Secured Property Tax Information


What are "secured" property taxes?

The term "secured" simply means that taxes are assessed against real property (land or structures). The tax is a lien that is "secured" by the land or structure. If the taxes remain unpaid after a period of five years, the property may be sold by the Tax Collector to cover the taxes owed.

When is the secured tax assessed?

The Assessor establishes the value of unsecured property on January 1. This date is often referred to as the tax lien date.

How are the secured taxes determined?

The January 1 value is multiplied by the tax rate (usually 1 percent plus voter approved assessments).

What period of time does a secured tax bill cover?

A secured tax bill covers a fiscal year. The fiscal year begins July 1 and ends on June 30 of the following calendar year.

When should I expect my secured tax bill?

Every year, the Tax Collector mails the secured tax bills in October. If you do not receive a tax bill by November 1, or if you recently purchased a property, you may access your tax bill online. You can also request a duplicate copy by calling 530-538-7701 or by sending an e-mail to

When are secured property taxes due?

The 1st installment is due on November 1 with a grace period until 5:00 p.m. on December 10 to pay without penalty. The second installment is due on February 1 with a grace period until 5:00 p.m. on April 10 to pay without penalty.
