Nonprofit organizations with 501(c) status often qualify for valuable property tax exemptions at the state and local level—but securing those exemptions requires clear, compliant documentation for county assessors and tax authorities. This Tax Exemption Affidavit template is designed specifically for nonprofits applying for property tax relief, ensuring you capture all the information assessors need in a format that's easy to complete, review and submit.

Built for nonprofit administrators and board members

Whether you're a nonprofit director, finance officer, or board treasurer, this template walks you through the sworn statement process with structured fields for IRS determination letters, charitable purpose narratives, board member rosters and property use details. The form ensures compliance with county assessor requirements while maintaining a professional, organized presentation.

What makes this template work

This affidavit template collects essential documentation including 501(c) status proof, detailed descriptions of charitable activities, current board member information with contact details, property descriptions, and sworn declarations.
