Institutional and non-profit exemptions
The Legislature has the authority to exempt owned real or personal property (1) used exclusively for religious, hospital, charitable, or scientific purposes, and (2) owned or held in trust by nonprofit organizations operating for those purposes.
The Marin County Assessor co-administers these exemptions with the State Board of Equalization, and both the organization and the property must qualify under the State requirements.
Required documents for welfare exemption
- An Organizational Clearance Certificate from the BOE
- A Supplemental Clearance Certificate from the BOE (If applicable for low-income housing)
- A completed welfare claim form for each requested tax year.
