Calendar-Year Nonprofits with an Extension: Your 990-EZ Is Due November 16, 2026
Reviewed · First published · 5 min read
If your nonprofit's accounting year is the calendar year and you filed Form 8868 for your 2025 Form 990-EZ, your extended deadline is close. Six months after the May 15 due date is November 15, 2026. That day is a Sunday, so the return is due Monday, November 16, 2026.
This guide explains how that date is worked out, why it is the last extension you get, and what to do if you miss it.
How the date is worked out
The Form 990-EZ instructions set the due date: the 15th day of the 5th month after the accounting period ends, which is May 15 for a calendar-year filer. They add that if the due date falls on a Saturday, Sunday or legal holiday, you file by the next business day.
Form 8868 gives an automatic six-month extension. The Form 8868 instructions say the extended date you enter cannot be later than 6 months from the original due date.
For a calendar-year organization, that gives:
| Date | |
|---|---|
| Tax year | January 1 to December 31, 2025 |
| Original due date | Friday, May 15, 2026 |
| Six months later | Sunday, November 15, 2026 |
| Extended due date | Monday, November 16, 2026 |

This is a tax year 2025 return
The IRS labels a return by the year the accounting year begins. The 990-EZ instructions say to file the 2025 return for calendar year 2025 and for fiscal years that began in 2025 and ended in 2026. A January to December 2025 year is therefore a 2025 return, filed on the 2025 Form 990-EZ, even though you are filing it in late 2026.
Two more rules from the instructions:
- It has to be e-filed. "If you are filing a 2025 Form 990-EZ, you are required to file electronically."
- Paper doesn't count. An organization required to file electronically that sends a paper return instead is treated as not having filed at all.
See tax year and fiscal year if you're unsure which year you're filing.
There is no second extension
The Form 8868 instructions say a single extension of 6 months is allowed for each type of return for a tax year. November 16 is the end of the line. Two more points from the same instructions:
- An 8868 has to be filed by the original due date. One filed after May 15, 2026 did not extend anything, so if your 8868 was late, the return was due in May.
- Form 8868 cannot extend Form 990-N. If your organization files the e-Postcard instead, its 2025 filing was due May 15, 2026 and is simply late now. There is no penalty for a late 990-N, but file it.

The penalty
The IRS penalty page says the penalty applies when a required return isn't filed by the due date, including any extensions of time. The 2025 Form 990-EZ instructions (General Instruction G) set it at $25 a day, up to the lesser of $13,000 or 5% of the organization's gross receipts for the year. The instructions add that the penalty applies on each day after the due date that the return isn't filed.
The figures change from year to year, so always check the instructions for the year you're filing. The same penalty can apply to a return filed without all the required information. Our late filing penalties page has more.
Reasonable cause
The penalty doesn't apply if the organization shows the late filing was due to reasonable cause. The IRS reasonable cause page gives examples such as:
- fires, natural disasters or civil disturbances;
- not being able to get your records;
- death, serious illness or unavoidable absence;
- system issues that delayed a timely e-filing.
The same page says relying on a tax professional generally isn't enough: you're still responsible for complying even if someone else handles your taxes.
The 990-EZ instructions say that a return not filed by the due date (including any extension) should include a statement giving the reasons it wasn't filed on time. Write it while the facts are fresh: who had the records, when officers changed, what went wrong.
If a penalty notice arrives later, the IRS says you can ask for relief by calling the number on the notice, or in writing with Form 843. 990.tax can't advise on penalty relief; for a large notice, talk to a tax professional. See also filing a late Form 990-EZ.
File as soon as you can
Every day adds to the penalty until the cap, so a late return is still worth filing quickly. Keep the three-year count in mind too: the IRS says organizations that don't file for three consecutive years automatically lose their tax-exempt status. Check yours with our revocation lookup.
Tax year 2025 and 990.tax
To be plain: 990.tax cannot file tax year 2025 returns yet. Tax year 2025 e-filing on 990.tax opens once the IRS approves our tax year 2025 software, and we can't promise a date. See which tax years can I file?
If your 2025 Form 990-EZ is due November 16, don't wait for us. The IRS publishes a list of providers whose software has passed its testing for tax year 2025 exempt organization returns. Use one of them to file on time.
A checklist for this week
- Confirm your 8868 was accepted and that your year ends December 31.
- Gather the 2025 numbers: revenue, expenses, balance sheet and the officers' names.
- E-file by Monday, November 16, 2026.
- If you miss it, file as soon as you can and include a statement of the reasons.
Filing an earlier year with 990.tax
990.tax e-files Form 990-EZ, with Schedules A and O, for tax years 2023 and 2024, plus Form 990-N, Form 8868 and California Form 199. If you're catching up on an earlier year, you answer plain-language questions, add a reasonable cause statement if the return is late, an officer signs online, and the IRS acknowledgement appears in your account. Tax year 2023 can only be e-filed until the IRS's late-December changeover. There is one price per filing (pricing).
