Our Commitment to Transparency

As a federally registered tax-exempt organization, CO-LIB STAFF ASSOCIATION believes that transparency builds trust. We make the following information publicly available:

About Form 990-N

Form 990-N, also known as the e-Postcard, is the annual notice that small tax-exempt organizations file with the IRS. It confirms that the organization is still operating and reports that gross receipts are $50,000 or less. Organizations that fail to file for three consecutive years may have their tax-exempt status automatically revoked.

CO-LIB STAFF ASSOCIATION has maintained its active status and continues to file Form 990-N annually. Our most recent filing covers tax year 2025 (January 1, 2025 through December 31, 2025).
