Return the notice to the Cochise County Treasurer's Office:
P.O. Box 1778
Bisbee, AZ 85603
Include a note that the property has been sold. Also list any known information such as the name of the new owner or the date of sale. It is also helpful to advise the Treasurer if the new owner lives at the same address. This helps get the tax notice to the new owner as fast as possible.
The Assessor's office is responsible for listing ownership as well as values. This office works on a two-year cycle and has many cut-off dates to process changes; therefore not all sales are reflected on the tax notice. Contact the Assessor to verify that a record of your sale has been received or to verify the Assessor's timeline for changes.
