Cal. RTC § 205.6

In order to prevent duplications of the disabled veterans’ property tax exemption within the state and improper overlapping with other benefits provided by law, county assessors may supply information from disabled veterans’ property tax exemption claims and county records as is specified by written request of the board necessary to fully identify all disabled veterans’ property tax exemption claims allowed by the assessors. The board may specify that the information include all or a part of the names and social security numbers of claimants and spouses and the identity and location of the dwelling to which the exemption applies. The information may be required in the form of data-processing media or other media and in such format as is compatible with the recordkeeping processes of the counties and the auditing procedures of the state.
