Introduction

On July 1, 1983, California State Law was changed to require the reassessment of property as of the first day of the month following an ownership change or the completion of new construction. In most cases, this reassessment results in one or possibly two Secured Supplemental tax bills being sent to the property owner in addition to the annual Secured property tax bill.

The Assessor first determines the new value of the property based on current market values. The Assessor then calculates the difference between the new value (set at the time of purchase or completion of new construction) and the old value (set on January 1 of the previous fiscal year). The result is the supplemental assessed value. Once the new assessed value of your property has been determined, the Assessor will send you a notification.

General Rate

This is the decimal percentage rate that the taxes are based on.

Tax Rate Area

The Tax Rate Area in which the property is located. Special districts, such as schools, cities, and water districts are collecting money for voter approved bonds and special assessments. Because not all of the bond rates are the same, you pay taxes according to which bonds were approved in the area where the property is located.

Parcel or ID Number

This number is used to identify the property. This numbering system was invented by the Assessor's Office and includes the map book, page number, the block on the page and the parcel.

Prop 13 Maximum 1% Tax

Governed by the Revenue and Taxation Code for the State of California, the amount calculated on this line is equal to 1% of the Net Total of the assessed net value of your property. For questions regarding Proposition 13 contact the Ventura County Assessor's office at (805) 654-2181.

Bonds

The items listed here are approved by the voting public prior to appearing on your tax bill. For information regarding any of your bonds, contact the taxing district at the telephone number provided next to the bond name on your tax bill. The Ventura County Treasurer-Tax Collector has no jurisdiction regarding the bonds listed on your bill.

Total

This is the Total amount of tax you will be paying for the fiscal year. The amount due here is equal to the total amount calculated for Proposition 13 tax and all voter approved bonds.

1st Installment and 2nd Installment

The date on which supplemental tax bills become delinquent varies depending upon when they are created by the Auditor. If the bill is created between July 1 and October 30, the taxes become delinquent at the end of the business day on December 10 for the first installment and at the end of the business day on April 10 for the second installment. If the bill is created between November 1 and June 30, the delinquency dates, which are printed on the bill are determined as follows: The first installment is delinquent at the end of the business day on the last day of the month following the month the bill was mailed; the second installment is delinquent at the end of the business day on the last day of the fourth month after the first installment delinquency date. Penalties of 10% are added to any installment, which is not paid on time, and an additional $30 charge is added to a late second installment.
