What to Know About Upcoming Nonprofit Filing Deadlines

If you run a small or mid-sized nonprofit, staying compliant with the IRS does not have to mean filing the full Form 990. Depending on your organization’s size, you may be eligible for a simpler annual filing: Form 990 EZ or Form 990-N, also known as the e-Postcard.

When are the 2026 tax year Form 990-N and 990-EZ deadlines?

The short answer is: it depends on your tax year. Both Form 990-N and Form 990-EZ are generally due by the 15th day of the 5th month after your organization’s fiscal year ends. Most nonprofits operate on a calendar year, so their 2026 tax year ends December 31, 2026, and their initial filing deadline is May 17, 2027 because May 15 falls on a Saturday. Consult this table to find the filing deadline for your organization’s 2026 tax year:

Ending date of tax year	Initial return due date	Extended due date for 990-EZ
December 31, 2026	May 17, 2027 *	November 15, 2027
November 30, 2026	April 15, 2027	October 15, 2027
October 31, 2026	March 15, 2027	September 15, 2027
September 30, 2026	February 16, 2027 *	August 16, 2027 *
August 31, 2026	January 15, 2027	July 15, 2027
July 31, 2026	December 15, 2026	June 15, 2027
June 30, 2026	November 16, 2026 *	May 17, 2027 *
May 31, 2026	October 15, 2026	April 15, 2027
April 30, 2026	September 15, 2026	March 15, 2027

* Adjusted from the 15th because that date falls on a weekend or federal holiday

Note that Form 990-EZ filers can request an automatic six-month extension by filing Form 8868 before the original due date. Form 990-N deadlines cannot be extended, but the IRS does not assess a late-filing penalty for a late e-Postcard unless the organization fails to file required annual returns or notices for three consecutive years.

Penalties for Missing the Form 990-N or 990-EZ Deadline

As the core annual filing for your nonprofit’s tax-exempt status, it’s crucial that you submit the right form on time. The consequences differ depending on whether you file Form 990-N or Form 990-EZ, but missed filings can still create serious compliance risks.

1. Daily penalties for late Form 990-EZ filings

For returns required to be filed in 2027, the IRS may assess a $25-per-day penalty for a late Form 990-EZ, up to the lesser of $13,000 or 5% of the organization’s gross receipts. Organizations with gross receipts exceeding $1,339,500 face a higher penalty of $130 per day, up to $66,500. Penalty amounts are adjusted periodically for inflation.

In this guide, we’ll review one of the most common pitfalls nonprofits encounter: late submission. While this error can impact your organization’s standing, it’s completely avoidable. Let’s explore key filing deadlines for the 2026 tax year and practical strategies for submitting your Form 990-N or Form 990-EZ on time.

2. Potential loss of tax-exempt status

While the aforementioned fines can significantly reduce your fundraising revenue, the biggest threat to your nonprofit’s success is the prospect of losing your tax-exempt status. If you fail to file your annual tax form for three consecutive years, you’ll lose your tax exemption status.

3. Additional fees for reapplying for tax-exempt status

If your nonprofit loses your tax-exempt status, you can apply to reinstate it. However, reinstating your exemption status isn’t free and it's time consuming The user fee for filing a Form 1023 (the main application form) is $600. If you’re eligible to file Form 1023-EZ, that fee is $275. Form 1023-EZ is generally intended for smaller, less complex organizations that meet the IRS eligibility worksheet requirements, including limits on projected gross receipts and total assets.

But still, why would you pay these fees if you don’t absolutely need to? It’s much better and easier to avoid the situation by ensuring that you file your tax forms each year, preferably by the defined deadline.

Other challenges

Besides IRS-enforced penalties, your nonprofit might experience the following adverse effects from missing your Form 990-N or 990-EZ deadline:

Lost supporter trust. Your nonprofit relies on supporter trust to thrive. Losing your 501(c)(3) status can discourage supporters from donating or volunteering again.

Reputational damage. Many nonprofits thrive off of community partnerships with other nonprofits and businesses. However, losing 501(c)(3) status can signal that you’re unreliable and need to improve your management strategies.

Challenges securing funding. Some grant makers or sponsors require up-to-date Form 990 filings to consider nonprofits for funding. And even if they don’t, it can be a red flag when they can’t access your nonprofit’s current IRS filing record.

Increased scrutiny from the IRS. Even after reinstatement, losing tax-exempt status can create extra administrative work, require additional filings, and make future compliance more burdensome for your organization.

All of these challenges can jeopardize your nonprofit’s future, but by filing the correct Form 990-N or Form 990-EZ by the deadline, you can stay compliant and protect your organization’s good standing.

How to Mitigate the Impacts of a Missed Form 990 Deadline

If you submit Form 990-EZ after the deadline, you may still be able to lessen the impact by requesting an abatement of penalties. Make the request as an attachment to Form 990-EZ and answer the following questions:

- What prevented you from requesting an extension before the deadline?
- How can you demonstrate that you weren’t simply being careless and had an extenuating circumstance that made you miss the deadline?
- What steps have been taken to prevent this from happening again in the future?

Be as detailed as possible and include evidence to support your claims. It’s even better if you include supporting documents, such as financial statements and board meeting minutes, just ensure these documents are allowed to be shared publicly.

After you’ve requested penalty relief, submit your Form 990-EZ correctly as soon as possible. For Form 990-N, file the e-Postcard as soon as you realize it was missed. While there is no one-time late-filing penalty for Form 990-N, failing to file required annual returns or notices for three consecutive years can still lead to automatic revocation of tax-exempt status.

How to Meet Your Form 990-N or 990-EZ Deadline

Now that you know how missed filings can affect your organization, it’s important to take steps to make sure it never happens again. Improve your overall approach to nonprofit tax filing with these tips:

Gather information proactively. Saving your work to a month before your deadline can cause undue stress and errors. Avoid this and keep your tax season as efficient as possible by storing and organizing financial documents in a central and secure database throughout the year.
Use an IRS-authorized e-file provider. Form 990-N and Form 990-EZ are filed electronically, and an IRS-authorized e-file provider can streamline the process. The right provider can help you choose the correct form, submit it securely, and keep confirmation records for future reference.
Know when extensions apply. If you file Form 990-EZ and need more time, submit IRS Form 8868 before your original due date to request an automatic six-month extension. Form 990-N cannot be extended, so e-Postcard filers should plan to submit as soon as their tax year closes.

If you continue to miss your deadlines or are unsure which form applies, you might consider working with a nonprofit consultant, accountant, or other financial professional. An IRS-authorized e-file provider can also help eligible organizations file Form 990-N or Form 990-EZ electronically and keep confirmation records.
