Frequently Asked Questions

When is Form 990 due?
Form 990 (or 990-EZ or 990-N) is due by the 15th day of the 5th month after the end of your fiscal year. For calendar-year organizations, that's May 15. You can request an automatic 6-month extension (Form 8868). Filing late can result in penalties; failing to file for three consecutive years can result in automatic revocation of your tax-exempt status.
Which form do I file—990, 990-EZ, or 990-N?
990-N (e-postcard): gross receipts normally $50,000 or less. 990-EZ: gross receipts less than $200,000 and total assets less than $500,000. Full Form 990: gross receipts $200,000 or more, or total assets $500,000 or more. Certain organizations (e.g. private foundations) must file specific forms. Check the IRS Form 990 instructions for the current year; thresholds and rules can change.
What if we miss the Form 990 deadline?
File as soon as possible. Request an extension (Form 8868) before the due date if you need more time. Penalties apply for late filing; amount depends on organization size and how late. If you've missed three years and received a revocation letter, you may need to reapply for exemption (Form 1023) and possibly pay a fee. Don't ignore missed filings—file and pay any penalties to restore good standing.
Is Form 990 public?
Yes. Form 990 is a public document. The IRS makes exempt organization returns available; many nonprofits also post their 990 on their website or provide it to donors and grantmakers. Ensure all information is accurate and that governance and compensation disclosures are consistent with your policies and board records.
