IRS Form 990 2026: Who Must File, Deadlines & Penalties – Form 990 is one of the most important annual filings for tax-exempt organizations in the United States. It serves as both an IRS information return and a public transparency document that details your nonprofit’s finances, governance, programs, compensation, and activities.
Whether you run a 501(c)(3) public charity, a private foundation, or another exempt organization, understanding IRS Form 990 requirements helps you stay compliant, avoid penalties, protect your tax-exempt status, and build public trust with donors and grantmakers.
This comprehensive guide covers everything you need to know for the 2026 filing season (primarily 2025 tax year returns), based on the latest official IRS information.
What Is IRS Form 990?
IRS Form 990 (Return of Organization Exempt From Income Tax) is the annual information return that most tax-exempt organizations, nonexempt charitable trusts, and section 527 political organizations must file with the IRS under Internal Revenue Code Section 6033.
Unlike a typical tax return that calculates tax owed, Form 990 reports:
- Mission and program service accomplishments
- Revenue, expenses, and balance sheet information
- Governance practices and policies
- Compensation of officers, directors, key employees, and highest-paid individuals
- Transactions with interested parties and related organizations
- Foreign activities, fundraising, hospitals, schools, and more (via required schedules)
The form (and many of its schedules) is open to public inspection, making it a key tool for donors, grantmakers, journalists, and watchdog groups to evaluate nonprofits.
Note: Private foundations file Form 990-PF instead. Very small organizations may file the simplified Form 990-N (e-Postcard) or Form 990-EZ.
Who Must File Form 990?
Filing requirements depend on your organization’s gross receipts and total assets at the end of the tax year. Here’s the current IRS breakdown:
| Gross Receipts & Assets | Form to File | Notes |
|---|---|---|
| Normally $50,000 or less | Form 990-N (e-Postcard) | Electronic only. Can choose to file full 990 instead. |
| Less than $200,000 AND total assets less than $500,000 | Form 990-EZ or Form 990 | 990-EZ is shorter; many organizations file the full 990 voluntarily for better transparency. |
| $200,000 or more OR total assets $500,000 or more | Form 990 (full form) | Most detailed version with all schedules as applicable. |
| Private foundations (any size) | Form 990-PF | Required regardless of financial size. |
Important exceptions exist for certain organizations, including:
- Churches and certain church-affiliated organizations
- Some governmental units and affiliates
- Very small supporting organizations in specific cases
- Organizations with gross receipts normally $5,000 or less in limited situations
Most 501(c)(3) public charities and many other 501(c) organizations must file one of these forms annually. Filing is required even if your exemption application is still pending.

Form 990 vs 990-EZ vs 990-N vs 990-PF: Key Differences
| Feature | Form 990 (Full) | Form 990-EZ | Form 990-N (e-Postcard) | Form 990-PF |
|---|---|---|---|---|

How to File Form 990 Electronically (Mandatory)
Electronic filing is required for Form 990, 990-EZ, and 990-PF under the Taxpayer First Act for tax years beginning after July 1, 2019. Form 990-N has always been electronic-only.
Key rules:
- E-filing is available only for the current tax year and the two prior tax periods.
- Older returns generally must be paper-filed.
- Use IRS-approved e-file providers or software (many accounting firms and services like Tax990 or others specialize in nonprofit e-filing).
Steps to file:
- Gather financial statements, governance documents, compensation data, and activity details.
- Complete the form and all required schedules.
- Have an authorized officer review and sign (electronic signature).
- E-file through an approved provider before the deadline (or extended deadline).
- Retain a copy and confirmation for your records (minimum 3–7 years recommended).
Key Sections of Form 990 and Required Schedules
The full Form 990 includes these main parts:
- Part I: Summary (mission, revenue, expenses, volunteers)

- Part IV: Checklist of required schedules
- Part VI: Governance, management, and disclosure (policies, board independence, conflicts of interest)
- Part VII: Compensation reporting

Penalties for Late Filing or Non-Filing (2026 Amounts)
Failing to file on time or filing an incomplete return triggers daily penalties (inflation-adjusted for returns due in 2026):
- Smaller organizations (gross receipts ≤ ~$1,309,500): $25 per day, maximum $13,000 or 5% of gross receipts (whichever is less).
- Larger organizations (gross receipts > ~$1,309,500): $130 per day, maximum $65,000.
Additional serious consequences:
- Failure to file for three consecutive years → Automatic revocation of tax-exempt status.
- Failure to e-file when required → Treated as not filing.
- Public inspection violations → Additional daily penalties on responsible persons (up to $10,000 per return in some cases).
Reasonable cause explanations can sometimes abate penalties — document everything and respond promptly to IRS notices.
Public Disclosure Requirements
Form 990 is a public document. Your organization must:
- Make the last three years of Form 990 (and your exemption application) available for public inspection at your principal office during regular business hours.
- Provide copies upon request (you may charge a reasonable fee for copying and postage).
- You can satisfy the copy requirement by posting the exact forms on your website (“widely available”).
Exception: Names and addresses of contributors on Schedule B are generally not required to be disclosed publicly (except for section 527 political organizations).
Failing to comply with public disclosure requests can result in penalties on responsible individuals.
Tips for Accurate and Timely Form 990 Filing
- Start early — gather data throughout the year.
- Reconcile Form 990 numbers with your audited financial statements (if you have an audit).
- Answer every “Yes/No” question accurately and explain on Schedule O where required.
- Review compensation reporting carefully (W-2s, 1099s, and related organization compensation).
- Have your board or audit committee review the final return before filing (document the review process).
- Consider filing the full Form 990 even if you qualify for 990-EZ — it often looks more professional to donors and grantmakers.
- Work with a CPA or tax professional experienced in nonprofits, especially if you have unrelated business income (UBI), hospitals, schools, foreign activities, or complex governance.
