Mailing Address Change

Most taxpayers are unaware that maintaining the mailing address is the responsibility of the Assessor, not the Tax Collector.

It is essential that we have your correct mailing address. Notification of assessments, tax bills and all other tax related correspondence will be mailed to that address.

If you wish to change your mailing address, please complete the Mailing Address Change Request form and return it to our office. Please note that we maintain only one mailing address for all your assessment and tax related mail.

Select the Business Personal Property form if you own a business and are not the owner of the real property at your business location.
