Form 990 Filing Requirements: Who Must File & When (2026)

Form 990 filing requirements determine which tax-exempt organizations must file an annual return or notice with the IRS, which Form 990 series form they must file, and when the filing is due.
The form generally depends on the organization’s type, gross receipts, total assets, and whether special filing rules apply.
This is more technically precise

Many nonprofit organizations are unsure about their reporting responsibilities. Some wonder if they need to file Form 990 every year, while others are confused about the difference between Form 990, Form 990-EZ, and Form 990-N.

Understanding these rules helps nonprofits maintain compliance, avoid penalties, and keep their tax-exempt status active. This 2026 guide explains the IRS requirements, filing rules, deadlines, and important steps nonprofits should follow.

Which Form 990 Should You File?

• Private foundation?
  → File Form 990-PF

• Otherwise, gross receipts normally $50,000 or less?
  → File Form 990-N, if eligible

• Gross receipts under $200,000 AND total assets under $500,000?
  → File Form 990-EZ or Form 990

• Gross receipts $200,000 or more OR total assets $500,000 or more?
  → File Form 990

What Is Form 990 and Why Do Nonprofits File It?

Form 990 is an annual information return used by many tax-exempt organizations to report financial, operational, governance, and other information to the IRS. It is not generally an income tax return, although certain tax-exempt organizations may owe tax reported on other returns. Form 990 also provides information that may be available to the public.

Unlike a traditional income tax return, Form 990 is mainly designed for transparency. It allows the IRS, donors, and the public to understand how a nonprofit operates and uses its resources.

A nonprofit annual return usually includes information about:

• Organization details

• Revenue and expenses

• Assets and liabilities

• Mission-related activities

• Leadership and governance

• Compensation information

The IRS uses this information to monitor whether organizations continue meeting the requirements for tax-exempt status.

Who Needs to File Form 990?

One of the most common questions nonprofits ask is: Who needs to file Form 990?

Most organizations exempt from federal income tax under Section 501(a) must generally file an annual Form 990, Form 990-EZ, Form 990-PF, or Form 990-N, unless an exception applies.

Organizations that may have filing responsibilities include:

• Public charities

• Educational organizations

• Certain religious organizations

• Foundations

• Social welfare organizations

• Other tax-exempt entities

However, not every nonprofit files the same form. The correct filing depends on factors such as annual revenue, assets, and organization type.

Important: These thresholds do not apply identically to every exempt organization. Special rules and exceptions apply to certain organizations, including churches, supporting organizations, and other specialized entities.

How Do Nonprofits Know Which Form 990 They Need?

Choosing the correct form is an important part of meeting IRS reporting obligations.

The IRS provides different versions of the Form 990 series based on an organization's size and structure.

Form 990

Form 990 is generally required when an organization does not qualify for Form 990-N or Form 990-EZ, subject to applicable exceptions. An organization generally must file Form 990 if its gross receipts are $200,000 or more or its total assets are $500,000 or more at the end of the tax year.

Form 990-EZ

Form 990-EZ is a shorter version of Form 990 available to certain smaller tax-exempt organizations. Generally, an organization may file Form 990-EZ if its gross receipts are less than $200,000 and its total assets are less than $500,000 at the end of the tax year, provided it is otherwise eligible to use the form.

Form 990-N

Form 990-N, also called the e-Postcard, is generally available to eligible small tax-exempt organizations whose gross receipts are normally $50,000 or less. Instead of filing a detailed Form 990 or Form 990-EZ, eligible organizations submit a short electronic notice containing basic information about the organization.

Form 990-PF

Private foundations generally must file Form 990-PF regardless of their financial size. The form reports charitable distributions, investment income, expenses, assets, and other financial information required by the IRS.

Who Does Not Have to File?

Certain organizations are generally not required to file an annual Form 990-series return. Examples include churches and certain church-affiliated organizations, certain governmental entities, and other organizations specifically excluded under IRS rules.

However, an organization’s classification matters. A nonprofit should not assume that it is exempt from filing simply because it is a religious or charitable organization.

Special Rules for Supporting Organizations

Organizations classified as supporting organizations under Section 509(a)(3) have special Form 990 filing rules. In general, supporting organizations are not eligible to use Form 990-N merely because their gross receipts are normally $50,000 or less. They should review the specific IRS filing requirements applicable to their classification.

Form 990-T

Does a Nonprofit Also Need Form 990-T?

A tax-exempt organization may have to file Form 990-T in addition to its required Form 990, Form 990-EZ, or Form 990-N. Generally, an organization with $1,000 or more of gross income from an unrelated trade or business must file Form 990-T to report unrelated business taxable income, subject to applicable rules.

What Information Does the IRS Require on Form 990?

The IRS Form 990 requirements focus on transparency and accountability.

Organizations may need to report information such as:

Basic Organization Information

This includes:

• Legal name

• Employer Identification Number (EIN)

• Mailing address

• Tax year

• Mission statement

Financial Information

Nonprofits generally report:

• Contributions received

• Grants

• Program service revenue

• Operating expenses

• Assets

• Liabilities

Governance Information

The return may also include information about:

• Board members

• Conflict-of-interest policies

Accurate financial records make the filing process easier and help prevent reporting errors.

Important Form 990 Filing Rules Organizations Should Follow

Following proper filing procedures is essential for nonprofit compliance.

Some important Form 990 filing rules include:

File the Correct Return

A nonprofit should determine whether it needs Form 990, Form 990-EZ, Form 990-N, or another version.

Filing the wrong form can create unnecessary compliance issues.

Maintain Accurate Records

Organizations should keep:

• Donation records

• Expense reports

• Payroll information

• Grant documentation

• Board meeting records

Review Before Submission

Before submitting the return, nonprofits should check:

• Financial numbers

• Required schedules

• Organization details

• Supporting information

Submit on Time

Meeting deadlines helps organizations avoid penalties and possible loss of tax-exempt status.

Form 990 Due Date and 2026 Filing Deadline

The Form 990 due date follows a simple IRS rule:

The return is generally due on the 15th day of the fifth month after the end of the organization's tax year.

For example:

Footnote
November 15, 2026 falls on a Sunday. When the filing deadline falls on a Saturday, Sunday, or legal holiday, the deadline moves to the next business day. The IRS table itself shows November 15, but explicitly says it does not reflect the additional day when the date falls on a weekend/holiday. 

Can Form 990 Be Extended?

Yes. An organization filing Form 990, Form 990-EZ, or Form 990-PF can generally request an automatic six-month extension by filing Form 8868 by the original due date. Form 990-N cannot be extended. 

You can also mention Form 990-T because Form 8868 now covers it as well. 

Nonprofit Tax Filing Requirements: Records to Prepare

Meeting nonprofit tax filing requirements becomes easier when organizations maintain proper records throughout the year.

Before preparing Form 990, nonprofits should organize:

• Income statements

• Expense reports

• Donation records

• Grant information

• Asset records

• Board member details

• Previous filings

Good recordkeeping reduces mistakes and makes annual reporting more efficient.

Common Mistakes When Filing Form 990

Many nonprofit organizations experience problems because of avoidable filing mistakes.

Missing the Filing Deadline

Late filing can result in IRS penalties. The applicable penalty depends on the type and size of the organization and the return involved. Organizations should not assume that filing late without a penalty simply because they had little or no tax liability.

Choosing the Wrong Form

A nonprofit may accidentally submit the wrong version of the Form 990 series.

Inaccurate Financial Information

Reported numbers should match accounting records and financial statements.

Forgetting Required Schedules

Some organizations must include additional schedules based on their activities.

Poor Record Management

Missing documents can delay preparation and increase the risk of errors.

IRS Nonprofit Filing Requirements and Compliance

The IRS nonprofit filing requirements exist to ensure transparency among tax-exempt organizations.

Organizations that fail to submit required annual filings may face consequences, including:

• IRS notices

• Financial penalties

• Automatic revocation of tax-exempt status after failure to file the required annual return or notice for three consecutive years
  

  If an organization required to file a Form 990-series return or Form 990-N fails to do so for three consecutive years, its federal tax-exempt status is generally automatically revoked.
