Every year, the Bexar County Appraisal District (BCAD) decides the property value of your home. April 15 is the primary deadline for filing a personal property rendition. This report is confidential and not open to public inspection; disclosure is permitted pursu- ant to the terms of Tax Code Section 22.27. When completing the rendition, the property may be reported using a good faith estimate of the market value or the historical cost when new. The Texas Property Tax Code for many years had required owners of business personal property (BPP) to annually render those assets used in a business.
