Form 990 Deadline: What To Do Before November 16, 2026

Oct 9

7 min read

Your nonprofit's extended Form 990 is due Monday, November 16, 2026. That is about 5 weeks from today.

This guide is for nonprofits that use a calendar year. It tells you what is due, what late filing costs, and what to do each week until the deadline.

Quick answers

The original due date was May 15, 2026.
If you filed Form 8868 on time, your new due date is November 16, 2026. November 15 is a Sunday, so the deadline moves to Monday.
If you did not file Form 8868 on time, you are already late. File the return now.
Miss 3 years in a row and the IRS takes away your tax exempt status.

Deadlines at a glance

Form 990 is due on the 15th day of the 5th month after your tax year ends. If that day lands on a weekend or holiday, the deadline moves to the next business day.

Your tax year ends	Original due date	Extended due date (Form 8868)
December 31, 2025	May 15, 2026 (passed)	November 16, 2026
March 31, 2026	August 17, 2026 (passed)	February 16, 2027
June 30, 2026	November 16, 2026	May 17, 2027
September 30, 2026	February 16, 2027	August 16, 2027

The dates move because some of the 15ths land on a weekend or a holiday. For example, February 15, 2027 is Presidents Day.

Which form do you file?

The form you file depends on how much money came in and how much your nonprofit owns. "Gross receipts" means all the money that came in during the year, before you subtract any costs.

Your nonprofit	Money that came in	What you own (total assets)	Form
Very small	$50,000 or less	Any amount	Form 990 N (ePostcard)
Small	Under $200,000	Under $500,000	Form 990 EZ
Mid size or larger	$200,000 or more	Any amount	Form 990
Mid size or larger	Any amount	$500,000 or more	Form 990
Private foundation	Any amount	Any amount	Form 990 PF

Two rules to remember:

For Form 990 EZ you must meet both limits. If either one is too high, file the full Form 990.
If your nonprofit made $0, you still must file.

How the extension works

Form 8868 gives you 6 more months to file. You do not have to give a reason.

It only works if you file it by the original due date. For calendar year nonprofits, that date was May 15, 2026. You cannot file it now for the 2025 return.
It covers Forms 990, 990 EZ, 990 PF, and 990 T.
It does not cover Form 990 N. The ePostcard cannot be extended.
It gives you more time to file. It does not give you more time to pay. If you owe tax, it was still due on the original date, and interest grows until you pay.
You only get one extension. There is no second one.

What late filing costs

The IRS charges a penalty for every day your return is late. The amount depends on how much money came in.

Money that came in	Penalty per day	Most you can be charged
$1,309,500 or less	$25	The smaller of $13,000 or 5% of money that came in
More than $1,309,500	$130	$65,000

Two examples

A small nonprofit with $80,000 coming in files 60 days late. 60 days times $25 is $1,500. Its limit is $4,000, so the cost keeps growing if it waits another 100 days.
A larger nonprofit with $2,000,000 coming in files 60 days late. 60 days times $130 is $7,800.

Good to know

The penalty is charged to the nonprofit, not to the board members.
If the IRS sends a written request and you still do not file, a responsible person can be charged $10 per day, up to $6,500.
Form 990 N has no dollar penalty. But a late or missed ePostcard still counts toward the 3 year rule in the next section.
You can ask the IRS to drop the penalty if you had a good reason that was out of your control. "We did not know we had to file" is not a good reason.

Losing your tax exempt status

If you do not file for 3 years in a row, the IRS takes away your tax exempt status. It happens on its own. The IRS does not look at your reasons first.

Here is what happens next:

Your income becomes taxable. You must file Form 1120 and pay federal income tax.
Donors may not be able to deduct gifts made after the date you lost status.
Your name goes on a public list that anyone can search.
You must apply again. The fee is $600 for Form 1023 or $275 for Form 1023 EZ.
Getting your old status back is only possible in limited cases.

Small, volunteer run nonprofits are at the most risk. A treasurer leaves, the new one thinks someone else is filing, and 3 years pass.

You can check your status for free on the IRS Tax Exempt Organization Search tool.

Money from side businesses: Form 990 T

Some nonprofits earn money from things that are not part of their mission. The IRS calls this unrelated business income. If it is more than $1,000 in a year, you must file Form 990 T and pay tax on it.

Common examples

Ads sold in your newsletter or program book
Rent from a building you still owe money on
A business you run that has nothing to do with your mission

Usually not counted

Interest, dividends, and royalties
Rent from property you own free and clear
Work done mostly by volunteers
Sales of donated items

Dates and payments

Form 990 T is due on the same date as Form 990. It can be extended to November 16, 2026, but you file a separate Form 8868 for it.
If you expect to owe $500 or more in tax, you must pay in 4 parts during the year. For calendar year nonprofits, those dates are April 15, June 15, September 15, and December 15.

4 mistakes that cost nonprofits the most

Thinking tax exempt means no filing. Tax exempt means you do not pay income tax on mission income. You still file every year, even with $0 in income.
Missing 3 years in a row. It is easy to miss when the person who did the filing leaves.
Skipping Form 990 T. Many nonprofits do not know they owe tax on ad or side business income.
Forgetting state rules. About 40 states and Washington, D.C. ask nonprofits that raise money to register and file a yearly report. This includes online giving. The due dates are not the same as the federal dates, so keep a separate state calendar.

Your 5 week plan to file before November 16

Aim to file by Friday, November 13. That leaves Monday, November 16 as a safety day if the filing system is slow or a fix is needed. There is no second extension.

Week	Dates	What to do	Who	You are done when

If you are running behind

File the best return you can by November 16. Filing on time and fixing later is cheaper than filing late.
You can send an amended return later to correct mistakes.
Call your preparer today if Week 2 is not done by October 23. A late books close is the most common reason for a missed deadline.

If you never filed Form 8868

You are already late. File the return now. Each day costs $25 or $130, based on the table above.
If your nonprofit qualifies for Form 990 N, file it today. It is free and takes a few minutes.
