Example of Multi- Property Notice
(Click to Enlarge)		 An official notice of assessed value is sent to property owners by the County Assessor annually to notify property owners of the assessed value on which the following year's property taxes will be based. The assessed values represent market value as of January 1st of the assessment year. Property owners have until July 1st or 60 days from the date of the notice (whichever is later) to file an appeal with the Board of Equalization (BOE), however property owners are encouraged to contact the Assessor's office to discuss their new assessment before filing an appeal with the BOE.


Tax Statement

The assessed value on the tax statement is the value of the property as of Jan. 1st of the prior year. First half taxes are due April 30th and second half taxes are due Oct. 31st annually.
