A determination letter is the IRS notice recognizing the organization’s tax-exempt status and usually stating its foundation classification and effective date. Organizations commonly keep it with permanent records and provide copies to banks, grantmakers, donors, or other parties that need evidence of exemption.

After an exemption application is submitted, the IRS may approve it as filed or request more information; processing time varies by application type and complexity, and the IRS's own processing-time page is the current source to check rather than a fixed number of days. Save the submitted application, Pay.gov confirmation, governing documents, and every IRS notice in one file, and monitor the mailing address so requests aren't missed. Annual filing and state obligations continue during the review, so waiting for a determination letter doesn't pause other compliance deadlines.

Exact state requirements can differ, so the current state filing instructions control any state-specific step.

How Beacon Nonprofit can help: Beacon's guided application service can help the organization reach the point where the IRS issues its determination and can keep the application records organized for the nonprofit's files. Beacon does not issue the determination letter or control its content; the IRS makes the exemption and classification decision. Beacon's role is administrative formation and filing support: government agencies control approval, processing times, and legal or tax determinations, and specialized operational matters may require a qualified professional outside Beacon's service scope. Depending on the selected package, the Beacon records available to the organization can include the approved state formation documents and, with BeaconComplete, EIN assistance, corporate bylaws, registered agent service, and the 501(c)(3) application materials prepared through the service.
