Terms & Conditions


NOTE: Parcel numbers will be removed automatically from your e-Billing account whenever there is a change of deed to the property. You will need to re-enter it to appear in your e-mail notification.

The e-Billing service enables you to view and pay your Secured Property Tax bill on line using the Internet. By subscribing to e-Billing, you agree that you will no longer receive a paper tax bill by mail from the County. The Contra Costa County Tax Collector, hereafter referred to as the Tax Collector, is committed to ensuring your on-line billing is always available. However, in the event that you do not retrieve or cannot view your tax bill, the Tax Collector cannot be held liable. The responsibility of paying your tax bill in a timely manner remains yours. In the event of a discrepancy between an on-line tax bill and the Tax Collector's billing records, the Tax Collector's billing records will always prevail.

You must have a valid e-mail account to use e-Billing. You must provide us with the correct and currently valid address of the e-mail account to which you would like notification of your tax bill availability to be sent. The accuracy of that e-mail address is entirely your responsibility and in particular, but without limitation, should that e-mail account ever become invalid or should you wish notification of your tax bill availability to be sent to a different e-mail account it shall be your responsibility to notify the Tax Collector's Office. You shall remain fully liable for any tax bills of which notification has been sent to your previous e-mail address.

Your password should be kept secret, and the Tax Collector's Office accepts no responsibility or liability in the event that your password is used by an unauthorized user to access your account. The Tax Collector's Office accepts no responsibility or liability in the event that any correspondence informing you of your password is opened or read by anyone else. You should contact us immediately if your password has been compromised.

All Secured Property Tax bills of which notification is sent to you by e-mail shall be due and payable on the "date due" of each bill. You shall remain fully responsible and liable to pay any bills of which notification has been sent to the e-mail address you have specified regardless of whether or not you access that e-mail account and read the relevant e-mail, are disconnected from your e-mail account (for any reason and whether by the Tax Collector's Office or otherwise) or for any other reason (other than Tax Collector's Office's negligence) fail to read the relevant notification.

Any material downloaded or otherwise obtained by your using the e-Billing service is done at your discretion and risk and you are solely responsible for any damages to your computer system or loss of data that result from downloading of such material.
