shorter 1023-EZ) or operate informally, and set up a bank account before any money moves through a personal account. Either way, the first 90 days are about establishing the paper trail, not optimizing it.
What happens if a nonprofit doesn't file Form 990?
If a tax-exempt organization fails to file the required 990-series return for three consecutive years, the IRS automatically revokes its tax-exempt status. This isn't a warning-then-fine system. It's automatic and it happens by law under section 6033(j) of the Internal Revenue Code, added by the Pension Protection Act of 2006 [7]. The IRS states it plainly: organizations that don't file "for three consecutive years" automatically lose their tax-exempt status, and "the revocation of the organization's tax-exempt status is effective as of the filing due date of the third year" [7]. That means the clock has already run out by the time the notice shows up. Groups on the list appear in the IRS's Tax Exempt Organizations Revocation List, searchable through the same Tax Exempt Organization Search tool [6]. Revocation isn't cosmetic. It usually means the organization owes corporate income tax retroactively on money that would have been tax-exempt, donors can no longer deduct contributions, and many states pull charitable registration or grant eligibility until reinstatement. Reinstatement generally means filing Form 1023 or 1023-EZ again and paying the filing fee, plus catching up on any missed 990s. Confirm current reinstatement procedures and fees with the IRS before assuming a quick fix is available.
Which organizations don't have to file Form 990?
Not every tax-exempt group is required to file. Churches, their integrated auxiliaries, and conventions or associations of churches are generally exempt from the annual filing requirement . Some government-affiliated organizations and certain very small subordinate organizations covered under a group exemption may also be excused, depending on structure. Almost everyone else with 501(c) status has to file something, even if gross receipts are $0. That surprises a lot of new treasurers: a booster club that raised nothing this year because the team didn't play still owes a 990-n if it's under the $50,000 threshold and holds exempt status. "Nothing happened" is not a valid reason to skip the filing; it just means the e-Postcard takes about ten minutes to complete [2]. If your group has never formally applied for tax-exempt status and doesn't have an IRS determination letter, the 990 filing requirement doesn't automatically apply the same way. But operating without recognized exempt status has its own tax and donor-deductibility complications, so confirm your organization's actual status with the IRS Tax Exempt Organization Search before assuming you're in one bucket or the other [6].
How is Form 990 different from a regular income tax return?
A regular income tax return (like a Form 1040 or corporate 1120) calculates tax owed on income. Form 990 does not calculate tax owed in almost all cases, because the whole point of 501(c) status is that qualifying income isn't taxed. Form 990 is a disclosure and accountability document, not a tax bill. The practical difference for a treasurer: there's no "amount due" line to stress over on a standard 990. What you're actually being graded on is completeness and consistency. Did you report all revenue sources? Did program expenses versus fundraising expenses versus administrative expenses add up sensibly? Did you disclose related-party transactions, like paying a board member's company for event services? Miss those and you're not looking at a tax penalty, you're looking at an IRS inquiry or a credibility problem with donors who pull your return online. One exception worth knowing: unrelated business income (income from an activity regularly carried on that isn't substantially related to your exempt purpose) can trigger actual tax, reported on Form 990-T, filed separately from the 990 series . A concession stand run by volunteers for your own team is usually fine; renting your parking lot out commercially every weekend might not be. Confirm anything that looks like a business activity with the IRS or a tax professional.
What does a treasurer do to prepare for the annual 990 filing?
Preparation is 90 percent of a smooth 990 season, and it happens in the months before the deadline, not the week of. A workable prep checklist: - Reconcile every bank and payment platform account (checking, savings, PayPal, Venmo for Nonprofits) through the fiscal year end
- Total revenue by source: membership dues, event fundraising, sponsorships, grants, raffle proceeds
- Total expenses by category: programs, fundraising costs, admin, any payments to officers or board members
- Pull the prior year's 990 (or the EIN if this is the first filing) and confirm the fiscal year matches what's on file with the IRS
- Check the current gross receipts against the 990n versus 990-EZ versus full 990 thresholds, because a big fundraising year can bump you up a form
- Note any related-party transactions (a board member's business paid for services, for example) since those need disclosure Doing this quarterly instead of once a year turns a stressful spring scramble into a fifteen-minute wrap-up. This is exactly the kind of cadence a irs-form-990 filing calendar, built once for your specific state and fiscal year, is meant to solve; a one-time reference like the $99 State-Personalized Treasurer Kit at /treasurer-kit-builder exists for that reason, though plenty of treasurers build their own version in a shared spreadsheet and that works fine too.
Does a state raffle license or charitable registration replace the need for Form 990?
No. State charitable registration and state raffle licensing are completely separate from the federal Form 990 requirement, and treasurers sometimes conflate the two because both involve reporting money to a government agency. Form 990 goes to the IRS and covers federal tax-exempt status. Charitable solicitation registration goes to your state's Attorney General or Secretary of State office (the exact agency varies by state) and covers your legal right to solicit donations from residents of that state. A raffle license, separately again, covers your legal right to run a specific game of chance and usually comes with its own reporting requirements on how many tickets sold and how prizes were awarded. A group can be fully compliant on Form 990 and still be operating an illegal raffle because it never got a state gaming or charitable gambling permit. Confirm both charitable registration and any raffle-specific licensing requirements with your state's charity regulator or attorney general's office before running a fundraiser that involves chance, because rules and thresholds differ by state and change periodically.
Frequently asked questions
What is Form 990 used for?
Form 990 is the annual information return tax-exempt organizations file with the IRS under Internal Revenue Code section 6033 [2]. It reports income, expenses, program activities, and governance, letting the IRS and the public confirm the organization is operating consistent with its tax-exempt purpose. It's disclosure, not a tax bill.
What is a 990 tax form?
A 990 tax form is one of several IRS information returns (990-N, 990-EZ, 990, or 990-PF) that tax-exempt organizations file annually depending on size. It reports financial activity and governance details rather than calculating tax owed, since most exempt income isn't taxable in the first place [4].
What is the 990?
The 990 is the standard-length IRS annual information return for tax-exempt organizations with gross receipts of $200,000 or more, or total assets of $500,000 or more [4]. Smaller organizations file the shorter 990-EZ or the 990-N e-Postcard instead, based on their gross receipts for the year.
What does a treasurer do?
A treasurer tracks all money in and out of the organization, reconciles the bank account monthly, reports finances to the board, and makes sure required filings like Form 990 happen on time. In small nonprofits, the treasurer is often the only person who fully understands the books.
What is a treasurer?
A treasurer is the officer, usually elected or appointed and typically unpaid in a volunteer nonprofit, responsible for the organization's cash, bank accounts, financial records, budgets, and compliance filings. The title exists across corporations, clubs, PTOs, and booster organizations, but the scope of the job varies enormously by size.
What do treasurers do?
Treasurers record deposits and expenses, reconcile bank statements, prepare budget reports for the board, safeguard cash from fundraisers, and handle or delegate annual filings like the IRS Form 990 series. In smaller clubs, they also often manage the checking account and payment platforms directly.
What a treasurer does in practice, week to week
Week to week, a treasurer logs transactions as they happen, keeps receipts organized, and watches the bank balance against the budget. Monthly, they reconcile the statement and report to the board. Annually, they file the 990 and confirm the organization's exempt status is still active.
What does a treasurer do in a club specifically?
In a club, a treasurer manages dues collection, event fundraising deposits, vendor payments, and the club's bank account, then reports a simple financial summary at meetings. Most club treasurer work is manual bookkeeping and cash-handling discipline rather than complex accounting.
What does a club treasurer do that's different from other officer roles?
Unlike a president or secretary, a club treasurer holds legal and financial exposure: they're usually the signer on the bank account, the person whose name is tied to the EIN in practice, and the one responsible for the annual 990 filing that keeps the group's tax-exempt status alive.
What does a treasurer of a club do if the group has never filed a 990?
First, check the IRS Tax Exempt Organization Search tool to see current status [7]. If the group holds exempt status but never filed, file the missing 990-N or 990-EZ returns as soon as possible; the IRS doesn't fine late 990-N filers, but three consecutive missed years triggers automatic revocation [1] [3].
Does every nonprofit have to file Form 990?
Almost every organization with recognized 501(c) tax-exempt status must file some version of Form 990 annually, even with $0 in revenue. Churches and certain church-affiliated organizations are generally exempt from the requirement [8]. Confirm your specific organization's obligation with the IRS.
What's the difference between Form 990 and Form 990-N?
Form 990-N (the e-Postcard) is the short electronic filing for organizations with gross receipts normally $50,000 or less [3]. The full Form 990 and the mid-size 990-EZ require much more financial and governance detail and apply once an organization crosses those receipt or asset thresholds [4].
What happens if a booster club or PTO doesn't file Form 990 for a few years?
Missing one year usually just means filing late with no separate penalty for 990-N filers. Miss three consecutive years and the IRS automatically revokes tax-exempt status effective the third year's original due date, per Internal Revenue Code section 6033(j) [1], which can trigger back taxes and loss of donor deductibility.
