The assessor may not approve a property tax exemption claim until the claimant has been issued a valid organizational clearance certificate pursuant to Section 254.6. Financial statements shall be submitted only if requested in writing by the assessor.
Prior to the lien date, the assessor shall annually mail a notice to every applicant relieved of the requirement of filing an annual application by this subdivision.
The notice shall be in a form and contain that information that the board may prescribe, after consultation with the California Assessors' Association, and shall set forth the circumstances under which the property may no longer be eligible for exemption, and advise the applicant of the duty to inform the assessor if the property is no longer eligible for exemption.
The notice shall inform any applicant desiring to maintain eligibility for the welfare exemption under Section 214.15 or Section 231 for the next fiscal year of the procedure to reaffirm exemption eligibility. The failure to reaffirm eligibility for the exemption does not of itself constitute a waiver of exemption as called for by the California Constitution, but may result in additional contact by the assessor to verify exempt activity.
