    The IRS requires all companies to have a current W-9 on file prior to making any payments including property taxes. If you require a W-9 from the County in order for your business to process payment for your secured or unsecured property tax bills, please e-mail your request to with your fax number and the type of invoice you need to pay (see list below).

    P.O. Box 1438       Property Tax
    P.O. Box 4005       Accounts Receivable/Weights & Measures
    P.O. Box 1959       Animal Care
    P.O. Box 4515       Other

    We process these requests weekly. If you have questions on the W-9, please contact us at (714) 834-7625.

    Individual taxpayers should not be requesting a W-9, only businesses. We do not issue 1099's for property tax payments.
