990-N e-postcard filing: what booster treasurers must know

Last updated 2026-08-14

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

Form 990-N, officially called the e-Postcard, is the shortest annual information return the IRS offers to tax-exempt organizations. If your booster club, PTO, or youth sports league normally brings in $50,000 or less in gross receipts a year, this is almost certainly your filing. The IRS says organizations "whose gross receipts are normally $50,000 or less" are eligible to file the e-Postcard instead of a full Form 990 or 990-EZ ^[1]. The form itself is barely a form. You're not reporting income and expense line items like you would on a 990-EZ. You're confirming eight pieces of basic information: your EIN, tax year, legal name and mailing address, any other names the org uses, the name and address of a principal officer, your website (if you have one), and a confirmation that your gross receipts are still under the threshold ^[1]. If your group is newer or bigger, and gross receipts run above $50,000, you likely need Form 990-EZ or the full Form 990 instead, not the e-Postcard. That's a longer conversation covered in our 990 tax form guide. Some organizations, like churches and their integrated auxiliaries, are excused from 990 filings altogether, but a typical booster club or PTO doesn't get that exception.

What does 'gross receipts normally $50,000 or less' actually mean?

This trips people up constantly. "Normally" doesn't mean last year's number in isolation. The IRS uses a rolling average test depending on how long your organization has existed. For an org in its first tax year, you qualify if you received $75,000 or less. For an org that has existed one to three years, the average of receipts for those years, including the current one, must be $60,000 or less. For an org that has been around three years or more, gross receipts must average $50,000 or less over the immediately preceding three tax years, including the year you're filing for ^[2]. This averaging matters if you had one unusually big fundraiser year (a huge raffle, a one-time golf tournament with a big sponsor) that pushed you temporarily over $50,000. You might still average under the threshold and stay eligible for 990-N. Gross receipts, in IRS terms, means the total amount your organization received from all sources during its tax year, before subtracting any costs or expenses ^[2]. That's a common trap: treasurers net out expenses and report a small "profit" number, when the IRS wants the gross amount that came in the door, ticket sales, concessions, sponsorships, all of it, before you paid for anything.

How do you actually file the 990-N e-Postcard?

You file online, and only online. There's no paper version. The IRS moved the e-Postcard filing system to the Tax Exempt Organization Search page on IRS.gov in 2021, after the old Urban Institute-hosted site retired ^[3]. Here's the process, roughly: go to the IRS Tax Exempt Organization Search tool, choose the e-Postcard filing option, create or sign in to an IRS account, and enter your EIN, tax year, legal name, address, principal officer's name and address, and a confirmation statement about gross receipts ^[1][3]. Most treasurers who've done this before say it takes 10 to 15 minutes once you have your EIN and basic org info handy. A few practical notes: you need your organization's correct EIN on file, not the treasurer's Social Security number. If your booster club has changed its mailing address or officer since last year's filing, update it here. And do this every single year your gross receipts stay under the threshold. There's no reminder postcard mailed to you (ironic, given the name), so mark your calendar.

When is the 990-N due date?

Form 990-N is due by the 15th day of the 5th month after your organization's tax year ends ^[1]. For a group on a calendar tax year (ending December 31), that's May 15 of the following year. If your booster club's fiscal year runs July 1 to June 30, a common setup for school-affiliated groups, your 990-N is due by November 15. Check your organization's IRS determination letter or prior filings to confirm which fiscal year you're actually on; treasurers who inherit the books sometimes assume calendar year when the group has always run July to June. There's no extension available for Form 990-N specifically, and no late fee if you miss one year. That last part sounds like good news, but it's actually the trap. The IRS doesn't fine you for a single missed e-Postcard. The penalty is structural and much worse: automatic revocation after three years running.

What happens if you don't file the 990-N?

Nothing happens after one missed year. Nothing happens after two. The consequence lands on year three. By law, "any organization that fails to file required Form 990 series returns for three consecutive years automatically loses its tax-exempt status" as of the filing due date for the third year ^[4]. This is the Pension Protection Act of 2006 rule, and it applies to 990-N filers exactly the same as it applies to organizations filing the full Form 990. There's no warning letter before this happens, no phone call, no grace period beyond the three years themselves. Once revoked, your organization's name shows up on the IRS Auto-Revocation List, a public database anyone (including sponsors and grantors doing due diligence) can search ^[5]. Donations made after the revocation date are no longer tax-deductible to the donor, since the org is no longer recognized as tax-exempt under IRC 501(c)(3) or whatever subsection applied. Your state may also flag this and take its own action against your charity registration or corporate status. Getting reinstated involves a separate application (Form 1023 or 1023-EZ for many small orgs, sometimes with retroactive reinstatement if you qualify and file within a certain window), and possibly back-filing returns. That process is its own headache and is covered in more depth in guidance from the IRS on streamlined and retroactive reinstatement procedures ^[6]. If your booster club is already on that revocation list, don't try to just file this year's 990-N and hope it fixes things. It won't. You need the reinstatement application.

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

990-N (e-Postcard)	Smallest orgs	Gross receipts normally $50,000 or less [1]
990-EZ	Mid-size orgs	Gross receipts under $200,000 and total assets under $500,000
990 (full form)	Larger orgs	Gross receipts $200,000 or more, or total assets $500,000 or more
990-PF	Private foundations	Filed regardless of size	So 990-N isn't a separate tax form in spirit, it's the smallest, simplest member of the 990 family, built for volunteer-run groups that don't have the budget or staff to prepare a real financial statement every year. For a deeper comparison of these thresholds and what triggers a jump from one form to the next, see our irs form 990 guide.

Form 990 is the IRS's general name for the family of annual information returns tax-exempt organizations file to report their finances, governance, and activities to the public. The IRS describes it as the return most tax-exempt organizations must file annually to "provide the IRS with the information required by section 6033" . There are several versions depending on size: | Form | Who files it | Approximate threshold |

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

A treasurer's core job is keeping accurate track of the organization's money and making sure the group meets its legal and financial obligations, filing tax returns among them. What does a treasurer do day to day? Reconcile the bank account monthly, track income and expenses by fundraiser or program, keep receipts and invoices organized, present a budget report at meetings, and manage cash handling for events like concession stands and raffles. What does a club treasurer do that's specific to a small nonprofit like a booster club or PTO? Beyond bookkeeping, the club treasurer is usually the person responsible for the annual IRS filing, whether that's the 990-N e-Postcard, a 990-EZ, or full 990. This is often the single most consequential thing a volunteer treasurer does each year, because missing it repeatedly can cost the entire organization its tax-exempt status. What does a treasurer of a club do when they first take over the books? Usually the first task is finding the EIN, confirming the group's tax-exempt status is current (search the IRS Tax Exempt Organization Search tool or the Auto-Revocation List), and figuring out which 990 form the group has filed in past years. A surprising number of booster clubs change treasurers every year or two, and the filing history gets lost in the handoff. If you're new to the role, our treasurer-basics hub walks through the full set of first-90-days tasks, and our State-Personalized Treasurer Kit ($99 one-time, see treasurer-kit-builder) builds a filing calendar and checklist specific to your state and org type so this doesn't fall through the cracks again.

What is a 990 tax form used for, beyond just avoiding revocation?

Filing isn't only about staying on the IRS's good side. Form 990 (in whatever version applies) is a public document. Anyone, a parent, a potential sponsor, a grant-making foundation, a journalist, can look up your organization's filings. For 990-N filers specifically, the amount of public detail is thin (it's mostly just confirming the org exists and is under the threshold), but for 990-EZ and full 990 filers, the form discloses officer compensation, program expenses, fundraising costs, and governance policies. Grant makers routinely check an applicant's most recent Form 990 before writing a check. A consistent, on-time filing history is a credibility signal, and an auto-revocation notice on public record is the opposite. There's also a practical local reason to keep filings current: many school districts and athletic conferences require booster clubs to show proof of active 501(c)(3) status before they'll let the group fundraise on school property or use the school's name. A revoked status can shut that down mid-season.

Do you need a paid preparer or software to file 990-N?

No. This is one of the few IRS filings genuinely designed for a volunteer to do alone, with no software purchase and no fee. The e-Postcard is free to file ^[1], and it takes about the same amount of time as filling out a short online survey. Where treasurers do sometimes pay for help is with the harder related tasks: figuring out if the group is even correctly classified as tax-exempt, getting reinstated after auto-revocation, or moving up to a 990-EZ once the group outgrows the $50,000 threshold. Those situations can genuinely benefit from a conversation with a CPA or attorney familiar with nonprofit filings, particularly reinstatement, which has real deadlines and paperwork (Form 1023 or 1023-EZ, user fees, sometimes retroactive relief requests) ^[6]. This article isn't tax or legal advice, and BoosterLedger isn't an accounting firm or law firm. For anything beyond the routine e-Postcard, especially reinstatement after revocation or a jump to a different form, confirm the details with the IRS directly or with a qualified preparer.

What if your booster club has never filed anything with the IRS?

This happens more than you'd think. A booster club forms, gets an EIN, maybe even gets a 501(c)(3) determination letter years ago, and then treasurer turnover means nobody files anything for several years running. First step: search the IRS Tax Exempt Organization Search tool by your EIN or name to see your organization's current status and filing history. If you show up on the Auto-Revocation List, your group's exempt status is gone as of a specific date, and you'll need the reinstatement process, not a simple 990-N. If you're not on that list but also have no 990-N filings on record, you may just be behind, and filing this year's e-Postcard (and confirming past years as best you can) is the right move. Second step: figure out your actual fiscal year. Groups affiliated with schools often run July to June, not calendar year, and using the wrong year throws off your due date calculations. Third: get every officer's contact info and the EIN into one shared document so the next treasurer doesn't inherit the same mess. This is exactly the kind of handoff gap our handoff-and-audits content is built around, and it's worth doing even if your filings are currently in good shape, so the next person isn't starting from zero.

Frequently asked questions

What does a treasurer do?

A treasurer manages an organization's money: tracking income and expenses, reconciling bank accounts, preparing budget reports, and handling required filings like tax returns. For a nonprofit booster club or PTO, that usually includes the annual IRS 990 filing (often the 990-N e-Postcard), plus overseeing cash handling at fundraisers and events.

What is a treasurer?

A treasurer is the officer responsible for an organization's finances: cash, bank accounts, budgets, and financial reporting to the board, members, and outside agencies like the IRS. In a volunteer nonprofit, the treasurer is usually an elected or appointed officer, not a paid staff position, and the role rotates every year or two.

What do treasurers do at a typical monthly meeting?

Most treasurers present a financial report: current bank balance, income and expenses since the last meeting, and any upcoming bills or fundraiser payouts. Many boards also want a comparison against the annual budget, so members can see whether spending is on track. Some treasurers also flag any filing deadlines coming up, including the 990-N.

What is Form 990?

Form 990 is the IRS's annual information return for tax-exempt organizations, required under Internal Revenue Code section 6033. It comes in several versions (990-N, 990-EZ, full 990, 990-PF) depending on the organization's size, with the version determined mainly by gross receipts and total assets.

What does a treasurer do in a club?

In a club setting (booster club, PTO, sports league), the treasurer tracks dues, fundraiser income, concession stand cash, and expenses, then reports on all of it to the board. They also usually handle the club's IRS filing obligations, most commonly the 990-N e-Postcard if gross receipts stay under $50,000 a year.

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

A club treasurer manages volunteer-driven, often cash-heavy income (concessions, raffle tickets, car washes) rather than payroll or invoiced business revenue, and files a nonprofit information return (990-N, 990-EZ, or 990) instead of a business tax return. The stakes are different too: a missed filing risks losing tax-exempt status entirely, more than a penalty.

What is a 990 tax form, exactly?

It's not an income tax return in the traditional sense; tax-exempt organizations generally don't owe federal income tax on their exempt-purpose income. Form 990 is an information return: it reports the organization's finances, activities, and governance to the IRS and, for most versions, to the public.

What is the 990?

"The 990" usually refers informally to the whole family of IRS annual filings for tax-exempt organizations: 990-N, 990-EZ, the full Form 990, and 990-PF for private foundations. Which one applies to your group depends mainly on gross receipts and total assets for the tax year.

What does a treasurer of a club do when taking over mid-year?

First, locate the EIN and confirm the organization's IRS status using the Tax Exempt Organization Search tool. Second, find out which 990 version was last filed and when. Third, check the bank account against the last financial report. Fourth, note the group's actual fiscal year so the next 990-N due date is calculated correctly.

Can a booster club file Form 990-N if it had one big fundraiser year over $50,000?

Possibly yes. The IRS uses an averaging test: for organizations three years or older, gross receipts must average $50,000 or less over the preceding three tax years combined with the current one. One unusually large year doesn't automatically disqualify you if the three-year average stays at or under the threshold.

Is there a fee to file Form 990-N?

No. The IRS e-Postcard is free to file, and it's done entirely online through the IRS Tax Exempt Organization Search portal. There's no paper option and no filing fee, which makes it one of the very few IRS filings with zero cost to the organization.

What happens if a booster club's tax-exempt status gets auto-revoked?

Once auto-revoked for missing three consecutive years of 990 filings, the organization loses tax-exempt status immediately, shows up on the public IRS Auto-Revocation List, and donations made afterward aren't tax-deductible to donors. Reinstatement requires filing a new exemption application (often Form 1023 or 1023-EZ), not simply catching up on the e-Postcard.
