The Standard California Secured Property Tax Schedule<\/h2>\n\n\n\n

In California, secured property taxes are managed by your local County Tax Collector\u2019s Office<\/strong> and are payable in two installments, adhering to a “first half\/second half” schedule:<\/p>\n\n\n\n

Installment<\/strong><\/td>Due Date<\/strong><\/td>Delinquency Date (10% Penalty Applied)<\/strong><\/td><\/tr><\/thead>
First Installment<\/strong><\/td>November 1<\/td>December 10<\/strong><\/td><\/tr>

Crucial Deadline Note:<\/p>\n\n\n\n

Escrow vs. Owner: Who is Responsible for Payment?<\/h2>\n\n\n\n

What are Supplemental Taxes?<\/h4>\n\n\n\n

When a property is sold, it is reassessed at the new purchase price. Supplemental Taxes are a one-time bill covering the difference in tax value between the old assessment and the new one, prorated from the day your escrow closed until the end of the fiscal tax year (June 30).<\/p>\n\n\n\n

Why Your Lender Won\u2019t Pay This Bill:<\/strong><\/p>\n\n\n\n

Supplemental Tax Bills are mailed directly to the property owner, not the lender, and often arrive separately<\/em> from the standard annual bills. Lenders typically do not automatically account for or pay this unpredictable bill from your impound account.<\/p>\n\n\n\n

How to Manage Your Supplemental Tax Bill:<\/h3>\n\n\n\n
