2009 - 460,000 Assessment Notification Cards mailed

Earlier today the Santa Clara County Assessor’s Office mailed more than 460,000 assessment notification cards, providing property owners the opportunity to review their property’s taxable value before the 2009-10 property tax bill is generated, and mailed in September. The Assessor has proactively reduced the assessed value of just over 90,000 residential properties, a temporary reduction resulting in lower 2009-2010 property taxes. The average reduction for each residential property is $170,000 and the total assessed value reduction is expected to exceed $17 billion.


Property owners who receive the notification card and believe that the market value of their property, as of January 1, 2009, is less than the amount shown on the card are encouraged to contact the Assessor’s office by August 15, 2009, to request a review. The fastest way to complete a request for a review is through the Assessor’s website at www.sccassessor.org/prop8.

Assessed value reductions result from the Assessor’s comparison of the factored base year value (typically the assessed value at the time of purchase plus increases of no more than 2 percent annually) to the market value as of the lien (valuation) date, January 1. “The law requires assessors to look at market values as of January 1; so even if the market value has continued to decline through June, the Assessor must use the value as of January 1,” said Assessor Larry Stone.

“While this process can be confusing, requesting a review of your assessed value is quick and easy,” said Stone. “Basically, if you believe that the market value of your property, as of January 1, is substantially less than the value on your notice card, I encourage you go online to www.sccassessor.org/prop8 and complete a simple request for review before our August 15 deadline.” The form can be completed by the owner, entirely on-line. In addition to the form, there is a detailed PowerPoint presentation to help taxpayers better understand the legal basis for temporary assessed value reductions and to determine their eligibility. Property owners can also contact the Assessor’s Office at (408) 299-5300; fax a completed form to (408) 299-3015 or email the assessor a request to This email address is being protected from spambots.

Last year 8,000 taxpayers requested a reduction and approximately half were granted relief. During the review period property owners will be asked to substantiate the requested reductions with market examples of similar properties that sold shortly before or after January 1.

Santa Clara County is one of only nine counties in California that mail cards to all 460,000 property owners. By encouraging taxpayers to contact the Assessor’s Office before the Tax Collector prepares the tax bills for mailing in September, the Assessor is able to complete a more accurate assessment roll thus reducing the number of formal assessment appeals, which are time consuming and expensive for both the Assessor and the property owner.

A sample notification card is attached. The front of the card contains the property’s address, full cash value and parcel number. The back of the card includes important information regarding what to do if you do not agree with the value, exemptions for which the property may qualify and contact information for our office.
