Annual Notice of Assessed Value
Informational letter to notify you of your property’s assessed value (taxable) each year.
What to expect
Our office typically sends a Notice of Assessed Value (NAV) in July to the property taxpayer on record. This notice is not a bill and does not require payment. The property’s assessed value is used to determine the property taxes for the upcoming year.
This is an informational letter to notify you of your property’s assessed value. The assessed value, minus exemptions, is the basis for your annual property taxes. The tax bill sent by the Treasurer & Tax Collector typically covers the fiscal year starting July 1 and ending June 30, with the 1st payment due in December and 2nd payment due in April.
When our office processes your sale or new construction, we will issue a supplemental assessment notice, which will notify you of the difference between the adjusted value (Proposition 13 value) and your purchase price or the market value of your new construction. You will then receive a supplemental tax bill from the Office of the Treasurer & Tax Collector to cover that difference in value.

Questions about your NAV
If you have a question or disagree with your NAV, please contact our office as soon as possible.
Frequently asked questions
Question: The Assessed value shown on my NAV does not appear to take into consideration my recent purchase price or the added value of my new construction, what do I do?
Depending on the timing of your assessable event, the likeliest explanations are:
For assessable events after January 1, 2025, your updated assessed value is normally first reflected the following calendar year, so on your 2026 Notice of Assessed Value, at the earliest.
For assessable events before January 1, 2025, your updated assessed value is normally reflected on your 2025 Notice of Assessed Value. Unfortunately, your assessable event may not have been processed by our Office in time for this year’s Notices due to an unprecedented increase in workload driven by the pandemic. We are committed to processing your event as soon as possible. Should you have any questions or concerns, please do not hesitate to reach out.
After we have processed your case and have made changes to our records, including updating the assessment, we will issue you a Notice of Supplemental and/or Escape Assessment. This letter will notify you of the difference between the prior value and the market value at the time of purchase or market value of your new construction. You will then receive a corresponding tax bill from the Office of the Treasurer & Tax Collector (a separate office) to cover that difference in value.
Note: Please pay the taxes billed by the Office of the Treasurer & Tax Collector or you may incur penalties. Remember to set aside funds to pay for any increase in taxes that are not yet reflected in the records.
Question: How is property tax determined from the assessed value?
Answer: Usually, the factored base year value, minus eligible exemptions, is the net assessed value which is the basis for your property taxes. Your net assessed value is not the amount you owe in property tax. Your property taxes are calculated by taking the property’s net assessed value multiplied by the yearly tax rate. Please note, you will receive your tax bill by November 1 of each calendar year from the Office of the Treasurer & Tax Collector.
If you no longer own the property indicated on the NAV as of June 30, please disregard the notice. If you sold the property after June 30, you may still receive a tax bill with the portion you are responsible for during your ownership between July 1 - June 30.
