The assessor shall provide the information, which shall not include social security numbers. Any information provided to the tax collector pursuant to this subdivision shall not become a public record and shall not be open to public inspection. The tax collector shall reimburse the assessor for the actual and reasonable costs incurred by the assessor for providing the information to administer this subdivision. The tax collector shall add the costs described in the preceding sentence to the assessee’s delinquent taxes and include the costs incurred subject to Sections 4112 and 4672.2.
