Sample Property Tax Report for a Sonoma County, CA property

The California Constitution mandates that all property is subject to taxation unless otherwise exempted by state or federal law. Proposition 13, enacted in 1978, forms the basis for the current property tax laws.

Assessed Market Value

Assessed value is calculated based on market value using a base year value. A property's original base value is its 1975-1976 market value and can be adjusted each year by no more than 2% to account for inflation. However, if there has been a change in ownership or completed new construction, the new assessed value will be the market value of the property as of the date that if changed ownership or was newly constructed.

Land value $136,617
Structural improvement value + $205,930
Assessed value = $342,547
Exemptions And Taxable Value

Taxable value represents the assessed value less any tax exemptions that apply. Sonoma County provides a variety of full and partial exemptions that may lower the property's tax bill.

We have no information about whether any exemptions currently apply to this property. Therefore, the taxable value will be equal to the assessed value.

Property Tax

Property tax is calculated by multiplying the property's taxable value by all the tax rates applicable to it and is an estimate of what an owner not benefiting from any exemptions would pay.
Actual taxes might differ from the figures displayed here due to various abatement and financial assistance programs, or to non ad-valorem taxes levied as special taxes.
