Filing IRS Form 990-N: the plain-English guide for treasurers

Last updated 2026-07-24

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

Form 990-N, nicknamed the "e-Postcard," is the shortest and simplest of the annual information returns the IRS requires from tax-exempt organizations. It exists for one reason: to keep small nonprofits, booster clubs, and PTOs from having to fill out a full tax return just to prove they still exist and still qualify for tax-exempt status. You can file Form 990-N if your organization's gross receipts are normally $50,000 or less. The IRS defines "normally" using an averaging test tied to how long you've been around: organizations in their first tax year qualify if they expect $75,000 or less; organizations in their first two years qualify if the average of the first two years is $75,000 or less; organizations three years or older qualify if the average of the most recent three years is $50,000 or less ^[1]. Most small booster clubs, PTOs, and youth sports parent groups fall well under that threshold. Concession stand revenue, entry fees for a single tournament, small sponsorship checks, spirit wear sales, that's usually the whole budget, and it rarely clears $50,000 in a normal year. One catch people miss constantly: private foundations and section 509(a)(3) supporting organizations cannot file 990-N no matter how small they are ^[1]. If that's not your situation, and you're a garden-variety 501(c)(3) or 501(c)(4) booster or parent group under the receipts threshold, 990-N is almost certainly your form.

What information do I need before I start?

The IRS lists eight things you need on hand before you log in to file ^[2]. Gather these first; the actual filing takes about ten minutes once you have them. 1. Employer Identification Number (EIN), sometimes still called a Tax ID Number 2. Tax year (calendar year or whatever fiscal year your bylaws set) 3. Legal name and mailing address 4. Any other names the organization uses 5. Name and address of a principal officer 6. Website address, if you have one 7. Confirmation that annual gross receipts are normally $50,000 or less 8. A statement if the organization has terminated or is going out of business If you just took over as treasurer and don't know the organization's EIN, check an old bank statement, a prior year's filing, or call the IRS Tax Exempt/Government Entities line. Do not apply for a new EIN; every nonprofit needs exactly one, and using a second one creates a filing mess that's a pain to untangle later.

How do I actually file Form 990-N?

You file entirely online. There's no paper version and no mail-in option. The IRS moved e-Postcard filing to its own system, accessible through the main tax-exempt organizations page on IRS.gov ^[3]. You'll need to create or use an existing IRS account (Login.gov or ID.me credentials) to access the filing system. The process itself is short: log in, search for or confirm your organization by EIN, select the tax year, answer the eight questions above, and submit. You'll get an on-screen confirmation, and the IRS updates its Tax Exempt Organization Search tool within a few weeks to show the filing on record. There is no fee to file 990-N. If a website or service charges you money to submit the e-Postcard itself, that's a red flag; the government filing is free, full stop. Paid help can be legitimate for other things (bookkeeping cleanup, prior-year catch-up filings, reinstatement paperwork) but not for the basic annual e-Postcard.

When is the Form 990-N deadline?

Form 990-N is due by the 15th day of the 5th month after your organization's tax year ends ^[4]. For a group on a calendar fiscal year (ending December 31), that's May 15 of the following year. For a school-year-based booster club running July 1 to June 30, the deadline lands November 15. There's no extension form for 990-N, and there's no late fee for filing it late in a single year. That sounds like good news, and in the short term it is. But the real danger isn't a one-year miss, it's three years in a row.

What happens if I file 990-N late, or miss it entirely?

A single late filing has no penalty attached ^[4]. The IRS doesn't send a bill and doesn't flag your account after one missed year. That's genuinely different from Form 990 or 990-EZ, where late filing penalties can run $20 to $110 per day depending on organization size ^[5]. The real trigger is automatic revocation. Under section 6033(j) of the Internal Revenue Code, any organization required to file an annual return or notice (990, 990-EZ, or 990-N) that fails to do so for three consecutive years automatically loses its tax-exempt status, by operation of law, on the filing due date of the third year ^[6]. The IRS doesn't have discretion here; the statute makes revocation automatic, and no warning letter is legally required first. The IRS publishes an Auto-Revocation List so you can check whether your organization has already been hit. If your booster club or PTO shows up there, donations made to you are no longer tax-deductible to the giver, and you may owe corporate income tax on income you'd normally treat as exempt going forward, until you get reinstated.

How do I fix auto-revocation and get tax-exempt status back?

You apply for reinstatement, and the IRS has a streamlined path for small organizations. If you were eligible to file Form 990-N or Form 990-EZ for each of the years you missed, and you're applying for retroactive reinstatement within 15 months of the revocation date, you generally qualify for Streamlined Retroactive Reinstatement under Revenue Procedure 2014-11 . That process requires filing Form 1023 (or Form 1023-EZ if eligible) with a statement citing the revenue procedure, and reasonable-cause language isn't required the way it is for later applicants. Miss the 15-month window and you'll typically need to show reasonable cause for the missed filings, which is a harder, more document-heavy conversation with the IRS. Form 1023-EZ carries a $275 filing fee as of the current IRS fee schedule; the standard Form 1023 costs $600 . Check the IRS user fee page directly before you file, since these numbers do change. While you're in reinstatement limbo, keep filing your regular 990-N (or whatever form applies) going forward. The IRS process assumes you're getting current, more than clearing old debts.

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

Form 990 is the general name for the family of annual information returns tax-exempt organizations file with the IRS. There are three tiers based on gross receipts and total assets: the full Form 990, the shorter Form 990-EZ, and the e-Postcard, Form 990-N, for the smallest organizations . Form 990 (the long version) requires financial statements, program descriptions, compensation disclosures, and governance questions, and it can run 12+ pages plus schedules. Form 990-EZ is a scaled-down version for organizations with gross receipts under $200,000 and total assets under $500,000 . Form 990-N is just the eight data points listed above, nothing more. Which one you file depends entirely on your gross receipts and assets, not on your organization's mission or size of membership. A booster club with $40,000 in annual concession and spirit-wear revenue files 990-N. The same club, if it starts running a $250,000 capital campaign for new bleachers, would need to step up to full 990 or 990-EZ that year. Check the current thresholds on IRS.gov every year since they can shift.

What is a 990 tax form used for, exactly?

The 990 tax form is not an income tax return in the way a business or individual files one. Tax-exempt organizations generally don't owe income tax on money related to their exempt purpose, so there's no tax bill attached to a 990 filing in most cases. Instead, the 990 series exists so the IRS, state charity regulators, donors, and the public can confirm an organization is still active, still operating within its exempt purpose, and not quietly funneling money to insiders. Because of that public-interest function, most 990 series forms (though not the 990-N e-Postcard data itself in the same searchable format) become public record, and sites like GuideStar/Candid and the IRS's own Tax Exempt Organization Search let anyone look up an organization's filing history. For a small booster club, think of 990-N less as a tax form and more as a proof-of-life check-in with the IRS. Skip it three years running and the IRS assumes you've gone dark.

What does a treasurer do, and how does 990-N fit into the job?

What does a treasurer do? At the core, a treasurer tracks money in, money out, and makes sure the organization's financial obligations, including its IRS filings, get handled on time. In a booster club or PTO, that usually means running the checking account, collecting and depositing cash from fundraisers and concessions, paying vendors and reimbursing volunteers, keeping a simple ledger or spreadsheet, and reporting balances to the board or membership at meetings. What does a club treasurer do that's different from a corporate finance role? Mostly, it's smaller in scale but higher in personal exposure. A volunteer treasurer often signs checks personally, has sole access to online banking, and is the one name the IRS and state charity office have on file. That's exactly why 990-N matters so much to this job specifically: if nobody files it for three years, the treasurer is usually the person who has to explain to the board why the organization suddenly can't accept tax-deductible donations anymore. What does a treasurer do in a club month to month, practically? A rough list: reconcile the bank statement against the ledger every month, hold receipts for every reimbursement, keep a running list of recurring bills and filing deadlines (990-N, state charitable registration renewal, sales tax exemption renewal if applicable), and hand off a clean set of records to the next treasurer. The 990-N deadline is one line on that recurring list, but it's the one with the harshest three-strikes consequence if it's ignored. If you inherited a treasurer role mid-year and don't know the filing history, your first move should be checking the Tax Exempt Organization Search tool for your EIN before anything else. It'll show whether prior filings are current or whether you've already got a problem to fix.

Do state charity registration and raffle rules affect my 990-N filing?

Form 990-N is a federal filing only, submitted to the IRS. It doesn't touch your state obligations, and most states run a completely separate charitable solicitation registration system through the attorney general's office or secretary of state. Many states require nonprofits soliciting donations, running raffles, or holding certain fundraisers to register annually with a state charity office, sometimes referencing your federal 990 filings as supporting documentation. If your booster club or PTO plans a raffle, confirm your state's specific charitable gaming or raffle license requirements with your state's attorney general or gaming control office directly, since rules on permit fees, prize limits, and reporting vary widely by state and change often. Don't assume filing 990-N with the IRS means you're square with your state. They're two different governments asking two different questions, and treasurers who only track the federal side sometimes get blindsided by a state registration lapse.

Common 990-N mistakes new treasurers make

A few patterns show up again and again with volunteer treasurers taking over mid-year. First, applying for a new EIN because nobody can find the old one. This creates duplicate records and confuses the IRS's matching system. Search old bank paperwork or call the IRS before requesting a new number. Second, assuming a small organization is automatically exempt without ever applying. Being a nonprofit under state law and being tax-exempt under IRS code section 501(c)(3) or another 501(c) subsection are two different statuses. If your group never filed Form 1023 or 1023-EZ, you may not actually have federal tax-exempt status to protect, and 990-N wouldn't even be the right question yet. Third, forgetting the fiscal year isn't always calendar year. A club that operates on a school-year budget (July to June) has a 990-N deadline of November 15, not May 15, and missing that distinction leads to filing what looks late when it technically isn't, or the reverse. Fourth, treating a single missed year as a crisis. It isn't. One missed 990-N carries no penalty ^[4]. Two missed years, still no direct penalty, but you're on the clock. Three, and you're auto-revoked with no additional notice required by statute ^[6]. Fifth, losing the paper trail during a treasurer handoff. If the outgoing treasurer doesn't pass along the EIN, login credentials, and filing history, the incoming treasurer starts from zero and often misses the deadline simply from not knowing it exists. If you want a structured way to keep this straight across a treasurer transition, a state-specific packaged reference like the Treasurer Kit ($99 one time) walks through the recurring federal and state deadlines for your specific state, so the information doesn't live only in one departing volunteer's head.

Frequently asked questions

What does a treasurer do?

A treasurer manages an organization's money: tracking income and expenses, reconciling bank statements, paying bills, reimbursing volunteers, reporting balances to the board, and handling required filings like Form 990-N. In a volunteer group, the treasurer is usually the sole person with banking access and the main IRS point of contact.

What is a treasurer?

A treasurer is the officer or volunteer responsible for an organization's finances: collecting money, paying expenses, keeping records, and reporting on the group's financial condition. In booster clubs and PTOs, the treasurer is typically an elected volunteer position, not a paid staff role.

What do treasurers do day to day?

Day to day, treasurers deposit cash from fundraisers, reconcile the checkbook against receipts, pay recurring bills, track upcoming filing deadlines (990-N, state charity renewal), and prepare a simple financial report for board meetings. Most of the job is bookkeeping discipline, not accounting expertise.

What does a treasurer of a club do that's different from a company treasurer?

A club treasurer usually handles smaller dollar amounts but carries more personal exposure: often the only signer on the bank account, the sole IRS contact, and the person responsible for keeping the group's tax-exempt status current by filing Form 990-N or the appropriate 990 series form on time.

What is Form 990?

Form 990 is the general name for the IRS annual information return series for tax-exempt organizations, split into three versions by size: full Form 990, Form 990-EZ, and Form 990-N (the e-Postcard) for organizations with gross receipts normally $50,000 or less.

What is a 990 tax form used for?

It's not an income tax bill; it's an annual disclosure return that lets the IRS, state regulators, and the public confirm a tax-exempt organization is still active and operating within its exempt purpose. Failing to file it for three straight years triggers automatic loss of tax-exempt status under IRC 6033(j).

What is the 990, exactly, in plain terms?

"The 990" is shorthand nonprofit people use for whichever annual IRS return their organization files: full 990, 990-EZ, or 990-N. Which version applies depends on gross receipts and total assets, checked every year against current IRS thresholds.

Who is eligible to file Form 990-N instead of the full 990?

Organizations with gross receipts normally $50,000 or less can file 990-N, using an averaging test based on the org's age (per IRS instructions for Form 990-N). Private foundations and section 509(a)(3) supporting organizations cannot use 990-N regardless of size.

How much does it cost to file Form 990-N?

Filing Form 990-N itself is free through the IRS website. There's no government fee for this filing. If you're paying someone, you're paying for their time gathering information or fixing prior-year problems, not for the filing itself.

What happens if I never filed Form 990-N and I'm not sure how many years I've missed?

Check the IRS Tax Exempt Organization Search tool by your EIN first; it shows filing history and whether you're on the Auto-Revocation List. If you're revoked, look into Streamlined Retroactive Reinstatement under Revenue Procedure 2014-11 if you're within 15 months of the revocation date.

Can I file Form 990-N by mail or on paper?

No. Form 990-N is filed exclusively online through the IRS system; there is no paper version. You'll need an IRS online account to log in and submit it.

Does filing Form 990-N satisfy my state charity registration requirements too?

No. Form 990-N is a federal filing only. Most states run separate charitable solicitation registration, often through the attorney general's office, with their own deadlines and fees. Confirm your specific state's requirements directly with that office.

What's the deadline for Form 990-N?

The 15th day of the 5th month after your organization's tax year ends. Calendar-year organizations (year ending December 31) are due May 15. A group on a July-to-June fiscal year is due November 15.

Is there a penalty for filing Form 990-N late once?

No direct monetary penalty applies to a single late 990-N filing. The real risk is cumulative: failing to file any required return for three consecutive years triggers automatic revocation of tax-exempt status under IRC section 6033(j), with no extra warning required.
