Tax Definitions/Terms
Secured Property Taxes
The term "secured" refers to taxes that are assessed against real property (e.g., land or structures). The tax bill creates a lien that is "secured" by the land/structure even though no document is officially recorded. This means that if the tax remains unpaid after a period of five (5) years, the property may be sold to cover the taxes owed. 

Unsecured Property Taxes
The term "unsecured" refers to property that can be relocated and is not real estate, such as business equipment, equipment, fixtures, boats, or airplanes. If the unsecured tax is not paid, a lien is filed against the owner, not the property.

Supplemental Taxes
"Supplemental" taxes are additional secured taxes that are assessed when property undergoes a change in ownership or new construction. The additional tax is owed because the County Assessor is required to immediately adjust the January 1 value to reflect the new value of the property. The supplemental tax is adjusted for the number of months left in the fiscal year. This supplemental tax bill represents the tax due on the difference between the old and new values.

Special Assessments
Special Assessments arise because various governmental agencies provide services to the property and are shown on your tax bill like: Water, Sewer, Roads & Maintenance, Lighting, etc
