IRS Form 990-N: the complete e-postcard filing guide for small nonprofits

Last updated 2026-07-24

What is IRS Form 990-N?

Form 990-N is the shortest annual information return the IRS offers for tax-exempt organizations. The agency calls it the e-Postcard because you file it electronically and it asks only eight basic pieces of information, no financials, no schedules, no paper ^[1]. Every tax-exempt organization recognized under Section 501(c) must file some version of the Form 990 series each year to keep its tax-exempt status current. Small groups that normally have gross receipts of $50,000 or less get to use the 990-N instead of the long Form 990 or the shorter Form 990-EZ ^[1]. The 990-N filing takes about 15 minutes and costs nothing. You answer eight questions: your organization's legal name, EIN, mailing address, any other names you use, the name and address of a principal officer, your website URL if you have one, confirmation that your gross receipts are normally $50,000 or less, and confirmation that you are terminating (or checking the box that you are not terminating) ^[1]. The IRS launched the 990-N in 2008 to reduce the filing burden on very small nonprofits. Before that, every exempt organization had to file a full paper return regardless of size. The e-Postcard brought tens of thousands of tiny boosters, PTOs, youth sports leagues, and community groups into compliance who had been skipping the paper forms entirely.

Who must file Form 990-N?

You must file Form 990-N if your organization is tax-exempt under Section 501(c) and your gross receipts are normally $50,000 or less ^[1]. "Normally" means your average gross receipts over the most recent three tax years (including the year you're filing for) are $50,000 or less. Gross receipts include all revenue: dues, donations, fundraiser proceeds, program fees, raffle ticket sales, investment income, everything that comes in ^[2]. Do not subtract expenses. Do not net out cost of goods sold. The IRS wants the total inflow. Most booster clubs, school parent-teacher organizations, small youth sports leagues, neighborhood associations, and volunteer fire departments fall into this category. If you routinely bring in $40,000 a year in fundraisers and dues, you file the 990-N. If one year you hit $55,000 but your three-year average is still under $50,000, you stay on the 990-N for that year ^[1]. You cannot use Form 990-N if you are a private foundation, even if your receipts are tiny. Private foundations must file Form 990-PF ^[1]. Churches and certain church-affiliated organizations are exempt from filing any 990 at all, as are some governmental units ^[1]. If your gross receipts climb above the $50,000 threshold on a three-year rolling average, you graduate to Form 990-EZ (for receipts under $200,000 and assets under $500,000) or the full Form 990 (for larger organizations).

How do you file Form 990-N?

Form 990-N is filed exclusively online at the IRS Tax Exempt Organization Search tool filing portal (irs.gov/charities-non-profits) ^[3]. There is no paper version. You cannot mail it in. Log into the e-Postcard system and create an account if you don't have one. You'll need your organization's Employer Identification Number (EIN) and legal name exactly as it appears in IRS records. The system will reject your filing if the name or EIN doesn't match what the IRS has on file ^[3]. Answer the eight required questions. The system walks you through each one. The principal officer question asks for a name and address; this is usually your club president or board chair, not necessarily the treasurer. The "other names" field is where you list any DBAs ("doing business as" names) your group uses ^[1]. When you reach the termination question, check "No" unless your organization is formally dissolving. Checking "Yes" triggers a termination process and you'll need to file a final return with more detail. After you submit, the IRS emails a confirmation to the address you provided. Print or save that email. The IRS does not mail a paper acknowledgment. Your filing typically shows up in the IRS public database (the Tax Exempt Organization Search tool) within a few weeks, but it can take two months ^[3]. The 990-N is due by the 15th day of the fifth month after your tax year ends ^[2]. Most groups use a calendar year, so their 990-N is due May 15. If your fiscal year ends June 30, your 990-N is due November 15. The IRS grants an automatic six-month extension if you need it, but you must request the extension before the original due date using Form 8868 ^[2].

What is the $50,000 gross receipts threshold?

The IRS sets the Form 990-N eligibility line at $50,000 in gross receipts, calculated as an average over the most recent three years ^[1]. Gross receipts means total income from all sources before you subtract any expenses. For a brand-new organization in its first year, "normally" means your actual receipts that year. If you bring in $35,000 in year one, you file a 990-N for year one. In year two, if you bring in $48,000, your two-year average is $41,500, so you still file a 990-N. In year three, if you bring in $60,000, your three-year average is $47,667, still under $50,000, so you file a 990-N for year three ^[1]. In year four, if you bring in another $60,000, your rolling three-year average (years two, three, four) is $56,000. Now you must file Form 990-EZ or the full Form 990 instead of the 990-N ^[1]. The IRS publishes a gross receipts test worksheet in the instructions for Form 990 and 990-EZ that walks you through the math ^[2]. Most small treasurers can do it in a spreadsheet: add up total revenue for each of the last three years, divide by three, and compare to $50,000. If you're right on the edge, say, a three-year average of $49,800, you can still use the 990-N. The IRS does not round up. But many treasurers in that situation voluntarily file the 990-EZ because it's only three pages and gives donors and grantmakers more confidence in your financial management. The 990-N discloses no financial detail at all, which can make some people nervous when they look you up.

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

Miss your Form 990-N deadline and nothing happens immediately. The IRS does not fine small organizations for a single late 990-N. But miss three consecutive years and the IRS automatically revokes your tax-exempt status ^[4]. The Pension Protection Act of 2006 gave the IRS this authority, and the agency has used it aggressively. The IRS itself has said that since 2011 it has revoked the exempt status of more than 760,000 organizations for failing to file for three consecutive years ^[4]. Most were small groups that either dissolved without formally closing or simply didn't know they had to file. Once revoked, your organization is no longer recognized as tax-exempt. Donations to you are no longer tax-deductible. You may owe taxes on any income you received after the revocation date. Grantmakers, corporate sponsors, and state charity regulators all see the revocation when they look you up, and most will not do business with a revoked organization ^[4]. You can apply for reinstatement, but it takes work. If your gross receipts were under $50,000 in each of the years you missed, you can use a streamlined online reinstatement process and pay a reduced user fee ($275 as of 2024) ^[4]. If your receipts were higher, you must file a full Form 1023 or Form 1023-EZ application and pay the standard user fee (currently $600 or $275 depending on the form) ^[4]. Reinstatement is not automatic; the IRS reviews your application and can deny it. The IRS sends notice letters before it revokes, but many groups miss them because the treasurer turned over, the mailing address changed, or the mail went to an old board member who moved away. The IRS's own guidance describes automatic revocation as occurring by operation of law once an organization "fails to file required Form 990-series returns for three consecutive years" ^[4]. If you discover you've been revoked, start the reinstatement process immediately. Some states also have separate filing requirements for charities that operate or solicit in their state. Missing the federal 990-N does not directly trigger a state penalty, but many states cross-check the IRS database, and a revoked status will disqualify you from state raffle licenses, sales-tax exemptions, and grant eligibility. Confirm your state's rules with your state attorney general or charity registration office ^[5].

What does a treasurer do related to Form 990-N?

The treasurer is usually the person who gathers the numbers for the Form 990-N filing, even though the principal officer (typically the president) is the one whose name goes on the form. The treasurer confirms gross receipts, verifies the EIN, and often logs into the IRS system to enter the data. In a small booster club or PTO, the treasurer does most of the day-to-day financial work: depositing checks, writing checks, keeping the ledger, reconciling the bank account. When filing season arrives, the treasurer pulls the year-end financial reports and calculates whether the organization is still under the $50,000 threshold ^[6]. Many small clubs split duties: the treasurer handles the money and the books, the president or secretary handles official correspondence and filings. In practice, the treasurer usually does the 990-N filing because the treasurer has the financial records and knows how to work through the numbers. The principal officer just needs to review and approve before the treasurer hits submit. A good treasurer keeps a 990-N checklist and sets a calendar reminder three months before the due date. The filing itself takes 15 minutes, but gathering the information, tracking down the correct EIN, confirming the legal name matches IRS records, verifying the mailing address, can take longer if records are messy. The treasurer who stays organized all year makes the 990-N filing painless. Some organizations use a bookkeeper or an accountant to prepare the 990-N. That's fine. The treasurer still reviews the draft to make sure the numbers are right, and the principal officer still signs (electronically) to submit it ^[3]. The IRS holds the organization and its officers responsible for the accuracy of the filing, not the preparer.

What is the difference between Form 990, 990-EZ, and 990-N?

The IRS offers three main annual information returns for tax-exempt organizations, sized to match the organization's receipts and assets ^[2]. Form 990-N (the e-Postcard) is for the smallest groups: gross receipts normally $50,000 or less. It asks eight questions, discloses no financial detail, and takes about 15 minutes to file online ^[1]. Form 990-EZ is the short form for mid-sized organizations: gross receipts under $200,000 and total assets under $500,000. It's a three-page paper or electronic form that requires a statement of revenue, a statement of expenses, and a balance sheet. Most booster clubs and PTOs that outgrow the 990-N file the 990-EZ ^[2]. Form 990 is the full return for larger organizations: gross receipts of $200,000 or more, or total assets of $500,000 or more. It's an 11-page core form plus potentially dozens of additional schedules covering governance, compensation, activities, and related organizations. Large youth sports leagues and school foundations file the full 990 ^[2]. All three forms are annual. All three are due by the 15th day of the fifth month after your fiscal year ends. All three can be extended six months using Form 8868 ^[2]. The 990-N is by far the easiest, which is why it's a relief when your group qualifies. The tradeoff is transparency: the 990-N discloses almost nothing, so donors, grantmakers, and sponsors can't see how you manage money. The 990-EZ and the full 990 are public documents that show revenue sources, expense categories, officer compensation, and program accomplishments. Many organizations voluntarily file a 990-EZ even when they could use the 990-N, just to build public trust. For a detailed look at the full Form 990 and when you must use it, see our guide to IRS Form 990. For a comparison of all three forms, see our article on the 990 tax form options.

How do you calculate gross receipts for Form 990-N eligibility?

Gross receipts include all money your organization receives during the tax year from any source, before subtracting any expenses ^[2]. The IRS wants the total inflow. Start with your year-end financial statement. Add up every revenue line: membership dues, fundraiser proceeds (the gross amount collected, not the net profit), program fees, donations, grants, investment income, raffle ticket sales, sponsorship payments, everything. Do not subtract the cost of the fundraiser, the cost of the program, or any other expense. Do not net out cost of goods sold for a resale shop or concession stand. Just add up the revenue side ^[2]. For most small booster clubs and PTOs, this is straightforward: total deposits to the bank account minus any transfers or loans. If you sold $8,000 in raffle tickets and spent $1,200 on prizes, your gross receipts from the raffle are $8,000. The $1,200 is an expense and does not reduce gross receipts ^[2]. Once you have a single year's gross receipts, calculate the rolling three-year average. Add the current year, the prior year, and the year before that, then divide by three. If your receipts were $42,000 in year one, $48,000 in year two, and $51,000 in year three, your three-year average is $47,000. You still qualify for the 990-N in year three because the average is under $50,000 ^[1]. If your organization is brand new, your "normal" gross receipts are just the actual receipts of your first year. If you formed halfway through a calendar year, your first year might be a short year (six months). The IRS lets you annualize that short year for the threshold test: if you brought in $30,000 in six months, your annualized gross receipts are $60,000, so you would not qualify for the 990-N ^[2]. The gross receipts test is the same whether you are filing a 990-N, a 990-EZ, or a full 990. The IRS publishes a worksheet in the Form 990 instructions (Part I, line 12) that walks you through the calculation for organizations near the thresholds ^[2].

What information does the IRS ask on Form 990-N?

The 990-N asks exactly eight pieces of information ^[1]: 1. Employer Identification Number (EIN). This is your organization's nine-digit federal tax ID. The IRS will reject your filing if the EIN doesn't match its records, so double-check the number on your determination letter. 2. Tax year. Enter the 12-month period your filing covers. Most groups use the calendar year (January 1 to December 31). If you use a fiscal year (for example, July 1 to June 30), enter those dates. 3. Legal name of organization. Use the exact name on your IRS determination letter. If your official name is "Lincoln High School Athletic Booster Club Inc." and you go by "Lincoln Boosters," put the full legal name here and list "Lincoln Boosters" in the "other names" field. 4. Mailing address. The IRS wants a current address where it can reach your organization. If your treasurer's home address is your official address of record, use that. If you have a PO Box, use that. The address must match the IRS records or you may need to update your address separately using Form 8822-B before you can file ^[3]. 5. Other names the organization uses. List any DBAs, abbreviations, or former names. This helps donors and the public find you when they search the IRS database. 6. Name and address of principal officer. This is usually your president or board chair. The IRS wants one person's name, not the whole board. The address can be the officer's home address or the organization's address. 7. Website address. If your club has a website, Facebook page, or other web presence, enter the URL. If you don't have one, leave it blank. The IRS will display this URL in its public search tool, so make sure the page is current. 8. Confirmation of gross receipts and termination status. Check the box confirming your gross receipts are normally $50,000 or less. Check the box indicating whether you are terminating or continuing. If you check "terminating," the IRS will close your file and you'll need to file a final return with more detail ^[1]. That's it. No financial statements, no list of board members, no program descriptions. The IRS publishes every 990-N filing in its Tax Exempt Organization Search tool, so the public can see you filed and see the basic information above, but they cannot see your detailed finances ^[3].

When is Form 990-N due?

Form 990-N is due by the 15th day of the fifth month after your tax year ends ^[2]. For organizations using a calendar year (January 1 to December 31), the deadline is May 15 of the following year. If your fiscal year runs July 1 to June 30, your deadline is November 15. The IRS does not adjust the deadline for weekends or federal holidays the way it does for individual tax returns. If the 15th falls on a Saturday, your deadline is the preceding Friday. If it falls on a Sunday, the deadline is the following Monday ^[2]. You can get an automatic six-month extension by filing Form 8868 (the extension request) before your original due date ^[2]. Form 8868 is filed electronically through the IRS e-file system or by paper mail. The IRS grants the extension automatically; you don't need approval. But you must request it before the original deadline passes. With an extension, a calendar-year organization's 990-N is due by November 15. A July-to-June fiscal-year organization gets until May 15 of the following year. The extension moves only the filing deadline, not the underlying facts. You still report the same 12-month period; you just get more time to complete the paperwork. If you miss the deadline and file late, the IRS does not fine you for the first late 990-N. But if you miss the deadline three years in a row, the IRS automatically revokes your tax-exempt status ^[4]. The revocation happens on the due date of the third year you missed, not the filing date of the return you eventually submit. Most volunteer treasurers set a calendar reminder in March to start gathering information for a May 15 deadline. That gives two months to verify the EIN, confirm the legal name, calculate gross receipts, and handle any surprises (like discovering the mailing address in IRS records is an old board member's house).

Can you amend a filed Form 990-N?

No. The IRS does not allow amendments to Form 990-N ^[3]. If you discover an error after you submit the e-Postcard, you cannot go back and correct it. The 990-N asks only eight questions, none of them financial, so the errors that can happen are usually minor: a typo in the principal officer's name, an outdated mailing address, a forgotten DBA name. The IRS does not consider these errors serious enough to require correction, and the online system does not support amendments ^[3]. If you realize mid-year that you filed a 990-N when you should have filed a 990-EZ or full 990 (because your gross receipts were over the threshold), you can file the correct form late and include a note explaining the error. The IRS will process the correct form and you will not be penalized if you file within a reasonable time of discovering the mistake ^[2]. If you accidentally checked the "terminating" box when your organization is not terminating, contact the IRS Exempt Organizations division immediately at the phone number listed on the IRS Charities & Nonprofits page (irs.gov/charities-non-profits). Explain the error and ask them to correct it in their records ^[3]. They cannot amend the 990-N, but they can update their internal file so your tax-exempt status is not inadvertently closed. The inability to amend is one reason to review your 990-N carefully before you hit submit. Print or save a draft, have a second person (the president or another board member) review the eight answers, and make sure every name, number, and address matches your official IRS determination letter and bank records.

Do you need help preparing your 990-N and keeping IRS filings on track?

Most volunteer treasurers file the 990-N themselves because it's short and the IRS system walks you through it. But if you're new to the treasurer role or your organization was auto-revoked and you're filing for reinstatement, you might want a checklist and a timeline. BoosterLedger's State-Personalized Treasurer Kit ($99 one-time) includes a 990 filing calendar with deadline reminders, a gross-receipts calculator worksheet, and a reinstatement checklist if you need to recover from IRS auto-revocation. The kit is built for volunteer treasurers in booster clubs, PTOs, and youth sports leagues who need real checklists, not generic advice. Build your kit at /treasurer-kit-builder. The 990-N is straightforward once you've done it once. The challenge for most small organizations is remembering to do it every year and making sure the treasurer who takes over next year knows it's due. A simple shared calendar event ("990-N due May 15, start gathering info in March") solves that problem. The filing itself is 15 minutes; the institutional memory is the hard part.

Frequently asked questions

What does a treasurer do?

A treasurer manages an organization's money: depositing revenue, paying bills, keeping the books, reconciling bank accounts, and preparing financial reports for the board. In small nonprofits, the treasurer also calculates gross receipts for IRS filings, gathers information for the annual Form 990-N, and keeps records organized for handoff to the next treasurer.

What is a treasurer?

A treasurer is the board officer responsible for the financial records and accounts of an organization. In booster clubs, PTOs, and youth sports leagues, the treasurer is almost always a volunteer parent or community member who tracks income and expenses, prepares financial statements, and files the annual IRS Form 990 series.

What do treasurers do in a club?

Club treasurers deposit dues and fundraiser revenue, write checks or make electronic payments for expenses, keep a ledger of all transactions, reconcile the bank statement every month, prepare monthly or quarterly financial reports for the board, and file the annual IRS Form 990-N or 990-EZ. They also prepare budgets and help the board plan spending.

What is Form 990?

Form 990 is the annual information return that the IRS requires most tax-exempt organizations to file. There are three versions: the 990-N (e-Postcard) for groups with under $50,000 in gross receipts, the 990-EZ short form for receipts under $200,000, and the full Form 990 for larger organizations. Filing keeps your tax-exempt status active.

What is a 990 tax form?

A 990 tax form is the IRS annual information return for tax-exempt organizations. It is not a tax return in the sense of paying taxes; it is a disclosure form that reports revenue, expenses, programs, and governance. The public can view your 990 online, and the IRS uses it to ensure you are operating as a tax-exempt organization.

What is the 990?

The 990 is shorthand for the IRS Form 990 series: the annual filing required for most tax-exempt organizations. Small groups with gross receipts under $50,000 file the 990-N (e-Postcard), mid-sized groups file the 990-EZ, and larger groups file the full Form 990. Missing the 990 for three years results in automatic revocation of tax-exempt status.

Do all nonprofits have to file Form 990-N?

No. Only tax-exempt organizations with gross receipts normally $50,000 or less file Form 990-N. Organizations with higher receipts file Form 990-EZ or the full Form 990. Churches, some church-affiliated groups, and governmental units are exempt from filing any 990. Private foundations must file Form 990-PF regardless of receipts.

Is there a fee to file Form 990-N?

No. Filing Form 990-N is free. The IRS does not charge a user fee to submit the e-Postcard. If you are filing for reinstatement after being auto-revoked, the IRS charges a reduced user fee (currently $275 for small organizations), but the annual 990-N filing itself costs nothing.

Can you file Form 990-N by mail?

No. Form 990-N can only be filed electronically at the IRS website. There is no paper version. If your organization does not have internet access, you can file from a public library computer or ask a board member to file from home using your organization's EIN and information.

What happens if you file Form 990-N late?

The IRS does not fine you for filing a single late 990-N. But if you miss the deadline three years in a row, the IRS automatically revokes your tax-exempt status. Once revoked, donations are no longer tax-deductible and you must apply for reinstatement. File as soon as you realize you're late to reset the three-year clock.

How far back can you file a Form 990-N?

You can file late 990-Ns for prior years as long as you have not been auto-revoked. If you missed last year, file it now; the IRS system accepts late filings. If you missed two years, file both years to avoid hitting the three-year auto-revocation threshold. If you were already revoked, you must apply for reinstatement instead.

Where do you find your organization's EIN for Form 990-N?

Your Employer Identification Number (EIN) is on your IRS determination letter (the letter that granted you tax-exempt status), your bank account statements, and any prior year IRS filings. If you can't find it, call the IRS Business & Specialty Tax Line at 800-829-4933 and ask them to look up your EIN using your organization's legal name and address.

Can a booster club with $60,000 in revenue file Form 990-N?

It depends on the three-year average. If your gross receipts were $60,000 this year but $40,000 and $42,000 the prior two years, your three-year average is $47,333, so you still qualify for the 990-N. If the three-year average is over $50,000, you must file Form 990-EZ or the full Form 990 instead.

Does Form 990-N show your financials publicly?

No. The 990-N discloses only eight pieces of basic information: your EIN, legal name, mailing address, principal officer, website, and confirmation that receipts are under $50,000. It does not show revenue amounts, expense details, or any financial statements. The public can see that you filed, but not your detailed finances.
