IRS filing timeline

When is Form 1023 due?

The key window is generally 27 months after the end of the month in which the organization was legally formed. Filing within that window can preserve an approved exemption date back to formation. Filing later is usually still possible, but the effective date normally changes.

This is not an absolute last day to apply. The 27-month rule primarily affects the effective date of federal tax-exempt recognition. A late organization can generally still submit an application, but it may lose recognition back to its formation date.

Planning estimate only. Confirm the legal formation date, current IRS instructions, eligibility, and any special facts before filing.

How the IRS counts the 27 months

The IRS starts with the end of the month in which the organization was legally formed, then counts 27 months. For example, an organization legally formed on January 15, 2026 generally reaches the end of its 27-month window on April 30, 2028.

For a corporation, the formation date is generally the date the state authority filed or approved the Articles—not the first board meeting, EIN date, bank-account date, or the day the founder first had the idea.

What timely filing changes

Filing timingGeneral result if approved
Within 27 months after the end of the formation monthExempt status generally takes effect on the legal formation date.
After the 27-month windowExempt status generally takes effect on the application submission date.
Late filing with an earlier-date requestThe full Form 1023 and Schedule E are used to request relief; approval is not automatic.

If the organization is already late

  1. Do not assume the organization can no longer apply. Determine the correct current filing route.
  2. Use the full Form 1023 for an earlier-date request. The Form 1023-EZ instructions say a late organization seeking an effective date earlier than submission must file the full Form 1023.
  3. Complete Schedule E. Explain the late filing and provide the information requested for the effective-date determination.
  4. Understand the relief standard. The IRS instructions discuss whether the organization acted reasonably and in good faith and whether relief would prejudice the government's interests.
  5. Get professional advice when the earlier date matters. Donations, grants, tax returns, or prior operations during the gap can make the consequences fact-specific.
Do not wait until month 27 to begin. The board still needs accurate organizing language, an EIN, governance decisions, activity descriptions, financial information, the correct application choice, and funds for the Pay.gov user fee.

Important exceptions and separate deadlines

The IRS states that churches, certain church-related organizations, and organizations whose gross receipts are normally not more than $5,000 may be considered exempt without filing Form 1023 or Form 1023-EZ, although they may choose to apply for a determination letter. Confirm the exact exception before relying on it.

The application timeline does not pause annual reporting. The current Form 1023-EZ instructions say an organization that is required to file Form 990, Form 990-EZ, Form 990-PF, or Form 990-N must file even when its exemption application has not been submitted or remains pending.

Prepare before submitting

  • Confirm the legal formation date and exact legal name.
  • Review the Articles for acceptable purpose and dissolution provisions.
  • Obtain the EIN and preserve the confirmation notice.
  • Complete the current Form 1023-EZ Eligibility Worksheet before choosing a form.
  • Prepare accurate activity narratives and actual or projected financial data.

  • Submit through Pay.gov and retain the complete application and receipt.

Frequently asked questions

How long after forming a nonprofit do I have to file Form 1023?

The IRS generally provides a 27-month window after the end of the month in which the organization was legally formed. If the application is timely and approved, exemption generally takes effect on the legal formation date.

Can a nonprofit file Form 1023 after 27 months?

Yes. Filing after 27 months is generally still possible, but the effective date of exemption is normally the application submission date unless the IRS grants an earlier date under an applicable exception or relief provision.

Does the rule also apply to Form 1023-EZ?

Yes. The current Form 1023-EZ instructions use the same general 27-month rule. An organization filing late that wants to request an earlier effective date must use the full Form 1023 rather than Form 1023-EZ.

Does filing Form 1023 pause Form 990 requirements?

No. The IRS says an organization required to file a Form 990-series return or Form 990-N must do so even if its exemption application has not been filed or is still pending.
