As part of our effort to support a cleaner and healthier environment by taking advantage of today's technology, the Tax Collector's Office now offers SECURED PROPERTY TAX bill notifications by e-mail.

To participate in this voluntary program, all you need to do is SIGN UP by completing the New User Profile and adding parcel numbers to the APN list that will be sent to you in September each year.

In addition to the annual e-mail notification, we will also send you a reminder notification prior to the delinquent date of each installment. This will be particularly helpful if you have multiple bills to keep up with and pay.

The e-mail notification is free and will link you to your on-line tax bill where you can view/print its details and pay the installments, all in the convenience of your home or work place and without the stress of late or lost mail.
