Form 990: What’s in a tax return for the tax-exempt?

Form 990 is an annual tax return that tax-exempt organizations file with the Internal Revenue Service (IRS) to report their financial details, activities, and governance. It is often called a nonprofit tax return, but its main purpose is public accountability: donors, grantmakers, regulators, and the public can use it to understand how an organization receives and uses money.

• Form 990 is the main tax-exempt annual return for most nonprofit organizations and other tax-exempt organizations.
• The version you need to file—Form 990-N, 990-EZ, 990, or 990-PF—depends on your organization’s annual gross receipts and total assets.
• Most tax-exempt organizations must e-file 990 series returns, and the standard 990 deadline is the 15th day of the fifth month after the fiscal year ends.
• Form 990 is publicly available for at least three years, though some contributor details are protected for most organizations.
• pdfFiller helps teams prepare, complete, review, organize, and share tax forms online before filing through the required IRS e-file process.

Introduction to the tax-exempt annual return

Handling paperwork for a nonprofit organization requires careful attention to detail. One of the most critical documents you will encounter is the IRS Form 990 “Return of Organization Exempt From Income Tax.” The federal government requires this document to track the financial health and operational integrity of tax-exempt organizations.

This form provides the IRS and the general public with a clear view of your organization. It details how you gather revenue, pay your staff, and execute your mission. Most tax-exempt organizations, including charities, private foundations, and nonexempt charitable trusts, must submit this annual return. Doing so proves that your group continues to qualify for its tax exemption under the tax code. Read our recent article about non-profit taxes and tax-exempt organizations to learn more information on this process.

What is Form 990?

People often ask, ” What is the purpose of Form 990?” Simply put, IRS Form 990 is the annual information return for tax-exempt organizations. Unlike standard corporate tax returns, this form does not calculate income tax owed. Instead, it serves as a transparency tool. It shows the IRS that an organization operates in accordance with the rules governing its tax-exempt status.

The form collects data on your organization’s mission, activities, and finances, making this information available to the public. The government requires this transparency from organizations that receive public funds or tax-deductible donations. Form 990 helps ensure these funds support legitimate charitable work by making it harder to hide fraud or other misconduct.

Donors, journalists, researchers, and watchdog groups all use these tax returns to learn about nonprofits. Tools like Nonprofit Explorer make it easy for anyone to search and read filed returns, which helps ensure organizations are held accountable as intended.

Who must file Form 990?

Most tax-exempt organizations must file an annual information return or submit an annual electronic notice unless an exception applies. This requirement applies to many tax-exempt organizations under Section 501(c), certain political organizations, and some nonexempt charitable trusts. Private foundations file Form 990-PF instead of the standard Form 990 or Form 990-EZ.

Here is the basic way to think about who has to file Form 990:

• Small organizations
• Mid-sized organizations
• Larger organizations
• Private foundations

Some organizations, like churches and their affiliates, may be exempt from filing. However, they should confirm the applicable 990 filing requirements with a qualified tax advisor or directly with the IRS.

990 vs. 990-EZ vs. 990-N: Which form to use

Choosing the right Form 990 version to file depends on your nonprofit’s financial standing, specifically its annual gross receipts and the total value of its assets. Use this table as a guide:

What changed for the 2025 tax year (reported in 2026)?

Tax regulations shift frequently, and staying compliant requires keeping up with reporting changes. For the 2025 tax year (which you report in 2026), the IRS expects to implement clearer reporting guidelines. New 2026 initiatives aim to increase transparency, particularly for government grants and contract reporting.

On April 23, 2026, the Treasury Department announced that the IRS plans to revise Form 990. The goal is to improve transparency for government grants, contracts, and fiscal sponsorships involving 501(c)(3) tax-exempt organizations. The Treasury stated these changes are intended to create clearer reporting, better tax administration, and stronger oversight of public money and tax-exempt status. Government grants and government contracts will face tighter scrutiny to ensure public accountability.

The Treasury and the IRS will publish the proposed regulations and allow for a public comment period before finalizing any changes. As they develop the proposal, officials will consider administrative feasibility, proportionality, and the reporting burden on organizations.

What information does Form 990 include?

The full Form 990 is a complex document with a core section and multiple supplementary schedules. The main form covers summary data, program accomplishments, revenue, expenses, balance sheet information, governance, management, disclosure practices, executive compensation, and compliance with other IRS filing requirements.

Common sections include:

• Part I: Summary of mission, revenue, expenses, assets, and key activities.
• Part III: Program service accomplishments, including the organization’s mission and significant activities.
• Part IV: Checklist of required schedules.
• Part VI: Governance, management, and disclosure.
• Part VII: Compensation of officers, directors, trustees, key employees, highest compensated employees, and independent contractors.
• Part VIII: Statement of revenue.
• Part IX: Statement of functional expenses.
• Part X: Balance sheet.
• Part XII: Financial statements and reporting.

Which Form 990 schedules do nonprofits need?

Form 990 schedules provide extra detail when an organization answers “Yes” to certain questions in Part IV. The correct schedules depend on the organization’s activities, tax-exempt status, revenue sources, and transactions. Common schedules include:

• Schedule A: Used by 501(c)(3) organizations to report public charity status and support.
• Schedule B: Reports major contributors to the IRS. Public disclosure rules vary, and many organizations don’t have to publicly disclose contributor information.
• Schedule C: Reports political campaign and lobbying activities.
• Schedule D: Reports supplemental financial statements and assets.
• Schedule G: Reports on fundraising events and professional fundraising services.
• Schedule J: Reports compensation details for certain individuals.
• Schedule O: Used to provide additional explanations for answers on the main form.

You must follow the 990 instructions carefully to determine which schedules apply to your specific operations. Preparing these schedules requires significant data entry. Using a platform like pdfFiller allows you to neatly type your information directly into PDF tax forms, keeping your financial details legible and professional.

Public disclosure requirements

Form 990 is a public document, and tax-exempt organizations are required to make their annual returns and exemption applications available for public inspection and copying. In-person requests must typically be fulfilled immediately, while written requests must be honored within 30 days.

Your publicly available Form 990 must include:

•  The original return
•  Any amended returns
•  All schedules, attachments, and supporting documents filed with the IRS

Returns must be available for a three-year period beginning with the due date, including extensions, or the actual filing date if later.

There are important privacy limits. Generally, tax-exempt organizations don’t have to disclose contributor names and addresses. However, this rule has some exceptions, like for private foundations.

You can reduce copy requests by making your documents widely available online. According to the IRS, this means posting documents on a public website in a format that anyone can access, download, view, and print for free.

Form 990 filing: Where and when to file

The IRS requires you to e-file all 990 forms. Mailing paper returns is no longer an option. The Taxpayer First Act now requires most tax-exempt organizations to file their information returns electronically. This includes Form 990, Form 990-EZ, and Form 990-PF. You must use an authorized IRS e-file provider to submit your annual return.

Form 990 deadline

The standard 990 deadline is the 15th day of the 5th month following the end of your organization’s taxable year. For organizations that follow the standard calendar year (ending December 31), the deadline is May 15. If you need more time, you can request an automatic six-month extension by filing Form 8868 before your original deadline.

What are the penalties for not filing?

Ignoring your nonprofit tax return obligations carries severe consequences. The IRS can assess late-filing penalties for a required return filed late without reasonable cause.

For each day a return is late, the IRS imposes a penalty:

• For organizations with gross receipts under $1,309,500, the penalty is $25 per day, up to a maximum of $13,000 or 5% of gross receipts, whichever is less.
• For organizations with gross receipts over $1,309,500, the penalty increases to $130 per day, with a maximum of $65,000.

Penalties may also apply if you file a paper return instead of e-filing, or if you submit an incomplete or incorrect return.

If an organization fails to file its required return for three consecutive years, the IRS will automatically revoke its tax-exempt status. This is the ultimate penalty for non-compliance. Once revoked, your organization must pay income tax, and donations will no longer be tax-deductible for donors.

Common Form 990 mistakes to avoid

Mistakes on your Form 990 can lead to IRS audits and public scrutiny. Common mistakes you should avoid include:

• Using the wrong tax year: Make sure the tax year on the form matches your organization’s fiscal year.
• Forgetting schedules: Your return is incomplete if you forget to attach required documents like Schedule A or Schedule B.
• Making math errors: Double-check that your balance sheets and revenue statements match.
• Leaving out officer information: You must provide a complete list of current officers, directors, and key employees, including their compensation.
• Leaving required lines blank: If a line requires an answer, enter zero or “N/A” when appropriate instead of leaving it empty.
• Misclassifying revenue: Properly classify revenue between program services, government grants, and public contributions.
• Forgetting public disclosure: Review the public copy before posting, and remove sensitive personal information like Social Security numbers.

Review your 990 instructions multiple times before filing. Using a digital document editor like pdfFiller lets your accounting team collaborate on the form, making it easier to catch errors before final submission.
