Revaluation is a process by which all property tax assessments within a taxing jurisdiction (Orange County) are reassessed to their market value as of a specific revaluation date. It also is sometimes called a reappraisal or mass appraisal. The tax office, in this process, reassesses all real property (land, buildings and other improvements to the land) as of the revaluation date.
Arms-length market sales are used to estimate new tax assessments during this process as well as other market data such as income/expense information and market building cost information. This updated tax assessment is effective, generally, until the next countywide revaluation. Orange County’s next planned revaluation date is January 01, 2021, and tax assessments should reflect market value as of that date once the revaluation is completed.
