California Property Tax Basics for Home Buyers
Understand assessed value, reassessment, supplemental bills, and housing cost.
The basics
California property taxes are generally based on assessed value. A purchase can trigger reassessment, while supplemental bills may follow a change in ownership or new construction. Timing and amounts vary.
Plan the monthly cost
Taxes may be collected through an impound account or paid directly. Online estimates can differ from the actual bill because they may use old assessed values, incomplete data, or different assumptions.
Ask the county assessor or tax collector for property-specific information. For general California information, review the California Board of Equalization and applicable county sources.
