Reassessment notices for properties in Thornton were mailed to property owners on August 21, 2020. The property values on these notices have been adjusted, when appropriate, with a COVID-19 Adjustment based on our Office's estimates of economic effects of COVID-19.
Note: Due to a processing error, some single-family home parcels did not receive the COVID Adjustment calculated for homes in their neighborhood. The Assessor’s Office will correct this processing error automatically. Affected taxpayers do not need to take any action. Read more here (Español).
