Annual Notice of Assessed Value

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.

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? 

Answer: Please pay your property tax bill as issued by the Office of the Treasurer & Tax Collector. When our office processes your sale or new construction, we will issue notices of supplemental assessment, 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, or a refund if your new taxable value turns out to be less than the annual assessed value.

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.
