Source and verification
Penalty for late payment (PLP) of real estate taxes is 10% of the amount due and is applied automatically after the due date. Real estate is paid in two installments, so a penalty will be applied for each installment that is late. For Tax Year 2020 ONLY, the Board of Supervisors reduced that rate to 5%. Interest at 1% per year will apply.
