COVID-19 impact on assessed values – California law, in part, requires that the assessed value of all assessable property is to be determined annually as of a specified value date, January 1, also known as the “lien date”. If the market value of a property on January 1, is less than the assessed value of the property on January 1, the assessor may temporarily reduce the assessed value to market value. For accuracy, market value appraisals are based on real estate market data for time periods as close to the date of value (January 1) as possible.
Since COVID-19 did not cause a disruption until March 2020, nearly three months past the January 1 value date, data reflecting possible impacts to real estate market conditions and property values, will not impact assessed values for January 1, 2020 and billed by the Tax Collector in this year’s annual 2020/2021 tax bill. Declines in market value of property due to effects of COVID-19, if any, will be proactively addressed effective January 1, 2021 and billed by the Tax Collector in next year’s annual 2021/2022 tax bill.
The 2020/2021 assessed values are available for review beginning July 2. Please review your assessed value closely and contact us with questions or concerns. The Assessor’s informal review filing period is July 2 – December 30.

Chart - Prop 13 and Prop 8: How Property Values Are Assessed
Proposition 8, passed in November 1978, amended Proposition 13 to recognize declines in market value for property tax purposes. Once a decline in value is recognized, the Assessor is required to annually enroll the lower of a property's market value or its Proposition 13 factored value. (Ref. RTC 51)
Decline in market value, Prop 8 assessments, are TEMPORARY reductions that recognize the fact that the market value of a property has fallen. Once a Prop 8 reduced value has been enrolled, that property’s value must be reviewed each year and its assessed value will go up or down in tandem with its market value as of the January 1 property tax lien date. Detailed information on the Proposition 8 process and how it may affect your property may be found on the Decline in Market Value (Prop 8) Overview page.
