(Redwood City, CA) San Mateo County Chief Elections Officer & Assessor-County Clerk-Recorder Mark Church reminded county property owners who wish to seek property tax relief for the 2010 tax year through the Decline in Value program of the deadline to apply for a property review. “The last day to apply for a 2010 decline in value review for properties in San Mateo County is February 15,” Church stated.

State law (Proposition 8) provides property tax relief to property owners if the market value of a property falls below its assessed value as of January 1 (the lien date for each tax year).  This usually happens when (and if) there is a substantial and sustained drop in the real estate market as both the county and the country have experienced these past few years.

If a property’s market value is less than its assessed value, the property is eligible for temporary property tax relief through the Decline in Value Program. The Assessor must review the property to determine if it is eligible, and if it is, the property is temporarily reassessed at its market value as of January 1.  This reassessment automatically lowers the property taxes for that year.

Assessors must review all properties in this program every year to determine if a property remains eligible for the program.  When the property’s market value equals or exceeds its factored base year value (usually the purchase price plus annual inflation adjustments limited to 2 percent per year), the factored base year value is restored and the property is removed from the program.  If a property owner disagrees with the Assessor’s valuation, they can request a second review. If the property owner and Assessor cannot agree on the value of a property, the formal resolution of the property’s value rests with the Assessment Appeals Board.

Assessor Church also reminded property owners that, “The Assessor’s Office conducts all Decline in Value Reviews free of charge.  A property owner can request a review by filling out the simple, online application or calling or stopping by the office to obtain a paper form.”

“Independent firms will offer to provide this service to property owners, but they charge a fee and they cannot guarantee a reduction,” explained Assessor Church. “Involving a second party takes more time,” he added.

Property taxes are due on February 1 and delinquent on April 10. Property owners are responsible for paying the property taxes due and making the payments on time. Applying for a Decline in Value Review will NOT exempt a taxpayer from paying the taxes when due.

Here are four easy ways that a property owner can apply for a Decline in Value Review:

  • Complete the online request form on the Assessor’s website
  • Download and print the request form on the Assessor’s website
  • Call the office and ask for a request form by mail
  • Visit the Assessor’s Office in person
